This is because of the default 45 seconds timeout in kselftest framework. A quick test shows these tests will take about: xfrm_policy.sh - 2m19.690s pmtu.sh - 3m6.832s udpgso_bench.sh - 0m57.985s [Fix] * b881d089c7c9c7 ("selftests/net: bump timeout to 5 minutes") We have commit 852c8cbf34d3b3 ("selftests/kselftest/runner.sh: Add 45 second timeout per test") for default timeout added since Bionic. However there is a SAUCE patch ("UBUNTU: SAUCE: selftests/net -- disable timeout") to disable timeout for the net test in newer releases. I think we can leave it as-is for the moment unless some test is hanging too long because of that. Therefore Only Bionic needs this patch, the patch can be applied with some context adjustment. [Test] With this patch applied, these tests should have a chance to finish. [Where problems could occur] The fix is just for testing tool, no actual impact to real kernel functions. If this 5 minutes timeout is not enough, we might still seeing this kind of failures in the test report. [Original Bug Report] These 3 tests will fail with timeout when running the whole "net" test in ubuntu_kernel_selftests: * not ok 12 selftests: net: xfrm_policy.sh # TIMEOUT * not ok 16 selftests: net: pmtu.sh # TIMEOUT * not ok 19 selftests: net: udpgso_bench.sh # TIMEOUT However they will pass if you run them manually. So there must be some test in net that will cause this. From the test result it looks like the test was executed in the following sequence: ok 1 selftests: net: reuseport_bpf ok 2 selftests: net: reuseport_bpf_cpu ok 3 selftests: net: reuseport_bpf_numa ok 4 selftests: net: reuseport_dualstack # Successok 5 selftests: net: reuseaddr_conflict ok 6 selftests: net: tls ok 7 selftests: net: run_netsocktests ok 8 selftests: net: run_afpackettests ok 9 selftests: net: test_bpf.sh ok 10 selftests: net: netdevice.sh ok 11 selftests: net: rtnetlink.sh not ok 12 selftests: net: xfrm_policy.sh # TIMEOUT not ok 13 selftests: net: test_blackhole_dev.sh # exit=1 ok 14 selftests: net: fib_tests.sh ok 15 selftests: net: fib-onlink-tests.sh not ok 16 selftests: net: pmtu.sh # TIMEOUT ok 17 selftests: net: udpgso.sh not ok 18 selftests: net: ip_defrag.sh # exit=255 not ok 19 selftests: net: udpgso_bench.sh # TIMEOUT ok 20 selftests: net: fib_rule_tests.sh not ok 21 selftests: net: msg_zerocopy.sh # exit=1 ok 22 selftests: net: psock_snd.sh ok 23 selftests: net: udpgro_bench.sh ok 24 selftests: net: udpgro.sh ok 25 selftests: net: test_vxlan_under_vrf.sh ok 26 selftests: net: reuseport_addr_any.sh ok 27 selftests: net: test_vxlan_fdb_changelink.sh ok 28 selftests: net: so_txtime.sh ok 29 selftests: net: ipv6_flowlabel.sh ok 30 selftests: net: tcp_fastopen_backup_key.sh ProblemType: Bug DistroRelease: Ubuntu 19.10 Package: linux-image-5.3.0-1009-aws 5.3.0-1009.10 ProcVersionSignature: User Name 5.3.0-1009.10-aws 5.3.13 Uname: Linux 5.3.0-1009-aws aarch64 ApportVersion: 2.20.11-0ubuntu8.3 Architecture: arm64 Date: Wed Dec 11 06:42:39 2019 Ec2AMI: ami-047cec24582f6ae0d Ec2AMIManifest: (unknown) Ec2AvailabilityZone: us-west-2c Ec2InstanceType: a1.large Ec2Kernel: unavailable Ec2Ramdisk: unavailable SourcePackage: linux-aws UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1856010/+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
