patch 'cfgfile: fix section count with no name' has been queued to stable release 23.11.6

[Shani Peretz]

Hi,

FYI, your patch has been queued to stable release 23.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/26/25. 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/shanipr/dpdk-stable

This queued commit can be viewed at:
https://github.com/shanipr/dpdk-stable/commit/37cc8cb726f37d9ca35142d10f54f324c9b0e4b2

Thanks.

Shani

Subject: [PATCH] cfgfile: fix section count with no name

[ upstream commit 02bce2f1e938b409bb6f85391510a2a33ecc1443 ]

Passing a NULL to strncmp is incorrect.

 + ------------------------------------------------------- +
 + Test Suite : Test Cfgfile Unit Test Suite
 + ------------------------------------------------------- +
../lib/cfgfile/rte_cfgfile.c:475:7: runtime error: null pointer passed as
	argument 2, which is declared to never be null

On the other hand, it seems the intent was to count all sections, so
skip the whole loop and section name comparisons.

Fixes: c54e7234bc9e ("test/cfgfile: add basic unit tests")
