846d9a4a3a Fix i386 / x86_64 nearbyint exception clearing (bug 15491). 
The implementations of nearbyint functions using x87 floating point
(i386 all versions, x86_64 long double only) use the fclex
instruction, which clears any exceptions that were raised before the
function was called.  These functions must not clear exceptions that
were raised before they were called.

This patch fixes these functions to save and restore the whole
floating-point environment (fnstenv / fldenv) as the way of avoiding
raising "inexact" (recall that there isn't an x87 instruction for
loading just the status word, so the whole environment has to be saved
and loaded instead - the code already saved and loaded the control
word, which is now obtained from the saved environment after this
patch, to disable traps on "inexact").  In the case of the long double
functions, any "invalid" exception from frndint (applied to a
signaling NaN) needs merging into the saved state; this issue doesn't
apply to the float and double functions because that exception would
have been raised when the argument is loaded, before the environment
is saved.

	[BZ #15491]
	* sysdeps/i386/fpu/s_nearbyint.S (__nearbyint): Save and restore
	floating-point environment instead of clearing all exceptions.

45ccb8346b Update NEWS to mention drive-by fix for bug 18699. 
Wilco fixed this tilegx bug in commit fe8c2b33ae ("Since we
now inline isinf, isnan and isfinite in math.h, replace uses
of __isinf_ns(l/f) with isinf, and remove the unused inlines
__isinf_ns(l/f), __isnan(f) and __finite(f).")

I verified that reverting math/s_cprojf.c back to using the
sysdeps/ieee754/flt-32/math_private.h version of __isinf_nsf()
instead of isinf() brings back the bug on tilegx.

c2c904ffd3 Cleanup sync_file_range implementation 
Since GLIBC requires a minimum 2.6.32 kernel, the patch cleanups
the mips code to assume __NR_sync_file_range and the powerpc one
to either assume __NR_sync_file_range2 or __NR_sync_file_range.

Checked on powerpc64le and build for mips (ABIO32, ABIN32, and ABI64).

	* sysdeps/unix/sysv/linux/powerpc/powerpc64/sync_file_range.c
	(__NR_sync_file_range2): Assume it is always defined.
	* sysdeps/unix/sysv/linux/mips/mips32/sync_file_range.c
	(__NR_sync_file_range): Assume it is always defined.

1ee1218e3f Move io/tst-fcntl temporary file creation to do_prepare. 
This patch makes the io/tst-fcntl test create its temporary file in
do_prepare not do_test, so that add_temp_name is called in the parent
on the correct file name, as requested in the thread starting at
<https://sourceware.org/ml/libc-alpha/2015-10/msg00552.html>.  I don't
see any reason in this test that opening the file in the parent should
be problematic.

This patch is explicitly not exhaustive for such issues; other tests
still call add_temp_file in the child.  The general issue is noted at
<https://sourceware.org/glibc/wiki/Development_Todo/Master#Use_test-skeleton.c>.

Tested for x86_64 (that this test still passes and no longer leaves a
file behind in /tmp).

	* io/tst-fcntl.c (fd): New static variable.
	(do_prepare): Open temporary file here....
	(do_test): ...not here.

1107424331 Make io/ftwtest-sh remove temporary files on early exit. 
The test io/ftwtest-sh creates a directory that at some points during
the test does not have execute permission.  To avoid leaving behind
such a directory that prevents the build directory from being removed
with a simple "rm -rf", it traps various signals to make the directory
executable and remove it before exit.  However, this doesn't cover the
case where one of the tests simply fails (which happens with cross
testing if testing on a remote system where the path to the build
directory involves a symlink, or if that remote system fell over
during testing - I think the latter is the case where the directory is
left behind with bad permissions).

This patch makes that test also trap signal 0 (exit) so that the
directory gets properly removed in such failure cases as well.

Tested in both configurations where the test passes and where it fails
to verify that the result of the test is unchanged but the directory
is no longer left behind where it was previously left behind.

	* io/ftwtest-sh: Also trap on exit to remove temporary files.

0a90a8f2b9 Fix ldbl-128 j0l spurious underflows (bug 19156). 
My recent addition of more tests for j0 showed up that the ldbl-128
implementation of j0l produces spurious underflow exceptions for
arguments close to 0 (when the result is very close to 1).  This patch
fixes this by just returning the argument in that case.

Tested for mips64 (where it fixes the recently-added tests that were
previously failing).

	[BZ #19156]
	* sysdeps/ieee754/ldbl-128/e_j0l.c (__ieee754_j0l): Return 1 for

Since asm ("ebp") can't be used to put the 6th argument in %ebp for

8e2f7c6811 Use -Wold-style-definition. 
This patch makes glibc build with -Wold-style-definition to avoid
old-style function definitions creeping back in by accident.

Tested for x86_64 and x86 (testsuite, and that installed shared
libraries are unchanged by the patch).  Also tested build for arm,
mips64 and powerpc32.  Hopefully there aren't any remaining
system-specific files with old-style definitions whose formatting
evaded my searches, but if there are, they will be easy to fix.

	* Makeconfig (+gccwarn-c): Add -Wold-style-definition.
	* Makefile ($(objpfx)c++-types-check.out): Filter out
	$(+gccwarn-c) instead of -Wstrict-prototypes.

80d9be8122 Convert miscellaneous function definitions to prototype style. 
This patch converts various miscellaneous functions definitions in
glibc, found with grep and not covered by my previous scripted
conversions, from old-style K&R to prototype-style.  These changes
were made manually.  This is not necessarily exhaustive as formatting
variants may have prevented my grep from finding some such
definitions.

Regarding the changes to files from GMP, they may originally have been
omitted when removing __STDC__ conditionals because of the files
coming from another package, but (a) GMP no longer has __STDC__
conditionals there anyway and (b) we don't try to keep these files
verbatim in sync with GMP (and there are licensing differences), so
making the change to them in glibc seems reasonable.

containing assertions).

9dd346ff43 Convert 113 more function definitions to prototype style (files with assertions). 
This mostly automatically-generated patch converts 113 function
definitions in glibc from old-style K&R to prototype-style.  Following
my other recent such patches, this one deals with the case of function
definitions in files that either contain assertions or where grep
suggested they might contain assertions - and thus where it isn't
possible to use a simple object code comparison as a sanity check on
the correctness of the patch, because line numbers are changed.

A few such automatically-generated changes needed to be supplemented
by manual changes for the result to compile.  openat64 had a prototype
declaration with "..." but an old-style definition in
sysdeps/unix/sysv/linux/dl-openat64.c, and "..." needed adding to the
generated prototype in the definition (I've filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68024> for diagnosing
such cases in GCC; the old state was undefined behavior not requiring
a diagnostic, but one seems a good idea).  In addition, as Florian has
noted regparm attribute mismatches between declaration and definition
are only diagnosed for prototype definitions, and five functions
needed internal_function added to their definitions (in the case of
__pthread_mutex_cond_lock, via the macro definition of
__pthread_mutex_lock) to compile on i386.

After this patch is in, remaining old-style definitions are probably
most readily fixed manually before we can turn on
-Wold-style-definition for all builds.

Tested for x86_64 and x86 (testsuite).

864198ed30 Remove gnu_unique_object configure test. 
There is a configure test for assembler support for the
gnu_unique_object symbol type.  This support was added in binutils
2.20, so is present in all versions supported for building glibc.

Thus, I think the configure test can be removed; this patch does so.
Now, there is a caveat that the gas NEWS entry refers to this as a
feature for GNU/Linux targets.  But the condition is use of
ELFOSABI_GNU or ELFOSABI_NONE.  ELFOSABI_GNU covers Hurd as well as
GNU/Linux (as was the case with the older ELFOSABI_LINUX name), and
ELFOSABI_NONE means this is effectively OS-independent.  Furthermore,
I think a correct binutils port for any glibc target ought to support
this feature for use with glibc; glibc supports this as an
OS-independent feature (the configure test is only about glibc
testcases).

Tested for x86_64 (testsuite, and that installed shared libraries are
unchanged by the patch).

6ab674ebff use -fstack-protector-strong when available 
With gcc-4.9, a new -fstack-protector-strong flag is available that is
between -fstack-protector (pretty weak) and -fstack-protector-all (pretty
strong) that provides good trade-offs between overhead but still providing
good coverage.  Update the places in glibc that use ssp to use this flag
when it's available.

This also kills off the indirection of hardcoding the flag name in the
Makefiles and adding it based on a have-ssp boolean.  Instead, the build
always expands the $(stack-protector) variable to the best ssp setting.
This makes the build logic a bit simpler and allows people to easily set
to a diff flag like:
	make stack-protector=-fstack-protector-all

6ec52bf634 PowerPC: Fix a race condition when eliding a lock 
The previous code used to evaluate the preprocessor token is_lock_free to
a variable before starting a transaction.  This behavior can cause an
error if another thread got the lock (without using a transaction)
between the evaluation of the token and the beginning of the transaction.

This bug can be triggered with the following order of events:
1. The lock accessed by is_lock_free is free.
2. Thread T1 evaluates is_lock_free and stores into register R1 that the
   lock is free.
3. Thread T2 acquires the same lock used in is_lock_free.
4. T1 begins the transaction, creating a memory barrier where is_lock_free
   is false, but R1 is true.
5. T1 reads R1 and doesn't abort the transaction.
6. T1 calls ELIDE_UNLOCK, which reads false from is_lock_free and decides
   to unlock a lock acquired by T2, leading to undefined behavior.

This patch delays the evaluation of is_lock_free to inside a transaction
by moving this part of the code to the macro ELIDE_LOCK.

2028f49dab pt_chown: Clear any signal mask inherited from the parent process. 
If grantpt() is called from a thread that is masking signals (for
instance, from a program using signalfd or using a dedicated
signal-handling thread), then that mask will get inherited to pt_chown.
This means that signals like SIGINT will not interrup pt_chown, so if it
hangs (e.g., because getgrnam("tty") hangs on a remote name service),
Ctrl-C will terminate the parent process but leave pt_chown around. Since
it's setuid, it's hard to kill any other way.

It is safe for pt_chown to unmask all signals, because grantpt() can be
(and usually is) called from an unprivileged process with all signals
unmasked.

bd2260a206 Convert 231 sysdeps function definitions to prototype style. 
This mostly automatically-generated patch converts 231 sysdeps
function definitions in glibc from old-style K&R to prototype-style.

For __aio_sigqueue and __gai_sigqueue I had to add internal_function

the functions compiling on x86 after conversion to prototype
definitions.  Otherwise, the patch is automatically generated with all
the same exclusions and caveats as in

that it's a patch for sysdeps files.

c7266a2d82 hu_HU: change time separator to colon [BZ #18918] 
The previous (11th) version of the Hungarian spelling rules (released
in 1984) said that the separator had to be a dot, e.g. 10.35 meaning
10 o'clock 35 minutes. glibc correctly implements this.

The brand new (12th) version, in effect since September 1, 2015 adopts
to the common use of colon (especially in the digital world) and
allows to use either separator, without even expressing a preference.

For computer systems, using colons is way more typical and probably
easier to recognize. Dot is typically used in printed materials.

It also avoids an almost ambiguous situation where a space makes a
difference, e.g. "10.15-ig" means "until 10 o'clock 15 minutes"
whereas "10. 15-ig" means "until 15th of October". So I believe using
the colon as the separator is not only more frequent in the computer
world, but is also easier and quicker to recognize for the brain that
it's about hour:minute rather than month and day. And luckily it's now
equally correct according to the official rules.

11th edition: http://helyesiras.mta.hu/helyesiras/default/akh11

12th edition: http://helyesiras.mta.hu/helyesiras/default/akh12

In both editions it's the very last (299th and 300th, respectively) rule.

Microsoft also uses and recommends a colon since at least May 2011:

  The time format is different in common language and in the language of
  IT. In common texts we usually do not abbreviate, so the full forms are
  used: “7 óra 10 perckor csörgött a telefon”. However, the short format,
  consisting of numerals only, can also be used. In this case a period
  must be used between the two numbers and there must not be a space
  between them: “találkozzunk 10.45-kor”.

  However, in software mostly the short format is used, and the numbers
  are separated by a colon. An obvious example is the clock in the bottom
  right corner of your screen, thus 18:31.

b0c3e04b71 Add more tests for ceil, floor, round, trunc. 
This patch adds more tests for ceil, floor, round and trunc, with a
particular focus on verifying they don't raise spurious "inexact"
exceptions for integer arguments (a C99 / C11 requirement, as opposed
to the general principle that they shouldn't raise "inexact" for any
arguments at all which is a TS 18661-1 requirement).

Tested for x86_64 and x86.

9d46370ca3 Convert 703 function definitions to prototype style. 
This automatically-generated patch converts 703 function definitions
in glibc from old-style K&R to prototype-style.

This conversion is deliberately simplistic, excluding any tricky cases
as even a patch covering only simple cases is still very large.
Currently excluded are: sysdeps files (to improve test coverage for
the initial patch); files containing assertions (to avoid line number
changes so that generated libraries can be compared); any cases where
the generated function declaration would involve lines over 79
characters and so need to be wrapped; any cases with array parameters
or other cases where parameter declarators don't end with the
parameter name; any other cases that my script didn't parse.

I didn't try to make the ChangeLog generation indicate when function
definitions are conditional; it just lists the functions changed
without regard to that.

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

15306e3888 Remove NPTL configure errors based on top-level configure tests. 
sysdeps/nptl/configure.ac has code to give errors if certain tests in
the top-level configure failed.  However, all those failure conditions
also produce errors in the top-level configure, so the errors in the
NPTL configure are completely redundant; this patch removes them.

(As suggested in
<https://sourceware.org/ml/libc-alpha/2015-10/msg00510.html>, I think
the top-level tests in question can be completely removed as
unnecessary given the version tests.  But even without that there is
clearly no point in duplicating code that gives an error if the test
fails.)

Tested for x86_64 (testsuite, and that installed shared libraries are
unchanged by the patch).

	* sysdeps/nptl/configure.ac: Do not give errors based on the
	results of top-level configure tests.

There is a configure test for -fexceptions.  This option was added in
GCC 2.8, so the test is obsolete - and indeed plenty of code is using

makes all uses of $(exceptions) use -fexceptions directly.

cf1455657e Do not leave files behind in /tmp from testing. 
I noticed that glibc testsuite runs left several files behind in /tmp
(or TMPDIR, if different).  The problem was testcases that generate a
template for mkstemp / mkstemp64, ending with XXXXXX, then pass that
template to add_temp_file before calling mkstemp / mkstemp64, meaning
that the template ending with XXXXXX is stored in the list of
temporary files to delete (add_temp_file uses strdup so that the
original string doesn't need to stay live), not the actual filename as
determined by mkstemp / mkstemp64.  This patch fixes those tests to
call add_temp_file later.

Tested for x86_64 (that the files are no longer left behind by a
testsuite run and the modified tests still pass).

fadd2ad9cc powerpc: Optimize lock elision for pthread_mutex_t 
With TLE enabled, the adapt count variable update incurs
an 8% overhead before entering the critical section of an
elided mutex.

Instead, if it is done right after leaving the critical
section, this serialization can be avoided.

This alters the existing behavior of __lll_trylock_elision
as it will only decrement the adapt_count if it successfully
acquires the lock.
