[SRU][Xenial][PATCH 0/1] audit: stop an old auditd being starved out by a new auditd

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1633404

== SRU Justification ==
Nothing prevents a new auditd starting up and replacing a valid
audit_pid when an old auditd is still running, effectively starving out
the old auditd since audit_pid no longer points to the old valid
auditd.

This bug was fixed in v4.6-rc1 by commit 133e1e5acd4a63c4a0dcc413e90d5decdbce9c4a.  
This commit is needed in Trusty and Xenial.   This commit is a clean cherry
pick in Xenial, but it required some backporting for Trusty.  Because of this
the Xenial and Trusty SRU requests will be seperate.


== Fix ==
commit 133e1e5acd4a63c4a0dcc413e90d5decdbce9c4a

    audit: stop an old auditd being starved out by a new auditd


== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
