From 6bbfc5c09fc5b5e3d4a0cddbbd4e2e457767dae7 Mon Sep 17 00:00:00 2001 From: Mao Han Date: Mon, 26 Nov 2018 11:13:32 +0800 Subject: Add statx conditionals for wordsize-32 *xstat.c Linux kernel have remove stat64 family from default syscall set, new implementations with statx is needed when __ARCH_WANT_STAT64 is not define. This patch add conditionals for relevant functions, using statx system call to get information and then copy to the return buf, ref to include/linux/fs.h from linux kernel. * sysdeps/unix/sysv/linux/Makefile: Add statx_cp.c. * sysdeps/unix/sysv/linux/fxstat64.c: Add conditionals for kernel without stat64 system call support. * sysdeps/unix/sysv/linux/fxstatat64.c: Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/fxstat.c: Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/fxstatat.c: Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/lxstat.c: Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/lxstat64.c: Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/xstat.c: Likewise. * sysdeps/unix/sysv/linux/generic/wordsize-32/xstat64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/statx_cp.c: New file. * sysdeps/unix/sysv/linux/statx_cp.c: Likewise. * sysdeps/unix/sysv/linux/statx_cp.h: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/statx_cp.c: Likewise. --- sysdeps/unix/sysv/linux/statx_cp.c | 49 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 49 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/statx_cp.c (limited to 'sysdeps/unix/sysv/linux/statx_cp.c') diff --git a/sysdeps/unix/sysv/linux/statx_cp.c b/sysdeps/unix/sysv/linux/statx_cp.c new file mode 100644 index 0000000000..04a13fab85 --- /dev/null +++ b/sysdeps/unix/sysv/linux/statx_cp.c @@ -0,0 +1,49 @@ +/* Struct statx to stat/stat64 conversion for Linux. + Copyright (C) 2018 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.
