Hi, executing the seccomp_bpf testsuite with 32 bit userland (both s390 and x86) doesn't work because there's no compat_ioctl handler defined. Is that something that is supposed to work? Disclaimer: I don't know enough about seccomp to judge whether there would be some adjustments required in the compat ioctl handler. Just setting it to seccomp_notify_ioctl() makes the testsuite pass, but i'm not sure whether that's correct.
