BZ#17460: Fix buffer overrun in nscd --help.
Don't use INTUSE with __adjtimex (bug 14132).

Bug 14132 is removal of the old INTDEF/INTUSE system of *_internal
aliases as obsoleted by the hidden_proto / hidden_def system.  Various
cases were cleaned up in 2012, but some remain.  This patch removes
the use of this mechanism for __adjtimex.

Tested for x86_64 that stripped installed shared libraries are
unchanged by the patch.

soft-fp: Remove FP_CLEAR_EXCEPTIONS.

As noted in
<https://sourceware.org/ml/libc-alpha/2013-10/msg00516.html>, the
soft-fp macro FP_CLEAR_EXCEPTIONS should not be necessary, as soft-fp
code should never set an exception and later clear it.

In fact, all four uses in glibc (for SPARC) are indeed unnecessary:
they appear in files that convert 32-bit or 64-bit integers to IEEE
binary128, an operation that can never raise any exceptions.  If this
was intended to enable the compiler to optimize away any FP_FROM_INT
code testing for exceptional cases, we now have a better way of doing
this: defining FP_NO_EXCEPTIONS before including soft-fp.h causes all
code handling exceptions to be stubbed out, and the rounding mode to
be hardwired for round-to-zero, to allow such optimizations for source
files where (a) the operation in question, for the particular types in
question, can never raise exceptions, but (b) some instances of the
operation for other types can, so the macros used in the file do
contain references to rounding or exceptions, albeit dead in that
particular file.

The uses in the Linux kernel are also unnecessary (clearing exceptions
at a point where they are already cleared).

This patch duly removes FP_CLEAR_EXCEPTIONS, making the SPARC code in
question use FP_NO_EXCEPTIONS and stop using exception-related macros.

	* soft-fp/soft-fp.h (FP_CLEAR_EXCEPTIONS): Remove macro.
	* sysdeps/sparc/sparc32/soft-fp/q_itoq.c: Define FP_NO_EXCEPTIONS.

	(_Q_utoq): Do not use FP_DECL_EX, FP_CLEAR_EXCEPTIONS or

soft-fp: Make extensions of subnormals from XFmode to TFmode signal underflow if traps enabled.

This patch fixes a soft-fp corner case I previously noted in
<https://sourceware.org/ml/libc-alpha/2013-10/msg00349.html>: when
trapping on underflow is enabled, extensions of subnormals from XFmode
to TFmode need to signal underflow because the result is tiny (but
exact, so the underflow flag is not raised unless trapping is
enabled).

To avoid any excess initialization or tests for other cases of
floating-point extensions, a new FP_INIT_TRAPPING_EXCEPTIONS is added
that does the initialization required for this particular case (more
than FP_INIT_EXCEPTIONS, less than FP_INIT_ROUNDMODE, in general), and
FP_NO_EXACT_UNDERFLOW is added to stub out FP_TRAPPING_EXCEPTIONS
tests for those cases of extensions where the test would be dead code,
to avoid any uninitialized variable warnings.

As the relevant case only applies in libgcc, not to any use of soft-fp
in glibc, there is no bug report in Bugzilla and no non-default
definitions of FP_INIT_TRAPPING_EXCEPTIONS are added by the patch.  A
testcase will be added to GCC as part of an update of soft-fp in
libgcc once this patch is in libc.

Tested for powerpc-nofpu that the disassembly of installed shared
libraries is unchanged by this patch.  Bootstrapped GCC with updated
soft-fp with no regressions on x86_64-unknown-linux-gnu and verified
that a test of the relevant case passes where it failed before.

	a subnormal result, set the underflow exception if trapping on
	underflow is enabled.

	* soft-fp/extendxftf2.c (__extendxftf2): Use

soft-fp: Refactor exception handling for comparisons.

This patch refactors how soft-fp comparisons handle setting exceptions
for NaN operands, so that exceptions are set through the FP_CMP macros
rather than directly in the C files calling them.

The _FP_CMP* and FP_CMP* macros gain an extra argument to specify when
exceptions should be set, 0 for no exception setting (I'm not sure
this is actually needed - at least it's not needed for IEEE operations
in glibc / libgcc, but might be relevant in some cases for kernel
use), 1 for exceptions only for signaling NaNs and 2 for exceptions
for all NaNs.  This argument is handled through _FP_CMP_CHECK_NAN,
newly called by the _FP_CMP* macros when a NaN is encountered.  Calls
to these macros are updated, which eliminates all the existing
checking and exception setting in soft-fp *.c files in glibc.

Tested for powerpc-nofpu.  (The __unord* functions have no code
changes; the __eq* / __ge* / __le* functions get slightly larger, but
I don't think that's significant.)

soft-fp: Fix _FP_TO_INT latent bug in overflow handling.

This patch fixes a latent bug in _FP_TO_INT regarding handling of
arguments with maximum exponent (infinities and NaNs).  If the maximum
exponent is below that calculated as an overflow threshold, such
values would incorrectly be treated as normal values for the purposes
of the conversion.  This could not occur for any of the conversions
actually occurring in glibc, libgcc or the Linux kernel (the maximum
exponent for float is, just, big enough to ensure overflow for
unsigned __int128), but would apply if soft-fp were used for IEEE
binary16.  Appropriate checks are inserted to ensure that the maximum
exponent is always treated as an overflowing exponent, and never as a
normal one.

Tested for powerpc-nofpu that the disassembly of installed shared
libraries is unchanged by this patch.

	* soft-fp/op-common.h (_FP_TO_INT): Ensure maximum exponent is
	treated as invalid conversion, not as normal exponent.
soft-fp: Add FP_DENORM_ZERO.

Continuing the addition of soft-fp features used in the Linux kernel,
this patch adds soft-fp support for FP_DENORM_ZERO (flushing input
subnormal operands to zero of the same sign).

There are some differences from the kernel version.  In the kernel,
the "inexact" exception is set when flushing to zero.  This does not
appear to match the documented semantics for either of the
architectures (alpha and sh) for which the kernel uses FP_DENORM_ZERO,
so this patch does not set "inexact" in this case.  More operations
now use raw or semi-raw unpacking for optimization than did in the
ten-year-old soft-fp version in the kernel, so checks of
FP_DENORM_ZERO are inserted in those operations.  They are also
inserted for comparisons (which already used raw unpacking in the old
version) as I believe that's the correct thing to do when input
subnormals are flushed to zero.  They are *not* inserted for _FP_NEG.
(If any processors do flush input subnormals to zero for negation, or
otherwise vary from the rules implemented when FP_DENORM_ZERO is set,
further macros for sfp-machine.h to control this may need to be
added.)

Although the addition for comparisons will cause FP_EX_DENORM to be
set in this case, it still won't be set for comparisons involving
subnormals when not flushed to zero.  It's quite possible that
accurate emulation of processors that have such an exception for
subnormal operands will require further changes relating to when
FP_EX_DENORM is set (in general, the support for things defined by
IEEE should be considered more reliable and mature than the support
for things outside the scope of IEEE floating point).

Although some processors also have a mode for abrupt underflow -
producing zeroes instead of output subnormals - there is no such mode
in the kernel's soft-fp, so no such mode is added to glibc's soft-fp
(although it could be if someone wanted to emulate such processor
support).

libraries is unchanged by this patch.

Remove stray *_internal aliases (bug 14132).

soft-fp: Support more precise "invalid" exceptions.

As previously discussed
<https://sourceware.org/ml/libc-alpha/2013-10/msg00345.html>, it would
be desirable to be able to use the same version of the soft-fp code in
the Linux kernel as well as in glibc and libgcc (instead of an old
version in the kernel that's missing ten years of bug fixes,
performance improvements and new features), and to that end it is
useful to add to glibc's copy features in the kernel's copy, even when
they are not directly useful in glibc.

To that end, this patch adds one of those features: support for more
precise "invalid" exceptions describing the particular kind of invalid
operation.  These are relevant for powerpc emulation, and are also as
described in IEEE 754-2008 as sub-exceptions.

The set of sub-exceptions here is the union of those supported on
powerpc and those from IEEE 754-2008 (the former adds a distinction
between 0/0 and Inf/Inf; the latter adds a distinction between Inf*0
from multiplication and the same from fma).  This includes
sub-exceptions for sqrt, conversions to integer and comparisons that
are not supported in the kernel; I see no obvious reason for these
being missing from the kernel support, given that they are supported
on powerpc so accurate powerpc emulation should generate them.

Tested for powerpc-nofpu that the disassembly of installed shared
libraries is unchanged by this patch.

soft-fp: Support rsigned == 2 in _FP_TO_INT.

Continuing the addition of soft-fp features in the Linux kernel
version, this patch adds _FP_TO_INT support for rsigned == 2 (reduce
overflowing results modulo 2^rsize to fit in the destination, used for
alpha emulation).

The kernel version is buggy; it can left shift by a negative amount
when right shifting is required in an overflow case (the kernel
version also has other bugs fixed long ago in glibc; at least,
spurious exceptions converting to the most negative integer).  This
version avoids that by handling overflow (other than to 0) for rsigned
== 2 along with the normal non-overflow case, which already properly
determines the direction in which to shift.

Tested for powerpc-nofpu.  Some functions get slightly bigger and some
get slightly smaller, no doubt as a result of the change to where in
the macro "inexact" is raised, but I don't think those changes are
significant.  Also tested for powerpc-nofpu with the relevant __fix*
functions changed to use rsigned == 2 (which is after all just as
valid as rsigned == 1 in IEEE terms), including verifying the results
and exceptions for various cases of conversions.

With these seven patches, the one remaining feature to add for the
soft-fp code to have all the features of the kernel version is
_FP_TO_INT_ROUND.

	* soft-fp/op-common.h (_FP_TO_INT): Handle rsigned == 2.
soft-fp: Use parentheses around macro arguments.

This patch cleans up the soft-fp code to use parentheses around macro
arguments (where possible; many macro arguments are identifiers used
with ## rather than arbitrary expressions, so cannot be put in
parentheses).  (I'm not aware of any bugs caused by the lack of
parentheses, but this is generally good practice.  The patch is not
exhaustive regarding internal macros where the arguments always come
directly from the mantissa of a floating-point number, although
probably those should be cleaned up in this regard as well.)

Tested for powerpc-nofpu that the installed shared libraries are
unchanged by this patch.

remove nested functions from elf/dl-load.c
Don't use INTVARDEF/INTUSE with __libc_enable_secure (bug 14132).

Continuing the removal of the obsolete INTDEF / INTVARDEF / INTUSE
mechanism, this patch replaces its use for __libc_enable_secure with
the use of rtld_hidden_data_def and rtld_hidden_proto.

Tested for x86_64 that installed stripped shared libraries are
unchanged by the patch.

	[BZ #14132]
	* elf/dl-sysdep.c (__libc_enable_secure): Use rtld_hidden_data_def
	instead of INTVARDEF.
	(_dl_sysdep_start): Do not use INTUSE with __libc_enable_secure.
	* sysdeps/mach/hurd/dl-sysdep.c (__libc_enable_secure): Use

Remove CANCEL-FCT-WAIVE and CANCEL-FILE-WAIVE.

As far as I can tell, CANCEL-FCT-WAIVE and CANCEL-FILE-WAIVE are old
notes from the addition of cancellation support to glibc and are not
currently used by any glibc testcases or otherwise in the build
process, and it does not seem useful to me to keep them around.  This
patch removes them.

Tested for x86_64.

	* CANCEL-FCT-WAIVE: Remove file.
	* CANCEL-FILE-WAIVE: Likewise.
Fix infinite loop in check_pf (BZ #12926)

The recvmsg could return 0 under some conditions and cause the
make_request function to be stuck in an infinite loop.

Thank you Jim King <jim.king@simplivity.com> for posting Paul's patch
on the list.
conformtest: clean up POSIX expections for sys/utsname.h, sys/wait.h.

Continuing the series of patches to clean up conformtest expectations
for "POSIX" (1995/6) based on review of the expectations against the
standard, this patch cleans up expectations for sys/utsname.h and
sys/wait.h.  Tested x86_64; a new XFAIL for sys/wait.h is added.
