This change add more metrics around "meta" (non "message" type packets).
For lighthouse packets, we also record statistics around the specific
lighthouse meta type.
We don't keep statistics for the "message" type so that we don't slow
down the fast path (and you can just look at metrics on the tun
interface to find that information).
This change adds a new helper, `(*HostInfo).logger()`, that starts a new
logrus.Entry with `vpnIp` and `certName`. We don't use the helper inside
of handshake_ix though since the certificate has not been attached to
the HostInfo yet.
Fixes: #84
This change exposes the current constants we have defined for the handshake
manager as configuration options. This will allow us to test and tweak
with different intervals and wait rotations.
# Handshake Manger Settings
handshakes:
# Total time to try a handshake = sequence of `try_interval * retries`
# With 100ms interval and 20 retries it is 23.5 seconds
try_interval: 100ms
retries: 20
# wait_rotation is the number of handshake attempts to do before starting to try non-local IP addresses
wait_rotation: 5
