637461d965 Clean up kernel version conditionals for pre-2.6.32 kernels.
This patch does some initial cleanup, following the move to 2.6.32
minimum kernel version, by removing __LINUX_KERNEL_VERSION
conditionals that are now always-true or always-false.  In the case of
__ASSUME_ARG_MAX_STACK_BASED, where the conditional used a kernel
version that was itself in a macro, the associated sysconf.c code is
also cleaned up and __ASSUME_ARG_MAX_STACK_BASED removed completely.

Tested x86_64 that disassembly of installed shared libraries is
unchanged by the patch.

6d96f5e4c0 ARM: Remove lowlevellock.c
lowlevellock.c for arm differs from the generic lowlevellock.c only in
insignificant ways, so can be removed. Happily, this fixes BZ 15119
(unnecessary busy loop in __lll_timedlock_wait on arm).

The notable differences between the arm and generic implementations are:

1) arm __lll_timedlock_wait has a fast path out if futex has been set
to 0 between since the function was called. This seems unlikely to
happen very often, so it seems at worst harmless to lose this fast
path.

2) Some function in arm's lowlevellock.c set futex to 2 if it was 1.
The generic version always sets the futex to 2. As futex can only be
0, 1 or 2 on entry into these functions, the behaviour is equivalent.
(If the futex manages to be 0 on entry then we've just lost another
unlikely fast path out.)

There are no test suite regressions.

Note that hppa and sparc also have their own lowlevellock.c. I believe
hppa can also be removed, so I'll send a separate patch for that
shortly. sparc's seems to be genuinely needed as it uses a different
locking structure.

Also note that the analysis at
https://sourceware.org/ml/libc-ports/2013-02/msg00021.html indicates a
further locking performance bug to fix - I've got a partial patch for
that which I can submit once I've finished testing.

d0f5b3f851 Increase minimum Linux kernel version to 2.6.32.
This patch increases the minimum Linux kernel version for glibc to
2.6.32, as discussed in the thread starting at
<https://sourceware.org/ml/libc-alpha/2014-01/msg00511.html>.

This patch just does the minimal change to arch_minimum_kernel
settings (and LIBC_LINUX_VERSION, which determines the minimum kernel
headers version, as it doesn't make sense for that to be older than
the minimum kernel that can be used at runtime).  Followups would be
expected to do, roughly and not necessarily precisely in this order:

* Remove __LINUX_KERNEL_VERSION checks in kernel-features.h files
  where those checks are always true / always false for kernels 2.6.32
  and above.

* Otherwise simplify/improve conditionals in those files (for example,
  where defining once in the main file then undefining in
  architecture-specific files makes things clearer than having lots of
  separate definitions of the same macro), possibly fixing in the
  process cases where a macro should optimally have been defined for a
  given architecture but wasn't.  (In the review in preparation for
  this version increase I checked what the right conditions should be
  for all macros in the main kernel-features.h whose definitions there
  would have been affected by the increase - but I only fixed that
  subset of the issues found where --enable-kernel=2.6.32 would have
  caused a kernel feature to be wrongly assumed to be present, not any
  cases where a feature is not assumed but could be assumed.)

* Remove conditionals on __ASSUME_* where they can now be taken to be
  always-true, and the definitions when the macros are only used in
  Linux-specific files.

* Split more architectures out of the main kernel-features.h (like
  ex-ports architectures), once various of the architecture
  conditionals there have been eliminated so the new
  architecture-specific files are no larger than actually necessary.

Tested x86_64.

37d3500738 aarch64: Re-implement setcontext without rt_sigreturn syscall
The current implementation of setcontext uses rt_sigreturn to restore
the contents of registers. This contrasts with the way most other
architectures implement setcontext:

  powerpc64, mips, tile:

  Call rt_sigreturn if context was created by a call to a signal handler,
  otherwise restore in user code.

  powerpc32:

  Call swapcontext system call and don't call sigreturn or rt_sigreturn.

  x86_64, sparc, hppa, sh, ia64, m68k, s390, arm:

  Only support restoring "synchronous" contexts, that is contexts
  created by getcontext, and restoring in user code and don't call
  sigreturn or rt_sigreturn.

  alpha:

  Call sigreturn (but not rt_sigreturn) in all cases to do the restore.

The text of the setcontext manpage suggests that the requirement to be
able to restore a signal handler created context has been dropped from
SUSv2:

  If  the context was obtained by a call to a signal handler, then old
  standard text says that "program execution continues with the program
  instruction following the instruction interrupted by the signal".
  However, this sentence was removed in SUSv2, and the present verdict
  is "the result is unspecified".

Implementing setcontext by calling rt_sigreturn unconditionally causes
problems when used with sigaltstack as in BZ #16629. On this basis it
seems that aarch64 is broken and that new ports should only support
restoring contexts created with getcontext and do not need to call
rt_sigreturn at all.

This patch re-implements the aarch64 setcontext function to restore
the context in user code in a similar manner to x86_64 and other ports.

ChangeLog:

7ffa942302 PowerPC: define _CALL_ELF if compiler does not
This patch makes the configure adds -D_CALL_ELF=1 when compiler does
not define _CALL_ELF (versions before powerpc64le support).  It cleans
up compiler warnings on old compiler where _CALL_ELF is not defined
on powerpc64(be) builds.

It does by add a new config.make variable for configure-deduced
CPPFLAGS and accumulate into that (confix-extra-cppflags).  It also
generalizes libc_extra_cflags so it accumulates in sysdeps configure
fragmenets.

47c5adebd2 Correct robust mutex / PI futex kernel assumptions (bug 9894).
This patch continues fixing __ASSUME_* issues in preparation for
moving to a 2.6.32 minimum kernel version by addressing assumptions on
robust mutex and PI futex support availability.  Those assumptions are
bug 9894, but to be clear this patch does not address all the issues
from that bug about wrong version assumptions, only those still
applicable for --enable-kernel=2.6.32 or later (with the expectation
that the move to that minimum kernel will obsolete the other parts of
the bug).  The patch is independent of
<https://sourceware.org/ml/libc-alpha/2014-03/msg00585.html>, my other
pending-review patch preparing for the kernel version change; the two
together complete all the changes I believe are needed in preparation
regarding any macro in sysdeps/unix/sysv/linux/kernel-features.h that
would be affected by such a change.  (I have not checked the
correctness of macros whose conditions are unaffected by such a
change, or macros only defined in other kernel-features.h files.)

As discussed in that bug, robust mutexes and PI futexes need
futex_atomic_cmpxchg_inatomic to be implemented, in addition to
certain syscalls needed for robust mutexes (and
architecture-independent kernel pieces for all the features in
question).  That is, as I understand it, they need
futex_atomic_cmpxchg_inatomic to *work* (not return an ENOSYS error).

The issues identified in my analysis relate to ARM, M68K, MicroBlaze,
MIPS and SPARC.

On ARM, whether futex_atomic_cmpxchg_inatomic works depends on the
kernel configuration.  As of 3.13, the condition for *not* working is
CONFIG_CPU_USE_DOMAINS && CONFIG_SMP.  As of 2.6.32 it was simply
CONFIG_SMP that meant the feature was not implemented.  I don't know
if there are any circumstances in which we can say "we can assume a
userspace glibc binary built with these options will never run on a
kernel with the problematic configuration", but at least for now I'm
just undefining the relevant __ASSUME_* macros for ARM.

On M68K, two of the three macros are undefined for kernels before
3.10, but as far as I can see __ASSUME_FUTEX_LOCK_PI is in the same
group needing futex_atomic_cmpxchg_inatomic support and so should be
undefined as well.

On MicroBlaze the required support was added in 2.6.33.

On MIPS, the support depends on cpu_has_llsc in the kernel - that is,
actual hardware LL/SC support (GCC and glibc for MIPS GNU/Linux rely
on the instructions being supported in some way, but it may be kernel
emulation; futex_atomic_cmpxchg_inatomic doesn't work with that
emulation).  The same condition as in GCC for indicating LL/SC support
may not be available is used for undefining the macros in glibc,
__mips == 1 || defined _MIPS_ARCH_R5900.  (Maybe we could in fact
desupport MIPS processors without the hardware support in glibc.)

On SPARC, 32-bit kernels don't support futex_atomic_cmpxchg_inatomic;
__arch64__ || __sparc_v9__ is used as the condition for binaries that
won't run on 32-bit kernels.

This patch is not tested beyond the sanity check of an x86_64 build.

d7a68734f7 Fix futimesat for older MicroBlaze kernels (bug 16648).
Continuing the fixes for __ASSUME_* issues in preparation for moving
to a 2.6.32 minimum kernel version, this *untested* patch fixes bug
16648, the definition of __ASSUME_ATFCTS meaning that the futimesat
syscall is assumed for all MicroBlaze kernels despite not being
present until 2.6.33.

__ASSUME_ATFCTS controls conditionals relating to a lot of different
syscalls in Linux-specific code (fstatat64 faccessat fchmodat fchownat
futimesat newfstatat linkat mkdirat openat readlinkat renameat
symlinkat unlinkat mknodat), where whether newfstatat fstatat64
futimesat are used depends on the architecture, as well as controlling
whether openat64_not_cancel_3 is expected to work in
sysdeps/posix/getcwd.c.  The assumptions are all OK as of 2.6.32
except for this MicroBlaze case, and it's generally desirable to get
rid of as many of the __ASSUME_ATFCTS conditionals as possible, to
simplify the code (the fallbacks include potential unbounded dynamic
stack allocations).  Thus, rather than the simplest approach of
undefining __ASSUME_ATFCTS for older kernels on MicroBlaze, this patch
takes the approach of using the linux-generic implementation of
futimesat for MicroBlaze kernels before 2.6.33 (all such kernels have
the utimensat syscall).

1ca2d03e3e Fix -Wundef warnings for _ABI* on MIPS.
This patch fixes -Wundef warnings related to the _ABI* macros on MIPS.
GCC predefines only the _ABI* macro related to the ABI actually in
use, meaning that a conditional such as "#if _MIPS_SIM == _ABI64" is
true only for the ABI in question (all the macros are nonzero), but
produces a -Wundef warning for the other ABIs.  The normal approach to
using these macros is to include <sgidefs.h>, which ensures that all
three _ABI* macros are defined rather than just one; this patch does
so in the places that caused warnings (the bulk of the warnings
arising from <bits/wordsize.h>).  Tested that the warnings are fixed.

This patch makes the MicroBlaze kernel-features.h undefine
__ASSUME_PSELECT.  I'd also encourage wiring it up in the kernel (so
you can then make this #undef conditional, and eventually obsolete
once a recent-enough kernel is required).  I suspect it wasn't wired
up because of the mistaken comment in asm/unistd.h "obsolete ->
sys_pselect7" (there is no such syscall as pselect7).

5c7808498e Fix POSIX namespace for <bits/siginfo.h> (bug 16674).
<bits/siginfo.h> causes symbols ILL_*, FPE_*, SEGV_* BUS_*, CLD_*,
POLL_* and TRAP_* to be exposed in <signal.h> (and <sys/wait.h>), even
though those symbols are not in non-XSI POSIX before POSIX.1-2008 and
even in POSIX.1-2008 the TRAP_* symbols are XSI-only.  This patch
conditions the symbols appropriately in the various <bits/siginfo.h>
implementations (various <signal.h> and <sys/wait.h> conformtest
issues remain for standards other than POSIX (1995/6)).  Tested
x86_64.

67737b8f07 Don't define __ASSUME_UTIMES for linux-generic architectures.
The __ASSUME_UTIMES macro describes whether the utimes syscall is
present.  For linux-generic architectures, it isn't (utimensat is
instead), so the macro should not be defined for them; this patch
removes the spurious definitions for such architectures.  (Those
definitions don't actually cause any user-visible bug, because
futimes.c doesn't use __ASSUME_UTIMES if __ASSUME_UTIMENSAT is
defined, and futimesat.c and utimes.c are overridden for
linux-generic, but the definitions are still logically incorrect.)

acd7f096d7 Complete _BSD_SOURCE / _SVID_source followup cleanup.
This patch completes the headers cleanup consequent on removal of
_BSD_SOURCE and _SVID_SOURCE (apart from any subsequent deprecations):

* #endif conditionals that referred to BSD or SVID are updated.

* Redundant __USE_* tests in cases involving __USE_MISC are removed.
  This includes cases such as __USE_MISC || __USE_ISOC99, where
  __USE_MISC is redundant (because __USE_MISC is only ever defined in
  the default / _DEFAULT_SOURCE / _GNU_SOURCE case, when __USE_ISOC99
  is also defined; the same applies to the non-XSI-extended POSIX
  versions), and cases involving __USE_GNU, where __USE_GNU is
  redundant (because if __USE_GNU is defined, so are the other __USE_*
  macros).  There may well be other cases of __USE_FOO || __USE_BAR
  tests that could be simplified because one macro implies the other;
  this patch only addresses cases involving __USE_MISC.

bc688c1029 Fix __ASSUME_SENDMMSG issues (bug 16611).
Similar to the issues for accept4 and recvmmsg, __ASSUME_SENDMMSG is
also confused about whether it relates to function availability or
socketcall operation availability, and the conditions for the
definition are always wrong (sendmmsg appeared in Linux kernel 3.0,
not 2.6.39); this is now bug 16611.

This patch splits the macro into separate macros like those for
accept4 and recvmmsg, defining them for appropriate kernel versions.

Tested x86_64, including that disassembly of the installed shared
libraries is unchanged by this patch.

0e31b18ca2 Fix __ASSUME_RECVMMSG issues (bug 16610).
Similar to the issues for accept4, __ASSUME_RECVMMSG is also confused
about whether it relates to function availability or socketcall
operation availability; this is now bug 16610.

Nothing actually tests __ASSUME_RECVMMSG for function availability,
but implicit in the definition in kernel-features.h is the idea that
it makes sense when the syscall is available and socketcall is not
being used.  As with accept4, there are architectures where the
syscall was added later than the socketcall operation, meaning that
assuming glibc is built with recent enough kernel headers, it does not
attempt to use socketcall for these operations and __ASSUME_RECVMMSG
gets defined for kernels >= 2.6.33 even when the syscall was only
added later.

This patch splits the macro into separate macros like those used for
accept4; having similar macro structure in both cases (and for
sendmmsg once I've dealt with that) seems likely to be less confusing
than having a different structure on the basis of nothing actually
needing to assume the recvmmsg function works.  Appropriate
definitions are added for all architectures.

Architecture-specific note: Tile's kernel-features.h says "TILE glibc
support starts with 2.6.36", which is accurate in that 2.6.36 was the
first kernel version with Tile support, and on that basis I've made
that header define __ASSUME_RECVMMSG_SYSCALL unconditionally.
However, Tile's configure.ac has arch_minimum_kernel=2.6.32.  Since
arch_minimum_kernel is meant to reflect only kernel.org kernel
versions, I think that should change to 2.6.36.  (If using glibc with
kernel versions from before a port went in kernel.org, it's your
responsibility to change arch_minimum_kernel in a local patch, and at
the same time to adjust any __ASSUME_* definitions that may not be
correct for your older kernel; for developing the official glibc it
should only ever be necessary to consider what official kernel.org
releases support.)

Tested x86_64, including that disassembly of the installed shared
libraries is unchanged by this patch.

dd481ccffd Fix __ASSUME_ACCEPT4 issues (bug 16609).
In <https://sourceware.org/ml/libc-alpha/2013-12/msg00008.html>,
Aurelien noted issues with the definition of __ASSUME_ACCEPT4, which I
discussed in more detail in
<https://sourceware.org/ml/libc-alpha/2013-12/msg00014.html>; these
are now bug 16609.

As previously noted, __ASSUME_ACCEPT4 is used in two ways:

* In OS-independent code, to mean "accept4 can be assumed to work
  rather than fail with ENOSYS".  It doesn't matter whether it's
  implemented with socketcall or a separate syscall.

* In Linux-specific code, to mean "the socketcall multiplex syscall
  can be assumed to handle the accept4 operation.  When used in
  Linux-specific code, it *never* refers to anything relating to the
  accept4 syscall, only to the socketcall multiplexer.

This patch splits the macro into separate __ASSUME_ACCEPT4_SOCKETCALL,
__ASSUME_ACCEPT4_SYSCALL and __ASSUME_ACCEPT4 to clarify the different
cases involved.  A macro __ASSUME_SOCKETCALL is added for convenience
in writing logic relating to all socketcall architectures.  In
addition, to address the issue of architectures where socketcall
support for accept4 was added before a separate syscall was added (and
so the separate syscall should not be used unless known to be present
or fallback to socketcall is available), a fourth macro
__ASSUME_ACCEPT4_SYSCALL_WITH_SOCKETCALL is added to indicate that the
syscall became available at the same time as socketcall support.  This
is then used in the relevant places in a conditional determining
whether to undefine __NR_accept4 (the simple approach to avoiding the
syscall's presence causing problems; I didn't try to implement runtime
fallback from the syscall to socketcall).

Architecture-specific note: alpha defined __ASSUME_ACCEPT4 for 2.6.33
and later, but actually the syscall was added for alpha in 3.2, so
this patch uses the correct condition for __ASSUME_ACCEPT4_SYSCALL
there.

Tested x86_64, including that disassembly of the installed shared
libraries is unchanged by this patch.

498afc54df Combine __USE_BSD and __USE_SVID into __USE_MISC.
This patch cleans up following the obsoletion of _BSD_SOURCE and
_SVID_SOURCE by combining __USE_BSD and __USE_SVID into __USE_MISC.

The only non-mechanical part of this patch is the changes to
features.h; everything else is simple substitution of __USE_MISC for
the old macros.  Thus, this patch leaves obviously redundant
conditionals such as "defined __USE_MISC || defined __USE_MISC", and
does not update #endif comments where they referred to BSD or SVID in
words instead of the literal macro name.  This is intended to
facilitate patch review by separating the less mechanical changes from
these purely mechanical changes into a separate patch.  (I do intend
to integrate all the changes from
<https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I
believe includes all the trailing comment updates, in subsequent
patches.)

f877c4f2bf Fix tst-setgetname for Linux kernels < 2.6.33.
Support for /proc/self/task/$tid/comm as added in Linux 2.6.33,
therefore since the test tst-setgetname relies on this functionality
to operate we must skip the test in kernels < 2.6.33. We wrap the
checks with __ASSUME_PROC_PID_TASK_COMM such that in the future when
we move arch_minimum_kernel to 2.6.33 we can remove this code.

d98720e07f PowerPC: Fix gettimeofday ifunc selection
The IFUNC selector for gettimeofday runs before _libc_vdso_platform_setup where
__vdso_gettimeofday is set. The selector then sets __gettimeofday (the internal
version used within GLIBC) to use the system call version instead of the vDSO one.
This patch changes the check if vDSO is available to get its value directly
instead of rely on __vdso_gettimeofday.

This patch changes it by getting the vDSO value directly.

It fixes BZ#16431.

736c304a1a PowerPC: Fix ftime gettimeofday internal call returning bogus data
This patches fixes BZ#16430 by setting a different symbol for internal
GLIBC calls that points to ifunc resolvers. For PPC32, if the symbol
is defined as hidden (which is the case for gettimeofday and time) the
compiler will create local branches (symbol@local) and linker will not
create PLT calls (required for IFUNC). This will leads to internal symbol
calling the IFUNC resolver instead of the resolved symbol.
For PPC64 this behavior does not occur because a call to a function in
another translation unit might use a different toc pointer thus requiring
a PLT call.

ef7344f09c Flatten sysdeps/unix/bsd/bsd4.4 into sysdeps/unix/bsd.
As discussed in
<https://sourceware.org/ml/libc-alpha/2012-04/msg00840.html> and
<https://sourceware.org/ml/libc-alpha/2012-04/msg00989.html>, it seems
appropriate to flatten sysdeps/unix/bsd/bsd4.4 into sysdeps/unix/bsd.

The bulk of the patch is just moving files.  The only other changes
are: update paths in sysdeps/mach/hurd/Implies and
sysdeps/unix/sysv/linux/wait3.c; merge the two syscalls.list files,
with the removal of syscalls that were in
sysdeps/unix/bsd/syscalls.list but overridden in the bsd4.4 directory
by .c files there.

Tested x86_64.  The installed shared libraries are identical before
and after the patch except for libc.so where the move of wait3.c
(included by sysdeps/unix/sysv/linux/wait3.c) affects debug info, but
the disassembly is unchanged.

5b118558f9 PowerPC64 ELFv2 ABI 6/6: Bump ld.so soname version number
To avoid having a ELFv2 binary accidentally picking up an old ABI ld.so,
this patch bumps the soname to ld64.so.2.

In theory (or for testing purposes) this will also allow co-installing
ld.so versions for both ABIs on the same system.  Note that the kernel
will already be able to load executables of both ABIs.  However, there
is currently no plan to use that theoretical possibility in a any
supported distribution environment ...

Note that in order to check which ABI to use, we need to invoke the
compiler to check the _CALL_ELF macro; this is done in a new configure
check in sysdeps/unix/sysv/linux/powerpc/powerpc64/configure.ac,
replacing the hard-coded value of default-abi in the Makefile.

8b8a692cfd PowerPC64 ELFv2 ABI 4/6: Stack frame layout changes
This updates glibc for the changes in the ELFv2 relating to the
stack frame layout.  These are described in more detail here:
http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01149.html
http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01146.html

Specifically, the "compiler and linker doublewords" were removed,
which has the effect that the save slot for the TOC register is
now at offset 24 rather than 40 to the stack pointer.

In addition, a function may now no longer necessarily assume that
its caller has set up a 64-byte register save area its use.

To address the first change, the patch goes through all assembler
files and replaces immediate offsets in instructions accessing the
ABI-defined stack slots by symbolic offsets.  Those already were
defined in ucontext_i.sym and used in some of the context routines,
but that doesn't really seem like the right place for those defines.

The patch instead defines those symbolic offsets in sysdeps.h,
in two variants for the old and new ABI, and uses them systematically
in all assembler files, not just the context routines.

The second change only affected a few assembler files that used
the save area to temporarily store some registers.  In those
cases where this happens within a leaf function, this patch
changes the code to store those registers to the "red zone"
below the stack pointer.  Otherwise, the functions already allocate
a stack frame, and the patch changes them to add extra space in
these frames as temporary space for the ELFv2 ABI.

696caf1d00 PowerPC64 ELFv2 ABI 2/6: Remove function descriptors
This patch adds support for the ELFv2 ABI feature to remove function
descriptors.  See this GCC patch for in-depth discussion:
http://gcc.gnu.org/ml/gcc-patches/2013-11/msg01141.html

This mostly involves two types of changes: updating assembler source
files to the new logic, and updating the dynamic loader.

After the refactoring in the previous patch, most of the assembler source
changes can be handled simply by providing ELFv2 versions of the
macros in sysdep.h.   One somewhat non-obvious change is in __GI__setjmp:
this used to "fall through" to the immediately following __setjmp ENTRY
point.  This is no longer safe in the ELFv2 since ENTRY defines both
a global and a local entry point, and you cannot simply fall through
to a global entry point as it requires r12 to be set up.

Also, makecontext needs to be updated to set up registers according to
the new ABI for calling into the context's start routine.

The dynamic linker changes mostly consist of removing special code
to handle function descriptors.  We also need to support the new PLT
and glink format used by the the ELFv2 linker, see:
https://sourceware.org/ml/binutils/2013-10/msg00376.html

In addition, the dynamic linker now verifies that the dynamic libraries
it loads match its own ABI.

The hack in VDSO_IFUNC_RET to "synthesize" a function descriptor
for vDSO routines is also no longer necessary for ELFv2.

d31beafa8e PowerPC64 ELFv2 ABI 1/6: Code refactoring
This is the first patch to support the new ELFv2 ABI in glibc.

As preparation, this patch simply refactors some of the powerpc64 assembler
code to move all code related to creating function descriptors (.opd section)
or using function descriptors (function pointer call) into a central place
in sysdep.h.

Note that most locations creating .opd entries were already using macros
in sysdep.h, this patch simply extends this to the remaining places.

No relevant change in generated code expected.

5162e7dd96 PowerPC64: Fix incorrect CFI in *context routines
The context established by "makecontext" has a link register pointing
back to an error path within the makecontext routine.  This is currently
covered by the CFI FDE for makecontext itself, which is simply wrong
for the stack frame *inside* the context.  When trying to unwind (e.g.
doing a backtrace) in a routine inside a context created by makecontext,
this can lead to uninitialized stack slots being accessed, causing the
unwinder to crash in the worst case.

Similarly, during parts of the "setcontext" routine, when the stack
pointer has already been switched to point to the new context, the
address range is still covered by the CFI FDE for setcontext.  When
trying to unwind in that situation (e.g. backtrace from an async
signal handler for profiling), it is again possible that the unwinder
crashes.

Theses are all problems in existing code, but the changes in stack
frame layout appear to make the "worst case" much more likely in
the ELFv2 ABI context.  This causes regressions e.g. in the libgo
testsuite on ELFv2.

This patch fixes this by ending the makecontext/setcontext FDEs
before those problematic parts of the assembler, similar to what
is already done on other platforms.   This fixes the libgo
regression on ELFv2.

f7c399cff5 PowerPC SIGSTKSZ
http://sourceware.org/ml/libc-alpha/2013-08/msg00093.html

This copies the sparc version of sigstack.h, which gives powerpc
 #define MINSIGSTKSZ     4096
 #define SIGSTKSZ        16384

Before the VSX changes, struct rt_sigframe size was 1920 plus 128 for
__SIGNAL_FRAMESIZE giving ppc64 exactly the default MINSIGSTKSZ of
2048.

After VSX, ucontext increased by 256 bytes.  Oops, we're over
MINSIGSTKSZ, so powerpc has been using the wrong value for quite a
while.  Add another ucontext for TM and rt_sigframe is now at 3872,
giving actual MINSIGSTKSZ of 4000.

The glibc testcase that I was looking at was tst-cancel21, which
allocates 2*SIGSTKSZ (not because the test is trying to be
conservative, but because the test actually has nested signal stack
frames).  We blew the allocation by 48 bytes when using current
mainline gcc to compile glibc (le ppc64).

The required stack depth in _dl_lookup_symbol_x from the top of the
next signal frame was 10944 bytes.  I guess you'd want to add 288 to
that, implying an actual SIGSTKSZ of 11232.

e4608715e6 CVE-2013-2207, BZ #15755: Disable pt_chown.
The helper binary pt_chown tricked into granting access to another
user's pseudo-terminal.

Pre-conditions for the attack:

 * Attacker with local user account
 * Kernel with FUSE support
 * "user_allow_other" in /etc/fuse.conf
 * Victim with allocated slave in /dev/pts

Using the setuid installed pt_chown and a weak check on whether a file
descriptor is a tty, an attacker could fake a pty check using FUSE and
trick pt_chown to grant ownership of a pty descriptor that the current
user does not own.  It cannot access /dev/pts/ptmx however.

In most modern distributions pt_chown is not needed because devpts
is enabled by default. The fix for this CVE is to disable building
and using pt_chown by default. We still provide a configure option
to enable hte use of pt_chown but distributions do so at their own
risk.

d7e06450b9 BZ #15711: Avoid circular dependency for syscall.h
The generated header is compiled with `-ffreestanding' to avoid any
circular dependencies against the installed implementation headers.
Such a dependency would require the implementation header to be
installed before the generated header could be built (See bug 15711).
In current practice the generated header dependencies do not include
any of the implementation headers removed by the use of `-ffreestanding'.

5c95f7b66b S/390: Change struct statfs[64] member types to unsigned values
Kay Sievers reported that coreutils' stat tool has a problem with
s390's statfs[64] definition:

> The definition of struct statfs::f_type needs a fix. s390 is the only
> architecture in the kernel that uses an int and expects magic
> constants lager than INT_MAX to fit into.
>
> A fix is needed to make Fedora boot on s390, it currently fails to do
> so. Userspace does not want to add code to paper-over this issue.

[...]

> Even coreutils cannot handle it:
>   #define RAMFS_MAGIC  0x858458f6
>   # stat -f -c%t /
>   ffffffff858458f6
>
>   #define BTRFS_SUPER_MAGIC 0x9123683E
>   # stat -f -c%t /mnt
>   ffffffff9123683e

The bug is caused by an implicit sign extension within the stat tool:

out_uint_x (pformat, prefix_len, statfsbuf->f_type);

where the format finally will be "%lx".
A similar problem can be found in the 'tail' tool.
s390 is the only architecture which has an int type f_type member in
struct statfs[64]. Other architectures have either unsigned ints or
long values, so that the problem doesn't occur there.

Therefore change the type of the f_type member to unsigned int, so
that we get zero extension instead sign extension when assignment to
a long value happens.

d755bba40f Preserve errno across _PC_CHOWN_RESTRICTED call on XFS
Fix BZ #15305.

On kernel versions earlier than 2.6.29, the Linux kernel exported a
sysctl called restrict_chown for xfs, which could be used to allow
chown to users other than the owner.  2.6.29 removed this support,
causing the open_not_cancel_2 to fail and thus modify errno.  The fix
is to save and restore errno so that the caller sees it as unmodified.

Additionally, since the code to check the sysctl is not useful on
newer kernels, we add an ifdef so that in future the code block gets
rmeoved completely.

This is to overcome the possible complication of destructors of
thread_local objects getting called after the DSO in which they're

'unloadable' if it has a constructed thread_local object and marked as

In order for the __kernel_get_tbfreq vDSO call to work the
INTERNAL_VSYSCALL_NCS macro needed to be updated to prevent it from
assuming an integer return type (since the timebase frequency is a 64-bit
value) by specifying the type of the return type as a macro parameter.  The
macro then specifically declares the return value as a 'register' (or
implied pair) of the denoted type.  The compiler is then informed that this
register (or implied pair) is to be used for the return value.

9fab36eb58 Shrink heap on linux when overcommit_memory == 2
Using madvise with MADV_DONTNEED to release memory back to the kernel
is not sufficient to change the commit charge accounted against the
process on Linux.  It is OK however, when overcommit is enabled or is
heuristic.  However, when overcommit is restricted to a percentage of
memory setting the contents of /proc/sys/vm/overcommit_memory as 2, it
makes a difference since memory requests will fail.  Hence, we do what
we do with secure exec binaries, which is to call mmap on the region
to be dropped with MAP_FIXED. This internally unmaps the pages in
question and reduces the amount of memory accounted against the
process.

1214ec8f4c tst-getcpu: decode errno when sched_getcpu fails
The tst-getcpu test is failing on ia64 platforms due to sched_getcpu
returning an error.  But the current test only considers -1 when it's
also ENOSYS.  Tweak the logic a bit to make the output clearer.
