Bug description:
== SRU Justification ==
This commit is being requested in Bionic and linux-azure by Microsoft. It
has
already been applied to Bionic. It is being requested in Artful, so it makes
it's way into linux-azure through the re-base process.
This fix is required if a large number of records are injected into a pool,
which can cause the kvp daemon to crash.
This commit has been cc'd to upstream stable. However, it has not yet been
applied
to Artful, since upstream 4.13 is EOL.
== Fix ==
297d6b6e56c2 ("hv: kvp: Avoid reading past allocated blocks from KVP file")
== Regression Potential ==
Low. This patch has also been sent to upstream stable, so it has had
additional upstream
review.
== 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.
