[issue16946] subprocess: _close_open_fd_range_safe() does not set close-on-exec flag on Linux 2.6.23 if O_CLOEXEC is defined

2013-01-12 Thread STINNER Victor 

New submission from STINNER Victor:

The following extract of _close_open_fd_range_safe() is not correct:

#ifdef O_CLOEXEC
fd_dir_fd = open(FD_DIR, O_RDONLY | O_CLOEXEC, 0);
#else
fd_dir_fd = open(FD_DIR, O_RDONLY, 0);
#ifdef FD_CLOEXEC
{
int old = fcntl(fd_dir_fd, F_GETFD);
if (old != -1)
fcntl(fd_dir_fd, F_SETFD, old | FD_CLOEXEC);
}
#endif
#endif

On Linux older than 2.6.23, O_CLOEXEC may be defined by the glibc whereas the 
kernel does not support it. In this case, the flag is simply ignored and 
close-on-exec flag is not set on the file descriptor.
