Hi, It's me again. Don't throw things at me, but it is the same old vanilla torvalds tree kernel 6.5-rc2 kselftest run, and after applying the patches I ran into the new problems: I have been free to add the timeout SIGTERM trap to the test, and this is the only change, save for the Ido's lib.sh patch (for filling the veth NETIFS array in default execution case). Here is the command output: # selftests: net/forwarding: gre_custom_multipath_hash.sh # TEST: ping [ OK ] # TEST: ping6 [ OK ] # INFO: Running IPv4 overlay custom multipath hash tests # TEST: Multipath hash field: Inner source IP (balanced) [ OK ] #

I have tried to reduce the complexity by adding: trap cleanup INT TERM EXIT to the tests that timed out. Kind regards, Mirsad
