3f5e3f5d06 libio: Implement internal function __libc_readline_unlocked
This is a variant of fgets which fails with ERANGE if the
buffer is too small, and the buffer length is given as an
argument of type size_t.

This function will be useful for implementing NSS file reading
operations.  Compared to a direct implementation using the public API,
it avoids an lseek system call in case the line terminator can be
found in the internal read buffer.

d6da5cb6a8 Add renameat2 function [BZ #17662]
The implementation falls back to renameat if renameat2 is not available
in the kernel (or in the kernel headers) and the flags argument is zero.
Without kernel support, a non-zero argument returns EINVAL, not ENOSYS.
This mirrors what the kernel does for invalid renameat2 flags.

9964a14579 Mechanically remove _IO_ name aliases for types and constants.
This patch mechanically removes all remaining uses, and the
definitions, of the following libio name aliases:

 name                         replaced with
 ----                         -------------
 _IO_FILE                     FILE
 _IO_fpos_t                   __fpos_t
 _IO_fpos64_t                 __fpos64_t
 _IO_size_t                   size_t
 _IO_ssize_t                  ssize_t or __ssize_t
 _IO_off_t                    off_t
 _IO_off64_t                  off64_t
 _IO_pid_t                    pid_t
 _IO_uid_t                    uid_t
 _IO_wint_t                   wint_t
 _IO_va_list                  va_list or __gnuc_va_list
 _IO_BUFSIZ                   BUFSIZ
 _IO_cookie_io_functions_t    cookie_io_functions_t
 __io_read_fn                 cookie_read_function_t
 __io_write_fn                cookie_write_function_t
 __io_seek_fn                 cookie_seek_function_t
 __io_close_fn                cookie_close_function_t

I used __fpos_t and __fpos64_t instead of fpos_t and fpos64_t because
the definitions of fpos_t and fpos64_t depend on the largefile mode.
I used __ssize_t and __gnuc_va_list in a handful of headers where
namespace cleanliness might be relevant even though they're
internal-use-only.  In all other cases, I used the public-namespace
name.

There are a tiny handful of places where I left a use of 'struct _IO_FILE'
alone, because it was being used together with 'struct _IO_FILE_plus'
or 'struct _IO_FILE_complete' in the same arithmetic expression.

Because this patch was almost entirely done with search and replace, I
may have introduced indentation botches.  I did proofread the diff,
but I may have missed something.

The ChangeLog below calls out all of the places where this was not a
pure search-and-replace change.

039c721a30 Fix -Os putc_unlocked, fputc_unlocked linknamespace, localplt issues (bug 15105, bug 19463).
Continuing the fixes for linknamespace and localplt test failures with
-Os that arise from functions not being inlined in that case, this
patch fixes such failures for putc_unlocked and fputc_unlocked.

libc_hidden_* are used for both functions, while namespace issues are
addressed by making putc_unlocked a weak alias of hidden
__putc_unlocked, which is called in the one place where namespace
issues arise (and defined as an inline function in include/stdio.h).

Tested for x86_64 (both without -Os to make sure that case continues
to work, and with -Os to make sure all the relevant linknamespace and
localplt test failures are resolved).  This completes fixing the -Os
linknamespace failures (at least for x86_64); localplt failures remain
after this patch.

30ac923dbe Fix -Os getc_unlocked linknamespace, localplt issues (bug 15105, bug 19463).
Continuing the fixes for linknamespace and localplt test failures with
-Os that arise from functions not being inlined in that case, this
patch fixes such failures for getc_unlocked.

__getc_unlocked already exists; this patch makes it explicitly hidden,
calls it where needed for namespace reasons, adds an inline function
for it when inline functions are used and adds libc_hidden_proto /
libc_hidden_weak for getc_unlocked.

Tested for x86_64 (both without -Os to make sure that case continues
to work, and with -Os to make sure all the relevant linknamespace and
localplt test failures are resolved).  Because of other such failures
that remain after this patch, neither of the bugs can yet be closed.

ec481ad81b Fix -Os ferror_unlocked linknamespace, localplt issues (bug 15105, bug 19463).
Continuing the fixes for linknamespace and localplt test failures with
-Os that arise from functions not being inlined in that case, this
patch fixes such failures for ferror_unlocked.

The usual approach is followed of adding __ferror_unlocked (inlined
when ferror_unlocked is), making calls use it when required for
namespace reasons (only one such call), and using libc_hidden_proto /
libc_hidden_weak for the ferror_unlocked weak alias when only localplt
but not namespace issues are involved.

Tested for x86_64 (both without -Os to make sure that case continues
to work, and with -Os to make sure all the relevant linknamespace and

499b315324 Use libc_hidden_* for fputs (bug 15105).
Among other localplt test failures when building with -Os, there are
libc.so PLT references for fputs.  fputs calls normally get redirected
to _IO_fputs by a macro in include/stdio.h (and _IO_fputs in turn uses
libc_hidden_proto), but GCC can convert an fprintf call with a
constant string argument into an fputs call, which of course is then
unaffected by the macro redirection.  (I don't know why this issue
only appears with -Os.)

This patch duly adds a use of libc_hidden_proto for fputs.  I see no
obvious reason why the fputs macro redirection is needed at all, but
this patch does not change it.

Tested for x86_64 (both that it removes this particular localplt
failure for -Os - but other such failures remain so the bug can't yet
be closed - and that the testsuite continues to pass without -Os).

7fc03cf320 Fix -Os feof_unlocked linknamespace, localplt issues (bug 15105, bug 19463).
Continuing the fixes for linknamespace and localplt test failures with
-Os that arise from functions not being inlined in that case, this
patch fixes such failures for feof_unlocked.

The usual approach is followed of adding __feof_unlocked (inlined when
feof_unlocked is), making calls use it when required for namespace
reasons, and using libc_hidden_proto / libc_hidden_weak for the
feof_unlocked weak alias when only localplt but not namespace issues
are involved.  In the case of getaddrinfo.c, use of __feof_unlocked
needs to be conditional since that code is also used in nscd (where
__feof_unlocked is not available).

Tested for x86_64 (both without -Os to make sure that case continues
to work, and with -Os to make sure all the relevant linknamespace and
localplt test failures are resolved).  Because of other such failures

63fb8f9aa9 Post-cleanup 2: minimize _G_config.h.
Nearly everything in _G_config.h is either junk or more appropriately
defined elsewhere:

 * _G_fpos_t, _G_fpos64_t, and _G_BUFSIZ are already completely unused.
 * All remaining uses of _G_va_list have been changed to __gnuc_va_list.
 * The definition of _G_HAVE_ST_BLKSIZE/_IO_HAVE_ST_BLKSIZE has
   been inlined into its sole use.
 * The complete definition of _G_iconv_t has been moved to libio.h and
   renamed _IO_iconv_t (all actual users used that name).
 * _G_IO_IO_FILE_VERSION is vestigial; some code cares whether
   _IO_stdin_used exists, but nothing looks at its value.  I've
   preserved the value as a hardwired constant in csu/init.c.
   This means csu/init.c no longer needs to include anything.
 * Many of the headers included by _G_config.h were already being
   included directly by either either libio.h or stdio.h; the
   remaining ones were moved to libio.h.
 * _G_HAVE_MREMAP is still relevant, because mremap genuinely is a
   Linux extension; it's not in POSIX and as far as I can tell it's
   not available on the Hurd either.  I also preserved _G_HAVE_MMAP,
   since it's conceivable someone would want to port glibc to a
   MMU-less, mmap-less environment in the future.  Both are now always
   defined to 1/0 as is the current convention, instead of the older
   1/undef convention.  These are the only symbols still defined in
   _G_config.h.
 * The actual inclusion of _G_config.h moves from libio.h to libioP.h,
   as this is where a potential override of _G_HAVE_MMAP happens.
 * The #ifdef logic in libioP.h controlling _IO_JUMPS_OFFSET has been
   simplified.

After this patch, the only surviving _G_ symbols are the struct tag
names _G_fpos_t and _G_fpos64_t, which are preserved for the sake of
C++ mangled names in applications, and _G_HAVE_MMAP and _G_HAVE_MREMAP,
which do not seem worth renaming.

Installed stripped libraries are unchanged by this patch.

	* bits/_G_config.h: Move back to sysdeps/generic/_G_config.h.
	Delete all contents except for definitions of _G_HAVE_MMAP and
	_G_HAVE_MREMAP.  Add commentary explaining those two symbols.
	* sysdeps/unix/sysv/linux/bits/_G_config.h: Move back to
	sysdeps/unix/sysv/linux/_G_config.h.  Make same content
	change as above.

	* libio/libio.h: Don't include bits/_G_config.h here.
	Include stddef.h with __need_wchar_t defined.  Include
	bits/types/__mbstate_t.h, bits/types/wint_t.h, and gconv.h.
	Define _IO_iconv_t here, directly.
	Don't define _IO_HAVE_ST_BLKSIZE.
	* libio/libioP.h: Include _G_config.h here.  Move include of
	shlib-compat.h up with rest of includes.  Simplify conditionals
	controlling definition of _IO_JUMPS_OFFSET.

	* csu/init.c: Remove always-true #if around entire file.
	Don't include stdio.h.  Set _IO_stdin_used to hardwired
	constant 0x20001, and update commentary.
	* include/stdio.h, sysdeps/ieee754/ldbl-opt/nldbl-compat.h:
	Replace all uses of _G_va_list with __gnuc_va_list.
	* libio/filedoalloc.c: Use #if defined _STATBUF_ST_BLKSIZE
	instead of #if _IO_HAVE_ST_BLKSIZE.
	* libio/fileops.c: Test _G_HAVE_MREMAP with #if, not #ifdef.
	* libio/iofdopen.c, libio/iofopen.c: Test _G_HAVE_MMAP with #if,
	not #ifdef.

6c6c962a20 Post-cleanup 1: move libio.h back out of bits/.
We can't go very far with libio cleanups as long as we still have
_IO_MTSAFE_IO, and I am not tackling that in this patch series,
but we can at least make the maze of stdio-related headers a
little less complicated.

In this patch, libio.h moves back out of bits/ into the top level of
the libio subdirectory, and is merged with libio/bits/libio-ldbl.h
(which also used to be installed) and include/libio.h.  Since almost
no files include libio.h directly, this is quite straightforward.

libio.h is now always used with _LIBC defined, so all of the _LIBC ||
_GLIBCPP_USE_WCHAR_T conditionals are unnecessary.  Similarly, the
ifdef nest surrounding the definition of _IO_fwide_maybe_incompatible
can collapse down to a single SHLIB_COMPAT check.  I also took the
opportunity to add some checks for configuration botches to libio.h.

Installed stripped libraries are unchanged by this patch.

        * libio/bits/libio.h: Move back to libio/libio.h and adjust
        multiple-include guard to match.
        Merge contents of libio/bits/libio-ldbl.h and include/libio.h
        into this file.
        Remove preprocessor conditionals that are always true and/or
        redundant to other preprocessor conditionals in the same nest.
        Include shlib-compat.h unconditionally.
        Error out if _LIBC is not defined, or if _ISOMAC is defined,
        or if _IO_MTSAFE_IO is defined but _IO_lock_t_defined is not
        defined after including stdio.h.
        Use __BEGIN_DECLS/__END_DECLS.

        * libio/bits/libio-ldbl.h, include/bits/libio.h: Delete file.
        * include/stdio.h, libio/iolibio.h, libio/libioP.h: Include
        libio.h as <libio/libio.h> rather than as <bits/libio.h>.

a4fea3f2c3 Don't install libio.h or _G_config.h.
We shipped 2.27 with libio.h and _G_config.h still installed but
issuing warnings when used.  Let's stop installing them early in 2.28
so that we have plenty of time to think of another plan if there are
problems.

The public stdio.h had a genuine dependency on libio.h for the
complete definitions of FILE and cookie_io_functions_t, and a genuine
dependency on _G_config.h for the complete definitions of fpos_t and
fpos64_t; these are moved to single-type headers.
bits/types/struct_FILE.h also provides a handful of accessor and
bitflags macros so that code is not duplicated between bits/stdio.h
and libio.h.  All the other _IO_ and _G_ names used by the public
stdio.h can be replaced with either public names or __-names.

In order to minimize the risk of breaking our own compatibility code,
bits/types/struct_FILE.h preserves the _IO_USE_OLD_IO_FILE mechanism
exactly as it was in libio.h, but you have to define _LIBC to use it,
or it'll error out.  Similarly, _IO_lock_t_defined is preserved
exactly, but will error out if used without defining _LIBC.

Internally, include/stdio.h continues to include libio.h, and libio.h
scrupulously provides every _IO_* and _G_* name that it always did,
perhaps now defined in terms of the public names.  This is how this
patch avoids touching dozens of files throughout glibc and becoming
entangled with the _IO_MTSAFE_IO mess.  The remaining patches in this
series eliminate most of the _G_ names.

Tested on x86_64-linux; in addition to the test suite, I installed the
library in a sysroot and verified that a simple program that uses
stdio.h could be compiled against the installed library, and I also
verified that installed stripped libraries are unchanged.

	* libio/_G_config.h, libio/libio.h: Delete file.

	* libio/bits/libio.h: Remove improper-inclusion guard.
	Include stdio.h and don't repeat anything that it does.
	Define _IO_fpos_t as __fpos_t, _IO_fpos64_t as __fpos64_t,

	here, in the "compatibility defines" section.  Remove an #if 0
	block.  Use the "body" macros from bits/types/struct_FILE.h to

	and _IO_ferror_unlocked.
	Move prototypes of __uflow and __overflow...

	* libio/stdio.h: ...here.  Don't include bits/libio.h.
	Don't define _STDIO_USES_IOSTREAM.  Get __gnuc_va_list
	directly from stdarg.h.  Include bits/types/__fpos_t.h,
	bits/types/__fpos64_t.h, bits/types/struct_FILE.h,
	and, when __USE_GNU, bits/types/cookie_io_functions_t.h.
	Use __gnuc_va_list, not _G_va_list; __fpos_t, not _G_fpos_t;
	__fpos64_t, not _G_fpos64_t; FILE, not struct _IO_FILE;
	cookie_io_functions_t, not _IO_cookie_io_functions_t;
	__ssize_t, not _IO_ssize_t.  Unconditionally define
	BUFSIZ as 8192 and EOF as (-1).

	* libio/bits/stdio.h: Add multiple-include guard.  Use the "body"
	macros from bits/types/struct_FILE.h instead of _IO_* macros
	from libio.h; use __gnuc_va_list instead of va_list and __ssize_t
	instead of _IO_ssize_t.
	* libio/bits/stdio2.h: Similarly.

	* libio/iolibio.h: Add multiple-include guard.

e0d2eb5a79 linux: Implement tmpfile with O_TMPFILE (BZ#21530)
This patch adds O_TMPFILE support to tmpfile on Linux.  This is

difference the file descriptor creation is parameterized to
compartmentalize Linux only open flags (O_TMPFILE) on sysdeps.

7c3018f9e4 Suppress internal declarations for most of the testsuite.
This patch adds a new build module called 'testsuite'.
IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus
(which means several ad-hoc tests for __cplusplus can go away).
libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is
defined; in particular, _ISOMAC mode does not get config.h
automatically anymore.

There are still quite a few tests that need to see internal gunk of
one variety or another.  For them, we now have 'tests-internal' and
'test-internal-extras'; files in this category will still be compiled
with MODULE_NAME=nonlib, and everything proceeds as it always has.
The bulk of this patch is moving tests from 'tests' to
'tests-internal'.  There is also 'tests-static-internal', which has
the same effect on files in 'tests-static', and 'modules-names-tests',
which has the *inverse* effect on files in 'modules-names' (it's
inverted because most of the things in modules-names are *not* tests).
For both of these, the file must appear in *both* the new variable and
the old one.

There is also now a special case for when libc-symbols.h is included
without MODULE_NAME being defined at all.  (This happens during the
creation of libc-modules.h, and also when preprocessing Versions
files.)  When this happens, IS_IN is set to be always false and
_ISOMAC is *not* defined, which was the status quo, but now it's
explicit.

The remaining changes to C source files in this patch seemed likely to
cause problems in the absence of the main change.  They should be
relatively self-explanatory.  In a few cases I duplicated a definition
from an internal header rather than move the test to tests-internal;
this was a judgement call each time and I'm happy to change those
however reviewers feel is more appropriate.

	* Makerules: New subdir configuration variables 'tests-internal'
	and 'test-internal-extras'.  Test files in these categories will
	still be compiled with MODULE_NAME=nonlib.  Test files in the
	existing categories (tests, xtests, test-srcs, test-extras) are
	now compiled with MODULE_NAME=testsuite.
	New subdir configuration variable 'modules-names-tests'.  Files
	which are in both 'modules-names' and 'modules-names-tests' will
	be compiled with MODULE_NAME=testsuite instead of
	MODULE_NAME=extramodules.
	(gen-as-const-headers): Move to tests-internal.
	(do-tests-clean, common-mostlyclean): Support tests-internal.
	* Makeconfig (built-modules): Add testsuite.
	* Makefile: Change libof-check-installed-headers-c and
	libof-check-installed-headers-cxx to 'testsuite'.
	* Rules: Likewise.  Support tests-internal.
	* benchtests/strcoll-inputs/filelist#en_US.UTF-8:
	Remove extra-modules.mk.

	* config.h.in: Don't check for __OPTIMIZE__ or __FAST_MATH__ here.
	* include/libc-symbols.h: Move definitions of _GNU_SOURCE,
	PASTE_NAME, PASTE_NAME1, IN_MODULE, IS_IN, and IS_IN_LIB to the
	very top of the file and rationalize their order.
	If MODULE_NAME is not defined at all, define IS_IN to always be
	false, and don't define _ISOMAC.
	If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are
	true, define _ISOMAC and suppress everything else in this file,
	starting with the inclusion of config.h.
	Do check for inappropriate definitions of __OPTIMIZE__ and
	__FAST_MATH__ here, but only if _ISOMAC is not defined.
        Correct some out-of-date commentary.

	* include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE
	and _Mlong_double_ before including math.h.
	* include/string.h: If _ISOMAC is defined, don't expose
	_STRING_ARCH_unaligned. Move a comment to a more appropriate
	location.

	* include/errno.h, include/stdio.h, include/stdlib.h, include/string.h
	* include/time.h, include/unistd.h, include/wchar.h: No need to

544ce845de getopt: clean up error reporting
getopt can print a whole bunch of error messages, and when used
standalone (from gnulib) it uses fprintf to do that.  But fprintf is a
cancellation point and getopt isn't, and also applying fprintf to a
stream in wide-character mode is not allowed.

glibc has an internal function called __fxprintf that writes a narrow
format string to a stream regardless of mode, but it only handles
ASCII format strings, and it's still a cancellation point.  getopt's
messages are translated, so they might not be ASCII.  So getopt has an
error message to an asprintf buffer, monkeys with internal flag bits
on stderr to disable cancellation, and then calls
__fxprintf(stderr, "%s", buffer).  There isn't even a helper function,
the code is duplicated every time.

This patch fixes __fxprintf to handle arbitrary multibyte format
strings, and adds a variant __fxprintf_nocancel that does the same
thing but also isn't a cancellation point.  (It still _works_ by
monkeying with internal flag bits on the FILE, but that's not really a
layering violation for code in stdio-common.)  All of the #ifdef _LIBC
blocks can then be reduced to their standalone versions with a little
help from some macros at the top of the file.

I also wrote a test case to verify that getopt really isn't a
cancellation point, and I'm glad I did, because it found two bugs, one
of which wasn't even to do with cancellation (see previous patch).

	* stdio-common/fxprintf.c (__fxprintf_nocancel): New function.
	(locked_vfxprintf): New helper function. Handle arbitrary
	multibyte strings, not just ASCII.
	* include/stdio.h: Declare __fxprintf_nocancel.

	* posix/getopt.c: When _LIBC is defined, define fprintf to
	__fxprintf_nocancel, flockfile to _IO_flockfile, and
	funlockfile to _IO_funlockfile.  When neither _LIBC nor
	_POSIX_THREAD_SAFE_FUNCTIONS is defined, define flockfile and
	funlockfile as no-ops.  (_getopt_internal_r): Remove all
	internal #ifdef _LIBC blocks; the standalone error-printing
	code can now be used for libc as well.  Add an
	flockfile/funlockfile pair around one case where the error
	message is printed in several chunks.  Don't use fputc.

	* posix/tst-getopt-cancel.c: New test.
	* posix/Makefile: Run it.

7caa5054af Clean up conditionals for declaration of gets.
gets has the dubious honor of being the only C89 library feature that
has been completely removed from the current C and C++ standards.
glibc follows suit by not declaring it in _GNU_SOURCE mode either,
but it remains present in older compatibility modes.  Internally,
two test cases need to see stdio.h make the declaration, but all our
internal code is of course compiled under _GNU_SOURCE.  This is currently
kludged by duplicating the gets declaration, fortify wrapper and all,
in include/stdio.h.  Also, the conditional in the public headers for
deciding when to declare gets is complicated and repeated in two places.

This patch adds a new macro to features.h that encapsulates the
complicated rule for when to declare gets.  stdio.h and bits/stdio2.h
then simply test __GLIBC_USE (DEPRECATED_GETS), and instead of having
a duplicate gets declaration in include/stdio.h, debug/tst-chk1.c and
stdio-common/tst-gets.c can force gets to be declared.

        * include/features.h (__GLIBC_USE_DEPRECATED_GETS): New macro.
        * libio/stdio.h, libio/bits/stdio2.h: Condition gets on
        __GLIBC_USE (DEPRECATED_GETS).  Update comments to indicate
        gets was removed from C++ in C++14.
        * include/stdio.h: Remove redundant declaration of gets.
        * debug/tst-chk1.c, stdio-common/tst-gets.c: Force gets to
        be declared, since we are testing it.
        * stdio-common/Makefile (tst-gets.c): Compile with
        -Wno-deprecated-declarations.

61158ffa9a Fix crypt snprintf namespace (bug 20829).
Extending linknamespace tests to cover libcrypt showed that crypt
brings in references to snprintf, but is in XPG3 and XPG4 which don't
have snprintf.  This patch fixes it to use __snprintf instead,
exporting __snprintf from libc.so at version GLIBC_PRIVATE and adding
libc_hidden_proto / libc_hidden_def accordingly.

Tested for x86_64 and x86, in conjunction with the testsuite changes
to enable linknamespace testing for libdl and libcrypt.  Also tested
(compilation only) for powerpc to make sure there were no problem
interactions with the optional-long-double handling for snprintf.

fdb7d390dd libio: fmemopen rewrite to POSIX compliance
This patch added a new fmemopen version, for glibc 2.22, that aims to be
POSIX complaint.  It fixes some long-stading glibc fmemopen issues, such
as:

* it changes the way fseek with SEEK_END works on fmemopen to seek
  relative to buffer size instead of first '\0'.  This is default mode and
  'b' opening mode does not change internal behavior (bz#6544).

* fix apending opening mode to use as start position either first null
  byte of len specified in function call (bz#13152 and #13151).

* remove binary option 'b' and internal different handling (bz#12836)

* fix seek/SEE_END with negative values (bz#14292).

version (2.2.5).

eb1fae6a45 Fix getpass fflush_unlocked namespace (bug 18540).
The getpass function (XPG3 / XPG4 / UNIX98) calls fflush_unlocked (not
in any of those standards).  This patch fixes this by making
fflush_unlocked into a weak alias for __fflush_unlocked and calling
__fflush_unlocked from getpass.

Tested for x86_64 and x86 (testsuite, and that disassembly of
installed stripped shared libraries is unchanged by the patch).

be7dc2b77e Fix syslog dprintf namespace (bug 18534).
syslog functions bring in references to dprintf, which wasn't added to
POSIX until the 2008 edition and so isn't in various standards
containing the syslog functions.  This patch fixes this by making
dprintf into a weak alias of __dprintf and using __dprintf as
appropriate.

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

3164bf09f5 Fix syslog fputs_unlocked namespace (bug 18530).
syslog (XSI POSIX) brings in references to fputs_unlocked (not
POSIX).  This patch fixes this by making fputs_unlocked into a weak
alias for __fputs_unlocked and using __fputs_unlocked as needed.  (No
linknamespace test XFAILs are removed because there are other failures
from syslog as well.)

Tested for x86_64 and x86 (testsuite, and comparison of disassembly of
installed stripped shared libraries).  Disassembly of installed
stripped shared libraries is unchanged on x86_64; on x86, I see some
small changes to instruction ordering and register choice, with no
apparent reason for such changes to be related to this patch, but they
also seem completely harmless with no change to code size.

711f67a789 Fix open_memstream namespace (bug 18498).
open_memstream is new in the 2008 edition of POSIX.  However, the
older functions getopt, closelog and fmtmsg all bring in references to
it.  This patch fixes this in the usual way, making open_memstream
into a weak alias of __open_memstream and calling __open_memstream
from the relevant places.

Tested for x86_64 and x86 (testsuite, and that disassembly of
installed shared libraries is unchanged by the patch).  32-bit builds
produce an XPASS for conform/POSIX/unistd.h/linknamespace after this
patch (because the only cause of failure left there now is 64-bit
specific); that will disappear once the 64-bit failure is resolved and
the XFAIL removed at that time.

330fadfc62 Ensure `wint_t' is defined before use in include/stdio.h
While trying to get nptl/tst-initializers1.c to include the test skeleton, I
came across a couple of speed bumps. Firstly: after making the appropriate
changes to the test, running `make check' led to this error:

> In file included from ../malloc/malloc.h:24:0,
..
>                  from tst-initializers1.c:60:
> ../include/stdio.h:111:1: error: unknown type name `wint_t'
>  extern wint_t __getwc_unlocked (FILE *__fp);

So, `wint_t' is used before being defined. Question: Why did test-skeleton.c
not cause this error in any of the other tests that include it?

Anyway, I noticed include/stdio.h includes stddef.h, which in turn defines
`wint_t', but only if `__need_wint_t' is defined. So I put in a
`#define __need_wint_t' before the include to get rid of the error. Is that
the correct fix?

A subsequent `make && make check' led to this second error:

>                  from tst-initializers1-c89.c:1:
> ../test-skeleton.c: In function `main':
> ../test-skeleton.c:356:11: error: `for' loop initial declarations are only
>  allowed in C99 mode
>            for (struct temp_name_list *n = temp_name_list;

Although there seem to be several other C89 no-noes in test-skeleton.c, I
needed only to fix this specific one for gcc-4.8.3 to stop complaining.

c4eae75271 Fix __get_nprocs fgets_unlocked namespace (bug 17582).
__get_nprocs is called from malloc code, but calls fgets_unlocked,
which is not an ISO C or POSIX function.  This patch fixes it to call
a new __fgets_unlocked name instead.

Note: there are various other uses of fgets_unlocked in glibc's
libraries, and I haven't yet investigated which others might also be
problematic (called directly or indirectly from standard functions)
and so need to change to use __fgets_unlocked.

Tested for x86_64 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch).

	[BZ #17582]
	* libio/iofgets.c [weak_alias && !_IO_MTSAFE_IO]
	(__fgets_unlocked): Add alias of _IO_fgets.  Use libc_hidden_def.
	* libio/iofgets_u.c (fgets_unlocked): Rename to __fgets_unlocked
	and define as weak alias of __fgets_unlocked.  Use
	libc_hidden_weak.
	(__fgets_unlocked): Use libc_hidden_def.
	* include/stdio.h (__fgets_unlocked): Declare.  Use

5a6fa4d7ed Fix tzfile.c namespace (bug 17583).
tzfile.c is brought in by various ISO C functions, but calls fileno,
fread_unlocked and ftello, which are not ISO C functions.  This patch
adds names __fileno, __fread_unlocked and __ftello for those
functions, making tzfile.c use those new names.

Note: there are various uses of fileno elsewhere in glibc that I
didn't change, although it may turn out that some of those also need
to use __fileno.

Tested for x86_64 with the glibc testsuite.  Changed line numbers in
tzfile.c cause changes in assertions, and for some reason this ends up
with different instruction choice and register allocation, affecting
the size of __tzfile_read and so making comparison of disassembly for
libc.so problematic.

	[BZ #17583]
	* libio/fileno.c (fileno): Rename to __fileno and define as weak
	alias of __fileno.  Use libc_hidden_weak.
	(__fileno): Use libc_hidden_def.
	[weak_alias] (fileno_unlocked): Define as weak alias of __fileno.
	* libio/ftello.c (ftello): Rename to __ftello and define as weak
	alias of __ftello.

	libc_hidden_def.
	(fread_unlocked): Don't use libc_hidden_ver.
	* libio/iofread_u.c (fread_unlocked): Rename to __fread_unlocked
	and define as weak alias of __fread_unlocked.  Don't use
	libc_hidden_def.
	(__fread_unlocked): Use libc_hidden_def.
	* include/stdio.h (__fileno): Declare.  Use libc_hidden_proto.

	(fread_unlocked): Don't use libc_hidden_proto.
	(__fread_unlocked): Declare.  Use libc_hidden_proto.
	* time/tzfile.c (__tzfile_read): Use __fileno, __fread_unlocked
	and __ftello instead of fileno, fread_unlocked and ftello.

b50f8e42ba Check for valid stack frame in longjmp.
If longjmp restores the stack frame to an address which is beyond
the stack frame at the time of the longjmp call it would install

defined, longjmp will now bail out in this situation.
