Wanted to get some EXPERT opinion on this...
I've noticed that the linux kernel allows anyone to freely request/release IRQ, DMA, and I/O. Is this a security hole, or am I missing something that only allows root to do these things?
I was considering giving each resource region a uid, with only root or the owner being allowed to change that region. Originally I was going to use the devname, but this is not secure enough, and things like the serial drivers might not like that.
Is it necessary to add anything for security? Or should the status quo be maintained?
