apparmor: fix resource audit messages when auditing peer
commit b5beb07ad32ab533027aa988d96a44965ec116f7 upstream. Resource auditing is using the peer field which is not available when the rlim data struct is used, because it is a different element of the same union. Accessing peer during resource auditing could cause garbage log entries or even oops the kernel. Move the rlim data block into the same struct as the peer field so they can be used together. CC: <stable@vger.kernel.org> Fixes: 86b92cb782b3 ("apparmor: move resource checks to using labels") Signed-off-by: John Johansen <john.johansen@canonical.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
