H.J. Lu 8bcdb7e0c5 Mark internal functions with attribute_hidden [BZ #18822] 
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.

Size comparison of libc.so:

On x86-64:
        text	   data	    bss	    dec	    hex
Before: 1728577	  20584	  17088	1766249	 1af369
After : 1728593	  20584	  17088	1766265	 1af379

The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.

On i686:
        text	   data	    bss	    dec	    hex
Before: 1869039	  11444	  11112	1891595	 1cdd0b
After : 1868635	  11444	  11112	1891191	 1cdb77

The code size is decreased by avoiding GOT/PLT for hidden functions.

Adhemerval Zanella ccf970c7a7 posix: Add compat glob symbol to not follow dangling symbols 
This patch follows commit 5554304f0 (posix: Allow glob to match dangling
symlinks [BZ #866]) by adding a compat symbol that follow previous
semantic of not following dangling symlinks and thus avoiding call
gl_lstat with GLOB_ALTDIRFUNC.

It avoids failure with old binaries that not set the alternate function
pointer for lstat (GNUmake for instance).  The following scenario, for
instance, fails with current GNUmake because glibc will access unitialized
memory when calling gl_lstat:

  $ cat src/t/t.c
  int main ()
  {
    return 0;
  }
  $ cat Makefile
  SRC = $(wildcard src/*/t.c)
  OBJ = $(patsubst src/%.c, obj/%.o, $(SRC))

  prog:           $(OBJ)
                  $(CC) $(CFLAGS) $(LDFLAGS) $(LIBS) $(OBJ) -o prog

  obj/%.o:        src/%.c
                  $(CC) $(CFLAGS) -c $< -o $@
  $ make

This works as expected with the patch applied.  Since it is for generic
ABI, default compat symbols are added with override for Linux due LFS.
Now we have two compat symbols for glob on Linux:

  1. sysdeps/unix/sysv/linux/oldglob.c which implements glob64 with
     the old dirent layout.  For this implementation I also set it to
     not follow dangling symlinks (which is the safest path).

  2. sysdeps/unix/sysv/linux/glob{64}-lstat-compat.c which implements
     the compat symbol for dangling symlinks.  As for generic glob,
     the implementation uses XSTAT_IS_XSTAT64 to define whether
     both __glob_lstat_compat and __glob64_lstat_compat should be
     different implementations.  For archictures that define
     XSTAT_IS_XSTAT64, __glob_lstat_compat is aliased to
     __glob64_lstat_compat.

  3. sysdeps/unix/sysv/linux/alpha/oldglob.c with a different glob_t
     layout.  As for 1. this patch changes it to not follow dangling
     symlinks.

The patch also bumps _GNU_GLOB_INTERFACE_VERSION to 2 to advertise the
new semantic.  On GNUmake, for instance, it will force to it use its
internal glob implementation instead and avoiding triggering the same
failure on builds against newer GLIBCs.

Checked on x86_64-linux-gnu and i686-linux-gnu.  I also checked
with a build against the major ABIs required to check for the abilist.

The changes should also work on gnulib (I run gnulib-tool.py check glob
and it shown no regressions).

Szabolcs Nagy f5f0f52651 New expf and exp2f version without SVID compat wrapper 
This patch changes the expf and exp2f error handling semantics to only
set errno accoring to POSIX rules. New symbol version is introduced at
GLIBC_2.27.

The old wrappers are kept for compat symbols.

Internal calls to __expf now get the new error semantics, this seems to
only affect sysdeps/i386/fpu/s_expm1f.S where the errno-only behaviour
should be correct.

ia64 needed assembly change to have the new and compat versioned symbol
map to the same function.

Joseph Myers d82468d100 Fix fexecve build where syscall macros call sizeof. 
The recent fexecve changes broke the build on (at least) alpha (maybe
other configurations, that was the first breakage I saw in my
build-many-glibcs.py run):

Joseph Myers 27342d1783 Add fcntl sealing interfaces from Linux 3.17 to bits/fcntl-linux.h. 
While reviewing Linux 4.13 for glibc header changes needed, I noticed
that bits/fcntl-linux.h was missing F_ADD_SEALS etc. from Linux 3.17.

I didn't find any discussion indicating this omission is deliberate.
Now, these interfaces can only be used with file descriptors created
with memfd_create, and we don't have a memfd_create wrapper in glibc
(a patch was submitted in October 2014, albeit without documentation /
tests, and discussions continued over the next few months, but without
consensus on whether to add the interface - and we still lack any
general consensus on syscall wrappers), but I don't think that's a
reason to exclude the constants from bits/fcntl-linux.h (especially as
the header does not look compatible with simultaneously including
linux/fcntl.h).

(Some of those 2014/2015 discussions raised concerns about difficulty
using the memfd_create / sealing interface, but those seem to me more
like a question of whether it should be part of the OS-independent GNU
API - in my view, even fairly specialized syscalls ought to have
wrappers added to glibc if not obsolescent, but there may be cases
where we only want to include them in the Linux-specific API and
anything in the OS-independent GNU API should be different - rather
than being relevant to whether constants for use with fcntl should
appear in headers.)

Adhemerval Zanella 116f1c64d8 posix: Consolidate Linux glob implementation 
This patch consolidates the glob implementation.  The main changes are:

  * On Linux all implementation now uses the default one at
    sysdeps/unix/sysv/linux/glob{free}{64}.c with the exception
    of alpha (which requires specific versioning) and s390-32 (which
    different than other 32 bits ports it does not add a compat one
    symbol for 2.1 version).

  * The default implementation uses XSTAT_IS_XSTAT64 to define whether
    both glob{free} and glob{free}64 should be different implementations.
    For archictures that define XSTAT_IS_XSTAT64, glob{free} is an alias
    to glob{free}64.

  * Move i386 olddirent.h header to Linux default directory, since it is
    the only header with this name and it is shared among different
    architectures (and used on compat glob symbol as well).

Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.

Adhemerval Zanella c66c908230 posix: Sync glob with gnulib [BZ #1062] 
This patch syncs posix/glob.c implementation with gnulib version
b5ec983 (glob: simplify symlink detection).  The only difference
to gnulib code is

  * DT_UNKNOWN, DT_DIR, and DT_LNK definition in the case there
    were not already defined.  Gnulib code which uses
    HAVE_STRUCT_DIRENT_D_TYPE will redefine them wrongly because
    GLIBC does not define HAVE_STRUCT_DIRENT_D_TYPE.  Instead
    the patch check for each definition instead.

Also, the patch requires additional globfree and globfree64 files
for compatibility version on some architectures.  Also the code
simplification leads to not macro simplification (not need for
NO_GLOB_PATTERN_P anymore).

Adhemerval Zanella 102dde842a Remove NO_CANCELLATION macro 
The NO_CANCELLATION macro is used currently on generic headers to
define non cancellable syscalls and on Linux fcntl to implement the non
cancellable variation.  Former should be single-handled by not-cancel.h
header and former could be simplified build both cancellable and non
cancellable for default objects and alias the non-cancellable to default
one for rtld ones (since Linux already support cancellation as default).

This patch thus removes the NO_CANCELLATION macro and its usage.  The
generic non cancellable fcntl is route to internal fcntl.

Joseph Myers 4fa9b3bfe6 Fix mcontext_t sigcontext namespace (bug 21457). 
This patch completes the ucontext.h namespace fixes by fixing issues
related to the use of struct sigcontext as mcontext_t, and inclusion
of <bits/sigcontext.h> even when struct sigcontext is not so used.

Inclusion of <bits/sigcontext.h> by <sys/ucontext.h> is removed; the
way to get the sigcontext structure is by including <signal.h> (in a
context where __USE_MISC is defined); the sysdeps/generic version of
sys/ucontext.h keeps the inclusion by necessity, with a comment about
how this is not namespace-clean, but the only configuration that used
it, MicroBlaze, gets its own version of the header in this patch.
Where mcontext_t was typedefed to struct sigcontext, the contents of
struct sigcontext are inserted (with appropriate namespace handling to
prefix fields with __ when __USE_MISC is not defined); review should
check that this has been done correctly in each case, whether the
definition of struct sigcontext comes from glibc headers or from the
Linux kernel.  This changes C++ name mangling on affected
architectures (which do not include x86_64/x86).

Tested for x86_64, and with build-many-glibcs.py.

Adhemerval Zanella 319cbbf633 MIPS/o32: Fix internal_syscall5/6/7 
Fix a commit cc25c8b4c1 ("New pthread rwlock that is more scalable.")
regression and prevent uncontrolled stack space usage from happening
when a 5-, 6- or 7-argument syscall wrapper is placed in a loop.

The cause of the problem is the use of `alloca' in regular MIPS/Linux
wrappers to force the use of the frame pointer register in any function
using one or more of these wrappers.  Using the frame pointer register
is required so as not to break frame unwinding as the the stack pointer
is lowered within the inline asm used by these wrappers to make room for
the stack arguments, which 5-, 6- and 7-argument syscalls use with the
o32 ABI.

The regular MIPS/Linux wrappers are macros however, expanded inline, and
stack allocations made with `alloca' are not discarded until the return
of the function they are made in.  Consequently if called in a loop,
then virtual memory is wasted, and if the loop goes through enough
iterations, then ultimately available memory can get exhausted causing
the program to crash.

Address the issue by replacing the inline code with standalone assembly
functions, which rely on the compiler arranging syscall arguments
according to the o32 function calling convention, which MIPS/Linux
syscalls also use, except for the syscall number passed and the error
flag returned.  This way there is no need to fiddle with the stack
pointer anymore and all that has to be handled in the new standalone
functions is the special handling of the syscall number and the error
flag.

Redirect 5-, 6- or 7-argument MIPS16/Linux syscall wrappers to these new
functions as well, so as to avoid an unnecessary double call the
existing wrappers would cause with the new arrangement.

Florian Weimer 2dba5ce7b8 <bits/syscall.h>: Use an arch-independent system call list on Linux 
This commit changes the way the list of SYS_* system call macros is
created on Linux.  glibc now contains a list of all known system
calls, and the generated <bits/syscall.h> file defines the SYS_ macro
only if the correspnding __NR_ macro is defined by the kernel headers.

As a result, glibc does not have to be rebuilt to pick up system calls
if the glibc sources already know about them.  This means that glibc
can be built with older kernel headers, and if the installed kernel
headers are upgraded afterwards, additional SYS_ macros become
available as long as glibc has a record for those system calls.

Adhemerval Zanella ebd6f0076a Remove cancellation support for syscall generation 
This patch removes the cancellation mark from the auto-generation syscall
script.  Now all the cancellable syscalls are done throught C code using
the SYSCALL_CANCEL macro.  It simplifies the assembly required to each
architecture port, since the SYSCALL_CANCEL uses the already defined
INLINE_SYSCALL macros, and allows a more straigh fix on cancellation
machanism (since no more specific assembly fixes will be required).

Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,

Adhemerval Zanella 2b0b9a1c85 Consolidate remaning non cancellable definitions 
This patch consolidate the remaning non cancellable syscall definitions
on not-cancel.h header.  They are:

  * __fcntl_nocancel: Moved from fcntl.h to not-cancel.h.
  * __sigsuspend_nocancel: Removed since 988f991b50 it is not used or
    defined anymore.
  * __nanosleep_nocancel: Removed since 6f33fd046b it is defined on
    not-cancel.h.

Now all non-cancellable syscall definition are defined on not-cancel
(the only exceptions is the stdio symbol __fxprintf_nocancel which

Adhemerval Zanella 78ca091cdd Fix {INLINE,INTERNAL}_SYSCALL macros for x32 
The problem for x32 is the {INTERNAL,INLINE}_SYSCALL C macros explicit
cast the arguments to 'long int', thus passing as 32 bits arguments
that should be passed to 64 bits.

Previous x32 implementation uses the auto-generated syscalls from
assembly macros (syscalls.list), so the {INTERNAL,INLINE}_SYSCALL
macros are never used with 64 bit argument in x32 (which are
internally broken for this ILP).

To fix it I used a strategy similar to MIPS64n32 (although both
ABI differs for some syscalls on how top pass 64-bits arguments)
where argument types for kernel call are defined using GCC extension
'typeof' with a arithmetic operation.  This allows 64-bits arguments
to be defined while 32-bits argument will still passed as 32-bits.

I also cleanup the {INLINE,INTERNAL}_SYSCALL definition by defining
'inline_syscallX' instead of constructing the argument passing using
macros (it adds some readability) and removed the ununsed
INTERNAL_SYSCALL_NCS_TYPES define (since the patch idea is exactly to
avoid requiric explicit types passing).

Tested on x86_64 and x32.

Joseph Myers 80f91666fe Fix sparc32 bits/long-double.h (bug 21987). 
My refactoring of long double information

commit 0acb8a2a85
Author: Joseph Myers <joseph@codesourcery.com>
Date:   Wed Dec 14 18:27:56 2016 +0000

    Refactor long double information into bits/long-double.h.

resulted in sparc32 configurations installing the ldbl-opt version of
bits/long-double.h instead of the intended
sysdeps/unix/sysv/linux/sparc version.

For sparc32 by itself, this is not a problem, since the ldbl-opt
version is correct for sparc32.  However, both sparc32 and sparc64 are
supposed to install sets of headers that work for both of them, so
that a single sysroot, whichever order the libraries are built and
installed in, works for both.  The effect of having the wrong version
installed is that you end up with a miscompiled sparc64 libstdc++
which fails glibc's configure tests for the C++ compiler.

This patch moves the header from sysdeps/unix/sysv/linux/sparc to
separate copies of the same file for sparc32 and sparc64, to ensure it
comes before ldbl-opt in the sysdeps directory ordering.

Tested with build-many-glibcs.py for sparc64-linux-gnu and
sparcv9-linux-gnu.

Joseph Myers 831bbd5527 Remove SPARC sqrt wrappers (bug 21973). 
This patch removes the SPARC-specific wrappers for sqrt and sqrtf.

These wrappers, by adding architecture-specific uses of _LIB_VERSION
and __kernel_standard, unnecessarily complicate cleanups of libm error
handling.  They also do not serve a useful optimization purpose.  GCC
knows about sqrt as a built-in function, and can generate direct calls
to a hardware square root instruction, either on its own, in the
-fno-math-errno case, or together with an inline check for the
argument being negative and a call to the out-of-line sqrt function
for error handling only in that case (and has been able to do so for a
long time).  Thus in practice the wrapper will only be called only in
the case of negative arguments, which is not a case it is useful to
optimize for.

The removal of the wrappers also uncovers, and fixes, an old bug.
32-bit SPARC libm used (checked with glibc 2.8 binaries) to have a
sqrtl compat symbol, version GLIBC_2.0, for old binaries when sqrtl
was an alias of sqrt (I don't have pre-glibc-2.4 binaries for SPARC to
hand to check for the sqrtl symbol in those).  This disappeared,
probably with:

commit 8847f03770
Author: David S. Miller <davem@davemloft.net>
Date:   Tue Feb 28 22:37:58 2012 -0800

    Add sparc optimized sqrt{,f}.

Removing the wrappers brings back the generic ldbl-opt logic for
creating such compat symbols, and so restores the compat symbol that
should be there.  This could of course also be fixed in the wrappers -
but as noted above, the wrappers are optimizing a case it's not useful
to optimize, so the bug of the missing compat symbol serves to
illustrate the risks involved with the extra complexity of
architecture-specific function versions where not needed.

Tested with build-many-glibcs.py.

be just a macro to call the default respective symbol while on Linux
will be a internal one.

Also, since it is used on libcrypto it is also exported in GLIBC_PRIVATE
namespace.

Joseph Myers 67f0aff0c6 Fix sigval namespace (bug 21944). 
XPG4.2 defines the siginfo_t type, but not union sigval or its
contents (which were added in the 1993 edition of POSIX.1), resulting
in namespace violations for sigval, sival_int and sival_ptr for
signal.h and sys/wait.h for that standard because those headers
incorrectly expose those names in that case.

This patch fixes this problem.  The public type in this case is union
sigval, but various places in the headers use the sigval_t name for
it; direct uses of union sigval are already properly guarded or in
headers not in XPG4.2.  Now, sigval_t, although not a standard name,
does seem to be widely used outside glibc.  The approach taken by this
patch is to make installed headers use the name __sigval_t instead.
__sigval_t is then defined to either union sigval or union __sigval
(where union __sigval has __-prefixed member names as well), depending
on whether there are any namespace issues with the union sigval name
and its members.  In the case where union __sigval is used, sigval_t
is not defined at all, to avoid the problem of sigval_t having a C++
mangled name that depends on feature test macros.  sigval_t is still
defined by signal.h if __USE_MISC (reflecting the nonstandard nature
of that name).

Tested for x86_64.

	* signal/bits/types/__sigval_t.h: New file.
	* signal/Makefile (headers): Add bits/types/__sigval_t.h.

Joseph Myers 5047057ffa Allow abort PLT references in libc.so for SH. 
Given my patch
<https://gcc.gnu.org/ml/gcc-patches/2017-08/msg00965.html> for the
ICEs building a glibc string function test for SH, the testsuite can
build completely for SH with GCC 7 and mainline.  However, there is a
test failure that does not appear for GCC 6: check-localplt fails
because of an abort PLT reference in libc.so.

Given the lack of a trap insn pattern for SH, it seems unavoidable
that the compiler might sometimes generate abort calls, and such abort
calls (generated from __builtin_trap when there is no trap insn
pattern) will be unaffected by the normal mapping to __GI_abort for
calls within glibc.  Thus, this patch allows (but does not require) an
abort PLT reference in libc.so for SH.

Tested for sh4-linux-gnu with build-many-glibcs.py (GCC 7, with my
patch applied).

	* sysdeps/unix/sysv/linux/sh/localplt.data: Allow abort in
	libc.so.

Adhemerval Zanella 1f14d0c3dd posix: Fix mmap for m68k and ia64 (BZ#21908) 
Default semantic for mmap2 syscall is to take the offset in 4096-byte
units.  However m68k and ia64 mmap2 implementation take in the
configured pageunit units and for both architecture it can be
different values.

This patch fixes the m68k runtime discover of mmap2 offset unit
and adds the ia64 definition to find it at runtime.

Checked the basic tst-mmap and tst-mmap-offset on m68k (the system
is configured with 4k, so current code is already passing on this
system) and a sanity check on x86_64-linux-gnu (which should not be
affected by this change).  Sergei also states that ia64 loader now
work correctly with this change.

Remove enum __ptrace_flags along with the only constant it contains,
PTRACE_SEIZE_DEVEL, from Linux's sys/ptrace.h files.

This temporary development constant shouldn't have been added to

v3.1-rc1~308^2~28 as a temporary part of new experimental PTRACE_SEIZE
interface.  Later, as PTRACE_SEIZE stabilized and lost its experimental
status, this flag was removed from Linux by commit v3.4-rc1~109^2~20.

Joseph Myers 3d452dabd1 Fix uc_* namespace (bug 21457). 
The standard members of ucontext_t, in all standard versions with that
type, are uc_link, uc_sigmask, uc_stack and uc_mcontext.

The uc_* namespace is mostly reserved for additions to the structure.
However, in XPG4.2, it's only reserved when <ucontext.h> is included,
not when <signal.h> is included, while <signal.h> is required to
define ucontext_t (but not allowed to make visible other symbols from
<ucontext.h>).  Thus, nonstandard members should avoid uc_* names.
Some already do use __uc_*, but others don't; most architectures (all
except ia64, I think) have a member uc_flags and some have additional
members beyond that.

This patch makes nonstandard members have an __ prefix unless
__USE_MISC is defined.  Members whose names indicate they are solely
padding / reserved for future use are renamed unconditionally to use
the __glibc_reserved1 naming convention.

This is part of the preparation for a revised version of the
mcontext_t / sigcontext patch to be able to eliminate all 13 of the
miscellaneous XFAILs in conform/Makefile, rather than only 11 of them
as at present (at least one further fix on top of this one will be
needed for that as well).

Tested for x86_64, and with build-many-glibcs.py.

Siddhesh Poyarekar 36ada5f681 aarch64: Optimized memcpy for Qualcomm Falkor processor 
This is an optimized implementation of the memcpy routine that gives a
significant gain in performance for all sizes of copies on the
Qualcomm Falkor processor.  A detailed rationale of the implementation
is written in a comment in the patch.

This implementation improves time for copies up to 128 bytes by up to
15% and for larger copies by up to 35% in the glibc
microbenchmark. The memcpy-random benchmark sees improvements in all
sizes in the range of 13%-18%.

Here are the full numbers extracted from the glibc microbenchmark
using the commands:

Joseph Myers f17a42333f Do not use __ptr_t. 
sys/cdefs.h has a macro __ptr_t, which a few places in glibc use
instead of void *.  void * is a well-understood standard type for that
purpose and in a post-C89 context there is no need for a macro for it;
this patch changes those places to use void * directly instead.

Unlike __long_double_t, __ptr_t is widely used outside glibc (or at
least has many hits on codesearch.debian.net).  I don't know how many
of those uses would break if sys/cdefs.h ceased to define the macro,
but there's enough risk that this patch leaves the definition and just
removes the uses within glibc; removal of the definition can be
considered separately if desired.

H.J. Lu 086df229ee i386: Add <startup.h> [BZ #21913] 
On Linux/i386, there are 3 ways to make a system call:

1. call *%gs:SYSINFO_OFFSET.  This requires TLS initialization.
2. call *_dl_sysinfo.  This requires relocation of _dl_sysinfo.
3. int $0x80.  This is slower than #2 and #3, but works everywhere.

When an object file is compiled with PIC, #1 is prefered since it is
faster than #3 and doesn't require relocation of _dl_sysinfo.  For
dynamic executables, ld.so initializes TLS.  However, for static
executables, before TLS is initialized by __libc_setup_tls, #3 should
be used for system calls.

This patch adds <startup.h> which defines _startup_fatal and defaults
it to __libc_fatal.  It replaces __libc_fatal with _startup_fatal in
static executables where it is called before __libc_setup_tls is called.
This header file is included in all files containing functions which are
called before __libc_setup_tls is called.  On Linux/i386, when PIE is
enabled by default, _startup_fatal is turned into ABORT_INSTRUCTION and
I386_USE_SYSENTER is defined to 0 so that "int $0x80" is used for system
calls before __libc_setup_tls is called.

Tested on i686 and x86-64.  Without this patch, all statically-linked
tests will fail on i686 when the compiler defaults to -fPIE.

	* csu/libc-tls.c: Include <startup.h> first.

Adhemerval Zanella 852d631207 posix: Set p{read,write}v2 to return ENOTSUP (BZ#21780) 
Different than other architectures hppa-linux-gnu define different values
for ENOTSUP and EOPNOTSUPP, where the later is a Linux specific one.
This leads to tst-preadwritev{64}v2 tests failures:

$ ./testrun.sh misc/tst-preadvwritev2
error: tst-preadvwritev2-common.c:35: preadv2 failure did not set errno to ENOTSUP (223)
error: 1 test failures

The straightforward fix is to return the POSIX defined ENOTSUP on all
p{read,write}v{64}v2 implementations instead of Linux specific one.

Checked on x86_64-linux-gnu and the tst-preadwritev{64}v2 on
hppa-linux-gnu (although due the installed kernel on my testing system
the pwritev{64}v2 with an invalid flag still fails due a known kernel
issue [1]).

Joseph Myers cd65836b5f Fix XPG4.2 bits/sigaction.h namespace (bug 21899). 
For XPG4.2, sa_sigaction, SA_ONSTACK, SA_RESETHAND, SA_RESTART and
SA_NODEFER should be defined in signal.h, but they are only defined
for other standards at present.

This patch fixes the various bits/sigaction.h headers accordingly.
All the fixes are essentially the same, except those for SPARC and
Tile.

For SPARC, the header (a) spuriously defined various nonstandard
macros for __USE_UNIX98 || defined __USE_XOPEN2K8 and (b) defined some
standard macros as aliases of nonstandard ones instead of the other
way round.  This patch fixes the SPARC header to handle these macros
the same way and with the same conditions as those for other
architectures, so the standard macros are the primary ones and the
other ones are defined only for __USE_MISC and are aliases of the
standard ones where applicable.

For Tile, the header spuriously defined the nonstandard macro
SA_NOPTRACE for __USE_UNIX98 || defined __USE_XOPEN2K8; this is moved
to __USE_MISC.

(Those nonstandard macros are in a reserved namespace, but it seems
desirable to be consistent between architectures as far as possible,
and so not define them in standard modes anywhere.)

Tested for x86_64, and with build-many-glibcs.py.

Joseph Myers d9fee042e2 Consistently use uintN_t not u_intN_t everywhere. 
This patch changes the remaining uses of the old nonstandard u_intN_t
types in glibc to use the C99 uintN_t instead, except for the
definitions of those typedefs and the tests of them in the c++-types
test.  This follows the previous such fix for libm, and being
consistent in using uintN_t makes sense as a global cleanup.

is created for this branch, however for MicroBlaze R_MICROBLAZE_64_PCREL
type relocations symbols are not resolved. Additionally due to the
branch being located in the .text section the instruction cannot be
rewritten as the section is not writable, and causes a segfault at
runtime when loading libpthread.

To resolve this issue, ensure the branch is done using PLT. This removes
the need to modify the instruction and trades the R_MICROBLAZE_64_PCREL
for a more common R_MICROBLAZE_JUMP via the PLT.

	[BZ #21779]
	* sysdeps/unix/sysv/linux/microblaze/pt-vfork.S: Branch using PLT.

Adhemerval Zanella 95a7339258 tunables: Use direct syscall for access (BZ#21744) 
The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno.  It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector.  But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.

This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.

Dmitry V. Levin cab91f947a S390: fix sys/ptrace.h to make it includible again after asm/ptrace.h 
sys/ptrace.h on S390 used to be includible both before and after
asm/ptrace.h, until commit b08a6a0dea
among other changes introduced PTRACE_SINGLEBLOCK enum constant which
is also defined in asm/ptrace.h as a macro, making sys/ptrace.h fail
to compile when included after asm/ptrace.h.

* sysdeps/unix/sysv/linux/s390/sys/ptrace.h [_LINUX_PTRACE_H ||
_S390_PTRACE_H]: Undefine all PTRACE_* macro constants defined
later as enum constants, except PTRACE_PEEKUSER, PTRACE_POKEUSER,
and PTRACE_SEIZE_DEVEL that are not defined by Linux headers.

Tulio Magno Quites Machado Filho 91ac3a7d84 powerpc: Fix float128 IFUNC relocations [BZ #21707] 
The patch proposed by Peter Bergner [1] to libgcc in order to fix
[BZ #21707] adds a dependency on a symbol provided by the loader,
forcing the loader to be linked to tests after libgcc was linked.

It also requires to read the thread pointer during IRELA relocations.

Tested on powerpc, powerpc64, powerpc64le, s390x and x86_64.
