3 * Do not compile anything in lib/silcsim/* if the SIM support
4 is not enabled. The tree should now compile without problems
7 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
9 * Compiled the SILC under cygwin. Compiled and tested briefly
10 without problems. More tests needed. The SIMs didn't compile
13 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
15 * Fixed possible crash in silc_get_username in the
16 lib/silcutil/silcutil.c.
18 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
20 * Fixed a va_arg in silc/client_ops.c.
22 * Oops, RC5 routines were named AES and caused some problems
23 when not using SIM's. Affected file lib/silccrypt/rc5.c.
25 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
27 * Added new SilcIDIP structure into the lib/silccore/id.h and
28 replaced the old `ip' fields from all SILC ID's to that type.
29 This is a step towards IPv6 support.
31 The silc_id_get_len takes now the ID as an extra argument.
32 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
33 both IPv4 and IPv6 based ID's.
35 The affected files are lib/silccore/id.[ch] and other files
36 around the tree using these routines.
38 * Removed the ID length arguments in server from various
39 silc_server_send_notify_* routines -> they are not needed
42 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
44 * Fixed memory leak in silc_encode_pem_file in the file
45 lib/silcutil/silcutil.c.
47 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
49 * Check minor version as well in the SKE. Affected files are
50 silcd/protocol.c and lib/silcclient/protocol.c.
52 * Added --identifier option to the server so that an identifier
53 can be when creating the public key for the server. Affected
54 file is silcd/silcd.c.
56 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
57 lib/silccrypt/silcpkcs.c.
59 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
61 * Register default ciphers and stuff when using -C option with
62 the server. Affected file sildc/silcd.c.
64 * Put back the servers public key filename format, it is better
65 than the new one. For now, the client keys are saved with the
66 new filename format. The affected file silc/client_ops.c.
68 * Implemented the Cipher API for the rest of the ciphers that
69 did not implement it or implemented it the wrong way.
71 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
73 * Register default ciphers and stuff when using the -S option
74 in the client. Affected file silc/silc.c. Same also when
75 creating new key pair with -C option.
77 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
79 * Fixed the silc_verify_public_key client operation function to
80 save the public keys differently. The fingerprint is now
81 used as filename and not the hostname. This way also the
82 client keys are saved uniquely and not with hostnames. The
83 affected file is silc/client_ops.c.
85 * Trimmed the silc_hash_fingerprint function to remove extra
86 whitespaces from the end of the fingerprint. The affected
87 file is lib/silccrypt/silchash.c.
91 * Added silc_cipher_register_default function to register all
92 default ciphers. It can be used when configuration files
93 does not exist and the application does not want any specific
94 ciphers in any specific order.
96 The SilcDList is now used as silc_cipher_list dynamically
97 allocated cipher list. Removed the static list all together
98 and now all ciphers must be allocated to the dynamic list.
99 The silc_cipher_alloc routine was changed to check only the
102 All silc_cipher_* routines that used to return int returns
105 The affected files lib/silccrypt/silccrypt.[ch].
107 * The same thing was done to silc_hash_* as for silc_cipher_*
108 routines. Affected files lib/silccrypt/silchash.[ch].
110 * The same thing was done to silc_pkcs_* as for silc_cipher_*
111 routines. Affected files lib/silccrypt/silcpkcs.[ch].
112 Added also silc_pkcs_[un]register[_default] functions.
113 Removed the data_context from the PKCS API.
115 * Added silc_hmac_register_default function to register default
116 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
117 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
118 to unregister all hmacs at once.
120 * Register the default ciphers, hash functions, PKCSs and HMACs
121 if client's configuration file does not exist. The affected
124 * The client did not load the hash functions from the SIM
125 modules at all. Added support for this. Affected file is
128 * When decoding public key with silc_pkcs_public_key_decode, check
129 the supported algorithm only if PKCS are registered. Affected
130 file lib/silccrypt/silcpkcs.c. The same was done with the
131 silc_pkcs_private_key_decode.
133 * Fixed the SILC List routines to keep the list always in order.
134 It used to change the list's order when traversing the list but
135 not it preserves the order. Affected file lib/trq/silclist.h.
137 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
139 * Added the client library to use the SilcSocketConnection's
140 reference counter (by silc_socket_dup) to prevent the bug that
141 the socket object may be freed underneath async operation.
143 * The name resolv library checking fixes in the configure.in.pre.
146 * Created new version of the protocol drafts for future
147 development. The -03 drafts are the ones that will be changed
148 in the trunk now and the -02 will remain as they are.
150 * Send list of CUMODE notifys to the router when announcing
151 the channel users to the router. Affected file silcd/server.c.
152 If the router receiving channel founder CUMODE for a channel
153 that already has channel founder it will send CUMODE notify
154 to the sender to remove the channel founder rights from the
155 announced client. Affected file silcd/packet_receive.c.
157 * The CUMODE notify may now use Server ID as well as the entity
158 who changes the mode. Updated protocool specs.
160 * Updated INSTALL and README files.
162 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
164 * New web pages in the http://silc.pspt.fi. The pages was
169 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
171 * Implemented the [DenyConnectin] config section in the server.
172 Added silc_server_config_denied_conn to check whether incoming
173 connection is denied. Affected file silcd/serverconfig.[ch].
175 * Do not check the ports when checking the incoming configuration
176 data if the port is 0, meaning any. Affected file is
177 silcd/serverconfig.c.
179 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
181 * Fixed buffer overflow in silc_string_compare in the file
182 lib/silcutil/silcutil.c.
184 * Fixed double free in silc_server_command_leave in the file
187 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
189 * Fixed the version checking in the server. Affected file is
192 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
194 * Fixed the configuration data fetching when accepting new
195 connections in the server. Affected file silcd/server.c.
197 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
199 * Added `sender_entry' argument to the function
200 silc_server_packet_relay_to_channel so that we can check
201 whether some destination actually belongs to the same route
202 the sender belongs (ie, we must not resend the packet to the
203 sender). Affected file silcd/packet_send.[ch].
205 * Added `servername' field to the SilcClientEntry in the server
206 to hold the name of the server where client is from. Affected
207 file is silcd/idlist.h.
209 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
211 * Moved the channel message encrypting in the router betwen
212 router connections from silc_server_channel_message to the
213 silc_server_packet_relay_to_channel since we want to check
214 whether we have anybody channel before encrypting anything.
215 Affected files silcd/packet_[receive/send].c.
217 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
219 * Fixed the [AdminConnection] server config section to support
220 multiple entries. Affected file silcd/serverconfig.c.
222 * Added support into the server to check the validity of the
223 incoming connection before executing any KE or authentication
226 * The connection configuration is now saved to the KE and
227 connection auth protocol contexts and not fetched anymore in
228 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
230 * The local hosts listenning address and port is also resolved
231 now when starting the server. We want to have the socket object
232 to include the real address and port for the listener. Added
233 new function silc_net_check_local_by_sock into the files
234 lib/silcutil/silcnet.[ch].
236 * Fixed a broadcast bug in server -> do not broadcast if we
239 * Fixed a routing bug. Do not route broadcast packets ever.
240 Broadcast packets must be processed always and not routed since
241 they may be destined to some other host than yourself and thus
242 would get routed without no good reason. Affected file is
245 * Added function silc_server_config_is_primary_route to check
246 whether primary router connection has been configured (a router
247 configuration that we are initiating). If there is not, we
248 will assume that there is only two routers in the SILC network
249 and we will use the incoming router connection as our primary
250 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
252 * Changed the order of the broadcasting. Broadcast _after_ the
253 packet has been processed not before. Affected file is
256 * Fixed a [ClientConnection] parsing bug. The port was never
257 parsed correctly thus resulting to port 0. Affected file
258 silcd/serverconfig.c.
260 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
261 argument and did not set the broadcast packet flag. Affected
262 file silcd/packet_send.c. Fixed same bug in the function
263 silc_server_send_notify as well.
265 * If we receive NEW_ID packet for our own ID in the server, ignore
268 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
272 * Removed the nickname from the Private Message Payload.
273 Updated the code and the protocol specs.
275 * Updated protocol specs for submitting to the IETF.
277 * Tweaked the Random Number Generator a bit. Affected file
278 lib/silccrypt/silcrng.c. Exported a new function
279 silc_rng_[global]_add_noise which can be used to add more
282 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
284 * Do not parse packets with different timeout when protocol
285 is active -> may cause problem with rekey. Affected file
288 * When server receives signoff notify it must not create
289 new channel key if the client is on any channels since the
290 sender of the signoff notify will create it.
292 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
294 * Added printing of error messages during SKE protocol from the
295 failure packet sent by server during SKE. Affected file
298 * Removed the client's failure_callback handling with timeout
299 and handle it immediately when received.
301 * The SKE library returned wrong type in SUCCESS and FAILURE
302 packets. They must be 32 bit MSB not 16 bit MSB.
304 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
306 * Ok, rewrote the logic of the re-key and now it seems to work.
307 I tested it on high traffic with frequent re-keys without
308 problems. Added hmac_receive (and renamed hmac to hmac_send)
309 in SilcClientConnection in lib/silcclient/client.h and
310 in SilcIDListData in silcd/idlist.h. Also, removed the
311 SilcPacketParserContext's cipher and hmac fields as they are
312 not needed anymore and actually caused some problems when
313 the ciphers and hmac's changed underneath the packet parser.
315 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
317 * If re-key protocol is active then process the incoming packets
318 synchronously since we must assure that icoming packets encrypted
319 with the old key is processed before the new keys is set to
320 use. This is true other packets than for REKEY packets.
321 Affected file silcd/server.c. The same was done to client library
322 as well, affected file lib/silcclient/client.c.
324 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Fixed bug in client and server to accept the force send if
327 the packet is send from silc_[server/client]_packet_process
328 function. Otherwise the packets are never delivered, oops.
330 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
332 * Disable force sending of packets when REKEY protocol is active.
333 We must assure that no packet is sent directly when rekey is
334 performed. All packets must be sent through packet queue.
335 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
336 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
337 function is silc_[server/client]_packet_send_real to check
340 * Replaced the SIM paths from example config files to
341 /usr/local/modules. Also, make install creates now
342 /usr/local/silc/logs directory to hold all the SILC server
345 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
347 * Made the configure.in.pre work on Solaris. Patch by salo.
349 * Made all ciphers compatible with non-x86 machines. Defined
350 CBC mode macros into lib/silccrypt/ciphers_def.h.
352 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
354 * Fixed the make install.
356 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
358 * When MAC computation fails the silc_packet_decrypt returned 0
359 even though it was supposed to return -1. Fixed this. The
360 affected file is lib/silccore/silcpacket.c.
362 * Do not replace the config files in /etc/silc (in make install)
363 if they already exist. Affected file ./Makefile.am.
365 * Do not send re-key packets immediately but through packet queue.
366 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
368 * Changed silc_net_check_host_by_sock to return FALSE if the
369 IP/DNS could not be resolved. Though, it returns the IP address
370 now even if it could not resolve it (but returns also FALSE).
371 Affected file lib/silcutil/silcnet.[ch].
373 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
375 * Added silc_pkcs_decode_identifier to decode the public key's
376 identifier. Affected file lib/silccrypt/silpkcs.[ch].
377 Added also silc_pkcs_free_identifier. Added also new context
378 SilcPublicKeyIdentifier.
380 * Added -S option to the silc client. It is used to dump the
381 contents of the specified public key file.
383 * Changed the PKCS api to return the public key length when
384 setting the public key.
386 * Fixed a fatal bug in the public and private key file loading.
387 Affected file lib/silccrypt/silcpkcs.c.
389 * Execute the packet parsing for client with zero (0) timeout
390 if the protocol is active. Affected file silcd/server.c.
392 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
394 * Made the key generation options to the silcd program. Added
395 -C option, equivalent to client's option.
397 * Added new [ServerKeys] config section to the server. It
398 configures the server's public and private key.
400 * Defined generic Public Key Payload into the protocol
401 specification to send specific type of public keys and
404 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
405 public key or certificate.
407 * Implemented the GETKEY command to the server and to the
408 client library and on user interface.
410 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
412 * Made preliminary `make install' work.
414 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
416 * Added SilcServerRekey context into silcd/idlist.h.
418 * Added the PFS support as defined in the specification to the
419 SKE protocol. Affected files lib/silcske/*.c.
421 * Added `ske_group' field to the SilcServerRekey context to hold
422 the number of the SKE group that is used with PFS in re-key.
423 Affected file silcd/idlist.h.
425 * Added PFS re-key support to the server. Affected file is
428 * Added silc_protocol_cancel to cancel execution of the next
429 state of the protocol. Affected file is
430 lib/silccore/silcprotocol.[ch].
432 * Added the re-key support with and without PFS to the client
433 library. Re-key is performed once in an hour, by default.
435 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
436 Added silc_client_rekey_callback and silc_client_rekey_final.
437 Affected files are lib/silcclient/protocol.[ch] and
438 lib/silcclient/client.[ch].
440 * Removed the `hmac_key' and `hmac_key_len' fields from the
441 SilcClientConnection structure; not needed. Affected file is
442 lib/silcclient/client.h.
446 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
448 * Do not ask whether user wants to use the negotiated private key
449 for private messages, just use it. Affected file is
450 silc/local_command.c.
452 * Added `send_enc_key' and `enc_key_len' fields to the
453 SilcIDListData structure since they are needed in the re-key
454 phase. Affected file is silcd/idlist.[ch].
456 * Implemented the simple re-key protocol into the server.
457 Affected files silcd/server.c and silcd/protocol.[ch]. The
458 re-key will be performed once in an hour, by default.
460 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
461 Added silc_server_rekey, silc_server_rekey_callback and
462 silc_server_rekey_final.
464 * Removed Tunneled flag from the protocol. Updated the code
465 and the specifications.
467 * Adde `pfs' field to the SilcIDListData to indicate whether
468 the PFS is to be performed in the re-key. Affected file is
471 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
473 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
474 int64 of at least the xintXX size. If void * is less that 4
475 bytes uint32 * will be used. Defined bool as boolean.
477 * Changed _ALL_ unsigned long and unsigned int to uint32,
478 unsgined short to uint16 in the source tree.
480 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
481 not handle clients that has entry->data.registered == FALSE.
482 They are not in the network anymore. Affected file is
485 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
487 * Implemented the sending of the SERVER_SIGNOFF notify in the
488 server. Affected file is silcd/server.c.
490 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
491 Added also silc_notify_payload_encode_args into the
492 lib/silccore/silcnotify.[ch].
494 * Implemented ther SERVER_SIGNOFF notify handling in the server.
495 Affected file silcd/packet_receive.c.
497 * Implemented the SERVER_SIGNOFF notify handling in the client
498 library. Affected file lib/silcclient/client_notify.c. Also,
499 implemnted the printing of the SERVER_SIGNOFF info to the
500 application. Affected file silc/client_ops.c.
502 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
503 if the deleting was successful. Affected file silcd/idlist.[ch].
505 * Added support for public key authentication in the connection
506 authentication protocol in the client library. Affected file
507 lib/silcclient/protocol.c.
509 * Changed the server's silc_idlist_get_clients_by_* interface
510 to support already allocated array so that new entries may be
511 added to pre-allocated array. Affected file silcd/idlist.[ch].
512 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
515 * All command reply functions in the server now calls the
516 pending command callback even if error occured. This way the
517 error will be delivered to the client as well. Affected files
518 silcd/command.c and silcd/command_reply.c.
520 * Fixed INFO command to return local server's info if no server
521 was provided. Affected file lib/silcclient/command.c.
523 * Removed RESTART command for good. Updated the code and the
526 * Rewrote parts of the task system. It is a bit simpler now.
527 Removed unsued task priorities. The affected files are
528 lib/silcutil/silctask.[ch].
530 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
532 * Moved the USERS printing from the library to the application.
533 Affected files lib/silcclient/command.c and silc/client_ops.c.
535 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
539 * Added channel key re-key support. The re-key is perfomed
540 only by the router and is done once in an hour. Added `rekey'
541 field to the SilcChannelEntry in the server. Affected files
542 silcd/server.c and silcd/idlist.h.
544 * Added silc_task_unregister_by_context into the file
545 lib/silcutil/silctask.[ch].
547 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
549 * Added SILC_UMODE_GONE mode to indicate when the client is not
550 present in the SILC network. Added also support to the local
551 command AWAY that will set this mode. Added support of showing
552 "xxx is gone" in WHOIS command. The USERS command shows the
555 * Fixed setting server and router operator privileges in the
556 server's UMODE command. Affected file silcd/command.c.
558 * Merged the SKE KE1 and KE2 payloads into one payload. The
559 new KE payload is equivalent to the old KE2 payload.
561 Cleaned up the SKE Start Payload parsing. It now uses the
562 simple buffer unformatting to do the parsing. A lot faster
565 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
566 to the SKE that is used to indicate whether both of the SKE
567 parties should perform authentication. By default only the
568 responder performs authentication. By setting this flag also
569 the initiator must do authentication. By default it is unset
570 since in normal SKE case, client to server connection, only
571 the responder should do authentication. When doing SKE between
572 two clients both should perform authentication. Updated the
573 code and the protocol specs.
575 * A little fix to IDENTIFY command in the server. Search the
576 client first by hash not nickname. Affected file is
579 * Fixed the silc_client_close_connection to support closing
580 the client to client connections wihtout deleting too much
581 data. Affected file lib/silcclient/client.c.
583 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
584 are received if protocol used to be active but is not anymore
585 the application would crash due to NULL pointer dereference.
586 Affected files silcd/server.c and lib/silcclient/client.c.
588 * Added `hash' field to the SilcClientConnection to include
589 the hash function negotiated in the SKE protocol.
591 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
592 to set the channel founder authentication data. A client can
593 claim the founder rights later by providing the authentication
594 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
595 This way the channel founder can regain the channel founder
596 privileges even it is left the channel. This works only on
597 local server and the client must be connected to the same
598 server to be able to regain the founder rights. Updated the
599 protocol specs accordingly.
601 Added support to the CMODE command in the client to set the
602 founder auth data. Read the README to see how to set it.
604 Added support to the CUMODE command to claim the founder
605 rights. Read the README to see how to do it.
607 Added support for the founder authentication to the Channel
608 Entry in the server. Affected file silcd/idlist.h.
610 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
611 server's CMODE command. Affected file silcd/command.c.
613 * Added the following new functions into lib/silccore/silcauth.[ch]:
614 silc_auth_get_method and silc_auth_get_data.
616 * The server now saves the remote hosts public key to the
617 SilcIDListData pointer. Affected file silcd/protocol.c.
619 * The normal server now does not remove the channel entry from
620 the cache if the founder authentication data is set. It used
621 to remove it if the founder was the last one on the channel on
622 the server and left the channel. The auth data is saved and
623 if the channel is re-joined later the old entry is used with
624 the old auth data. Affected files silcd/command_reply.c and
627 * Removed the `pkcs' field from the SilcIDListData structure
628 in the server; it is not used. Affected file silcd/idlist.h.
630 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
632 * Fixed packet processing on slow links. Partial packets were
633 never re-processed because the incoming data buffer was cleared
634 by the application. Application must not directly clear the
635 sock->inbuf, the packet processing routines handle it. Fixed
636 this in client library and in server.
638 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
640 * Fixed the WHOIS and IDENTIFY send reply function to really
641 check whether to send list or just one entry. Affected file
644 * Cleaned up the LEAVE command's channel key distribution. The
645 affected file silcd/command.c.
647 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
648 can enforce the channel mode as well. In that case the ID
649 includes the ID of the server. The code now enforces the
650 mode change if the router have different mode than the server.
652 * The notify client operation with CMODE_CHANGE notify can now
653 return NULL client_entry pointer if the CMODE was not changed
654 by client. Application must check for this.
656 * Added <Server ID> argument to INFO command to support server
657 info fetching by Server ID.
659 * Added silc_server_announce_get_channel_users to get assembled
660 packets of channel users of the specified channel. Affected
661 file silcd/server.[ch].
663 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
664 was freed underneath the ID Cache.
666 * Re-announce clients when the server received CHANNEL_CHANGE
667 notify from the router. Affected file silcd/packet_send.c.
669 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
671 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
672 crashed since it did not handle the fact that there is no cipher
673 called "3" and didn't check the error condition. Now fixed.
675 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
676 flag. It can be used to send message requests.
678 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
680 * Implemented the RESTART command in the client.
682 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
683 notice type messages. Added notice printing to the user
686 * The channel keys are not re-generated if the channel's mode
687 is PRIVKEY, ie private key on the channel exists. Affected
688 files silcd/server.c and silcd/command.c.
690 * Fixed a little bug in channel message delivery when channel
691 private keys are set in the server. Affected file is
694 * Changed the setting on channel->on_channel = TRUE from the
695 silc_client_save_channel_key to the JOIN command reply. The
696 key payload is not received if the private channel key is set.
697 Affected file lib/silcclient/command_reply.c and the
698 lib/silcclient/client_channel.c.
700 * When the CMODE_CHANGE notify is sent and the channel private
701 key mode is removed the channel key must be re-generated in
702 other cells as well. Added this support for the router in the
703 silcd/packet_receive.c.
705 * Added new local command NOTICE to send notice message on
706 channel. Affected file silc/local_command.[ch].
708 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
710 * Added new local command ME to the client. It is used to send
711 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
712 some action. Affected file silc/local_command.[ch].
714 * Changed channel_message and private_message client operations
715 to deliver the message flags to the application. Added also
716 the `flags' arguments to the silc_client_send_channel_message
717 and silc_client_send_private_message functions. Affected file
720 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Redefined the Private Message Payload to support private message
723 keys and to support the new private message flags. Updated
724 the protocol specs. Flags makes it possible to have for example
727 * Added new type SilcPrivateMessagePayload and defined an API
728 for it in the lib/silcclient/silcprivate.[ch].
730 * Tested private message private keys successfully. Tested the
731 private message key set, unset and list commands with the new
734 * Redefined the Channel Message Payload to include the channel
735 message flags (equal with private message flags) to support
736 for example CTCP style messages.
738 * Defined some of the message (for channel and private message)
739 flags. Updated the protocol specs and added the flags to the
740 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
742 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
744 * Added SilcKeyAgreementStatus type to the key agreement routines
745 to indicate the current status and error if one occured.
746 The status types are defined in the lib/silcclient/silcapi.h.
748 * Added new local command KEY that is used to set and unset private
749 keys for channels, set and unset private keys for private messages
750 with remote clients and to send key agreement requests and
751 negotiate the key agreement protocol with remote client. The
752 key agreement is supported only to negotiate private message keys,
753 it currently cannot be used to negotiate private keys for channels,
754 as it is not convenient for that purpose.
756 * Fixed a minor pending callback setting bug in the function
757 silc_client_get_client_by_id_resolve, now the function works.
758 Affected file lib/silcclient/idlist.c.
760 * Added function silc_net_get_local_port to get local bound
761 port by socket. Added to lib/silcutil/silcnet.[ch].
763 * Added `sockets' and `sockets_count' fields to the SilcClient
764 object. They hold the sockets of the listenning sockets in
765 the client. Listenning sockets may be for example the key
766 agreement server. Affected file lib/silcclient/client.[ch].
767 Added functions the silc_client_add_socket and the
768 silc_client_del_socket. They are exported to the application
771 * Added ~./silc/clientkeys to support other client's public keys.
773 * Renamed verify_server_key client operation to verify_public_key
774 and added one argument to indicate the type of the connection
775 (server, client etc.).
777 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
779 * Added silc_server_connection_auth_request to handle the
780 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
781 silcd/packet_receive.[ch].
783 * Added silc_server_send_connection_auth_request into the
784 silcd/packet_send.c to send the connection auth request packet.
786 * Cleaned up the silcd/protocol.c a bit and fixed some memory
789 * Fixed the public key authentication in responder side in the
790 server. The `auth_data' pointer includes the SilcPublicKey
791 not the path to the public key. Affected file silcd/protocol.c.
793 * Implemented the public key authentication in the initiator side
794 in the server. Affected file silcd/protocol.c.
796 * Removed the [RedirectClient] config section from the server
797 configuration. Is not needed and I don't want to implement it.
799 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
801 * Cleaned up the CMODE command in the server. It now works
802 correctly and supports all the modes defined in the protocol.
803 Affected file is silcd/command.c.
805 * Added `hmac_name' field to the SilcChannelEntry in the server
806 to hold the default HMAC of the channel. It can be set when
807 creating the channel (with JOIN command). Affected files
810 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
811 type to indicate the change of the current cipher and hmac
812 on the channel. Client can safely ignore the <cipher> argument
813 (if it chooses to do so) since the CHANNEL_KEY packet will
814 force the channel key change anyway. The <hmac> argument is
815 important since the client is responsible of setting the new
816 HMAC and the hmac key into use.
818 * Fixed the CMODE command in the client library as well.
820 * Tested CMODE command in router environment successfully.
822 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
824 * Show the version of the remote client (or server) when connecting
825 to the server. It is logged to the log file. Affected file
828 * Fixed the KILLED notify handling in the client library. The
829 client must be removed from all channels when receiving the
832 Also, do not remove the client entry when giving the KILL
833 command but when the KILLED notify is received.
835 * Removed silc_idlist_find_client_by_nickname from the server.
836 Not needed anymore. Affected files silcd/idlist.[ch].
838 * Implemented the CHANNEL_CHANGE notify type handling to the
839 server. Affected file silcd/server.c.
843 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
845 * Added silc_server_send_notify_invite to send the INVITE
846 notify between routers.
848 * Implemented the INVITE command correctly to the server.
850 * Implemented the INVITE notify type handling in the server.
852 * Implemented the INVITE command to the client library and on the
855 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
857 * Added function silc_server_get_client_resolve to find the
858 client entry by ID from all ID lists and then resolve it
859 (using WHOIS) if it cannot be found. Affected file is
862 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
864 * Implemented the BAN command to the client library.
866 * The JOIN command in the server now checks the invite list
869 * Changed the silc_command_reply_payload_encode_va and the
870 silc_command_payload_encode_va to support that if argument is
871 NULL it ignores and checks the next argument. Affected file
872 lib/silccore/silccommand.c.
874 * Added silc_server_send_notify_ban to send the BAN notify
875 type between routers.
877 * Chaned the silc_notify_payload_encode to support that if
878 argument is NULL it ignores and checks the next argument.
879 Affected file lib/silccore/silcnotify.c.
881 * Tested ban lists in router environment successfully.
883 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
885 * Implemented BAN command to the server, in silcd/command.[ch].
887 * Removed the BAN and INVITE_LIST modes from the CMODE command
890 * Added function silc_string_match to regex match two strings.
891 Affected files lib/silcutil/silcutil.[ch].
893 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
895 * Redefined parts of the SilcChannelEntry in the server to support
896 the new ban and invite lists.
898 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
900 * Redefined the INVITE command. The same command can be used to
901 invite individuals to the channel but also to manage the invite
902 list of the channel (to add to and remove from the invite list).
903 Updated the protocol specs.
905 * Added new command SILC_COMMAND_BAN that can be used to manage
906 the ban list of the channel. Updated the protocol specs.
908 * Removed the channel modes: the SILC_CMODE_BAN and the
909 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
910 in the CMODE command. The equivalent features are now available
911 using INVITE and BAN commands. Updated the protocol specs.
913 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
914 in the network about change in the current ban list. The notify
915 type is not used by the client.
917 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
918 support the invite lists.
920 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
922 * Added new function silc_string_regexify that converts string
923 including wildcard characters into regex string that can
924 be used by the GNU regex library. Added into the file
925 lib/silcutil/silcutil.[ch].
927 Added silc_string_regex_combine to combine to regex strings
928 into one so that they can be used as one regex string by
929 the GNU regex library. Added into the file
930 lib/silcutil/silcutil.[ch].
932 Added silc_string_regex_match to match two strings. It returns
933 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
935 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
937 * Imported GNU regex to the soruce tree into lib/contrib.
938 Fixed some compiler warning from the regex.c.
940 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
942 * Fixed MOTD command in the server to work in router environment.
944 * Fixed the MOTD command in the client library to support
945 the server argument in the command.
947 * Added `nickname_len' argument to the silc_idlist_add_client
948 in the server, as the `nickname' argument may be binary data
951 * Added silc_idlist_get_channels to return all channels from
954 * Implemented LIST command to the server. Affected file is
957 * Implemented the LIST command to the client library and on the
960 * Added [<user count>] argument to the LIST command reply.
961 With private channels the user count is not shown.
963 * Updated TODO and README.
965 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
967 * The client entry's data.registered must be TRUE even with
968 global client entry on global client list. The data.registered
969 is used to check whether the client is anymore in the network,
970 for example with WHOWAS command so it must be valid.
972 * Fixed the WHOWAS command in the server. It now actually works
973 in router environment. Added function into silcd/command_reply.c
974 silc_server_command_reply_whowas_save.
976 * Added silc_idlist_purge function to the silcd/idlist.c
977 to periodically purge the ID Cache.
979 * Fixed INFO command in the server. It works now in router
980 environment. Added <server name> argument to the INFO command
981 reply. Updated the protocol specs.
983 * Fixed minor bug in silc_idcache_purge to not purge if the
984 expire value is zero.
986 * Fixed various bugs in WHOIS and IDENTIFY command handling as
987 they were buggy because of the WHOWAS information.
989 * Fixed local command MSG to handle the async resolving of
990 the remote client properly. It used to fail the first MSG.
991 Affected file silc/local_command.c.
993 * Added `data_len' field to SilcIDCache context.
995 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
997 * Update TODO. Todo in commands in the server.
999 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1001 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1002 used by routers as broadcast packet to inform other routers
1003 about the changed user mode.
1005 Implemented the notify handling in the server. Affected file is
1006 silcd/packet_receive.c. Added the function
1007 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1009 * Added new generic Channel Payload and deprecated the New Channel
1010 Payload. The New Channel Payload is now the generic Channel
1013 * Added new argument `mode' to the silc_server_send_new_channel
1014 as it is required in the Channel Payload now.
1016 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1017 and created a new and real SilChannelPayload to represent the
1018 new generic Channel Payload. Implemented the encode/decode
1019 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1021 * Added silc_server_get_client_channel_list to return the list
1022 of channels the client has joined for WHOIS command reply.
1023 Affected file silcd/server.[ch].
1025 * Implemented the channel list sending in the WHOIS command reply
1026 in server and in the client.
1028 Implemented the channel list displaying on the user interface
1029 as well. Affected file silc/client_ops.c.
1031 * Added silc_channel_payload_parse_list to parse list of Channel
1032 Payloads. It returns SilcDList list of SilcChannelPayloads.
1033 Client for example can use this function to parse the list of
1034 channels it receives in the WHOIS command reply. The caller
1035 must free the list by calling silc_channel_payload_list_free.
1036 Affected files lib/silccore/silcchannel.[ch].
1038 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1040 * Added one new argument <user mode> to the WHOIS command reply
1041 to return the mode of the user in SILC. Updated the protocol
1044 Implemented it to the server and client.
1046 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1048 * Fixed the mode printing on the user interface on joining.
1049 Affected file silc/client_ops.c.
1051 * Implemented the UMODE command and user modes in general to the
1052 client library and to the user interface.
1054 * Implemented the UMODE command to the server.
1056 * The server now sends UNKNOWN_COMMAND error status if client sends
1057 unknown command. Affected file silcd/command.c.
1059 * All server commands now handle the command identifier the right
1060 way when sending the command reply to the client. The client can
1061 use to identify the command replies with the identifier.
1063 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1065 * Added silc_server_get_client_route to resolve the route to
1066 the client indicated by the client ID. Affected file is
1069 * Added silc_server_relay_packet as general function to relay
1070 packet to arbitrary destination. This deprecates functions
1071 like _send_private_message_key, _relay_notify etc. Affected
1072 file is silcd/packet_send.[ch].
1074 Removed silc_server_send_key_agreement,
1075 silc_server_send_private_message_key and
1076 silc_server_packet_relay_notify functions from the file
1077 silcd/packet_send.[ch].
1081 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1082 server. Affected file silcd/packet_receive.[ch].
1084 * Implemented the KILL command to the client. Implemented the
1085 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1086 Affected files lib/silcclient/command[_reply].c and
1087 lib/silcclient/client_notify.c. Implemented the KILL notify
1088 printing in the user inteface.
1090 * Fixed a lot silc_parse_nick memory leaks from the client
1091 library in the file lib/silcclient/command.c.
1093 * Changed the silc_server_send_notify_on_channels's `sender'
1094 argument from SilcSocketConnection to SilcClientEntry to
1095 check the sender as entry and not as connection object and not
1096 to send to the client provided as argument. The affected file
1097 is silcd/packet_send.[ch].
1099 * The notify packets that are destined directly to the client used
1100 to not to be processed by the server. Now changed that and the
1101 server processes all notify packets. After relaying the packet
1102 to the client the notify packet is processed in the server.
1104 * The silc_server_free_client_data now checks whether there is
1105 pending outgoing traffic for the client and purges the data to
1106 the network before removing the client entry.
1108 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1110 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1111 an client is killed from the SILC Network. Updated the protocol
1114 Added new function silc_server_send_notify_killed to the
1115 silcd/packet_send.[ch].
1117 * Added function silc_server_packet_relay_notify to relay notify
1118 packets that are destined directly to a client. In this case
1119 the server does not process the notify packets but merely relays
1120 it to the client. Affected file silcd/packet_send.[ch].
1122 Added also silc_server_packet_process_relay_notify to check
1123 whereto relay the notify. Affected file is
1124 silcd/packet_receive.[ch].
1126 * Implemented the KILL command to the server.
1130 * Added the backup schema desgined last fall to the protocol
1131 specs for everyone to see. The specification is in the
1132 *-spec-xx.txt draft and the packet type definitions for the
1133 backup routers is in *-pp-xx.txt draft. Thusly, added also
1134 new packet type SILC_PACKET_CELL_ROUTERS.
1136 * A big security problem in the implementation discovered. The
1137 signoff of an client did not cause new channel key generation
1138 which it of course should've done. The channel keys must be
1139 always re-generated when client leaves (or signoffs) the channel.
1140 The silc_server_remove_from_channels funtion now handles
1141 the channel key re-generation.
1143 * Added `sender' argument to the silc_server_send_notify_on_channels
1144 to not to send the client provided as argument. Affected file
1145 silcd/packet_send.[ch].
1147 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1149 * Implemented OPER and SILCOPER commands into the server and
1152 * Added silc_auth_verify and silc_auth_verify_data to verify
1153 the authentication directly from the authentication payload.
1154 It supports verifying both passphrase and public key based
1155 authentication. Affected file lib/silccore/silcauth.[ch].
1157 * Added `hash' field to the SilcIDListData structure. It is the
1158 hash negotiated in the SKE protocol. Affected file is
1161 * Slight redesigning of the SilcAuthPayload handling routines.
1162 Do not send SilcPKCS but SilcPublicKey as argument.
1164 * Implemented the public key authentication support to the
1165 serverconfig. The public key is loaded from the provided path
1166 and saved as authentication data to void * pointer. Thus,
1167 changed the unsigned char *auth_data to void *auth_data;
1169 * Fixed SHUTDOWN command to send the reply before the server
1170 is shutdown. :) Affected file silcd/command.c.
1172 * Fixed fatal bug in CONNECT command. The hostname was invalid
1173 memory and server crashed. Affected file silcd/command.c.
1175 * Fixed fatal bug in CLOSE command. The server_entry became
1176 invalid but was referenced later in the command. Affected file
1179 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1181 * Fixed fatal bug in failure packet handling. Server ignored
1182 the failure and thus crashed when it came.
1186 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1188 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1189 that the command may be executed only once in (about) 2 seconds.
1190 The old SILC_CF_LAG flag is same but allows command bursts up
1191 to five before limiting.
1193 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1194 server code. Various commands now includes the CF_LAG_STRICT
1195 flag to disallow any kind of miss-use of the command.
1197 * Fixed the silc_buffer_unformat to not to allocate any data
1198 if the length of the data is zero. It used to allocate the
1199 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1201 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1203 * Changed the format of AdminConnection configuration section
1204 in the server. Added username of the admin to the format.
1205 Affected files silcd/serverconfig.[ch].
1207 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1208 to return admin configuration data by host, username and/or
1211 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Implemented WHOWAS command to the server. Added the functions:
1215 silc_server_command_whowas_parse,
1216 silc_server_command_whowas_send_reply,
1217 silc_server_command_whowas_from_client and
1218 silc_server_command_whowas_from_server
1220 * Added <Client ID> argument to the WHOWAS command reply. Updated
1221 the protocol specs accordingly.
1223 * Implemented WHOWAS command and command_reply to the client
1226 Implemented the WHOWAS printing on the user interface.
1228 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1230 * Added new argument to the WHOWAS command reply, the real name.
1231 It is an optional argument. Updated the protocol specs.
1233 * Added SilcIDCacheDestructor callback that is registered when
1234 the SilcIDCache is allocated. The callback is called when
1235 an cache entry in the ID Cache expires, or is purged from the
1236 cache. Added into lib/silccore/idcache.[ch].
1238 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1239 to destruct the client entries when the cache entry expires.
1240 Other ID Cache's in server and in the client library ignores
1243 * If the ID Cache entry's `expire' field is zero then the entry
1244 never expires. Added boolean `expire' argument to the
1245 silc_idcache_add function in the lib/silccore/idcache.[ch].
1246 If it is TRUE the default expiry value is used.
1248 * Added silc_server_free_client_data_timeout that is registered
1249 when client disconnects. By default for 5 minutes we preserve
1250 the client entry for history - for WHOWAS command.
1252 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1254 * Added support to the server to enforce that commands are not
1255 executed more than once in 2 seconds. If server receives
1256 commands from client more frequently, timeout is registered
1257 to process the commands. Affected file silcd/command.c.
1258 Added new function silc_server_command_process_timeout.
1260 * Changed NICK_NOTIFY handling in client library to check that
1261 if the client's nickname was changed, so there is no need to
1262 resolve anything from the server.
1264 * Removed error printing from the WHOIS and IDENTIFY commands.
1265 If error occurs then it is ignored silently in the client library.
1266 The application, however, may map the received error to
1267 human readable error string. The application currently maps
1268 the NO_SUCH_NICKNAME error to string.
1270 * Made the command status message public to the application. Moved
1271 them from lib/silcclient/command_reply.c to
1272 lib/silcclient/command_reply.h. The application can map the
1273 received command status to the string with the
1274 silc_client_command_status_message function.
1276 * Added check to the server to check that client's ID is same
1277 as the Source ID in the packet the client sent. They must
1280 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1282 * Added dist-bzip hook to the Makefile.am to make bzip2
1283 compressed distributions.
1285 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1287 * Server now enforces the maximum length for the nickname and
1288 the channel as protocol specification dictates. 128 bytes for
1289 nickname and 256 bytes for channel name.
1291 * Moved the WHOIS printing to the application. The client libary
1292 does not print out the WHOIS information anymore, the application
1293 must do it. Renamed silc_client_command_reply_whois_print to
1294 the silc_client_command_reply_whois_save.
1296 The client's idle time is also sent to the application now, and
1297 the idle is shown on screen.
1299 * Added silc_client_command_reply_identify_save to save the
1300 received IDENTIFY entries.
1302 * Do not check for channel private keys in message sending and
1303 reception if the channel does not have the PRIVKEY mode set.
1304 Affected file lib/silclient/client_channel.c.
1306 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1308 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1309 just surfaced after chaning the JOIN procedure.
1311 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1313 * Added silc_client_get_clients_by_list to get client entries
1314 from Client ID list, that is returned for example by JOIN
1315 and USERS command replies. The application should use this
1316 function for example when JOIN command reply is received to
1317 resolve the clients already on the channel (library does not
1318 do that anymore as USERS command reply is not used in the JOIN
1319 procedure anymore). Affected files lib/silcclient/silcapi.h and
1320 lib/silcclient/idlist.c.
1322 * JOIN command reply and USERS command reply returns now SilcBuffer
1323 pointers instead of unsigned char pointers when returning
1324 the client list and mode list.
1326 * Added <Client ID> argument to the JOIN command reply, mainly
1327 for the server to identify for which client the command was
1328 originally sent. Updated protocol specs accordingly.
1330 * Added SilcDlist private_key pointer to the SilcChannelEntry
1331 in the client to support the channel private keys. Affected
1332 file is lib/silcclient/idlist.h.
1334 * Added SilcChannelPrivateKey argument to the function
1335 silc_client_send_channel_message so that application can choose
1336 to use specific private ke if it wants to. If it is not provided,
1337 the normal channel key is used, unless private keys are set.
1338 In this case the first (key that was added first) is used
1339 as the encryption key.
1341 * Implemented the support for channel private key handling.
1342 Implemented the following functions:
1344 silc_client_add_channel_private_key,
1345 silc_client_del_channel_private_keys,
1346 silc_client_del_channel_private_key,
1347 silc_client_list_channel_private_keys and
1348 silc_client_free_channel_private_keys
1350 Affected file lib/silcclient/client_channel.c.
1352 * Added the support for the private keys in the channel message
1353 sending and encryption and in the message reception and
1354 decryption. Affected funtions are
1355 silc_client_send_channel_message and silc_client_channel_message.
1357 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1359 * Added SKE's key verify callback to the client library's
1360 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1362 * Removed the statement that server (or router) must send USERS
1363 command reply when joining to the channel so that the client
1364 knows who are on the channel. Instead, the client list and
1365 client's mode list is now sent in the JOIN command reply to the
1366 client who joined channel. This is better solution.
1368 * Added function silc_server_get_users_on_channel and function
1369 silc_server_save_users_on_channel to the silcd/server.[ch].
1371 * Removed function silc_server_command_send_users from the
1374 * Do not show topic on the client library anymore. The topic is
1375 sent in the command reply notify to the application and the
1376 application must show the topic now.
1378 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1380 * Added client searching by nickname hash into the IDENTIFY and
1381 WHOIS commands in the server as they were clearly missing from
1382 them. Affected file is silcd/command.c.
1384 * Fixed a bug in private message receiving in the client library.
1385 The remote ID was freed and it wasn't supposed, now it is
1388 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1390 * Minor fix to the channel payload; allocate the data area, as it
1391 needs to be of specific length.
1393 * If the key agreement port is zero then the operating
1394 system will define the bound port. Affected files are
1395 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1397 * Added new function silc_channel_payload_decrypt into the file
1398 lib/silccore/silcchannel.[ch].
1400 * Moved the channel message etc, check from silc_packet_decrypt
1401 to applications. The library calls now a generic
1402 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1403 when the packet is either normal or special. This was done to
1404 allow more wide range of checking that was not allowed when
1405 the code was in library. Now applications can do virtually any
1406 checks to the packet and return to the library the decision how
1407 the packet should be processed. Affected files are
1408 lib/silccore/silcpacket.[ch].
1410 Added silc_server_packet_decrypt_check to the server and
1411 silc_client_packet_decrypt_check to the client library.
1413 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1414 to send with specified source and destination information.
1416 * Channel message delivery between routers was broken after the
1417 channel key distribution was fixed earlier. The channel key
1418 was used be to distributed to other routers as well which is not
1419 allowed by the protocol. Now this is fixed and channel keys
1420 really are cell specific and the channel message delivery between
1421 routers comply with the protocol specification.
1423 * Fixed various commands in server to check also the global list
1424 for the channel entry and not just the local list. The affected
1425 file silcd/command.c.
1427 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1429 * Added assert()s to buffer formatting and unformatting routines
1430 to assert (if --enable-debug) when error occurs. Affected
1431 file: lib/silcutil/silcbuffmt.c.
1433 * Changed to auto-reconnect to check whether the remote host is
1434 router and register the re-connect timeout if it is. It used
1435 to check that whether we are normal server, but router must do
1436 auto-reconnect with another router as well. Affected file
1439 * Removed the [<key len>] option from CMODE command as the cipher
1440 name decides the key length, nowadays. See the defined ciphers
1441 from the protocol specification.
1443 * Added [<hmac>] option to the CMODE command to define the HMAC
1444 for the channel. Added SILC_CMODE_HMAC channel mode.
1446 * Added [<hmac>] option for the JOIN command so that user can
1447 select which HMAC is used to compute the MACs of the channel
1450 * Added Hmac field to the Channel Message Payload. The integrity
1451 of plaintext channel messages are now protected by computing
1452 MAC of the message and attaching the MAC to the payload. The
1453 MAC is encrypted. Now, it is clear that this causes some
1454 overhead to the size of the packet but rationale for this is that
1455 now the receiver can verify whether the channel message decrypted
1456 correctly and also when private keys are set for the channel the
1457 receiver can decrypt the packet with several keys and check from
1458 the MAC which key decrypted the message correctly.
1460 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1461 lib/silccrypt/silccipher.[ch].
1463 * Added silc_hash_len to return the digest length into the
1464 lib/silcrypt/silchash.[ch].
1466 * Rewrote parts of Silc Channel Payload interface in the
1467 lib/silccore/silcchannel.[ch]. The encode function now also
1468 encrypts the packet and parse function decrypts it.
1470 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1472 * Fixed a minor formatting bug in the SKE's key material processing.
1473 It actually might have processed the keys wrong way resulting
1476 * Redefined the mandatory HMAC algorithms and added new algorithms.
1477 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1478 and hmac-md5 truncated to 96 bits. The mandatory is now
1479 hmac-sha1-96. Rest are optional (including the one that used
1480 to be mandatory). Rationale for this is that the truncated HMAC
1481 length is sufficient from security point of view and can actually
1482 make the attack against the HMAC harder. Also, the truncated
1483 HMAC causes less overhead to the packets. See the RFC2104 for
1486 * Added new [hmac] configuration section. The SKE used to use
1487 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1488 is of course wrong. The official names that must be proposed in
1489 the SKE are the ones defined in the protocol specification
1490 (hmac-sha1-96 for example). The user can configure any hmac
1491 using any hash function configured in the [hash] section. At
1492 least, the mandatory must be configured.
1494 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1496 * Added HMAC list to the SKE proposal list. It has now both
1497 hash algorithm list and HMAC list. This makes the protocol
1498 incompatible with previous versions. The SKE now seems to work
1499 the way it is supposed to work, for the first time actually.
1501 * Defined plain Hash algorithms to the protocol specification.
1504 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1506 * Implemented support for key agreement packets into the server.
1507 Added functions silc_server_key_agreement and
1508 silc_server_send_key_agreement. Other than these functions,
1509 server has nothing to do with this packet.
1511 * Added support for private message key packets into the server.
1512 Added functions silc_server_private_message_key and
1513 silc_server_send_private_message_key.
1517 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1518 called in the protocol's final callback instead in the END
1519 protocol state. This makes a little more sense and in the same
1520 time in client we can use the same protocol routines for normal
1521 key exchange and to key agreement packet handling as well.
1523 * Added to both client's and server's KE protocol context the
1524 SilcSKEKeyMaterial pointer to save the key material. We will
1525 bring the key material to the protocol's final callback by doing
1526 this. The final callback must free the key material.
1528 * Added SKE's packet_send callback into client's KE protocol
1529 context so that the caller can choose what packet sending function
1530 is used. This way we can use different packet sending when
1531 doing normal SKE when doing key agreement packet handling (in
1532 the key agreement packet handling we do not want to encrypt
1535 * Implemented the responder side of the key agreement routines
1536 in the client. The client can now bind to specified port and
1537 accept incoming key negotiation. The key material is passed
1538 to the application after the protocol is over.
1540 * Implemented the processing of incoming Key Agreement packet
1541 in the client. Added function silc_client_key_agreement to
1544 * Implemented the intiator side of the key agreement routines
1545 in the client. The client can now initiate key agreement with
1546 another remote client. The key material is passed to the
1547 application after the protocol is over.
1549 * Created client_keyagr.c to include all the key agreement
1552 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1553 SILC_TASK_CALLBACK except that it is not static.
1555 * Created client_notify.c and moved the Notify packet handling
1556 from the client.[ch] into that file.
1558 * Created client_prvmsg.c and moved all private message and
1559 private message key routines from the client.[ch] into that file.
1561 * Create client_channel.c and moved all channel message and
1562 channel private key routines from the client.[ch] into that file.
1564 * Changed silc_client_get_client_by_id_resolve to resolve with
1565 WHOIS command instead of IDENTIFY command, in the file
1566 lib/silclient/idlist.c.
1568 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1570 * Implemented the SKE's responder side to the Client library.
1572 * When FAILURE is received to the protocol do not trust it
1573 blindly. Register a timeout to wait whether the remote closes
1574 the connection as it should do it, only after that process the
1575 actual failure. This was changed to both client and server.
1577 * Added client_internal.h to include some of the structures
1578 there instead of client.h in lib/silcclient/.
1580 * Added function silc_task_unregister_by_callback to unregister
1581 timeouts by the callback function.
1583 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1585 * Some "Incomplete WHOIS info" errors has been appearing on the
1586 log files. Took away the entry->userinfo check from WHOIS
1587 reply sending. The entry->userinfo is now " " if client did not
1588 provide one. I thought this was fixed earlier but something
1589 is wrong still. Let's see if the error still appears.
1591 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1593 * Fixed a minor bug in the login when the channel key is
1594 re-generated in the server. It used to generate the key in
1595 wrong order and thus caused problems in the channel traffic.
1597 * Fixed a minor bug in channel key distsribution after
1598 KICK command. The key was not sent to the router even though
1601 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1603 * Added silc_ske_process_key_material_data as generic routine
1604 to process any key material as the SILC protocol dictates. The
1605 function is used by the actual SKE library but can be used by
1606 applications as well. This relates to the private message keys
1607 and the channel private keys since they must be processed the
1608 same way the normal SILC session keys. The protocol dictates
1609 this. Affected files: lib/silcske/silcske.[ch].
1611 Added also silc_ske_free_key_material to free the
1612 SilcSKEKeyMaterial structure.
1614 * Defined silc_cipher_set_key function to set the key for
1615 cipher without using the object's method function. The affected
1616 files: lib/silccrypt/silccipher.[ch].
1618 * Implemented silc silc_client_add_private_message_key,
1619 silc_client_add_private_message_key_ske,
1620 silc_client_del_private_message_key,
1621 silc_client_list_private_message_keys and
1622 silc_client_free_private_message_keys functions in the
1625 Added functions silc_client_send_private_message_key to send
1626 the Private Message Key payload and silc_client_private_message_key
1627 to handle incoming Private Message Key payload.
1629 * Added Cipher field to the Private Message Key payload to set
1630 the cipher to be used. If ignored, the default cipher defined
1631 in the SILC protocol (aes-256-cbc) is used.
1633 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1635 * Removed lib/silcclient/ops.h file.
1637 Redefined parts of the SILC Client Library API. Created new
1638 file silcapi.h that deprecates the ops.h file and defines the
1639 published Client Library API. Defined also private message key
1640 API and channel private key API into the file.
1642 This is the file that the application must include from the
1643 SILC Client Library. Other files need not be included by
1644 the application anymore.
1646 * Added new key_agreement client operation callback and also
1647 defined the Key Agreement library API for the application.
1649 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1651 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1652 is used by clients to request key negotiation between another
1653 client in the SILC network. If the negotiation is started it
1654 is performed using the SKE protocol. The result of the
1655 negotiation, the secret key material, can be used for example
1656 as private message key.
1658 Implemented the Key Agreement payload into the files
1659 lib/silccore/silauth.[ch].
1661 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1663 * Redefined ciphers for the SILC protocol. Added some new ciphers
1664 and defined the key lengths for the algorithms. Changed the
1665 code accordingly. The default key length is now 256 bits.
1667 * Fixed SKE key distribution function silc_ske_process_key_material
1668 when the key length is more than 128 bits. The default key
1669 length in SILC is now 256 bits.
1671 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1672 to indicate unsupported algorithm.
1674 * Renamed rijndael.c to aes.c and all functions as well.
1676 * Fixed a long standing channel key setting bug in client library.
1677 Weird that it has never surfaced before.
1679 * Fixed bug in channel deletion. If the entire channel is removed
1680 then it must also delete the references of the channel entry
1681 from the client's channel list as the client's channel entry and
1682 the channel's client entry share same memory.
1684 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1686 * Implemented CONNECT and SHUTDOWN commands in the client.
1688 * Implemented CLOSE command to the client.
1690 * Added the function silc_idlist_find_server_by_name into the
1691 files silcd/idlist.[ch].
1693 Added the function silc_idlist_find_server_by_conn into the
1694 files silcd/idlist.[ch].
1696 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1698 * DIE command was renamed to SHUTDOWN. Updated the both code
1701 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1702 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1704 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1707 * Added function silc_server_create_connection function to create
1708 connection to remote router. My server implementation actually
1709 does not allow router to connect to normal server (it expects
1710 that normal server always initiates the connection to the router)
1711 so the CONNECT command is only good for connecting to another
1714 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1716 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1717 or some other client was kicked from the channel.
1719 Implemented the handling of the notify type to both client
1722 Implemented silc_server_send_notify_kicked to send the KICKED
1723 notify. It is used to send it to the server's primary router.
1725 * Implemented the KICK command into server and client.
1727 * Added `query' argument to the silc_idlist_get_client function
1728 to indicate whether to query the client from server or not if
1731 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1732 to indicate that the client is not channel founder.
1736 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1738 * Removed the rng context from SilcPacketContext structure and
1739 changed that the packet routine uses the Global RNG API.
1741 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1743 * Added support for quit message that client can "leave" on the
1744 channel when it quits the SILC. It is ditributed inside the
1745 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1747 Added silc_server_free_client_data that will take the
1748 signoff message as argument.
1750 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1752 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1754 * Updated parts of the protocol specification to keep it up
1757 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1759 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1760 payloads in one packet.
1762 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1763 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1764 use now the new List flag.
1766 * Also deprecated the following packet types: REPLACE_ID,
1767 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1769 * Added list support for Notify packet in server.
1771 * Added silc_server_send_notify_channel_change to send the
1772 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1773 the silc_server_send_replace_id.
1775 * Added silc_server_send_notify_nick_change to send the
1776 NICK_CHANGE notify type. Deprecates the function
1777 silc_server_send_replace_id.
1779 * Added silc_server_send_notify_join to send the JOIN notify type.
1780 Deprecates the function silc_server_send_new_channel_user.
1782 * Added silc_server_send_notify_leave to send LEAVE notify type.
1783 Deprecates the function silc_server_send_remove_channel_user.
1785 * Added silc_server_send_notify_cmode and
1786 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1787 types. Deprecates the silc_server_send_set_mode function.
1789 * Added SERVER_SIGNOFF notify type to indicate that server has
1790 quit. This means that all clients on the channel from that
1791 server will drop. This can be also used when netsplit happens.
1793 Deprecated REMOVE_ID packet type since it is not needed anymore
1796 Added silc_server_send_notify_server_signoff to send the
1797 SERVER_SIGNOFF notify type. Deprecates the function
1798 silc_server_send_remove_id.
1800 Added also silc_server_send_notify_signoff to send the
1801 SIGNOFF notify type.
1803 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1804 SILC protocol from this day on. Changed the protocol
1805 specification as well.
1807 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1808 notify type. It is used between routers to notify about
1809 topic changes on a channel.
1811 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1814 * Partly updated the protocol specification to comply with the
1815 changes now made. It is still though a bit outdated.
1817 * The JOIN notify type now takes one extra argument <Channel ID>.
1818 The packet used to be destined to the channel but now the
1819 JOIN type may be sent as list thus it is impossible to
1820 destine it to any specific channel. By adding this argument
1821 it is again possible.
1823 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1825 * Added CREDITS file. The CHANGES and CREDITS file will appear
1826 in the distribution as well.
1828 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1830 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1831 types in the server's silcd/packet_receive.c.
1833 * Implemented CMODE and CUMODE to work in router environment.
1835 * Fixed minor encoding and decoding buglet from the
1836 lib/silccore/silcmode.c.
1838 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1841 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1843 * Changed all SilcConfigServer* and silc_config_server* to
1844 SilcServerConfig* and silc_server_config*, respectively.
1847 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1849 * Associated the ID (client or server ID) to the Authentication
1850 Payload to avoid any possibility of forging. Updated the
1851 protocol specification and the code accordingly.
1853 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1855 * The RSA key length is now save to the RsaKey context in the
1856 key generation process in lib/silccrypt/rsa.c. The key length
1857 is now used to figure out the maximum size of the block allowed
1858 to be encrypted/signed.
1860 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1861 is equivalent to the silc_mp_mp2bin but does not allocate any
1864 * Changed silc_mp_mp2bin API to take length argument. If it is
1865 non-zero then the buffer is allocated that large. If zero, then
1866 the size is approximated using silc_mp_sizeinbase, which however
1869 * Created Global RNG API which is global RNG that application can
1870 initialize. After initializing, any routine anywhere in the
1871 code (including library) can use RNG without allocating a new
1872 RNG object. This was done to allow this sort of use of the
1873 RNG in code that has no chance to allocate RNG object. All
1874 applications currently allocate this and many routines in the
1875 library use this. Affected file lib/silccrypt/silcrng.[ch].
1877 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1878 it to use the Global RNG API.
1880 * Defined Authentication Payload into protocol specification that
1881 is used during SILC session to authenticate entities. It is
1882 used for example by client to authenticate itself to the server
1883 to obtain server operator privileges.
1885 Implemented this payload into the lib/silccore/silcauth.[ch].
1886 Implemented also routines for public key based authentication
1887 as the new protocol specification dictates.
1889 Moved definitions of different authentication methods from
1890 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1892 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1893 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1894 silc_pkcs_verify_with_hash functions into the file
1895 lib/silccrypt/silcpkcs.[ch].
1897 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1899 * The client entry's userinfo pointer must be always valid.
1900 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1901 will fail since it requires the userinfo. Now, the userinfo
1902 is allocated as "" if actual userinfo does not exist. Actually,
1903 it must exist and it is totally Ok to drop client connections
1904 that does not announce the userinfo. However, we will make
1905 this workaround for now.
1907 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1908 to return the remote port by socket.
1910 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1912 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1913 SILC_SERVER_PENDING_EXEC and added an new macro
1914 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1915 data or when error occurs while processing the pending command.
1917 Added new argument `destructor' into silc_server_command_pending
1918 and to the SilcServerCommandPending object. This destructor is
1919 now called after calling the pending callback or if error occurs
1920 immediately. If error occurs the actual pending callback won't
1921 be called at all - only the destructor. The destructor may be
1922 NULL if destructor is not needed.
1924 All this applies for client library code as well. Similar
1925 changes were made there as well for the pending commands.
1927 In the client, the application must now allocate the
1928 SilcClientCommandContext with the silc_client_command_alloc
1931 * Added reference counter to the SilcServerCommandContext. Added
1932 function silc_server_command_alloc and silc_server_command_dup
1935 Same type of functions added to the client library for the same
1938 * Removed the cmd_ident from IDListData away since it is now
1939 global for all connections. It is the command identifier used
1940 in command sending and with pending commands. The affected file
1943 * Added reference counter to the SilcSocketConnection objecet to
1944 indicate the usage count of the object. The object won't be
1945 freed untill the reference counter hits zero. Currently only
1946 server uses this, and client ignores it. The client must be
1947 set to use this too later. The affected files are
1948 lib/silccore/silcsockconn.[ch]. Added also the function
1949 silc_socket_dup to increase the reference counter.
1951 This was mainly added because it is possible that the socket
1952 is removed underneath of pending command or other async
1953 operation. Now it won't be free'd and proper DISCONNECTING
1954 flags, etc. can be set to avoid sending data to connection that
1955 is not valid anymore.
1957 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1958 the connection. After that it sets SILC_SET_DISCONNECTED.
1959 It is, however, possible that the socket data is not still freed.
1960 The silc_server_packet_process now checks that data is not
1961 read or written to connection that is DISCONNECTED. The socket
1962 get's freed when the reference counter hits zero.
1964 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1966 * Changed the client operation API: channel_message operation's
1967 `sender' is now the client entry of the sender, not the nickname
1968 and the `channel' is the channel entry, not the channel name.
1970 In the private_message operation the `sender' is now also the
1971 client entry of the sender not the nickname.
1973 Affected file is lib/silcclient/ops.h and all applications
1974 using the client operations.
1976 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1978 * Moved the calling of ops->connect() from connect_to_server_final
1979 into receive_new_id functin since that is the point when the
1980 client is actually allowed to send traffic to network. The
1981 affected file is lib/silcclient/client.c.
1983 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1985 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1986 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1987 (if needs broadcasting) instead of broadcasting the packets one
1988 by one which would make a burst in the network traffic.
1990 * Added `broadcast' argument to the functions in silcd/server.[ch]
1991 silc_server_create_new_channel[_with_id] to indicate whether
1992 to send New Channel packet to primary router.
1994 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1996 * Added new function into the silcd/server.[ch] files:
1997 silc_server_create_new_channel_with_id to create new channel with
1998 already existing Channel ID.
2000 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2001 lib/silccore/silcpacket.h. This packet is used t send list of
2002 Set Mode payloads inside one packet. Server uses this to set
2003 the modes for the channels and clients on those channels, that it
2004 announced to the router when it connected to it. The protocol
2005 specification has been updated accordingly.
2007 * The silc_server_new_channel did not handle the packet coming
2008 from normal server as it normally does not send that. However,
2009 when it announces its channels it does send it. Implemented
2010 the support for that.
2012 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2013 into the file lib/silccore/id.h.
2015 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2017 * Fixed memory leaks in the functions silc_idlist_del_client,
2018 silc_idlist_del_channel and silc_idlist_del_server in the file
2019 silcd/idlist.c. All of those leaked like a sieve.
2021 * Fixed some small memory leaks in the client's function
2022 silc_client_notify_by_server.
2024 * Added functions into silcd/server.c: silc_server_announce_clients,
2025 silc_server_announce_channels and silc_server_announce_server.
2026 These functions are used by normal and router server to announce
2027 to its primary router about clients, channels and servers (when
2028 router) that we own. This is done after we've connected to the
2031 These functions effectively implements the following packet types:
2032 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2033 and SILC_PACKET_NEW_ID_LIST.
2035 * Added new functions into the silcd/packet_receive.[ch]:
2036 silc_server_new_id_list, silc_server_new_channel_list and
2037 silc_server_new_channel_user_list to handle the incoming
2038 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2040 * Added support of changing Channel ID in the function
2041 silc_server_replace_id. If the server that announces a channel
2042 to the router already exists in the router (with same name but
2043 with different Channel ID), router is responsible to send
2044 Replace ID packet to the server and force the server to change
2045 the Channel ID to the one router has.
2047 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2048 client that the Channel ID has been changed by the router. The
2049 normal server sends this to the client. Client must start using
2050 the new Channel ID as the channel's ID.
2052 Implemented handling of this new type into lib/silcclient/client.c
2053 into the function silc_client_notify_by_server.
2055 * Added new function silc_idlist_replace_channel_id into the files
2056 silcd/idlist.[ch] to replace the Channel ID.
2058 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2060 * Call silc_server_command_identify_check always when processing
2061 the IDENTIFY command in silcd/command.c
2063 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2065 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2066 send keepalive packets. The packet can be sent by clients,
2067 servers and routers.
2069 Added function silc_socket_set_heartbeat into the file
2070 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2071 If not set, the heartbeat is not performed. The actual
2072 heartbeat is implemented in the low level socket connection
2073 library. However, application is responsible of actually
2076 Added silc_server_send_heartbeat to send the actual heartbeat
2077 packet into silcd/packet_send.[ch]. Server now performs
2078 keepalive with all connections.
2080 * Added silc_task_get_first function into lib/silcutil/silctask.c
2081 to return the timeout task with shortest timeout. There was a bug
2082 in task unregistration that caused problems. TODO has been
2083 updated to include that task system must be rewritten.
2085 * The client library will now resolve the client information when
2086 receiving JOIN notify from server for client that we know but
2087 have incomplete information.
2089 * Rewrote parts of silc_server_remove_from_channels and
2090 silc_server_remove_from_one_channel as they did not remove the
2091 channel in some circumstances even though they should've.
2093 * Encryption problem encountered in server:
2095 The LEAVE command used to send the Channel Key packet to the
2096 router immediately after generating it. However, the code
2097 had earlier sent Remove Channel user packet but not immediately,
2098 ie. it was put to queue. The order of packets in the router
2099 was that Channel Key packet was first and Remove Channel User
2100 packet was second, even though they were encrypted in the
2101 reverse order. For this reason, MAC check failed. Now, this
2102 is fixed by not sending the Channel Key packet immediately but
2103 putting it to queue. However, this is more fundamental problem:
2104 packets that are in queue should actually not be encrypted
2105 because packets that are sent immediately gets encrypted
2106 actually with wrong IV (and thus MAC check fails). So, packets
2107 that are in queue should be encrypted when they are sent to
2108 the wire and not when they put to the queue.
2110 However, the problem is that the current system has not been
2111 designed to work that way. Instead, the packet is encrypted
2112 as soon as possible and left to the queue. The queue is then
2113 just purged into wire. There won't be any fixes for this
2114 any time soon. So, the current semantic for packet sending
2117 o If you send packet to remote host and do not force the send
2118 (the packet will be in queue) then all subsequent packets to the
2119 same remote host must also be put to the queue. Only after the
2120 queue has been purged is it safe again to force the packet
2123 o If you send all packets immediately then it safe to send
2124 any of subsequent packets through the queue, however, after
2125 the first packet is put to queue then any subsequent packets
2126 must also be put to the queue.
2128 Follow these rules and everything works fine.
2130 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2132 * Added new function silc_server_remove_clients_by_server to
2133 remove all client entries from ID list when the server connection
2134 is lost. In this case it is also important to invalidate all
2135 client entires as they hold the invalid server entry. This
2136 fixes fatal bug when server has lost connection and will reconnect
2139 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2141 * Made some sanity checks to silc_server_daemonise like to check
2142 whether the requested user and group actually exists.
2144 * Added sanity check to SKE's silc_ske_responder_finish to check
2145 that the public and private key actually is valid.
2147 * Invalidate the client's nickname when receiving Replace ID
2148 packet and the Client ID is being replaced. This means that the
2149 server will query the nickname if someone needs it (client)
2152 * Sort the ID Cache in client library when the ID Cache data
2153 has changed (needs sorting).
2155 * Do not allow for SILC client to create several connections to
2156 several servers. The client does not support windows right now
2157 and generating multiple connections causes weird behaviour.
2159 Irssi-silc client does support windows and can handle several
2160 connections without problems, see: www.irssi.org and SILC plugin.
2162 * Fixed some places where client was added to the IDList. The
2163 rule of thumb is following (in order to get everything right):
2164 If the client is directly connected local client then the
2165 `connection' argument must be set and `router' argument must be
2166 NULL to silc_idlist_add_client function. If the client is not
2167 directly connected client then the `router' argument must
2168 bet set and the `connection' argument must be NULL to the
2169 silc_idlist_add_client function.
2171 * The funtion silc_server_packet_send_local_channel actually did
2172 not check whether the client was locally connected or not. It
2173 does that now. Fixed a bug related to LEAVE command.
2175 * Fixed Remove Channel User payload parsing bug in server's
2176 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2178 * The server's silc_server_save_channel_key now checks also the
2179 global ID list for the channel as it might not be in the local
2180 list. Fixed a bug related to LEAVE command.
2182 * Is this the end of the [<unknown>] buglet that has been lurking
2183 around for a long time? A little for loop fix in server's
2184 silc_server_command_whois_parse that is used by both IDENTIFY
2185 and WHOIS command. At least, this was a clear bug and a cause
2186 of one type of [<unknown>] buglet.
2188 * WHOIS and IDENTIFY commands call the function
2189 silc_server_command_[whois/identify]_check function even if
2190 we are not router server.
2192 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2194 * Added --with-gmp configuration option. If set the GMP
2195 is always compiled in the SILC source tree. If not set then
2196 it is checked whether the system has the GMP3 installed. If
2197 it has then the GMP won't be compiled (the system's headers
2198 and library is used), if it doesn't have it then the GMP is
2199 compiled in the SILC source tree.
2201 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2203 * Changed RSA private exponent generation to what PKCS #1
2204 suggests. We try to find the smallest possible d by doing
2205 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2206 not security fix but optimization.
2208 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2210 * Added new config entry [Identity] to fork the server and run
2211 it as specific user and group. A patch from Bostik.
2213 * Imported Dotconf configuration library into lib/dotconf.
2214 This will be used to create the SILC configuration files later.
2215 It will appear in the distsribution after this commit.
2217 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2219 * A big code auditing weekend happening. Auditing code for
2220 obvious mistakes, bugs and errors. Also, removing any code
2223 Removed files for being obsolete:
2225 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2226 inline in the file lib/silcutil/silcbuffer.h)
2228 o lib/silcutil/silcbufutil.c (the header has inline versions)
2230 Changed code to fix possible error conditions:
2232 o The buffer formatting routines now check that the destination
2233 buffer really has enough space to add the data. This applies for
2234 both buffer formatting and unformatting
2235 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2236 unformatting was changed to accomodate following rules:
2237 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2238 sent to the function while XXX_*STRING will not allocate or copy
2239 the data into the buffer. Instead it sets the pointer from the
2240 buffer into the pointer sent as argument (XXX_*STRING used to
2241 require that the pointer must be allocated already). This change
2242 makes this whole thing a bit more consistent and more optimized
2243 (note that the data returned in the unformatting with XXX_*STRING
2244 must not be freed now). The routines return now -1 on error.
2246 o Tried to find all code that use buffer_format and buffer_unformat
2247 and added return value checking to prevent formatting and
2248 especially unformatting errors and possible subsequent fatal
2251 o Changed ske->x and ske->KEY to mallocated pointers in
2252 lib/silcske/silcske.h. Fixed possible data and memory leak.
2254 o Added return value checking to all *_parse* functions. Fixed
2255 many memory leaks as well.
2257 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2258 so that buffer overflows would not happen. All code now also
2259 checks the return value as it can fail.
2261 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2263 * Added reconnection support to server if the normal server looses
2264 its connection to the router (for example if router is rebooted).
2265 The server performs normal reconnection strategy implemented
2266 to the server. Affected file silcd/server.c.
2268 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2270 * Added new packet type SILC_PACKET_SET_MODE that is used to
2271 distribute the information about changed modes (for clients,
2272 channels and clients channel modes) to all routers in the
2273 network. Updated the protocol specification accordingly.
2275 Added functions into silcd/packet_send.c and
2276 silcd/packet_receive.c: silc_server_send_set_mode,
2277 silc_server_set_mode.
2279 Added new files silcmode.[ch] into lib/silccore that implements
2280 the encoding and decoding of Set Mode Payload. Added new type
2281 SilcSetModePayload. Moved the definitions of different modes
2282 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2284 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2286 * Oops, a little mistake in server's connection authentication
2287 protocol. The protocol is not ended with FAILURE but with
2288 SUCCESS if the authentication is Ok. :) Affected file is
2291 * Implemented NICK_CHANGE notify handling in server in the file
2292 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2293 the local clients on the channel. After the changing nickname
2294 in router environment snhould work and the [<unknown>] nickname
2295 should appear no more.
2297 The silc_server_replace_id function that receives the Replace ID
2298 payload now sends the NICK_CHANGE notify type also in the file
2299 silcd/packet_receive.c
2301 * Changed WHOIS and IDENTIFY command to support the maximum amount
2302 of arguments defined in protocol specs (3328 arguments). This
2303 fixed a bug that caused problems when there were more than three
2306 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2308 * Added extra parameter, command identifier, to the
2309 silc_client_send_command so that explicit command identifier
2312 Changed that ID list routines uses specific command identifier
2313 when sending WHOIS/IDENTIFY requests to the server so that they
2314 can be identified when the reply comes back.
2316 Affected files lib/silcclient/command.[ch],
2317 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2319 * Added `sender' argument to silc_server_packet_send_to_channel
2320 to indicaet the sender who originally sent the packet to us
2321 that we are now re-sending. Ignored if NULL. Affected file
2322 silcd/packet_send.[ch].
2324 * Added some server statistics support in silcd/server_internal.h
2325 SilcServerStatistics structure and around the server code. Also
2326 send some nice statistics information when client is connecting
2329 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2331 * Fixed channel ID decoding in server's JOIN command reply in
2332 silcd/command_reply.c
2334 * Fixed braodcasting of replace ID payload to not to send it if
2335 we are standalone server in silcd/packet_receive.c.
2337 * Fixed all channel message sending routines to not to send
2338 packets to clients that has router set, since they are routed
2339 separately in the same function earlier. Affects file
2340 silcd/packet_send.c and all channel packet sending functions.
2342 * In USERS reply, res_argv[i] are not allocated, the table
2343 is allocated. Thus changed that free the table, not its
2346 * In server's whois_check and identify_check if the client is
2347 locally connected do not send any WHOIS commands - they are not
2350 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2352 * Fixed some minor bugs in client when sending WHOIS command. The
2353 arguments was in wrong order.
2355 * Removed statis function add_to_channel from server in
2356 silcd/command.c that was previously used with the joining but
2359 * Tested USERS command in router environment successfully with two
2360 routers, two servers and two clients.
2362 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2364 * Reorganized the USERS command and command reply in client library
2365 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2366 When the command is given by user we register a pending command
2367 callback that will reprocess the command after the reply has been
2368 received from the server. When reprocessing the packet we then
2369 display the information. Thus, the USERS information is displayed
2370 now in the command callback instead of in the command reply
2371 callback. The processing of the command is same as previously
2372 when server has sent the command reply in the JOINing process.
2374 * Added to USERS command in silcd/command_reply.c to join the client,
2375 we didn't use to know about, to the channel after we've created
2376 a client entry for it. Also, for clienet we did know already still
2377 check whether it is on the channel or not and add it if not.
2379 * Removed silc_server_command_join_notify as the function and its
2382 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2384 * Changed the client's pending command handling to the same as the
2385 server's pending command handling. It is also now possible to
2386 execute command reply functions from other command reply
2387 function as the function callbacks for commands and command
2388 replies are one and same. The pending commands are not static
2389 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2390 in client connection context. Thus, pending commands are server
2391 connection specific as it is convenient.
2393 Changed the function silc_client_command_pending and
2394 silc_client_command_pending_del and added new function
2395 silc_client_command_pending_check. Removed the
2396 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2399 * Added cmd_ident, current command identifier, to the client
2400 connection context in lib/silcclient/client.h to keep track on
2401 command identifiers used in command sending. Client's command reply
2402 function handling now supports the mandatory command identifiers.
2404 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2405 funtions in client to fully support pending command callbacks.
2407 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2408 as one of the arguments to the application in the command reply
2411 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2412 before first releasing SILC but came back. Now it is removed again
2413 and should come back nomore. The FORWARDED flag was used only
2414 by the JOINing procedure by forwarding the command packet to router.
2415 Now, the JOINing procedure has been changed to more generic (due
2416 to various router environment issues) and FORWARDED is not needed
2417 anymore for anything. The protocol specification is yet to be
2420 Now, removed silc_server_packet_forward from server and the flag
2421 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2423 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2425 * Renamed NAMES command to USERS command. The NAMES was named that
2426 due to historical reasons. Now it is renamed. Also, rewrote
2427 parts of the USERS command. The nickname list is not sent anymore
2428 by the server. Only Client ID and mode lists are sent in the USERS
2429 command. Changed this also to the protocol specification.
2431 The client now resolves the names and stuff after it receives
2432 the USERS list from the server when joining to the channel.
2434 * WHOIS and IDENTIFY commands has been changed to support multiple
2435 Client ID's per command. One can now search for multiple users
2436 in the network by sending only one WHOIS or IDENTIFY command.
2437 Changed the code and the protocol specifications.
2439 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2440 uses silc_server_command_whois_parse to parse the request. */
2442 * If normal server, do not parse the WHOIS and IDENTIFY requests
2443 before sending it to the router. Saves some time.
2445 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2447 * Fixed JOIN command on client library. Wrong number of arguments
2448 used to crash the client.
2450 * Added silc_server_channel_has_global function to check whether
2451 channel has global users or not.
2453 * Added silc_server_channel_has_local function to check whether channel
2454 has locally connected clients on the channel.
2456 * The silc_server_remove_from_one_channel now checks whether the
2457 channel has global users or not after given client was removed from
2458 the channel. It also checks whether the channel has local clients
2459 on the channel anymore. If it does not have then the channel entry
2460 is removed as it is not needed anymore.
2462 * The silc_server_notify now checks on JOIN notify whether the joining
2463 client is one of locally connected or global. If it is global then
2464 the channel has now global users on the channel and that is marked
2465 to the channel entry. Also, it now saves the global client to
2466 global list who is joining and JOINs it to the channel. This is
2467 for normal server, that is.
2469 Changed silc_server_send_notify_on_channel,
2470 silc_server_packet_relay_to_channel and
2471 silc_server_packet_send_to_channel check if we are normal server
2472 and client has router set (ie. global client) do not send the
2473 message to that client, as it is already routed to our router.
2475 * Implemented LEAVE notify type handling in silc_server_notify
2478 * Tested LEAVE command in router environment successfully. Tested
2479 with two routers, two servers and two clients.
2483 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2485 * Implemented SIGNOFF notify type handling in silc_server_notify
2488 * silc_server_remove_id now removes the client entry from all channels
2489 it has joined and thusly sends SIGNOFF notify type.
2491 * Rewrote the NAMES list generation in server by removing two excess
2492 loops. The lists are created now inside one loop.
2494 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2496 * silc_server_remove_channel_user checks now also global list
2497 for channel and client.
2499 * silc_server_new_channel_user checks now both local and global
2500 list for channel and client. Fixed a bug in client id decoding.
2501 Used to decode wrong buffer.
2503 * silc_server_channel_message checks now both local and global
2504 list for channel entry.
2506 * Tested channel joining (hence JOIN) in router environment
2507 successfully. Tested with two routers, two servers and two
2510 * Tested channel message sending in router environment successfully.
2512 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2514 * Added silc_server_save_channel_key into server.[ch] to save the
2515 received channel key in Channel Key payload processing. It is
2516 also used in JOIN command reply handling.
2518 Equivalent function silc_client_save_channel_key added into
2519 client.[ch] into client library.
2521 * Changed JOIN command reply to send information whether the channel
2522 was created or not (is existing already) and the channel key
2523 payload. Changed protocol specs accordingly.
2525 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2526 the request was sent by ID and not by nickname. Crashed on
2529 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2531 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2532 now correctly save the received data.
2534 * silc_server_free_sock_user_data now notifies routers in the
2535 network about entities leaving the network.
2537 At the same time implemented functions silc_server_remove_id
2538 and silc_server_send_remove_id to receive and send REMOVE_ID
2539 packets. The packet is used to notify routers in the network
2540 about leaving entities. The ID removed will become invalid in
2543 * Added function silc_idlist_del_server into server. Removes and
2544 free's server entry from ID list.
2546 * silc_server_private_message function now checks, if we are router,
2547 that the destination ID really is valid ID, naturally.
2549 * In router when NEW_ID packet is received (for new client) the
2550 hash of the Client ID is saved in the ID Cache but the
2551 client->nickname is set to NULL, instead of putting the hash
2554 IDENTIFY command now also checks that client->nickname must be
2555 valid. If it is not if will request the data from the server who
2556 owns the client. Added new function
2557 silc_server_command_identify_check.
2559 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2560 to set the command to already allocated Command Payload.
2562 * Tested private message sending in router environment with two
2563 routers, two servers and two clients. Fixed minor bugs and now
2566 * Fixed segfault from client's NAMES command. Used to crash if
2569 * Forwarded packets must not be routed even if it is not destined
2570 to the receiver. Changed server code comply with this.
2572 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2574 * Added `require_reverse_mapping' boolean value to ServerParams
2575 structure. If TRUE (not default) the server will require that
2576 the connecting host has fully qualified domain name.
2578 If the reverse mapping is not required and hostname could not be
2579 found the IP address is used as hostname.
2581 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2583 * Implemented version string checking to both client and server.
2584 The check is incomplete currently due to the abnormal version
2585 strings used in development version of SILC.
2587 * Changed all command functions in server to use the new
2590 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2592 * Changed char *data to unsigned char *data in ID Cache system to
2593 support binary data as ID Cache data. Changed code to support
2594 binary data in lib/silccore/idcache.c.
2596 * Renamed silc_server_packet_relay_command_reply to
2597 silc_server_command_reply as it is normal packet receiving
2598 function. Rewrote the function to accept command replys for
2599 servers and not only for clients.
2601 * Mark remote router always as registered server if we are connecting
2602 to it. Otherwise, commands sent by the router to us are ignored.
2604 * All ID List find routines now returns the ID Cache Entry pointer
2605 as well if requested.
2607 * WHOIS command works now in router environment, tested with two
2608 routers, two servers and two clients.
2610 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2611 in router environment (as it is almost equivalent to WHOIS) but
2612 hasn't been tested thoroughly. Added new functions:
2614 silc_server_command_identify_parse
2615 silc_server_command_identify_send_reply
2616 silc_server_command_identify_from_client
2617 silc_server_command_identify_from_server
2619 * Disabled route cache adding because adding two different ID's with
2620 same IP replaces the old cache entry thus giving wrong route.
2621 The entry->router->connection is always the fastest route anyway
2622 so route cache may not be needed. Of course, new routes maybe
2623 established after receiving the ID when the entry->router->connection
2624 might not be anymore the most optimal.
2626 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2628 * Add route cache for received ID for fast routing.
2630 * Added silc_server_packet_route to route received packet on router
2631 that is not destined to us.
2633 * Renamed silc_server_get_route to silc_server_route_get.
2635 * Added id_string and id_string_len fields into SilcServer to
2636 include encoded ServerID for fast comparing without excess
2637 encoding of the ID's.
2639 * Cleaned up WHOIS command on server side. Added following static
2642 silc_server_command_whois_parse
2643 silc_server_command_whois_check
2644 silc_server_command_whois_send_reply
2645 silc_server_command_whois_from_client
2646 silc_server_command_whois_from_server
2648 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2649 arguments in command replies. All command functions should be
2650 updated to use this macro.
2652 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2654 * Minor typo fixes on command reply handling on server.
2656 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2658 * Added silc_server_command_add_to_channel internal routine to add
2659 the client to the channel after router has created the channel and
2660 sent command reply to the server.
2662 * Added generic silc_server_send_command to send any command from
2665 * Use static buffer with ID rendering instead of duplicating data.
2667 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2669 * Fixed a channel user mode bug when joining to a channel server gave
2670 everybody channel founder rights, oops.
2672 * We mark ourselves as the router of the incoming server connection
2673 if we are router ourselves. This way we can check in some packet
2674 sending functions whether it is locally connected server. For
2675 incoming router connections we put NULL.
2677 * For router sending packets locally means now always sending the
2678 packet cell wide; to local clients and local servers. For normal
2679 server sending packet locally means sending it to only local
2682 * Fixed the JOIN command to really work in router environment. If the
2683 channel is created it is always created by the router. Router is
2684 also responsible of making the initial joining to the channel,
2685 sending JOIN notify to the sending server and distributing
2686 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2687 does not exist server doesn't do anything else but forward the
2688 command to the router which performs everything.
2690 * Added silc_server_send_channel_key function to send the Channel Key
2693 * Added silc_server_create_channel_key to create new channel key. The
2694 channel key is now re-generated everytime someone joins or leaves
2695 a channel, as protocol dictates. Note: channel->key_len is the
2698 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2700 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2701 packet_receive.[ch] to separate packet sending and receiving
2702 routines. The server.[ch] now includes everything else including
2703 actual packet processing (writing and reading data) and other
2706 Renamed silc_server_private_message_send_internal to
2707 silc_server_send_private_message. The routine is still though
2708 used only to relay private messages as server does not send
2709 private messages itself.
2711 Renamed silc_server_new_channel to silc_server_create_new_channel
2712 and added new function sicl_server_new_channel that handles the
2713 incoming New Channel packet. Added also new sending function
2714 silc_server_send_new_channel to send New Channel Payload.
2716 * Added new function silc_server_notify to process incoming notify
2717 packet to the server/router. Server may then relay the notify
2718 to clients if needed.
2720 * Added new function silc_server_new_channel_user to process incoming
2721 New Channel User packet. Router will redistribute the packet and
2722 send JOIN notify to its local clients and locally connected servers
2723 if needed. Normal server will send JOIN notify to its local client
2724 on same channel when received this packet. Added also corresponding
2725 sending function silc_server_send_new_channel_user to sent the
2728 * Added boolean route argument to send_notif_to_channel and
2729 packet_send_to_channel functions to attempt to route the packet
2730 if it is TRUE and send only locally if it is FALSE.
2732 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2734 * silc_server_replace_id now broadcasts the received replace ID
2735 packet if it is not broadcast packet already. The router must
2736 broadcast to inform other routers about changed ID.
2738 * Added backpointer to server's router into SilcServer context in
2739 silcd/server_internal.h.
2741 * Fixed silc_server_packet_broadcast to send correct broadcast
2744 * The channel key is now distributed to the local client as soon
2745 as it is received from the router (in router environment) so that
2746 no other packet may be sent for the channel until client has
2749 * silc_server_remove_channel_user now broadcasts the received
2750 Remove Channel User packet if it is not broadcast packet already.
2751 The router must broadcast to inform other routers about removed
2754 * Added users field into SilcPacketContext that is a reference count
2755 of the context. One can increase the reference count by calling
2756 silc_packet_context_dup which is now changed to just increase the
2757 reference count instead of duplicating the data. The reference
2758 count is decresed by calling silc_packet_context_free that will
2759 free the data after the reference count hits zero.
2761 For now on the packet context and everything allocated into it
2762 (including the raw packet from network) must be freed by calling
2763 the new silc_packet_context_free function. Added also new function
2764 silc_packet_context_alloc that must be used now to allocate the
2765 context. This also means that if a routine is asynchronous from
2766 silc_[client/server]_packet_parse_type the packet context must
2767 be duplicated by calling silc_packet_context_dup. Otherwise it
2768 gets free'd after silc_[client/server]_packet_parse_type returns.
2769 Also, one must remember that if packet is duplicated then its
2770 reference count must be decresed by calling the free function as
2771 many times as it was duplicated.
2773 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2774 from both client and server.
2776 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2778 * Made joining to a channel working in router environment.
2780 * Cleaned up JOIN command on server side and create function
2781 silc_server_command_join_channel internal routine to make the
2784 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2786 * Changed silc_command_pending list to SilcDList. Also, added
2787 `ident' field to SilcServerCommandPending structure to identify
2788 the reply and to call correct callback.
2790 Added silc_server_command_pending_check function to replace the
2791 corresnponding macro. The silc_command_pending list is not
2794 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2795 to set identifier to previously allocated Command Payload. It
2796 is used to set identifier for command when resending Command
2799 * Added silc_command_payload_encode_payload to encode Command
2800 Payload buffer from SilcCommandPayload structure.
2802 * Added silc_argument_payload_encode_payload to encode Argument
2803 payload buffer from SilcArgumentPayload structure.
2805 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2807 * Changed WHOIS command to support router connection on server side.
2808 The whois request is always sent to router unless the server is
2809 standalone server. After server has received the reply from the
2810 router will it send the reply to the client.
2812 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2813 broadcast received broadcast packet. The function is used only
2814 by router. The broadcast packet is always sent to the router's
2817 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2818 render given ID to printable string, for log files for example.
2820 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2822 * Made basic router to router connections working. At least they
2823 can now connect to each other but nothing really works the way
2824 they are supposed - yet.
2826 * Added new initiator token to RouterConnection configuration
2827 file in silcd/serverconfig.[ch]. It is used to tell whether we
2828 are the initiator to the remote router or whether we'll expect
2829 the other end to connect.
2831 * Moved registering of listener task to silc_server_init, hence
2832 the server starts listenning as soon as it is run, even if it
2833 does not have connections to other routers. Let's see how well
2836 * Changed default connection retry timeouts for more suitable in
2839 * Removed cipher and such arguments from silc_idlist_add_client
2840 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2841 Added new function silc_idlist_add_data to add the keys and stuff
2844 * Added SilcIDListData structure and added it to SilcClientEntry
2845 and SilcServerEntry as their first field in the structure. This
2846 way we can explicitly cast the ID entries to the SilcIDListData
2847 structure and get common data for the entries. In past, we had
2848 to first check what type of connection it is and then cast it to
2849 correct ID entry type. Now, we can directly cast the opaque
2850 pointer to the SilcIDListData (no matter what ID entry it actually
2851 is) and get the data needed.
2853 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2855 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2856 in some circumstances even if threre were timeout tasks, though not
2857 IO tasks, but tasks anyway. Now fixed.
2859 * Defined SilcServerConnection structure to hold connection specific
2860 stuff about directly connected servers and routers. The definition
2861 is currently in silcd/server_internal.h. I thought about having
2862 a bit more important role fro this struct but for now it is used
2863 only when connecting to other server (or router actually).
2865 * Added connecting retry support in server when connecting to
2866 router(s). The retry feature implement exponential backoff
2867 algorithm. Also, added SilcServerParams structure to hold default
2868 parameters for server. For now, it include these retry settings
2869 and are hard coded. After server is moded to be as Silc Server
2870 Library this structure will be more important.
2872 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2874 * Changed client librarys channel->clients table to SilcList and
2875 changed code accordingly.
2877 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2879 * Changed client's channel table to SilcList and changed code
2880 accordingly. Also changed SilcChannelClientEntry to include back-
2881 pointer to the channel so that client entry can use that structure
2882 as list as well and we have fast cross-reference to the channel.
2883 This change dramatically decreased the complexity of channel
2884 handling with client entry and vice versa (removed one extra
2885 loop when searching for channel entry from many functions).
2887 * Changed server->sim from table to SilcDList and changed code
2890 * NAMES command can now be used from user interface. It will show
2891 the user list on the channel, neatly.
2893 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2894 Code now saves realname of the user if it becomes available.
2896 * Renamed configure.in to configure.in.pre and made ./prepare
2897 script to automatically add correct version string to
2898 configure.in which it creates from configure.in.pre.
2900 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2902 * NAMES command reply now shows users mode with the nickname when
2905 * Moved silc_client_ch[u]mode[_char] functions from
2906 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2907 place sucks, they are utility functions and should be in some
2910 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2912 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2915 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2919 * Added TRQ (efficient deque and list library) into lib/trq. This is
2920 a very good list library that is currently used in the SILC. Defined
2921 SilcList API over the library because I didn't like the API very
2922 much. See lib/trq/silclist.h for the API and examples of how to
2923 use the API. Fixed various places in the code to use the new
2924 SilcList API. The SilcList is meant for lists that has a structure
2925 already defined as a list. It is not suitable to add just some
2926 context to the list (in TRQ, the context is the list actually).
2928 So, I defined SilcDList that can be used for the purpose where
2929 predefined list structure does not exit. This can be used as
2930 such list. Now some context just can be added to the SilcDList.
2931 Currently this list is not used in the SILC just yet, though there
2932 are a lot places where this can replace dynamically allocated
2933 tables and I will fix these places, later, to use SilcDList.
2934 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2935 and use TRQ internally).
2937 Also fixed some annoying warning messages that the original TRQ
2938 code generated. Also minor changes to TRQ's Makefile.in.
2940 * Added support for querying by Client ID to both WHOIS and
2941 IDENTIFY commands into server, as required by the protocol.
2943 * Removed method function pointers from SilcBuffer structure. They
2944 weren't used to anything and just increased the context size for
2945 no good reason. This change also made silc_buffer_alloc and
2946 silc_buffer_free functions inline functions.
2948 * Disabled command flooding detection support until it's fixed so
2949 that it accepts commands in but does not execute them more than once
2952 * Added silc_net_localhost(), to return local hostname, into
2953 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2954 that must be initialized before calling silc_client_init.
2956 * Added new function: silc_server_send_notify_on_channels to send
2957 notify messages to all channels client has joined. It is assured
2958 that the message is sent only once per client.
2960 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2961 lib/silcutil/silcutil.[ch] as silc_format function. The new
2962 function is generic and is used by server as well, not only by
2963 the logging routines.
2965 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2966 the provided version string was not acceptable. Added new function:
2967 silc_ske_check_version into lib/silcske/silcske.h. The function
2968 must be implemented by the application (client or server) and it
2969 does not reside in the SKE library. The function checks the version
2970 string remote end sent.
2972 * Added back pointers (to opaque context and to SilcSocketConnection)
2973 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2975 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2976 duplicate packet context structure.
2978 * Changed `notify' client operation to send same arguments as client
2979 receives from server except for ID's. ID's are mapped to correct
2980 ID entry and that is returned. Also, if channel entry is not sent
2981 by server but the notify is for channel the channel entry is sent
2982 to application (otherwise application doesn't know that it is for
2983 channel (library gets it from packet's Destination ID)).
2985 * Added silc_client_remove_from_channels into client library to
2986 remove a client from all channels it has joined to. Used when
2987 received SIGNOFF notify from server. Added also new function
2988 silc_client_replace_from_channels to replace old ID entry with
2989 new ID entry on all channels. Used when received NICK_CHANGE
2992 * Fixed ID Cache list handling in silc_idlist_get_client in
2993 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2994 to get (or query) client by ID.
2996 * Updated TODO list.
2998 * Added connection authentication status message defined by the
2999 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3000 support for these into the code in client and server side.
3002 * Added generic function silc_client_send_command to send any command
3003 with variable argument list. Application should use this function
3004 to send commands if the command functions provided by the library
3005 does not suite for the application's user interface needs.
3007 * Added new `failure' client operation. Application is notified about
3008 received failure packet if client is executing a protocol. In this
3009 case the protocol's execution has failed.
3011 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3012 is required by the protocol.
3014 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3015 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3018 * Added status flag to SilcSKE object to indicate realtime status
3019 of the SKE protocol.
3021 * Application receives now exactly same command reply arguments as
3022 the library receives from server. However, if ID is received the
3023 corresponding ID entry is returned to the application (eg. Client
3024 ID is mapped to correct SilcClientEntry entry and that is returned).
3025 Changed command_reply client operation due to this change.
3027 * Changed all ID's in commands and in command replys as ID Payloads.
3028 Change affected both client and server side codes.
3030 All ID's sent in SILC network (with execption of ID's in SILC
3031 Packet header) are sent in ID Payload to support variable length
3034 * Server now notifies nick changes and notifies all clients on
3035 the channels about the new nickname (about the new Client ID,
3038 * Implemented CMODE command to change channel modes. Supports all
3039 channel modes defined by the protocol specs except ban and invite
3040 lists. (Also, private channel key mode is supported but support for
3041 setting private channel key in client is missing, thus, this mode
3042 has no effect on client side (except that server requires that the
3043 client uses private channel key and normal channel traffic does not
3046 Also, invite mode works per se, but INVITE command does not work
3047 yet correctly, so you can set channel as invite only channel but
3048 inviting clients to the channel does not work (it is yet to be
3049 thought what's the best way to do it).
3051 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3052 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3053 Implemented CUMODE command to change user's mode on the channel.
3054 Supports all modes defined by the protocol specs.
3056 * Added NAMES command reply to return users modes on the channel.
3058 * Removed unnecessary and slow ciphers from lib/silccrypt.
3060 * Set SO_KEEPALIVE option to connection sockets by default.
3062 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3064 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3065 redefined the Notify Payload into protocol specs.
3067 * Added silc_id_payload_parse_id to get ID directly from raw
3070 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3072 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3073 accept searching by Client ID as well.
3075 * Added support for LEAVE and SIGNOFF notify types in client library.
3077 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3078 to parse ID Payload from raw data.
3080 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3082 * Added flags parameter into silc_ske_assemble_security_properties
3083 function in lib/silcske/silcske.[ch].
3085 * Changed notify client operation to fit better for notify messages
3086 sent by server. The notify payload received from server is now
3087 passed to the application (after parsing it to SilcNotifyPayload).
3088 It is application's responsibility to retrieve the arguments
3089 from the payload and show the message the way it wants. The message
3090 sent by server is implementation specific.
3092 * Changed public keys to comply with the protocol specification.
3093 Old public keys are not supported anymore and are not compatible.
3095 * Removed nickname from Channel Payload as the latest draft removed
3096 it. The client must resolve the nickname from the NAMES command
3097 reply received when it joined the channel.
3099 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3101 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3103 * Fixed some errors in protocol specification drafts.
3105 * Created lib/silccore/silcnotify.c to implement Notify Payload
3106 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3107 generic payloads described by protocol specifications. The file
3108 includes implementations for ID Payload and Argument Payload.
3110 * Changed Command Payload implementation to use the new Argument
3111 Payload. Changed command_xxxx_payload to command_payload_xxxx
3112 to comply with SILC coding conventions.
3114 * Added suppport for Argument Payload handling in Notify Payload
3115 implementation as protocol requires it. Added the new support
3116 into server and client lib as well.
3118 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3120 * Added support for multiple nicknames on same channel. [n] is
3121 added locally to the nickname if there are more than one same
3122 nicknames on the channel.
3124 * Server now sends all nicknames that matched WHOIS request.
3125 Client also shows the list received from server.
3127 * Added TOPIC command to client side. User can now set and show
3128 current topic on channel.
3130 * Added MOTD command to client and server. Also, server sends the
3131 motd when client connects to the server.
3133 * Changed version strings to comply ISO 8601.
3135 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3137 * Fixed protocol error handling in client library. It should now
3138 cope even if the SKE fails for some reason.
3140 * Made new protocol specification drafts for submitting to IETF.
3142 * Implemented TOPIC command to server in silcd/command.c.
3144 * Added two new notify types into lib/silccore/silcnotify.h:
3145 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3146 notify nickname change and topic setting/change on a channel.
3148 * API change of command_reply operation in client library. The
3149 application gets now the status type received from server as well.
3151 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3153 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3155 * Cras fixed and optimized the packet handling even further and
3156 it should work now. Minor change to the prototype of function
3157 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3159 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3161 * Added new function into lib/silcutil/silcschedule.[ch]:
3162 silc_schedule_with_fd to select() a specified fd. The function
3163 returns after timeout expires or data arrives or goes. The
3164 function is used by packet routines to wait that all data is
3165 received from network.
3167 * Fixed data reading from network in lib/silccore/silcpacket.c.
3168 The code now assures that all data is read from the fd and then
3169 continues packet processing. This was a bug fix since the code
3170 used to drop some data in some circumstances.
3172 * Added new function into lib/silcclient/client.[ch]:
3173 silc_client_start_key_exchange to start key exchange after
3174 connection has been established to server. The code internally
3175 now uses this funtion but its main purpose was to provide it
3176 for applications that perform their own connecting. After
3177 application has created a connection it merely calls this
3178 function to start the key exchange between client and server.
3179 The library takes care of everything else after that.
3181 Updated also lib/silcclient/README to explain the usage of
3184 * Do not send to application information that connection has
3185 been established. Application gets notified it by connect
3188 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3190 * Applied cras's patch to add silc_schedule_one function. The
3191 function runs scheduler once and returns.
3193 * Fixed the scheduler after cras messed it up. The timeout
3194 handling works now as it's supposed to work.
3196 * Added into lib/silccore/ silcnotify.h to include notify
3197 message types support. Changed silc_server_send_notify*
3198 functions, in server.[ch], to support those new notify types.
3199 Added the support for the notify types into client library,
3200 as well. Added new notify client operation into ops.h in
3203 * Changed silc_server_packet_send_to_channel to send normal
3204 packets instead of just channel message packets. The function
3205 is now used to send the notify packets to channels. It is not
3206 used to send channel message packets anymore, as server never
3209 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3210 va_arg()s as it seems to require it nowadays. I guess, if SILC
3211 is compiled with older va_arg() the new code should work anyway.
3213 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3215 * Splitted core library. Core library (lib/silccore) includes
3216 now only SILC protocol specific core (and common) components.
3217 Created new utility library (lib/silcutil) that includes more
3218 generic purpose stuff. The stuff for util library was taken
3219 from the old core library. This was minor and easy split.
3221 * Created SILC Client Library (lib/silcclient) that includes
3222 implementation of the SILC client without user interface. This
3223 was major move from silc/ directory. The code has been changed
3224 so that it is transparent towards the user interface. The
3225 silc/ directory includes now the same user interface as before
3226 and it uses the new client library. Read lib/silcclient/README.
3227 Basicly, the client library performs everything else related
3228 to SILC except user interface handling. Also, configuration
3229 files are considered to be part of user interface and library
3230 does not handle them.
3232 This change also changed a lot of structures, function naming etc.
3233 Most important change was that SilcClientWindow object was
3234 renamed to SilcClientConnection in the client library. Created
3235 also new file lib/silcclient/ops.h. Also added new files
3236 silc/local_command.[ch] and silc/client_ops.[ch].
3238 All these changes were made to make it easier for user interface
3239 designers to create what ever user interface for the SILC client
3242 It is also expected that the server will be moved to lib
3243 directory as well and SILC Server Library will be created;
3244 sometimes in the future.
3246 * Removed Local commands from lib/silccore/silccommand.h as
3247 they are application specific and new client library does not
3248 handle any of those anymore.
3250 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3251 old client implementation in silc/.
3253 * Added support for callback functions in SILC_LOG_* macros.
3254 Application can now set its own callbacks that will be called
3255 instead of using the default functions that will always print
3256 the debug messages to stderr (or stdout). Also, debugging can
3257 now be disabled by setting silc_debug to FALSE and re-enabled by
3258 setting it to TRUE. Note, that logging will still work even
3259 if debugging is disabled.
3261 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3262 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3263 silc_log_reset_debug_callbacks.
3265 * To enable debugging in silc client one must give now -d
3266 option on command line.
3268 * Changed silc_schedule_init to automatically allocate task queues
3269 if they are not allocated before calling it.
3271 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3273 * Added GMP 3.1 into math library.
3275 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3277 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3278 a channel in SILC network. The packet is used by servers and
3279 routers to notify other routers that user has left a channel.
3280 This little feature was missing until now. Added the feature
3281 to protocol specification as well.
3283 Added functions: silc_server_send_remove_channel_user and
3284 silc_server_remove_channel_user into server.[ch].
3286 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3287 lib/silccore/silcpacket.h. However, they are not implemented
3290 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Fixed joining to a channel and sending channel messages
3293 between server and router. The channel message sending should
3294 now work inside a cell.
3296 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3298 * Fixed the private message sending between server and router.
3299 The private message sending should now work inside a cell.
3301 * Added silc_server_replace_id into server.[ch] to replace
3302 existing ID in the SILC network.
3304 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3305 and silc_idlist_replace_server_id into idlist.[ch] in server.
3307 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * Fixed the server to server connections. Server can again now
3310 connect to router. Router to router connections probably does
3313 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3315 * Added dynamic protocol registering support. Now protocols can
3316 registered and unregistered on the fly. Patch by cras.
3318 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3320 * Added lib/contrib directory to hold routines that some platforms
3321 don't have but are needed by SILC.
3323 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3324 into lin/contrib to provide getopt() and getopt_long() for
3325 those who don't have it.
3327 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3329 * Added AWAY command to client. When away message is set and
3330 client receives a private message packet the client automatically
3331 replies to the sender with the away message.
3333 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3334 bug seemed to be the cause of recent problems when compiling
3337 * Added version detection support to SKE protocol specification
3338 and added the new changes to the SKE implementation as well.
3339 There were other minor changes in the SKE protocol as well.
3341 Many changes in lib/silcske/silcske.[ch] and in
3342 lib/silcske/payload.[ch].
3344 * Added ^U functionality, clear input line. Patch from cras.
3346 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3348 * Mainly small bugfixes on core library. Fixed some debugging
3349 logging and buffer overflow in silclog.c.
3351 * Updated config.sub and config.guess on the distribution tree.
3353 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3355 * Added command lagging support in server. Client may execute
3356 commands now only once in two seconds.
3358 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3360 * Optimized packet reception. MAC computation and checking is now
3361 also more optimized. A lot previously duplicated code is now
3362 used as generic by both client and server.
3364 * Fixed key pair generation in clientutil.c
3366 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3368 * Added into lib/silccore/silcbufutil.[ch] new function;
3369 silc_buffer_realloc.
3371 * Moved generic packet sending/encryption functions to
3372 lib/silccore/silcpacket.[ch] from client and server. Some
3373 rewriting of the functions.
3375 * Moved all generic packet reception/decryption functions to
3376 lib/silccore/silcpacket.[ch] from client and server. The
3377 packet processing is now much cleaner in both client and server.
3378 These were major changes in both client and server.
3380 * Created many common functions in server to do packet sending.
3381 Previously code were duplicated a lot, this has been removed
3384 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3386 * Rewrote major parts of the ID cache system. Don't know
3387 whether it is better now or not but at least the API is more
3390 * Major rewrite on ID cache stuff on client because of the ID
3391 cache API changes. Added idlist.c to client.
3393 * Also major rewrite on ID cache stuff on server as well.
3394 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3395 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3396 in hand, instead they are all put into the ID cache system now.
3397 All server_idlist_* routines uses ID cache now instead of
3398 traversing its own lists (those lists does not exist anymore).
3399 SilcIDList though still exists. Also, SilcXXXEntry's are
3402 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3404 * Finally made the SKE implementation compliant to the protocol
3405 specification. All mp integers are now binary encoded as
3406 opposed being HEX encoded.
3408 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3411 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3412 functions: silc_[encode/decode]_pem. Also added function
3413 silc_encode_pem_file to PEM encode with newlines ('\n') for
3416 * SILC public keys are now encoded either PEM or binary. Same
3417 option is for private keys as well. By default private keys
3418 are binary encoded and public keys PEM encoded. Silly HEX
3419 encoding were removed.
3421 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3422 function to create fingerprints.
3424 * Fixed a bug in SHA1; does not change the original data anymore.
3426 * Partly implemented INFO command on client and server side.
3427 Fixed CLEAR command. Changes to SERVER command; show current
3428 server(s) when giving command without arguments. Added
3429 VERSION command to client.
3431 * Added check to server that unregistered connections cannot
3432 execute commands (unless it is specificly allowed).
3434 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3436 * Fixed screen refresh.
3438 * Fixed channel joining bug from client. On some circumstances
3439 client tried to join to a channel it had already joined.
3441 * Added public key verification process into client's protocol.c.
3442 The client now verifies the public key from user and saves
3443 it into ~./silc/serverkeys/ directory.
3445 Added into: clientutil.[ch]: silc_client_verify_server_key.
3447 * Changed SKE protocol's silc_ske_initiator_finish function
3448 to accept callback function that verifies the received public
3449 key. Removed old silc_ske_verify_public_key function.
3451 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3453 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3454 silc_pkcs_private_key[_data]_set.
3456 * Made the password and public authentication more cleaner in
3457 server's protocol.c.
3459 * Removed historic and obsolete protocol `channel_auth' from
3460 both client and server.
3462 * Removed wrong way of sending command status messages from
3463 server to client in server's command.c. The old way violated
3464 protocol specification.
3466 Changes to silccore/silccommand.[ch]: removed
3467 silc_command_encode_status_payload -> not needed anymore,
3468 changed silc_command_encode_payload_va to accept extra
3469 argument on variable argument list. The argument type must
3470 now be provided to the function. Also, added new function:
3471 silc_command_encode_reply_payload_va which is same as
3472 normal command_encode_payload_va except command status type
3473 is provided as extra argument.
3475 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3477 * Added ~./silc directory handling. The directory includes the
3478 public and private keys for the client.
3480 Added silc_client_check_silc_dir, silc_client_create_identifier
3481 and silc_client_load_keys.
3483 * Implemented SILC protocol compliant public key. Added public
3484 and private key saving to and loading from files.
3486 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3487 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3488 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3489 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3490 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3492 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3493 silc_pkcs_load_[public/private]_key.
3495 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3497 * Added silc_server_get_route (route.[ch]) to get connection
3498 data for the fastest route for given ID.
3500 * Implemented INVITE command on client and server. The command
3501 were re-defined in the SILC Protocol Specification and the
3502 implementation now complies with the specification.
3504 * Implemented PING command on client and server.
3506 * Implemented NAMES command on client and server. The server side
3507 supports currently only normal server not router server yet.
3508 Some changes to NAMES definition in SILC protocol specification.
3510 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3512 * Implemented LEAVE command on client and server.
3514 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3515 again. This change was made to the protocol as well. Server
3516 should not violate the protocol specification anymore.
3518 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3520 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3521 was tested. SOCKS4 was not but should work anyway.
