WARNING:at_net/netfilter/core.c:#__nf_unregister_net_hook
Greeting,
FYI, we noticed the following commit (built with gcc-9):
commit: 6069da443bf65f513bb507bb21e2f87cfb1ad0b6 ("netfilter: nf_tables: unregister flowtable hooks on netns exit")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: kernel-selftests
version: kernel-selftests-x86_64-4aeb6e60-1_20220324
with following parameters:
group: netfilter
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
caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):
If you fix the issue, kindly add following tag
