** Description changed: [Impact] Running seccomp kernel selftests will fail. [Test case] Run linux/tools/testing/selftests/seccomp/seccomp_bpf. On failure: + seccomp_bpf.c:3149:global.user_notification_basic:Expected -1 (18446744073709551615) == ret (0) seccomp_bpf.c:3150:global.user_notification_basic:Expected EINVAL (22) == errno (0) global.user_notification_basic: Test failed at step #3 [ FAIL ] global.user_notification_basic On success: + [ RUN ] global.user_notification_basic + [ OK ] global.user_notification_basic + + [Regression potential] The test is checking that the given structure which the kernel will write to is all zeroes. It's doing it because it wants userspace to have the possibility in the future to give data there indicating support for an extension that might be developed in the future. As the test is there right now, not applying the breaking uABI fix might cause us to miss applications that would break in future kernels. As the backport for that is prone for more regression potential, we are deciding to revert the new test. - ====================================== Issue found on Oracle Bionic 5.0 (oracle : 5.0.0-1011.16 : amd64) [ RUN ] global.user_notification_basic seccomp_bpf.c:3149:global.user_notification_basic:Expected -1 (18446744073709551615) == ret (0) seccomp_bpf.c:3150:global.user_notification_basic:Expected EINVAL (22) == errno (0) global.user_notification_basic: Test failed at step #3 [ FAIL ] global.user_notification_basic This cannot be reproduced with the kselftest in older kernel, probably a test case issue.
