1 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Check minor version as well in the SKE. Affected files are
4 silcd/protocol.c and lib/silcclient/protocol.c.
6 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * Register default ciphers and stuff when using -C option with
9 the server. Affected file sildc/silcd.c.
11 * Put back the servers public key filename format, it is better
12 than the new one. For now, the client keys are saved with the
13 new filename format. The affected file silc/client_ops.c.
15 * Implemented the Cipher API for the rest of the ciphers that
16 did not implement it or implemented it the wrong way.
18 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
20 * Register default ciphers and stuff when using the -S option
21 in the client. Affected file silc/silc.c. Same also when
22 creating new key pair with -C option.
24 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
26 * Fixed the silc_verify_public_key client operation function to
27 save the public keys differently. The fingerprint is now
28 used as filename and not the hostname. This way also the
29 client keys are saved uniquely and not with hostnames. The
30 affected file is silc/client_ops.c.
32 * Trimmed the silc_hash_fingerprint function to remove extra
33 whitespaces from the end of the fingerprint. The affected
34 file is lib/silccrypt/silchash.c.
38 * Added silc_cipher_register_default function to register all
39 default ciphers. It can be used when configuration files
40 does not exist and the application does not want any specific
41 ciphers in any specific order.
43 The SilcDList is now used as silc_cipher_list dynamically
44 allocated cipher list. Removed the static list all together
45 and now all ciphers must be allocated to the dynamic list.
46 The silc_cipher_alloc routine was changed to check only the
49 All silc_cipher_* routines that used to return int returns
52 The affected files lib/silccrypt/silccrypt.[ch].
54 * The same thing was done to silc_hash_* as for silc_cipher_*
55 routines. Affected files lib/silccrypt/silchash.[ch].
57 * The same thing was done to silc_pkcs_* as for silc_cipher_*
58 routines. Affected files lib/silccrypt/silcpkcs.[ch].
59 Added also silc_pkcs_[un]register[_default] functions.
60 Removed the data_context from the PKCS API.
62 * Added silc_hmac_register_default function to register default
63 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
64 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
65 to unregister all hmacs at once.
67 * Register the default ciphers, hash functions, PKCSs and HMACs
68 if client's configuration file does not exist. The affected
71 * The client did not load the hash functions from the SIM
72 modules at all. Added support for this. Affected file is
75 * When decoding public key with silc_pkcs_public_key_decode, check
76 the supported algorithm only if PKCS are registered. Affected
77 file lib/silccrypt/silcpkcs.c. The same was done with the
78 silc_pkcs_private_key_decode.
80 * Fixed the SILC List routines to keep the list always in order.
81 It used to change the list's order when traversing the list but
82 not it preserves the order. Affected file lib/trq/silclist.h.
84 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
86 * Added the client library to use the SilcSocketConnection's
87 reference counter (by silc_socket_dup) to prevent the bug that
88 the socket object may be freed underneath async operation.
90 * The name resolv library checking fixes in the configure.in.pre.
93 * Created new version of the protocol drafts for future
94 development. The -03 drafts are the ones that will be changed
95 in the trunk now and the -02 will remain as they are.
97 * Send list of CUMODE notifys to the router when announcing
98 the channel users to the router. Affected file silcd/server.c.
99 If the router receiving channel founder CUMODE for a channel
100 that already has channel founder it will send CUMODE notify
101 to the sender to remove the channel founder rights from the
102 announced client. Affected file silcd/packet_receive.c.
104 * The CUMODE notify may now use Server ID as well as the entity
105 who changes the mode. Updated protocool specs.
107 * Updated INSTALL and README files.
109 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
111 * New web pages in the http://silc.pspt.fi. The pages was
116 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
118 * Implemented the [DenyConnectin] config section in the server.
119 Added silc_server_config_denied_conn to check whether incoming
120 connection is denied. Affected file silcd/serverconfig.[ch].
122 * Do not check the ports when checking the incoming configuration
123 data if the port is 0, meaning any. Affected file is
124 silcd/serverconfig.c.
126 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
128 * Fixed buffer overflow in silc_string_compare in the file
129 lib/silcutil/silcutil.c.
131 * Fixed double free in silc_server_command_leave in the file
134 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
136 * Fixed the version checking in the server. Affected file is
139 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
141 * Fixed the configuration data fetching when accepting new
142 connections in the server. Affected file silcd/server.c.
144 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
146 * Added `sender_entry' argument to the function
147 silc_server_packet_relay_to_channel so that we can check
148 whether some destination actually belongs to the same route
149 the sender belongs (ie, we must not resend the packet to the
150 sender). Affected file silcd/packet_send.[ch].
152 * Added `servername' field to the SilcClientEntry in the server
153 to hold the name of the server where client is from. Affected
154 file is silcd/idlist.h.
156 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
158 * Moved the channel message encrypting in the router betwen
159 router connections from silc_server_channel_message to the
160 silc_server_packet_relay_to_channel since we want to check
161 whether we have anybody channel before encrypting anything.
162 Affected files silcd/packet_[receive/send].c.
164 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
166 * Fixed the [AdminConnection] server config section to support
167 multiple entries. Affected file silcd/serverconfig.c.
169 * Added support into the server to check the validity of the
170 incoming connection before executing any KE or authentication
173 * The connection configuration is now saved to the KE and
174 connection auth protocol contexts and not fetched anymore in
175 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
177 * The local hosts listenning address and port is also resolved
178 now when starting the server. We want to have the socket object
179 to include the real address and port for the listener. Added
180 new function silc_net_check_local_by_sock into the files
181 lib/silcutil/silcnet.[ch].
183 * Fixed a broadcast bug in server -> do not broadcast if we
186 * Fixed a routing bug. Do not route broadcast packets ever.
187 Broadcast packets must be processed always and not routed since
188 they may be destined to some other host than yourself and thus
189 would get routed without no good reason. Affected file is
192 * Added function silc_server_config_is_primary_route to check
193 whether primary router connection has been configured (a router
194 configuration that we are initiating). If there is not, we
195 will assume that there is only two routers in the SILC network
196 and we will use the incoming router connection as our primary
197 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
199 * Changed the order of the broadcasting. Broadcast _after_ the
200 packet has been processed not before. Affected file is
203 * Fixed a [ClientConnection] parsing bug. The port was never
204 parsed correctly thus resulting to port 0. Affected file
205 silcd/serverconfig.c.
207 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
208 argument and did not set the broadcast packet flag. Affected
209 file silcd/packet_send.c. Fixed same bug in the function
210 silc_server_send_notify as well.
212 * If we receive NEW_ID packet for our own ID in the server, ignore
215 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
219 * Removed the nickname from the Private Message Payload.
220 Updated the code and the protocol specs.
222 * Updated protocol specs for submitting to the IETF.
224 * Tweaked the Random Number Generator a bit. Affected file
225 lib/silccrypt/silcrng.c. Exported a new function
226 silc_rng_[global]_add_noise which can be used to add more
229 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
231 * Do not parse packets with different timeout when protocol
232 is active -> may cause problem with rekey. Affected file
235 * When server receives signoff notify it must not create
236 new channel key if the client is on any channels since the
237 sender of the signoff notify will create it.
239 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
241 * Added printing of error messages during SKE protocol from the
242 failure packet sent by server during SKE. Affected file
245 * Removed the client's failure_callback handling with timeout
246 and handle it immediately when received.
248 * The SKE library returned wrong type in SUCCESS and FAILURE
249 packets. They must be 32 bit MSB not 16 bit MSB.
251 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
253 * Ok, rewrote the logic of the re-key and now it seems to work.
254 I tested it on high traffic with frequent re-keys without
255 problems. Added hmac_receive (and renamed hmac to hmac_send)
256 in SilcClientConnection in lib/silcclient/client.h and
257 in SilcIDListData in silcd/idlist.h. Also, removed the
258 SilcPacketParserContext's cipher and hmac fields as they are
259 not needed anymore and actually caused some problems when
260 the ciphers and hmac's changed underneath the packet parser.
262 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
264 * If re-key protocol is active then process the incoming packets
265 synchronously since we must assure that icoming packets encrypted
266 with the old key is processed before the new keys is set to
267 use. This is true other packets than for REKEY packets.
268 Affected file silcd/server.c. The same was done to client library
269 as well, affected file lib/silcclient/client.c.
271 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
273 * Fixed bug in client and server to accept the force send if
274 the packet is send from silc_[server/client]_packet_process
275 function. Otherwise the packets are never delivered, oops.
277 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
279 * Disable force sending of packets when REKEY protocol is active.
280 We must assure that no packet is sent directly when rekey is
281 performed. All packets must be sent through packet queue.
282 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
283 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
284 function is silc_[server/client]_packet_send_real to check
287 * Replaced the SIM paths from example config files to
288 /usr/local/modules. Also, make install creates now
289 /usr/local/silc/logs directory to hold all the SILC server
292 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
294 * Made the configure.in.pre work on Solaris. Patch by salo.
296 * Made all ciphers compatible with non-x86 machines. Defined
297 CBC mode macros into lib/silccrypt/ciphers_def.h.
299 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
301 * Fixed the make install.
303 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
305 * When MAC computation fails the silc_packet_decrypt returned 0
306 even though it was supposed to return -1. Fixed this. The
307 affected file is lib/silccore/silcpacket.c.
309 * Do not replace the config files in /etc/silc (in make install)
310 if they already exist. Affected file ./Makefile.am.
312 * Do not send re-key packets immediately but through packet queue.
313 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
315 * Changed silc_net_check_host_by_sock to return FALSE if the
316 IP/DNS could not be resolved. Though, it returns the IP address
317 now even if it could not resolve it (but returns also FALSE).
318 Affected file lib/silcutil/silcnet.[ch].
320 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
322 * Added silc_pkcs_decode_identifier to decode the public key's
323 identifier. Affected file lib/silccrypt/silpkcs.[ch].
324 Added also silc_pkcs_free_identifier. Added also new context
325 SilcPublicKeyIdentifier.
327 * Added -S option to the silc client. It is used to dump the
328 contents of the specified public key file.
330 * Changed the PKCS api to return the public key length when
331 setting the public key.
333 * Fixed a fatal bug in the public and private key file loading.
334 Affected file lib/silccrypt/silcpkcs.c.
336 * Execute the packet parsing for client with zero (0) timeout
337 if the protocol is active. Affected file silcd/server.c.
339 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * Made the key generation options to the silcd program. Added
342 -C option, equivalent to client's option.
344 * Added new [ServerKeys] config section to the server. It
345 configures the server's public and private key.
347 * Defined generic Public Key Payload into the protocol
348 specification to send specific type of public keys and
351 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
352 public key or certificate.
354 * Implemented the GETKEY command to the server and to the
355 client library and on user interface.
357 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
359 * Made preliminary `make install' work.
361 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
363 * Added SilcServerRekey context into silcd/idlist.h.
365 * Added the PFS support as defined in the specification to the
366 SKE protocol. Affected files lib/silcske/*.c.
368 * Added `ske_group' field to the SilcServerRekey context to hold
369 the number of the SKE group that is used with PFS in re-key.
370 Affected file silcd/idlist.h.
372 * Added PFS re-key support to the server. Affected file is
375 * Added silc_protocol_cancel to cancel execution of the next
376 state of the protocol. Affected file is
377 lib/silccore/silcprotocol.[ch].
379 * Added the re-key support with and without PFS to the client
380 library. Re-key is performed once in an hour, by default.
382 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
383 Added silc_client_rekey_callback and silc_client_rekey_final.
384 Affected files are lib/silcclient/protocol.[ch] and
385 lib/silcclient/client.[ch].
387 * Removed the `hmac_key' and `hmac_key_len' fields from the
388 SilcClientConnection structure; not needed. Affected file is
389 lib/silcclient/client.h.
393 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
395 * Do not ask whether user wants to use the negotiated private key
396 for private messages, just use it. Affected file is
397 silc/local_command.c.
399 * Added `send_enc_key' and `enc_key_len' fields to the
400 SilcIDListData structure since they are needed in the re-key
401 phase. Affected file is silcd/idlist.[ch].
403 * Implemented the simple re-key protocol into the server.
404 Affected files silcd/server.c and silcd/protocol.[ch]. The
405 re-key will be performed once in an hour, by default.
407 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
408 Added silc_server_rekey, silc_server_rekey_callback and
409 silc_server_rekey_final.
411 * Removed Tunneled flag from the protocol. Updated the code
412 and the specifications.
414 * Adde `pfs' field to the SilcIDListData to indicate whether
415 the PFS is to be performed in the re-key. Affected file is
418 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
420 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
421 int64 of at least the xintXX size. If void * is less that 4
422 bytes uint32 * will be used. Defined bool as boolean.
424 * Changed _ALL_ unsigned long and unsigned int to uint32,
425 unsgined short to uint16 in the source tree.
427 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
428 not handle clients that has entry->data.registered == FALSE.
429 They are not in the network anymore. Affected file is
432 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
434 * Implemented the sending of the SERVER_SIGNOFF notify in the
435 server. Affected file is silcd/server.c.
437 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
438 Added also silc_notify_payload_encode_args into the
439 lib/silccore/silcnotify.[ch].
441 * Implemented ther SERVER_SIGNOFF notify handling in the server.
442 Affected file silcd/packet_receive.c.
444 * Implemented the SERVER_SIGNOFF notify handling in the client
445 library. Affected file lib/silcclient/client_notify.c. Also,
446 implemnted the printing of the SERVER_SIGNOFF info to the
447 application. Affected file silc/client_ops.c.
449 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
450 if the deleting was successful. Affected file silcd/idlist.[ch].
452 * Added support for public key authentication in the connection
453 authentication protocol in the client library. Affected file
454 lib/silcclient/protocol.c.
456 * Changed the server's silc_idlist_get_clients_by_* interface
457 to support already allocated array so that new entries may be
458 added to pre-allocated array. Affected file silcd/idlist.[ch].
459 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
462 * All command reply functions in the server now calls the
463 pending command callback even if error occured. This way the
464 error will be delivered to the client as well. Affected files
465 silcd/command.c and silcd/command_reply.c.
467 * Fixed INFO command to return local server's info if no server
468 was provided. Affected file lib/silcclient/command.c.
470 * Removed RESTART command for good. Updated the code and the
473 * Rewrote parts of the task system. It is a bit simpler now.
474 Removed unsued task priorities. The affected files are
475 lib/silcutil/silctask.[ch].
477 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
479 * Moved the USERS printing from the library to the application.
480 Affected files lib/silcclient/command.c and silc/client_ops.c.
482 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
486 * Added channel key re-key support. The re-key is perfomed
487 only by the router and is done once in an hour. Added `rekey'
488 field to the SilcChannelEntry in the server. Affected files
489 silcd/server.c and silcd/idlist.h.
491 * Added silc_task_unregister_by_context into the file
492 lib/silcutil/silctask.[ch].
494 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
496 * Added SILC_UMODE_GONE mode to indicate when the client is not
497 present in the SILC network. Added also support to the local
498 command AWAY that will set this mode. Added support of showing
499 "xxx is gone" in WHOIS command. The USERS command shows the
502 * Fixed setting server and router operator privileges in the
503 server's UMODE command. Affected file silcd/command.c.
505 * Merged the SKE KE1 and KE2 payloads into one payload. The
506 new KE payload is equivalent to the old KE2 payload.
508 Cleaned up the SKE Start Payload parsing. It now uses the
509 simple buffer unformatting to do the parsing. A lot faster
512 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
513 to the SKE that is used to indicate whether both of the SKE
514 parties should perform authentication. By default only the
515 responder performs authentication. By setting this flag also
516 the initiator must do authentication. By default it is unset
517 since in normal SKE case, client to server connection, only
518 the responder should do authentication. When doing SKE between
519 two clients both should perform authentication. Updated the
520 code and the protocol specs.
522 * A little fix to IDENTIFY command in the server. Search the
523 client first by hash not nickname. Affected file is
526 * Fixed the silc_client_close_connection to support closing
527 the client to client connections wihtout deleting too much
528 data. Affected file lib/silcclient/client.c.
530 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
531 are received if protocol used to be active but is not anymore
532 the application would crash due to NULL pointer dereference.
533 Affected files silcd/server.c and lib/silcclient/client.c.
535 * Added `hash' field to the SilcClientConnection to include
536 the hash function negotiated in the SKE protocol.
538 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
539 to set the channel founder authentication data. A client can
540 claim the founder rights later by providing the authentication
541 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
542 This way the channel founder can regain the channel founder
543 privileges even it is left the channel. This works only on
544 local server and the client must be connected to the same
545 server to be able to regain the founder rights. Updated the
546 protocol specs accordingly.
548 Added support to the CMODE command in the client to set the
549 founder auth data. Read the README to see how to set it.
551 Added support to the CUMODE command to claim the founder
552 rights. Read the README to see how to do it.
554 Added support for the founder authentication to the Channel
555 Entry in the server. Affected file silcd/idlist.h.
557 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
558 server's CMODE command. Affected file silcd/command.c.
560 * Added the following new functions into lib/silccore/silcauth.[ch]:
561 silc_auth_get_method and silc_auth_get_data.
563 * The server now saves the remote hosts public key to the
564 SilcIDListData pointer. Affected file silcd/protocol.c.
566 * The normal server now does not remove the channel entry from
567 the cache if the founder authentication data is set. It used
568 to remove it if the founder was the last one on the channel on
569 the server and left the channel. The auth data is saved and
570 if the channel is re-joined later the old entry is used with
571 the old auth data. Affected files silcd/command_reply.c and
574 * Removed the `pkcs' field from the SilcIDListData structure
575 in the server; it is not used. Affected file silcd/idlist.h.

579 * Fixed packet processing on slow links. Partial packets were
580 never re-processed because the incoming data buffer was cleared
581 by the application. Application must not directly clear the
582 sock->inbuf, the packet processing routines handle it. Fixed
583 this in client library and in server.
585 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
587 * Fixed the WHOIS and IDENTIFY send reply function to really
588 check whether to send list or just one entry. Affected file
591 * Cleaned up the LEAVE command's channel key distribution. The
592 affected file silcd/command.c.
594 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
595 can enforce the channel mode as well. In that case the ID
596 includes the ID of the server. The code now enforces the
597 mode change if the router have different mode than the server.
599 * The notify client operation with CMODE_CHANGE notify can now
600 return NULL client_entry pointer if the CMODE was not changed
601 by client. Application must check for this.
603 * Added <Server ID> argument to INFO command to support server
604 info fetching by Server ID.
606 * Added silc_server_announce_get_channel_users to get assembled
607 packets of channel users of the specified channel. Affected
608 file silcd/server.[ch].
610 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
611 was freed underneath the ID Cache.
613 * Re-announce clients when the server received CHANNEL_CHANGE
614 notify from the router. Affected file silcd/packet_send.c.
616 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
618 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
619 crashed since it did not handle the fact that there is no cipher
620 called "3" and didn't check the error condition. Now fixed.
622 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
623 flag. It can be used to send message requests.
625 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
627 * Implemented the RESTART command in the client.
629 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
630 notice type messages. Added notice printing to the user
633 * The channel keys are not re-generated if the channel's mode
634 is PRIVKEY, ie private key on the channel exists. Affected
635 files silcd/server.c and silcd/command.c.
637 * Fixed a little bug in channel message delivery when channel
638 private keys are set in the server. Affected file is
641 * Changed the setting on channel->on_channel = TRUE from the
642 silc_client_save_channel_key to the JOIN command reply. The
643 key payload is not received if the private channel key is set.
644 Affected file lib/silcclient/command_reply.c and the
645 lib/silcclient/client_channel.c.
647 * When the CMODE_CHANGE notify is sent and the channel private
648 key mode is removed the channel key must be re-generated in
649 other cells as well. Added this support for the router in the
650 silcd/packet_receive.c.
652 * Added new local command NOTICE to send notice message on
653 channel. Affected file silc/local_command.[ch].
655 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
657 * Added new local command ME to the client. It is used to send
658 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
659 some action. Affected file silc/local_command.[ch].
661 * Changed channel_message and private_message client operations
662 to deliver the message flags to the application. Added also
663 the `flags' arguments to the silc_client_send_channel_message
664 and silc_client_send_private_message functions. Affected file
667 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
669 * Redefined the Private Message Payload to support private message
670 keys and to support the new private message flags. Updated
671 the protocol specs. Flags makes it possible to have for example
674 * Added new type SilcPrivateMessagePayload and defined an API
675 for it in the lib/silcclient/silcprivate.[ch].
677 * Tested private message private keys successfully. Tested the
678 private message key set, unset and list commands with the new
681 * Redefined the Channel Message Payload to include the channel
682 message flags (equal with private message flags) to support
683 for example CTCP style messages.
685 * Defined some of the message (for channel and private message)
686 flags. Updated the protocol specs and added the flags to the
687 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
689 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
691 * Added SilcKeyAgreementStatus type to the key agreement routines
692 to indicate the current status and error if one occured.
693 The status types are defined in the lib/silcclient/silcapi.h.
695 * Added new local command KEY that is used to set and unset private
696 keys for channels, set and unset private keys for private messages
697 with remote clients and to send key agreement requests and
698 negotiate the key agreement protocol with remote client. The
699 key agreement is supported only to negotiate private message keys,
700 it currently cannot be used to negotiate private keys for channels,
701 as it is not convenient for that purpose.
703 * Fixed a minor pending callback setting bug in the function
704 silc_client_get_client_by_id_resolve, now the function works.
705 Affected file lib/silcclient/idlist.c.
707 * Added function silc_net_get_local_port to get local bound
708 port by socket. Added to lib/silcutil/silcnet.[ch].
710 * Added `sockets' and `sockets_count' fields to the SilcClient
711 object. They hold the sockets of the listenning sockets in
712 the client. Listenning sockets may be for example the key
713 agreement server. Affected file lib/silcclient/client.[ch].
714 Added functions the silc_client_add_socket and the
715 silc_client_del_socket. They are exported to the application
718 * Added ~./silc/clientkeys to support other client's public keys.
720 * Renamed verify_server_key client operation to verify_public_key
721 and added one argument to indicate the type of the connection
722 (server, client etc.).
724 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
726 * Added silc_server_connection_auth_request to handle the
727 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
728 silcd/packet_receive.[ch].
730 * Added silc_server_send_connection_auth_request into the
731 silcd/packet_send.c to send the connection auth request packet.
733 * Cleaned up the silcd/protocol.c a bit and fixed some memory
736 * Fixed the public key authentication in responder side in the
737 server. The `auth_data' pointer includes the SilcPublicKey
738 not the path to the public key. Affected file silcd/protocol.c.
740 * Implemented the public key authentication in the initiator side
741 in the server. Affected file silcd/protocol.c.
743 * Removed the [RedirectClient] config section from the server
744 configuration. Is not needed and I don't want to implement it.
746 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
748 * Cleaned up the CMODE command in the server. It now works
749 correctly and supports all the modes defined in the protocol.
750 Affected file is silcd/command.c.
752 * Added `hmac_name' field to the SilcChannelEntry in the server
753 to hold the default HMAC of the channel. It can be set when
754 creating the channel (with JOIN command). Affected files
757 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
758 type to indicate the change of the current cipher and hmac
759 on the channel. Client can safely ignore the <cipher> argument
760 (if it chooses to do so) since the CHANNEL_KEY packet will
761 force the channel key change anyway. The <hmac> argument is
762 important since the client is responsible of setting the new
763 HMAC and the hmac key into use.
765 * Fixed the CMODE command in the client library as well.
767 * Tested CMODE command in router environment successfully.
769 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
771 * Show the version of the remote client (or server) when connecting
772 to the server. It is logged to the log file. Affected file
775 * Fixed the KILLED notify handling in the client library. The
776 client must be removed from all channels when receiving the
779 Also, do not remove the client entry when giving the KILL
780 command but when the KILLED notify is received.
782 * Removed silc_idlist_find_client_by_nickname from the server.
783 Not needed anymore. Affected files silcd/idlist.[ch].
785 * Implemented the CHANNEL_CHANGE notify type handling to the
786 server. Affected file silcd/server.c.
790 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

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

842 * Redefined parts of the SilcChannelEntry in the server to support
843 the new ban and invite lists.
845 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
847 * Redefined the INVITE command. The same command can be used to
848 invite individuals to the channel but also to manage the invite
849 list of the channel (to add to and remove from the invite list).
850 Updated the protocol specs.
852 * Added new command SILC_COMMAND_BAN that can be used to manage
853 the ban list of the channel. Updated the protocol specs.
855 * Removed the channel modes: the SILC_CMODE_BAN and the
856 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
857 in the CMODE command. The equivalent features are now available
858 using INVITE and BAN commands. Updated the protocol specs.
860 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
861 in the network about change in the current ban list. The notify
862 type is not used by the client.
864 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
865 support the invite lists.
867 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
869 * Added new function silc_string_regexify that converts string
870 including wildcard characters into regex string that can
871 be used by the GNU regex library. Added into the file
872 lib/silcutil/silcutil.[ch].
874 Added silc_string_regex_combine to combine to regex strings
875 into one so that they can be used as one regex string by
876 the GNU regex library. Added into the file
877 lib/silcutil/silcutil.[ch].
879 Added silc_string_regex_match to match two strings. It returns
880 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
882 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
884 * Imported GNU regex to the soruce tree into lib/contrib.
885 Fixed some compiler warning from the regex.c.
887 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
889 * Fixed MOTD command in the server to work in router environment.
891 * Fixed the MOTD command in the client library to support
892 the server argument in the command.
894 * Added `nickname_len' argument to the silc_idlist_add_client
895 in the server, as the `nickname' argument may be binary data
898 * Added silc_idlist_get_channels to return all channels from
901 * Implemented LIST command to the server. Affected file is
904 * Implemented the LIST command to the client library and on the
907 * Added [<user count>] argument to the LIST command reply.
908 With private channels the user count is not shown.
910 * Updated TODO and README.
912 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
914 * The client entry's data.registered must be TRUE even with
915 global client entry on global client list. The data.registered
916 is used to check whether the client is anymore in the network,
917 for example with WHOWAS command so it must be valid.
919 * Fixed the WHOWAS command in the server. It now actually works
920 in router environment. Added function into silcd/command_reply.c
921 silc_server_command_reply_whowas_save.
923 * Added silc_idlist_purge function to the silcd/idlist.c
924 to periodically purge the ID Cache.
926 * Fixed INFO command in the server. It works now in router
927 environment. Added <server name> argument to the INFO command
928 reply. Updated the protocol specs.
930 * Fixed minor bug in silc_idcache_purge to not purge if the
931 expire value is zero.
933 * Fixed various bugs in WHOIS and IDENTIFY command handling as
934 they were buggy because of the WHOWAS information.
936 * Fixed local command MSG to handle the async resolving of
937 the remote client properly. It used to fail the first MSG.
938 Affected file silc/local_command.c.
940 * Added `data_len' field to SilcIDCache context.
942 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
944 * Update TODO. Todo in commands in the server.
946 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
948 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
949 used by routers as broadcast packet to inform other routers
950 about the changed user mode.
952 Implemented the notify handling in the server. Affected file is
953 silcd/packet_receive.c. Added the function
954 silc_server_send_notify_umode to the silcd/packet_send.[ch].
956 * Added new generic Channel Payload and deprecated the New Channel
957 Payload. The New Channel Payload is now the generic Channel
960 * Added new argument `mode' to the silc_server_send_new_channel
961 as it is required in the Channel Payload now.
963 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
964 and created a new and real SilChannelPayload to represent the
965 new generic Channel Payload. Implemented the encode/decode
966 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
968 * Added silc_server_get_client_channel_list to return the list
969 of channels the client has joined for WHOIS command reply.
970 Affected file silcd/server.[ch].
972 * Implemented the channel list sending in the WHOIS command reply
973 in server and in the client.
975 Implemented the channel list displaying on the user interface
976 as well. Affected file silc/client_ops.c.
978 * Added silc_channel_payload_parse_list to parse list of Channel
979 Payloads. It returns SilcDList list of SilcChannelPayloads.
980 Client for example can use this function to parse the list of
981 channels it receives in the WHOIS command reply. The caller
982 must free the list by calling silc_channel_payload_list_free.
983 Affected files lib/silccore/silcchannel.[ch].
985 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
987 * Added one new argument <user mode> to the WHOIS command reply
988 to return the mode of the user in SILC. Updated the protocol
991 Implemented it to the server and client.
993 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
995 * Fixed the mode printing on the user interface on joining.
996 Affected file silc/client_ops.c.
998 * Implemented the UMODE command and user modes in general to the
999 client library and to the user interface.
1001 * Implemented the UMODE command to the server.
1003 * The server now sends UNKNOWN_COMMAND error status if client sends
1004 unknown command. Affected file silcd/command.c.
1006 * All server commands now handle the command identifier the right
1007 way when sending the command reply to the client. The client can
1008 use to identify the command replies with the identifier.
1010 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1012 * Added silc_server_get_client_route to resolve the route to
1013 the client indicated by the client ID. Affected file is
1016 * Added silc_server_relay_packet as general function to relay
1017 packet to arbitrary destination. This deprecates functions
1018 like _send_private_message_key, _relay_notify etc. Affected
1019 file is silcd/packet_send.[ch].
1021 Removed silc_server_send_key_agreement,
1022 silc_server_send_private_message_key and
1023 silc_server_packet_relay_notify functions from the file
1024 silcd/packet_send.[ch].
1028 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1029 server. Affected file silcd/packet_receive.[ch].
1031 * Implemented the KILL command to the client. Implemented the
1032 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1033 Affected files lib/silcclient/command[_reply].c and
1034 lib/silcclient/client_notify.c. Implemented the KILL notify
1035 printing in the user inteface.
1037 * Fixed a lot silc_parse_nick memory leaks from the client
1038 library in the file lib/silcclient/command.c.
1040 * Changed the silc_server_send_notify_on_channels's `sender'
1041 argument from SilcSocketConnection to SilcClientEntry to
1042 check the sender as entry and not as connection object and not
1043 to send to the client provided as argument. The affected file
1044 is silcd/packet_send.[ch].
1046 * The notify packets that are destined directly to the client used
1047 to not to be processed by the server. Now changed that and the
1048 server processes all notify packets. After relaying the packet
1049 to the client the notify packet is processed in the server.
1051 * The silc_server_free_client_data now checks whether there is
1052 pending outgoing traffic for the client and purges the data to
1053 the network before removing the client entry.
1055 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1057 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1058 an client is killed from the SILC Network. Updated the protocol
1061 Added new function silc_server_send_notify_killed to the
1062 silcd/packet_send.[ch].
1064 * Added function silc_server_packet_relay_notify to relay notify
1065 packets that are destined directly to a client. In this case
1066 the server does not process the notify packets but merely relays
1067 it to the client. Affected file silcd/packet_send.[ch].
1069 Added also silc_server_packet_process_relay_notify to check
1070 whereto relay the notify. Affected file is
1071 silcd/packet_receive.[ch].
1073 * Implemented the KILL command to the server.
1077 * Added the backup schema desgined last fall to the protocol
1078 specs for everyone to see. The specification is in the
1079 *-spec-xx.txt draft and the packet type definitions for the
1080 backup routers is in *-pp-xx.txt draft. Thusly, added also
1081 new packet type SILC_PACKET_CELL_ROUTERS.
1083 * A big security problem in the implementation discovered. The
1084 signoff of an client did not cause new channel key generation
1085 which it of course should've done. The channel keys must be
1086 always re-generated when client leaves (or signoffs) the channel.
1087 The silc_server_remove_from_channels funtion now handles
1088 the channel key re-generation.
1090 * Added `sender' argument to the silc_server_send_notify_on_channels
1091 to not to send the client provided as argument. Affected file
1092 silcd/packet_send.[ch].
1094 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1096 * Implemented OPER and SILCOPER commands into the server and
1099 * Added silc_auth_verify and silc_auth_verify_data to verify
1100 the authentication directly from the authentication payload.
1101 It supports verifying both passphrase and public key based
1102 authentication. Affected file lib/silccore/silcauth.[ch].
1104 * Added `hash' field to the SilcIDListData structure. It is the
1105 hash negotiated in the SKE protocol. Affected file is
1108 * Slight redesigning of the SilcAuthPayload handling routines.
1109 Do not send SilcPKCS but SilcPublicKey as argument.
1111 * Implemented the public key authentication support to the
1112 serverconfig. The public key is loaded from the provided path
1113 and saved as authentication data to void * pointer. Thus,
1114 changed the unsigned char *auth_data to void *auth_data;
1116 * Fixed SHUTDOWN command to send the reply before the server
1117 is shutdown. :) Affected file silcd/command.c.
1119 * Fixed fatal bug in CONNECT command. The hostname was invalid
1120 memory and server crashed. Affected file silcd/command.c.
1122 * Fixed fatal bug in CLOSE command. The server_entry became
1123 invalid but was referenced later in the command. Affected file
1126 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1128 * Fixed fatal bug in failure packet handling. Server ignored
1129 the failure and thus crashed when it came.
1133 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1135 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1136 that the command may be executed only once in (about) 2 seconds.
1137 The old SILC_CF_LAG flag is same but allows command bursts up
1138 to five before limiting.
1140 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1141 server code. Various commands now includes the CF_LAG_STRICT
1142 flag to disallow any kind of miss-use of the command.
1144 * Fixed the silc_buffer_unformat to not to allocate any data
1145 if the length of the data is zero. It used to allocate the
1146 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1148 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1150 * Changed the format of AdminConnection configuration section
1151 in the server. Added username of the admin to the format.
1152 Affected files silcd/serverconfig.[ch].
1154 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1155 to return admin configuration data by host, username and/or
1158 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1160 * Implemented WHOWAS command to the server. Added the functions:
1162 silc_server_command_whowas_parse,
1163 silc_server_command_whowas_send_reply,
1164 silc_server_command_whowas_from_client and
1165 silc_server_command_whowas_from_server
1167 * Added <Client ID> argument to the WHOWAS command reply. Updated
1168 the protocol specs accordingly.
1170 * Implemented WHOWAS command and command_reply to the client
1173 Implemented the WHOWAS printing on the user interface.
1175 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1177 * Added new argument to the WHOWAS command reply, the real name.
1178 It is an optional argument. Updated the protocol specs.
1180 * Added SilcIDCacheDestructor callback that is registered when
1181 the SilcIDCache is allocated. The callback is called when
1182 an cache entry in the ID Cache expires, or is purged from the
1183 cache. Added into lib/silccore/idcache.[ch].
1185 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1186 to destruct the client entries when the cache entry expires.
1187 Other ID Cache's in server and in the client library ignores
1190 * If the ID Cache entry's `expire' field is zero then the entry
1191 never expires. Added boolean `expire' argument to the
1192 silc_idcache_add function in the lib/silccore/idcache.[ch].
1193 If it is TRUE the default expiry value is used.
1195 * Added silc_server_free_client_data_timeout that is registered
1196 when client disconnects. By default for 5 minutes we preserve
1197 the client entry for history - for WHOWAS command.
1199 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1201 * Added support to the server to enforce that commands are not
1202 executed more than once in 2 seconds. If server receives
1203 commands from client more frequently, timeout is registered
1204 to process the commands. Affected file silcd/command.c.
1205 Added new function silc_server_command_process_timeout.
1207 * Changed NICK_NOTIFY handling in client library to check that
1208 if the client's nickname was changed, so there is no need to
1209 resolve anything from the server.
1211 * Removed error printing from the WHOIS and IDENTIFY commands.
1212 If error occurs then it is ignored silently in the client library.
1213 The application, however, may map the received error to
1214 human readable error string. The application currently maps
1215 the NO_SUCH_NICKNAME error to string.
1217 * Made the command status message public to the application. Moved
1218 them from lib/silcclient/command_reply.c to
1219 lib/silcclient/command_reply.h. The application can map the
1220 received command status to the string with the
1221 silc_client_command_status_message function.
1223 * Added check to the server to check that client's ID is same
1224 as the Source ID in the packet the client sent. They must
1227 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1229 * Added dist-bzip hook to the Makefile.am to make bzip2
1230 compressed distributions.
1232 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1234 * Server now enforces the maximum length for the nickname and
1235 the channel as protocol specification dictates. 128 bytes for
1236 nickname and 256 bytes for channel name.
1238 * Moved the WHOIS printing to the application. The client libary
1239 does not print out the WHOIS information anymore, the application
1240 must do it. Renamed silc_client_command_reply_whois_print to
1241 the silc_client_command_reply_whois_save.
1243 The client's idle time is also sent to the application now, and
1244 the idle is shown on screen.
1246 * Added silc_client_command_reply_identify_save to save the
1247 received IDENTIFY entries.
1249 * Do not check for channel private keys in message sending and
1250 reception if the channel does not have the PRIVKEY mode set.
1251 Affected file lib/silclient/client_channel.c.
1253 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1255 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1256 just surfaced after chaning the JOIN procedure.
1258 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1260 * Added silc_client_get_clients_by_list to get client entries
1261 from Client ID list, that is returned for example by JOIN
1262 and USERS command replies. The application should use this
1263 function for example when JOIN command reply is received to
1264 resolve the clients already on the channel (library does not
1265 do that anymore as USERS command reply is not used in the JOIN
1266 procedure anymore). Affected files lib/silcclient/silcapi.h and
1267 lib/silcclient/idlist.c.
1269 * JOIN command reply and USERS command reply returns now SilcBuffer
1270 pointers instead of unsigned char pointers when returning
1271 the client list and mode list.
1273 * Added <Client ID> argument to the JOIN command reply, mainly
1274 for the server to identify for which client the command was
1275 originally sent. Updated protocol specs accordingly.
1277 * Added SilcDlist private_key pointer to the SilcChannelEntry
1278 in the client to support the channel private keys. Affected
1279 file is lib/silcclient/idlist.h.
1281 * Added SilcChannelPrivateKey argument to the function
1282 silc_client_send_channel_message so that application can choose
1283 to use specific private ke if it wants to. If it is not provided,
1284 the normal channel key is used, unless private keys are set.
1285 In this case the first (key that was added first) is used
1286 as the encryption key.
1288 * Implemented the support for channel private key handling.
1289 Implemented the following functions:
1291 silc_client_add_channel_private_key,
1292 silc_client_del_channel_private_keys,
1293 silc_client_del_channel_private_key,
1294 silc_client_list_channel_private_keys and
1295 silc_client_free_channel_private_keys
1297 Affected file lib/silcclient/client_channel.c.
1299 * Added the support for the private keys in the channel message
1300 sending and encryption and in the message reception and
1301 decryption. Affected funtions are
1302 silc_client_send_channel_message and silc_client_channel_message.
1304 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1306 * Added SKE's key verify callback to the client library's
1307 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1309 * Removed the statement that server (or router) must send USERS
1310 command reply when joining to the channel so that the client
1311 knows who are on the channel. Instead, the client list and
1312 client's mode list is now sent in the JOIN command reply to the
1313 client who joined channel. This is better solution.
1315 * Added function silc_server_get_users_on_channel and function
1316 silc_server_save_users_on_channel to the silcd/server.[ch].
1318 * Removed function silc_server_command_send_users from the
1321 * Do not show topic on the client library anymore. The topic is
1322 sent in the command reply notify to the application and the
1323 application must show the topic now.
1325 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1327 * Added client searching by nickname hash into the IDENTIFY and
1328 WHOIS commands in the server as they were clearly missing from
1329 them. Affected file is silcd/command.c.
1331 * Fixed a bug in private message receiving in the client library.
1332 The remote ID was freed and it wasn't supposed, now it is
1335 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1337 * Minor fix to the channel payload; allocate the data area, as it
1338 needs to be of specific length.
1340 * If the key agreement port is zero then the operating
1341 system will define the bound port. Affected files are
1342 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1344 * Added new function silc_channel_payload_decrypt into the file
1345 lib/silccore/silcchannel.[ch].
1347 * Moved the channel message etc, check from silc_packet_decrypt
1348 to applications. The library calls now a generic
1349 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1350 when the packet is either normal or special. This was done to
1351 allow more wide range of checking that was not allowed when
1352 the code was in library. Now applications can do virtually any
1353 checks to the packet and return to the library the decision how
1354 the packet should be processed. Affected files are
1355 lib/silccore/silcpacket.[ch].
1357 Added silc_server_packet_decrypt_check to the server and
1358 silc_client_packet_decrypt_check to the client library.
1360 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1361 to send with specified source and destination information.
1363 * Channel message delivery between routers was broken after the
1364 channel key distribution was fixed earlier. The channel key
1365 was used be to distributed to other routers as well which is not
1366 allowed by the protocol. Now this is fixed and channel keys
1367 really are cell specific and the channel message delivery between
1368 routers comply with the protocol specification.
1370 * Fixed various commands in server to check also the global list
1371 for the channel entry and not just the local list. The affected
1372 file silcd/command.c.
1374 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1376 * Added assert()s to buffer formatting and unformatting routines
1377 to assert (if --enable-debug) when error occurs. Affected
1378 file: lib/silcutil/silcbuffmt.c.
1380 * Changed to auto-reconnect to check whether the remote host is
1381 router and register the re-connect timeout if it is. It used
1382 to check that whether we are normal server, but router must do
1383 auto-reconnect with another router as well. Affected file
1386 * Removed the [<key len>] option from CMODE command as the cipher
1387 name decides the key length, nowadays. See the defined ciphers
1388 from the protocol specification.
1390 * Added [<hmac>] option to the CMODE command to define the HMAC
1391 for the channel. Added SILC_CMODE_HMAC channel mode.
1393 * Added [<hmac>] option for the JOIN command so that user can
1394 select which HMAC is used to compute the MACs of the channel
1397 * Added Hmac field to the Channel Message Payload. The integrity
1398 of plaintext channel messages are now protected by computing
1399 MAC of the message and attaching the MAC to the payload. The
1400 MAC is encrypted. Now, it is clear that this causes some
1401 overhead to the size of the packet but rationale for this is that
1402 now the receiver can verify whether the channel message decrypted
1403 correctly and also when private keys are set for the channel the
1404 receiver can decrypt the packet with several keys and check from
1405 the MAC which key decrypted the message correctly.
1407 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1408 lib/silccrypt/silccipher.[ch].
1410 * Added silc_hash_len to return the digest length into the
1411 lib/silcrypt/silchash.[ch].
1413 * Rewrote parts of Silc Channel Payload interface in the
1414 lib/silccore/silcchannel.[ch]. The encode function now also
1415 encrypts the packet and parse function decrypts it.
1417 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1419 * Fixed a minor formatting bug in the SKE's key material processing.
1420 It actually might have processed the keys wrong way resulting
1423 * Redefined the mandatory HMAC algorithms and added new algorithms.
1424 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1425 and hmac-md5 truncated to 96 bits. The mandatory is now
1426 hmac-sha1-96. Rest are optional (including the one that used
1427 to be mandatory). Rationale for this is that the truncated HMAC
1428 length is sufficient from security point of view and can actually
1429 make the attack against the HMAC harder. Also, the truncated
1430 HMAC causes less overhead to the packets. See the RFC2104 for
1433 * Added new [hmac] configuration section. The SKE used to use
1434 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1435 is of course wrong. The official names that must be proposed in
1436 the SKE are the ones defined in the protocol specification
1437 (hmac-sha1-96 for example). The user can configure any hmac
1438 using any hash function configured in the [hash] section. At
1439 least, the mandatory must be configured.
1441 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1443 * Added HMAC list to the SKE proposal list. It has now both
1444 hash algorithm list and HMAC list. This makes the protocol
1445 incompatible with previous versions. The SKE now seems to work
1446 the way it is supposed to work, for the first time actually.
1448 * Defined plain Hash algorithms to the protocol specification.
1451 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1453 * Implemented support for key agreement packets into the server.
1454 Added functions silc_server_key_agreement and
1455 silc_server_send_key_agreement. Other than these functions,
1456 server has nothing to do with this packet.
1458 * Added support for private message key packets into the server.
1459 Added functions silc_server_private_message_key and
1460 silc_server_send_private_message_key.
1464 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1465 called in the protocol's final callback instead in the END
1466 protocol state. This makes a little more sense and in the same
1467 time in client we can use the same protocol routines for normal
1468 key exchange and to key agreement packet handling as well.
1470 * Added to both client's and server's KE protocol context the
1471 SilcSKEKeyMaterial pointer to save the key material. We will
1472 bring the key material to the protocol's final callback by doing
1473 this. The final callback must free the key material.
1475 * Added SKE's packet_send callback into client's KE protocol
1476 context so that the caller can choose what packet sending function
1477 is used. This way we can use different packet sending when
1478 doing normal SKE when doing key agreement packet handling (in
1479 the key agreement packet handling we do not want to encrypt
1482 * Implemented the responder side of the key agreement routines
1483 in the client. The client can now bind to specified port and
1484 accept incoming key negotiation. The key material is passed
1485 to the application after the protocol is over.
1487 * Implemented the processing of incoming Key Agreement packet
1488 in the client. Added function silc_client_key_agreement to
1491 * Implemented the intiator side of the key agreement routines
1492 in the client. The client can now initiate key agreement with
1493 another remote client. The key material is passed to the
1494 application after the protocol is over.
1496 * Created client_keyagr.c to include all the key agreement
1499 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1500 SILC_TASK_CALLBACK except that it is not static.
1502 * Created client_notify.c and moved the Notify packet handling
1503 from the client.[ch] into that file.
1505 * Created client_prvmsg.c and moved all private message and
1506 private message key routines from the client.[ch] into that file.
1508 * Create client_channel.c and moved all channel message and
1509 channel private key routines from the client.[ch] into that file.
1511 * Changed silc_client_get_client_by_id_resolve to resolve with
1512 WHOIS command instead of IDENTIFY command, in the file
1513 lib/silclient/idlist.c.
1515 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1517 * Implemented the SKE's responder side to the Client library.
1519 * When FAILURE is received to the protocol do not trust it
1520 blindly. Register a timeout to wait whether the remote closes
1521 the connection as it should do it, only after that process the
1522 actual failure. This was changed to both client and server.
1524 * Added client_internal.h to include some of the structures
1525 there instead of client.h in lib/silcclient/.
1527 * Added function silc_task_unregister_by_callback to unregister
1528 timeouts by the callback function.
1530 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1532 * Some "Incomplete WHOIS info" errors has been appearing on the
1533 log files. Took away the entry->userinfo check from WHOIS
1534 reply sending. The entry->userinfo is now " " if client did not
1535 provide one. I thought this was fixed earlier but something
1536 is wrong still. Let's see if the error still appears.
1538 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1540 * Fixed a minor bug in the login when the channel key is
1541 re-generated in the server. It used to generate the key in
1542 wrong order and thus caused problems in the channel traffic.
1544 * Fixed a minor bug in channel key distsribution after
1545 KICK command. The key was not sent to the router even though
1548 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1550 * Added silc_ske_process_key_material_data as generic routine
1551 to process any key material as the SILC protocol dictates. The
1552 function is used by the actual SKE library but can be used by
1553 applications as well. This relates to the private message keys
1554 and the channel private keys since they must be processed the
1555 same way the normal SILC session keys. The protocol dictates
1556 this. Affected files: lib/silcske/silcske.[ch].
1558 Added also silc_ske_free_key_material to free the
1559 SilcSKEKeyMaterial structure.
1561 * Defined silc_cipher_set_key function to set the key for
1562 cipher without using the object's method function. The affected
1563 files: lib/silccrypt/silccipher.[ch].
1565 * Implemented silc silc_client_add_private_message_key,
1566 silc_client_add_private_message_key_ske,
1567 silc_client_del_private_message_key,
1568 silc_client_list_private_message_keys and
1569 silc_client_free_private_message_keys functions in the
1572 Added functions silc_client_send_private_message_key to send
1573 the Private Message Key payload and silc_client_private_message_key
1574 to handle incoming Private Message Key payload.
1576 * Added Cipher field to the Private Message Key payload to set
1577 the cipher to be used. If ignored, the default cipher defined
1578 in the SILC protocol (aes-256-cbc) is used.
1580 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1582 * Removed lib/silcclient/ops.h file.
1584 Redefined parts of the SILC Client Library API. Created new
1585 file silcapi.h that deprecates the ops.h file and defines the
1586 published Client Library API. Defined also private message key
1587 API and channel private key API into the file.
1589 This is the file that the application must include from the
1590 SILC Client Library. Other files need not be included by
1591 the application anymore.
1593 * Added new key_agreement client operation callback and also
1594 defined the Key Agreement library API for the application.
1596 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1598 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1599 is used by clients to request key negotiation between another
1600 client in the SILC network. If the negotiation is started it
1601 is performed using the SKE protocol. The result of the
1602 negotiation, the secret key material, can be used for example
1603 as private message key.
1605 Implemented the Key Agreement payload into the files
1606 lib/silccore/silauth.[ch].
1608 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1610 * Redefined ciphers for the SILC protocol. Added some new ciphers
1611 and defined the key lengths for the algorithms. Changed the
1612 code accordingly. The default key length is now 256 bits.
1614 * Fixed SKE key distribution function silc_ske_process_key_material
1615 when the key length is more than 128 bits. The default key
1616 length in SILC is now 256 bits.
1618 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1619 to indicate unsupported algorithm.
1621 * Renamed rijndael.c to aes.c and all functions as well.
1623 * Fixed a long standing channel key setting bug in client library.
1624 Weird that it has never surfaced before.
1626 * Fixed bug in channel deletion. If the entire channel is removed
1627 then it must also delete the references of the channel entry
1628 from the client's channel list as the client's channel entry and
1629 the channel's client entry share same memory.
1631 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1633 * Implemented CONNECT and SHUTDOWN commands in the client.
1635 * Implemented CLOSE command to the client.
1637 * Added the function silc_idlist_find_server_by_name into the
1638 files silcd/idlist.[ch].
1640 Added the function silc_idlist_find_server_by_conn into the
1641 files silcd/idlist.[ch].
1643 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * DIE command was renamed to SHUTDOWN. Updated the both code
1648 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1649 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1651 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1654 * Added function silc_server_create_connection function to create
1655 connection to remote router. My server implementation actually
1656 does not allow router to connect to normal server (it expects
1657 that normal server always initiates the connection to the router)
1658 so the CONNECT command is only good for connecting to another
1661 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1663 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1664 or some other client was kicked from the channel.
1666 Implemented the handling of the notify type to both client
1669 Implemented silc_server_send_notify_kicked to send the KICKED
1670 notify. It is used to send it to the server's primary router.
1672 * Implemented the KICK command into server and client.
1674 * Added `query' argument to the silc_idlist_get_client function
1675 to indicate whether to query the client from server or not if
1678 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1679 to indicate that the client is not channel founder.
1683 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1685 * Removed the rng context from SilcPacketContext structure and
1686 changed that the packet routine uses the Global RNG API.
1688 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1690 * Added support for quit message that client can "leave" on the
1691 channel when it quits the SILC. It is ditributed inside the
1692 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1694 Added silc_server_free_client_data that will take the
1695 signoff message as argument.
1697 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1699 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1701 * Updated parts of the protocol specification to keep it up
1704 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1706 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1707 payloads in one packet.
1709 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1710 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1711 use now the new List flag.
1713 * Also deprecated the following packet types: REPLACE_ID,
1714 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1716 * Added list support for Notify packet in server.
1718 * Added silc_server_send_notify_channel_change to send the
1719 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1720 the silc_server_send_replace_id.
1722 * Added silc_server_send_notify_nick_change to send the
1723 NICK_CHANGE notify type. Deprecates the function
1724 silc_server_send_replace_id.
1726 * Added silc_server_send_notify_join to send the JOIN notify type.
1727 Deprecates the function silc_server_send_new_channel_user.
1729 * Added silc_server_send_notify_leave to send LEAVE notify type.
1730 Deprecates the function silc_server_send_remove_channel_user.
1732 * Added silc_server_send_notify_cmode and
1733 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1734 types. Deprecates the silc_server_send_set_mode function.
1736 * Added SERVER_SIGNOFF notify type to indicate that server has
1737 quit. This means that all clients on the channel from that
1738 server will drop. This can be also used when netsplit happens.
1740 Deprecated REMOVE_ID packet type since it is not needed anymore
1743 Added silc_server_send_notify_server_signoff to send the
1744 SERVER_SIGNOFF notify type. Deprecates the function
1745 silc_server_send_remove_id.
1747 Added also silc_server_send_notify_signoff to send the
1748 SIGNOFF notify type.
1750 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1751 SILC protocol from this day on. Changed the protocol
1752 specification as well.
1754 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1755 notify type. It is used between routers to notify about
1756 topic changes on a channel.
1758 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1761 * Partly updated the protocol specification to comply with the
1762 changes now made. It is still though a bit outdated.
1764 * The JOIN notify type now takes one extra argument <Channel ID>.
1765 The packet used to be destined to the channel but now the
1766 JOIN type may be sent as list thus it is impossible to
1767 destine it to any specific channel. By adding this argument
1768 it is again possible.
1770 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1772 * Added CREDITS file. The CHANGES and CREDITS file will appear
1773 in the distribution as well.
1775 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1777 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1778 types in the server's silcd/packet_receive.c.
1780 * Implemented CMODE and CUMODE to work in router environment.
1782 * Fixed minor encoding and decoding buglet from the
1783 lib/silccore/silcmode.c.
1785 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1788 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1790 * Changed all SilcConfigServer* and silc_config_server* to
1791 SilcServerConfig* and silc_server_config*, respectively.
1794 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1796 * Associated the ID (client or server ID) to the Authentication
1797 Payload to avoid any possibility of forging. Updated the
1798 protocol specification and the code accordingly.
1800 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1802 * The RSA key length is now save to the RsaKey context in the
1803 key generation process in lib/silccrypt/rsa.c. The key length
1804 is now used to figure out the maximum size of the block allowed
1805 to be encrypted/signed.
1807 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1808 is equivalent to the silc_mp_mp2bin but does not allocate any
1811 * Changed silc_mp_mp2bin API to take length argument. If it is
1812 non-zero then the buffer is allocated that large. If zero, then
1813 the size is approximated using silc_mp_sizeinbase, which however
1816 * Created Global RNG API which is global RNG that application can
1817 initialize. After initializing, any routine anywhere in the
1818 code (including library) can use RNG without allocating a new
1819 RNG object. This was done to allow this sort of use of the
1820 RNG in code that has no chance to allocate RNG object. All
1821 applications currently allocate this and many routines in the
1822 library use this. Affected file lib/silccrypt/silcrng.[ch].
1824 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1825 it to use the Global RNG API.
1827 * Defined Authentication Payload into protocol specification that
1828 is used during SILC session to authenticate entities. It is
1829 used for example by client to authenticate itself to the server
1830 to obtain server operator privileges.
1832 Implemented this payload into the lib/silccore/silcauth.[ch].
1833 Implemented also routines for public key based authentication
1834 as the new protocol specification dictates.
1836 Moved definitions of different authentication methods from
1837 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1839 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1840 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1841 silc_pkcs_verify_with_hash functions into the file
1842 lib/silccrypt/silcpkcs.[ch].
1844 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1846 * The client entry's userinfo pointer must be always valid.
1847 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1848 will fail since it requires the userinfo. Now, the userinfo
1849 is allocated as "" if actual userinfo does not exist. Actually,
1850 it must exist and it is totally Ok to drop client connections
1851 that does not announce the userinfo. However, we will make
1852 this workaround for now.
1854 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1855 to return the remote port by socket.
1857 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1859 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1860 SILC_SERVER_PENDING_EXEC and added an new macro
1861 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1862 data or when error occurs while processing the pending command.
1864 Added new argument `destructor' into silc_server_command_pending
1865 and to the SilcServerCommandPending object. This destructor is
1866 now called after calling the pending callback or if error occurs
1867 immediately. If error occurs the actual pending callback won't
1868 be called at all - only the destructor. The destructor may be
1869 NULL if destructor is not needed.
1871 All this applies for client library code as well. Similar
1872 changes were made there as well for the pending commands.
1874 In the client, the application must now allocate the
1875 SilcClientCommandContext with the silc_client_command_alloc
1878 * Added reference counter to the SilcServerCommandContext. Added
1879 function silc_server_command_alloc and silc_server_command_dup
1882 Same type of functions added to the client library for the same
1885 * Removed the cmd_ident from IDListData away since it is now
1886 global for all connections. It is the command identifier used
1887 in command sending and with pending commands. The affected file
1890 * Added reference counter to the SilcSocketConnection objecet to
1891 indicate the usage count of the object. The object won't be
1892 freed untill the reference counter hits zero. Currently only
1893 server uses this, and client ignores it. The client must be
1894 set to use this too later. The affected files are
1895 lib/silccore/silcsockconn.[ch]. Added also the function
1896 silc_socket_dup to increase the reference counter.
1898 This was mainly added because it is possible that the socket
1899 is removed underneath of pending command or other async
1900 operation. Now it won't be free'd and proper DISCONNECTING
1901 flags, etc. can be set to avoid sending data to connection that
1902 is not valid anymore.
1904 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1905 the connection. After that it sets SILC_SET_DISCONNECTED.
1906 It is, however, possible that the socket data is not still freed.
1907 The silc_server_packet_process now checks that data is not
1908 read or written to connection that is DISCONNECTED. The socket
1909 get's freed when the reference counter hits zero.
1911 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1913 * Changed the client operation API: channel_message operation's
1914 `sender' is now the client entry of the sender, not the nickname
1915 and the `channel' is the channel entry, not the channel name.
1917 In the private_message operation the `sender' is now also the
1918 client entry of the sender not the nickname.
1920 Affected file is lib/silcclient/ops.h and all applications
1921 using the client operations.
1923 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1925 * Moved the calling of ops->connect() from connect_to_server_final
1926 into receive_new_id functin since that is the point when the
1927 client is actually allowed to send traffic to network. The
1928 affected file is lib/silcclient/client.c.
1930 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1932 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1933 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1934 (if needs broadcasting) instead of broadcasting the packets one
1935 by one which would make a burst in the network traffic.
1937 * Added `broadcast' argument to the functions in silcd/server.[ch]
1938 silc_server_create_new_channel[_with_id] to indicate whether
1939 to send New Channel packet to primary router.
1941 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1943 * Added new function into the silcd/server.[ch] files:
1944 silc_server_create_new_channel_with_id to create new channel with
1945 already existing Channel ID.
1947 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1948 lib/silccore/silcpacket.h. This packet is used t send list of
1949 Set Mode payloads inside one packet. Server uses this to set
1950 the modes for the channels and clients on those channels, that it
1951 announced to the router when it connected to it. The protocol
1952 specification has been updated accordingly.
1954 * The silc_server_new_channel did not handle the packet coming
1955 from normal server as it normally does not send that. However,
1956 when it announces its channels it does send it. Implemented
1957 the support for that.
1959 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
1960 into the file lib/silccore/id.h.
1962 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1964 * Fixed memory leaks in the functions silc_idlist_del_client,
1965 silc_idlist_del_channel and silc_idlist_del_server in the file
1966 silcd/idlist.c. All of those leaked like a sieve.
1968 * Fixed some small memory leaks in the client's function
1969 silc_client_notify_by_server.
1971 * Added functions into silcd/server.c: silc_server_announce_clients,
1972 silc_server_announce_channels and silc_server_announce_server.
1973 These functions are used by normal and router server to announce
1974 to its primary router about clients, channels and servers (when
1975 router) that we own. This is done after we've connected to the
1978 These functions effectively implements the following packet types:
1979 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
1980 and SILC_PACKET_NEW_ID_LIST.
1982 * Added new functions into the silcd/packet_receive.[ch]:
1983 silc_server_new_id_list, silc_server_new_channel_list and
1984 silc_server_new_channel_user_list to handle the incoming
1985 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
1987 * Added support of changing Channel ID in the function
1988 silc_server_replace_id. If the server that announces a channel
1989 to the router already exists in the router (with same name but
1990 with different Channel ID), router is responsible to send
1991 Replace ID packet to the server and force the server to change
1992 the Channel ID to the one router has.
1994 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
1995 client that the Channel ID has been changed by the router. The
1996 normal server sends this to the client. Client must start using
1997 the new Channel ID as the channel's ID.
1999 Implemented handling of this new type into lib/silcclient/client.c
2000 into the function silc_client_notify_by_server.
2002 * Added new function silc_idlist_replace_channel_id into the files
2003 silcd/idlist.[ch] to replace the Channel ID.
2005 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2007 * Call silc_server_command_identify_check always when processing
2008 the IDENTIFY command in silcd/command.c
2010 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2012 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2013 send keepalive packets. The packet can be sent by clients,
2014 servers and routers.
2016 Added function silc_socket_set_heartbeat into the file
2017 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2018 If not set, the heartbeat is not performed. The actual
2019 heartbeat is implemented in the low level socket connection
2020 library. However, application is responsible of actually
2023 Added silc_server_send_heartbeat to send the actual heartbeat
2024 packet into silcd/packet_send.[ch]. Server now performs
2025 keepalive with all connections.
2027 * Added silc_task_get_first function into lib/silcutil/silctask.c
2028 to return the timeout task with shortest timeout. There was a bug
2029 in task unregistration that caused problems. TODO has been
2030 updated to include that task system must be rewritten.
2032 * The client library will now resolve the client information when
2033 receiving JOIN notify from server for client that we know but
2034 have incomplete information.
2036 * Rewrote parts of silc_server_remove_from_channels and
2037 silc_server_remove_from_one_channel as they did not remove the
2038 channel in some circumstances even though they should've.
2040 * Encryption problem encountered in server:
2042 The LEAVE command used to send the Channel Key packet to the
2043 router immediately after generating it. However, the code
2044 had earlier sent Remove Channel user packet but not immediately,
2045 ie. it was put to queue. The order of packets in the router
2046 was that Channel Key packet was first and Remove Channel User
2047 packet was second, even though they were encrypted in the
2048 reverse order. For this reason, MAC check failed. Now, this
2049 is fixed by not sending the Channel Key packet immediately but
2050 putting it to queue. However, this is more fundamental problem:
2051 packets that are in queue should actually not be encrypted
2052 because packets that are sent immediately gets encrypted
2053 actually with wrong IV (and thus MAC check fails). So, packets
2054 that are in queue should be encrypted when they are sent to
2055 the wire and not when they put to the queue.
2057 However, the problem is that the current system has not been
2058 designed to work that way. Instead, the packet is encrypted
2059 as soon as possible and left to the queue. The queue is then
2060 just purged into wire. There won't be any fixes for this
2061 any time soon. So, the current semantic for packet sending
2064 o If you send packet to remote host and do not force the send
2065 (the packet will be in queue) then all subsequent packets to the
2066 same remote host must also be put to the queue. Only after the
2067 queue has been purged is it safe again to force the packet
2070 o If you send all packets immediately then it safe to send
2071 any of subsequent packets through the queue, however, after
2072 the first packet is put to queue then any subsequent packets
2073 must also be put to the queue.
2075 Follow these rules and everything works fine.
2077 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2079 * Added new function silc_server_remove_clients_by_server to
2080 remove all client entries from ID list when the server connection
2081 is lost. In this case it is also important to invalidate all
2082 client entires as they hold the invalid server entry. This
2083 fixes fatal bug when server has lost connection and will reconnect
2086 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2088 * Made some sanity checks to silc_server_daemonise like to check
2089 whether the requested user and group actually exists.
2091 * Added sanity check to SKE's silc_ske_responder_finish to check
2092 that the public and private key actually is valid.
2094 * Invalidate the client's nickname when receiving Replace ID
2095 packet and the Client ID is being replaced. This means that the
2096 server will query the nickname if someone needs it (client)
2099 * Sort the ID Cache in client library when the ID Cache data
2100 has changed (needs sorting).
2102 * Do not allow for SILC client to create several connections to
2103 several servers. The client does not support windows right now
2104 and generating multiple connections causes weird behaviour.
2106 Irssi-silc client does support windows and can handle several
2107 connections without problems, see: www.irssi.org and SILC plugin.
2109 * Fixed some places where client was added to the IDList. The
2110 rule of thumb is following (in order to get everything right):
2111 If the client is directly connected local client then the
2112 `connection' argument must be set and `router' argument must be
2113 NULL to silc_idlist_add_client function. If the client is not
2114 directly connected client then the `router' argument must
2115 bet set and the `connection' argument must be NULL to the
2116 silc_idlist_add_client function.
2118 * The funtion silc_server_packet_send_local_channel actually did
2119 not check whether the client was locally connected or not. It
2120 does that now. Fixed a bug related to LEAVE command.
2122 * Fixed Remove Channel User payload parsing bug in server's
2123 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2125 * The server's silc_server_save_channel_key now checks also the
2126 global ID list for the channel as it might not be in the local
2127 list. Fixed a bug related to LEAVE command.
2129 * Is this the end of the [<unknown>] buglet that has been lurking
2130 around for a long time? A little for loop fix in server's
2131 silc_server_command_whois_parse that is used by both IDENTIFY
2132 and WHOIS command. At least, this was a clear bug and a cause
2133 of one type of [<unknown>] buglet.
2135 * WHOIS and IDENTIFY commands call the function
2136 silc_server_command_[whois/identify]_check function even if
2137 we are not router server.
2139 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2141 * Added --with-gmp configuration option. If set the GMP
2142 is always compiled in the SILC source tree. If not set then
2143 it is checked whether the system has the GMP3 installed. If
2144 it has then the GMP won't be compiled (the system's headers
2145 and library is used), if it doesn't have it then the GMP is
2146 compiled in the SILC source tree.
2148 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2150 * Changed RSA private exponent generation to what PKCS #1
2151 suggests. We try to find the smallest possible d by doing
2152 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2153 not security fix but optimization.
2155 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2157 * Added new config entry [Identity] to fork the server and run
2158 it as specific user and group. A patch from Bostik.
2160 * Imported Dotconf configuration library into lib/dotconf.
2161 This will be used to create the SILC configuration files later.
2162 It will appear in the distsribution after this commit.
2164 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2166 * A big code auditing weekend happening. Auditing code for
2167 obvious mistakes, bugs and errors. Also, removing any code
2170 Removed files for being obsolete:
2172 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2173 inline in the file lib/silcutil/silcbuffer.h)
2175 o lib/silcutil/silcbufutil.c (the header has inline versions)
2177 Changed code to fix possible error conditions:
2179 o The buffer formatting routines now check that the destination
2180 buffer really has enough space to add the data. This applies for
2181 both buffer formatting and unformatting
2182 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2183 unformatting was changed to accomodate following rules:
2184 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2185 sent to the function while XXX_*STRING will not allocate or copy
2186 the data into the buffer. Instead it sets the pointer from the
2187 buffer into the pointer sent as argument (XXX_*STRING used to
2188 require that the pointer must be allocated already). This change
2189 makes this whole thing a bit more consistent and more optimized
2190 (note that the data returned in the unformatting with XXX_*STRING
2191 must not be freed now). The routines return now -1 on error.
2193 o Tried to find all code that use buffer_format and buffer_unformat
2194 and added return value checking to prevent formatting and
2195 especially unformatting errors and possible subsequent fatal
2198 o Changed ske->x and ske->KEY to mallocated pointers in
2199 lib/silcske/silcske.h. Fixed possible data and memory leak.
2201 o Added return value checking to all *_parse* functions. Fixed
2202 many memory leaks as well.
2204 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2205 so that buffer overflows would not happen. All code now also
2206 checks the return value as it can fail.
2208 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2210 * Added reconnection support to server if the normal server looses
2211 its connection to the router (for example if router is rebooted).
2212 The server performs normal reconnection strategy implemented
2213 to the server. Affected file silcd/server.c.
2215 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2217 * Added new packet type SILC_PACKET_SET_MODE that is used to
2218 distribute the information about changed modes (for clients,
2219 channels and clients channel modes) to all routers in the
2220 network. Updated the protocol specification accordingly.
2222 Added functions into silcd/packet_send.c and
2223 silcd/packet_receive.c: silc_server_send_set_mode,
2224 silc_server_set_mode.
2226 Added new files silcmode.[ch] into lib/silccore that implements
2227 the encoding and decoding of Set Mode Payload. Added new type
2228 SilcSetModePayload. Moved the definitions of different modes
2229 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2231 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2233 * Oops, a little mistake in server's connection authentication
2234 protocol. The protocol is not ended with FAILURE but with
2235 SUCCESS if the authentication is Ok. :) Affected file is
2238 * Implemented NICK_CHANGE notify handling in server in the file
2239 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2240 the local clients on the channel. After the changing nickname
2241 in router environment snhould work and the [<unknown>] nickname
2242 should appear no more.
2244 The silc_server_replace_id function that receives the Replace ID
2245 payload now sends the NICK_CHANGE notify type also in the file
2246 silcd/packet_receive.c
2248 * Changed WHOIS and IDENTIFY command to support the maximum amount
2249 of arguments defined in protocol specs (3328 arguments). This
2250 fixed a bug that caused problems when there were more than three
2253 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2255 * Added extra parameter, command identifier, to the
2256 silc_client_send_command so that explicit command identifier
2259 Changed that ID list routines uses specific command identifier
2260 when sending WHOIS/IDENTIFY requests to the server so that they
2261 can be identified when the reply comes back.
2263 Affected files lib/silcclient/command.[ch],
2264 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2266 * Added `sender' argument to silc_server_packet_send_to_channel
2267 to indicaet the sender who originally sent the packet to us
2268 that we are now re-sending. Ignored if NULL. Affected file
2269 silcd/packet_send.[ch].
2271 * Added some server statistics support in silcd/server_internal.h
2272 SilcServerStatistics structure and around the server code. Also
2273 send some nice statistics information when client is connecting
2276 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2278 * Fixed channel ID decoding in server's JOIN command reply in
2279 silcd/command_reply.c
2281 * Fixed braodcasting of replace ID payload to not to send it if
2282 we are standalone server in silcd/packet_receive.c.
2284 * Fixed all channel message sending routines to not to send
2285 packets to clients that has router set, since they are routed
2286 separately in the same function earlier. Affects file
2287 silcd/packet_send.c and all channel packet sending functions.
2289 * In USERS reply, res_argv[i] are not allocated, the table
2290 is allocated. Thus changed that free the table, not its
2293 * In server's whois_check and identify_check if the client is
2294 locally connected do not send any WHOIS commands - they are not
2297 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2299 * Fixed some minor bugs in client when sending WHOIS command. The
2300 arguments was in wrong order.
2302 * Removed statis function add_to_channel from server in
2303 silcd/command.c that was previously used with the joining but
2306 * Tested USERS command in router environment successfully with two
2307 routers, two servers and two clients.
2309 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2311 * Reorganized the USERS command and command reply in client library
2312 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2313 When the command is given by user we register a pending command
2314 callback that will reprocess the command after the reply has been
2315 received from the server. When reprocessing the packet we then
2316 display the information. Thus, the USERS information is displayed
2317 now in the command callback instead of in the command reply
2318 callback. The processing of the command is same as previously
2319 when server has sent the command reply in the JOINing process.
2321 * Added to USERS command in silcd/command_reply.c to join the client,
2322 we didn't use to know about, to the channel after we've created
2323 a client entry for it. Also, for clienet we did know already still
2324 check whether it is on the channel or not and add it if not.
2326 * Removed silc_server_command_join_notify as the function and its
2329 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2331 * Changed the client's pending command handling to the same as the
2332 server's pending command handling. It is also now possible to
2333 execute command reply functions from other command reply
2334 function as the function callbacks for commands and command
2335 replies are one and same. The pending commands are not static
2336 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2337 in client connection context. Thus, pending commands are server
2338 connection specific as it is convenient.
2340 Changed the function silc_client_command_pending and
2341 silc_client_command_pending_del and added new function
2342 silc_client_command_pending_check. Removed the
2343 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2346 * Added cmd_ident, current command identifier, to the client
2347 connection context in lib/silcclient/client.h to keep track on
2348 command identifiers used in command sending. Client's command reply
2349 function handling now supports the mandatory command identifiers.
2351 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2352 funtions in client to fully support pending command callbacks.
2354 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2355 as one of the arguments to the application in the command reply
2358 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2359 before first releasing SILC but came back. Now it is removed again
2360 and should come back nomore. The FORWARDED flag was used only
2361 by the JOINing procedure by forwarding the command packet to router.
2362 Now, the JOINing procedure has been changed to more generic (due
2363 to various router environment issues) and FORWARDED is not needed
2364 anymore for anything. The protocol specification is yet to be
2367 Now, removed silc_server_packet_forward from server and the flag
2368 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2370 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2372 * Renamed NAMES command to USERS command. The NAMES was named that
2373 due to historical reasons. Now it is renamed. Also, rewrote
2374 parts of the USERS command. The nickname list is not sent anymore
2375 by the server. Only Client ID and mode lists are sent in the USERS
2376 command. Changed this also to the protocol specification.
2378 The client now resolves the names and stuff after it receives
2379 the USERS list from the server when joining to the channel.
2381 * WHOIS and IDENTIFY commands has been changed to support multiple
2382 Client ID's per command. One can now search for multiple users
2383 in the network by sending only one WHOIS or IDENTIFY command.
2384 Changed the code and the protocol specifications.
2386 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2387 uses silc_server_command_whois_parse to parse the request. */
2389 * If normal server, do not parse the WHOIS and IDENTIFY requests
2390 before sending it to the router. Saves some time.
2392 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2394 * Fixed JOIN command on client library. Wrong number of arguments
2395 used to crash the client.
2397 * Added silc_server_channel_has_global function to check whether
2398 channel has global users or not.
2400 * Added silc_server_channel_has_local function to check whether channel
2401 has locally connected clients on the channel.
2403 * The silc_server_remove_from_one_channel now checks whether the
2404 channel has global users or not after given client was removed from
2405 the channel. It also checks whether the channel has local clients
2406 on the channel anymore. If it does not have then the channel entry
2407 is removed as it is not needed anymore.
2409 * The silc_server_notify now checks on JOIN notify whether the joining
2410 client is one of locally connected or global. If it is global then
2411 the channel has now global users on the channel and that is marked
2412 to the channel entry. Also, it now saves the global client to
2413 global list who is joining and JOINs it to the channel. This is
2414 for normal server, that is.
2416 Changed silc_server_send_notify_on_channel,
2417 silc_server_packet_relay_to_channel and
2418 silc_server_packet_send_to_channel check if we are normal server
2419 and client has router set (ie. global client) do not send the
2420 message to that client, as it is already routed to our router.
2422 * Implemented LEAVE notify type handling in silc_server_notify
2425 * Tested LEAVE command in router environment successfully. Tested
2426 with two routers, two servers and two clients.
2430 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2432 * Implemented SIGNOFF notify type handling in silc_server_notify
2435 * silc_server_remove_id now removes the client entry from all channels
2436 it has joined and thusly sends SIGNOFF notify type.
2438 * Rewrote the NAMES list generation in server by removing two excess
2439 loops. The lists are created now inside one loop.
2441 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2443 * silc_server_remove_channel_user checks now also global list
2444 for channel and client.
2446 * silc_server_new_channel_user checks now both local and global
2447 list for channel and client. Fixed a bug in client id decoding.
2448 Used to decode wrong buffer.
2450 * silc_server_channel_message checks now both local and global
2451 list for channel entry.
2453 * Tested channel joining (hence JOIN) in router environment
2454 successfully. Tested with two routers, two servers and two
2457 * Tested channel message sending in router environment successfully.
2459 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2461 * Added silc_server_save_channel_key into server.[ch] to save the
2462 received channel key in Channel Key payload processing. It is
2463 also used in JOIN command reply handling.
2465 Equivalent function silc_client_save_channel_key added into
2466 client.[ch] into client library.
2468 * Changed JOIN command reply to send information whether the channel
2469 was created or not (is existing already) and the channel key
2470 payload. Changed protocol specs accordingly.
2472 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2473 the request was sent by ID and not by nickname. Crashed on
2476 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2478 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2479 now correctly save the received data.
2481 * silc_server_free_sock_user_data now notifies routers in the
2482 network about entities leaving the network.
2484 At the same time implemented functions silc_server_remove_id
2485 and silc_server_send_remove_id to receive and send REMOVE_ID
2486 packets. The packet is used to notify routers in the network
2487 about leaving entities. The ID removed will become invalid in
2490 * Added function silc_idlist_del_server into server. Removes and
2491 free's server entry from ID list.
2493 * silc_server_private_message function now checks, if we are router,
2494 that the destination ID really is valid ID, naturally.
2496 * In router when NEW_ID packet is received (for new client) the
2497 hash of the Client ID is saved in the ID Cache but the
2498 client->nickname is set to NULL, instead of putting the hash
2501 IDENTIFY command now also checks that client->nickname must be
2502 valid. If it is not if will request the data from the server who
2503 owns the client. Added new function
2504 silc_server_command_identify_check.
2506 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2507 to set the command to already allocated Command Payload.
2509 * Tested private message sending in router environment with two
2510 routers, two servers and two clients. Fixed minor bugs and now
2513 * Fixed segfault from client's NAMES command. Used to crash if
2516 * Forwarded packets must not be routed even if it is not destined
2517 to the receiver. Changed server code comply with this.
2519 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2521 * Added `require_reverse_mapping' boolean value to ServerParams
2522 structure. If TRUE (not default) the server will require that
2523 the connecting host has fully qualified domain name.
2525 If the reverse mapping is not required and hostname could not be
2526 found the IP address is used as hostname.
2528 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2530 * Implemented version string checking to both client and server.
2531 The check is incomplete currently due to the abnormal version
2532 strings used in development version of SILC.
2534 * Changed all command functions in server to use the new
2537 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2539 * Changed char *data to unsigned char *data in ID Cache system to
2540 support binary data as ID Cache data. Changed code to support
2541 binary data in lib/silccore/idcache.c.
2543 * Renamed silc_server_packet_relay_command_reply to
2544 silc_server_command_reply as it is normal packet receiving
2545 function. Rewrote the function to accept command replys for
2546 servers and not only for clients.
2548 * Mark remote router always as registered server if we are connecting
2549 to it. Otherwise, commands sent by the router to us are ignored.
2551 * All ID List find routines now returns the ID Cache Entry pointer
2552 as well if requested.
2554 * WHOIS command works now in router environment, tested with two
2555 routers, two servers and two clients.
2557 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2558 in router environment (as it is almost equivalent to WHOIS) but
2559 hasn't been tested thoroughly. Added new functions:
2561 silc_server_command_identify_parse
2562 silc_server_command_identify_send_reply
2563 silc_server_command_identify_from_client
2564 silc_server_command_identify_from_server
2566 * Disabled route cache adding because adding two different ID's with
2567 same IP replaces the old cache entry thus giving wrong route.
2568 The entry->router->connection is always the fastest route anyway
2569 so route cache may not be needed. Of course, new routes maybe
2570 established after receiving the ID when the entry->router->connection
2571 might not be anymore the most optimal.
2573 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2575 * Add route cache for received ID for fast routing.
2577 * Added silc_server_packet_route to route received packet on router
2578 that is not destined to us.
2580 * Renamed silc_server_get_route to silc_server_route_get.
2582 * Added id_string and id_string_len fields into SilcServer to
2583 include encoded ServerID for fast comparing without excess
2584 encoding of the ID's.
2586 * Cleaned up WHOIS command on server side. Added following static
2589 silc_server_command_whois_parse
2590 silc_server_command_whois_check
2591 silc_server_command_whois_send_reply
2592 silc_server_command_whois_from_client
2593 silc_server_command_whois_from_server
2595 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2596 arguments in command replies. All command functions should be
2597 updated to use this macro.
2599 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2601 * Minor typo fixes on command reply handling on server.
2603 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2605 * Added silc_server_command_add_to_channel internal routine to add
2606 the client to the channel after router has created the channel and
2607 sent command reply to the server.
2609 * Added generic silc_server_send_command to send any command from
2612 * Use static buffer with ID rendering instead of duplicating data.
2614 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2616 * Fixed a channel user mode bug when joining to a channel server gave
2617 everybody channel founder rights, oops.
2619 * We mark ourselves as the router of the incoming server connection
2620 if we are router ourselves. This way we can check in some packet
2621 sending functions whether it is locally connected server. For
2622 incoming router connections we put NULL.
2624 * For router sending packets locally means now always sending the
2625 packet cell wide; to local clients and local servers. For normal
2626 server sending packet locally means sending it to only local
2629 * Fixed the JOIN command to really work in router environment. If the
2630 channel is created it is always created by the router. Router is
2631 also responsible of making the initial joining to the channel,
2632 sending JOIN notify to the sending server and distributing
2633 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2634 does not exist server doesn't do anything else but forward the
2635 command to the router which performs everything.
2637 * Added silc_server_send_channel_key function to send the Channel Key
2640 * Added silc_server_create_channel_key to create new channel key. The
2641 channel key is now re-generated everytime someone joins or leaves
2642 a channel, as protocol dictates. Note: channel->key_len is the
2645 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2647 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2648 packet_receive.[ch] to separate packet sending and receiving
2649 routines. The server.[ch] now includes everything else including
2650 actual packet processing (writing and reading data) and other
2653 Renamed silc_server_private_message_send_internal to
2654 silc_server_send_private_message. The routine is still though
2655 used only to relay private messages as server does not send
2656 private messages itself.
2658 Renamed silc_server_new_channel to silc_server_create_new_channel
2659 and added new function sicl_server_new_channel that handles the
2660 incoming New Channel packet. Added also new sending function
2661 silc_server_send_new_channel to send New Channel Payload.
2663 * Added new function silc_server_notify to process incoming notify
2664 packet to the server/router. Server may then relay the notify
2665 to clients if needed.
2667 * Added new function silc_server_new_channel_user to process incoming
2668 New Channel User packet. Router will redistribute the packet and
2669 send JOIN notify to its local clients and locally connected servers
2670 if needed. Normal server will send JOIN notify to its local client
2671 on same channel when received this packet. Added also corresponding
2672 sending function silc_server_send_new_channel_user to sent the
2675 * Added boolean route argument to send_notif_to_channel and
2676 packet_send_to_channel functions to attempt to route the packet
2677 if it is TRUE and send only locally if it is FALSE.
2679 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2681 * silc_server_replace_id now broadcasts the received replace ID
2682 packet if it is not broadcast packet already. The router must
2683 broadcast to inform other routers about changed ID.
2685 * Added backpointer to server's router into SilcServer context in
2686 silcd/server_internal.h.
2688 * Fixed silc_server_packet_broadcast to send correct broadcast
2691 * The channel key is now distributed to the local client as soon
2692 as it is received from the router (in router environment) so that
2693 no other packet may be sent for the channel until client has
2696 * silc_server_remove_channel_user now broadcasts the received
2697 Remove Channel User packet if it is not broadcast packet already.
2698 The router must broadcast to inform other routers about removed
2701 * Added users field into SilcPacketContext that is a reference count
2702 of the context. One can increase the reference count by calling
2703 silc_packet_context_dup which is now changed to just increase the
2704 reference count instead of duplicating the data. The reference
2705 count is decresed by calling silc_packet_context_free that will
2706 free the data after the reference count hits zero.
2708 For now on the packet context and everything allocated into it
2709 (including the raw packet from network) must be freed by calling
2710 the new silc_packet_context_free function. Added also new function
2711 silc_packet_context_alloc that must be used now to allocate the
2712 context. This also means that if a routine is asynchronous from
2713 silc_[client/server]_packet_parse_type the packet context must
2714 be duplicated by calling silc_packet_context_dup. Otherwise it
2715 gets free'd after silc_[client/server]_packet_parse_type returns.
2716 Also, one must remember that if packet is duplicated then its
2717 reference count must be decresed by calling the free function as
2718 many times as it was duplicated.
2720 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2721 from both client and server.
2723 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2725 * Made joining to a channel working in router environment.
2727 * Cleaned up JOIN command on server side and create function
2728 silc_server_command_join_channel internal routine to make the
2731 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2733 * Changed silc_command_pending list to SilcDList. Also, added
2734 `ident' field to SilcServerCommandPending structure to identify
2735 the reply and to call correct callback.
2737 Added silc_server_command_pending_check function to replace the
2738 corresnponding macro. The silc_command_pending list is not
2741 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2742 to set identifier to previously allocated Command Payload. It
2743 is used to set identifier for command when resending Command
2746 * Added silc_command_payload_encode_payload to encode Command
2747 Payload buffer from SilcCommandPayload structure.
2749 * Added silc_argument_payload_encode_payload to encode Argument
2750 payload buffer from SilcArgumentPayload structure.
2752 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2754 * Changed WHOIS command to support router connection on server side.
2755 The whois request is always sent to router unless the server is
2756 standalone server. After server has received the reply from the
2757 router will it send the reply to the client.
2759 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2760 broadcast received broadcast packet. The function is used only
2761 by router. The broadcast packet is always sent to the router's
2764 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2765 render given ID to printable string, for log files for example.
2767 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2769 * Made basic router to router connections working. At least they
2770 can now connect to each other but nothing really works the way
2771 they are supposed - yet.
2773 * Added new initiator token to RouterConnection configuration
2774 file in silcd/serverconfig.[ch]. It is used to tell whether we
2775 are the initiator to the remote router or whether we'll expect
2776 the other end to connect.
2778 * Moved registering of listener task to silc_server_init, hence
2779 the server starts listenning as soon as it is run, even if it
2780 does not have connections to other routers. Let's see how well
2783 * Changed default connection retry timeouts for more suitable in
2786 * Removed cipher and such arguments from silc_idlist_add_client
2787 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2788 Added new function silc_idlist_add_data to add the keys and stuff
2791 * Added SilcIDListData structure and added it to SilcClientEntry
2792 and SilcServerEntry as their first field in the structure. This
2793 way we can explicitly cast the ID entries to the SilcIDListData
2794 structure and get common data for the entries. In past, we had
2795 to first check what type of connection it is and then cast it to
2796 correct ID entry type. Now, we can directly cast the opaque
2797 pointer to the SilcIDListData (no matter what ID entry it actually
2798 is) and get the data needed.
2800 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2802 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2803 in some circumstances even if threre were timeout tasks, though not
2804 IO tasks, but tasks anyway. Now fixed.
2806 * Defined SilcServerConnection structure to hold connection specific
2807 stuff about directly connected servers and routers. The definition
2808 is currently in silcd/server_internal.h. I thought about having
2809 a bit more important role fro this struct but for now it is used
2810 only when connecting to other server (or router actually).
2812 * Added connecting retry support in server when connecting to
2813 router(s). The retry feature implement exponential backoff
2814 algorithm. Also, added SilcServerParams structure to hold default
2815 parameters for server. For now, it include these retry settings
2816 and are hard coded. After server is moded to be as Silc Server
2817 Library this structure will be more important.
2819 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2821 * Changed client librarys channel->clients table to SilcList and
2822 changed code accordingly.
2824 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2826 * Changed client's channel table to SilcList and changed code
2827 accordingly. Also changed SilcChannelClientEntry to include back-
2828 pointer to the channel so that client entry can use that structure
2829 as list as well and we have fast cross-reference to the channel.
2830 This change dramatically decreased the complexity of channel
2831 handling with client entry and vice versa (removed one extra
2832 loop when searching for channel entry from many functions).
2834 * Changed server->sim from table to SilcDList and changed code
2837 * NAMES command can now be used from user interface. It will show
2838 the user list on the channel, neatly.
2840 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2841 Code now saves realname of the user if it becomes available.
2843 * Renamed configure.in to configure.in.pre and made ./prepare
2844 script to automatically add correct version string to
2845 configure.in which it creates from configure.in.pre.
2847 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2849 * NAMES command reply now shows users mode with the nickname when
2852 * Moved silc_client_ch[u]mode[_char] functions from
2853 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2854 place sucks, they are utility functions and should be in some
2857 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2859 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2862 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2866 * Added TRQ (efficient deque and list library) into lib/trq. This is
2867 a very good list library that is currently used in the SILC. Defined
2868 SilcList API over the library because I didn't like the API very
2869 much. See lib/trq/silclist.h for the API and examples of how to
2870 use the API. Fixed various places in the code to use the new
2871 SilcList API. The SilcList is meant for lists that has a structure
2872 already defined as a list. It is not suitable to add just some
2873 context to the list (in TRQ, the context is the list actually).
2875 So, I defined SilcDList that can be used for the purpose where
2876 predefined list structure does not exit. This can be used as
2877 such list. Now some context just can be added to the SilcDList.
2878 Currently this list is not used in the SILC just yet, though there
2879 are a lot places where this can replace dynamically allocated
2880 tables and I will fix these places, later, to use SilcDList.
2881 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2882 and use TRQ internally).
2884 Also fixed some annoying warning messages that the original TRQ
2885 code generated. Also minor changes to TRQ's Makefile.in.
2887 * Added support for querying by Client ID to both WHOIS and
2888 IDENTIFY commands into server, as required by the protocol.
2890 * Removed method function pointers from SilcBuffer structure. They
2891 weren't used to anything and just increased the context size for
2892 no good reason. This change also made silc_buffer_alloc and
2893 silc_buffer_free functions inline functions.
2895 * Disabled command flooding detection support until it's fixed so
2896 that it accepts commands in but does not execute them more than once
2899 * Added silc_net_localhost(), to return local hostname, into
2900 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2901 that must be initialized before calling silc_client_init.
2903 * Added new function: silc_server_send_notify_on_channels to send
2904 notify messages to all channels client has joined. It is assured
2905 that the message is sent only once per client.
2907 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2908 lib/silcutil/silcutil.[ch] as silc_format function. The new
2909 function is generic and is used by server as well, not only by
2910 the logging routines.
2912 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2913 the provided version string was not acceptable. Added new function:
2914 silc_ske_check_version into lib/silcske/silcske.h. The function
2915 must be implemented by the application (client or server) and it
2916 does not reside in the SKE library. The function checks the version
2917 string remote end sent.
2919 * Added back pointers (to opaque context and to SilcSocketConnection)
2920 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2922 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2923 duplicate packet context structure.
2925 * Changed `notify' client operation to send same arguments as client
2926 receives from server except for ID's. ID's are mapped to correct
2927 ID entry and that is returned. Also, if channel entry is not sent
2928 by server but the notify is for channel the channel entry is sent
2929 to application (otherwise application doesn't know that it is for
2930 channel (library gets it from packet's Destination ID)).
2932 * Added silc_client_remove_from_channels into client library to
2933 remove a client from all channels it has joined to. Used when
2934 received SIGNOFF notify from server. Added also new function
2935 silc_client_replace_from_channels to replace old ID entry with
2936 new ID entry on all channels. Used when received NICK_CHANGE
2939 * Fixed ID Cache list handling in silc_idlist_get_client in
2940 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2941 to get (or query) client by ID.
2943 * Updated TODO list.
2945 * Added connection authentication status message defined by the
2946 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2947 support for these into the code in client and server side.
2949 * Added generic function silc_client_send_command to send any command
2950 with variable argument list. Application should use this function
2951 to send commands if the command functions provided by the library
2952 does not suite for the application's user interface needs.
2954 * Added new `failure' client operation. Application is notified about
2955 received failure packet if client is executing a protocol. In this
2956 case the protocol's execution has failed.
2958 * Added SKE's end notify to send the SKE_SUCCESS notify message that
2959 is required by the protocol.
2961 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
2962 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
2965 * Added status flag to SilcSKE object to indicate realtime status
2966 of the SKE protocol.
2968 * Application receives now exactly same command reply arguments as
2969 the library receives from server. However, if ID is received the
2970 corresponding ID entry is returned to the application (eg. Client
2971 ID is mapped to correct SilcClientEntry entry and that is returned).
2972 Changed command_reply client operation due to this change.
2974 * Changed all ID's in commands and in command replys as ID Payloads.
2975 Change affected both client and server side codes.
2977 All ID's sent in SILC network (with execption of ID's in SILC
2978 Packet header) are sent in ID Payload to support variable length
2981 * Server now notifies nick changes and notifies all clients on
2982 the channels about the new nickname (about the new Client ID,
2985 * Implemented CMODE command to change channel modes. Supports all
2986 channel modes defined by the protocol specs except ban and invite
2987 lists. (Also, private channel key mode is supported but support for
2988 setting private channel key in client is missing, thus, this mode
2989 has no effect on client side (except that server requires that the
2990 client uses private channel key and normal channel traffic does not
2993 Also, invite mode works per se, but INVITE command does not work
2994 yet correctly, so you can set channel as invite only channel but
2995 inviting clients to the channel does not work (it is yet to be
2996 thought what's the best way to do it).
2998 * Added new command SILC_COMMAND_CUMODE to change user mode on the
2999 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3000 Implemented CUMODE command to change user's mode on the channel.
3001 Supports all modes defined by the protocol specs.
3003 * Added NAMES command reply to return users modes on the channel.
3005 * Removed unnecessary and slow ciphers from lib/silccrypt.
3007 * Set SO_KEEPALIVE option to connection sockets by default.
3009 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3011 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3012 redefined the Notify Payload into protocol specs.
3014 * Added silc_id_payload_parse_id to get ID directly from raw
3017 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3019 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3020 accept searching by Client ID as well.
3022 * Added support for LEAVE and SIGNOFF notify types in client library.
3024 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3025 to parse ID Payload from raw data.
3027 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3029 * Added flags parameter into silc_ske_assemble_security_properties
3030 function in lib/silcske/silcske.[ch].
3032 * Changed notify client operation to fit better for notify messages
3033 sent by server. The notify payload received from server is now
3034 passed to the application (after parsing it to SilcNotifyPayload).
3035 It is application's responsibility to retrieve the arguments
3036 from the payload and show the message the way it wants. The message
3037 sent by server is implementation specific.
3039 * Changed public keys to comply with the protocol specification.
3040 Old public keys are not supported anymore and are not compatible.
3042 * Removed nickname from Channel Payload as the latest draft removed
3043 it. The client must resolve the nickname from the NAMES command
3044 reply received when it joined the channel.
3046 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3048 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3050 * Fixed some errors in protocol specification drafts.
3052 * Created lib/silccore/silcnotify.c to implement Notify Payload
3053 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3054 generic payloads described by protocol specifications. The file
3055 includes implementations for ID Payload and Argument Payload.
3057 * Changed Command Payload implementation to use the new Argument
3058 Payload. Changed command_xxxx_payload to command_payload_xxxx
3059 to comply with SILC coding conventions.
3061 * Added suppport for Argument Payload handling in Notify Payload
3062 implementation as protocol requires it. Added the new support
3063 into server and client lib as well.
3065 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3067 * Added support for multiple nicknames on same channel. [n] is
3068 added locally to the nickname if there are more than one same
3069 nicknames on the channel.
3071 * Server now sends all nicknames that matched WHOIS request.
3072 Client also shows the list received from server.
3074 * Added TOPIC command to client side. User can now set and show
3075 current topic on channel.
3077 * Added MOTD command to client and server. Also, server sends the
3078 motd when client connects to the server.
3080 * Changed version strings to comply ISO 8601.
3082 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3084 * Fixed protocol error handling in client library. It should now
3085 cope even if the SKE fails for some reason.
3087 * Made new protocol specification drafts for submitting to IETF.
3089 * Implemented TOPIC command to server in silcd/command.c.
3091 * Added two new notify types into lib/silccore/silcnotify.h:
3092 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3093 notify nickname change and topic setting/change on a channel.
3095 * API change of command_reply operation in client library. The
3096 application gets now the status type received from server as well.
3098 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3100 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3102 * Cras fixed and optimized the packet handling even further and
3103 it should work now. Minor change to the prototype of function
3104 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3106 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3108 * Added new function into lib/silcutil/silcschedule.[ch]:
3109 silc_schedule_with_fd to select() a specified fd. The function
3110 returns after timeout expires or data arrives or goes. The
3111 function is used by packet routines to wait that all data is
3112 received from network.
3114 * Fixed data reading from network in lib/silccore/silcpacket.c.
3115 The code now assures that all data is read from the fd and then
3116 continues packet processing. This was a bug fix since the code
3117 used to drop some data in some circumstances.
3119 * Added new function into lib/silcclient/client.[ch]:
3120 silc_client_start_key_exchange to start key exchange after
3121 connection has been established to server. The code internally
3122 now uses this funtion but its main purpose was to provide it
3123 for applications that perform their own connecting. After
3124 application has created a connection it merely calls this
3125 function to start the key exchange between client and server.
3126 The library takes care of everything else after that.
3128 Updated also lib/silcclient/README to explain the usage of
3131 * Do not send to application information that connection has
3132 been established. Application gets notified it by connect
3135 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * Applied cras's patch to add silc_schedule_one function. The
3138 function runs scheduler once and returns.
3140 * Fixed the scheduler after cras messed it up. The timeout
3141 handling works now as it's supposed to work.
3143 * Added into lib/silccore/ silcnotify.h to include notify
3144 message types support. Changed silc_server_send_notify*
3145 functions, in server.[ch], to support those new notify types.
3146 Added the support for the notify types into client library,
3147 as well. Added new notify client operation into ops.h in
3150 * Changed silc_server_packet_send_to_channel to send normal
3151 packets instead of just channel message packets. The function
3152 is now used to send the notify packets to channels. It is not
3153 used to send channel message packets anymore, as server never
3156 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3157 va_arg()s as it seems to require it nowadays. I guess, if SILC
3158 is compiled with older va_arg() the new code should work anyway.
3160 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3162 * Splitted core library. Core library (lib/silccore) includes
3163 now only SILC protocol specific core (and common) components.
3164 Created new utility library (lib/silcutil) that includes more
3165 generic purpose stuff. The stuff for util library was taken
3166 from the old core library. This was minor and easy split.
3168 * Created SILC Client Library (lib/silcclient) that includes
3169 implementation of the SILC client without user interface. This
3170 was major move from silc/ directory. The code has been changed
3171 so that it is transparent towards the user interface. The
3172 silc/ directory includes now the same user interface as before
3173 and it uses the new client library. Read lib/silcclient/README.
3174 Basicly, the client library performs everything else related
3175 to SILC except user interface handling. Also, configuration
3176 files are considered to be part of user interface and library
3177 does not handle them.
3179 This change also changed a lot of structures, function naming etc.
3180 Most important change was that SilcClientWindow object was
3181 renamed to SilcClientConnection in the client library. Created
3182 also new file lib/silcclient/ops.h. Also added new files
3183 silc/local_command.[ch] and silc/client_ops.[ch].
3185 All these changes were made to make it easier for user interface
3186 designers to create what ever user interface for the SILC client
3189 It is also expected that the server will be moved to lib
3190 directory as well and SILC Server Library will be created;
3191 sometimes in the future.
3193 * Removed Local commands from lib/silccore/silccommand.h as
3194 they are application specific and new client library does not
3195 handle any of those anymore.
3197 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3198 old client implementation in silc/.
3200 * Added support for callback functions in SILC_LOG_* macros.
3201 Application can now set its own callbacks that will be called
3202 instead of using the default functions that will always print
3203 the debug messages to stderr (or stdout). Also, debugging can
3204 now be disabled by setting silc_debug to FALSE and re-enabled by
3205 setting it to TRUE. Note, that logging will still work even
3206 if debugging is disabled.
3208 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3209 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3210 silc_log_reset_debug_callbacks.
3212 * To enable debugging in silc client one must give now -d
3213 option on command line.
3215 * Changed silc_schedule_init to automatically allocate task queues
3216 if they are not allocated before calling it.
3218 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3220 * Added GMP 3.1 into math library.
3222 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3224 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3225 a channel in SILC network. The packet is used by servers and
3226 routers to notify other routers that user has left a channel.
3227 This little feature was missing until now. Added the feature
3228 to protocol specification as well.
3230 Added functions: silc_server_send_remove_channel_user and
3231 silc_server_remove_channel_user into server.[ch].
3233 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3234 lib/silccore/silcpacket.h. However, they are not implemented
3237 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3239 * Fixed joining to a channel and sending channel messages
3240 between server and router. The channel message sending should
3241 now work inside a cell.
3243 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3245 * Fixed the private message sending between server and router.
3246 The private message sending should now work inside a cell.
3248 * Added silc_server_replace_id into server.[ch] to replace
3249 existing ID in the SILC network.
3251 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3252 and silc_idlist_replace_server_id into idlist.[ch] in server.
3254 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3256 * Fixed the server to server connections. Server can again now
3257 connect to router. Router to router connections probably does
3260 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3262 * Added dynamic protocol registering support. Now protocols can
3263 registered and unregistered on the fly. Patch by cras.
3265 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * Added lib/contrib directory to hold routines that some platforms
3268 don't have but are needed by SILC.
3270 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3271 into lin/contrib to provide getopt() and getopt_long() for
3272 those who don't have it.
3274 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3276 * Added AWAY command to client. When away message is set and
3277 client receives a private message packet the client automatically
3278 replies to the sender with the away message.
3280 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3281 bug seemed to be the cause of recent problems when compiling
3284 * Added version detection support to SKE protocol specification
3285 and added the new changes to the SKE implementation as well.
3286 There were other minor changes in the SKE protocol as well.
3288 Many changes in lib/silcske/silcske.[ch] and in
3289 lib/silcske/payload.[ch].
3291 * Added ^U functionality, clear input line. Patch from cras.
3293 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3295 * Mainly small bugfixes on core library. Fixed some debugging
3296 logging and buffer overflow in silclog.c.
3298 * Updated config.sub and config.guess on the distribution tree.
3300 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Added command lagging support in server. Client may execute
3303 commands now only once in two seconds.
3305 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3307 * Optimized packet reception. MAC computation and checking is now
3308 also more optimized. A lot previously duplicated code is now
3309 used as generic by both client and server.
3311 * Fixed key pair generation in clientutil.c
3313 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3315 * Added into lib/silccore/silcbufutil.[ch] new function;
3316 silc_buffer_realloc.
3318 * Moved generic packet sending/encryption functions to
3319 lib/silccore/silcpacket.[ch] from client and server. Some
3320 rewriting of the functions.
3322 * Moved all generic packet reception/decryption functions to
3323 lib/silccore/silcpacket.[ch] from client and server. The
3324 packet processing is now much cleaner in both client and server.
3325 These were major changes in both client and server.
3327 * Created many common functions in server to do packet sending.
3328 Previously code were duplicated a lot, this has been removed
3331 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3333 * Rewrote major parts of the ID cache system. Don't know
3334 whether it is better now or not but at least the API is more
3337 * Major rewrite on ID cache stuff on client because of the ID
3338 cache API changes. Added idlist.c to client.
3340 * Also major rewrite on ID cache stuff on server as well.
3341 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3342 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3343 in hand, instead they are all put into the ID cache system now.
3344 All server_idlist_* routines uses ID cache now instead of
3345 traversing its own lists (those lists does not exist anymore).
3346 SilcIDList though still exists. Also, SilcXXXEntry's are

3351 * Finally made the SKE implementation compliant to the protocol
3352 specification. All mp integers are now binary encoded as
3353 opposed being HEX encoded.
3355 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3358 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3359 functions: silc_[encode/decode]_pem. Also added function
3360 silc_encode_pem_file to PEM encode with newlines ('\n') for
3363 * SILC public keys are now encoded either PEM or binary. Same
3364 option is for private keys as well. By default private keys
3365 are binary encoded and public keys PEM encoded. Silly HEX
3366 encoding were removed.
3368 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3369 function to create fingerprints.
3371 * Fixed a bug in SHA1; does not change the original data anymore.
3373 * Partly implemented INFO command on client and server side.
3374 Fixed CLEAR command. Changes to SERVER command; show current
3375 server(s) when giving command without arguments. Added
3376 VERSION command to client.
3378 * Added check to server that unregistered connections cannot
3379 execute commands (unless it is specificly allowed).
3381 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3383 * Fixed screen refresh.
3385 * Fixed channel joining bug from client. On some circumstances
3386 client tried to join to a channel it had already joined.
3388 * Added public key verification process into client's protocol.c.
3389 The client now verifies the public key from user and saves
3390 it into ~./silc/serverkeys/ directory.
3392 Added into: clientutil.[ch]: silc_client_verify_server_key.
3394 * Changed SKE protocol's silc_ske_initiator_finish function
3395 to accept callback function that verifies the received public
3396 key. Removed old silc_ske_verify_public_key function.
3398 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3400 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3401 silc_pkcs_private_key[_data]_set.
3403 * Made the password and public authentication more cleaner in
3404 server's protocol.c.
3406 * Removed historic and obsolete protocol `channel_auth' from
3407 both client and server.
3409 * Removed wrong way of sending command status messages from
3410 server to client in server's command.c. The old way violated
3411 protocol specification.
3413 Changes to silccore/silccommand.[ch]: removed
3414 silc_command_encode_status_payload -> not needed anymore,
3415 changed silc_command_encode_payload_va to accept extra
3416 argument on variable argument list. The argument type must
3417 now be provided to the function. Also, added new function:
3418 silc_command_encode_reply_payload_va which is same as
3419 normal command_encode_payload_va except command status type
3420 is provided as extra argument.
3422 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3424 * Added ~./silc directory handling. The directory includes the
3425 public and private keys for the client.
3427 Added silc_client_check_silc_dir, silc_client_create_identifier
3428 and silc_client_load_keys.
3430 * Implemented SILC protocol compliant public key. Added public
3431 and private key saving to and loading from files.
3433 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3434 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3435 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3436 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3437 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3439 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3440 silc_pkcs_load_[public/private]_key.
3442 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3444 * Added silc_server_get_route (route.[ch]) to get connection
3445 data for the fastest route for given ID.
3447 * Implemented INVITE command on client and server. The command
3448 were re-defined in the SILC Protocol Specification and the
3449 implementation now complies with the specification.
3451 * Implemented PING command on client and server.
3453 * Implemented NAMES command on client and server. The server side
3454 supports currently only normal server not router server yet.
3455 Some changes to NAMES definition in SILC protocol specification.
3457 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3459 * Implemented LEAVE command on client and server.
3461 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3462 again. This change was made to the protocol as well. Server
3463 should not violate the protocol specification anymore.
3465 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3467 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3468 was tested. SOCKS4 was not but should work anyway.
