Hi,

FYI, your patch has been queued to stable release 22.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/24. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/6a3050209505a7b82cc8f20591a54fab5cd86bc2

Thanks.

Luca Boccassi

Subject: [PATCH] bus/vdev: revert fix devargs in secondary process

[ upstream commit 22ce39b3aadb109cbefabb91aad44c94e8c2a5e6 ]

The ASan tool detected a memory leak in the vdev driver
alloc_devargs. The previous commit was that when inserting
a vdev device, the primary process alloc devargs and the
secondary process looks for devargs. This causes the
device to not be created if the secondary process does
not initialise the vdev device. And, this is not the
root cause.

Therefore the following commit was reverted accordingly.

After restoring this commit, the memory leak still exists.

Fixes: 6666628362c9 ("bus/vdev: fix devargs in secondary process")
