[SRU][Artful][Bionic][PATCH 0/2] Fixed for LP:1734327

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1734327

== SRU Justification ==
The following commit introduced a regression identified in bug 1734327:
ac8f82a0b6d9 ("UBUNTU: SAUCE: LSM stacking: LSM: Infrastructure management of the remaining blobs")

The regression causes a kernel panic to occur after multiple TCP connection 
creations/closures to the localhost.  The bug was found using STAF RPC calls, 
but is easily reproducible with SSH.    

A revert of commit ac8f82a0b6d9 is needed to resolve this bug.  However, commit 4ae2508f0bed
also needs to be reverted because it depend on commit ac8f82a0b6d9.

== Fix ==
Revert 4ae2508f0bed ("UBUNTU: SAUCE: LSM stacking: add stacking support to apparmor network hooks")
Revert ac8f82a0b6d9 ("UBUNTU: SAUCE: LSM stacking: LSM: Infrastructure management of the remaining blobs")

== Test Case ==
A test kernel was built with these two commits reverted and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
