From b5beb07ad32ab533027aa988d96a44965ec116f7 Mon Sep 17 00:00:00 2001 From: John Johansen Date: Fri, 9 Feb 2018 04:57:39 -0800 Subject: apparmor: fix resource audit messages when auditing peer 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.
