d2dc5467c6 Filter out NPTL internal signals (BZ #22391)
This patch filters out the internal NPTL signals (SIGCANCEL/SIGTIMER and
SIGSETXID) from signal functions.  GLIBC on Linux requires both signals to
proper implement pthread cancellation, posix timers, and set*id posix
thread synchronization.

And not filtering out the internal signal is troublesome:

  - A conformant program on a architecture that does not filter out the
    signals might inadvertently disable pthread asynchronous cancellation,
    set*id synchronization or posix timers.

  - It might also to security issues if SIGSETXID is masked and set*id
    functions are called (some threads might have effective user or group
    id different from the rest).

The changes are basically:

  - Change __is_internal_signal to bool and used on all signal function
    that has a signal number as input.  Also for signal function which accepts
    signals sets (sigset_t) it assumes that canonical function were used to
    add/remove signals which lead to some input simplification.

  - Fix tst-sigset.c to avoid check for SIGCANCEL/SIGTIMER and SIGSETXID.
    It is rewritten to check each signal indidually and to check realtime
    signals using canonical macros.

  - Add generic __clear_internal_signals and __is_internal_signal
    version since both symbols are used on generic implementations.

  - Remove superflous sysdeps/nptl/sigfillset.c.

  - Remove superflous SIGTIMER handling on Linux __is_internal_signal
    since it is the same of SIGCANCEL.

  - Remove dangling define and obvious comment on nptl/sigaction.c.

Checked on x86_64-linux-gnu.

e88ecbbfe8 [PATCH 7/7] sin/cos slow paths: refactor sincos implementation
Refactor the sincos implementation - rather than rely on odd partial inlining
of preprocessed portions from sin and cos, explicitly write out the cases.
This makes sincos much easier to maintain and provides an additional 16-20%
speedup between 0 and 2^27.  The overall speedup of sincos is 48% over this range.
Between 0 and PI it is 66% faster.

	(__cos): Likewise.
	* sysdeps/ieee754/dbl-64/s_sin.c (__sincos): Refactor using the same

aef3e2558a [PATCH 6/7] sin/cos slow paths: refactor duplicated code into dosin
Refactor duplicated code into do_sin.  Since all calls to do_sin use copysign to
set the sign of the result, move it inside do_sin.  Small inputs use a separate
polynomial, so move this into do_sin as well (the check is based on the more
conservative case when doing large range reduction, but could be relaxed).

	* sysdeps/ieee754/dbl-64/s_sin.c (do_sin): Use TAYLOR_SIN for small
	inputs.  Return correct sign.
	(do_sincos): Remove small input check before do_sin, let do_sin set
	the sign.

d9469deb14 [PATCH 3/7] sin/cos slow paths: remove slow paths from small range reduction
This patch improves the accuracy of the range reduction.  When the input is
large (2^27) and very close to a multiple of PI/2, using 110 bits of PI is not
enough.  Improve range reduction accuracy to 136 bits.  As a result the special
checks for results close to zero can be removed.  The ULP of the polynomials is
at worst 0.55ULP, so there is no reason for the slow functions, and they can be
removed.

	* sysdeps/ieee754/dbl-64/s_sin.c (reduce_sincos_1): Rename to
	reduce_sincos, improve accuracy to 136 bits.
	(do_sincos_1): Rename to do_sincos, remove fallbacks to slow functions.

7a5640f23a [PATCH 2/7] sin/cos slow paths: remove large range reduction
This patch removes the large range reduction code and defers to the huge range
reduction code.  The first level range reducer supports inputs up to 2^27,
which is way too large given that inputs for sin/cos are typically small
(< 10), and optimizing for a smaller range would give a significant speedup.

Input values above 2^27 are practically never used, so there is no reason for
supporting range reduction between 2^27 and 2^48.  Removing it significantly
simplifies code and enables further speedups.  There is about a 2.3x slowdown
in this range due to __branred being extremely slow  (a better algorithm could
easily more than double performance).

	* sysdeps/ieee754/dbl-64/s_sin.c (reduce_sincos_2): Remove function.
	(do_sincos_2): Likewise.

19a8b9a300 [PATCH 1/7] sin/cos slow paths: avoid slow paths for small inputs
This series of patches removes the slow patchs from sin, cos and sincos.
Besides greatly simplifying the implementation, the new version is also much
faster for inputs up to PI (41% faster) and for large inputs needing range
reduction (27% faster).

ULP is ~0.55 with no errors found after testing 1.6 billion inputs across most
of the range with mpsin and mpcos.  The number of incorrectly rounded results
(ie. ULP >0.5) is at most ~2750 per million inputs between 0.125 and 0.5,
the average is ~850 per million between 0 and PI.

Tested on AArch64 and x86_64 with no regressions.

The first patch removes the slow paths for the cases where the input is small
and doesn't require range reduction.  Update ULP tables for sin, cos and sincos
on AArch64 and x86_64.

	* sysdeps/aarch64/libm-test-ulps: Update ULP for sin, cos, sincos.
	* sysdeps/ieee754/dbl-64/s_sin.c (__sin): Remove slow paths for small
	inputs.
	(__cos): Likewise.
	* sysdeps/x86_64/fpu/libm-test-ulps: Update ULP for sin, cos, sincos.

8e4754ed7e Assume O_DIRECTORY for opendir
This patch assumes O_DIRECTORY works as defined by POSIX on opendir
implementation (aligning with other glibc code, for instance pwd).  This
allows remove both the fallback code to handle system with missing or
broken O_DIRECTORY along with the Linux specific opendir.c which just
advertise the working flag.

d39c0a459e sparc: Fix arch_fork definition
This patch fixes 3dc214977 for sparc.  Different than other architectures
SPARC kernel Kconfig does not define CONFIG_CLONE_BACKWARDS, however it
has the same ABI as if it did, implemented by sparc-specific code
(sparc_do_fork).

It also has a unique return value convention for clone:

   Parent -->  %o0 == child's  pid, %o1 == 0
   Child  -->  %o0 == parent's pid, %o1 == 1

Which required a special macro to correct issue the syscall
(INLINE_CLONE_SYSCALL).

Checked on sparc64-linux-gnu and sparcv9-linux-gnu.

	* sysdeps/unix/sysv/linux/arch-fork.h [__ASSUME_CLONE_BACKWARDS]

5f45f96ad0 Unify umount function implementations (bug 16552).
Linux kernel architectures have various arrangements for umount
syscalls.  There is a syscall that takes flags, and an older one that
does not.  Newer architectures have only the one taking flags, under
the name umount2 (or under the name umount, in the ia64 case).  Older
architectures may have both, under the names umount2 and umount (or
under the names umount and oldumount, in the alpha case).  glibc then
has several similar implementations of the umount function (no flags)
in terms of either the __umount2 function, or the corresponding
syscall, or in terms of the old syscall under either of its names.

This patch simplifies the implementations in glibc by always using the
__umount2 function to implement the umount function on all systems
using the Linux kernel.  The linux/generic implementation is moved to
sysdeps/unix/sysv/linux (without any changes to code or comments) and
all the other variants are removed.  (This will have the effect of
causing the new syscall to be used in some cases that previously used
the old one, but as discussed for previous changes, such a change to
the underlying syscalls used is OK.)

There remain two variants of how the __umount2 function is
implemented, either in umount2.S, or, for ia64, in syscalls.list.

Tested with build-many-glibcs.py.
