True, Linux could do more to prevent this kind of abuse. In fact IIRC, if you enable secureboot, it does exactly that. A generic uio driver isn't a good interface because it relies on these sysfs files. We are luckly it doesn't work for VFs, I don't think we should do anything that relies on this interface in future applications. -- MST
