patch 'raw/ifpga: fix free function mismatch in interrupt config' has been queued to stable release 22.11.7

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 22.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/25/24. 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/8a8601623860ef67574e8bce04429c48a9978abf

Thanks.

Luca Boccassi

Subject: [PATCH] raw/ifpga: fix free function mismatch in interrupt config
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[ upstream commit d891a597895bb65db42404440660f82092780750 ]

The raw ifpga driver redefines malloc to be opae_malloc
and free to be opae_free; which is a bad idea.

This leads to case where interrupt efd array is allocated with calloc()
and then passed to rte_free.
The workaround is to allocate the array with rte_calloc() instead.

Fixes: d61138d4f0e2 ("drivers: remove direct access to interrupt handle")
