SELinux: Unify context mount and genfs behavior
Context mounts and genfs labeled file systems behave differently with respect to setting file system labels. This patch brings genfs labeled file systems in line with context mounts in that setxattr calls to them should return EOPNOTSUPP and fscreate calls will be ignored. Signed-off-by: David P. Quigley <dpquigl@tycho.nsa.gov> Acked-by: Eric Paris <eparis@redhat.com> Signed-off-by: James Morris <jmorris@macbook.localdomain>
