Subject: patch 'net/netvsc: fix calculation of checksums based on mbuf flag' has been queued to stable release 21.11.2
Date: Tue, 10 May 2022 13:29:47 +0100
Message-ID: <20220510123010.159523-10-ktraynor@redhat.com> (raw)
In-Reply-To: <20220510123010.159523-1-ktraynor@redhat.com>

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 05/15/22. 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/550f0d82881008e4240fc1f9839e04283aae4b0b

Thanks.

Kevin

Subject: [PATCH] net/netvsc: fix calculation of checksums based on mbuf flag

[ upstream commit 559a1f2eeaaddccc83e1668a8ee375c34699e48b ]

The netvsc should use RTE_MBUF_F_TX_L4_MASK and check the masked value
to decide the correct way to calculate checksums.

Not checking for RTE_MBUF_F_TX_L4_MASK results in incorrect RNDIS
packets sent to VSP and incorrect checksums calculated by the VSP.

Fixes: 4e9c73e96e ("net/netvsc: add Hyper-V network device")
