====================
ICMP error handling for UDP tunnels
This series introduces ICMP error handling for UDP tunnels and
encapsulations and related selftests. We need to handle ICMP errors to
support PMTU discovery and route redirection -- this support is entirely
missing right now:
- patch 1/11 adds a socket lookup for UDP tunnels that use, by design,
the same destination port on both endpoints -- i.e. VXLAN and GENEVE
- patches 2/11 to 7/11 are specific to VxLAN and GENEVE
- patches 8/11 and 9/11 add infrastructure for lookup of encapsulations
where sent packets cannot be matched via receiving socket lookup, i.e.
FoU and GUE
- patches 10/11 and 11/11 are specific to FoU and GUE
v2: changes are listed in the single patches
