935ab81792 Fix resolver bind, getsockname namespace (bug 17733).
On Linux architectures using socketcall, the resolver ends up bringing
in strong symbols for bind and getsockname, which are not in
POSIX.1-1996.  This causes linknamespace test failures:

FAIL: conform/POSIX/pthread.h/linknamespace
FAIL: conform/POSIX/sched.h/linknamespace
FAIL: conform/POSIX/time.h/linknamespace

These functions are defined as strong symbols with __bind and
__getsockname as weak aliases.  This patch switches this to the other
way round by removing the NO_WEAK_ALIAS definitions and so letting the
default case in socket.S act; I see no reason for the existing
arrangements.

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

	[BZ #17733]
	* sysdeps/unix/sysv/linux/bind.S (NO_WEAK_ALIAS): Do not define.
	(__bind): Do not define as weak alias.
	* sysdeps/unix/sysv/linux/getsockname.S (NO_WEAK_ALIAS): Do not
	define.
	(__getsockname): Do not define as weak alias.

cc8623f196 Require bison 2.7 or newer for regenerating intl/plural.y
The merge of the latest gettext code introduced changes to the yacc
parser source that are incompatible with versions of bison older
than 2.7. Add a configure check for the appropriate versions and
document the requirement in INSTALL.

ChangeLog:

2014-12-22  Will Newton  <will.newton@linaro.org>

	* manual/install.texi: Document that we require bison 2.7
	or above.
	* INSTALL: Regenerate.
	* configure.ac: Use AC_CHECK_PROG_VER instead of
	AC_PATH_PROG when checking for bison and check for
	version 2.7 or above.
	* configure: Regenerate.

050f7298e1 Add hidden __tls_get_addr/___tls_get_addr alias
__tls_get_addr/___tls_get_addr is always defined in ld.so.  There is
no need to call them via PLT inside ld.so.  This patch adds the hidden
__tls_get_addr/___tls_get_addr aliases and calls them directly from
_dl_tlsdesc_dynamic.  There is no need to set up the EBX register in
i386 _dl_tlsdesc_dynamic when calling the hidden ___tls_get_addr.

	* elf/dl-tls.c (__tls_get_addr): Provide the hidden definition
	if not defined.
	* sysdeps/i386/dl-tls.h (___tls_get_addr): Provide the hidden
	definition.

	hidden ___tls_get_addr.
	* sysdeps/x86_64/dl-tlsdesc.S (_dl_tlsdesc_dynamic): Call the
	hidden __tls_get_addr.
	* sysdeps/generic/localplt.data (__tls_get_addr): Removed.
	* sysdeps/unix/sysv/linux/i386/localplt.data (___tls_get_addr):

95dee05f17 tilegx: fix strstr to build and link better
The two_way_short_needle() routine included from str-two-way.h
is not used, so mark it so to avoid compiler warnings.

Calling strnlen() breaks linknamespace tests, so change it
to __strnlen().

c9c1a2d02c Replace 1L with (mp_limb_t) 1
X86-64 and x32 use sysdeps/i386/ldbl2mpn.c.  res_ptr is a pointer
to mp_limb_t, which is long for i386 and x86-64 and long long for
x32.  On x32, I got

../sysdeps/x86_64/../i386/ldbl2mpn.c: In function ‘__mpn_extract_long_double’:

ea41469b7a Fix profil_counter namespace (bug 17725).
On ARM, where profil_counter is not static, it is brought in by
references to various standard functions, as noted in
<https://sourceware.org/ml/libc-alpha/2014-11/msg00890.html>, although
it is not a standard function itself.  I don't know if this also
causes test failures on SPARC, although I see no reason for it not to
do so.

This patch fixes this namespace issue.  profil_counter is renamed to
__profil_counter and made a weak alias on ARM and SPARC.  Because of
the uses in profil.c / sprofil.c it seems simplest to make the rename
globally, including on the other architectures for which
profil_counter was static and so the change is of no substance.  The
variant names profil_counter_* used in sprofil.c are also renamed to
start with __ so that undesired function names do not get exported in
static libc.

As I noted in bug 17726, profil_counter should probably be a compat
symbol on ARM and SPARC, so it wouldn't exist at all in static libc
even as a weak alias.  Since defining a compat symbol still requires
an internal name as a target of an alias, this patch still seems
reasonable as an intermediate step towards that goal: it wouldn't be
possible for the function simply to be static profil_counter on ARM
and SPARC with profil_counter also being the exported compat symbol
name, so profil.c / sprofil.c would still need to be prepared to call
the function under another name (here, __profil_counter).

Tested for x86_64 (testsuite, and that stripped installed shared
libraries are unchanged by the patch) and ARM (ABI and linknamespace
tests - this patch reduces the number of linknamespace failures I see
on ARM from 227 to 5, the residue being math.h failures for fe*
functions and for j0l/j1n/jnl/y0l/y1l/ynl aliases).

8ac5a76a99 Fix resolver inet_* namespace (bug 17722).
Parts of the resolver brought in by pthreads (at least) use inet_*
functions that aren't in the 1995/6 edition of POSIX that introduced
pthreads (or in one case, use __inet_aton which is then defined in the
same file as non-weak inet_addr).  This patch fixes this by making the
affected functions into weak alias for __inet_* and using those names
in the problematic resolver code.

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

380292ba8b Fix x86_64 memrchr namespace (bug 17719).
On x86_64, memrchr (not a standard function) is defined as a strong
symbol, instead of a weak alias of __memrchr as on other
architectures.  This results in linknamespace test failures from the
use of __memrchr from dirname.  (Not a conformance issue because of
the mem* reservation, but contrary to glibc conventions.)  This patch
makes x86_64 follow other architectures by defining memrchr as a weak
alias.

a0d424ef9d Fix 'array subscript is above array bounds' warning in res_send.c
I see this warning in my build on F21 x86_64, which seems to be due to
a weak check for array bounds.  Fixed by making the bounds check
stronger.

This is not an actual bug since nscount is never set to anything
greater than MAXNS.  The compiler however does not know this, so we
need the stronger bounds check to quieten the compiler.
