From 9493892021eac4edf1776d945bcdd3f7a96f6978 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 18 Jul 2019 15:16:20 -0400 Subject: refactor all stat functions in terms of fstatat equivalent logic for fstat+O_PATH fallback and direct use of stat/lstat syscalls where appropriate is kept, now in the fstatat function. this change both improves functionality (now, fstatat forms equivalent to fstat/lstat/stat will work even on kernels too old to have the at functions) and localizes direct interfacing with the kernel stat structure to one file. --- src/stat/fstat.c | 13 ++----------- 1 file changed, 2 insertions(+), 11 deletions(-) (limited to 'src/stat/fstat.c') diff --git a/src/stat/fstat.c b/src/stat/fstat.c index 4f13f4f0..d2a828f3 100644 --- a/src/stat/fstat.c +++ b/src/stat/fstat.c @@ -1,3 +1,4 @@ +#define _BSD_SOURCE #include #include #include @@ -5,17 +6,7 @@ int fstat(int fd, struct stat *st) { - int ret = __syscall(SYS_fstat, fd, st); - if (ret != -EBADF || __syscall(SYS_fcntl, fd, F_GETFD) < 0) - return __syscall_ret(ret); - - char buf[15+3*sizeof(int)]; - __procfdname(buf, fd); -#ifdef SYS_stat - return syscall(SYS_stat, buf, st); -#else - return syscall(SYS_fstatat, AT_FDCWD, buf, st, 0); -#endif + return fstatat(fd, "", st, AT_EMPTY_PATH); } weak_alias(fstat, fstat64); -- cgit v1.2.1
