    GSO: Provide software checksum of tunneled UDP fragmentation offload · 22463876
    Alexander Duyck authored
    On reviewing the code I realized that GRE and UDP tunnels could cause a
    kernel panic if we used GSO to segment a large UDP frame that was sent
    through the tunnel with an outer checksum and hardware offloads were not
    In order to correct this we need to update the feature flags that are
    passed to the skb_segment function so that in the event of UDP
    fragmentation being requested for the inner header the segmentation
    function will correctly generate the checksum for the payload if we cannot
    segment the outer header.
