udp: fix receiving fraglist GSO packets

Browse source

[ Upstream commit b128ed5ab2 ]

When assembling fraglist GSO packets, udp4_gro_complete does not set
skb->csum_start, which makes the extra validation in __udp_gso_segment fail.

Fixes: 89add40066 ("net: drop bad gso csum_start and offset in virtio_net_hdr")
