Subject: [PATCH v2 0/2] net: prevent infinite loop caused by incorrect proto from virtio_net_hdr_set_proto

Here is v2 of the patches that prevent an infinite loop for gso packets
with a protocol from virtio net hdr that doesn't match the protocol in
the packet. Note that packets coming from a device without
header_ops->parse_protocol being implemented will not be caught by
the check in virtio_net_hdr_to_skb, but the infinite loop will still
be prevented by the check in the gso layer.

Balazs Nemeth (2):
  net: check if protocol extracted by virtio_net_hdr_set_proto is
    correct
  net: avoid infinite loop in mpls_gso_segment when mpls_hlen == 0
