linux: Implement tmpfile with O_TMPFILE (BZ#21530)
This patch adds O_TMPFILE support to tmpfile on Linux. This is similar to the previous suggestion by Andreas Schwab [1] with the difference the file descriptor creation is parameterized to compartmentalize Linux only open flags (O_TMPFILE) on sysdeps. Checked on x86_64-linux-gnu. Adhemerval Zanella <adhemerval.zanella@linaro.org> Andreas Schwab <schwab@suse.de> [BZ #21530] * include/stdio.h (__gen_tempfd): New function. * stdio-common/Makefile (routines): Add gentempfd. * stdio-common/gentempfd.c: New file. * sysdeps/unix/sysv/linux/gentempfd.c: Likewise. * stdio-common/tmpfile.c (tmpfile): First try to use a system specific unnamed file first.
