Subject: patch 'net/hns3: fix crash from secondary process' has been queued to stable release 21.11.2
Date: Fri, 24 Jun 2022 16:01:38 +0100	[thread overview]
Message-ID: <20220624150148.1855580-30-ktraynor@redhat.com> (raw)

Hi,

FYI, your patch has been queued to stable release 21.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/22. 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

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/35582af08c0c141db6b5ddb4abcc893b7643fc98

Thanks.

Kevin

Subject: [PATCH] net/hns3: fix crash from secondary process

[ upstream commit 8ba42ce98dd45958354817c340796f3ce6496410 ]

If a hns3 device in the secondary process is attached to do probing
operation, 'rx_queues' and 'tx_queues' in dev->data are null in
eth_dev_fp_ops_setup when calling rte_eth_dev_probing_finish. The primary
process calls dev_start to re-setup their fp_ops. But the secondary process
can't call dev_start and has no chance to do it. If the application sends
and receives packets at this time, a segfault will occur. So this patch
uses the MP communication of the PMD to update the fp_ops of the device in
the secondary process.

Fixes: 96c33cfb06cf ("net/hns3: fix Rx/Tx functions update")
