Hi All: This patch tries to validate the used buffer length in the virtio core. This help to eliminate the unexpected result caused by buggy or mailicous devices. For the drivers that can do the validation itself, they can ask the virtio core to suppress the check. Changes since V4: - Fix the out of date description in the commit log Changes since V3: - Initialize the buflen to zero when the validation is done by the driver.
