294ce72441 Use libevent to handle HUP signal. 2007-05-17 21:34:58 +00:00

4d0621b1f3 Use libevent to dump graphs when necessary.
event_add() can be called repeatedly, the second and later calls are ignored if
the event hasn't been removed yet.

0f6f54ff8a Use a separate event structure to handle meta data writes.

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.

834290b00f A couple missed tevent things.
(Sorry; had a couple changes queued.)
2007-02-27 01:30:57 +00:00
Scott Lamb
6362b12df7 Rename "event_t" to "tevent_t", along with associated functions.
This relieves some confusion and problems during the libevent transition.
In particular, "event_add" was defined by both.
(The 't' stands for 'timeout', 'tinc', 'temporary', or some such.)

5214ece030 Fix generic BSD tun device to write only the actual packet length.
Due to a copy&paste bug, it tried to write a packet with the maximum size.
This was not a problem until the maximum size was increased to support VLANs.

40f02ff8ee Tapreader socket should be bound to localhost only. 2007-01-04 15:28:36 +00:00
Guus Sliepen
03f3fc01e8 Use a ringbuffer in shared memory to transfer packets from the tapreader thread to the main thread.
It's a wonder it ever worked before. The socket that is created is not of a
datagram type, therefore packet boundaries were not preserved, which becomes
a problem as soon as the TAP-Win32 device receives packets in fast succession.

855806b2f7 Do a simple test for linux/if_tun.h instead of no test at all. 2006-12-16 16:53:58 +00:00
Guus Sliepen
0322c0883b Remove the test for linux/if_tun.h.
It has been available for years on any decent Linux distribution.
Although linux/if_tun.h is now required to compile tinc,
you can still run it on systems which only support Ethertap.

134dc8995b memcpy() addresses from packet headers before calling the lookup functions.
