Use devname() if available to support devfs cloning on BSD.

Some BSD flavors allow opening /dev/tun and/or /dev/tap, which automatically
create a new tun or tap interface with an unused number. To find out which
number the interface got, you have to call devname() on the device file
that was opened.

The semantics are different from the way Linux's /dev/tun works though.
In particular, after closing the device, the interface will continue to exist.
Restarting tincd would cause the old interface to stay around, and a new
one to be created. One could add a tinc-down script with the following line:

ifconfig $INTERFACE destroy

But that is still no guarantee that restarting tinc will give you the same
interface. So the default tun and tap device will stay /dev/tun0 and /dev/tap0
for all BSD flavors to avoid surprises for existing users.

Configure minimum reconnect timeouts.

Enable the configuration of minimum reconnect timeout via a
configuration directive "MinTimeout". This functionality is missing in
the default tinc stable distribution. The minimum timeout is, in code,
set to 0 seconds. This patch makes it configurable.

You might ask yourself why is that needed at all ?

Well, we've been using tinc with success for quite some time in a cross DC
setup. Tinc is used to create a virtual network switch and to connect our
distributed database nodes into a virtual local network. Our database nodes
exchange information, synchronize and do failover over the created
tinc-backed network.

Every now and then, when a node has a physical networking issue and is
unreachable by some or all neighboring nodes, tinc will relay traffic over
reachable neighboring nodes and thus save our cluster. But, sometimes,
especially when BGP route changes take place, minor outages of physical
connectivity towards some nodes may cause tinc to become as reliable as
packet-loss is :).

Tinc is fast, it can and does re-establish a lost connection in a jiffy,
but it cannot detect the reason for the loss of the connection. A
re-established connection might last for a few seconds (ping timeout) to
get lost again just because the packet loss is huge at that time. Then it
reconnects again and the story repeats itself.

This process keeps repeating until the physical network stabilizes. Packet
loss on a physical link means disaster in a database replication scenario.
In such cases it is better for tinc to remain disconnected from the
unreachable/destabilized nodes for some time and relay traffic over the
reachable (unaffected) nodes then to use an unreliable route.

This patch enables us to slow down the re-connection process and eliminate
application level issues we had.

Guus Sliepen [Tue, 6 May 2014 10:39:59 +0000 (12:39 +0200)]
Nexthop calculation should always use the shortest path.

When tinc runs the graph algorithms and updates the nexthop and via pointers,
it uses a breadth-first search, but it can sometimes revisit nodes that have
already been visited if the previous path is marked as being indirect, and
there is a longer path that is "direct". The via pointer should be updated in
this case, because this points to the closest hop to the destination that can
be reached directly. However, the nexthop pointer should not be updated.

This fixes a bug where there could potentially be a routing loop if a node in
the graph has an edge with the indirect flag set, and some other edge without
that flag, the indirect edge is part of the minimum spanning tree, and a
broadcast packet is being sent.

ciphertext data into the connection. If an attacker also identifies packets
with a plaintext it can guess (e.g. small packets every 1s are probably
pings), the attacker can xor the ciphertext to mangle the packet to
arbitrary plaintext. Although this type of attack is rarely seen in the
wild, it is generally considered technically viable.
