Hi,
FYI, your patch has been queued to stable release 24.11.3
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/23/25. 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/a9eabc9d05e721bef57dfe08a160dd5de37c262b
Thanks.
Kevin

Subject: [PATCH] examples/ipsec-secgw: fix crash with IPv6
[ upstream commit d03869e8e9c7c46bf7637d221ca6921516764109 ]
While running ipsec-secgw application if IPv6 rules are not
configured in IPsec configuration, LPM look up fails and
destination port is updated as BAD_PORT. During process_packet
ethernet_hdr is updated resulting in crash due to out of bound.
This patch fixes the same.
Fixes: 6eb3ba03995c ("examples/ipsec-secgw: support poll mode NEON LPM lookup")
