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.
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.
Hello Dmitry, ... with Fedora 32 now generally available I am closing this Fedora bugzilla as CURRENTRELEASE ... ... please reopen if required ... Thanks for your support.
