Message

This series includes a bunch of fixes for SKB_GSO_FRAGLIST
packets, popped out while enabling the mentioned GRO type
in non trivial forwarding scenarios.

The last patch extends the existing UDP GRO self-tests to
cover the currently bugged cases.

Paolo Abeni (4):
  net: fix double-free on fraglist GSO skbs
  udp: fix out-of-bound at segmentation time
  udp: fix outer header csum for SKB_GSO_FRAGLIST over UDP tunnel
  selftests: more UDP GRO tests
