So for the fstatat() function, make sure we convert it from a +64bit kstat to a 32bit stat. + +Along these lines, we need to restore the __xstat32_conv() function. + +Reported-by: Timo Teräs <timo.teras@iki.fi> +Signed-off-by: Mike Frysinger <vapier@gentoo.org> +Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com> +--- + libc/sysdeps/linux/common/fstatat.c | 9 +++++++-- + libc/sysdeps/linux/common/fstatat64.c | 5 +++++ + libc/sysdeps/linux/common/xstatconv.c | 19 +++++++++++++++++++ + libc/sysdeps/linux/common/xstatconv.h | 1 + + 4 files changed, 32 insertions(+), 2 deletions(-) + +diff --git a/libc/sysdeps/linux/common/fstatat.c b/libc/sysdeps/linux/common/fstatat.c +index 149c189..33daa7c 100644 +--- a/libc/sysdeps/linux/common/fstatat.c ++++ b/libc/sysdeps/linux/common/fstatat.c +@@ -10,15 +10,20 @@ + #include <sys/stat.h> + #include "xstatconv.h" + ++/* 64bit ports tend to favor newfstatat() */ ++#ifdef __NR_newfstatat ++# define __NR_fstatat64 __NR_newfstatat ++#endif ++ + #ifdef __NR_fstatat64 + int fstatat(int fd, const char *file, struct stat *buf, int flag) + { + int ret; +- struct kernel_stat kbuf; ++ struct kernel_stat64 kbuf; + + ret = INLINE_SYSCALL(fstatat64, 4, fd, file, &kbuf, flag); + if (ret == 0) +- __xstat_conv(&kbuf, buf); ++ __xstat32_conv(&kbuf, buf); + + return ret; + } +diff --git a/libc/sysdeps/linux/common/fstatat64.c b/libc/sysdeps/linux/common/fstatat64.c +index 5ae1fad..95627af 100644 +--- a/libc/sysdeps/linux/common/fstatat64.c ++++ b/libc/sysdeps/linux/common/fstatat64.c +@@ -12,6 +12,11 @@ + + #ifdef __UCLIBC_HAS_LFS__ + ++/* 64bit ports tend to favor newfstatat() */ ++#ifdef __NR_newfstatat ++# define __NR_fstatat64 __NR_newfstatat ++#endif ++ + #ifdef __NR_fstatat64 + int fstatat64(int fd, const char *file, struct stat64 *buf, int flag) + { +diff --git a/libc/sysdeps/linux/common/xstatconv.c b/libc/sysdeps/linux/common/xstatconv.c +index e575b26..50455c6 100644 +--- a/libc/sysdeps/linux/common/xstatconv.c ++++ b/libc/sysdeps/linux/common/xstatconv.c +@@ -46,6 +46,25 @@ void attribute_hidden __xstat_conv(struct kernel_stat *kbuf, struct stat *buf) + buf->st_ctim = kbuf->st_ctim; + } + ++void __xstat32_conv(struct kernel_stat64 *kbuf, struct stat *buf) ++{ ++ /* Convert to current kernel version of `struct stat64'. */ ++ memset(buf, 0x00, sizeof(*buf)); ++ buf->st_dev = kbuf->st_dev; ++ buf->st_ino = kbuf->st_ino; ++ buf->st_mode = kbuf->st_mode; ++ buf->st_nlink = kbuf->st_nlink; ++ buf->st_uid = kbuf->st_uid; ++ buf->st_gid = kbuf->st_gid; ++ buf->st_rdev = kbuf->st_rdev; ++ buf->st_size = kbuf->st_size; ++ buf->st_blksize = kbuf->st_blksize; ++ buf->st_blocks = kbuf->st_blocks; ++ buf->st_atim = kbuf->st_atim; ++ buf->st_mtim = kbuf->st_mtim; ++ buf->st_ctim = kbuf->st_ctim; ++} ++ + #ifdef __UCLIBC_HAS_LFS__ + + void attribute_hidden __xstat64_conv(struct kernel_stat64 *kbuf, struct stat64 *buf) +diff --git a/libc/sysdeps/linux/common/xstatconv.h b/libc/sysdeps/linux/common/xstatconv.h +index 57c8bcb..7568da8 100644 +--- a/libc/sysdeps/linux/common/xstatconv.h ++++ b/libc/sysdeps/linux/common/xstatconv.h +@@ -26,6 +26,7 @@ + #include <bits/kernel_stat.h> + + extern void __xstat_conv(struct kernel_stat *kbuf, struct stat *buf) attribute_hidden; ++extern void __xstat32_conv(struct kernel_stat64 *kbuf, struct stat *buf) attribute_hidden; + #if defined __UCLIBC_HAS_LFS__ + extern void __xstat64_conv(struct kernel_stat64 *kbuf, struct stat64 *buf) attribute_hidden; + #endif +-- +1.6.6.1 + |
