601f3b2dd7 Clean up digests when freeing a connection_t. 2011-06-06 20:12:33 +02:00

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.

25b467638a Drop the GNU malloc.c, realloc.c, and xmalloc.c. 
We live in the 21st century, and we require C99 semantics, so we do not need to
work around buggy libcs. The xmalloc() and related functions are now static
inline functions.

e452a933f9 Simplify signal handling. 
We don't override any signal handlers anymore except those for SIGPIPE and
SIGCHLD. Fatal signals (SIGSEGV, SIGBUS etc.) will terminate tincd and
optionally dump core.  The previous behaviour was to terminate gracefully and
try to restart, but that usually failed and made any core dump useless.

5bc957074a Allow tincctl to connect to something besides localhost. 
This would allow tincctl to connect to a remote tincd, or to a local tincd that
isn't listening on localhost, for example if it is using the BindToInterface or
BindToAddress options.

453c44e7b2 Add the ability to dump all traffic going through route() over a control connection. 
One can get the packet stream in pcap format, which can be decoded using
tcpdump, for example:

tincctl -n <netname> pcap | tcpdump -r -

931e30f91a Always compact the buffer if it has reached MAXBUFSIZE. 2011-05-22 13:24:01 +02:00

90c7fafe59 Compact input buffer before trying to read instead of after. 
Also log an error when the input buffer contains more than MAXBUFSIZE bytes
already, instead of silently claiming the other side closed the connection.
