Greeting,

FYI, we noticed the following commit (built with gcc-9):

commit: 9b17afb2c88bbadcc15b96f0275c426ae3d89a33 ("netfilter: nft_meta: track register operations")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

in testcase: kernel-selftests
version: kernel-selftests-x86_64-db530529-1_20220124
with following parameters:

	group: netfilter
	ucode: 0xe2

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) i7-6770HQ CPU @ 2.60GHz with 32G memory

caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):




If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang@...el.com>


# selftests: netfilter: nft_meta.sh
# FAIL: icurrentyearcounter, want "packets 2", got
# table inet filter {
# 	counter icurrentyearcounter {
# 		packets 0 bytes 0
# 	}
# }
not ok 11 selftests: netfilter: nft_meta.sh # exit=1



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.
