Make sure that security_locked_down() is checked last so that a bogus denial is not reported by SELinux when (ia->ia_valid & (ATTR_MODE | ATTR_UID | ATTR_GID)) is zero.Why would this be "bogus"?I presume selinux is logging a denial ... but we don't then actually deny the operation.
That would be nice to note here...
