[PATCH 09/10] vsock/virtio: fix src/dst cid format
From: "Michael S. Tsirkin" <mst@redhat.com>
Date: 2016-12-06 15:41:22
Also in:
kvm, lkml, stable
Subsystem:
networking [general], the rest, virtio and vhost vsock driver, virtio core, vm sockets (af_vsock) · Maintainers:

These fields are 64 bit, using le32_to_cpu and friends on these will not do the right thing. Fix this up. Cc: stable@vger.kernel.org Signed-off-by: Michael S. Tsirkin <mst@redhat.com> --- net/vmw_vsock/virtio_transport_common.c | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-)
