6d08eb1614 Fix sparse warnings and add an extra sprinkling of const.
This is more or less the equivalent of Sven-Haegar Koch's fixes in the 1.1
branch.

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 -

It can either be set globally in tinc.conf, or per-node in host config files.

edebf579f2 Use the TCP socket infrastructure for control sockets.
The control socket code was completely different from how meta connections are
handled, resulting in lots of extra code to handle requests.  Also, not every
operating system has UNIX sockets, so we have to resort to another type of
sockets or pipes for those anyway.  To reduce code duplication and make control
sockets work the same on all platforms, we now just connect to the TCP port
where tincd is already listening on.

To authenticate, the program that wants to control a running tinc daemon must
send the contents of a cookie file. The cookie is a random 256 bits number that
is regenerated every time tincd starts. The cookie file should only be readable
by the same user that can start a tincd.

Instead of the binary-ish protocol previously used, we now use an ASCII
protocol similar to that of the meta connections, but this can still change.

5cbddc68ba Use uint32_t instead of long int for connection options.
Options should have a fixed width anyway, but this also fixes a possible MinGW
compiler bug where %lx tries to print a 64 bit value, even though a long int is
only 32 bits.

9b394bc887 Ensure tinc compiles with gcc -std=c99.
We use a lot of C99 features already, but also some extensions which are not in
the standard.

551cd19406 Move RSA key generation into the wrappers. 2008-12-14 12:47:26 +00:00
Guus Sliepen
046158a216 Use the crypto wrappers again instead of calling OpenSSL directly.
This theoretically allows other cryptographic libraries to be used,
and it improves the readability of the code.

6eaefb4dbc Dump through control socket
Note this removes SIGUSR1, SIGUSR2, and the graph dumping config option.
It seems cleaner to do everything through the control socket.

40731d030f Temporarily revert to old crypto code
(The new code is still segfaulting for me, and I'd like to proceed with other
work.)

This largely rolls back to the revision 1545 state of the existing code
(new crypto layer is still there with no callers), though I reintroduced
the segfault fix of revision 1562.

1b8f891836 Finish crypto wrapping. Also provide wrappers for OpenSSL.
Disable libgcrypt by default. Since it doesn't support the OFB cipher mode,
we can't use it in a backwards compatible way.

38c25d62c2 Convert to libevent.
This is a quick initial conversion that doesn't yet show much advantage:
- We roll our own timeouts.
- We roll our own signal handling.
- We build up the meta connection fd events on each loop rather than
  on state changes.
