From 7c5e8d212d7d81991a580e7de3904ea213d9a852 Mon Sep 17 00:00:00 2001 From: Muhammad Usama Anjum Date: Fri, 9 Aug 2024 12:56:42 +0500 Subject: selftests: memfd_secret: don't build memfd_secret test on unsupported arches [1] mentions that memfd_secret is only supported on arm64, riscv, x86 and x86_64 for now. It doesn't support other architectures. I found the build error on arm and decided to send the fix as it was creating noise on KernelCI: memfd_secret.c: In function 'memfd_secret': memfd_secret.c:42:24: error: '__NR_memfd_secret' undeclared (first use in this function); did you mean 'memfd_secret'? 42 | return syscall(__NR_memfd_secret, flags); | ^~~~~~~~~~~~~~~~~ | memfd_secret Hence I'm adding condition that memfd_secret should only be compiled on supported architectures. Also check in run_vmtests script if memfd_secret binary is present before executing it.
