Also, I think you will want to have the global namespace always use the original security labels. If accessing an object from outside the container, the original global policy should always apply. Really, this needs to be an invariant property. I'd suggest implementing an orthogonal 2nd set of security labels which are only ever used within the container. > To implement this would require a revision on the selinux labels xattrs > so that they can be marked as being part of a container...

It'll be interesting to see. -- James Morris <jmorris@xxxxxxxxx> _______________________________________________ Selinux mailing list Selinux@xxxxxxxxxxxxx To unsubscribe, send email to Selinux-leave@xxxxxxxxxxxxx.
