** 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:
+
+ [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)

-
- This cannot be reproduced with the kselftest in older kernel, probably a test
case issue.
