Greeting,
FYI, we noticed the following commit (built with gcc-11):
commit: 0e4d354762cefd3e16b4cff8988ff276e45effc4 ("net-next: Fix IP_UNICAST_IF option behavior for connected sockets")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: kernel-selftests
version: kernel-selftests-x86_64-700a8991-1_20220823
with following parameters:
group: net
test: fcnal-test.sh
atomic_test: ipv6_udp
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 (Skylake) 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

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.

Richard:
Don't recall a followup on this report. Can you take a look? These tests
were added by you after your change for IP_UNICAST_IF.
