seccomp_bpf.c:1902:TRACE_syscall.syscall_faked:Expected 45000 (45000) ==
syscall(236) (18446744073709551615)
01:54:40 ERROR| [stderr] TRACE_syscall.syscall_faked: Test failed at step #11
This fails after the fix for LP: #1895132. However, this is not a
regression. s390x ptrace does not support changing the syscall return
code and the other way was not expected by strace (so tests for that one
were failing).
We have not been running this test on s390x since after 4.18. After an
effort to get that fixed on ppc64el (because it also has some different
behaviors, like only able to set syscall return code at exit time),
there was some restructure of the test.
Applying that patchset would allow us to get s390x test back to work on
4.15 kernels, and also start running it on 5.4 and later kernels.
Cascardo.
