patch 'net/af_packet: fix crash in secondary process' has been queued to stable release 24.11.4

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/05/25. 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/c55c49157434d006eeaea92ed92e472efef067b0

Thanks.

Kevin

Subject: [PATCH] net/af_packet: fix crash in secondary process

[ upstream commit d57124f60ef60b24cd39e895cf6d211b93b897ae ]

dumpcap crashes when trying to capture from af_packet devices. This is
caused by allocating interface name with
strdup (i.e. malloc). Interface name is not accessible from secondary
process and causes segmentation fault. Use rte_malloc instead of
strdup to fix the issue.

Bugzilla ID: 1786
Fixes: 1b93c2aa81b4 ("net/af_packet: add interface name to internals")
