Thanks for the fix! That looks correct to me. It seems the refactoring in 8014370f1257 ("apparmor: move path_link mediation to using labels") didn't take 8486adf0d755 ("apparmor: use designated initializers") into account. John, if this looks okay, can you Ack it for James to carry in security-next? -Kees -- Kees Cook Pixel Security
