af1e6be4ba powerpc: Fix llround spurious inexact on 32-bit POWER4 [BZ #22697]
This issue is similar to BZ #19235, where spurious exceptions are
created from adding 0.5 then converting to an integer.
The solution is based on Joseph's fix for BZ #19235.

	[BZ #22697]
	* sysdeps/powerpc/powerpc32/power4/fpu/s_llround.S (__llround):
	Do not add 0.5 to integer or out-of-range arguments.

3d1d79283e aarch64: fix static pie enabled libc when main is in a shared library
In the static pie enabled libc, crt1.o uses the same position independent
code as rcrt1.o and crt1.o is used instead of Scrt1.o when -no-pie
executables are linked.  When main is not defined in the executable, but
in a shared library crt1.o is currently broken, it assumes main is local.
(glibc has a test for this but i missed it in my previous testing.)

To make both rcrt1.o and crt1.o happy with the same code, a wrapper is
introduced around main: with this crt1.o works with extern main symbol
while rcrt1.o does not depend on GOT relocations. (The change only
affects static pie enabled libc. Further simplification of start.S is
possible in the future by using the same approach for Scrt1.o too.)

	* aarch64/start.S (_start): Use __wrap_main.
	(__wrap_main): New local symbol.

52a713fdd0 linux: make getcwd(3) fail if it cannot obtain an absolute path [BZ #22679]
Currently getcwd(3) can succeed without returning an absolute path
because the underlying getcwd syscall, starting with linux commit
v2.6.36-rc1~96^2~2, may succeed without returning an absolute path.

This is a conformance issue because "The getcwd() function shall
place an absolute pathname of the current working directory
in the array pointed to by buf, and return buf".

This is also a security issue because a non-absolute path returned
by getcwd(3) causes a buffer underflow in realpath(3).

Fix this by checking the path returned by getcwd syscall and falling
back to generic_getcwd if the path is not absolute, effectively making
getcwd(3) fail with ENOENT.  The error code is chosen for consistency
with the case when the current directory is unlinked.

f172187b2d hu_HU locale: Avoid double space (bug 22657).
The current date format prefixes one-digit days with a space, resulting
in ugly two spaces:

$ LC_ALL=hu_HU.UTF-8 date
2018. jan.  1., hétfő, 21:25:35 CET
          ^^

The official orthography rules doesn't contain an explicit rule about
this (which already gives no sane reason for double space), and an
implicit example of "1848. március 9." under bullet point 296 at
http://helyesiras.mta.hu/helyesiras/default/akh12 contains a single
space only. It's sure not convincing on an HTML page, but I confirm
that the official book edition (e.g.

c8924f1ff2 Fix s390 linknamespace fallout of bug 22702 patch.
My fix for bug 22702 introduced linknamespace test failures on
s390x-linux-gnu and s390-linux-gnu because it made remainder call
__feholdexcept, and the s390 __feholdexcept calls fegetenv, and
remainder is in Unix98 and XPG4.2 but fegetenv isn't.  This patch
makes __feholdexcept call __fegetenv instead to avoid that namespace
issue.

where it resolves the test failures.

da09e6fa2f Make default libc_feholdsetround_noex_ctx use __feholdexcept (bug 22702).
For soft-float powerpc, the math/test-nearbyint-except-2 test fails
because nearbyintl traps when traps on "inexact" are enabled on entry
(and an "inexact" exception is generated internally, though cleared
for the final return).

The problem is the default implementation of
libc_feholdsetround_noex_ctx, which does not disable exception traps.
There is some ambiguity about whether the *noex* interfaces are
required to do so or only permitted to do so.  But given that we
support fe* interfaces to enable and disable traps (on architectures
with that functionality), functions that must not raise an exception
(must not leave the flag set on exit if not set on entry) should also
not trap on it when traps on that exception are enabled.  So it is
appropriate to define these interfaces to have the feholdexcept effect
of disabling exception traps; this patch updates the default
implementation and comments accordingly.

At least some architecture versions already disable traps; there are
few uses of the *noex* interfaces at all, and while it's possible
there are bugs on any architecture versions failing to disable traps
that appear in the exp2 and remainder implementations, there are
currently no tests, other than this one for nearbyintl (where only the
ldbl-128ibm implementation uses SET_RESTORE_ROUND_NOEX), that would
fail as a result of such a bug.  (Hard-float powerpc does disable
traps here, hence the nearbyintl failure not appearing there.)

Tested for powerpc (soft-float).  This brings that configuration to
clean math/ test results, provided you build with GCC 8 to get the fix
for GCC bug 64811.

1272748886 Fix ldbl-128ibm lrintl, lroundl missing "invalid" exceptions (bug 22690).
The ldbl-128ibm implementations of lrintl and lroundl are missing
"invalid" exceptions for certain overflow cases when compiled with GCC
8.  The cause of this is after-the-fact integer overflow checks that
fail when the compiler optimizes on the basis of integer overflow
being undefined; GCC 8 must be able to detect new cases of
undefinedness here.

(Tested that these failures occur before the patch for powerpc
soft-float, but the issue applies in principle for hard-float as well,
whether or not the particular optimizations in fact occur there at
present.)

This patch fixes the bug by ensuring the additions / subtractions in
question cast arguments to unsigned long int, or use 1UL as a constant
argument, so that the arithmetic occurs in an unsigned type with the
result then converted back to a signed type.

e134ca1753 Fix powerpc-nofpu complex long double functions spurious "invalid" exception (bug 22687).
For soft-float powerpc, various _Complex long double functions
generate spurious "invalid" exceptions, even with a compiler with GCC
bug 64811 fixed.

The problem is GCC's built-in fabsl expansion.  Various files are
already built with -fno-builtin-fabsl because in this case (IBM long
double, for soft-float or e500v1) a fallback fabsl expansion based on
comparisons is used, which can produce the wrong sign of a zero
result.  Those comparisons can also produce spurious exceptions for
NaN arguments.  Furthermore, __builtin_fpclassify implemently uses
__builtin_fabsl, and is unaffected by -fno-builtin-fabsl, and the
fpclassify macro uses __builtin_fpclassify in the absence of
-fsignaling-nans.  Thus, this patch arranges for the problem files
using fpclassify to be built with -fsignaling-nans in this case, to
avoid spurious exceptions from fpclassify.

  TEST_COMPARE (ret,

                + strlen (expected_name));

This resulted in a failed static assertion, "integer conversions
may alter sign of operands".  A user of the TEST_COMPARE would have
to add a cast to fix this.

This patch reverts to the original proposed solution of a run-time
check, making TEST_COMPARE usable for comparisons of numbers with
types with different signedness in more contexts.

0050553251 Allow make-link-multidir to make subdirectories
The RISC-V Linux ABI doesn't define any libraries that go directly in
lib, instead they go into lib32/ilp32 or lib64/lp64.  This casuse
make-link-multidir to fail when attempting to make library directories
when building a static libc on multilib RISC-V systems.

This patch uses scripts/mkinstalldirs to make the base directory of the

19be56d8ce Add test for getrlimit/setrlimit/prlimit with infinity value
Add a test to check that the getrlimit, setrlimit and prlimit functions
and their 64-bit equivalent behave correctly with RLIM_INFINITY and
RLIM64_INFINITY. For that it assumes that the prlimit64 function calls
the syscall directly without translating the value and that the kernel
uses the -1 value to represent infinity.

It first finds a resource with the hard limit set to infinity so the
soft limit can be manipulated easily and check for the consistency
between the value set or get by the prlimit64 and the other functions.

It is Linux specific add it uses the prlimit and prlimit64 functions.

	* sysdeps/unix/sysv/linux/tst-rlimit-infinity.c: New file.
	* sysdeps/unix/sysv/linux/Makefile (tests): Add tst-rlimit-infinity.

24731685c8 prlimit: Translate old_rlimit from RLIM64_INFINITY to RLIM_INFINITY [BZ #22678]
prlimit called without a new value fails on 32-bit machines if any of
the soft or hard limits are infinity. This is because prlimit does not
translate old_rlimit from RLIM64_INFINITY to RLIM_INFINITY, but checks
that the value returned by the prlimit64 syscall fits into a 32-bit
value, like it is done for example in getrlimit. Note that on the
other hand new_rlimit is correctly translated from RLIM_INFINITY to
RLIM64_INFINITY before calling the syscall.

This patch fixes that.

0d0bc784ca Alpha: Add wrappers to get/setrlimit64 to fix RLIM64_INFINITY constant [BZ #22648]
RLIM64_INFINITY was supposed to be a glibc convention rather than
anything seen by the kernel, but it ended being passed to the kernel
through the prlimit64 syscall.

* On the kernel side, the value is defined for the prlimit64 syscall for
  all architectures in include/uapi/linux/resource.h:

  #define RLIM64_INFINITY           (~0ULL)

* On the kernel side, the value is defined for getrlimit and setrlimit
  in arch/alpha/include/uapi/asm/resource.h

  #define RLIM_INFINITY            0x7ffffffffffffffful

* On the GNU libc side, the value is defined in
  sysdeps/unix/sysv/linux/alpha/bits/resource.h:

  # define RLIM64_INFINITY 0x7fffffffffffffffLL

This was not an issue until the getrlimit and setrlimit glibc functions
have been changed in commit 045c13d185 ("Consolidate Linux setrlimit and
getrlimit implementation") to use the prlimit64 syscall instead of the
getrlimit and setrlimit ones.

This patch fixes that by adding a wrapper to fix the value passed to or
received from the kernel, before or after calling the prlimit64 syscall.

Changelog:
	[BZ #22648]
	* sysdeps/unix/sysv/linux/alpha/getrlimit64.c: New file.
	* sysdeps/unix/sysv/linux/alpha/setrlimit64.c: Ditto.
