I tried on my test machine, it looks the test is executed in init netns. I modified my patch by setting the net.mptcp.enabled to 1 without setting it back. You can find the value is changed after testing. # cat /proc/sys/net/mptcp/enabled 0 # ./test_progs -t mptcp #127/1 mptcp/base:OK #127 mptcp:OK Summary: 1/1 PASSED, 0 SKIPPED, 0 FAILED # cat /proc/sys/net/mptcp/enabled 1 Thanks Hangbin
