    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.

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.
