CHROMIUM: device_jail: detach all interfaces
permission_broker iterates through every available interface of
the USB device to detach drivers. We should do the same thing
here.
BUG=chromium:644338
TEST=On kevin:
kill permission_broker, set up device_jail_utility server.
Use lsusb -t to find a device with an attached kernel driver,
i.e. btusb, add a jail for it
In python:
>>> f = open("/dev/jailed-189-XXX", "rb")
Choose "detach" in the server. Check syslog, lsusb -t again
to make sure the driver was detached.
In python:
>>> f.close()
Ensure the driver is reattached. (If using btusb you can also
check visually that the bluetooth menu disables itself when
you detach the driver, and re-enables itself when you attach
it again.)
