Zeeb from comment #9) > The /dev/mem ones could probably be PCIOCBARMMAP if that could be/is locked down enough? Yes, it seems possible. > But I assume all the checks needed are in place (now) somewhere for the IO ioctl? I'm not sure if I understand the question. The new ioctl limits accesses to the specified BAR and verifies that the accesses is within bounds. The /dev/io interface permits access to any system I/O port. -- You are receiving this mail because: You are the assignee for the bug.
