I cannot reproduce this unfortunately. For example, local_termination.sh gives me the following result with the exact patches that I submitted. Any idea on what might be the difference? root@localhost:~/ksft-net-drv# ./run_kselftest.sh -t net/forwarding:local_termination.sh [71318.022491] kselftest: Running tests in net/forwarding TAP version 13 1..1 #
