I've confirmed that if "ubuntu_cts_kernel" runs before this test, it will cause the test to fail. It will continue to fail between reboots of the virtual machine, too, so I suspect there's something persistent being added during the "ubuntu_cts_kernel" test that just isn't being cleaned up when it's done.
I disabled all of the tests that "ubuntu_cts_kernel" runs and started activating them one-by-one until it causes the ipv6 defrag test case to fail. It started failing when I activated the first one named: 'lp1262692' -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1826848 Title: ip_defrag.sh in net from ubuntu_kernel_selftests failed with 5.0.0 kernel Status in ubuntu-kernel-tests: Confirmed Status in linux package in Ubuntu: Confirmed Status in linux source package in Disco: In Progress Bug description: Test failed becuase: ./ip_defrag: sendto overlap: 1400: Operation not permitted selftests: net: ip_defrag.sh ======================================== ipv6 tx:17 gso:1 (fail) OK ipv4 defrag PASS seed = 1556203721 ipv4 defrag with overlaps PASS seed = 1556203722 ipv6 defrag seed = 1556203756 PASS ipv6 defrag with overlaps seed = 1556203756 ./ip_defrag: sendto overlap: 1400: Operation not permitted not ok 1..17 selftests: net: ip_defrag.sh [FAIL] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1826848/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
