Greeting,

FYI, we noticed the following commit (built with gcc-11):

commit: 013ed7533966ffb31a234be3b2b402c2c78a024c ("selftests: Add duplicate config only for MD5 VRF tests")
https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable-rc.git linux-5.15.y

in testcase: kernel-selftests
version: kernel-selftests-x86_64-cebf67a3-1_20220613
with following parameters:

	group: net
	test: fcnal-test.sh
	atomic_test: ipv4_ping
	ucode: 0xec

test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt


on test machine: 8 threads Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz with 28G memory

# 
# SYSCTL: net.ipv4.raw_l3mdev_accept=1
# 
# TEST: ping out, VRF bind - ns-B IP                                            [ OK ]
...
# TEST: ping local, VRF bind - loopback                                         [ OK ]
# TEST: ping local, device bind - ns-A IP                                       [FAIL]
...



To reproduce:

        git clone https://github.com/intel/lkp-tests.git
        cd lkp-tests
        sudo bin/lkp install job.yaml           # job file is attached in this email
        bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
        sudo bin/lkp run generated-yaml-file

        # if come across any failure that blocks the test,
        # please remove ~/.lkp and /lkp dir to run from a clean state.
