[PATCH net-next] vhost_net: add a missing error return
From: Dan Carpenter <hidden>
Date: 2018-09-20 10:01:59
Also in:
kernel-janitors, kvm, virtualization
Subsystem:
the rest, virtio host (vhost) · Maintainers:
Linus Torvalds, "Michael S. Tsirkin", Jason Wang
We accidentally left out this error return so it leads to some use after
free bugs later on.
Fixes: 0a0be13b8fe2 ("vhost_net: batch submitting XDP buffers to underlayer sockets")
