Description Dmitry V. Levin 2019-12-13 23:11:29 UTC 
This bug report is cloned from https://pagure.io/fedora-infrastructure/issue/8449

Please fix s390x builders regression.
These builders used to work OK when I submitted strace 5.3 to Fedora at the end of September (see https://koji.fedoraproject.org/koji/buildinfo?buildID=1390111).
At the end of November, however, when I submitted strace 5.4,
the strace test suite complained that on s390x out-of-range syscalls do not generate ptrace syscall stops any longer.
See strace build log for details
(e.g. https://koji.fedoraproject.org/koji/taskinfo?taskID=39456442).

This looks like a seccomp+kernel issue specific to s390x.

This regression blocks build of strace package.
Comment 1 Dmitry V. Levin 2020-01-08 19:58:41 UTC 
Apparently, arch/s390/include/asm/syscall.h:syscall_get_nr() returns 0 for out-of-range syscall numbers.
This bug is exposed via PTRACE_GET_SYSCALL_INFO interface and breaks strace.
Comment 2 Hanns-Joachim Uhl 2020-06-24 08:35:51 UTC 
Hello Dmitry,
... with Fedora 32 now generally available I am closing this Fedora bugzilla as CURRENTRELEASE ...
... please reopen if required ...
Thanks for your support.
