Bug Description

[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.

    selftests/seccomp: Catch garbage on SECCOMP_IOCTL_NOTIF_RECV

    BugLink: https://bugs.launchpad.net/bugs/1860799

    commit e4ab5ccc357b978999328fadae164e098c26fa40 upstream.

    This adds logic to the user_notification_basic test to set a member
    of struct seccomp_notif to an invalid value to ensure that the kernel
    returns EINVAL if any of the struct seccomp_notif members are set to
    invalid values.

    Signed-off-by: Sargun Dhillon <email address hidden>
    Suggested-by: Christian Brauner <email address hidden>

The test will pass with this patch reverted.

However as this patch ensures we have a correct return value EINVAL, so it means this might be a kernel issue.
