## Overview

In the Linux kernel, the following vulnerability has been resolved:

netfilter: flowtable: generalize pending status bit

Rename NF_FLOW_HW_PENDING to NF_FLOW_PENDING and use it to inhibit the
flowtable GC worker until pending hw offload work has been completed.

Apparently, nf_flow_offload_stats() can schedule work to retrieve stats
while the flow is being removed by GC.

And this bit can also be used in a follow up patch to disable GC until
the flow has been fully added in both directions.

Revert the reordering done in commit d644b23afe1e ("netfilter:
flowtable: publish HW_DEAD after worker is done") to prevent a race
between GC and hw offload handler.
