Subject[PATCH net 0/2] vsock/virtio: fix null-pointer dereference and related precautions
Date
This series mainly solves a possible null-pointer dereference in
virtio_transport_recv_listen() introduced with the multi-transport
support [PATCH 1].

PATCH 2 adds a WARN_ON check for the same potential issue
and a returned error in the virtio_transport_send_pkt_info() function
to avoid crashing the kernel.

vsock/virtio: add WARN_ON check on virtio_transport_get_ops()
