Subject: [dpdk-stable] patch 'net/ring: fix device pointer on allocation' has been queued to LTS release 18.11.9
Date: Fri,  5 Jun 2020 19:24:40 +0100
Message-ID: <20200605182525.22483-43-ktraynor@redhat.com> (raw)
In-Reply-To: <20200605182525.22483-1-ktraynor@redhat.com>

Hi,

FYI, your patch has been queued to LTS release 18.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/10/20. 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/160d1b6410cd4db1ec84dba0038f377605741c4f

Thanks.

Kevin.

Subject: [PATCH] net/ring: fix device pointer on allocation

[ upstream commit 8459f5ab32211fb10bbfe388fa0e017475d8507c ]

When a net_ring device is allocated, its device pointer is not set
before calling rte_eth_dev_probing_finish, which is incorrect.

The following:
  commit 96cb19521147 ("net/ring: use EAL APIs in PMD specific API")
  commit a6992e961050 ("net/ring: set ethernet device field")

already fixed the same issue in 17.08, which was fine at the time.
Adding the hook rte_eth_dev_probing_finish() however created this bug,
as the eth_dev exposed when this hook is executed is expected to be
complete.

Remove the prior attempts to fix the issue in rte_pmd_ring_probe() and
write the pointer properly in do_eth_dev_ring_create().

Fixes: fbe90cdd776c ("ethdev: add probing finish function")
