Instead of trying to fix our security drivers, we can use a simple trick to relabel paths in both namespace and the host. I mean, if we enter the namespace some paths are still shared with the host so any change done to them is visible from the host too. Therefore, we can just enter the namespace and call SetAllLabel()/RestoreAllLabel() from there. Yes, it has slight overhead because we have to fork in order to enter the namespace. But on the other hand, no complexity is added to our code. Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
