82f00ea07b Use PRF. 2011-07-03 15:59:49 +02:00
Guus Sliepen
feb3f22fff Add PRF to derive key material from the ECDH shared secret. 
It is modelled after the pseudorandom function from RFC4346 (TLS 1.1), the only
significant change is the use of SHA512 and Whirlpool instead of MD5 and SHA1.

8dfa072733 Support ECDH key exchange. 
REQ_KEY requests have an extra field indicating key exchange version.
If it is present and > 0, the sender supports ECDH. If the receiver also
does, then it will generate a new keypair and sends the public key in a
ANS_KEY request with "ECDH:" prefixed. The ans_key_h() function will
compute the shared secret, which, at the moment,is used as is to set the
cipher and HMAC keys. However, this must be changed to use a proper KDF.
In the future, the ECDH key exchange must also be signed.

8c953b1bfe Don't react to escape character in tincctl top. 
Not only the ESC key generates an escape character, but many other keys
do as well, such as arrow keys.

ab4d289faf Make pid files backwards compatible and add address of listening socket. 
The pid is now written first, so that a version 1.0.x tincd can be used to stop
a running version 1.1 tincd.  Getsockname() is used to determine the address of
the first listening socket, so that tincctl can connect to the local tincd even
if AddressFamily = ipv6, or if BindToAddress or BindToInterface is used.

Guus Sliepen
1fe8ba2f06 Delete mtuevent if it is not used. 
Keeping it around prevents ans_key_h() from restarting PMTU discovery.

4b3fd94b1c Improved --logfile option. 
Instead of UNIX time, the log messages now start with the time in RFC3339
format, which human-readable and still easy for the computer to parse and sort.
The HUP signal will also cause the log file to be closed and reopened, which is
useful when log rotation is used. If there is an error while opening the log
file, this is logged to stderr.

50af33d01f Nearly tickless tinc. 
Use pselect instead of select in main_loop (if available). This lets
tincd sleeps as long as there is nothing to do.

8b3cc695b5 Don't ignore SIGCHLD, system() needs it. 
But we do ignore SIGPIPE, and tinc 1.0.x signals that are no longer used
(SIGUSR1 and SIGUSR2), since the default handler of these signals is to
terminate tincd immediately.

5989a29d7b Fix format strings for Windows. 
Windows doesn't like %zd, so cast (s)size_t to int. Also, some shorts were
incorrectly printed with %d instead of %hd.

a8f0d21330 More stable sorting in tincctl top. 
Although we use qsort(), which is not guaranteed to be stable, resorting the
previously sorted array is more stable than recreating and resorting the array
each time.
