Instead of seperately checking for various conditions,
which don't actually guarantee that the hoodfile can be
fetched in a certain way (e.g. internet is available but
keyxchange is down), the already built in return value of
the hoodfile gathering functions is utilized.
This change slightly changes the behaviour of nodes in
certian edge cases:
- If no hoodfile could be fetched from keyxchange, the
next delivery method (getGatewayHoodfile) is used
- If the gateway is unable to deliver a hoodfile, nodes
now behave like the gateway is unreachable, instead of
continuing to use old hoodfiles
These behaviour changes should be an improvement over the
previous behaviour:
- VPN nodes don't disconnect and break the whole network
if the keyxchange is unreachable, but instead try to
fetch the hoodfile from the gateway
- Instead of checking for batman gateway announcements,
which are completely unrelated to hoodfile delivery using
fe80::1, the actual status of the hoodfile download is
utilized. This has two effects:
- hoodfile delivery using fe80::1 works even if batmans
gateway selection isn't used at all
- if the batman gateway selection is active, but fe80::1
hoodfile delivery is broken in the hood, the nodes disconnect
from the hood and try to gather their hoodfile from nerby
nodes. Previously they continued to use the old hoodfile.
This should make misconfigured gateways more apparent.
