1 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Fixed the silc_verify_public_key client operation function to
4 save the public keys differently. The fingerprint is now
5 used as filename and not the hostname. This way also the
6 client keys are saved uniquely and not with hostnames. The
7 affected file is silc/client_ops.c.
9 * Trimmed the silc_hash_fingerprint function to remove extra
10 whitespaces from the end of the fingerprint. The affected
11 file is lib/silccrypt/silchash.c.
15 * Added silc_cipher_register_default function to register all
16 default ciphers. It can be used when configuration files
17 does not exist and the application does not want any specific
18 ciphers in any specific order.
20 The SilcDList is now used as silc_cipher_list dynamically
21 allocated cipher list. Removed the static list all together
22 and now all ciphers must be allocated to the dynamic list.
23 The silc_cipher_alloc routine was changed to check only the
26 All silc_cipher_* routines that used to return int returns
29 The affected files lib/silccrypt/silccrypt.[ch].
31 * The same thing was done to silc_hash_* as for silc_cipher_*
32 routines. Affected files lib/silccrypt/silchash.[ch].
34 * The same thing was done to silc_pkcs_* as for silc_cipher_*
35 routines. Affected files lib/silccrypt/silcpkcs.[ch].
36 Added also silc_pkcs_[un]register[_default] functions.
37 Removed the data_context from the PKCS API.
39 * Added silc_hmac_register_default function to register default
40 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
41 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
42 to unregister all hmacs at once.
44 * Register the default ciphers, hash functions, PKCSs and HMACs
45 if client's configuration file does not exist. The affected
48 * The client did not load the hash functions from the SIM
49 modules at all. Added support for this. Affected file is
52 * When decoding public key with silc_pkcs_public_key_decode, check
53 the supported algorithm only if PKCS are registered. Affected
54 file lib/silccrypt/silcpkcs.c. The same was done with the
55 silc_pkcs_private_key_decode.
57 * Fixed the SILC List routines to keep the list always in order.
58 It used to change the list's order when traversing the list but
59 not it preserves the order. Affected file lib/trq/silclist.h.
61 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
63 * Added the client library to use the SilcSocketConnection's
64 reference counter (by silc_socket_dup) to prevent the bug that
65 the socket object may be freed underneath async operation.
67 * The name resolv library checking fixes in the configure.in.pre.
70 * Created new version of the protocol drafts for future
71 development. The -03 drafts are the ones that will be changed
72 in the trunk now and the -02 will remain as they are.
74 * Send list of CUMODE notifys to the router when announcing
75 the channel users to the router. Affected file silcd/server.c.
76 If the router receiving channel founder CUMODE for a channel
77 that already has channel founder it will send CUMODE notify
78 to the sender to remove the channel founder rights from the
79 announced client. Affected file silcd/packet_receive.c.
81 * The CUMODE notify may now use Server ID as well as the entity
82 who changes the mode. Updated protocool specs.
84 * Updated INSTALL and README files.
86 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
88 * New web pages in the http://silc.pspt.fi. The pages was
93 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
95 * Implemented the [DenyConnectin] config section in the server.
96 Added silc_server_config_denied_conn to check whether incoming
97 connection is denied. Affected file silcd/serverconfig.[ch].
99 * Do not check the ports when checking the incoming configuration
100 data if the port is 0, meaning any. Affected file is
101 silcd/serverconfig.c.
103 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
105 * Fixed buffer overflow in silc_string_compare in the file
106 lib/silcutil/silcutil.c.
108 * Fixed double free in silc_server_command_leave in the file
111 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
113 * Fixed the version checking in the server. Affected file is
116 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
118 * Fixed the configuration data fetching when accepting new
119 connections in the server. Affected file silcd/server.c.
121 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
123 * Added `sender_entry' argument to the function
124 silc_server_packet_relay_to_channel so that we can check
125 whether some destination actually belongs to the same route
126 the sender belongs (ie, we must not resend the packet to the
127 sender). Affected file silcd/packet_send.[ch].
129 * Added `servername' field to the SilcClientEntry in the server
130 to hold the name of the server where client is from. Affected
131 file is silcd/idlist.h.
133 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
135 * Moved the channel message encrypting in the router betwen
136 router connections from silc_server_channel_message to the
137 silc_server_packet_relay_to_channel since we want to check
138 whether we have anybody channel before encrypting anything.
139 Affected files silcd/packet_[receive/send].c.
141 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
143 * Fixed the [AdminConnection] server config section to support
144 multiple entries. Affected file silcd/serverconfig.c.
146 * Added support into the server to check the validity of the
147 incoming connection before executing any KE or authentication
150 * The connection configuration is now saved to the KE and
151 connection auth protocol contexts and not fetched anymore in
152 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
154 * The local hosts listenning address and port is also resolved
155 now when starting the server. We want to have the socket object
156 to include the real address and port for the listener. Added
157 new function silc_net_check_local_by_sock into the files
158 lib/silcutil/silcnet.[ch].
160 * Fixed a broadcast bug in server -> do not broadcast if we
163 * Fixed a routing bug. Do not route broadcast packets ever.
164 Broadcast packets must be processed always and not routed since
165 they may be destined to some other host than yourself and thus
166 would get routed without no good reason. Affected file is
169 * Added function silc_server_config_is_primary_route to check
170 whether primary router connection has been configured (a router
171 configuration that we are initiating). If there is not, we
172 will assume that there is only two routers in the SILC network
173 and we will use the incoming router connection as our primary
174 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
176 * Changed the order of the broadcasting. Broadcast _after_ the
177 packet has been processed not before. Affected file is
180 * Fixed a [ClientConnection] parsing bug. The port was never
181 parsed correctly thus resulting to port 0. Affected file
182 silcd/serverconfig.c.
184 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
185 argument and did not set the broadcast packet flag. Affected
186 file silcd/packet_send.c. Fixed same bug in the function
187 silc_server_send_notify as well.
189 * If we receive NEW_ID packet for our own ID in the server, ignore
192 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
196 * Removed the nickname from the Private Message Payload.
197 Updated the code and the protocol specs.
199 * Updated protocol specs for submitting to the IETF.
201 * Tweaked the Random Number Generator a bit. Affected file
202 lib/silccrypt/silcrng.c. Exported a new function
203 silc_rng_[global]_add_noise which can be used to add more
206 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
208 * Do not parse packets with different timeout when protocol
209 is active -> may cause problem with rekey. Affected file
212 * When server receives signoff notify it must not create
213 new channel key if the client is on any channels since the
214 sender of the signoff notify will create it.
216 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
218 * Added printing of error messages during SKE protocol from the
219 failure packet sent by server during SKE. Affected file
222 * Removed the client's failure_callback handling with timeout
223 and handle it immediately when received.
225 * The SKE library returned wrong type in SUCCESS and FAILURE
226 packets. They must be 32 bit MSB not 16 bit MSB.
228 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
230 * Ok, rewrote the logic of the re-key and now it seems to work.
231 I tested it on high traffic with frequent re-keys without
232 problems. Added hmac_receive (and renamed hmac to hmac_send)
233 in SilcClientConnection in lib/silcclient/client.h and
234 in SilcIDListData in silcd/idlist.h. Also, removed the
235 SilcPacketParserContext's cipher and hmac fields as they are
236 not needed anymore and actually caused some problems when
237 the ciphers and hmac's changed underneath the packet parser.
239 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
241 * If re-key protocol is active then process the incoming packets
242 synchronously since we must assure that icoming packets encrypted
243 with the old key is processed before the new keys is set to
244 use. This is true other packets than for REKEY packets.
245 Affected file silcd/server.c. The same was done to client library
246 as well, affected file lib/silcclient/client.c.
248 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
250 * Fixed bug in client and server to accept the force send if
251 the packet is send from silc_[server/client]_packet_process
252 function. Otherwise the packets are never delivered, oops.
254 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
256 * Disable force sending of packets when REKEY protocol is active.
257 We must assure that no packet is sent directly when rekey is
258 performed. All packets must be sent through packet queue.
259 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
260 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
261 function is silc_[server/client]_packet_send_real to check
264 * Replaced the SIM paths from example config files to
265 /usr/local/modules. Also, make install creates now
266 /usr/local/silc/logs directory to hold all the SILC server
269 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
271 * Made the configure.in.pre work on Solaris. Patch by salo.
273 * Made all ciphers compatible with non-x86 machines. Defined
274 CBC mode macros into lib/silccrypt/ciphers_def.h.
276 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
278 * Fixed the make install.
280 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
282 * When MAC computation fails the silc_packet_decrypt returned 0
283 even though it was supposed to return -1. Fixed this. The
284 affected file is lib/silccore/silcpacket.c.
286 * Do not replace the config files in /etc/silc (in make install)
287 if they already exist. Affected file ./Makefile.am.
289 * Do not send re-key packets immediately but through packet queue.
290 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
292 * Changed silc_net_check_host_by_sock to return FALSE if the
293 IP/DNS could not be resolved. Though, it returns the IP address
294 now even if it could not resolve it (but returns also FALSE).
295 Affected file lib/silcutil/silcnet.[ch].
297 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
299 * Added silc_pkcs_decode_identifier to decode the public key's
300 identifier. Affected file lib/silccrypt/silpkcs.[ch].
301 Added also silc_pkcs_free_identifier. Added also new context
302 SilcPublicKeyIdentifier.
304 * Added -S option to the silc client. It is used to dump the
305 contents of the specified public key file.
307 * Changed the PKCS api to return the public key length when
308 setting the public key.
310 * Fixed a fatal bug in the public and private key file loading.
311 Affected file lib/silccrypt/silcpkcs.c.
313 * Execute the packet parsing for client with zero (0) timeout
314 if the protocol is active. Affected file silcd/server.c.
316 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
318 * Made the key generation options to the silcd program. Added
319 -C option, equivalent to client's option.
321 * Added new [ServerKeys] config section to the server. It
322 configures the server's public and private key.
324 * Defined generic Public Key Payload into the protocol
325 specification to send specific type of public keys and
328 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
329 public key or certificate.
331 * Implemented the GETKEY command to the server and to the
332 client library and on user interface.
334 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
336 * Made preliminary `make install' work.
338 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
340 * Added SilcServerRekey context into silcd/idlist.h.
342 * Added the PFS support as defined in the specification to the
343 SKE protocol. Affected files lib/silcske/*.c.
345 * Added `ske_group' field to the SilcServerRekey context to hold
346 the number of the SKE group that is used with PFS in re-key.
347 Affected file silcd/idlist.h.
349 * Added PFS re-key support to the server. Affected file is
352 * Added silc_protocol_cancel to cancel execution of the next
353 state of the protocol. Affected file is
354 lib/silccore/silcprotocol.[ch].
356 * Added the re-key support with and without PFS to the client
357 library. Re-key is performed once in an hour, by default.
359 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
360 Added silc_client_rekey_callback and silc_client_rekey_final.
361 Affected files are lib/silcclient/protocol.[ch] and
362 lib/silcclient/client.[ch].
364 * Removed the `hmac_key' and `hmac_key_len' fields from the
365 SilcClientConnection structure; not needed. Affected file is
366 lib/silcclient/client.h.
370 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
372 * Do not ask whether user wants to use the negotiated private key
373 for private messages, just use it. Affected file is
374 silc/local_command.c.
376 * Added `send_enc_key' and `enc_key_len' fields to the
377 SilcIDListData structure since they are needed in the re-key
378 phase. Affected file is silcd/idlist.[ch].
380 * Implemented the simple re-key protocol into the server.
381 Affected files silcd/server.c and silcd/protocol.[ch]. The
382 re-key will be performed once in an hour, by default.
384 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
385 Added silc_server_rekey, silc_server_rekey_callback and
386 silc_server_rekey_final.
388 * Removed Tunneled flag from the protocol. Updated the code
389 and the specifications.
391 * Adde `pfs' field to the SilcIDListData to indicate whether
392 the PFS is to be performed in the re-key. Affected file is
395 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
397 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
398 int64 of at least the xintXX size. If void * is less that 4
399 bytes uint32 * will be used. Defined bool as boolean.
401 * Changed _ALL_ unsigned long and unsigned int to uint32,
402 unsgined short to uint16 in the source tree.
404 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
405 not handle clients that has entry->data.registered == FALSE.
406 They are not in the network anymore. Affected file is
409 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
411 * Implemented the sending of the SERVER_SIGNOFF notify in the
412 server. Affected file is silcd/server.c.
414 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
415 Added also silc_notify_payload_encode_args into the
416 lib/silccore/silcnotify.[ch].
418 * Implemented ther SERVER_SIGNOFF notify handling in the server.
419 Affected file silcd/packet_receive.c.
421 * Implemented the SERVER_SIGNOFF notify handling in the client
422 library. Affected file lib/silcclient/client_notify.c. Also,
423 implemnted the printing of the SERVER_SIGNOFF info to the
424 application. Affected file silc/client_ops.c.
426 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
427 if the deleting was successful. Affected file silcd/idlist.[ch].
429 * Added support for public key authentication in the connection
430 authentication protocol in the client library. Affected file
431 lib/silcclient/protocol.c.
433 * Changed the server's silc_idlist_get_clients_by_* interface
434 to support already allocated array so that new entries may be
435 added to pre-allocated array. Affected file silcd/idlist.[ch].
436 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
439 * All command reply functions in the server now calls the
440 pending command callback even if error occured. This way the
441 error will be delivered to the client as well. Affected files
442 silcd/command.c and silcd/command_reply.c.
444 * Fixed INFO command to return local server's info if no server
445 was provided. Affected file lib/silcclient/command.c.
447 * Removed RESTART command for good. Updated the code and the
450 * Rewrote parts of the task system. It is a bit simpler now.
451 Removed unsued task priorities. The affected files are
452 lib/silcutil/silctask.[ch].
454 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
456 * Moved the USERS printing from the library to the application.
457 Affected files lib/silcclient/command.c and silc/client_ops.c.
459 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
463 * Added channel key re-key support. The re-key is perfomed
464 only by the router and is done once in an hour. Added `rekey'
465 field to the SilcChannelEntry in the server. Affected files
466 silcd/server.c and silcd/idlist.h.
468 * Added silc_task_unregister_by_context into the file
469 lib/silcutil/silctask.[ch].
471 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
473 * Added SILC_UMODE_GONE mode to indicate when the client is not
474 present in the SILC network. Added also support to the local
475 command AWAY that will set this mode. Added support of showing
476 "xxx is gone" in WHOIS command. The USERS command shows the
479 * Fixed setting server and router operator privileges in the
480 server's UMODE command. Affected file silcd/command.c.
482 * Merged the SKE KE1 and KE2 payloads into one payload. The
483 new KE payload is equivalent to the old KE2 payload.
485 Cleaned up the SKE Start Payload parsing. It now uses the
486 simple buffer unformatting to do the parsing. A lot faster
489 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
490 to the SKE that is used to indicate whether both of the SKE
491 parties should perform authentication. By default only the
492 responder performs authentication. By setting this flag also
493 the initiator must do authentication. By default it is unset
494 since in normal SKE case, client to server connection, only
495 the responder should do authentication. When doing SKE between
496 two clients both should perform authentication. Updated the
497 code and the protocol specs.
499 * A little fix to IDENTIFY command in the server. Search the
500 client first by hash not nickname. Affected file is
503 * Fixed the silc_client_close_connection to support closing
504 the client to client connections wihtout deleting too much
505 data. Affected file lib/silcclient/client.c.
507 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
508 are received if protocol used to be active but is not anymore
509 the application would crash due to NULL pointer dereference.
510 Affected files silcd/server.c and lib/silcclient/client.c.
512 * Added `hash' field to the SilcClientConnection to include
513 the hash function negotiated in the SKE protocol.
515 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
516 to set the channel founder authentication data. A client can
517 claim the founder rights later by providing the authentication
518 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
519 This way the channel founder can regain the channel founder
520 privileges even it is left the channel. This works only on
521 local server and the client must be connected to the same
522 server to be able to regain the founder rights. Updated the
523 protocol specs accordingly.
525 Added support to the CMODE command in the client to set the
526 founder auth data. Read the README to see how to set it.
528 Added support to the CUMODE command to claim the founder
529 rights. Read the README to see how to do it.
531 Added support for the founder authentication to the Channel
532 Entry in the server. Affected file silcd/idlist.h.
534 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
535 server's CMODE command. Affected file silcd/command.c.
537 * Added the following new functions into lib/silccore/silcauth.[ch]:
538 silc_auth_get_method and silc_auth_get_data.
540 * The server now saves the remote hosts public key to the
541 SilcIDListData pointer. Affected file silcd/protocol.c.
543 * The normal server now does not remove the channel entry from
544 the cache if the founder authentication data is set. It used
545 to remove it if the founder was the last one on the channel on
546 the server and left the channel. The auth data is saved and
547 if the channel is re-joined later the old entry is used with
548 the old auth data. Affected files silcd/command_reply.c and
551 * Removed the `pkcs' field from the SilcIDListData structure
552 in the server; it is not used. Affected file silcd/idlist.h.
554 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
556 * Fixed packet processing on slow links. Partial packets were
557 never re-processed because the incoming data buffer was cleared
558 by the application. Application must not directly clear the
559 sock->inbuf, the packet processing routines handle it. Fixed
560 this in client library and in server.
562 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
564 * Fixed the WHOIS and IDENTIFY send reply function to really
565 check whether to send list or just one entry. Affected file
568 * Cleaned up the LEAVE command's channel key distribution. The
569 affected file silcd/command.c.
571 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
572 can enforce the channel mode as well. In that case the ID
573 includes the ID of the server. The code now enforces the
574 mode change if the router have different mode than the server.
576 * The notify client operation with CMODE_CHANGE notify can now
577 return NULL client_entry pointer if the CMODE was not changed
578 by client. Application must check for this.
580 * Added <Server ID> argument to INFO command to support server
581 info fetching by Server ID.
583 * Added silc_server_announce_get_channel_users to get assembled
584 packets of channel users of the specified channel. Affected
585 file silcd/server.[ch].
587 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
588 was freed underneath the ID Cache.
590 * Re-announce clients when the server received CHANNEL_CHANGE
591 notify from the router. Affected file silcd/packet_send.c.
593 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
595 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
596 crashed since it did not handle the fact that there is no cipher
597 called "3" and didn't check the error condition. Now fixed.
599 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
600 flag. It can be used to send message requests.
602 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
604 * Implemented the RESTART command in the client.
606 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
607 notice type messages. Added notice printing to the user
610 * The channel keys are not re-generated if the channel's mode
611 is PRIVKEY, ie private key on the channel exists. Affected
612 files silcd/server.c and silcd/command.c.
614 * Fixed a little bug in channel message delivery when channel
615 private keys are set in the server. Affected file is
618 * Changed the setting on channel->on_channel = TRUE from the
619 silc_client_save_channel_key to the JOIN command reply. The
620 key payload is not received if the private channel key is set.
621 Affected file lib/silcclient/command_reply.c and the
622 lib/silcclient/client_channel.c.
624 * When the CMODE_CHANGE notify is sent and the channel private
625 key mode is removed the channel key must be re-generated in
626 other cells as well. Added this support for the router in the
627 silcd/packet_receive.c.
629 * Added new local command NOTICE to send notice message on
630 channel. Affected file silc/local_command.[ch].
632 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
634 * Added new local command ME to the client. It is used to send
635 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
636 some action. Affected file silc/local_command.[ch].
638 * Changed channel_message and private_message client operations
639 to deliver the message flags to the application. Added also
640 the `flags' arguments to the silc_client_send_channel_message
641 and silc_client_send_private_message functions. Affected file
644 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
646 * Redefined the Private Message Payload to support private message
647 keys and to support the new private message flags. Updated
648 the protocol specs. Flags makes it possible to have for example
651 * Added new type SilcPrivateMessagePayload and defined an API
652 for it in the lib/silcclient/silcprivate.[ch].
654 * Tested private message private keys successfully. Tested the
655 private message key set, unset and list commands with the new
658 * Redefined the Channel Message Payload to include the channel
659 message flags (equal with private message flags) to support
660 for example CTCP style messages.
662 * Defined some of the message (for channel and private message)
663 flags. Updated the protocol specs and added the flags to the
664 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
666 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
668 * Added SilcKeyAgreementStatus type to the key agreement routines
669 to indicate the current status and error if one occured.
670 The status types are defined in the lib/silcclient/silcapi.h.
672 * Added new local command KEY that is used to set and unset private
673 keys for channels, set and unset private keys for private messages
674 with remote clients and to send key agreement requests and
675 negotiate the key agreement protocol with remote client. The
676 key agreement is supported only to negotiate private message keys,
677 it currently cannot be used to negotiate private keys for channels,
678 as it is not convenient for that purpose.
680 * Fixed a minor pending callback setting bug in the function
681 silc_client_get_client_by_id_resolve, now the function works.
682 Affected file lib/silcclient/idlist.c.
684 * Added function silc_net_get_local_port to get local bound
685 port by socket. Added to lib/silcutil/silcnet.[ch].
687 * Added `sockets' and `sockets_count' fields to the SilcClient
688 object. They hold the sockets of the listenning sockets in
689 the client. Listenning sockets may be for example the key
690 agreement server. Affected file lib/silcclient/client.[ch].
691 Added functions the silc_client_add_socket and the
692 silc_client_del_socket. They are exported to the application
695 * Added ~./silc/clientkeys to support other client's public keys.
697 * Renamed verify_server_key client operation to verify_public_key
698 and added one argument to indicate the type of the connection
699 (server, client etc.).
701 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
703 * Added silc_server_connection_auth_request to handle the
704 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
705 silcd/packet_receive.[ch].
707 * Added silc_server_send_connection_auth_request into the
708 silcd/packet_send.c to send the connection auth request packet.
710 * Cleaned up the silcd/protocol.c a bit and fixed some memory
713 * Fixed the public key authentication in responder side in the
714 server. The `auth_data' pointer includes the SilcPublicKey
715 not the path to the public key. Affected file silcd/protocol.c.
717 * Implemented the public key authentication in the initiator side
718 in the server. Affected file silcd/protocol.c.
720 * Removed the [RedirectClient] config section from the server
721 configuration. Is not needed and I don't want to implement it.
723 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
725 * Cleaned up the CMODE command in the server. It now works
726 correctly and supports all the modes defined in the protocol.
727 Affected file is silcd/command.c.
729 * Added `hmac_name' field to the SilcChannelEntry in the server
730 to hold the default HMAC of the channel. It can be set when
731 creating the channel (with JOIN command). Affected files
734 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
735 type to indicate the change of the current cipher and hmac
736 on the channel. Client can safely ignore the <cipher> argument
737 (if it chooses to do so) since the CHANNEL_KEY packet will
738 force the channel key change anyway. The <hmac> argument is
739 important since the client is responsible of setting the new
740 HMAC and the hmac key into use.
742 * Fixed the CMODE command in the client library as well.
744 * Tested CMODE command in router environment successfully.
746 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
748 * Show the version of the remote client (or server) when connecting
749 to the server. It is logged to the log file. Affected file
752 * Fixed the KILLED notify handling in the client library. The
753 client must be removed from all channels when receiving the
756 Also, do not remove the client entry when giving the KILL
757 command but when the KILLED notify is received.
759 * Removed silc_idlist_find_client_by_nickname from the server.
760 Not needed anymore. Affected files silcd/idlist.[ch].
762 * Implemented the CHANNEL_CHANGE notify type handling to the
763 server. Affected file silcd/server.c.
767 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

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

819 * Redefined parts of the SilcChannelEntry in the server to support
820 the new ban and invite lists.
822 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
824 * Redefined the INVITE command. The same command can be used to
825 invite individuals to the channel but also to manage the invite
826 list of the channel (to add to and remove from the invite list).
827 Updated the protocol specs.
829 * Added new command SILC_COMMAND_BAN that can be used to manage
830 the ban list of the channel. Updated the protocol specs.
832 * Removed the channel modes: the SILC_CMODE_BAN and the
833 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
834 in the CMODE command. The equivalent features are now available
835 using INVITE and BAN commands. Updated the protocol specs.
837 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
838 in the network about change in the current ban list. The notify
839 type is not used by the client.
841 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
842 support the invite lists.
844 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
846 * Added new function silc_string_regexify that converts string
847 including wildcard characters into regex string that can
848 be used by the GNU regex library. Added into the file
849 lib/silcutil/silcutil.[ch].
851 Added silc_string_regex_combine to combine to regex strings
852 into one so that they can be used as one regex string by
853 the GNU regex library. Added into the file
854 lib/silcutil/silcutil.[ch].
856 Added silc_string_regex_match to match two strings. It returns
857 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
859 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
861 * Imported GNU regex to the soruce tree into lib/contrib.
862 Fixed some compiler warning from the regex.c.
864 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
866 * Fixed MOTD command in the server to work in router environment.
868 * Fixed the MOTD command in the client library to support
869 the server argument in the command.
871 * Added `nickname_len' argument to the silc_idlist_add_client
872 in the server, as the `nickname' argument may be binary data
875 * Added silc_idlist_get_channels to return all channels from
878 * Implemented LIST command to the server. Affected file is
881 * Implemented the LIST command to the client library and on the
884 * Added [<user count>] argument to the LIST command reply.
885 With private channels the user count is not shown.
887 * Updated TODO and README.
889 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
891 * The client entry's data.registered must be TRUE even with
892 global client entry on global client list. The data.registered
893 is used to check whether the client is anymore in the network,
894 for example with WHOWAS command so it must be valid.
896 * Fixed the WHOWAS command in the server. It now actually works
897 in router environment. Added function into silcd/command_reply.c
898 silc_server_command_reply_whowas_save.
900 * Added silc_idlist_purge function to the silcd/idlist.c
901 to periodically purge the ID Cache.
903 * Fixed INFO command in the server. It works now in router
904 environment. Added <server name> argument to the INFO command
905 reply. Updated the protocol specs.
907 * Fixed minor bug in silc_idcache_purge to not purge if the
908 expire value is zero.
910 * Fixed various bugs in WHOIS and IDENTIFY command handling as
911 they were buggy because of the WHOWAS information.
913 * Fixed local command MSG to handle the async resolving of
914 the remote client properly. It used to fail the first MSG.
915 Affected file silc/local_command.c.
917 * Added `data_len' field to SilcIDCache context.
919 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
921 * Update TODO. Todo in commands in the server.
923 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
925 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
926 used by routers as broadcast packet to inform other routers
927 about the changed user mode.
929 Implemented the notify handling in the server. Affected file is
930 silcd/packet_receive.c. Added the function
931 silc_server_send_notify_umode to the silcd/packet_send.[ch].
933 * Added new generic Channel Payload and deprecated the New Channel
934 Payload. The New Channel Payload is now the generic Channel
937 * Added new argument `mode' to the silc_server_send_new_channel
938 as it is required in the Channel Payload now.
940 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
941 and created a new and real SilChannelPayload to represent the
942 new generic Channel Payload. Implemented the encode/decode
943 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
945 * Added silc_server_get_client_channel_list to return the list
946 of channels the client has joined for WHOIS command reply.
947 Affected file silcd/server.[ch].
949 * Implemented the channel list sending in the WHOIS command reply
950 in server and in the client.
952 Implemented the channel list displaying on the user interface
953 as well. Affected file silc/client_ops.c.
955 * Added silc_channel_payload_parse_list to parse list of Channel
956 Payloads. It returns SilcDList list of SilcChannelPayloads.
957 Client for example can use this function to parse the list of
958 channels it receives in the WHOIS command reply. The caller
959 must free the list by calling silc_channel_payload_list_free.
960 Affected files lib/silccore/silcchannel.[ch].
962 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
964 * Added one new argument <user mode> to the WHOIS command reply
965 to return the mode of the user in SILC. Updated the protocol
968 Implemented it to the server and client.
970 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
972 * Fixed the mode printing on the user interface on joining.
973 Affected file silc/client_ops.c.
975 * Implemented the UMODE command and user modes in general to the
976 client library and to the user interface.
978 * Implemented the UMODE command to the server.
980 * The server now sends UNKNOWN_COMMAND error status if client sends
981 unknown command. Affected file silcd/command.c.
983 * All server commands now handle the command identifier the right
984 way when sending the command reply to the client. The client can
985 use to identify the command replies with the identifier.
987 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
989 * Added silc_server_get_client_route to resolve the route to
990 the client indicated by the client ID. Affected file is
993 * Added silc_server_relay_packet as general function to relay
994 packet to arbitrary destination. This deprecates functions
995 like _send_private_message_key, _relay_notify etc. Affected
996 file is silcd/packet_send.[ch].
998 Removed silc_server_send_key_agreement,
999 silc_server_send_private_message_key and
1000 silc_server_packet_relay_notify functions from the file
1001 silcd/packet_send.[ch].
1005 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1006 server. Affected file silcd/packet_receive.[ch].
1008 * Implemented the KILL command to the client. Implemented the
1009 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1010 Affected files lib/silcclient/command[_reply].c and
1011 lib/silcclient/client_notify.c. Implemented the KILL notify
1012 printing in the user inteface.
1014 * Fixed a lot silc_parse_nick memory leaks from the client
1015 library in the file lib/silcclient/command.c.
1017 * Changed the silc_server_send_notify_on_channels's `sender'
1018 argument from SilcSocketConnection to SilcClientEntry to
1019 check the sender as entry and not as connection object and not
1020 to send to the client provided as argument. The affected file
1021 is silcd/packet_send.[ch].
1023 * The notify packets that are destined directly to the client used
1024 to not to be processed by the server. Now changed that and the
1025 server processes all notify packets. After relaying the packet
1026 to the client the notify packet is processed in the server.
1028 * The silc_server_free_client_data now checks whether there is
1029 pending outgoing traffic for the client and purges the data to
1030 the network before removing the client entry.
1032 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1034 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1035 an client is killed from the SILC Network. Updated the protocol
1038 Added new function silc_server_send_notify_killed to the
1039 silcd/packet_send.[ch].
1041 * Added function silc_server_packet_relay_notify to relay notify
1042 packets that are destined directly to a client. In this case
1043 the server does not process the notify packets but merely relays
1044 it to the client. Affected file silcd/packet_send.[ch].
1046 Added also silc_server_packet_process_relay_notify to check
1047 whereto relay the notify. Affected file is
1048 silcd/packet_receive.[ch].
1050 * Implemented the KILL command to the server.
1054 * Added the backup schema desgined last fall to the protocol
1055 specs for everyone to see. The specification is in the
1056 *-spec-xx.txt draft and the packet type definitions for the
1057 backup routers is in *-pp-xx.txt draft. Thusly, added also
1058 new packet type SILC_PACKET_CELL_ROUTERS.
1060 * A big security problem in the implementation discovered. The
1061 signoff of an client did not cause new channel key generation
1062 which it of course should've done. The channel keys must be
1063 always re-generated when client leaves (or signoffs) the channel.
1064 The silc_server_remove_from_channels funtion now handles
1065 the channel key re-generation.
1067 * Added `sender' argument to the silc_server_send_notify_on_channels
1068 to not to send the client provided as argument. Affected file
1069 silcd/packet_send.[ch].
1071 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1073 * Implemented OPER and SILCOPER commands into the server and
1076 * Added silc_auth_verify and silc_auth_verify_data to verify
1077 the authentication directly from the authentication payload.
1078 It supports verifying both passphrase and public key based
1079 authentication. Affected file lib/silccore/silcauth.[ch].
1081 * Added `hash' field to the SilcIDListData structure. It is the
1082 hash negotiated in the SKE protocol. Affected file is
1085 * Slight redesigning of the SilcAuthPayload handling routines.
1086 Do not send SilcPKCS but SilcPublicKey as argument.
1088 * Implemented the public key authentication support to the
1089 serverconfig. The public key is loaded from the provided path
1090 and saved as authentication data to void * pointer. Thus,
1091 changed the unsigned char *auth_data to void *auth_data;
1093 * Fixed SHUTDOWN command to send the reply before the server
1094 is shutdown. :) Affected file silcd/command.c.
1096 * Fixed fatal bug in CONNECT command. The hostname was invalid
1097 memory and server crashed. Affected file silcd/command.c.
1099 * Fixed fatal bug in CLOSE command. The server_entry became
1100 invalid but was referenced later in the command. Affected file
1103 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1105 * Fixed fatal bug in failure packet handling. Server ignored
1106 the failure and thus crashed when it came.
1110 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1112 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1113 that the command may be executed only once in (about) 2 seconds.
1114 The old SILC_CF_LAG flag is same but allows command bursts up
1115 to five before limiting.
1117 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1118 server code. Various commands now includes the CF_LAG_STRICT
1119 flag to disallow any kind of miss-use of the command.
1121 * Fixed the silc_buffer_unformat to not to allocate any data
1122 if the length of the data is zero. It used to allocate the
1123 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1125 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1127 * Changed the format of AdminConnection configuration section
1128 in the server. Added username of the admin to the format.
1129 Affected files silcd/serverconfig.[ch].
1131 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1132 to return admin configuration data by host, username and/or
1135 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Implemented WHOWAS command to the server. Added the functions:
1139 silc_server_command_whowas_parse,
1140 silc_server_command_whowas_send_reply,
1141 silc_server_command_whowas_from_client and
1142 silc_server_command_whowas_from_server
1144 * Added <Client ID> argument to the WHOWAS command reply. Updated
1145 the protocol specs accordingly.
1147 * Implemented WHOWAS command and command_reply to the client
1150 Implemented the WHOWAS printing on the user interface.
1152 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1154 * Added new argument to the WHOWAS command reply, the real name.
1155 It is an optional argument. Updated the protocol specs.
1157 * Added SilcIDCacheDestructor callback that is registered when
1158 the SilcIDCache is allocated. The callback is called when
1159 an cache entry in the ID Cache expires, or is purged from the
1160 cache. Added into lib/silccore/idcache.[ch].
1162 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1163 to destruct the client entries when the cache entry expires.
1164 Other ID Cache's in server and in the client library ignores
1167 * If the ID Cache entry's `expire' field is zero then the entry
1168 never expires. Added boolean `expire' argument to the
1169 silc_idcache_add function in the lib/silccore/idcache.[ch].
1170 If it is TRUE the default expiry value is used.
1172 * Added silc_server_free_client_data_timeout that is registered
1173 when client disconnects. By default for 5 minutes we preserve
1174 the client entry for history - for WHOWAS command.
1176 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1178 * Added support to the server to enforce that commands are not
1179 executed more than once in 2 seconds. If server receives
1180 commands from client more frequently, timeout is registered
1181 to process the commands. Affected file silcd/command.c.
1182 Added new function silc_server_command_process_timeout.
1184 * Changed NICK_NOTIFY handling in client library to check that
1185 if the client's nickname was changed, so there is no need to
1186 resolve anything from the server.
1188 * Removed error printing from the WHOIS and IDENTIFY commands.
1189 If error occurs then it is ignored silently in the client library.
1190 The application, however, may map the received error to
1191 human readable error string. The application currently maps
1192 the NO_SUCH_NICKNAME error to string.
1194 * Made the command status message public to the application. Moved
1195 them from lib/silcclient/command_reply.c to
1196 lib/silcclient/command_reply.h. The application can map the
1197 received command status to the string with the
1198 silc_client_command_status_message function.
1200 * Added check to the server to check that client's ID is same
1201 as the Source ID in the packet the client sent. They must
1204 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1206 * Added dist-bzip hook to the Makefile.am to make bzip2
1207 compressed distributions.
1209 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1211 * Server now enforces the maximum length for the nickname and
1212 the channel as protocol specification dictates. 128 bytes for
1213 nickname and 256 bytes for channel name.
1215 * Moved the WHOIS printing to the application. The client libary
1216 does not print out the WHOIS information anymore, the application
1217 must do it. Renamed silc_client_command_reply_whois_print to
1218 the silc_client_command_reply_whois_save.
1220 The client's idle time is also sent to the application now, and
1221 the idle is shown on screen.
1223 * Added silc_client_command_reply_identify_save to save the
1224 received IDENTIFY entries.
1226 * Do not check for channel private keys in message sending and
1227 reception if the channel does not have the PRIVKEY mode set.
1228 Affected file lib/silclient/client_channel.c.
1230 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1232 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1233 just surfaced after chaning the JOIN procedure.
1235 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1237 * Added silc_client_get_clients_by_list to get client entries
1238 from Client ID list, that is returned for example by JOIN
1239 and USERS command replies. The application should use this
1240 function for example when JOIN command reply is received to
1241 resolve the clients already on the channel (library does not
1242 do that anymore as USERS command reply is not used in the JOIN
1243 procedure anymore). Affected files lib/silcclient/silcapi.h and
1244 lib/silcclient/idlist.c.
1246 * JOIN command reply and USERS command reply returns now SilcBuffer
1247 pointers instead of unsigned char pointers when returning
1248 the client list and mode list.
1250 * Added <Client ID> argument to the JOIN command reply, mainly
1251 for the server to identify for which client the command was
1252 originally sent. Updated protocol specs accordingly.
1254 * Added SilcDlist private_key pointer to the SilcChannelEntry
1255 in the client to support the channel private keys. Affected
1256 file is lib/silcclient/idlist.h.
1258 * Added SilcChannelPrivateKey argument to the function
1259 silc_client_send_channel_message so that application can choose
1260 to use specific private ke if it wants to. If it is not provided,
1261 the normal channel key is used, unless private keys are set.
1262 In this case the first (key that was added first) is used
1263 as the encryption key.
1265 * Implemented the support for channel private key handling.
1266 Implemented the following functions:
1268 silc_client_add_channel_private_key,
1269 silc_client_del_channel_private_keys,
1270 silc_client_del_channel_private_key,
1271 silc_client_list_channel_private_keys and
1272 silc_client_free_channel_private_keys
1274 Affected file lib/silcclient/client_channel.c.
1276 * Added the support for the private keys in the channel message
1277 sending and encryption and in the message reception and
1278 decryption. Affected funtions are
1279 silc_client_send_channel_message and silc_client_channel_message.
1281 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1283 * Added SKE's key verify callback to the client library's
1284 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1286 * Removed the statement that server (or router) must send USERS
1287 command reply when joining to the channel so that the client
1288 knows who are on the channel. Instead, the client list and
1289 client's mode list is now sent in the JOIN command reply to the
1290 client who joined channel. This is better solution.
1292 * Added function silc_server_get_users_on_channel and function
1293 silc_server_save_users_on_channel to the silcd/server.[ch].
1295 * Removed function silc_server_command_send_users from the
1298 * Do not show topic on the client library anymore. The topic is
1299 sent in the command reply notify to the application and the
1300 application must show the topic now.
1302 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1304 * Added client searching by nickname hash into the IDENTIFY and
1305 WHOIS commands in the server as they were clearly missing from
1306 them. Affected file is silcd/command.c.
1308 * Fixed a bug in private message receiving in the client library.
1309 The remote ID was freed and it wasn't supposed, now it is
1312 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1314 * Minor fix to the channel payload; allocate the data area, as it
1315 needs to be of specific length.
1317 * If the key agreement port is zero then the operating
1318 system will define the bound port. Affected files are
1319 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1321 * Added new function silc_channel_payload_decrypt into the file
1322 lib/silccore/silcchannel.[ch].
1324 * Moved the channel message etc, check from silc_packet_decrypt
1325 to applications. The library calls now a generic
1326 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1327 when the packet is either normal or special. This was done to
1328 allow more wide range of checking that was not allowed when
1329 the code was in library. Now applications can do virtually any
1330 checks to the packet and return to the library the decision how
1331 the packet should be processed. Affected files are
1332 lib/silccore/silcpacket.[ch].
1334 Added silc_server_packet_decrypt_check to the server and
1335 silc_client_packet_decrypt_check to the client library.
1337 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1338 to send with specified source and destination information.
1340 * Channel message delivery between routers was broken after the
1341 channel key distribution was fixed earlier. The channel key
1342 was used be to distributed to other routers as well which is not
1343 allowed by the protocol. Now this is fixed and channel keys
1344 really are cell specific and the channel message delivery between
1345 routers comply with the protocol specification.
1347 * Fixed various commands in server to check also the global list
1348 for the channel entry and not just the local list. The affected
1349 file silcd/command.c.
1351 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1353 * Added assert()s to buffer formatting and unformatting routines
1354 to assert (if --enable-debug) when error occurs. Affected
1355 file: lib/silcutil/silcbuffmt.c.
1357 * Changed to auto-reconnect to check whether the remote host is
1358 router and register the re-connect timeout if it is. It used
1359 to check that whether we are normal server, but router must do
1360 auto-reconnect with another router as well. Affected file
1363 * Removed the [<key len>] option from CMODE command as the cipher
1364 name decides the key length, nowadays. See the defined ciphers
1365 from the protocol specification.
1367 * Added [<hmac>] option to the CMODE command to define the HMAC
1368 for the channel. Added SILC_CMODE_HMAC channel mode.
1370 * Added [<hmac>] option for the JOIN command so that user can
1371 select which HMAC is used to compute the MACs of the channel
1374 * Added Hmac field to the Channel Message Payload. The integrity
1375 of plaintext channel messages are now protected by computing
1376 MAC of the message and attaching the MAC to the payload. The
1377 MAC is encrypted. Now, it is clear that this causes some
1378 overhead to the size of the packet but rationale for this is that
1379 now the receiver can verify whether the channel message decrypted
1380 correctly and also when private keys are set for the channel the
1381 receiver can decrypt the packet with several keys and check from
1382 the MAC which key decrypted the message correctly.
1384 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1385 lib/silccrypt/silccipher.[ch].
1387 * Added silc_hash_len to return the digest length into the
1388 lib/silcrypt/silchash.[ch].
1390 * Rewrote parts of Silc Channel Payload interface in the
1391 lib/silccore/silcchannel.[ch]. The encode function now also
1392 encrypts the packet and parse function decrypts it.
1394 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1396 * Fixed a minor formatting bug in the SKE's key material processing.
1397 It actually might have processed the keys wrong way resulting
1400 * Redefined the mandatory HMAC algorithms and added new algorithms.
1401 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1402 and hmac-md5 truncated to 96 bits. The mandatory is now
1403 hmac-sha1-96. Rest are optional (including the one that used
1404 to be mandatory). Rationale for this is that the truncated HMAC
1405 length is sufficient from security point of view and can actually
1406 make the attack against the HMAC harder. Also, the truncated
1407 HMAC causes less overhead to the packets. See the RFC2104 for
1410 * Added new [hmac] configuration section. The SKE used to use
1411 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1412 is of course wrong. The official names that must be proposed in
1413 the SKE are the ones defined in the protocol specification
1414 (hmac-sha1-96 for example). The user can configure any hmac
1415 using any hash function configured in the [hash] section. At
1416 least, the mandatory must be configured.
1418 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1420 * Added HMAC list to the SKE proposal list. It has now both
1421 hash algorithm list and HMAC list. This makes the protocol
1422 incompatible with previous versions. The SKE now seems to work
1423 the way it is supposed to work, for the first time actually.
1425 * Defined plain Hash algorithms to the protocol specification.
1428 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1430 * Implemented support for key agreement packets into the server.
1431 Added functions silc_server_key_agreement and
1432 silc_server_send_key_agreement. Other than these functions,
1433 server has nothing to do with this packet.
1435 * Added support for private message key packets into the server.
1436 Added functions silc_server_private_message_key and
1437 silc_server_send_private_message_key.
1441 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1442 called in the protocol's final callback instead in the END
1443 protocol state. This makes a little more sense and in the same
1444 time in client we can use the same protocol routines for normal
1445 key exchange and to key agreement packet handling as well.
1447 * Added to both client's and server's KE protocol context the
1448 SilcSKEKeyMaterial pointer to save the key material. We will
1449 bring the key material to the protocol's final callback by doing
1450 this. The final callback must free the key material.
1452 * Added SKE's packet_send callback into client's KE protocol
1453 context so that the caller can choose what packet sending function
1454 is used. This way we can use different packet sending when
1455 doing normal SKE when doing key agreement packet handling (in
1456 the key agreement packet handling we do not want to encrypt
1459 * Implemented the responder side of the key agreement routines
1460 in the client. The client can now bind to specified port and
1461 accept incoming key negotiation. The key material is passed
1462 to the application after the protocol is over.
1464 * Implemented the processing of incoming Key Agreement packet
1465 in the client. Added function silc_client_key_agreement to
1468 * Implemented the intiator side of the key agreement routines
1469 in the client. The client can now initiate key agreement with
1470 another remote client. The key material is passed to the
1471 application after the protocol is over.
1473 * Created client_keyagr.c to include all the key agreement
1476 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1477 SILC_TASK_CALLBACK except that it is not static.
1479 * Created client_notify.c and moved the Notify packet handling
1480 from the client.[ch] into that file.
1482 * Created client_prvmsg.c and moved all private message and
1483 private message key routines from the client.[ch] into that file.
1485 * Create client_channel.c and moved all channel message and
1486 channel private key routines from the client.[ch] into that file.
1488 * Changed silc_client_get_client_by_id_resolve to resolve with
1489 WHOIS command instead of IDENTIFY command, in the file
1490 lib/silclient/idlist.c.
1492 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1494 * Implemented the SKE's responder side to the Client library.
1496 * When FAILURE is received to the protocol do not trust it
1497 blindly. Register a timeout to wait whether the remote closes
1498 the connection as it should do it, only after that process the
1499 actual failure. This was changed to both client and server.
1501 * Added client_internal.h to include some of the structures
1502 there instead of client.h in lib/silcclient/.
1504 * Added function silc_task_unregister_by_callback to unregister
1505 timeouts by the callback function.
1507 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1509 * Some "Incomplete WHOIS info" errors has been appearing on the
1510 log files. Took away the entry->userinfo check from WHOIS
1511 reply sending. The entry->userinfo is now " " if client did not
1512 provide one. I thought this was fixed earlier but something
1513 is wrong still. Let's see if the error still appears.
1515 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1517 * Fixed a minor bug in the login when the channel key is
1518 re-generated in the server. It used to generate the key in
1519 wrong order and thus caused problems in the channel traffic.
1521 * Fixed a minor bug in channel key distsribution after
1522 KICK command. The key was not sent to the router even though
1525 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1527 * Added silc_ske_process_key_material_data as generic routine
1528 to process any key material as the SILC protocol dictates. The
1529 function is used by the actual SKE library but can be used by
1530 applications as well. This relates to the private message keys
1531 and the channel private keys since they must be processed the
1532 same way the normal SILC session keys. The protocol dictates
1533 this. Affected files: lib/silcske/silcske.[ch].
1535 Added also silc_ske_free_key_material to free the
1536 SilcSKEKeyMaterial structure.
1538 * Defined silc_cipher_set_key function to set the key for
1539 cipher without using the object's method function. The affected
1540 files: lib/silccrypt/silccipher.[ch].
1542 * Implemented silc silc_client_add_private_message_key,
1543 silc_client_add_private_message_key_ske,
1544 silc_client_del_private_message_key,
1545 silc_client_list_private_message_keys and
1546 silc_client_free_private_message_keys functions in the
1549 Added functions silc_client_send_private_message_key to send
1550 the Private Message Key payload and silc_client_private_message_key
1551 to handle incoming Private Message Key payload.
1553 * Added Cipher field to the Private Message Key payload to set
1554 the cipher to be used. If ignored, the default cipher defined
1555 in the SILC protocol (aes-256-cbc) is used.
1557 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1559 * Removed lib/silcclient/ops.h file.
1561 Redefined parts of the SILC Client Library API. Created new
1562 file silcapi.h that deprecates the ops.h file and defines the
1563 published Client Library API. Defined also private message key
1564 API and channel private key API into the file.
1566 This is the file that the application must include from the
1567 SILC Client Library. Other files need not be included by
1568 the application anymore.
1570 * Added new key_agreement client operation callback and also
1571 defined the Key Agreement library API for the application.
1573 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1575 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1576 is used by clients to request key negotiation between another
1577 client in the SILC network. If the negotiation is started it
1578 is performed using the SKE protocol. The result of the
1579 negotiation, the secret key material, can be used for example
1580 as private message key.
1582 Implemented the Key Agreement payload into the files
1583 lib/silccore/silauth.[ch].
1585 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1587 * Redefined ciphers for the SILC protocol. Added some new ciphers
1588 and defined the key lengths for the algorithms. Changed the
1589 code accordingly. The default key length is now 256 bits.
1591 * Fixed SKE key distribution function silc_ske_process_key_material
1592 when the key length is more than 128 bits. The default key
1593 length in SILC is now 256 bits.
1595 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1596 to indicate unsupported algorithm.
1598 * Renamed rijndael.c to aes.c and all functions as well.
1600 * Fixed a long standing channel key setting bug in client library.
1601 Weird that it has never surfaced before.
1603 * Fixed bug in channel deletion. If the entire channel is removed
1604 then it must also delete the references of the channel entry
1605 from the client's channel list as the client's channel entry and
1606 the channel's client entry share same memory.
1608 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1610 * Implemented CONNECT and SHUTDOWN commands in the client.
1612 * Implemented CLOSE command to the client.
1614 * Added the function silc_idlist_find_server_by_name into the
1615 files silcd/idlist.[ch].
1617 Added the function silc_idlist_find_server_by_conn into the
1618 files silcd/idlist.[ch].
1620 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1622 * DIE command was renamed to SHUTDOWN. Updated the both code
1625 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1626 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1628 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1631 * Added function silc_server_create_connection function to create
1632 connection to remote router. My server implementation actually
1633 does not allow router to connect to normal server (it expects
1634 that normal server always initiates the connection to the router)
1635 so the CONNECT command is only good for connecting to another
1638 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1640 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1641 or some other client was kicked from the channel.
1643 Implemented the handling of the notify type to both client
1646 Implemented silc_server_send_notify_kicked to send the KICKED
1647 notify. It is used to send it to the server's primary router.
1649 * Implemented the KICK command into server and client.
1651 * Added `query' argument to the silc_idlist_get_client function
1652 to indicate whether to query the client from server or not if
1655 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1656 to indicate that the client is not channel founder.
1660 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1662 * Removed the rng context from SilcPacketContext structure and
1663 changed that the packet routine uses the Global RNG API.
1665 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1667 * Added support for quit message that client can "leave" on the
1668 channel when it quits the SILC. It is ditributed inside the
1669 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1671 Added silc_server_free_client_data that will take the
1672 signoff message as argument.
1674 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1676 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1678 * Updated parts of the protocol specification to keep it up
1681 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1683 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1684 payloads in one packet.
1686 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1687 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1688 use now the new List flag.
1690 * Also deprecated the following packet types: REPLACE_ID,
1691 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1693 * Added list support for Notify packet in server.
1695 * Added silc_server_send_notify_channel_change to send the
1696 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1697 the silc_server_send_replace_id.
1699 * Added silc_server_send_notify_nick_change to send the
1700 NICK_CHANGE notify type. Deprecates the function
1701 silc_server_send_replace_id.
1703 * Added silc_server_send_notify_join to send the JOIN notify type.
1704 Deprecates the function silc_server_send_new_channel_user.
1706 * Added silc_server_send_notify_leave to send LEAVE notify type.
1707 Deprecates the function silc_server_send_remove_channel_user.
1709 * Added silc_server_send_notify_cmode and
1710 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1711 types. Deprecates the silc_server_send_set_mode function.
1713 * Added SERVER_SIGNOFF notify type to indicate that server has
1714 quit. This means that all clients on the channel from that
1715 server will drop. This can be also used when netsplit happens.
1717 Deprecated REMOVE_ID packet type since it is not needed anymore
1720 Added silc_server_send_notify_server_signoff to send the
1721 SERVER_SIGNOFF notify type. Deprecates the function
1722 silc_server_send_remove_id.
1724 Added also silc_server_send_notify_signoff to send the
1725 SIGNOFF notify type.
1727 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1728 SILC protocol from this day on. Changed the protocol
1729 specification as well.
1731 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1732 notify type. It is used between routers to notify about
1733 topic changes on a channel.
1735 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1738 * Partly updated the protocol specification to comply with the
1739 changes now made. It is still though a bit outdated.
1741 * The JOIN notify type now takes one extra argument <Channel ID>.
1742 The packet used to be destined to the channel but now the
1743 JOIN type may be sent as list thus it is impossible to
1744 destine it to any specific channel. By adding this argument
1745 it is again possible.
1747 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1749 * Added CREDITS file. The CHANGES and CREDITS file will appear
1750 in the distribution as well.
1752 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1754 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1755 types in the server's silcd/packet_receive.c.
1757 * Implemented CMODE and CUMODE to work in router environment.
1759 * Fixed minor encoding and decoding buglet from the
1760 lib/silccore/silcmode.c.
1762 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1765 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1767 * Changed all SilcConfigServer* and silc_config_server* to
1768 SilcServerConfig* and silc_server_config*, respectively.
1771 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1773 * Associated the ID (client or server ID) to the Authentication
1774 Payload to avoid any possibility of forging. Updated the
1775 protocol specification and the code accordingly.
1777 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1779 * The RSA key length is now save to the RsaKey context in the
1780 key generation process in lib/silccrypt/rsa.c. The key length
1781 is now used to figure out the maximum size of the block allowed
1782 to be encrypted/signed.
1784 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1785 is equivalent to the silc_mp_mp2bin but does not allocate any
1788 * Changed silc_mp_mp2bin API to take length argument. If it is
1789 non-zero then the buffer is allocated that large. If zero, then
1790 the size is approximated using silc_mp_sizeinbase, which however
1793 * Created Global RNG API which is global RNG that application can
1794 initialize. After initializing, any routine anywhere in the
1795 code (including library) can use RNG without allocating a new
1796 RNG object. This was done to allow this sort of use of the
1797 RNG in code that has no chance to allocate RNG object. All
1798 applications currently allocate this and many routines in the
1799 library use this. Affected file lib/silccrypt/silcrng.[ch].
1801 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1802 it to use the Global RNG API.
1804 * Defined Authentication Payload into protocol specification that
1805 is used during SILC session to authenticate entities. It is
1806 used for example by client to authenticate itself to the server
1807 to obtain server operator privileges.
1809 Implemented this payload into the lib/silccore/silcauth.[ch].
1810 Implemented also routines for public key based authentication
1811 as the new protocol specification dictates.
1813 Moved definitions of different authentication methods from
1814 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1816 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1817 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1818 silc_pkcs_verify_with_hash functions into the file
1819 lib/silccrypt/silcpkcs.[ch].
1821 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1823 * The client entry's userinfo pointer must be always valid.
1824 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1825 will fail since it requires the userinfo. Now, the userinfo
1826 is allocated as "" if actual userinfo does not exist. Actually,
1827 it must exist and it is totally Ok to drop client connections
1828 that does not announce the userinfo. However, we will make
1829 this workaround for now.
1831 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1832 to return the remote port by socket.
1834 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1836 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1837 SILC_SERVER_PENDING_EXEC and added an new macro
1838 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1839 data or when error occurs while processing the pending command.
1841 Added new argument `destructor' into silc_server_command_pending
1842 and to the SilcServerCommandPending object. This destructor is
1843 now called after calling the pending callback or if error occurs
1844 immediately. If error occurs the actual pending callback won't
1845 be called at all - only the destructor. The destructor may be
1846 NULL if destructor is not needed.
1848 All this applies for client library code as well. Similar
1849 changes were made there as well for the pending commands.
1851 In the client, the application must now allocate the
1852 SilcClientCommandContext with the silc_client_command_alloc
1855 * Added reference counter to the SilcServerCommandContext. Added
1856 function silc_server_command_alloc and silc_server_command_dup
1859 Same type of functions added to the client library for the same
1862 * Removed the cmd_ident from IDListData away since it is now
1863 global for all connections. It is the command identifier used
1864 in command sending and with pending commands. The affected file
1867 * Added reference counter to the SilcSocketConnection objecet to
1868 indicate the usage count of the object. The object won't be
1869 freed untill the reference counter hits zero. Currently only
1870 server uses this, and client ignores it. The client must be
1871 set to use this too later. The affected files are
1872 lib/silccore/silcsockconn.[ch]. Added also the function
1873 silc_socket_dup to increase the reference counter.
1875 This was mainly added because it is possible that the socket
1876 is removed underneath of pending command or other async
1877 operation. Now it won't be free'd and proper DISCONNECTING
1878 flags, etc. can be set to avoid sending data to connection that
1879 is not valid anymore.
1881 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1882 the connection. After that it sets SILC_SET_DISCONNECTED.
1883 It is, however, possible that the socket data is not still freed.
1884 The silc_server_packet_process now checks that data is not
1885 read or written to connection that is DISCONNECTED. The socket
1886 get's freed when the reference counter hits zero.
1888 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1890 * Changed the client operation API: channel_message operation's
1891 `sender' is now the client entry of the sender, not the nickname
1892 and the `channel' is the channel entry, not the channel name.
1894 In the private_message operation the `sender' is now also the
1895 client entry of the sender not the nickname.
1897 Affected file is lib/silcclient/ops.h and all applications
1898 using the client operations.
1900 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1902 * Moved the calling of ops->connect() from connect_to_server_final
1903 into receive_new_id functin since that is the point when the
1904 client is actually allowed to send traffic to network. The
1905 affected file is lib/silcclient/client.c.
1907 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1909 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1910 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1911 (if needs broadcasting) instead of broadcasting the packets one
1912 by one which would make a burst in the network traffic.
1914 * Added `broadcast' argument to the functions in silcd/server.[ch]
1915 silc_server_create_new_channel[_with_id] to indicate whether
1916 to send New Channel packet to primary router.
1918 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1920 * Added new function into the silcd/server.[ch] files:
1921 silc_server_create_new_channel_with_id to create new channel with
1922 already existing Channel ID.
1924 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1925 lib/silccore/silcpacket.h. This packet is used t send list of
1926 Set Mode payloads inside one packet. Server uses this to set
1927 the modes for the channels and clients on those channels, that it
1928 announced to the router when it connected to it. The protocol
1929 specification has been updated accordingly.
1931 * The silc_server_new_channel did not handle the packet coming
1932 from normal server as it normally does not send that. However,
1933 when it announces its channels it does send it. Implemented
1934 the support for that.
1936 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1937 into the file lib/silccore/id.h.
1939 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1941 * Fixed memory leaks in the functions silc_idlist_del_client,
1942 silc_idlist_del_channel and silc_idlist_del_server in the file
1943 silcd/idlist.c. All of those leaked like a sieve.
1945 * Fixed some small memory leaks in the client's function
1946 silc_client_notify_by_server.
1948 * Added functions into silcd/server.c: silc_server_announce_clients,
1949 silc_server_announce_channels and silc_server_announce_server.
1950 These functions are used by normal and router server to announce
1951 to its primary router about clients, channels and servers (when
1952 router) that we own. This is done after we've connected to the
1955 These functions effectively implements the following packet types:
1956 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1957 and SILC_PACKET_NEW_ID_LIST.
1959 * Added new functions into the silcd/packet_receive.[ch]:
1960 silc_server_new_id_list, silc_server_new_channel_list and
1961 silc_server_new_channel_user_list to handle the incoming
1962 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1964 * Added support of changing Channel ID in the function
1965 silc_server_replace_id. If the server that announces a channel
1966 to the router already exists in the router (with same name but
1967 with different Channel ID), router is responsible to send
1968 Replace ID packet to the server and force the server to change
1969 the Channel ID to the one router has.
1971 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1972 client that the Channel ID has been changed by the router. The
1973 normal server sends this to the client. Client must start using
1974 the new Channel ID as the channel's ID.
1976 Implemented handling of this new type into lib/silcclient/client.c
1977 into the function silc_client_notify_by_server.
1979 * Added new function silc_idlist_replace_channel_id into the files
1980 silcd/idlist.[ch] to replace the Channel ID.
1982 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1984 * Call silc_server_command_identify_check always when processing
1985 the IDENTIFY command in silcd/command.c
1987 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1989 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
1990 send keepalive packets. The packet can be sent by clients,
1991 servers and routers.
1993 Added function silc_socket_set_heartbeat into the file
1994 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
1995 If not set, the heartbeat is not performed. The actual
1996 heartbeat is implemented in the low level socket connection
1997 library. However, application is responsible of actually
2000 Added silc_server_send_heartbeat to send the actual heartbeat
2001 packet into silcd/packet_send.[ch]. Server now performs
2002 keepalive with all connections.
2004 * Added silc_task_get_first function into lib/silcutil/silctask.c
2005 to return the timeout task with shortest timeout. There was a bug
2006 in task unregistration that caused problems. TODO has been
2007 updated to include that task system must be rewritten.
2009 * The client library will now resolve the client information when
2010 receiving JOIN notify from server for client that we know but
2011 have incomplete information.
2013 * Rewrote parts of silc_server_remove_from_channels and
2014 silc_server_remove_from_one_channel as they did not remove the
2015 channel in some circumstances even though they should've.
2017 * Encryption problem encountered in server:
2019 The LEAVE command used to send the Channel Key packet to the
2020 router immediately after generating it. However, the code
2021 had earlier sent Remove Channel user packet but not immediately,
2022 ie. it was put to queue. The order of packets in the router
2023 was that Channel Key packet was first and Remove Channel User
2024 packet was second, even though they were encrypted in the
2025 reverse order. For this reason, MAC check failed. Now, this
2026 is fixed by not sending the Channel Key packet immediately but
2027 putting it to queue. However, this is more fundamental problem:
2028 packets that are in queue should actually not be encrypted
2029 because packets that are sent immediately gets encrypted
2030 actually with wrong IV (and thus MAC check fails). So, packets
2031 that are in queue should be encrypted when they are sent to
2032 the wire and not when they put to the queue.
2034 However, the problem is that the current system has not been
2035 designed to work that way. Instead, the packet is encrypted
2036 as soon as possible and left to the queue. The queue is then
2037 just purged into wire. There won't be any fixes for this
2038 any time soon. So, the current semantic for packet sending
2041 o If you send packet to remote host and do not force the send
2042 (the packet will be in queue) then all subsequent packets to the
2043 same remote host must also be put to the queue. Only after the
2044 queue has been purged is it safe again to force the packet
2047 o If you send all packets immediately then it safe to send
2048 any of subsequent packets through the queue, however, after
2049 the first packet is put to queue then any subsequent packets
2050 must also be put to the queue.
2052 Follow these rules and everything works fine.
2054 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2056 * Added new function silc_server_remove_clients_by_server to
2057 remove all client entries from ID list when the server connection
2058 is lost. In this case it is also important to invalidate all
2059 client entires as they hold the invalid server entry. This
2060 fixes fatal bug when server has lost connection and will reconnect
2063 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2065 * Made some sanity checks to silc_server_daemonise like to check
2066 whether the requested user and group actually exists.
2068 * Added sanity check to SKE's silc_ske_responder_finish to check
2069 that the public and private key actually is valid.
2071 * Invalidate the client's nickname when receiving Replace ID
2072 packet and the Client ID is being replaced. This means that the
2073 server will query the nickname if someone needs it (client)
2076 * Sort the ID Cache in client library when the ID Cache data
2077 has changed (needs sorting).
2079 * Do not allow for SILC client to create several connections to
2080 several servers. The client does not support windows right now
2081 and generating multiple connections causes weird behaviour.
2083 Irssi-silc client does support windows and can handle several
2084 connections without problems, see: www.irssi.org and SILC plugin.
2086 * Fixed some places where client was added to the IDList. The
2087 rule of thumb is following (in order to get everything right):
2088 If the client is directly connected local client then the
2089 `connection' argument must be set and `router' argument must be
2090 NULL to silc_idlist_add_client function. If the client is not
2091 directly connected client then the `router' argument must
2092 bet set and the `connection' argument must be NULL to the
2093 silc_idlist_add_client function.
2095 * The funtion silc_server_packet_send_local_channel actually did
2096 not check whether the client was locally connected or not. It
2097 does that now. Fixed a bug related to LEAVE command.
2099 * Fixed Remove Channel User payload parsing bug in server's
2100 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2102 * The server's silc_server_save_channel_key now checks also the
2103 global ID list for the channel as it might not be in the local
2104 list. Fixed a bug related to LEAVE command.
2106 * Is this the end of the [<unknown>] buglet that has been lurking
2107 around for a long time? A little for loop fix in server's
2108 silc_server_command_whois_parse that is used by both IDENTIFY
2109 and WHOIS command. At least, this was a clear bug and a cause
2110 of one type of [<unknown>] buglet.
2112 * WHOIS and IDENTIFY commands call the function
2113 silc_server_command_[whois/identify]_check function even if
2114 we are not router server.
2116 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2118 * Added --with-gmp configuration option. If set the GMP
2119 is always compiled in the SILC source tree. If not set then
2120 it is checked whether the system has the GMP3 installed. If
2121 it has then the GMP won't be compiled (the system's headers
2122 and library is used), if it doesn't have it then the GMP is
2123 compiled in the SILC source tree.
2125 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2127 * Changed RSA private exponent generation to what PKCS #1
2128 suggests. We try to find the smallest possible d by doing
2129 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2130 not security fix but optimization.
2132 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2134 * Added new config entry [Identity] to fork the server and run
2135 it as specific user and group. A patch from Bostik.
2137 * Imported Dotconf configuration library into lib/dotconf.
2138 This will be used to create the SILC configuration files later.
2139 It will appear in the distsribution after this commit.
2141 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2143 * A big code auditing weekend happening. Auditing code for
2144 obvious mistakes, bugs and errors. Also, removing any code
2147 Removed files for being obsolete:
2149 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2150 inline in the file lib/silcutil/silcbuffer.h)
2152 o lib/silcutil/silcbufutil.c (the header has inline versions)
2154 Changed code to fix possible error conditions:
2156 o The buffer formatting routines now check that the destination
2157 buffer really has enough space to add the data. This applies for
2158 both buffer formatting and unformatting
2159 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2160 unformatting was changed to accomodate following rules:
2161 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2162 sent to the function while XXX_*STRING will not allocate or copy
2163 the data into the buffer. Instead it sets the pointer from the
2164 buffer into the pointer sent as argument (XXX_*STRING used to
2165 require that the pointer must be allocated already). This change
2166 makes this whole thing a bit more consistent and more optimized
2167 (note that the data returned in the unformatting with XXX_*STRING
2168 must not be freed now). The routines return now -1 on error.
2170 o Tried to find all code that use buffer_format and buffer_unformat
2171 and added return value checking to prevent formatting and
2172 especially unformatting errors and possible subsequent fatal
2175 o Changed ske->x and ske->KEY to mallocated pointers in
2176 lib/silcske/silcske.h. Fixed possible data and memory leak.
2178 o Added return value checking to all *_parse* functions. Fixed
2179 many memory leaks as well.
2181 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2182 so that buffer overflows would not happen. All code now also
2183 checks the return value as it can fail.
2185 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2187 * Added reconnection support to server if the normal server looses
2188 its connection to the router (for example if router is rebooted).
2189 The server performs normal reconnection strategy implemented
2190 to the server. Affected file silcd/server.c.
2192 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2194 * Added new packet type SILC_PACKET_SET_MODE that is used to
2195 distribute the information about changed modes (for clients,
2196 channels and clients channel modes) to all routers in the
2197 network. Updated the protocol specification accordingly.
2199 Added functions into silcd/packet_send.c and
2200 silcd/packet_receive.c: silc_server_send_set_mode,
2201 silc_server_set_mode.
2203 Added new files silcmode.[ch] into lib/silccore that implements
2204 the encoding and decoding of Set Mode Payload. Added new type
2205 SilcSetModePayload. Moved the definitions of different modes
2206 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2208 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2210 * Oops, a little mistake in server's connection authentication
2211 protocol. The protocol is not ended with FAILURE but with
2212 SUCCESS if the authentication is Ok. :) Affected file is
2215 * Implemented NICK_CHANGE notify handling in server in the file
2216 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2217 the local clients on the channel. After the changing nickname
2218 in router environment snhould work and the [<unknown>] nickname
2219 should appear no more.
2221 The silc_server_replace_id function that receives the Replace ID
2222 payload now sends the NICK_CHANGE notify type also in the file
2223 silcd/packet_receive.c
2225 * Changed WHOIS and IDENTIFY command to support the maximum amount
2226 of arguments defined in protocol specs (3328 arguments). This
2227 fixed a bug that caused problems when there were more than three
2230 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2232 * Added extra parameter, command identifier, to the
2233 silc_client_send_command so that explicit command identifier
2236 Changed that ID list routines uses specific command identifier
2237 when sending WHOIS/IDENTIFY requests to the server so that they
2238 can be identified when the reply comes back.
2240 Affected files lib/silcclient/command.[ch],
2241 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2243 * Added `sender' argument to silc_server_packet_send_to_channel
2244 to indicaet the sender who originally sent the packet to us
2245 that we are now re-sending. Ignored if NULL. Affected file
2246 silcd/packet_send.[ch].
2248 * Added some server statistics support in silcd/server_internal.h
2249 SilcServerStatistics structure and around the server code. Also
2250 send some nice statistics information when client is connecting
2253 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2255 * Fixed channel ID decoding in server's JOIN command reply in
2256 silcd/command_reply.c
2258 * Fixed braodcasting of replace ID payload to not to send it if
2259 we are standalone server in silcd/packet_receive.c.
2261 * Fixed all channel message sending routines to not to send
2262 packets to clients that has router set, since they are routed
2263 separately in the same function earlier. Affects file
2264 silcd/packet_send.c and all channel packet sending functions.
2266 * In USERS reply, res_argv[i] are not allocated, the table
2267 is allocated. Thus changed that free the table, not its
2270 * In server's whois_check and identify_check if the client is
2271 locally connected do not send any WHOIS commands - they are not
2274 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2276 * Fixed some minor bugs in client when sending WHOIS command. The
2277 arguments was in wrong order.
2279 * Removed statis function add_to_channel from server in
2280 silcd/command.c that was previously used with the joining but
2283 * Tested USERS command in router environment successfully with two
2284 routers, two servers and two clients.
2286 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2288 * Reorganized the USERS command and command reply in client library
2289 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2290 When the command is given by user we register a pending command
2291 callback that will reprocess the command after the reply has been
2292 received from the server. When reprocessing the packet we then
2293 display the information. Thus, the USERS information is displayed
2294 now in the command callback instead of in the command reply
2295 callback. The processing of the command is same as previously
2296 when server has sent the command reply in the JOINing process.
2298 * Added to USERS command in silcd/command_reply.c to join the client,
2299 we didn't use to know about, to the channel after we've created
2300 a client entry for it. Also, for clienet we did know already still
2301 check whether it is on the channel or not and add it if not.
2303 * Removed silc_server_command_join_notify as the function and its
2306 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2308 * Changed the client's pending command handling to the same as the
2309 server's pending command handling. It is also now possible to
2310 execute command reply functions from other command reply
2311 function as the function callbacks for commands and command
2312 replies are one and same. The pending commands are not static
2313 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2314 in client connection context. Thus, pending commands are server
2315 connection specific as it is convenient.
2317 Changed the function silc_client_command_pending and
2318 silc_client_command_pending_del and added new function
2319 silc_client_command_pending_check. Removed the
2320 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2323 * Added cmd_ident, current command identifier, to the client
2324 connection context in lib/silcclient/client.h to keep track on
2325 command identifiers used in command sending. Client's command reply
2326 function handling now supports the mandatory command identifiers.
2328 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2329 funtions in client to fully support pending command callbacks.
2331 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2332 as one of the arguments to the application in the command reply
2335 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2336 before first releasing SILC but came back. Now it is removed again
2337 and should come back nomore. The FORWARDED flag was used only
2338 by the JOINing procedure by forwarding the command packet to router.
2339 Now, the JOINing procedure has been changed to more generic (due
2340 to various router environment issues) and FORWARDED is not needed
2341 anymore for anything. The protocol specification is yet to be
2344 Now, removed silc_server_packet_forward from server and the flag
2345 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2347 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2349 * Renamed NAMES command to USERS command. The NAMES was named that
2350 due to historical reasons. Now it is renamed. Also, rewrote
2351 parts of the USERS command. The nickname list is not sent anymore
2352 by the server. Only Client ID and mode lists are sent in the USERS
2353 command. Changed this also to the protocol specification.
2355 The client now resolves the names and stuff after it receives
2356 the USERS list from the server when joining to the channel.
2358 * WHOIS and IDENTIFY commands has been changed to support multiple
2359 Client ID's per command. One can now search for multiple users
2360 in the network by sending only one WHOIS or IDENTIFY command.
2361 Changed the code and the protocol specifications.
2363 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2364 uses silc_server_command_whois_parse to parse the request. */
2366 * If normal server, do not parse the WHOIS and IDENTIFY requests
2367 before sending it to the router. Saves some time.
2369 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2371 * Fixed JOIN command on client library. Wrong number of arguments
2372 used to crash the client.
2374 * Added silc_server_channel_has_global function to check whether
2375 channel has global users or not.
2377 * Added silc_server_channel_has_local function to check whether channel
2378 has locally connected clients on the channel.
2380 * The silc_server_remove_from_one_channel now checks whether the
2381 channel has global users or not after given client was removed from
2382 the channel. It also checks whether the channel has local clients
2383 on the channel anymore. If it does not have then the channel entry
2384 is removed as it is not needed anymore.
2386 * The silc_server_notify now checks on JOIN notify whether the joining
2387 client is one of locally connected or global. If it is global then
2388 the channel has now global users on the channel and that is marked
2389 to the channel entry. Also, it now saves the global client to
2390 global list who is joining and JOINs it to the channel. This is
2391 for normal server, that is.
2393 Changed silc_server_send_notify_on_channel,
2394 silc_server_packet_relay_to_channel and
2395 silc_server_packet_send_to_channel check if we are normal server
2396 and client has router set (ie. global client) do not send the
2397 message to that client, as it is already routed to our router.
2399 * Implemented LEAVE notify type handling in silc_server_notify
2402 * Tested LEAVE command in router environment successfully. Tested
2403 with two routers, two servers and two clients.
2407 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2409 * Implemented SIGNOFF notify type handling in silc_server_notify
2412 * silc_server_remove_id now removes the client entry from all channels
2413 it has joined and thusly sends SIGNOFF notify type.
2415 * Rewrote the NAMES list generation in server by removing two excess
2416 loops. The lists are created now inside one loop.
2418 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2420 * silc_server_remove_channel_user checks now also global list
2421 for channel and client.
2423 * silc_server_new_channel_user checks now both local and global
2424 list for channel and client. Fixed a bug in client id decoding.
2425 Used to decode wrong buffer.
2427 * silc_server_channel_message checks now both local and global
2428 list for channel entry.
2430 * Tested channel joining (hence JOIN) in router environment
2431 successfully. Tested with two routers, two servers and two
2434 * Tested channel message sending in router environment successfully.
2436 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2438 * Added silc_server_save_channel_key into server.[ch] to save the
2439 received channel key in Channel Key payload processing. It is
2440 also used in JOIN command reply handling.
2442 Equivalent function silc_client_save_channel_key added into
2443 client.[ch] into client library.
2445 * Changed JOIN command reply to send information whether the channel
2446 was created or not (is existing already) and the channel key
2447 payload. Changed protocol specs accordingly.
2449 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2450 the request was sent by ID and not by nickname. Crashed on
2453 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2455 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2456 now correctly save the received data.
2458 * silc_server_free_sock_user_data now notifies routers in the
2459 network about entities leaving the network.
2461 At the same time implemented functions silc_server_remove_id
2462 and silc_server_send_remove_id to receive and send REMOVE_ID
2463 packets. The packet is used to notify routers in the network
2464 about leaving entities. The ID removed will become invalid in
2467 * Added function silc_idlist_del_server into server. Removes and
2468 free's server entry from ID list.
2470 * silc_server_private_message function now checks, if we are router,
2471 that the destination ID really is valid ID, naturally.
2473 * In router when NEW_ID packet is received (for new client) the
2474 hash of the Client ID is saved in the ID Cache but the
2475 client->nickname is set to NULL, instead of putting the hash
2478 IDENTIFY command now also checks that client->nickname must be
2479 valid. If it is not if will request the data from the server who
2480 owns the client. Added new function
2481 silc_server_command_identify_check.
2483 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2484 to set the command to already allocated Command Payload.
2486 * Tested private message sending in router environment with two
2487 routers, two servers and two clients. Fixed minor bugs and now
2490 * Fixed segfault from client's NAMES command. Used to crash if
2493 * Forwarded packets must not be routed even if it is not destined
2494 to the receiver. Changed server code comply with this.
2496 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2498 * Added `require_reverse_mapping' boolean value to ServerParams
2499 structure. If TRUE (not default) the server will require that
2500 the connecting host has fully qualified domain name.
2502 If the reverse mapping is not required and hostname could not be
2503 found the IP address is used as hostname.
2505 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2507 * Implemented version string checking to both client and server.
2508 The check is incomplete currently due to the abnormal version
2509 strings used in development version of SILC.
2511 * Changed all command functions in server to use the new
2514 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2516 * Changed char *data to unsigned char *data in ID Cache system to
2517 support binary data as ID Cache data. Changed code to support
2518 binary data in lib/silccore/idcache.c.
2520 * Renamed silc_server_packet_relay_command_reply to
2521 silc_server_command_reply as it is normal packet receiving
2522 function. Rewrote the function to accept command replys for
2523 servers and not only for clients.
2525 * Mark remote router always as registered server if we are connecting
2526 to it. Otherwise, commands sent by the router to us are ignored.
2528 * All ID List find routines now returns the ID Cache Entry pointer
2529 as well if requested.
2531 * WHOIS command works now in router environment, tested with two
2532 routers, two servers and two clients.
2534 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2535 in router environment (as it is almost equivalent to WHOIS) but
2536 hasn't been tested thoroughly. Added new functions:
2538 silc_server_command_identify_parse
2539 silc_server_command_identify_send_reply
2540 silc_server_command_identify_from_client
2541 silc_server_command_identify_from_server
2543 * Disabled route cache adding because adding two different ID's with
2544 same IP replaces the old cache entry thus giving wrong route.
2545 The entry->router->connection is always the fastest route anyway
2546 so route cache may not be needed. Of course, new routes maybe
2547 established after receiving the ID when the entry->router->connection
2548 might not be anymore the most optimal.
2550 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2552 * Add route cache for received ID for fast routing.
2554 * Added silc_server_packet_route to route received packet on router
2555 that is not destined to us.
2557 * Renamed silc_server_get_route to silc_server_route_get.
2559 * Added id_string and id_string_len fields into SilcServer to
2560 include encoded ServerID for fast comparing without excess
2561 encoding of the ID's.
2563 * Cleaned up WHOIS command on server side. Added following static
2566 silc_server_command_whois_parse
2567 silc_server_command_whois_check
2568 silc_server_command_whois_send_reply
2569 silc_server_command_whois_from_client
2570 silc_server_command_whois_from_server
2572 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2573 arguments in command replies. All command functions should be
2574 updated to use this macro.
2576 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2578 * Minor typo fixes on command reply handling on server.
2580 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2582 * Added silc_server_command_add_to_channel internal routine to add
2583 the client to the channel after router has created the channel and
2584 sent command reply to the server.
2586 * Added generic silc_server_send_command to send any command from
2589 * Use static buffer with ID rendering instead of duplicating data.
2591 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Fixed a channel user mode bug when joining to a channel server gave
2594 everybody channel founder rights, oops.
2596 * We mark ourselves as the router of the incoming server connection
2597 if we are router ourselves. This way we can check in some packet
2598 sending functions whether it is locally connected server. For
2599 incoming router connections we put NULL.
2601 * For router sending packets locally means now always sending the
2602 packet cell wide; to local clients and local servers. For normal
2603 server sending packet locally means sending it to only local
2606 * Fixed the JOIN command to really work in router environment. If the
2607 channel is created it is always created by the router. Router is
2608 also responsible of making the initial joining to the channel,
2609 sending JOIN notify to the sending server and distributing
2610 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2611 does not exist server doesn't do anything else but forward the
2612 command to the router which performs everything.
2614 * Added silc_server_send_channel_key function to send the Channel Key
2617 * Added silc_server_create_channel_key to create new channel key. The
2618 channel key is now re-generated everytime someone joins or leaves
2619 a channel, as protocol dictates. Note: channel->key_len is the
2622 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2624 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2625 packet_receive.[ch] to separate packet sending and receiving
2626 routines. The server.[ch] now includes everything else including
2627 actual packet processing (writing and reading data) and other
2630 Renamed silc_server_private_message_send_internal to
2631 silc_server_send_private_message. The routine is still though
2632 used only to relay private messages as server does not send
2633 private messages itself.
2635 Renamed silc_server_new_channel to silc_server_create_new_channel
2636 and added new function sicl_server_new_channel that handles the
2637 incoming New Channel packet. Added also new sending function
2638 silc_server_send_new_channel to send New Channel Payload.
2640 * Added new function silc_server_notify to process incoming notify
2641 packet to the server/router. Server may then relay the notify
2642 to clients if needed.
2644 * Added new function silc_server_new_channel_user to process incoming
2645 New Channel User packet. Router will redistribute the packet and
2646 send JOIN notify to its local clients and locally connected servers
2647 if needed. Normal server will send JOIN notify to its local client
2648 on same channel when received this packet. Added also corresponding
2649 sending function silc_server_send_new_channel_user to sent the
2652 * Added boolean route argument to send_notif_to_channel and
2653 packet_send_to_channel functions to attempt to route the packet
2654 if it is TRUE and send only locally if it is FALSE.
2656 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * silc_server_replace_id now broadcasts the received replace ID
2659 packet if it is not broadcast packet already. The router must
2660 broadcast to inform other routers about changed ID.
2662 * Added backpointer to server's router into SilcServer context in
2663 silcd/server_internal.h.
2665 * Fixed silc_server_packet_broadcast to send correct broadcast
2668 * The channel key is now distributed to the local client as soon
2669 as it is received from the router (in router environment) so that
2670 no other packet may be sent for the channel until client has
2673 * silc_server_remove_channel_user now broadcasts the received
2674 Remove Channel User packet if it is not broadcast packet already.
2675 The router must broadcast to inform other routers about removed
2678 * Added users field into SilcPacketContext that is a reference count
2679 of the context. One can increase the reference count by calling
2680 silc_packet_context_dup which is now changed to just increase the
2681 reference count instead of duplicating the data. The reference
2682 count is decresed by calling silc_packet_context_free that will
2683 free the data after the reference count hits zero.
2685 For now on the packet context and everything allocated into it
2686 (including the raw packet from network) must be freed by calling
2687 the new silc_packet_context_free function. Added also new function
2688 silc_packet_context_alloc that must be used now to allocate the
2689 context. This also means that if a routine is asynchronous from
2690 silc_[client/server]_packet_parse_type the packet context must
2691 be duplicated by calling silc_packet_context_dup. Otherwise it
2692 gets free'd after silc_[client/server]_packet_parse_type returns.
2693 Also, one must remember that if packet is duplicated then its
2694 reference count must be decresed by calling the free function as
2695 many times as it was duplicated.
2697 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2698 from both client and server.
2700 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2702 * Made joining to a channel working in router environment.
2704 * Cleaned up JOIN command on server side and create function
2705 silc_server_command_join_channel internal routine to make the
2708 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2710 * Changed silc_command_pending list to SilcDList. Also, added
2711 `ident' field to SilcServerCommandPending structure to identify
2712 the reply and to call correct callback.
2714 Added silc_server_command_pending_check function to replace the
2715 corresnponding macro. The silc_command_pending list is not
2718 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2719 to set identifier to previously allocated Command Payload. It
2720 is used to set identifier for command when resending Command
2723 * Added silc_command_payload_encode_payload to encode Command
2724 Payload buffer from SilcCommandPayload structure.
2726 * Added silc_argument_payload_encode_payload to encode Argument
2727 payload buffer from SilcArgumentPayload structure.
2729 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2731 * Changed WHOIS command to support router connection on server side.
2732 The whois request is always sent to router unless the server is
2733 standalone server. After server has received the reply from the
2734 router will it send the reply to the client.
2736 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2737 broadcast received broadcast packet. The function is used only
2738 by router. The broadcast packet is always sent to the router's
2741 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2742 render given ID to printable string, for log files for example.
2744 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2746 * Made basic router to router connections working. At least they
2747 can now connect to each other but nothing really works the way
2748 they are supposed - yet.
2750 * Added new initiator token to RouterConnection configuration
2751 file in silcd/serverconfig.[ch]. It is used to tell whether we
2752 are the initiator to the remote router or whether we'll expect
2753 the other end to connect.
2755 * Moved registering of listener task to silc_server_init, hence
2756 the server starts listenning as soon as it is run, even if it
2757 does not have connections to other routers. Let's see how well
2760 * Changed default connection retry timeouts for more suitable in
2763 * Removed cipher and such arguments from silc_idlist_add_client
2764 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2765 Added new function silc_idlist_add_data to add the keys and stuff
2768 * Added SilcIDListData structure and added it to SilcClientEntry
2769 and SilcServerEntry as their first field in the structure. This
2770 way we can explicitly cast the ID entries to the SilcIDListData
2771 structure and get common data for the entries. In past, we had
2772 to first check what type of connection it is and then cast it to
2773 correct ID entry type. Now, we can directly cast the opaque
2774 pointer to the SilcIDListData (no matter what ID entry it actually
2775 is) and get the data needed.
2777 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2779 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2780 in some circumstances even if threre were timeout tasks, though not
2781 IO tasks, but tasks anyway. Now fixed.
2783 * Defined SilcServerConnection structure to hold connection specific
2784 stuff about directly connected servers and routers. The definition
2785 is currently in silcd/server_internal.h. I thought about having
2786 a bit more important role fro this struct but for now it is used
2787 only when connecting to other server (or router actually).
2789 * Added connecting retry support in server when connecting to
2790 router(s). The retry feature implement exponential backoff
2791 algorithm. Also, added SilcServerParams structure to hold default
2792 parameters for server. For now, it include these retry settings
2793 and are hard coded. After server is moded to be as Silc Server
2794 Library this structure will be more important.
2796 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2798 * Changed client librarys channel->clients table to SilcList and
2799 changed code accordingly.
2801 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2803 * Changed client's channel table to SilcList and changed code
2804 accordingly. Also changed SilcChannelClientEntry to include back-
2805 pointer to the channel so that client entry can use that structure
2806 as list as well and we have fast cross-reference to the channel.
2807 This change dramatically decreased the complexity of channel
2808 handling with client entry and vice versa (removed one extra
2809 loop when searching for channel entry from many functions).
2811 * Changed server->sim from table to SilcDList and changed code
2814 * NAMES command can now be used from user interface. It will show
2815 the user list on the channel, neatly.
2817 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2818 Code now saves realname of the user if it becomes available.
2820 * Renamed configure.in to configure.in.pre and made ./prepare
2821 script to automatically add correct version string to
2822 configure.in which it creates from configure.in.pre.
2824 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2826 * NAMES command reply now shows users mode with the nickname when
2829 * Moved silc_client_ch[u]mode[_char] functions from
2830 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2831 place sucks, they are utility functions and should be in some
2834 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2836 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2839 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2843 * Added TRQ (efficient deque and list library) into lib/trq. This is
2844 a very good list library that is currently used in the SILC. Defined
2845 SilcList API over the library because I didn't like the API very
2846 much. See lib/trq/silclist.h for the API and examples of how to
2847 use the API. Fixed various places in the code to use the new
2848 SilcList API. The SilcList is meant for lists that has a structure
2849 already defined as a list. It is not suitable to add just some
2850 context to the list (in TRQ, the context is the list actually).
2852 So, I defined SilcDList that can be used for the purpose where
2853 predefined list structure does not exit. This can be used as
2854 such list. Now some context just can be added to the SilcDList.
2855 Currently this list is not used in the SILC just yet, though there
2856 are a lot places where this can replace dynamically allocated
2857 tables and I will fix these places, later, to use SilcDList.
2858 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2859 and use TRQ internally).
2861 Also fixed some annoying warning messages that the original TRQ
2862 code generated. Also minor changes to TRQ's Makefile.in.
2864 * Added support for querying by Client ID to both WHOIS and
2865 IDENTIFY commands into server, as required by the protocol.
2867 * Removed method function pointers from SilcBuffer structure. They
2868 weren't used to anything and just increased the context size for
2869 no good reason. This change also made silc_buffer_alloc and
2870 silc_buffer_free functions inline functions.
2872 * Disabled command flooding detection support until it's fixed so
2873 that it accepts commands in but does not execute them more than once
2876 * Added silc_net_localhost(), to return local hostname, into
2877 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2878 that must be initialized before calling silc_client_init.
2880 * Added new function: silc_server_send_notify_on_channels to send
2881 notify messages to all channels client has joined. It is assured
2882 that the message is sent only once per client.
2884 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2885 lib/silcutil/silcutil.[ch] as silc_format function. The new
2886 function is generic and is used by server as well, not only by
2887 the logging routines.
2889 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2890 the provided version string was not acceptable. Added new function:
2891 silc_ske_check_version into lib/silcske/silcske.h. The function
2892 must be implemented by the application (client or server) and it
2893 does not reside in the SKE library. The function checks the version
2894 string remote end sent.
2896 * Added back pointers (to opaque context and to SilcSocketConnection)
2897 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2899 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2900 duplicate packet context structure.
2902 * Changed `notify' client operation to send same arguments as client
2903 receives from server except for ID's. ID's are mapped to correct
2904 ID entry and that is returned. Also, if channel entry is not sent
2905 by server but the notify is for channel the channel entry is sent
2906 to application (otherwise application doesn't know that it is for
2907 channel (library gets it from packet's Destination ID)).
2909 * Added silc_client_remove_from_channels into client library to
2910 remove a client from all channels it has joined to. Used when
2911 received SIGNOFF notify from server. Added also new function
2912 silc_client_replace_from_channels to replace old ID entry with
2913 new ID entry on all channels. Used when received NICK_CHANGE
2916 * Fixed ID Cache list handling in silc_idlist_get_client in
2917 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2918 to get (or query) client by ID.
2920 * Updated TODO list.
2922 * Added connection authentication status message defined by the
2923 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2924 support for these into the code in client and server side.
2926 * Added generic function silc_client_send_command to send any command
2927 with variable argument list. Application should use this function
2928 to send commands if the command functions provided by the library
2929 does not suite for the application's user interface needs.
2931 * Added new `failure' client operation. Application is notified about
2932 received failure packet if client is executing a protocol. In this
2933 case the protocol's execution has failed.
2935 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2936 is required by the protocol.
2938 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2939 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2942 * Added status flag to SilcSKE object to indicate realtime status
2943 of the SKE protocol.
2945 * Application receives now exactly same command reply arguments as
2946 the library receives from server. However, if ID is received the
2947 corresponding ID entry is returned to the application (eg. Client
2948 ID is mapped to correct SilcClientEntry entry and that is returned).
2949 Changed command_reply client operation due to this change.
2951 * Changed all ID's in commands and in command replys as ID Payloads.
2952 Change affected both client and server side codes.
2954 All ID's sent in SILC network (with execption of ID's in SILC
2955 Packet header) are sent in ID Payload to support variable length
2958 * Server now notifies nick changes and notifies all clients on
2959 the channels about the new nickname (about the new Client ID,
2962 * Implemented CMODE command to change channel modes. Supports all
2963 channel modes defined by the protocol specs except ban and invite
2964 lists. (Also, private channel key mode is supported but support for
2965 setting private channel key in client is missing, thus, this mode
2966 has no effect on client side (except that server requires that the
2967 client uses private channel key and normal channel traffic does not
2970 Also, invite mode works per se, but INVITE command does not work
2971 yet correctly, so you can set channel as invite only channel but
2972 inviting clients to the channel does not work (it is yet to be
2973 thought what's the best way to do it).
2975 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2976 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
2977 Implemented CUMODE command to change user's mode on the channel.
2978 Supports all modes defined by the protocol specs.
2980 * Added NAMES command reply to return users modes on the channel.
2982 * Removed unnecessary and slow ciphers from lib/silccrypt.
2984 * Set SO_KEEPALIVE option to connection sockets by default.
2986 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
2988 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
2989 redefined the Notify Payload into protocol specs.
2991 * Added silc_id_payload_parse_id to get ID directly from raw
2994 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2996 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
2997 accept searching by Client ID as well.
2999 * Added support for LEAVE and SIGNOFF notify types in client library.
3001 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3002 to parse ID Payload from raw data.
3004 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3006 * Added flags parameter into silc_ske_assemble_security_properties
3007 function in lib/silcske/silcske.[ch].
3009 * Changed notify client operation to fit better for notify messages
3010 sent by server. The notify payload received from server is now
3011 passed to the application (after parsing it to SilcNotifyPayload).
3012 It is application's responsibility to retrieve the arguments
3013 from the payload and show the message the way it wants. The message
3014 sent by server is implementation specific.
3016 * Changed public keys to comply with the protocol specification.
3017 Old public keys are not supported anymore and are not compatible.
3019 * Removed nickname from Channel Payload as the latest draft removed
3020 it. The client must resolve the nickname from the NAMES command
3021 reply received when it joined the channel.
3023 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3025 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3027 * Fixed some errors in protocol specification drafts.
3029 * Created lib/silccore/silcnotify.c to implement Notify Payload
3030 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3031 generic payloads described by protocol specifications. The file
3032 includes implementations for ID Payload and Argument Payload.
3034 * Changed Command Payload implementation to use the new Argument
3035 Payload. Changed command_xxxx_payload to command_payload_xxxx
3036 to comply with SILC coding conventions.
3038 * Added suppport for Argument Payload handling in Notify Payload
3039 implementation as protocol requires it. Added the new support
3040 into server and client lib as well.
3042 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3044 * Added support for multiple nicknames on same channel. [n] is
3045 added locally to the nickname if there are more than one same
3046 nicknames on the channel.
3048 * Server now sends all nicknames that matched WHOIS request.
3049 Client also shows the list received from server.
3051 * Added TOPIC command to client side. User can now set and show
3052 current topic on channel.
3054 * Added MOTD command to client and server. Also, server sends the
3055 motd when client connects to the server.
3057 * Changed version strings to comply ISO 8601.
3059 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3061 * Fixed protocol error handling in client library. It should now
3062 cope even if the SKE fails for some reason.
3064 * Made new protocol specification drafts for submitting to IETF.
3066 * Implemented TOPIC command to server in silcd/command.c.
3068 * Added two new notify types into lib/silccore/silcnotify.h:
3069 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3070 notify nickname change and topic setting/change on a channel.
3072 * API change of command_reply operation in client library. The
3073 application gets now the status type received from server as well.
3075 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3077 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3079 * Cras fixed and optimized the packet handling even further and
3080 it should work now. Minor change to the prototype of function
3081 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3083 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3085 * Added new function into lib/silcutil/silcschedule.[ch]:
3086 silc_schedule_with_fd to select() a specified fd. The function
3087 returns after timeout expires or data arrives or goes. The
3088 function is used by packet routines to wait that all data is
3089 received from network.
3091 * Fixed data reading from network in lib/silccore/silcpacket.c.
3092 The code now assures that all data is read from the fd and then
3093 continues packet processing. This was a bug fix since the code
3094 used to drop some data in some circumstances.
3096 * Added new function into lib/silcclient/client.[ch]:
3097 silc_client_start_key_exchange to start key exchange after
3098 connection has been established to server. The code internally
3099 now uses this funtion but its main purpose was to provide it
3100 for applications that perform their own connecting. After
3101 application has created a connection it merely calls this
3102 function to start the key exchange between client and server.
3103 The library takes care of everything else after that.
3105 Updated also lib/silcclient/README to explain the usage of
3108 * Do not send to application information that connection has
3109 been established. Application gets notified it by connect
3112 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3114 * Applied cras's patch to add silc_schedule_one function. The
3115 function runs scheduler once and returns.
3117 * Fixed the scheduler after cras messed it up. The timeout
3118 handling works now as it's supposed to work.
3120 * Added into lib/silccore/ silcnotify.h to include notify
3121 message types support. Changed silc_server_send_notify*
3122 functions, in server.[ch], to support those new notify types.
3123 Added the support for the notify types into client library,
3124 as well. Added new notify client operation into ops.h in
3127 * Changed silc_server_packet_send_to_channel to send normal
3128 packets instead of just channel message packets. The function
3129 is now used to send the notify packets to channels. It is not
3130 used to send channel message packets anymore, as server never
3133 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3134 va_arg()s as it seems to require it nowadays. I guess, if SILC
3135 is compiled with older va_arg() the new code should work anyway.
3137 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3139 * Splitted core library. Core library (lib/silccore) includes
3140 now only SILC protocol specific core (and common) components.
3141 Created new utility library (lib/silcutil) that includes more
3142 generic purpose stuff. The stuff for util library was taken
3143 from the old core library. This was minor and easy split.
3145 * Created SILC Client Library (lib/silcclient) that includes
3146 implementation of the SILC client without user interface. This
3147 was major move from silc/ directory. The code has been changed
3148 so that it is transparent towards the user interface. The
3149 silc/ directory includes now the same user interface as before
3150 and it uses the new client library. Read lib/silcclient/README.
3151 Basicly, the client library performs everything else related
3152 to SILC except user interface handling. Also, configuration
3153 files are considered to be part of user interface and library
3154 does not handle them.
3156 This change also changed a lot of structures, function naming etc.
3157 Most important change was that SilcClientWindow object was
3158 renamed to SilcClientConnection in the client library. Created
3159 also new file lib/silcclient/ops.h. Also added new files
3160 silc/local_command.[ch] and silc/client_ops.[ch].
3162 All these changes were made to make it easier for user interface
3163 designers to create what ever user interface for the SILC client
3166 It is also expected that the server will be moved to lib
3167 directory as well and SILC Server Library will be created;
3168 sometimes in the future.
3170 * Removed Local commands from lib/silccore/silccommand.h as
3171 they are application specific and new client library does not
3172 handle any of those anymore.
3174 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3175 old client implementation in silc/.
3177 * Added support for callback functions in SILC_LOG_* macros.
3178 Application can now set its own callbacks that will be called
3179 instead of using the default functions that will always print
3180 the debug messages to stderr (or stdout). Also, debugging can
3181 now be disabled by setting silc_debug to FALSE and re-enabled by
3182 setting it to TRUE. Note, that logging will still work even
3183 if debugging is disabled.
3185 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3186 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3187 silc_log_reset_debug_callbacks.
3189 * To enable debugging in silc client one must give now -d
3190 option on command line.
3192 * Changed silc_schedule_init to automatically allocate task queues
3193 if they are not allocated before calling it.
3195 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3197 * Added GMP 3.1 into math library.
3199 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3201 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3202 a channel in SILC network. The packet is used by servers and
3203 routers to notify other routers that user has left a channel.
3204 This little feature was missing until now. Added the feature
3205 to protocol specification as well.
3207 Added functions: silc_server_send_remove_channel_user and
3208 silc_server_remove_channel_user into server.[ch].
3210 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3211 lib/silccore/silcpacket.h. However, they are not implemented
3214 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3216 * Fixed joining to a channel and sending channel messages
3217 between server and router. The channel message sending should
3218 now work inside a cell.
3220 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3222 * Fixed the private message sending between server and router.
3223 The private message sending should now work inside a cell.
3225 * Added silc_server_replace_id into server.[ch] to replace
3226 existing ID in the SILC network.
3228 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3229 and silc_idlist_replace_server_id into idlist.[ch] in server.
3231 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3233 * Fixed the server to server connections. Server can again now
3234 connect to router. Router to router connections probably does
3237 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Added dynamic protocol registering support. Now protocols can
3240 registered and unregistered on the fly. Patch by cras.
3242 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3244 * Added lib/contrib directory to hold routines that some platforms
3245 don't have but are needed by SILC.
3247 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3248 into lin/contrib to provide getopt() and getopt_long() for
3249 those who don't have it.
3251 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3253 * Added AWAY command to client. When away message is set and
3254 client receives a private message packet the client automatically
3255 replies to the sender with the away message.
3257 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3258 bug seemed to be the cause of recent problems when compiling
3261 * Added version detection support to SKE protocol specification
3262 and added the new changes to the SKE implementation as well.
3263 There were other minor changes in the SKE protocol as well.
3265 Many changes in lib/silcske/silcske.[ch] and in
3266 lib/silcske/payload.[ch].
3268 * Added ^U functionality, clear input line. Patch from cras.
3270 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3272 * Mainly small bugfixes on core library. Fixed some debugging
3273 logging and buffer overflow in silclog.c.
3275 * Updated config.sub and config.guess on the distribution tree.
3277 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3279 * Added command lagging support in server. Client may execute
3280 commands now only once in two seconds.
3282 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3284 * Optimized packet reception. MAC computation and checking is now
3285 also more optimized. A lot previously duplicated code is now
3286 used as generic by both client and server.
3288 * Fixed key pair generation in clientutil.c
3290 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Added into lib/silccore/silcbufutil.[ch] new function;
3293 silc_buffer_realloc.
3295 * Moved generic packet sending/encryption functions to
3296 lib/silccore/silcpacket.[ch] from client and server. Some
3297 rewriting of the functions.
3299 * Moved all generic packet reception/decryption functions to
3300 lib/silccore/silcpacket.[ch] from client and server. The
3301 packet processing is now much cleaner in both client and server.
3302 These were major changes in both client and server.
3304 * Created many common functions in server to do packet sending.
3305 Previously code were duplicated a lot, this has been removed
3308 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3310 * Rewrote major parts of the ID cache system. Don't know
3311 whether it is better now or not but at least the API is more
3314 * Major rewrite on ID cache stuff on client because of the ID
3315 cache API changes. Added idlist.c to client.
3317 * Also major rewrite on ID cache stuff on server as well.
3318 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3319 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3320 in hand, instead they are all put into the ID cache system now.
3321 All server_idlist_* routines uses ID cache now instead of
3322 traversing its own lists (those lists does not exist anymore).
3323 SilcIDList though still exists. Also, SilcXXXEntry's are
3326 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3328 * Finally made the SKE implementation compliant to the protocol
3329 specification. All mp integers are now binary encoded as
3330 opposed being HEX encoded.
3332 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3335 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3336 functions: silc_[encode/decode]_pem. Also added function
3337 silc_encode_pem_file to PEM encode with newlines ('\n') for
3340 * SILC public keys are now encoded either PEM or binary. Same
3341 option is for private keys as well. By default private keys
3342 are binary encoded and public keys PEM encoded. Silly HEX
3343 encoding were removed.
3345 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3346 function to create fingerprints.
3348 * Fixed a bug in SHA1; does not change the original data anymore.
3350 * Partly implemented INFO command on client and server side.
3351 Fixed CLEAR command. Changes to SERVER command; show current
3352 server(s) when giving command without arguments. Added
3353 VERSION command to client.
3355 * Added check to server that unregistered connections cannot
3356 execute commands (unless it is specificly allowed).
3358 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3360 * Fixed screen refresh.
3362 * Fixed channel joining bug from client. On some circumstances
3363 client tried to join to a channel it had already joined.
3365 * Added public key verification process into client's protocol.c.
3366 The client now verifies the public key from user and saves
3367 it into ~./silc/serverkeys/ directory.
3369 Added into: clientutil.[ch]: silc_client_verify_server_key.
3371 * Changed SKE protocol's silc_ske_initiator_finish function
3372 to accept callback function that verifies the received public
3373 key. Removed old silc_ske_verify_public_key function.
3375 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3377 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3378 silc_pkcs_private_key[_data]_set.
3380 * Made the password and public authentication more cleaner in
3381 server's protocol.c.
3383 * Removed historic and obsolete protocol `channel_auth' from
3384 both client and server.
3386 * Removed wrong way of sending command status messages from
3387 server to client in server's command.c. The old way violated
3388 protocol specification.
3390 Changes to silccore/silccommand.[ch]: removed
3391 silc_command_encode_status_payload -> not needed anymore,
3392 changed silc_command_encode_payload_va to accept extra
3393 argument on variable argument list. The argument type must
3394 now be provided to the function. Also, added new function:
3395 silc_command_encode_reply_payload_va which is same as
3396 normal command_encode_payload_va except command status type
3397 is provided as extra argument.
3399 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3401 * Added ~./silc directory handling. The directory includes the
3402 public and private keys for the client.
3404 Added silc_client_check_silc_dir, silc_client_create_identifier
3405 and silc_client_load_keys.
3407 * Implemented SILC protocol compliant public key. Added public
3408 and private key saving to and loading from files.
3410 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3411 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3412 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3413 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3414 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3416 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3417 silc_pkcs_load_[public/private]_key.
3419 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3421 * Added silc_server_get_route (route.[ch]) to get connection
3422 data for the fastest route for given ID.
3424 * Implemented INVITE command on client and server. The command
3425 were re-defined in the SILC Protocol Specification and the
3426 implementation now complies with the specification.
3428 * Implemented PING command on client and server.
3430 * Implemented NAMES command on client and server. The server side
3431 supports currently only normal server not router server yet.
3432 Some changes to NAMES definition in SILC protocol specification.
3434 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Implemented LEAVE command on client and server.
3438 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3439 again. This change was made to the protocol as well. Server
3440 should not violate the protocol specification anymore.
3442 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3444 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3445 was tested. SOCKS4 was not but should work anyway.
