Yes, I also found this issue and have the same patch in my pipeline...

There are two other issues with the fib_rules_tests. The first is the test
didn't check the nfail and will always return 0. I will post the fix later.

An other issue is The IPv4 rule 'from iif' check test failed while IPv6
passed. I haven't found out the reason yet.

# ip -netns testns rule add from 192.51.100.3 iif dummy0 table 100
# ip -netns testns route get 192.51.100.2 from 192.51.100.3 iif dummy0
RTNETLINK answers: No route to host

    TEST: rule4 check: from 192.51.100.3 iif dummy0           [FAIL]

# ip -netns testns -6 rule add from 2001:db8:1::3 iif dummy0 table 100
# ip -netns testns -6 route get 2001:db8:1::2 from 2001:db8:1::3 iif dummy0
2001:db8:1::2 via 2001:db8:1::2 dev dummy0 table 100 metric 1024 iif dummy0 pref medium

    TEST: rule6 check: from 2001:db8:1::3 iif dummy0          [ OK ]
