From 8b9283dabd5ab3524c9a76fabbb379f950a86e6d Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Tue, 13 Dec 2016 16:50:06 -0200 Subject: Consolidate renameat Linux implementation This patch consolidates the Linux renameat implementation on sysdeps/unix/sysv/linux/renameat.c. The renameat syscall was deprecated at b0da6d44 for newer architectures, so using the auto-generation list may generate wrappers that returns ENOSYS. Current code try to use __NR_renameat and if it is not define it uses __NR_renameat2. Checked on x86_64 and aarch64. * sysdeps/unix/sysv/linux/renameat.c: New file. * sysdeps/unix/sysv/linux/syscalls.list: Remove renameat. --- sysdeps/unix/sysv/linux/renameat.c | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/renameat.c (limited to 'sysdeps/unix/sysv/linux/renameat.c') diff --git a/sysdeps/unix/sysv/linux/renameat.c b/sysdeps/unix/sysv/linux/renameat.c new file mode 100644 index 0000000000..ac52947995 --- /dev/null +++ b/sysdeps/unix/sysv/linux/renameat.c @@ -0,0 +1,32 @@ +/* Linux implementation for renameat function. + Copyright (C) 2016 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
