Given a hosed SELinux config in which a system never loads policy or disables SELinux we currently just return -EINVAL for anyone trying to read /proc/mounts. This is a configuration problem but we can certainly be more graceful. This patch just ignores -EINVAL when displaying LSM options and causes /proc/mounts display everything else it can. If policy isn't loaded the obviously there are no options, so we aren't really loosing any information here. This is safe as the only other return of EINVAL comes from security_sid_to_context_core() in the case of an invalid sid. Even if a FS was mounted with a now invalidated context that sid should have been remapped to unlabeled and so we won't hit the EINVAL and will work like we should. (yes, I tested to make sure it worked like I thought) Signed-off-by: Eric Paris <eparis@redhat.com> Tested-by: Marc Dionne <marc.c.dionne@gmail.com> Signed-off-by: James Morris <jmorris@namei.org> |
