[PATCH] selinux: Disable automatic labeling of new inodes when no policy is loaded
This patch disables the automatic labeling of new inodes on disk when no policy is loaded. Discussion is here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=180296 In short, we're changing the behavior so that when no policy is loaded, SELinux does not label files at all. Currently it does add an 'unlabeled' label in this case, which we've found causes problems later. SELinux always maintains a safe internal label if there is none, so with this patch, we just stick with that and wait until a policy is loaded before adding a persistent label on disk. The effect is simply that if you boot with SELinux enabled but no policy loaded and create a file in that state, SELinux won't try to set a security extended attribute on the new inode on the disk. This is the only sane behavior for SELinux in that state, as it cannot determine the right label to assign in the absence of a policy. That state usually doesn't occur, but the rawhide installer seemed to be misbehaving temporarily so it happened to show up on a test install.
