3 * Compiled the SILC under cygwin. Compiled and tested briefly
4 without problems. More tests needed. The SIMs didn't compile
7 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
9 * Fixed possible crash in silc_get_username in the
10 lib/silcutil/silcutil.c.
12 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
14 * Fixed a va_arg in silc/client_ops.c.
16 * Oops, RC5 routines were named AES and caused some problems
17 when not using SIM's. Affected file lib/silccrypt/rc5.c.
19 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
21 * Added new SilcIDIP structure into the lib/silccore/id.h and
22 replaced the old `ip' fields from all SILC ID's to that type.
23 This is a step towards IPv6 support.
25 The silc_id_get_len takes now the ID as an extra argument.
26 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
27 both IPv4 and IPv6 based ID's.
29 The affected files are lib/silccore/id.[ch] and other files
30 around the tree using these routines.
32 * Removed the ID length arguments in server from various
33 silc_server_send_notify_* routines -> they are not needed
36 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
38 * Fixed memory leak in silc_encode_pem_file in the file
39 lib/silcutil/silcutil.c.
41 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
43 * Check minor version as well in the SKE. Affected files are
44 silcd/protocol.c and lib/silcclient/protocol.c.
46 * Added --identifier option to the server so that an identifier
47 can be when creating the public key for the server. Affected
48 file is silcd/silcd.c.
50 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
51 lib/silccrypt/silcpkcs.c.
53 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
55 * Register default ciphers and stuff when using -C option with
56 the server. Affected file sildc/silcd.c.
58 * Put back the servers public key filename format, it is better
59 than the new one. For now, the client keys are saved with the
60 new filename format. The affected file silc/client_ops.c.
62 * Implemented the Cipher API for the rest of the ciphers that
63 did not implement it or implemented it the wrong way.
65 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
67 * Register default ciphers and stuff when using the -S option
68 in the client. Affected file silc/silc.c. Same also when
69 creating new key pair with -C option.
71 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
73 * Fixed the silc_verify_public_key client operation function to
74 save the public keys differently. The fingerprint is now
75 used as filename and not the hostname. This way also the
76 client keys are saved uniquely and not with hostnames. The
77 affected file is silc/client_ops.c.
79 * Trimmed the silc_hash_fingerprint function to remove extra
80 whitespaces from the end of the fingerprint. The affected
81 file is lib/silccrypt/silchash.c.
85 * Added silc_cipher_register_default function to register all
86 default ciphers. It can be used when configuration files
87 does not exist and the application does not want any specific
88 ciphers in any specific order.
90 The SilcDList is now used as silc_cipher_list dynamically
91 allocated cipher list. Removed the static list all together
92 and now all ciphers must be allocated to the dynamic list.
93 The silc_cipher_alloc routine was changed to check only the
96 All silc_cipher_* routines that used to return int returns
99 The affected files lib/silccrypt/silccrypt.[ch].
101 * The same thing was done to silc_hash_* as for silc_cipher_*
102 routines. Affected files lib/silccrypt/silchash.[ch].
104 * The same thing was done to silc_pkcs_* as for silc_cipher_*
105 routines. Affected files lib/silccrypt/silcpkcs.[ch].
106 Added also silc_pkcs_[un]register[_default] functions.
107 Removed the data_context from the PKCS API.
109 * Added silc_hmac_register_default function to register default
110 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
111 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
112 to unregister all hmacs at once.
114 * Register the default ciphers, hash functions, PKCSs and HMACs
115 if client's configuration file does not exist. The affected
118 * The client did not load the hash functions from the SIM
119 modules at all. Added support for this. Affected file is
122 * When decoding public key with silc_pkcs_public_key_decode, check
123 the supported algorithm only if PKCS are registered. Affected
124 file lib/silccrypt/silcpkcs.c. The same was done with the
125 silc_pkcs_private_key_decode.
127 * Fixed the SILC List routines to keep the list always in order.
128 It used to change the list's order when traversing the list but
129 not it preserves the order. Affected file lib/trq/silclist.h.
131 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
133 * Added the client library to use the SilcSocketConnection's
134 reference counter (by silc_socket_dup) to prevent the bug that
135 the socket object may be freed underneath async operation.
137 * The name resolv library checking fixes in the configure.in.pre.
140 * Created new version of the protocol drafts for future
141 development. The -03 drafts are the ones that will be changed
142 in the trunk now and the -02 will remain as they are.
144 * Send list of CUMODE notifys to the router when announcing
145 the channel users to the router. Affected file silcd/server.c.
146 If the router receiving channel founder CUMODE for a channel
147 that already has channel founder it will send CUMODE notify
148 to the sender to remove the channel founder rights from the
149 announced client. Affected file silcd/packet_receive.c.
151 * The CUMODE notify may now use Server ID as well as the entity
152 who changes the mode. Updated protocool specs.
154 * Updated INSTALL and README files.
156 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
158 * New web pages in the http://silc.pspt.fi. The pages was
163 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
165 * Implemented the [DenyConnectin] config section in the server.
166 Added silc_server_config_denied_conn to check whether incoming
167 connection is denied. Affected file silcd/serverconfig.[ch].
169 * Do not check the ports when checking the incoming configuration
170 data if the port is 0, meaning any. Affected file is
171 silcd/serverconfig.c.
173 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
175 * Fixed buffer overflow in silc_string_compare in the file
176 lib/silcutil/silcutil.c.
178 * Fixed double free in silc_server_command_leave in the file
181 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
183 * Fixed the version checking in the server. Affected file is
186 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
188 * Fixed the configuration data fetching when accepting new
189 connections in the server. Affected file silcd/server.c.
191 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
193 * Added `sender_entry' argument to the function
194 silc_server_packet_relay_to_channel so that we can check
195 whether some destination actually belongs to the same route
196 the sender belongs (ie, we must not resend the packet to the
197 sender). Affected file silcd/packet_send.[ch].
199 * Added `servername' field to the SilcClientEntry in the server
200 to hold the name of the server where client is from. Affected
201 file is silcd/idlist.h.
203 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
205 * Moved the channel message encrypting in the router betwen
206 router connections from silc_server_channel_message to the
207 silc_server_packet_relay_to_channel since we want to check
208 whether we have anybody channel before encrypting anything.
209 Affected files silcd/packet_[receive/send].c.
211 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
213 * Fixed the [AdminConnection] server config section to support
214 multiple entries. Affected file silcd/serverconfig.c.
216 * Added support into the server to check the validity of the
217 incoming connection before executing any KE or authentication
220 * The connection configuration is now saved to the KE and
221 connection auth protocol contexts and not fetched anymore in
222 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
224 * The local hosts listenning address and port is also resolved
225 now when starting the server. We want to have the socket object
226 to include the real address and port for the listener. Added
227 new function silc_net_check_local_by_sock into the files
228 lib/silcutil/silcnet.[ch].
230 * Fixed a broadcast bug in server -> do not broadcast if we
233 * Fixed a routing bug. Do not route broadcast packets ever.
234 Broadcast packets must be processed always and not routed since
235 they may be destined to some other host than yourself and thus
236 would get routed without no good reason. Affected file is
239 * Added function silc_server_config_is_primary_route to check
240 whether primary router connection has been configured (a router
241 configuration that we are initiating). If there is not, we
242 will assume that there is only two routers in the SILC network
243 and we will use the incoming router connection as our primary
244 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
246 * Changed the order of the broadcasting. Broadcast _after_ the
247 packet has been processed not before. Affected file is
250 * Fixed a [ClientConnection] parsing bug. The port was never
251 parsed correctly thus resulting to port 0. Affected file
252 silcd/serverconfig.c.
254 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
255 argument and did not set the broadcast packet flag. Affected
256 file silcd/packet_send.c. Fixed same bug in the function
257 silc_server_send_notify as well.
259 * If we receive NEW_ID packet for our own ID in the server, ignore
262 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
266 * Removed the nickname from the Private Message Payload.
267 Updated the code and the protocol specs.
269 * Updated protocol specs for submitting to the IETF.
271 * Tweaked the Random Number Generator a bit. Affected file
272 lib/silccrypt/silcrng.c. Exported a new function
273 silc_rng_[global]_add_noise which can be used to add more
276 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
278 * Do not parse packets with different timeout when protocol
279 is active -> may cause problem with rekey. Affected file
282 * When server receives signoff notify it must not create
283 new channel key if the client is on any channels since the
284 sender of the signoff notify will create it.
286 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
288 * Added printing of error messages during SKE protocol from the
289 failure packet sent by server during SKE. Affected file
292 * Removed the client's failure_callback handling with timeout
293 and handle it immediately when received.
295 * The SKE library returned wrong type in SUCCESS and FAILURE
296 packets. They must be 32 bit MSB not 16 bit MSB.
298 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
300 * Ok, rewrote the logic of the re-key and now it seems to work.
301 I tested it on high traffic with frequent re-keys without
302 problems. Added hmac_receive (and renamed hmac to hmac_send)
303 in SilcClientConnection in lib/silcclient/client.h and
304 in SilcIDListData in silcd/idlist.h. Also, removed the
305 SilcPacketParserContext's cipher and hmac fields as they are
306 not needed anymore and actually caused some problems when
307 the ciphers and hmac's changed underneath the packet parser.
309 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
311 * If re-key protocol is active then process the incoming packets
312 synchronously since we must assure that icoming packets encrypted
313 with the old key is processed before the new keys is set to
314 use. This is true other packets than for REKEY packets.
315 Affected file silcd/server.c. The same was done to client library
316 as well, affected file lib/silcclient/client.c.
318 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
320 * Fixed bug in client and server to accept the force send if
321 the packet is send from silc_[server/client]_packet_process
322 function. Otherwise the packets are never delivered, oops.
324 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
326 * Disable force sending of packets when REKEY protocol is active.
327 We must assure that no packet is sent directly when rekey is
328 performed. All packets must be sent through packet queue.
329 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
330 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
331 function is silc_[server/client]_packet_send_real to check
334 * Replaced the SIM paths from example config files to
335 /usr/local/modules. Also, make install creates now
336 /usr/local/silc/logs directory to hold all the SILC server
339 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
341 * Made the configure.in.pre work on Solaris. Patch by salo.
343 * Made all ciphers compatible with non-x86 machines. Defined
344 CBC mode macros into lib/silccrypt/ciphers_def.h.
346 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
348 * Fixed the make install.
350 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
352 * When MAC computation fails the silc_packet_decrypt returned 0
353 even though it was supposed to return -1. Fixed this. The
354 affected file is lib/silccore/silcpacket.c.
356 * Do not replace the config files in /etc/silc (in make install)
357 if they already exist. Affected file ./Makefile.am.
359 * Do not send re-key packets immediately but through packet queue.
360 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
362 * Changed silc_net_check_host_by_sock to return FALSE if the
363 IP/DNS could not be resolved. Though, it returns the IP address
364 now even if it could not resolve it (but returns also FALSE).
365 Affected file lib/silcutil/silcnet.[ch].
367 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
369 * Added silc_pkcs_decode_identifier to decode the public key's
370 identifier. Affected file lib/silccrypt/silpkcs.[ch].
371 Added also silc_pkcs_free_identifier. Added also new context
372 SilcPublicKeyIdentifier.
374 * Added -S option to the silc client. It is used to dump the
375 contents of the specified public key file.
377 * Changed the PKCS api to return the public key length when
378 setting the public key.
380 * Fixed a fatal bug in the public and private key file loading.
381 Affected file lib/silccrypt/silcpkcs.c.
383 * Execute the packet parsing for client with zero (0) timeout
384 if the protocol is active. Affected file silcd/server.c.
386 Sun Apr 8 19:30:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
388 * Made the key generation options to the silcd program. Added
389 -C option, equivalent to client's option.
391 * Added new [ServerKeys] config section to the server. It
392 configures the server's public and private key.
394 * Defined generic Public Key Payload into the protocol
395 specification to send specific type of public keys and
398 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
399 public key or certificate.
401 * Implemented the GETKEY command to the server and to the
402 client library and on user interface.
404 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
406 * Made preliminary `make install' work.
408 Thu Apr 5 17:42:30 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
410 * Added SilcServerRekey context into silcd/idlist.h.
412 * Added the PFS support as defined in the specification to the
413 SKE protocol. Affected files lib/silcske/*.c.
415 * Added `ske_group' field to the SilcServerRekey context to hold
416 the number of the SKE group that is used with PFS in re-key.
417 Affected file silcd/idlist.h.
419 * Added PFS re-key support to the server. Affected file is
422 * Added silc_protocol_cancel to cancel execution of the next
423 state of the protocol. Affected file is
424 lib/silccore/silcprotocol.[ch].
426 * Added the re-key support with and without PFS to the client
427 library. Re-key is performed once in an hour, by default.
429 Added new protocol type SILC_PROTOCOL_CLIENT_REKEY.
430 Added silc_client_rekey_callback and silc_client_rekey_final.
431 Affected files are lib/silcclient/protocol.[ch] and
432 lib/silcclient/client.[ch].
434 * Removed the `hmac_key' and `hmac_key_len' fields from the
435 SilcClientConnection structure; not needed. Affected file is
436 lib/silcclient/client.h.
440 Wed Apr 4 16:32:31 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
442 * Do not ask whether user wants to use the negotiated private key
443 for private messages, just use it. Affected file is
444 silc/local_command.c.
446 * Added `send_enc_key' and `enc_key_len' fields to the
447 SilcIDListData structure since they are needed in the re-key
448 phase. Affected file is silcd/idlist.[ch].
450 * Implemented the simple re-key protocol into the server.
451 Affected files silcd/server.c and silcd/protocol.[ch]. The
452 re-key will be performed once in an hour, by default.
454 Added new protocol type SILC_PROTOCOL_SERVER_REKEY.
455 Added silc_server_rekey, silc_server_rekey_callback and
456 silc_server_rekey_final.
458 * Removed Tunneled flag from the protocol. Updated the code
459 and the specifications.
461 * Adde `pfs' field to the SilcIDListData to indicate whether
462 the PFS is to be performed in the re-key. Affected file is
465 Tue Apr 3 21:52:42 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
467 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
468 int64 of at least the xintXX size. If void * is less that 4
469 bytes uint32 * will be used. Defined bool as boolean.
471 * Changed _ALL_ unsigned long and unsigned int to uint32,
472 unsgined short to uint16 in the source tree.
474 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do
475 not handle clients that has entry->data.registered == FALSE.
476 They are not in the network anymore. Affected file is
479 Tue Apr 3 16:39:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
481 * Implemented the sending of the SERVER_SIGNOFF notify in the
482 server. Affected file is silcd/server.c.
484 * Added silc_server_send_notify_args into silcd/packet_send.[ch].
485 Added also silc_notify_payload_encode_args into the
486 lib/silccore/silcnotify.[ch].
488 * Implemented ther SERVER_SIGNOFF notify handling in the server.
489 Affected file silcd/packet_receive.c.
491 * Implemented the SERVER_SIGNOFF notify handling in the client
492 library. Affected file lib/silcclient/client_notify.c. Also,
493 implemnted the printing of the SERVER_SIGNOFF info to the
494 application. Affected file silc/client_ops.c.
496 * The silc_idlist_del_server now returns TRUE or FALSE to indicate
497 if the deleting was successful. Affected file silcd/idlist.[ch].
499 * Added support for public key authentication in the connection
500 authentication protocol in the client library. Affected file
501 lib/silcclient/protocol.c.
503 * Changed the server's silc_idlist_get_clients_by_* interface
504 to support already allocated array so that new entries may be
505 added to pre-allocated array. Affected file silcd/idlist.[ch].
506 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
509 * All command reply functions in the server now calls the
510 pending command callback even if error occured. This way the
511 error will be delivered to the client as well. Affected files
512 silcd/command.c and silcd/command_reply.c.
514 * Fixed INFO command to return local server's info if no server
515 was provided. Affected file lib/silcclient/command.c.
517 * Removed RESTART command for good. Updated the code and the
520 * Rewrote parts of the task system. It is a bit simpler now.
521 Removed unsued task priorities. The affected files are
522 lib/silcutil/silctask.[ch].
524 Mon Apr 2 20:02:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
526 * Moved the USERS printing from the library to the application.
527 Affected files lib/silcclient/command.c and silc/client_ops.c.
529 Mon Apr 2 13:13:23 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
533 * Added channel key re-key support. The re-key is perfomed
534 only by the router and is done once in an hour. Added `rekey'
535 field to the SilcChannelEntry in the server. Affected files
536 silcd/server.c and silcd/idlist.h.
538 * Added silc_task_unregister_by_context into the file
539 lib/silcutil/silctask.[ch].
541 Sun Apr 1 19:49:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
543 * Added SILC_UMODE_GONE mode to indicate when the client is not
544 present in the SILC network. Added also support to the local
545 command AWAY that will set this mode. Added support of showing
546 "xxx is gone" in WHOIS command. The USERS command shows the
549 * Fixed setting server and router operator privileges in the
550 server's UMODE command. Affected file silcd/command.c.
552 * Merged the SKE KE1 and KE2 payloads into one payload. The
553 new KE payload is equivalent to the old KE2 payload.
555 Cleaned up the SKE Start Payload parsing. It now uses the
556 simple buffer unformatting to do the parsing. A lot faster
559 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
560 to the SKE that is used to indicate whether both of the SKE
561 parties should perform authentication. By default only the
562 responder performs authentication. By setting this flag also
563 the initiator must do authentication. By default it is unset
564 since in normal SKE case, client to server connection, only
565 the responder should do authentication. When doing SKE between
566 two clients both should perform authentication. Updated the
567 code and the protocol specs.
569 * A little fix to IDENTIFY command in the server. Search the
570 client first by hash not nickname. Affected file is
573 * Fixed the silc_client_close_connection to support closing
574 the client to client connections wihtout deleting too much
575 data. Affected file lib/silcclient/client.c.
577 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
578 are received if protocol used to be active but is not anymore
579 the application would crash due to NULL pointer dereference.
580 Affected files silcd/server.c and lib/silcclient/client.c.
582 * Added `hash' field to the SilcClientConnection to include
583 the hash function negotiated in the SKE protocol.
585 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
586 to set the channel founder authentication data. A client can
587 claim the founder rights later by providing the authentication
588 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
589 This way the channel founder can regain the channel founder
590 privileges even it is left the channel. This works only on
591 local server and the client must be connected to the same
592 server to be able to regain the founder rights. Updated the
593 protocol specs accordingly.
595 Added support to the CMODE command in the client to set the
596 founder auth data. Read the README to see how to set it.
598 Added support to the CUMODE command to claim the founder
599 rights. Read the README to see how to do it.
601 Added support for the founder authentication to the Channel
602 Entry in the server. Affected file silcd/idlist.h.
604 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
605 server's CMODE command. Affected file silcd/command.c.
607 * Added the following new functions into lib/silccore/silcauth.[ch]:
608 silc_auth_get_method and silc_auth_get_data.
610 * The server now saves the remote hosts public key to the
611 SilcIDListData pointer. Affected file silcd/protocol.c.
613 * The normal server now does not remove the channel entry from
614 the cache if the founder authentication data is set. It used
615 to remove it if the founder was the last one on the channel on
616 the server and left the channel. The auth data is saved and
617 if the channel is re-joined later the old entry is used with
618 the old auth data. Affected files silcd/command_reply.c and
621 * Removed the `pkcs' field from the SilcIDListData structure
622 in the server; it is not used. Affected file silcd/idlist.h.
624 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
626 * Fixed packet processing on slow links. Partial packets were
627 never re-processed because the incoming data buffer was cleared
628 by the application. Application must not directly clear the
629 sock->inbuf, the packet processing routines handle it. Fixed
630 this in client library and in server.
632 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
634 * Fixed the WHOIS and IDENTIFY send reply function to really
635 check whether to send list or just one entry. Affected file
638 * Cleaned up the LEAVE command's channel key distribution. The
639 affected file silcd/command.c.
641 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
642 can enforce the channel mode as well. In that case the ID
643 includes the ID of the server. The code now enforces the
644 mode change if the router have different mode than the server.
646 * The notify client operation with CMODE_CHANGE notify can now
647 return NULL client_entry pointer if the CMODE was not changed
648 by client. Application must check for this.
650 * Added <Server ID> argument to INFO command to support server
651 info fetching by Server ID.
653 * Added silc_server_announce_get_channel_users to get assembled
654 packets of channel users of the specified channel. Affected
655 file silcd/server.[ch].
657 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
658 was freed underneath the ID Cache.
660 * Re-announce clients when the server received CHANNEL_CHANGE
661 notify from the router. Affected file silcd/packet_send.c.
663 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
665 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
666 crashed since it did not handle the fact that there is no cipher
667 called "3" and didn't check the error condition. Now fixed.
669 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
670 flag. It can be used to send message requests.
672 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
674 * Implemented the RESTART command in the client.
676 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
677 notice type messages. Added notice printing to the user
680 * The channel keys are not re-generated if the channel's mode
681 is PRIVKEY, ie private key on the channel exists. Affected
682 files silcd/server.c and silcd/command.c.
684 * Fixed a little bug in channel message delivery when channel
685 private keys are set in the server. Affected file is
688 * Changed the setting on channel->on_channel = TRUE from the
689 silc_client_save_channel_key to the JOIN command reply. The
690 key payload is not received if the private channel key is set.
691 Affected file lib/silcclient/command_reply.c and the
692 lib/silcclient/client_channel.c.
694 * When the CMODE_CHANGE notify is sent and the channel private
695 key mode is removed the channel key must be re-generated in
696 other cells as well. Added this support for the router in the
697 silcd/packet_receive.c.
699 * Added new local command NOTICE to send notice message on
700 channel. Affected file silc/local_command.[ch].
702 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
704 * Added new local command ME to the client. It is used to send
705 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
706 some action. Affected file silc/local_command.[ch].
708 * Changed channel_message and private_message client operations
709 to deliver the message flags to the application. Added also
710 the `flags' arguments to the silc_client_send_channel_message
711 and silc_client_send_private_message functions. Affected file
714 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
716 * Redefined the Private Message Payload to support private message
717 keys and to support the new private message flags. Updated
718 the protocol specs. Flags makes it possible to have for example
721 * Added new type SilcPrivateMessagePayload and defined an API
722 for it in the lib/silcclient/silcprivate.[ch].
724 * Tested private message private keys successfully. Tested the
725 private message key set, unset and list commands with the new
728 * Redefined the Channel Message Payload to include the channel
729 message flags (equal with private message flags) to support
730 for example CTCP style messages.
732 * Defined some of the message (for channel and private message)
733 flags. Updated the protocol specs and added the flags to the
734 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
736 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
738 * Added SilcKeyAgreementStatus type to the key agreement routines
739 to indicate the current status and error if one occured.
740 The status types are defined in the lib/silcclient/silcapi.h.
742 * Added new local command KEY that is used to set and unset private
743 keys for channels, set and unset private keys for private messages
744 with remote clients and to send key agreement requests and
745 negotiate the key agreement protocol with remote client. The
746 key agreement is supported only to negotiate private message keys,
747 it currently cannot be used to negotiate private keys for channels,
748 as it is not convenient for that purpose.
750 * Fixed a minor pending callback setting bug in the function
751 silc_client_get_client_by_id_resolve, now the function works.
752 Affected file lib/silcclient/idlist.c.
754 * Added function silc_net_get_local_port to get local bound
755 port by socket. Added to lib/silcutil/silcnet.[ch].
757 * Added `sockets' and `sockets_count' fields to the SilcClient
758 object. They hold the sockets of the listenning sockets in
759 the client. Listenning sockets may be for example the key
760 agreement server. Affected file lib/silcclient/client.[ch].
761 Added functions the silc_client_add_socket and the
762 silc_client_del_socket. They are exported to the application
765 * Added ~./silc/clientkeys to support other client's public keys.
767 * Renamed verify_server_key client operation to verify_public_key
768 and added one argument to indicate the type of the connection
769 (server, client etc.).
771 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
773 * Added silc_server_connection_auth_request to handle the
774 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
775 silcd/packet_receive.[ch].
777 * Added silc_server_send_connection_auth_request into the
778 silcd/packet_send.c to send the connection auth request packet.
780 * Cleaned up the silcd/protocol.c a bit and fixed some memory
783 * Fixed the public key authentication in responder side in the
784 server. The `auth_data' pointer includes the SilcPublicKey
785 not the path to the public key. Affected file silcd/protocol.c.
787 * Implemented the public key authentication in the initiator side
788 in the server. Affected file silcd/protocol.c.
790 * Removed the [RedirectClient] config section from the server
791 configuration. Is not needed and I don't want to implement it.
793 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
795 * Cleaned up the CMODE command in the server. It now works
796 correctly and supports all the modes defined in the protocol.
797 Affected file is silcd/command.c.
799 * Added `hmac_name' field to the SilcChannelEntry in the server
800 to hold the default HMAC of the channel. It can be set when
801 creating the channel (with JOIN command). Affected files
804 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
805 type to indicate the change of the current cipher and hmac
806 on the channel. Client can safely ignore the <cipher> argument
807 (if it chooses to do so) since the CHANNEL_KEY packet will
808 force the channel key change anyway. The <hmac> argument is
809 important since the client is responsible of setting the new
810 HMAC and the hmac key into use.
812 * Fixed the CMODE command in the client library as well.
814 * Tested CMODE command in router environment successfully.
816 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
818 * Show the version of the remote client (or server) when connecting
819 to the server. It is logged to the log file. Affected file
822 * Fixed the KILLED notify handling in the client library. The
823 client must be removed from all channels when receiving the
826 Also, do not remove the client entry when giving the KILL
827 command but when the KILLED notify is received.
829 * Removed silc_idlist_find_client_by_nickname from the server.
830 Not needed anymore. Affected files silcd/idlist.[ch].
832 * Implemented the CHANNEL_CHANGE notify type handling to the
833 server. Affected file silcd/server.c.
837 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
839 * Added silc_server_send_notify_invite to send the INVITE
840 notify between routers.
842 * Implemented the INVITE command correctly to the server.
844 * Implemented the INVITE notify type handling in the server.
846 * Implemented the INVITE command to the client library and on the
849 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
851 * Added function silc_server_get_client_resolve to find the
852 client entry by ID from all ID lists and then resolve it
853 (using WHOIS) if it cannot be found. Affected file is
856 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
858 * Implemented the BAN command to the client library.
860 * The JOIN command in the server now checks the invite list
863 * Changed the silc_command_reply_payload_encode_va and the
864 silc_command_payload_encode_va to support that if argument is
865 NULL it ignores and checks the next argument. Affected file
866 lib/silccore/silccommand.c.
868 * Added silc_server_send_notify_ban to send the BAN notify
869 type between routers.
871 * Chaned the silc_notify_payload_encode to support that if
872 argument is NULL it ignores and checks the next argument.
873 Affected file lib/silccore/silcnotify.c.
875 * Tested ban lists in router environment successfully.
877 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
879 * Implemented BAN command to the server, in silcd/command.[ch].
881 * Removed the BAN and INVITE_LIST modes from the CMODE command
884 * Added function silc_string_match to regex match two strings.
885 Affected files lib/silcutil/silcutil.[ch].
887 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
889 * Redefined parts of the SilcChannelEntry in the server to support
890 the new ban and invite lists.
892 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
894 * Redefined the INVITE command. The same command can be used to
895 invite individuals to the channel but also to manage the invite
896 list of the channel (to add to and remove from the invite list).
897 Updated the protocol specs.
899 * Added new command SILC_COMMAND_BAN that can be used to manage
900 the ban list of the channel. Updated the protocol specs.
902 * Removed the channel modes: the SILC_CMODE_BAN and the
903 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
904 in the CMODE command. The equivalent features are now available
905 using INVITE and BAN commands. Updated the protocol specs.
907 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
908 in the network about change in the current ban list. The notify
909 type is not used by the client.
911 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
912 support the invite lists.
914 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
916 * Added new function silc_string_regexify that converts string
917 including wildcard characters into regex string that can
918 be used by the GNU regex library. Added into the file
919 lib/silcutil/silcutil.[ch].
921 Added silc_string_regex_combine to combine to regex strings
922 into one so that they can be used as one regex string by
923 the GNU regex library. Added into the file
924 lib/silcutil/silcutil.[ch].
926 Added silc_string_regex_match to match two strings. It returns
927 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
929 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
931 * Imported GNU regex to the soruce tree into lib/contrib.
932 Fixed some compiler warning from the regex.c.
934 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
936 * Fixed MOTD command in the server to work in router environment.
938 * Fixed the MOTD command in the client library to support
939 the server argument in the command.
941 * Added `nickname_len' argument to the silc_idlist_add_client
942 in the server, as the `nickname' argument may be binary data
945 * Added silc_idlist_get_channels to return all channels from
948 * Implemented LIST command to the server. Affected file is
951 * Implemented the LIST command to the client library and on the
954 * Added [<user count>] argument to the LIST command reply.
955 With private channels the user count is not shown.
957 * Updated TODO and README.
959 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
961 * The client entry's data.registered must be TRUE even with
962 global client entry on global client list. The data.registered
963 is used to check whether the client is anymore in the network,
964 for example with WHOWAS command so it must be valid.
966 * Fixed the WHOWAS command in the server. It now actually works
967 in router environment. Added function into silcd/command_reply.c
968 silc_server_command_reply_whowas_save.
970 * Added silc_idlist_purge function to the silcd/idlist.c
971 to periodically purge the ID Cache.
973 * Fixed INFO command in the server. It works now in router
974 environment. Added <server name> argument to the INFO command
975 reply. Updated the protocol specs.
977 * Fixed minor bug in silc_idcache_purge to not purge if the
978 expire value is zero.
980 * Fixed various bugs in WHOIS and IDENTIFY command handling as
981 they were buggy because of the WHOWAS information.
983 * Fixed local command MSG to handle the async resolving of
984 the remote client properly. It used to fail the first MSG.
985 Affected file silc/local_command.c.
987 * Added `data_len' field to SilcIDCache context.
989 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
991 * Update TODO. Todo in commands in the server.
993 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
995 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
996 used by routers as broadcast packet to inform other routers
997 about the changed user mode.
999 Implemented the notify handling in the server. Affected file is
1000 silcd/packet_receive.c. Added the function
1001 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1003 * Added new generic Channel Payload and deprecated the New Channel
1004 Payload. The New Channel Payload is now the generic Channel
1007 * Added new argument `mode' to the silc_server_send_new_channel
1008 as it is required in the Channel Payload now.
1010 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1011 and created a new and real SilChannelPayload to represent the
1012 new generic Channel Payload. Implemented the encode/decode
1013 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1015 * Added silc_server_get_client_channel_list to return the list
1016 of channels the client has joined for WHOIS command reply.
1017 Affected file silcd/server.[ch].
1019 * Implemented the channel list sending in the WHOIS command reply
1020 in server and in the client.
1022 Implemented the channel list displaying on the user interface
1023 as well. Affected file silc/client_ops.c.
1025 * Added silc_channel_payload_parse_list to parse list of Channel
1026 Payloads. It returns SilcDList list of SilcChannelPayloads.
1027 Client for example can use this function to parse the list of
1028 channels it receives in the WHOIS command reply. The caller
1029 must free the list by calling silc_channel_payload_list_free.
1030 Affected files lib/silccore/silcchannel.[ch].
1032 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1034 * Added one new argument <user mode> to the WHOIS command reply
1035 to return the mode of the user in SILC. Updated the protocol
1038 Implemented it to the server and client.
1040 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1042 * Fixed the mode printing on the user interface on joining.
1043 Affected file silc/client_ops.c.
1045 * Implemented the UMODE command and user modes in general to the
1046 client library and to the user interface.
1048 * Implemented the UMODE command to the server.
1050 * The server now sends UNKNOWN_COMMAND error status if client sends
1051 unknown command. Affected file silcd/command.c.
1053 * All server commands now handle the command identifier the right
1054 way when sending the command reply to the client. The client can
1055 use to identify the command replies with the identifier.
1057 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1059 * Added silc_server_get_client_route to resolve the route to
1060 the client indicated by the client ID. Affected file is
1063 * Added silc_server_relay_packet as general function to relay
1064 packet to arbitrary destination. This deprecates functions
1065 like _send_private_message_key, _relay_notify etc. Affected
1066 file is silcd/packet_send.[ch].
1068 Removed silc_server_send_key_agreement,
1069 silc_server_send_private_message_key and
1070 silc_server_packet_relay_notify functions from the file
1071 silcd/packet_send.[ch].
1075 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1076 server. Affected file silcd/packet_receive.[ch].
1078 * Implemented the KILL command to the client. Implemented the
1079 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1080 Affected files lib/silcclient/command[_reply].c and
1081 lib/silcclient/client_notify.c. Implemented the KILL notify
1082 printing in the user inteface.
1084 * Fixed a lot silc_parse_nick memory leaks from the client
1085 library in the file lib/silcclient/command.c.
1087 * Changed the silc_server_send_notify_on_channels's `sender'
1088 argument from SilcSocketConnection to SilcClientEntry to
1089 check the sender as entry and not as connection object and not
1090 to send to the client provided as argument. The affected file
1091 is silcd/packet_send.[ch].
1093 * The notify packets that are destined directly to the client used
1094 to not to be processed by the server. Now changed that and the
1095 server processes all notify packets. After relaying the packet
1096 to the client the notify packet is processed in the server.
1098 * The silc_server_free_client_data now checks whether there is
1099 pending outgoing traffic for the client and purges the data to
1100 the network before removing the client entry.
1102 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1105 an client is killed from the SILC Network. Updated the protocol
1108 Added new function silc_server_send_notify_killed to the
1109 silcd/packet_send.[ch].
1111 * Added function silc_server_packet_relay_notify to relay notify
1112 packets that are destined directly to a client. In this case
1113 the server does not process the notify packets but merely relays
1114 it to the client. Affected file silcd/packet_send.[ch].
1116 Added also silc_server_packet_process_relay_notify to check
1117 whereto relay the notify. Affected file is
1118 silcd/packet_receive.[ch].
1120 * Implemented the KILL command to the server.
1124 * Added the backup schema desgined last fall to the protocol
1125 specs for everyone to see. The specification is in the
1126 *-spec-xx.txt draft and the packet type definitions for the
1127 backup routers is in *-pp-xx.txt draft. Thusly, added also
1128 new packet type SILC_PACKET_CELL_ROUTERS.
1130 * A big security problem in the implementation discovered. The
1131 signoff of an client did not cause new channel key generation
1132 which it of course should've done. The channel keys must be
1133 always re-generated when client leaves (or signoffs) the channel.
1134 The silc_server_remove_from_channels funtion now handles
1135 the channel key re-generation.
1137 * Added `sender' argument to the silc_server_send_notify_on_channels
1138 to not to send the client provided as argument. Affected file
1139 silcd/packet_send.[ch].
1141 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1143 * Implemented OPER and SILCOPER commands into the server and
1146 * Added silc_auth_verify and silc_auth_verify_data to verify
1147 the authentication directly from the authentication payload.
1148 It supports verifying both passphrase and public key based
1149 authentication. Affected file lib/silccore/silcauth.[ch].
1151 * Added `hash' field to the SilcIDListData structure. It is the
1152 hash negotiated in the SKE protocol. Affected file is
1155 * Slight redesigning of the SilcAuthPayload handling routines.
1156 Do not send SilcPKCS but SilcPublicKey as argument.
1158 * Implemented the public key authentication support to the
1159 serverconfig. The public key is loaded from the provided path
1160 and saved as authentication data to void * pointer. Thus,
1161 changed the unsigned char *auth_data to void *auth_data;
1163 * Fixed SHUTDOWN command to send the reply before the server
1164 is shutdown. :) Affected file silcd/command.c.
1166 * Fixed fatal bug in CONNECT command. The hostname was invalid
1167 memory and server crashed. Affected file silcd/command.c.
1169 * Fixed fatal bug in CLOSE command. The server_entry became
1170 invalid but was referenced later in the command. Affected file
1173 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1175 * Fixed fatal bug in failure packet handling. Server ignored
1176 the failure and thus crashed when it came.
1180 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1183 that the command may be executed only once in (about) 2 seconds.
1184 The old SILC_CF_LAG flag is same but allows command bursts up
1185 to five before limiting.
1187 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1188 server code. Various commands now includes the CF_LAG_STRICT
1189 flag to disallow any kind of miss-use of the command.
1191 * Fixed the silc_buffer_unformat to not to allocate any data
1192 if the length of the data is zero. It used to allocate the
1193 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1195 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1197 * Changed the format of AdminConnection configuration section
1198 in the server. Added username of the admin to the format.
1199 Affected files silcd/serverconfig.[ch].
1201 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1202 to return admin configuration data by host, username and/or
1205 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1207 * Implemented WHOWAS command to the server. Added the functions:
1209 silc_server_command_whowas_parse,
1210 silc_server_command_whowas_send_reply,
1211 silc_server_command_whowas_from_client and
1212 silc_server_command_whowas_from_server
1214 * Added <Client ID> argument to the WHOWAS command reply. Updated
1215 the protocol specs accordingly.
1217 * Implemented WHOWAS command and command_reply to the client
1220 Implemented the WHOWAS printing on the user interface.
1222 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1224 * Added new argument to the WHOWAS command reply, the real name.
1225 It is an optional argument. Updated the protocol specs.
1227 * Added SilcIDCacheDestructor callback that is registered when
1228 the SilcIDCache is allocated. The callback is called when
1229 an cache entry in the ID Cache expires, or is purged from the
1230 cache. Added into lib/silccore/idcache.[ch].
1232 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1233 to destruct the client entries when the cache entry expires.
1234 Other ID Cache's in server and in the client library ignores
1237 * If the ID Cache entry's `expire' field is zero then the entry
1238 never expires. Added boolean `expire' argument to the
1239 silc_idcache_add function in the lib/silccore/idcache.[ch].
1240 If it is TRUE the default expiry value is used.
1242 * Added silc_server_free_client_data_timeout that is registered
1243 when client disconnects. By default for 5 minutes we preserve
1244 the client entry for history - for WHOWAS command.
1246 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1248 * Added support to the server to enforce that commands are not
1249 executed more than once in 2 seconds. If server receives
1250 commands from client more frequently, timeout is registered
1251 to process the commands. Affected file silcd/command.c.
1252 Added new function silc_server_command_process_timeout.
1254 * Changed NICK_NOTIFY handling in client library to check that
1255 if the client's nickname was changed, so there is no need to
1256 resolve anything from the server.
1258 * Removed error printing from the WHOIS and IDENTIFY commands.
1259 If error occurs then it is ignored silently in the client library.
1260 The application, however, may map the received error to
1261 human readable error string. The application currently maps
1262 the NO_SUCH_NICKNAME error to string.
1264 * Made the command status message public to the application. Moved
1265 them from lib/silcclient/command_reply.c to
1266 lib/silcclient/command_reply.h. The application can map the
1267 received command status to the string with the
1268 silc_client_command_status_message function.
1270 * Added check to the server to check that client's ID is same
1271 as the Source ID in the packet the client sent. They must
1274 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1276 * Added dist-bzip hook to the Makefile.am to make bzip2
1277 compressed distributions.
1279 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1281 * Server now enforces the maximum length for the nickname and
1282 the channel as protocol specification dictates. 128 bytes for
1283 nickname and 256 bytes for channel name.
1285 * Moved the WHOIS printing to the application. The client libary
1286 does not print out the WHOIS information anymore, the application
1287 must do it. Renamed silc_client_command_reply_whois_print to
1288 the silc_client_command_reply_whois_save.
1290 The client's idle time is also sent to the application now, and
1291 the idle is shown on screen.
1293 * Added silc_client_command_reply_identify_save to save the
1294 received IDENTIFY entries.
1296 * Do not check for channel private keys in message sending and
1297 reception if the channel does not have the PRIVKEY mode set.
1298 Affected file lib/silclient/client_channel.c.
1300 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1302 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1303 just surfaced after chaning the JOIN procedure.
1305 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1307 * Added silc_client_get_clients_by_list to get client entries
1308 from Client ID list, that is returned for example by JOIN
1309 and USERS command replies. The application should use this
1310 function for example when JOIN command reply is received to
1311 resolve the clients already on the channel (library does not
1312 do that anymore as USERS command reply is not used in the JOIN
1313 procedure anymore). Affected files lib/silcclient/silcapi.h and
1314 lib/silcclient/idlist.c.
1316 * JOIN command reply and USERS command reply returns now SilcBuffer
1317 pointers instead of unsigned char pointers when returning
1318 the client list and mode list.
1320 * Added <Client ID> argument to the JOIN command reply, mainly
1321 for the server to identify for which client the command was
1322 originally sent. Updated protocol specs accordingly.
1324 * Added SilcDlist private_key pointer to the SilcChannelEntry
1325 in the client to support the channel private keys. Affected
1326 file is lib/silcclient/idlist.h.
1328 * Added SilcChannelPrivateKey argument to the function
1329 silc_client_send_channel_message so that application can choose
1330 to use specific private ke if it wants to. If it is not provided,
1331 the normal channel key is used, unless private keys are set.
1332 In this case the first (key that was added first) is used
1333 as the encryption key.
1335 * Implemented the support for channel private key handling.
1336 Implemented the following functions:
1338 silc_client_add_channel_private_key,
1339 silc_client_del_channel_private_keys,
1340 silc_client_del_channel_private_key,
1341 silc_client_list_channel_private_keys and
1342 silc_client_free_channel_private_keys
1344 Affected file lib/silcclient/client_channel.c.
1346 * Added the support for the private keys in the channel message
1347 sending and encryption and in the message reception and
1348 decryption. Affected funtions are
1349 silc_client_send_channel_message and silc_client_channel_message.
1351 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1353 * Added SKE's key verify callback to the client library's
1354 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1356 * Removed the statement that server (or router) must send USERS
1357 command reply when joining to the channel so that the client
1358 knows who are on the channel. Instead, the client list and
1359 client's mode list is now sent in the JOIN command reply to the
1360 client who joined channel. This is better solution.
1362 * Added function silc_server_get_users_on_channel and function
1363 silc_server_save_users_on_channel to the silcd/server.[ch].
1365 * Removed function silc_server_command_send_users from the
1368 * Do not show topic on the client library anymore. The topic is
1369 sent in the command reply notify to the application and the
1370 application must show the topic now.
1372 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1374 * Added client searching by nickname hash into the IDENTIFY and
1375 WHOIS commands in the server as they were clearly missing from
1376 them. Affected file is silcd/command.c.
1378 * Fixed a bug in private message receiving in the client library.
1379 The remote ID was freed and it wasn't supposed, now it is
1382 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1384 * Minor fix to the channel payload; allocate the data area, as it
1385 needs to be of specific length.
1387 * If the key agreement port is zero then the operating
1388 system will define the bound port. Affected files are
1389 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1391 * Added new function silc_channel_payload_decrypt into the file
1392 lib/silccore/silcchannel.[ch].
1394 * Moved the channel message etc, check from silc_packet_decrypt
1395 to applications. The library calls now a generic
1396 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1397 when the packet is either normal or special. This was done to
1398 allow more wide range of checking that was not allowed when
1399 the code was in library. Now applications can do virtually any
1400 checks to the packet and return to the library the decision how
1401 the packet should be processed. Affected files are
1402 lib/silccore/silcpacket.[ch].
1404 Added silc_server_packet_decrypt_check to the server and
1405 silc_client_packet_decrypt_check to the client library.
1407 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1408 to send with specified source and destination information.
1410 * Channel message delivery between routers was broken after the
1411 channel key distribution was fixed earlier. The channel key
1412 was used be to distributed to other routers as well which is not
1413 allowed by the protocol. Now this is fixed and channel keys
1414 really are cell specific and the channel message delivery between
1415 routers comply with the protocol specification.
1417 * Fixed various commands in server to check also the global list
1418 for the channel entry and not just the local list. The affected
1419 file silcd/command.c.
1421 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1423 * Added assert()s to buffer formatting and unformatting routines
1424 to assert (if --enable-debug) when error occurs. Affected
1425 file: lib/silcutil/silcbuffmt.c.
1427 * Changed to auto-reconnect to check whether the remote host is
1428 router and register the re-connect timeout if it is. It used
1429 to check that whether we are normal server, but router must do
1430 auto-reconnect with another router as well. Affected file
1433 * Removed the [<key len>] option from CMODE command as the cipher
1434 name decides the key length, nowadays. See the defined ciphers
1435 from the protocol specification.
1437 * Added [<hmac>] option to the CMODE command to define the HMAC
1438 for the channel. Added SILC_CMODE_HMAC channel mode.
1440 * Added [<hmac>] option for the JOIN command so that user can
1441 select which HMAC is used to compute the MACs of the channel
1444 * Added Hmac field to the Channel Message Payload. The integrity
1445 of plaintext channel messages are now protected by computing
1446 MAC of the message and attaching the MAC to the payload. The
1447 MAC is encrypted. Now, it is clear that this causes some
1448 overhead to the size of the packet but rationale for this is that
1449 now the receiver can verify whether the channel message decrypted
1450 correctly and also when private keys are set for the channel the
1451 receiver can decrypt the packet with several keys and check from
1452 the MAC which key decrypted the message correctly.
1454 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1455 lib/silccrypt/silccipher.[ch].
1457 * Added silc_hash_len to return the digest length into the
1458 lib/silcrypt/silchash.[ch].
1460 * Rewrote parts of Silc Channel Payload interface in the
1461 lib/silccore/silcchannel.[ch]. The encode function now also
1462 encrypts the packet and parse function decrypts it.
1464 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1466 * Fixed a minor formatting bug in the SKE's key material processing.
1467 It actually might have processed the keys wrong way resulting
1470 * Redefined the mandatory HMAC algorithms and added new algorithms.
1471 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1472 and hmac-md5 truncated to 96 bits. The mandatory is now
1473 hmac-sha1-96. Rest are optional (including the one that used
1474 to be mandatory). Rationale for this is that the truncated HMAC
1475 length is sufficient from security point of view and can actually
1476 make the attack against the HMAC harder. Also, the truncated
1477 HMAC causes less overhead to the packets. See the RFC2104 for
1480 * Added new [hmac] configuration section. The SKE used to use
1481 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1482 is of course wrong. The official names that must be proposed in
1483 the SKE are the ones defined in the protocol specification
1484 (hmac-sha1-96 for example). The user can configure any hmac
1485 using any hash function configured in the [hash] section. At
1486 least, the mandatory must be configured.
1488 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1490 * Added HMAC list to the SKE proposal list. It has now both
1491 hash algorithm list and HMAC list. This makes the protocol
1492 incompatible with previous versions. The SKE now seems to work
1493 the way it is supposed to work, for the first time actually.
1495 * Defined plain Hash algorithms to the protocol specification.
1498 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1500 * Implemented support for key agreement packets into the server.
1501 Added functions silc_server_key_agreement and
1502 silc_server_send_key_agreement. Other than these functions,
1503 server has nothing to do with this packet.
1505 * Added support for private message key packets into the server.
1506 Added functions silc_server_private_message_key and
1507 silc_server_send_private_message_key.
1511 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1512 called in the protocol's final callback instead in the END
1513 protocol state. This makes a little more sense and in the same
1514 time in client we can use the same protocol routines for normal
1515 key exchange and to key agreement packet handling as well.
1517 * Added to both client's and server's KE protocol context the
1518 SilcSKEKeyMaterial pointer to save the key material. We will
1519 bring the key material to the protocol's final callback by doing
1520 this. The final callback must free the key material.
1522 * Added SKE's packet_send callback into client's KE protocol
1523 context so that the caller can choose what packet sending function
1524 is used. This way we can use different packet sending when
1525 doing normal SKE when doing key agreement packet handling (in
1526 the key agreement packet handling we do not want to encrypt
1529 * Implemented the responder side of the key agreement routines
1530 in the client. The client can now bind to specified port and
1531 accept incoming key negotiation. The key material is passed
1532 to the application after the protocol is over.
1534 * Implemented the processing of incoming Key Agreement packet
1535 in the client. Added function silc_client_key_agreement to
1538 * Implemented the intiator side of the key agreement routines
1539 in the client. The client can now initiate key agreement with
1540 another remote client. The key material is passed to the
1541 application after the protocol is over.
1543 * Created client_keyagr.c to include all the key agreement
1546 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1547 SILC_TASK_CALLBACK except that it is not static.
1549 * Created client_notify.c and moved the Notify packet handling
1550 from the client.[ch] into that file.
1552 * Created client_prvmsg.c and moved all private message and
1553 private message key routines from the client.[ch] into that file.
1555 * Create client_channel.c and moved all channel message and
1556 channel private key routines from the client.[ch] into that file.
1558 * Changed silc_client_get_client_by_id_resolve to resolve with
1559 WHOIS command instead of IDENTIFY command, in the file
1560 lib/silclient/idlist.c.
1562 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1564 * Implemented the SKE's responder side to the Client library.
1566 * When FAILURE is received to the protocol do not trust it
1567 blindly. Register a timeout to wait whether the remote closes
1568 the connection as it should do it, only after that process the
1569 actual failure. This was changed to both client and server.
1571 * Added client_internal.h to include some of the structures
1572 there instead of client.h in lib/silcclient/.
1574 * Added function silc_task_unregister_by_callback to unregister
1575 timeouts by the callback function.
1577 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1579 * Some "Incomplete WHOIS info" errors has been appearing on the
1580 log files. Took away the entry->userinfo check from WHOIS
1581 reply sending. The entry->userinfo is now " " if client did not
1582 provide one. I thought this was fixed earlier but something
1583 is wrong still. Let's see if the error still appears.
1585 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1587 * Fixed a minor bug in the login when the channel key is
1588 re-generated in the server. It used to generate the key in
1589 wrong order and thus caused problems in the channel traffic.
1591 * Fixed a minor bug in channel key distsribution after
1592 KICK command. The key was not sent to the router even though
1595 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1597 * Added silc_ske_process_key_material_data as generic routine
1598 to process any key material as the SILC protocol dictates. The
1599 function is used by the actual SKE library but can be used by
1600 applications as well. This relates to the private message keys
1601 and the channel private keys since they must be processed the
1602 same way the normal SILC session keys. The protocol dictates
1603 this. Affected files: lib/silcske/silcske.[ch].
1605 Added also silc_ske_free_key_material to free the
1606 SilcSKEKeyMaterial structure.
1608 * Defined silc_cipher_set_key function to set the key for
1609 cipher without using the object's method function. The affected
1610 files: lib/silccrypt/silccipher.[ch].
1612 * Implemented silc silc_client_add_private_message_key,
1613 silc_client_add_private_message_key_ske,
1614 silc_client_del_private_message_key,
1615 silc_client_list_private_message_keys and
1616 silc_client_free_private_message_keys functions in the
1619 Added functions silc_client_send_private_message_key to send
1620 the Private Message Key payload and silc_client_private_message_key
1621 to handle incoming Private Message Key payload.
1623 * Added Cipher field to the Private Message Key payload to set
1624 the cipher to be used. If ignored, the default cipher defined
1625 in the SILC protocol (aes-256-cbc) is used.
1627 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1629 * Removed lib/silcclient/ops.h file.
1631 Redefined parts of the SILC Client Library API. Created new
1632 file silcapi.h that deprecates the ops.h file and defines the
1633 published Client Library API. Defined also private message key
1634 API and channel private key API into the file.
1636 This is the file that the application must include from the
1637 SILC Client Library. Other files need not be included by
1638 the application anymore.
1640 * Added new key_agreement client operation callback and also
1641 defined the Key Agreement library API for the application.
1643 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1646 is used by clients to request key negotiation between another
1647 client in the SILC network. If the negotiation is started it
1648 is performed using the SKE protocol. The result of the
1649 negotiation, the secret key material, can be used for example
1650 as private message key.
1652 Implemented the Key Agreement payload into the files
1653 lib/silccore/silauth.[ch].
1655 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1657 * Redefined ciphers for the SILC protocol. Added some new ciphers
1658 and defined the key lengths for the algorithms. Changed the
1659 code accordingly. The default key length is now 256 bits.
1661 * Fixed SKE key distribution function silc_ske_process_key_material
1662 when the key length is more than 128 bits. The default key
1663 length in SILC is now 256 bits.
1665 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1666 to indicate unsupported algorithm.
1668 * Renamed rijndael.c to aes.c and all functions as well.
1670 * Fixed a long standing channel key setting bug in client library.
1671 Weird that it has never surfaced before.
1673 * Fixed bug in channel deletion. If the entire channel is removed
1674 then it must also delete the references of the channel entry
1675 from the client's channel list as the client's channel entry and
1676 the channel's client entry share same memory.
1678 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1680 * Implemented CONNECT and SHUTDOWN commands in the client.
1682 * Implemented CLOSE command to the client.
1684 * Added the function silc_idlist_find_server_by_name into the
1685 files silcd/idlist.[ch].
1687 Added the function silc_idlist_find_server_by_conn into the
1688 files silcd/idlist.[ch].
1690 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1692 * DIE command was renamed to SHUTDOWN. Updated the both code
1695 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1696 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1698 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1701 * Added function silc_server_create_connection function to create
1702 connection to remote router. My server implementation actually
1703 does not allow router to connect to normal server (it expects
1704 that normal server always initiates the connection to the router)
1705 so the CONNECT command is only good for connecting to another
1708 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1710 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1711 or some other client was kicked from the channel.
1713 Implemented the handling of the notify type to both client
1716 Implemented silc_server_send_notify_kicked to send the KICKED
1717 notify. It is used to send it to the server's primary router.
1719 * Implemented the KICK command into server and client.
1721 * Added `query' argument to the silc_idlist_get_client function
1722 to indicate whether to query the client from server or not if
1725 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1726 to indicate that the client is not channel founder.
1730 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1732 * Removed the rng context from SilcPacketContext structure and
1733 changed that the packet routine uses the Global RNG API.
1735 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1737 * Added support for quit message that client can "leave" on the
1738 channel when it quits the SILC. It is ditributed inside the
1739 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1741 Added silc_server_free_client_data that will take the
1742 signoff message as argument.
1744 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1746 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1748 * Updated parts of the protocol specification to keep it up
1751 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1753 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1754 payloads in one packet.
1756 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1757 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1758 use now the new List flag.
1760 * Also deprecated the following packet types: REPLACE_ID,
1761 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1763 * Added list support for Notify packet in server.
1765 * Added silc_server_send_notify_channel_change to send the
1766 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1767 the silc_server_send_replace_id.
1769 * Added silc_server_send_notify_nick_change to send the
1770 NICK_CHANGE notify type. Deprecates the function
1771 silc_server_send_replace_id.
1773 * Added silc_server_send_notify_join to send the JOIN notify type.
1774 Deprecates the function silc_server_send_new_channel_user.
1776 * Added silc_server_send_notify_leave to send LEAVE notify type.
1777 Deprecates the function silc_server_send_remove_channel_user.
1779 * Added silc_server_send_notify_cmode and
1780 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1781 types. Deprecates the silc_server_send_set_mode function.
1783 * Added SERVER_SIGNOFF notify type to indicate that server has
1784 quit. This means that all clients on the channel from that
1785 server will drop. This can be also used when netsplit happens.
1787 Deprecated REMOVE_ID packet type since it is not needed anymore
1790 Added silc_server_send_notify_server_signoff to send the
1791 SERVER_SIGNOFF notify type. Deprecates the function
1792 silc_server_send_remove_id.
1794 Added also silc_server_send_notify_signoff to send the
1795 SIGNOFF notify type.
1797 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1798 SILC protocol from this day on. Changed the protocol
1799 specification as well.
1801 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1802 notify type. It is used between routers to notify about
1803 topic changes on a channel.
1805 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1808 * Partly updated the protocol specification to comply with the
1809 changes now made. It is still though a bit outdated.
1811 * The JOIN notify type now takes one extra argument <Channel ID>.
1812 The packet used to be destined to the channel but now the
1813 JOIN type may be sent as list thus it is impossible to
1814 destine it to any specific channel. By adding this argument
1815 it is again possible.
1817 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1819 * Added CREDITS file. The CHANGES and CREDITS file will appear
1820 in the distribution as well.
1822 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1825 types in the server's silcd/packet_receive.c.
1827 * Implemented CMODE and CUMODE to work in router environment.
1829 * Fixed minor encoding and decoding buglet from the
1830 lib/silccore/silcmode.c.
1832 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1835 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1837 * Changed all SilcConfigServer* and silc_config_server* to
1838 SilcServerConfig* and silc_server_config*, respectively.
1841 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1843 * Associated the ID (client or server ID) to the Authentication
1844 Payload to avoid any possibility of forging. Updated the
1845 protocol specification and the code accordingly.
1847 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1849 * The RSA key length is now save to the RsaKey context in the
1850 key generation process in lib/silccrypt/rsa.c. The key length
1851 is now used to figure out the maximum size of the block allowed
1852 to be encrypted/signed.
1854 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1855 is equivalent to the silc_mp_mp2bin but does not allocate any
1858 * Changed silc_mp_mp2bin API to take length argument. If it is
1859 non-zero then the buffer is allocated that large. If zero, then
1860 the size is approximated using silc_mp_sizeinbase, which however
1863 * Created Global RNG API which is global RNG that application can
1864 initialize. After initializing, any routine anywhere in the
1865 code (including library) can use RNG without allocating a new
1866 RNG object. This was done to allow this sort of use of the
1867 RNG in code that has no chance to allocate RNG object. All
1868 applications currently allocate this and many routines in the
1869 library use this. Affected file lib/silccrypt/silcrng.[ch].
1871 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1872 it to use the Global RNG API.
1874 * Defined Authentication Payload into protocol specification that
1875 is used during SILC session to authenticate entities. It is
1876 used for example by client to authenticate itself to the server
1877 to obtain server operator privileges.
1879 Implemented this payload into the lib/silccore/silcauth.[ch].
1880 Implemented also routines for public key based authentication
1881 as the new protocol specification dictates.
1883 Moved definitions of different authentication methods from
1884 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1886 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1887 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1888 silc_pkcs_verify_with_hash functions into the file
1889 lib/silccrypt/silcpkcs.[ch].
1891 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1893 * The client entry's userinfo pointer must be always valid.
1894 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1895 will fail since it requires the userinfo. Now, the userinfo
1896 is allocated as "" if actual userinfo does not exist. Actually,
1897 it must exist and it is totally Ok to drop client connections
1898 that does not announce the userinfo. However, we will make
1899 this workaround for now.
1901 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1902 to return the remote port by socket.
1904 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1906 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1907 SILC_SERVER_PENDING_EXEC and added an new macro
1908 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1909 data or when error occurs while processing the pending command.
1911 Added new argument `destructor' into silc_server_command_pending
1912 and to the SilcServerCommandPending object. This destructor is
1913 now called after calling the pending callback or if error occurs
1914 immediately. If error occurs the actual pending callback won't
1915 be called at all - only the destructor. The destructor may be
1916 NULL if destructor is not needed.
1918 All this applies for client library code as well. Similar
1919 changes were made there as well for the pending commands.
1921 In the client, the application must now allocate the
1922 SilcClientCommandContext with the silc_client_command_alloc
1925 * Added reference counter to the SilcServerCommandContext. Added
1926 function silc_server_command_alloc and silc_server_command_dup
1929 Same type of functions added to the client library for the same
1932 * Removed the cmd_ident from IDListData away since it is now
1933 global for all connections. It is the command identifier used
1934 in command sending and with pending commands. The affected file
1937 * Added reference counter to the SilcSocketConnection objecet to
1938 indicate the usage count of the object. The object won't be
1939 freed untill the reference counter hits zero. Currently only
1940 server uses this, and client ignores it. The client must be
1941 set to use this too later. The affected files are
1942 lib/silccore/silcsockconn.[ch]. Added also the function
1943 silc_socket_dup to increase the reference counter.
1945 This was mainly added because it is possible that the socket
1946 is removed underneath of pending command or other async
1947 operation. Now it won't be free'd and proper DISCONNECTING
1948 flags, etc. can be set to avoid sending data to connection that
1949 is not valid anymore.
1951 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1952 the connection. After that it sets SILC_SET_DISCONNECTED.
1953 It is, however, possible that the socket data is not still freed.
1954 The silc_server_packet_process now checks that data is not
1955 read or written to connection that is DISCONNECTED. The socket
1956 get's freed when the reference counter hits zero.
1958 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1960 * Changed the client operation API: channel_message operation's
1961 `sender' is now the client entry of the sender, not the nickname
1962 and the `channel' is the channel entry, not the channel name.
1964 In the private_message operation the `sender' is now also the
1965 client entry of the sender not the nickname.
1967 Affected file is lib/silcclient/ops.h and all applications
1968 using the client operations.
1970 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1972 * Moved the calling of ops->connect() from connect_to_server_final
1973 into receive_new_id functin since that is the point when the
1974 client is actually allowed to send traffic to network. The
1975 affected file is lib/silcclient/client.c.
1977 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1979 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1980 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1981 (if needs broadcasting) instead of broadcasting the packets one
1982 by one which would make a burst in the network traffic.
1984 * Added `broadcast' argument to the functions in silcd/server.[ch]
1985 silc_server_create_new_channel[_with_id] to indicate whether
1986 to send New Channel packet to primary router.
1988 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1990 * Added new function into the silcd/server.[ch] files:
1991 silc_server_create_new_channel_with_id to create new channel with
1992 already existing Channel ID.
1994 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
1995 lib/silccore/silcpacket.h. This packet is used t send list of
1996 Set Mode payloads inside one packet. Server uses this to set
1997 the modes for the channels and clients on those channels, that it
1998 announced to the router when it connected to it. The protocol
1999 specification has been updated accordingly.
2001 * The silc_server_new_channel did not handle the packet coming
2002 from normal server as it normally does not send that. However,
2003 when it announces its channels it does send it. Implemented
2004 the support for that.
2006 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2007 into the file lib/silccore/id.h.
2009 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2011 * Fixed memory leaks in the functions silc_idlist_del_client,
2012 silc_idlist_del_channel and silc_idlist_del_server in the file
2013 silcd/idlist.c. All of those leaked like a sieve.
2015 * Fixed some small memory leaks in the client's function
2016 silc_client_notify_by_server.
2018 * Added functions into silcd/server.c: silc_server_announce_clients,
2019 silc_server_announce_channels and silc_server_announce_server.
2020 These functions are used by normal and router server to announce
2021 to its primary router about clients, channels and servers (when
2022 router) that we own. This is done after we've connected to the
2025 These functions effectively implements the following packet types:
2026 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2027 and SILC_PACKET_NEW_ID_LIST.
2029 * Added new functions into the silcd/packet_receive.[ch]:
2030 silc_server_new_id_list, silc_server_new_channel_list and
2031 silc_server_new_channel_user_list to handle the incoming
2032 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2034 * Added support of changing Channel ID in the function
2035 silc_server_replace_id. If the server that announces a channel
2036 to the router already exists in the router (with same name but
2037 with different Channel ID), router is responsible to send
2038 Replace ID packet to the server and force the server to change
2039 the Channel ID to the one router has.
2041 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2042 client that the Channel ID has been changed by the router. The
2043 normal server sends this to the client. Client must start using
2044 the new Channel ID as the channel's ID.
2046 Implemented handling of this new type into lib/silcclient/client.c
2047 into the function silc_client_notify_by_server.
2049 * Added new function silc_idlist_replace_channel_id into the files
2050 silcd/idlist.[ch] to replace the Channel ID.
2052 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2054 * Call silc_server_command_identify_check always when processing
2055 the IDENTIFY command in silcd/command.c
2057 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2059 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2060 send keepalive packets. The packet can be sent by clients,
2061 servers and routers.
2063 Added function silc_socket_set_heartbeat into the file
2064 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2065 If not set, the heartbeat is not performed. The actual
2066 heartbeat is implemented in the low level socket connection
2067 library. However, application is responsible of actually
2070 Added silc_server_send_heartbeat to send the actual heartbeat
2071 packet into silcd/packet_send.[ch]. Server now performs
2072 keepalive with all connections.
2074 * Added silc_task_get_first function into lib/silcutil/silctask.c
2075 to return the timeout task with shortest timeout. There was a bug
2076 in task unregistration that caused problems. TODO has been
2077 updated to include that task system must be rewritten.
2079 * The client library will now resolve the client information when
2080 receiving JOIN notify from server for client that we know but
2081 have incomplete information.
2083 * Rewrote parts of silc_server_remove_from_channels and
2084 silc_server_remove_from_one_channel as they did not remove the
2085 channel in some circumstances even though they should've.
2087 * Encryption problem encountered in server:
2089 The LEAVE command used to send the Channel Key packet to the
2090 router immediately after generating it. However, the code
2091 had earlier sent Remove Channel user packet but not immediately,
2092 ie. it was put to queue. The order of packets in the router
2093 was that Channel Key packet was first and Remove Channel User
2094 packet was second, even though they were encrypted in the
2095 reverse order. For this reason, MAC check failed. Now, this
2096 is fixed by not sending the Channel Key packet immediately but
2097 putting it to queue. However, this is more fundamental problem:
2098 packets that are in queue should actually not be encrypted
2099 because packets that are sent immediately gets encrypted
2100 actually with wrong IV (and thus MAC check fails). So, packets
2101 that are in queue should be encrypted when they are sent to
2102 the wire and not when they put to the queue.
2104 However, the problem is that the current system has not been
2105 designed to work that way. Instead, the packet is encrypted
2106 as soon as possible and left to the queue. The queue is then
2107 just purged into wire. There won't be any fixes for this
2108 any time soon. So, the current semantic for packet sending
2111 o If you send packet to remote host and do not force the send
2112 (the packet will be in queue) then all subsequent packets to the
2113 same remote host must also be put to the queue. Only after the
2114 queue has been purged is it safe again to force the packet
2117 o If you send all packets immediately then it safe to send
2118 any of subsequent packets through the queue, however, after
2119 the first packet is put to queue then any subsequent packets
2120 must also be put to the queue.
2122 Follow these rules and everything works fine.
2124 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2126 * Added new function silc_server_remove_clients_by_server to
2127 remove all client entries from ID list when the server connection
2128 is lost. In this case it is also important to invalidate all
2129 client entires as they hold the invalid server entry. This
2130 fixes fatal bug when server has lost connection and will reconnect
2133 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2135 * Made some sanity checks to silc_server_daemonise like to check
2136 whether the requested user and group actually exists.
2138 * Added sanity check to SKE's silc_ske_responder_finish to check
2139 that the public and private key actually is valid.
2141 * Invalidate the client's nickname when receiving Replace ID
2142 packet and the Client ID is being replaced. This means that the
2143 server will query the nickname if someone needs it (client)
2146 * Sort the ID Cache in client library when the ID Cache data
2147 has changed (needs sorting).
2149 * Do not allow for SILC client to create several connections to
2150 several servers. The client does not support windows right now
2151 and generating multiple connections causes weird behaviour.
2153 Irssi-silc client does support windows and can handle several
2154 connections without problems, see: www.irssi.org and SILC plugin.
2156 * Fixed some places where client was added to the IDList. The
2157 rule of thumb is following (in order to get everything right):
2158 If the client is directly connected local client then the
2159 `connection' argument must be set and `router' argument must be
2160 NULL to silc_idlist_add_client function. If the client is not
2161 directly connected client then the `router' argument must
2162 bet set and the `connection' argument must be NULL to the
2163 silc_idlist_add_client function.
2165 * The funtion silc_server_packet_send_local_channel actually did
2166 not check whether the client was locally connected or not. It
2167 does that now. Fixed a bug related to LEAVE command.
2169 * Fixed Remove Channel User payload parsing bug in server's
2170 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2172 * The server's silc_server_save_channel_key now checks also the
2173 global ID list for the channel as it might not be in the local
2174 list. Fixed a bug related to LEAVE command.
2176 * Is this the end of the [<unknown>] buglet that has been lurking
2177 around for a long time? A little for loop fix in server's
2178 silc_server_command_whois_parse that is used by both IDENTIFY
2179 and WHOIS command. At least, this was a clear bug and a cause
2180 of one type of [<unknown>] buglet.
2182 * WHOIS and IDENTIFY commands call the function
2183 silc_server_command_[whois/identify]_check function even if
2184 we are not router server.
2186 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2188 * Added --with-gmp configuration option. If set the GMP
2189 is always compiled in the SILC source tree. If not set then
2190 it is checked whether the system has the GMP3 installed. If
2191 it has then the GMP won't be compiled (the system's headers
2192 and library is used), if it doesn't have it then the GMP is
2193 compiled in the SILC source tree.
2195 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2197 * Changed RSA private exponent generation to what PKCS #1
2198 suggests. We try to find the smallest possible d by doing
2199 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2200 not security fix but optimization.
2202 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2204 * Added new config entry [Identity] to fork the server and run
2205 it as specific user and group. A patch from Bostik.
2207 * Imported Dotconf configuration library into lib/dotconf.
2208 This will be used to create the SILC configuration files later.
2209 It will appear in the distsribution after this commit.
2211 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2213 * A big code auditing weekend happening. Auditing code for
2214 obvious mistakes, bugs and errors. Also, removing any code
2217 Removed files for being obsolete:
2219 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2220 inline in the file lib/silcutil/silcbuffer.h)
2222 o lib/silcutil/silcbufutil.c (the header has inline versions)
2224 Changed code to fix possible error conditions:
2226 o The buffer formatting routines now check that the destination
2227 buffer really has enough space to add the data. This applies for
2228 both buffer formatting and unformatting
2229 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2230 unformatting was changed to accomodate following rules:
2231 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2232 sent to the function while XXX_*STRING will not allocate or copy
2233 the data into the buffer. Instead it sets the pointer from the
2234 buffer into the pointer sent as argument (XXX_*STRING used to
2235 require that the pointer must be allocated already). This change
2236 makes this whole thing a bit more consistent and more optimized
2237 (note that the data returned in the unformatting with XXX_*STRING
2238 must not be freed now). The routines return now -1 on error.
2240 o Tried to find all code that use buffer_format and buffer_unformat
2241 and added return value checking to prevent formatting and
2242 especially unformatting errors and possible subsequent fatal
2245 o Changed ske->x and ske->KEY to mallocated pointers in
2246 lib/silcske/silcske.h. Fixed possible data and memory leak.
2248 o Added return value checking to all *_parse* functions. Fixed
2249 many memory leaks as well.
2251 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2252 so that buffer overflows would not happen. All code now also
2253 checks the return value as it can fail.
2255 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2257 * Added reconnection support to server if the normal server looses
2258 its connection to the router (for example if router is rebooted).
2259 The server performs normal reconnection strategy implemented
2260 to the server. Affected file silcd/server.c.
2262 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2264 * Added new packet type SILC_PACKET_SET_MODE that is used to
2265 distribute the information about changed modes (for clients,
2266 channels and clients channel modes) to all routers in the
2267 network. Updated the protocol specification accordingly.
2269 Added functions into silcd/packet_send.c and
2270 silcd/packet_receive.c: silc_server_send_set_mode,
2271 silc_server_set_mode.
2273 Added new files silcmode.[ch] into lib/silccore that implements
2274 the encoding and decoding of Set Mode Payload. Added new type
2275 SilcSetModePayload. Moved the definitions of different modes
2276 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2278 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2280 * Oops, a little mistake in server's connection authentication
2281 protocol. The protocol is not ended with FAILURE but with
2282 SUCCESS if the authentication is Ok. :) Affected file is
2285 * Implemented NICK_CHANGE notify handling in server in the file
2286 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2287 the local clients on the channel. After the changing nickname
2288 in router environment snhould work and the [<unknown>] nickname
2289 should appear no more.
2291 The silc_server_replace_id function that receives the Replace ID
2292 payload now sends the NICK_CHANGE notify type also in the file
2293 silcd/packet_receive.c
2295 * Changed WHOIS and IDENTIFY command to support the maximum amount
2296 of arguments defined in protocol specs (3328 arguments). This
2297 fixed a bug that caused problems when there were more than three
2300 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2302 * Added extra parameter, command identifier, to the
2303 silc_client_send_command so that explicit command identifier
2306 Changed that ID list routines uses specific command identifier
2307 when sending WHOIS/IDENTIFY requests to the server so that they
2308 can be identified when the reply comes back.
2310 Affected files lib/silcclient/command.[ch],
2311 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2313 * Added `sender' argument to silc_server_packet_send_to_channel
2314 to indicaet the sender who originally sent the packet to us
2315 that we are now re-sending. Ignored if NULL. Affected file
2316 silcd/packet_send.[ch].
2318 * Added some server statistics support in silcd/server_internal.h
2319 SilcServerStatistics structure and around the server code. Also
2320 send some nice statistics information when client is connecting
2323 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2325 * Fixed channel ID decoding in server's JOIN command reply in
2326 silcd/command_reply.c
2328 * Fixed braodcasting of replace ID payload to not to send it if
2329 we are standalone server in silcd/packet_receive.c.
2331 * Fixed all channel message sending routines to not to send
2332 packets to clients that has router set, since they are routed
2333 separately in the same function earlier. Affects file
2334 silcd/packet_send.c and all channel packet sending functions.
2336 * In USERS reply, res_argv[i] are not allocated, the table
2337 is allocated. Thus changed that free the table, not its
2340 * In server's whois_check and identify_check if the client is
2341 locally connected do not send any WHOIS commands - they are not
2344 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2346 * Fixed some minor bugs in client when sending WHOIS command. The
2347 arguments was in wrong order.
2349 * Removed statis function add_to_channel from server in
2350 silcd/command.c that was previously used with the joining but
2353 * Tested USERS command in router environment successfully with two
2354 routers, two servers and two clients.
2356 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2358 * Reorganized the USERS command and command reply in client library
2359 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2360 When the command is given by user we register a pending command
2361 callback that will reprocess the command after the reply has been
2362 received from the server. When reprocessing the packet we then
2363 display the information. Thus, the USERS information is displayed
2364 now in the command callback instead of in the command reply
2365 callback. The processing of the command is same as previously
2366 when server has sent the command reply in the JOINing process.
2368 * Added to USERS command in silcd/command_reply.c to join the client,
2369 we didn't use to know about, to the channel after we've created
2370 a client entry for it. Also, for clienet we did know already still
2371 check whether it is on the channel or not and add it if not.
2373 * Removed silc_server_command_join_notify as the function and its
2376 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2378 * Changed the client's pending command handling to the same as the
2379 server's pending command handling. It is also now possible to
2380 execute command reply functions from other command reply
2381 function as the function callbacks for commands and command
2382 replies are one and same. The pending commands are not static
2383 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2384 in client connection context. Thus, pending commands are server
2385 connection specific as it is convenient.
2387 Changed the function silc_client_command_pending and
2388 silc_client_command_pending_del and added new function
2389 silc_client_command_pending_check. Removed the
2390 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2393 * Added cmd_ident, current command identifier, to the client
2394 connection context in lib/silcclient/client.h to keep track on
2395 command identifiers used in command sending. Client's command reply
2396 function handling now supports the mandatory command identifiers.
2398 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2399 funtions in client to fully support pending command callbacks.
2401 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2402 as one of the arguments to the application in the command reply
2405 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2406 before first releasing SILC but came back. Now it is removed again
2407 and should come back nomore. The FORWARDED flag was used only
2408 by the JOINing procedure by forwarding the command packet to router.
2409 Now, the JOINing procedure has been changed to more generic (due
2410 to various router environment issues) and FORWARDED is not needed
2411 anymore for anything. The protocol specification is yet to be
2414 Now, removed silc_server_packet_forward from server and the flag
2415 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2417 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2419 * Renamed NAMES command to USERS command. The NAMES was named that
2420 due to historical reasons. Now it is renamed. Also, rewrote
2421 parts of the USERS command. The nickname list is not sent anymore
2422 by the server. Only Client ID and mode lists are sent in the USERS
2423 command. Changed this also to the protocol specification.
2425 The client now resolves the names and stuff after it receives
2426 the USERS list from the server when joining to the channel.
2428 * WHOIS and IDENTIFY commands has been changed to support multiple
2429 Client ID's per command. One can now search for multiple users
2430 in the network by sending only one WHOIS or IDENTIFY command.
2431 Changed the code and the protocol specifications.
2433 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2434 uses silc_server_command_whois_parse to parse the request. */
2436 * If normal server, do not parse the WHOIS and IDENTIFY requests
2437 before sending it to the router. Saves some time.
2439 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2441 * Fixed JOIN command on client library. Wrong number of arguments
2442 used to crash the client.
2444 * Added silc_server_channel_has_global function to check whether
2445 channel has global users or not.
2447 * Added silc_server_channel_has_local function to check whether channel
2448 has locally connected clients on the channel.
2450 * The silc_server_remove_from_one_channel now checks whether the
2451 channel has global users or not after given client was removed from
2452 the channel. It also checks whether the channel has local clients
2453 on the channel anymore. If it does not have then the channel entry
2454 is removed as it is not needed anymore.
2456 * The silc_server_notify now checks on JOIN notify whether the joining
2457 client is one of locally connected or global. If it is global then
2458 the channel has now global users on the channel and that is marked
2459 to the channel entry. Also, it now saves the global client to
2460 global list who is joining and JOINs it to the channel. This is
2461 for normal server, that is.
2463 Changed silc_server_send_notify_on_channel,
2464 silc_server_packet_relay_to_channel and
2465 silc_server_packet_send_to_channel check if we are normal server
2466 and client has router set (ie. global client) do not send the
2467 message to that client, as it is already routed to our router.
2469 * Implemented LEAVE notify type handling in silc_server_notify
2472 * Tested LEAVE command in router environment successfully. Tested
2473 with two routers, two servers and two clients.
2477 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2479 * Implemented SIGNOFF notify type handling in silc_server_notify
2482 * silc_server_remove_id now removes the client entry from all channels
2483 it has joined and thusly sends SIGNOFF notify type.
2485 * Rewrote the NAMES list generation in server by removing two excess
2486 loops. The lists are created now inside one loop.
2488 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2490 * silc_server_remove_channel_user checks now also global list
2491 for channel and client.
2493 * silc_server_new_channel_user checks now both local and global
2494 list for channel and client. Fixed a bug in client id decoding.
2495 Used to decode wrong buffer.
2497 * silc_server_channel_message checks now both local and global
2498 list for channel entry.
2500 * Tested channel joining (hence JOIN) in router environment
2501 successfully. Tested with two routers, two servers and two
2504 * Tested channel message sending in router environment successfully.
2506 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2508 * Added silc_server_save_channel_key into server.[ch] to save the
2509 received channel key in Channel Key payload processing. It is
2510 also used in JOIN command reply handling.
2512 Equivalent function silc_client_save_channel_key added into
2513 client.[ch] into client library.
2515 * Changed JOIN command reply to send information whether the channel
2516 was created or not (is existing already) and the channel key
2517 payload. Changed protocol specs accordingly.
2519 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2520 the request was sent by ID and not by nickname. Crashed on
2523 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2525 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2526 now correctly save the received data.
2528 * silc_server_free_sock_user_data now notifies routers in the
2529 network about entities leaving the network.
2531 At the same time implemented functions silc_server_remove_id
2532 and silc_server_send_remove_id to receive and send REMOVE_ID
2533 packets. The packet is used to notify routers in the network
2534 about leaving entities. The ID removed will become invalid in
2537 * Added function silc_idlist_del_server into server. Removes and
2538 free's server entry from ID list.
2540 * silc_server_private_message function now checks, if we are router,
2541 that the destination ID really is valid ID, naturally.
2543 * In router when NEW_ID packet is received (for new client) the
2544 hash of the Client ID is saved in the ID Cache but the
2545 client->nickname is set to NULL, instead of putting the hash
2548 IDENTIFY command now also checks that client->nickname must be
2549 valid. If it is not if will request the data from the server who
2550 owns the client. Added new function
2551 silc_server_command_identify_check.
2553 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2554 to set the command to already allocated Command Payload.
2556 * Tested private message sending in router environment with two
2557 routers, two servers and two clients. Fixed minor bugs and now
2560 * Fixed segfault from client's NAMES command. Used to crash if
2563 * Forwarded packets must not be routed even if it is not destined
2564 to the receiver. Changed server code comply with this.
2566 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2568 * Added `require_reverse_mapping' boolean value to ServerParams
2569 structure. If TRUE (not default) the server will require that
2570 the connecting host has fully qualified domain name.
2572 If the reverse mapping is not required and hostname could not be
2573 found the IP address is used as hostname.
2575 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2577 * Implemented version string checking to both client and server.
2578 The check is incomplete currently due to the abnormal version
2579 strings used in development version of SILC.
2581 * Changed all command functions in server to use the new
2584 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2586 * Changed char *data to unsigned char *data in ID Cache system to
2587 support binary data as ID Cache data. Changed code to support
2588 binary data in lib/silccore/idcache.c.
2590 * Renamed silc_server_packet_relay_command_reply to
2591 silc_server_command_reply as it is normal packet receiving
2592 function. Rewrote the function to accept command replys for
2593 servers and not only for clients.
2595 * Mark remote router always as registered server if we are connecting
2596 to it. Otherwise, commands sent by the router to us are ignored.
2598 * All ID List find routines now returns the ID Cache Entry pointer
2599 as well if requested.
2601 * WHOIS command works now in router environment, tested with two
2602 routers, two servers and two clients.
2604 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2605 in router environment (as it is almost equivalent to WHOIS) but
2606 hasn't been tested thoroughly. Added new functions:
2608 silc_server_command_identify_parse
2609 silc_server_command_identify_send_reply
2610 silc_server_command_identify_from_client
2611 silc_server_command_identify_from_server
2613 * Disabled route cache adding because adding two different ID's with
2614 same IP replaces the old cache entry thus giving wrong route.
2615 The entry->router->connection is always the fastest route anyway
2616 so route cache may not be needed. Of course, new routes maybe
2617 established after receiving the ID when the entry->router->connection
2618 might not be anymore the most optimal.
2620 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2622 * Add route cache for received ID for fast routing.
2624 * Added silc_server_packet_route to route received packet on router
2625 that is not destined to us.
2627 * Renamed silc_server_get_route to silc_server_route_get.
2629 * Added id_string and id_string_len fields into SilcServer to
2630 include encoded ServerID for fast comparing without excess
2631 encoding of the ID's.
2633 * Cleaned up WHOIS command on server side. Added following static
2636 silc_server_command_whois_parse
2637 silc_server_command_whois_check
2638 silc_server_command_whois_send_reply
2639 silc_server_command_whois_from_client
2640 silc_server_command_whois_from_server
2642 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2643 arguments in command replies. All command functions should be
2644 updated to use this macro.
2646 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2648 * Minor typo fixes on command reply handling on server.
2650 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2652 * Added silc_server_command_add_to_channel internal routine to add
2653 the client to the channel after router has created the channel and
2654 sent command reply to the server.
2656 * Added generic silc_server_send_command to send any command from
2659 * Use static buffer with ID rendering instead of duplicating data.
2661 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2663 * Fixed a channel user mode bug when joining to a channel server gave
2664 everybody channel founder rights, oops.
2666 * We mark ourselves as the router of the incoming server connection
2667 if we are router ourselves. This way we can check in some packet
2668 sending functions whether it is locally connected server. For
2669 incoming router connections we put NULL.
2671 * For router sending packets locally means now always sending the
2672 packet cell wide; to local clients and local servers. For normal
2673 server sending packet locally means sending it to only local
2676 * Fixed the JOIN command to really work in router environment. If the
2677 channel is created it is always created by the router. Router is
2678 also responsible of making the initial joining to the channel,
2679 sending JOIN notify to the sending server and distributing
2680 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2681 does not exist server doesn't do anything else but forward the
2682 command to the router which performs everything.
2684 * Added silc_server_send_channel_key function to send the Channel Key
2687 * Added silc_server_create_channel_key to create new channel key. The
2688 channel key is now re-generated everytime someone joins or leaves
2689 a channel, as protocol dictates. Note: channel->key_len is the
2692 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2694 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2695 packet_receive.[ch] to separate packet sending and receiving
2696 routines. The server.[ch] now includes everything else including
2697 actual packet processing (writing and reading data) and other
2700 Renamed silc_server_private_message_send_internal to
2701 silc_server_send_private_message. The routine is still though
2702 used only to relay private messages as server does not send
2703 private messages itself.
2705 Renamed silc_server_new_channel to silc_server_create_new_channel
2706 and added new function sicl_server_new_channel that handles the
2707 incoming New Channel packet. Added also new sending function
2708 silc_server_send_new_channel to send New Channel Payload.
2710 * Added new function silc_server_notify to process incoming notify
2711 packet to the server/router. Server may then relay the notify
2712 to clients if needed.
2714 * Added new function silc_server_new_channel_user to process incoming
2715 New Channel User packet. Router will redistribute the packet and
2716 send JOIN notify to its local clients and locally connected servers
2717 if needed. Normal server will send JOIN notify to its local client
2718 on same channel when received this packet. Added also corresponding
2719 sending function silc_server_send_new_channel_user to sent the
2722 * Added boolean route argument to send_notif_to_channel and
2723 packet_send_to_channel functions to attempt to route the packet
2724 if it is TRUE and send only locally if it is FALSE.
2726 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2728 * silc_server_replace_id now broadcasts the received replace ID
2729 packet if it is not broadcast packet already. The router must
2730 broadcast to inform other routers about changed ID.
2732 * Added backpointer to server's router into SilcServer context in
2733 silcd/server_internal.h.
2735 * Fixed silc_server_packet_broadcast to send correct broadcast
2738 * The channel key is now distributed to the local client as soon
2739 as it is received from the router (in router environment) so that
2740 no other packet may be sent for the channel until client has
2743 * silc_server_remove_channel_user now broadcasts the received
2744 Remove Channel User packet if it is not broadcast packet already.
2745 The router must broadcast to inform other routers about removed
2748 * Added users field into SilcPacketContext that is a reference count
2749 of the context. One can increase the reference count by calling
2750 silc_packet_context_dup which is now changed to just increase the
2751 reference count instead of duplicating the data. The reference
2752 count is decresed by calling silc_packet_context_free that will
2753 free the data after the reference count hits zero.
2755 For now on the packet context and everything allocated into it
2756 (including the raw packet from network) must be freed by calling
2757 the new silc_packet_context_free function. Added also new function
2758 silc_packet_context_alloc that must be used now to allocate the
2759 context. This also means that if a routine is asynchronous from
2760 silc_[client/server]_packet_parse_type the packet context must
2761 be duplicated by calling silc_packet_context_dup. Otherwise it
2762 gets free'd after silc_[client/server]_packet_parse_type returns.
2763 Also, one must remember that if packet is duplicated then its
2764 reference count must be decresed by calling the free function as
2765 many times as it was duplicated.
2767 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2768 from both client and server.
2770 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2772 * Made joining to a channel working in router environment.
2774 * Cleaned up JOIN command on server side and create function
2775 silc_server_command_join_channel internal routine to make the
2778 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2780 * Changed silc_command_pending list to SilcDList. Also, added
2781 `ident' field to SilcServerCommandPending structure to identify
2782 the reply and to call correct callback.
2784 Added silc_server_command_pending_check function to replace the
2785 corresnponding macro. The silc_command_pending list is not
2788 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2789 to set identifier to previously allocated Command Payload. It
2790 is used to set identifier for command when resending Command
2793 * Added silc_command_payload_encode_payload to encode Command
2794 Payload buffer from SilcCommandPayload structure.
2796 * Added silc_argument_payload_encode_payload to encode Argument
2797 payload buffer from SilcArgumentPayload structure.
2799 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2801 * Changed WHOIS command to support router connection on server side.
2802 The whois request is always sent to router unless the server is
2803 standalone server. After server has received the reply from the
2804 router will it send the reply to the client.
2806 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2807 broadcast received broadcast packet. The function is used only
2808 by router. The broadcast packet is always sent to the router's
2811 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2812 render given ID to printable string, for log files for example.
2814 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2816 * Made basic router to router connections working. At least they
2817 can now connect to each other but nothing really works the way
2818 they are supposed - yet.
2820 * Added new initiator token to RouterConnection configuration
2821 file in silcd/serverconfig.[ch]. It is used to tell whether we
2822 are the initiator to the remote router or whether we'll expect
2823 the other end to connect.
2825 * Moved registering of listener task to silc_server_init, hence
2826 the server starts listenning as soon as it is run, even if it
2827 does not have connections to other routers. Let's see how well
2830 * Changed default connection retry timeouts for more suitable in
2833 * Removed cipher and such arguments from silc_idlist_add_client
2834 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2835 Added new function silc_idlist_add_data to add the keys and stuff
2838 * Added SilcIDListData structure and added it to SilcClientEntry
2839 and SilcServerEntry as their first field in the structure. This
2840 way we can explicitly cast the ID entries to the SilcIDListData
2841 structure and get common data for the entries. In past, we had
2842 to first check what type of connection it is and then cast it to
2843 correct ID entry type. Now, we can directly cast the opaque
2844 pointer to the SilcIDListData (no matter what ID entry it actually
2845 is) and get the data needed.
2847 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2849 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2850 in some circumstances even if threre were timeout tasks, though not
2851 IO tasks, but tasks anyway. Now fixed.
2853 * Defined SilcServerConnection structure to hold connection specific
2854 stuff about directly connected servers and routers. The definition
2855 is currently in silcd/server_internal.h. I thought about having
2856 a bit more important role fro this struct but for now it is used
2857 only when connecting to other server (or router actually).
2859 * Added connecting retry support in server when connecting to
2860 router(s). The retry feature implement exponential backoff
2861 algorithm. Also, added SilcServerParams structure to hold default
2862 parameters for server. For now, it include these retry settings
2863 and are hard coded. After server is moded to be as Silc Server
2864 Library this structure will be more important.
2866 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2868 * Changed client librarys channel->clients table to SilcList and
2869 changed code accordingly.
2871 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2873 * Changed client's channel table to SilcList and changed code
2874 accordingly. Also changed SilcChannelClientEntry to include back-
2875 pointer to the channel so that client entry can use that structure
2876 as list as well and we have fast cross-reference to the channel.
2877 This change dramatically decreased the complexity of channel
2878 handling with client entry and vice versa (removed one extra
2879 loop when searching for channel entry from many functions).
2881 * Changed server->sim from table to SilcDList and changed code
2884 * NAMES command can now be used from user interface. It will show
2885 the user list on the channel, neatly.
2887 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2888 Code now saves realname of the user if it becomes available.
2890 * Renamed configure.in to configure.in.pre and made ./prepare
2891 script to automatically add correct version string to
2892 configure.in which it creates from configure.in.pre.
2894 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2896 * NAMES command reply now shows users mode with the nickname when
2899 * Moved silc_client_ch[u]mode[_char] functions from
2900 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2901 place sucks, they are utility functions and should be in some
2904 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2906 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2909 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2913 * Added TRQ (efficient deque and list library) into lib/trq. This is
2914 a very good list library that is currently used in the SILC. Defined
2915 SilcList API over the library because I didn't like the API very
2916 much. See lib/trq/silclist.h for the API and examples of how to
2917 use the API. Fixed various places in the code to use the new
2918 SilcList API. The SilcList is meant for lists that has a structure
2919 already defined as a list. It is not suitable to add just some
2920 context to the list (in TRQ, the context is the list actually).
2922 So, I defined SilcDList that can be used for the purpose where
2923 predefined list structure does not exit. This can be used as
2924 such list. Now some context just can be added to the SilcDList.
2925 Currently this list is not used in the SILC just yet, though there
2926 are a lot places where this can replace dynamically allocated
2927 tables and I will fix these places, later, to use SilcDList.
2928 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2929 and use TRQ internally).
2931 Also fixed some annoying warning messages that the original TRQ
2932 code generated. Also minor changes to TRQ's Makefile.in.
2934 * Added support for querying by Client ID to both WHOIS and
2935 IDENTIFY commands into server, as required by the protocol.
2937 * Removed method function pointers from SilcBuffer structure. They
2938 weren't used to anything and just increased the context size for
2939 no good reason. This change also made silc_buffer_alloc and
2940 silc_buffer_free functions inline functions.
2942 * Disabled command flooding detection support until it's fixed so
2943 that it accepts commands in but does not execute them more than once
2946 * Added silc_net_localhost(), to return local hostname, into
2947 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2948 that must be initialized before calling silc_client_init.
2950 * Added new function: silc_server_send_notify_on_channels to send
2951 notify messages to all channels client has joined. It is assured
2952 that the message is sent only once per client.
2954 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2955 lib/silcutil/silcutil.[ch] as silc_format function. The new
2956 function is generic and is used by server as well, not only by
2957 the logging routines.
2959 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2960 the provided version string was not acceptable. Added new function:
2961 silc_ske_check_version into lib/silcske/silcske.h. The function
2962 must be implemented by the application (client or server) and it
2963 does not reside in the SKE library. The function checks the version
2964 string remote end sent.
2966 * Added back pointers (to opaque context and to SilcSocketConnection)
2967 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2969 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2970 duplicate packet context structure.
2972 * Changed `notify' client operation to send same arguments as client
2973 receives from server except for ID's. ID's are mapped to correct
2974 ID entry and that is returned. Also, if channel entry is not sent
2975 by server but the notify is for channel the channel entry is sent
2976 to application (otherwise application doesn't know that it is for
2977 channel (library gets it from packet's Destination ID)).
2979 * Added silc_client_remove_from_channels into client library to
2980 remove a client from all channels it has joined to. Used when
2981 received SIGNOFF notify from server. Added also new function
2982 silc_client_replace_from_channels to replace old ID entry with
2983 new ID entry on all channels. Used when received NICK_CHANGE
2986 * Fixed ID Cache list handling in silc_idlist_get_client in
2987 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
2988 to get (or query) client by ID.
2990 * Updated TODO list.
2992 * Added connection authentication status message defined by the
2993 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
2994 support for these into the code in client and server side.
2996 * Added generic function silc_client_send_command to send any command
2997 with variable argument list. Application should use this function
2998 to send commands if the command functions provided by the library
2999 does not suite for the application's user interface needs.
3001 * Added new `failure' client operation. Application is notified about
3002 received failure packet if client is executing a protocol. In this
3003 case the protocol's execution has failed.
3005 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3006 is required by the protocol.
3008 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3009 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3012 * Added status flag to SilcSKE object to indicate realtime status
3013 of the SKE protocol.
3015 * Application receives now exactly same command reply arguments as
3016 the library receives from server. However, if ID is received the
3017 corresponding ID entry is returned to the application (eg. Client
3018 ID is mapped to correct SilcClientEntry entry and that is returned).
3019 Changed command_reply client operation due to this change.
3021 * Changed all ID's in commands and in command replys as ID Payloads.
3022 Change affected both client and server side codes.
3024 All ID's sent in SILC network (with execption of ID's in SILC
3025 Packet header) are sent in ID Payload to support variable length
3028 * Server now notifies nick changes and notifies all clients on
3029 the channels about the new nickname (about the new Client ID,
3032 * Implemented CMODE command to change channel modes. Supports all
3033 channel modes defined by the protocol specs except ban and invite
3034 lists. (Also, private channel key mode is supported but support for
3035 setting private channel key in client is missing, thus, this mode
3036 has no effect on client side (except that server requires that the
3037 client uses private channel key and normal channel traffic does not
3040 Also, invite mode works per se, but INVITE command does not work
3041 yet correctly, so you can set channel as invite only channel but
3042 inviting clients to the channel does not work (it is yet to be
3043 thought what's the best way to do it).
3045 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3046 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3047 Implemented CUMODE command to change user's mode on the channel.
3048 Supports all modes defined by the protocol specs.
3050 * Added NAMES command reply to return users modes on the channel.
3052 * Removed unnecessary and slow ciphers from lib/silccrypt.
3054 * Set SO_KEEPALIVE option to connection sockets by default.
3056 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3058 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3059 redefined the Notify Payload into protocol specs.
3061 * Added silc_id_payload_parse_id to get ID directly from raw
3064 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3066 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3067 accept searching by Client ID as well.
3069 * Added support for LEAVE and SIGNOFF notify types in client library.
3071 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3072 to parse ID Payload from raw data.
3074 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3076 * Added flags parameter into silc_ske_assemble_security_properties
3077 function in lib/silcske/silcske.[ch].
3079 * Changed notify client operation to fit better for notify messages
3080 sent by server. The notify payload received from server is now
3081 passed to the application (after parsing it to SilcNotifyPayload).
3082 It is application's responsibility to retrieve the arguments
3083 from the payload and show the message the way it wants. The message
3084 sent by server is implementation specific.
3086 * Changed public keys to comply with the protocol specification.
3087 Old public keys are not supported anymore and are not compatible.
3089 * Removed nickname from Channel Payload as the latest draft removed
3090 it. The client must resolve the nickname from the NAMES command
3091 reply received when it joined the channel.
3093 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3095 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3097 * Fixed some errors in protocol specification drafts.
3099 * Created lib/silccore/silcnotify.c to implement Notify Payload
3100 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3101 generic payloads described by protocol specifications. The file
3102 includes implementations for ID Payload and Argument Payload.
3104 * Changed Command Payload implementation to use the new Argument
3105 Payload. Changed command_xxxx_payload to command_payload_xxxx
3106 to comply with SILC coding conventions.
3108 * Added suppport for Argument Payload handling in Notify Payload
3109 implementation as protocol requires it. Added the new support
3110 into server and client lib as well.
3112 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3114 * Added support for multiple nicknames on same channel. [n] is
3115 added locally to the nickname if there are more than one same
3116 nicknames on the channel.
3118 * Server now sends all nicknames that matched WHOIS request.
3119 Client also shows the list received from server.
3121 * Added TOPIC command to client side. User can now set and show
3122 current topic on channel.
3124 * Added MOTD command to client and server. Also, server sends the
3125 motd when client connects to the server.
3127 * Changed version strings to comply ISO 8601.
3129 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3131 * Fixed protocol error handling in client library. It should now
3132 cope even if the SKE fails for some reason.
3134 * Made new protocol specification drafts for submitting to IETF.
3136 * Implemented TOPIC command to server in silcd/command.c.
3138 * Added two new notify types into lib/silccore/silcnotify.h:
3139 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3140 notify nickname change and topic setting/change on a channel.
3142 * API change of command_reply operation in client library. The
3143 application gets now the status type received from server as well.
3145 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3147 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3149 * Cras fixed and optimized the packet handling even further and
3150 it should work now. Minor change to the prototype of function
3151 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3153 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3155 * Added new function into lib/silcutil/silcschedule.[ch]:
3156 silc_schedule_with_fd to select() a specified fd. The function
3157 returns after timeout expires or data arrives or goes. The
3158 function is used by packet routines to wait that all data is
3159 received from network.
3161 * Fixed data reading from network in lib/silccore/silcpacket.c.
3162 The code now assures that all data is read from the fd and then
3163 continues packet processing. This was a bug fix since the code
3164 used to drop some data in some circumstances.
3166 * Added new function into lib/silcclient/client.[ch]:
3167 silc_client_start_key_exchange to start key exchange after
3168 connection has been established to server. The code internally
3169 now uses this funtion but its main purpose was to provide it
3170 for applications that perform their own connecting. After
3171 application has created a connection it merely calls this
3172 function to start the key exchange between client and server.
3173 The library takes care of everything else after that.
3175 Updated also lib/silcclient/README to explain the usage of
3178 * Do not send to application information that connection has
3179 been established. Application gets notified it by connect
3182 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3184 * Applied cras's patch to add silc_schedule_one function. The
3185 function runs scheduler once and returns.
3187 * Fixed the scheduler after cras messed it up. The timeout
3188 handling works now as it's supposed to work.
3190 * Added into lib/silccore/ silcnotify.h to include notify
3191 message types support. Changed silc_server_send_notify*
3192 functions, in server.[ch], to support those new notify types.
3193 Added the support for the notify types into client library,
3194 as well. Added new notify client operation into ops.h in
3197 * Changed silc_server_packet_send_to_channel to send normal
3198 packets instead of just channel message packets. The function
3199 is now used to send the notify packets to channels. It is not
3200 used to send channel message packets anymore, as server never
3203 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3204 va_arg()s as it seems to require it nowadays. I guess, if SILC
3205 is compiled with older va_arg() the new code should work anyway.
3207 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3209 * Splitted core library. Core library (lib/silccore) includes
3210 now only SILC protocol specific core (and common) components.
3211 Created new utility library (lib/silcutil) that includes more
3212 generic purpose stuff. The stuff for util library was taken
3213 from the old core library. This was minor and easy split.
3215 * Created SILC Client Library (lib/silcclient) that includes
3216 implementation of the SILC client without user interface. This
3217 was major move from silc/ directory. The code has been changed
3218 so that it is transparent towards the user interface. The
3219 silc/ directory includes now the same user interface as before
3220 and it uses the new client library. Read lib/silcclient/README.
3221 Basicly, the client library performs everything else related
3222 to SILC except user interface handling. Also, configuration
3223 files are considered to be part of user interface and library
3224 does not handle them.
3226 This change also changed a lot of structures, function naming etc.
3227 Most important change was that SilcClientWindow object was
3228 renamed to SilcClientConnection in the client library. Created
3229 also new file lib/silcclient/ops.h. Also added new files
3230 silc/local_command.[ch] and silc/client_ops.[ch].
3232 All these changes were made to make it easier for user interface
3233 designers to create what ever user interface for the SILC client
3236 It is also expected that the server will be moved to lib
3237 directory as well and SILC Server Library will be created;
3238 sometimes in the future.
3240 * Removed Local commands from lib/silccore/silccommand.h as
3241 they are application specific and new client library does not
3242 handle any of those anymore.
3244 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3245 old client implementation in silc/.
3247 * Added support for callback functions in SILC_LOG_* macros.
3248 Application can now set its own callbacks that will be called
3249 instead of using the default functions that will always print
3250 the debug messages to stderr (or stdout). Also, debugging can
3251 now be disabled by setting silc_debug to FALSE and re-enabled by
3252 setting it to TRUE. Note, that logging will still work even
3253 if debugging is disabled.
3255 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3256 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3257 silc_log_reset_debug_callbacks.
3259 * To enable debugging in silc client one must give now -d
3260 option on command line.
3262 * Changed silc_schedule_init to automatically allocate task queues
3263 if they are not allocated before calling it.
3265 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3267 * Added GMP 3.1 into math library.
3269 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3271 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3272 a channel in SILC network. The packet is used by servers and
3273 routers to notify other routers that user has left a channel.
3274 This little feature was missing until now. Added the feature
3275 to protocol specification as well.
3277 Added functions: silc_server_send_remove_channel_user and
3278 silc_server_remove_channel_user into server.[ch].
3280 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3281 lib/silccore/silcpacket.h. However, they are not implemented
3284 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3286 * Fixed joining to a channel and sending channel messages
3287 between server and router. The channel message sending should
3288 now work inside a cell.
3290 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3292 * Fixed the private message sending between server and router.
3293 The private message sending should now work inside a cell.
3295 * Added silc_server_replace_id into server.[ch] to replace
3296 existing ID in the SILC network.
3298 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3299 and silc_idlist_replace_server_id into idlist.[ch] in server.
3301 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3303 * Fixed the server to server connections. Server can again now
3304 connect to router. Router to router connections probably does
3307 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3309 * Added dynamic protocol registering support. Now protocols can
3310 registered and unregistered on the fly. Patch by cras.
3312 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3314 * Added lib/contrib directory to hold routines that some platforms
3315 don't have but are needed by SILC.
3317 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3318 into lin/contrib to provide getopt() and getopt_long() for
3319 those who don't have it.
3321 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3323 * Added AWAY command to client. When away message is set and
3324 client receives a private message packet the client automatically
3325 replies to the sender with the away message.
3327 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3328 bug seemed to be the cause of recent problems when compiling
3331 * Added version detection support to SKE protocol specification
3332 and added the new changes to the SKE implementation as well.
3333 There were other minor changes in the SKE protocol as well.
3335 Many changes in lib/silcske/silcske.[ch] and in
3336 lib/silcske/payload.[ch].
3338 * Added ^U functionality, clear input line. Patch from cras.
3340 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3342 * Mainly small bugfixes on core library. Fixed some debugging
3343 logging and buffer overflow in silclog.c.
3345 * Updated config.sub and config.guess on the distribution tree.
3347 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3349 * Added command lagging support in server. Client may execute
3350 commands now only once in two seconds.
3352 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3354 * Optimized packet reception. MAC computation and checking is now
3355 also more optimized. A lot previously duplicated code is now
3356 used as generic by both client and server.
3358 * Fixed key pair generation in clientutil.c
3360 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3362 * Added into lib/silccore/silcbufutil.[ch] new function;
3363 silc_buffer_realloc.
3365 * Moved generic packet sending/encryption functions to
3366 lib/silccore/silcpacket.[ch] from client and server. Some
3367 rewriting of the functions.
3369 * Moved all generic packet reception/decryption functions to
3370 lib/silccore/silcpacket.[ch] from client and server. The
3371 packet processing is now much cleaner in both client and server.
3372 These were major changes in both client and server.
3374 * Created many common functions in server to do packet sending.
3375 Previously code were duplicated a lot, this has been removed
3378 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3380 * Rewrote major parts of the ID cache system. Don't know
3381 whether it is better now or not but at least the API is more
3384 * Major rewrite on ID cache stuff on client because of the ID
3385 cache API changes. Added idlist.c to client.
3387 * Also major rewrite on ID cache stuff on server as well.
3388 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3389 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3390 in hand, instead they are all put into the ID cache system now.
3391 All server_idlist_* routines uses ID cache now instead of
3392 traversing its own lists (those lists does not exist anymore).
3393 SilcIDList though still exists. Also, SilcXXXEntry's are
3396 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3398 * Finally made the SKE implementation compliant to the protocol
3399 specification. All mp integers are now binary encoded as
3400 opposed being HEX encoded.
3402 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3405 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3406 functions: silc_[encode/decode]_pem. Also added function
3407 silc_encode_pem_file to PEM encode with newlines ('\n') for
3410 * SILC public keys are now encoded either PEM or binary. Same
3411 option is for private keys as well. By default private keys
3412 are binary encoded and public keys PEM encoded. Silly HEX
3413 encoding were removed.
3415 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3416 function to create fingerprints.
3418 * Fixed a bug in SHA1; does not change the original data anymore.
3420 * Partly implemented INFO command on client and server side.
3421 Fixed CLEAR command. Changes to SERVER command; show current
3422 server(s) when giving command without arguments. Added
3423 VERSION command to client.
3425 * Added check to server that unregistered connections cannot
3426 execute commands (unless it is specificly allowed).
3428 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3430 * Fixed screen refresh.
3432 * Fixed channel joining bug from client. On some circumstances
3433 client tried to join to a channel it had already joined.
3435 * Added public key verification process into client's protocol.c.
3436 The client now verifies the public key from user and saves
3437 it into ~./silc/serverkeys/ directory.
3439 Added into: clientutil.[ch]: silc_client_verify_server_key.
3441 * Changed SKE protocol's silc_ske_initiator_finish function
3442 to accept callback function that verifies the received public
3443 key. Removed old silc_ske_verify_public_key function.
3445 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3447 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3448 silc_pkcs_private_key[_data]_set.
3450 * Made the password and public authentication more cleaner in
3451 server's protocol.c.
3453 * Removed historic and obsolete protocol `channel_auth' from
3454 both client and server.
3456 * Removed wrong way of sending command status messages from
3457 server to client in server's command.c. The old way violated
3458 protocol specification.
3460 Changes to silccore/silccommand.[ch]: removed
3461 silc_command_encode_status_payload -> not needed anymore,
3462 changed silc_command_encode_payload_va to accept extra
3463 argument on variable argument list. The argument type must
3464 now be provided to the function. Also, added new function:
3465 silc_command_encode_reply_payload_va which is same as
3466 normal command_encode_payload_va except command status type
3467 is provided as extra argument.
3469 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3471 * Added ~./silc directory handling. The directory includes the
3472 public and private keys for the client.
3474 Added silc_client_check_silc_dir, silc_client_create_identifier
3475 and silc_client_load_keys.
3477 * Implemented SILC protocol compliant public key. Added public
3478 and private key saving to and loading from files.
3480 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3481 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3482 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3483 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3484 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3486 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3487 silc_pkcs_load_[public/private]_key.
3489 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3491 * Added silc_server_get_route (route.[ch]) to get connection
3492 data for the fastest route for given ID.
3494 * Implemented INVITE command on client and server. The command
3495 were re-defined in the SILC Protocol Specification and the
3496 implementation now complies with the specification.
3498 * Implemented PING command on client and server.
3500 * Implemented NAMES command on client and server. The server side
3501 supports currently only normal server not router server yet.
3502 Some changes to NAMES definition in SILC protocol specification.
3504 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3506 * Implemented LEAVE command on client and server.
3508 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3509 again. This change was made to the protocol as well. Server
3510 should not violate the protocol specification anymore.
3512 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3514 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3515 was tested. SOCKS4 was not but should work anyway.
