[Bug 545795] Re: apparmor driver blocks access to hostdev and pcidev devices

[James Neave]

Hmm, it seems thats actually because usb2 is not supported in KVM?

I tried passing through the PCI card itself, but I'm back to permission
denied :(

device: 03:06.0: driver="pci-assign" host="03:06.0"
device: 03:06.1: driver="pci-assign" host="03:06.1"
device: 03:06.2: driver="pci-assign" host="03:06.2"
get_real_device: /sys/bus/pci/devices/0000:03:06.0/config: Permission denied
pci-assign: Error: Couldn't get real device (03:06.0)!
Error initializing device pci-assign

apparmour files contains:

  /sys/bus/usb/devices/ r,
  /sys/bus/usb/devices/** r,
  /sys/devices/**/usb[0-9]*/** r,
  /sys/bus/pci/devices/ r,
  /sys/bus/pci/devices/** r,
  /sys/devices/pci/** r,

  /dev/shm/ r,
  /dev/shm/pulse-shm* r,
  /dev/shm/pulse-shm* rwk,
  /dev/snd/* rw,
  /dev/bus/usb/** rw,
  /dev/** rwk,

Is there any way to get access to an apparmor trace file? See what it's
accessing?

Thanks,

James.
