Hi,

FYI, your patch has been queued to stable release 24.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/21/26. 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/751d991b3ca34c18d9ef8446a1588a233929c878

Thanks.

Luca Boccassi

Subject: [PATCH] examples/vm_power: check truncation of socket path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[ upstream commit 90d45ee6021a163955a73c510375e9a2f2d0b1f6 ]

Without libbsd-devel strlcpy is defined as rte_strlcpy and a warning is
raised for format-truncation. Observed with gcc 15.2.1.

In function ‘rte_strlcpy’,
    inlined from ‘add_host_channels’ at
../examples/vm_power_manager/channel_manager.c:600:3:
../lib/eal/include/rte_string_fns.h:63:24:
warning: ‘%s’ directive output may be truncated writing up to
4095 bytes into a region of size 108 [-Wformat-truncation=]
63 |         return (size_t)snprintf(dst, size, "%s", src);
   |                        ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Check for truncation of socket_path[4096] into channel_path[108] to
remove warning.
