This change will allow us to run SELinux in a container with
BTRFS back end. We continue to work on fixing the kernel/BTRFS
but this change will allow SELinux Security separation on BTRFS.
It basically relabels the content on container creation.
Just relabling -init directory in BTRFS use case. Everything looks like it
works. I don't believe tar/achive stores the SELinux labels, so we are good
as far as docker commit.
Tested Speed on startup with BTRFS on top of loopback directory. BTRFS
not on loopback should get even better perfomance on startup time. The
more inodes inside of the container image will increase the relabel time.
This patch will give people who care more about security the option of
runnin BTRFS with SELinux. Those who don't want to take the slow down
can disable SELinux either in individual containers or for all containers
by continuing to disable SELinux in the daemon.
Without relabel:
> time docker run --security-opt label:disable fedora echo test
test
real 0m0.918s
user 0m0.009s
sys 0m0.026s
With Relabel
test

Provide a command line option dm.use_deferred_deletion to enable deferred
device deletion feature. By default feature will be turned off.
Not sure if there is much value in deferred deletion being turned on
without deferred removal being turned on. So for now, this feature can
be enabled only if deferred removal is on.
