[PATCH 0/6] virtio_net: use common code for virtio_net_hdr and skb GSO conversion
Hi,
This patches introduce virtio_net_hdr_{from,to}_skb functions for
conversion of GSO information between skb and virtio_net_hdr.
Mike Rapoport (6):
virtio_net: add _UAPI prefix to virtio_net header guards
virtio_net: introduce virtio_net_hdr_{from,to}_skb
macvtap: use common code for virtio_net_hdr and skb GSO conversion

[PATCH AUTOSEL 5.6 06/17] net: check untrusted gso_size at kernel entry
...nput:
a packet with gso size exceeding len.
These packets are dropped in tcp_gso_segment and udp[46]_ufo_fragment.
But they may affect gso size calculations earlier in the path.
Now that we have thlen as of commit 9274124f023b ("net: stricter
validation of untrusted gso packets"), check gso_size at entry too.
