[dpdk-stable] patch 'net/bonding: fix OOB access in other aggregator modes' has been queued to LTS release 18.11.6

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/10/19. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/47233bb7f2eb73cb82d08ede312469951a06dcb8

Thanks.

Kevin.

Subject: [PATCH] net/bonding: fix OOB access in other aggregator modes

[ upstream commit dfbc596c2e1418780f77954e1859ffec9aebfe4f ]

slave aggregator_port_id is in [0, RTE_MAX_ETHPORTS-1] range.
If RTE_MAX_ETHPORTS is > 8, we can hit out of bound accesses on
agg_bandwidth[] and agg_count[] arrays.

Fixes: 6d72657ce379 ("net/bonding: add other aggregator modes")
