From a43e62dddcf51ec6578a90c5988a41e856b44b05 Mon Sep 17 00:00:00 2001 From: Mark Wielaard <mark@klomp.org> Date: Sat, 18 Nov 2023 21:17:02 +0100 Subject: [PATCH] Add fchmodat2 syscall on linux fchmodat2 is a new syscall on linux 6.6. It is a variant of fchmodat that takes an extra flags argument. https://bugs.kde.org/show_bug.cgi?id=477198 (cherry picked from commit 372d09fd9a8d76847c81092ebff71c80fd6c145d) --- NEWS | 1 + coregrind/m_syswrap/priv_syswrap-linux.h | 3 +++ coregrind/m_syswrap/syswrap-amd64-linux.c | 2 ++ coregrind/m_syswrap/syswrap-arm-linux.c | 2 ++ coregrind/m_syswrap/syswrap-arm64-linux.c | 2 ++ coregrind/m_syswrap/syswrap-linux.c | 11 +++++++++++ coregrind/m_syswrap/syswrap-mips32-linux.c | 2 ++ coregrind/m_syswrap/syswrap-mips64-linux.c | 1 + coregrind/m_syswrap/syswrap-nanomips-linux.c | 1 + coregrind/m_syswrap/syswrap-ppc32-linux.c | 2 ++ coregrind/m_syswrap/syswrap-ppc64-linux.c | 2 ++ coregrind/m_syswrap/syswrap-s390x-linux.c | 2 ++ coregrind/m_syswrap/syswrap-x86-linux.c | 2 ++ include/vki/vki-scnums-shared-linux.h | 2 ++ 14 files changed, 35 insertions(+) diff --git a/coregrind/m_syswrap/priv_syswrap-linux.h b/coregrind/m_syswrap/priv_syswrap-linux.h index 7c9decf5a..798c456c9 100644 --- a/coregrind/m_syswrap/priv_syswrap-linux.h +++ b/coregrind/m_syswrap/priv_syswrap-linux.h @@ -331,6 +331,9 @@ DECL_TEMPLATE(linux, sys_openat2); // Linux-specific (new in Linux 5.14) DECL_TEMPLATE(linux, sys_memfd_secret); +// Since Linux 6.6 +DECL_TEMPLATE(linux, sys_fchmodat2); + /* --------------------------------------------------------------------- Wrappers for sockets and ipc-ery.
