This series fixes a bypass of untrusted GSO flow dissection in
__virtio_net_hdr_to_skb() when VIRTIO_NET_HDR_F_NEEDS_CSUM is not set,
and adds a kselftest covering VLAN-tagged GSO packets without NEEDS_CSUM:

- Patch 1 fixes __skb_flow_dissect(), which computes key_control->thoff
  with min_t(u16, ...). This truncates skb->len and returns a bogus small
  transport offset when skb->len modulo 65536 is smaller than the
  transport offset. Offsets that do not fit in the u16 thoff now fail the
  dissection instead of being silently truncated.

[...]

You are awesome, thank you!
