Used your attached config and booted a kernel with the HEAD you mentioned: $ uname -r 5.2.0-rc5-01201-gd5382fef70ce $ ./fib_tests.sh ... Tests passed: 150 Tests failed: 0 Also tested: net, net-next, master All look fine. Plus, I'm pretty sure I ran this test before initially submitting the patchset. Can you reliably reproduce these failures on current kernels or is this some random failure you noticed while testing the mentioned commit? Thanks
