Now that glibc 2.11 offers mkostemps, we should too. Any objections to this
patch series?
Eric Blake (3):
tempname: resync from glibc
This patch conflicts with coreutils' local override of tempname.c, so I'm also
working on a coreutils followup patch to fix things once coreutils imports the
latest gnulib, as well as to make mktemp(1) smarter.
mkstemps, mkostemps: new modules
Pretty much straight out of glibc.
stdlib-safer: wrap all mkstemp variants
Makes "stdlib--.h" recognize the 2 new variants, as well as mkostemp.

Subject: [PATCH 1/3] tempname: resync from glibc
* lib/tempname.c (__gen_tempname): Add suffixlen argument. Use
same values for __GT_FILE as glibc. Abort even when assertions
are disabled.
* lib/tempname.h (GT_FILE): Use glibc __GT_FILE, if available, and
match its value otherwise. Allow idempotent inclusion.
* lib/mkdtemp.c (mkdtemp): Adjust caller.
* lib/mkostemp.c (mkostemp): Likewise.
* lib/mkstemp.c (mkstemp): Likewise.
* lib/tmpfile.c (tmpfile): Likewise.
* NEWS: Document this.

From: Eric Blake <address@hidden>
Date: Mon, 2 Nov 2009 16:11:18 -0700
Subject: [PATCH 3/3] stdlib-safer: wrap all mkstemp variants
* modules/mkostemp (configure.ac): Set witness.
* modules/mkostemps (configure.ac): Likewise.
* modules/mkstemps (configure.ac): Likewise.
* lib/stdlib-safer.h (mkostemp_safer, mkostemps_safer)
(mkstemps_safer): Wrap more functions.
* lib/stdlib--.h (mkostemp, mkostemps, mkstemps): Default the
wrapping.
* lib/mkstemp-safer.c (mkostemp_safer, mkostemps_safer)
(mkstemps_safer): Implement the wrappers.
