Title:
virtio-net ignores the absence of the VIRTIO_NET_F_CTRL_VQ feature bit
Status in QEMU:
Expired
Bug description:
When negotiating virtio-net feature bits, the device ignores the
absence of the VIRTIO_NET_F_CTRL_VQ bit in driver feature bits and
provides three virtqueues, including the control virtqueue, even
though the driver is expecting only the receive and transmit
virtqueues. Looking into the source code, it appears it always assumes
the presence of the control virtqueue, violating thus the VIRTIO
version 1.0 specification.
