This patch consolidates the accept Linux syscall implementation on
sysdeps/unix/sysv/linux/accept.c. The changes are:
1. Remove accept from auto-generation syscalls.list on the architecture
that uses __NR_accept.
2. Define __NR_accept as default (__ASSUME_ACCEPT_SYSCALL) and undef for
architectures that do not support it.
3. Remove __ASSUME_ACCEPT4_FOR_ACCEPT_SYSCALL and decide to use
__NR_accept4 for accept generation based on __ASSUME_ACCEPT4_SYSCALL.
Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,
aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.
* sysdeps/unix/sysv/linux/accept.c (__libc_accept): Replace
__ASSUME_ACCEPT4_FOR_ACCEPT_SYSCALL by __ASSUME_ACCEPT4_SYSCALL.

This patch adds tests for POSIX and Linux specific syscalls
that implemented with syscall templates machinery. The reason
of tests is to receive the expected error code and test if
it's handled properly by glibc.

The LD_HWCAP_MASK environment variable may alter the selection of
function variants for some architectures. For AT_SECURE process it
means that if an outdated routine has a bug that would otherwise not
affect newer platforms by default, LD_HWCAP_MASK will allow that bug
to be exploited.
To be on the safe side, ignore and disable LD_HWCAP_MASK for setuid
binaries.

In 1e5834c38a ("Refactor Linux ipc_priv header") a different
approach to passing __IPC_64 as zero was created. Hppa kernel ABI
requires to oass __IPC_64 as zero since it does not set
CONFIG_ARCH_WANT_IPC_PARSE_VERSION in the kernel.
Checked on hppa-linux-gnu with some adjustments to avoid BZ#21016
(basically by removing hppa compat implementations and adjusting
required headers).
* sysdeps/unix/sysv/linux/hppa/ipc_priv.h: New file.
This patch activates C11 atomic builtins by defining
USE_ATOMIC_COMPILER_BUILTINS to 1.
Note:
E.g. in nptl/pthread_key_delete.c if compiled with GCCs 6 and before,
an extra stack-frame is generated and the old value is stored on stack
before cs instruction but it never loads this value from stack.
An unreleased GCC 7 omit those stack operations.
E.g. in nptl/pthread_once.c the condition code of cs instruction is
evaluated by a sequence of ipm, sra, compare and jump instructions instead
of one conditional jump instruction. This also occurs with an unreleased
GCC 7.
These shortcomings does not really hurt. Nevertheless, the gcc guys are
investigating those ones and plan to fix them before GCC 7 release.
The atomic_fetch_abc_def C11 builtins are now using load-and-abc instructions
on z196 zarch and higher cpus instead of a loop with compare-and-swap
instruction.
Some of the non-C11 atomic macros from include/atomic.h are now implemented
with help of the C11 atomic builtins. The other non-C11 atomic macros
are using the macros defined here.
ChangeLog:
* sysdeps/s390/atomic-machine.h

posix/wordexp-test.c used libc-internal.h for PTR_ALIGN_DOWN; similar
to what was done with libc-diag.h, I have split the definitions of
cast_to_integer, ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and PTR_ALIGN_DOWN
to a new header, libc-pointer-arith.h.
It then occurred to me that the remaining declarations in libc-internal.h
are mostly to do with early initialization, and probably most of the
files including it, even in the core code, don't need it anymore. Indeed,
only 19 files actually need what remains of libc-internal.h. 23 others
need libc-diag.h instead, and 12 need libc-pointer-arith.h instead.
No file needs more than one of them, and 16 don't need any of them!
So, with this patch, libc-internal.h stops including libc-diag.h as
well as losing the pointer arithmetic macros, and all including files
are adjusted.
* include/libc-pointer-arith.h: New file. Define
cast_to_integer, ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and
PTR_ALIGN_DOWN here.

These are a grab bag of changes where the testsuite was using internal
symbols of some variety, but this was straightforward to fix, and the
fixed code should work with or without the change to compile the
testsuite under _ISOMAC.
Four of these are just more #include adjustments, but I want to highlight
sysdeps/powerpc/fpu/tst-setcontext-fpscr.c, which appears to have been
written before the advent of sys/auxv.h. I think a big chunk of this file
could be replaced by a simple call to getauxval, but I'll let someone who
actually has a powerpc machine to test on do that.
dlfcn/tst-dladdr.c was including ldsodefs.h just so it could use
DL_LOOKUP_ADDRESS to print an additional diagnostic; as requested by Carlos,
I have removed this.
math/test-misc.c was using #ifndef NO_LONG_DOUBLE, which is an internal
configuration macro, to decide whether to do certain tests involving
'long double'. I changed the test to #if LDBL_MANT_DIG > DBL_MANT_DIG
instead, which uses only public float.h macros and is equivalent on
all supported platforms. (Note that NO_LONG_DOUBLE doesn't mean 'the
compiler doesn't support long double', it means 'long double is the
same as double'.)
tst-writev.c has a configuration macro 'ARTIFICIAL_LIMIT' that the
Makefiles are expected to define, and sysdeps/unix/sysv/linux/Makefile
was using the internal __getpagesize in the definition; changed to
sysconf(_SC_PAGESIZE) which is the POSIX equivalent.
ia64-linux doesn't supply 'clone', only '__clone2', which is not
defined in the public headers(!) All the other clone tests have local
extern declarations of __clone2, but tst-clone.c doesn't; it was
getting away with this because include/sched.h does declare __clone2.
* nss/tst-cancel-getpwuid_r.c: Include nss.h.
* string/strcasestr.c: No need to include config.h.
* sysdeps/powerpc/fpu/tst-setcontext-fpscr.c: Include
sys/auxv.h. Don't include sysdep.h.
* sysdeps/powerpc/tst-set_ppr.c: Don't include dl-procinfo.h.
* dlfcn/tst-dladdr.c: Don't include ldsodefs.h. Don't use
DL_LOOKUP_ADDRESS.
* math/test-misc.c: Instead of testing NO_LONG_DOUBLE, test whether
LDBL_MANT_DIG is greater than DBL_MANT_DIG.
* sysdeps/unix/sysv/linux/Makefile (CFLAGS-tst-writev.c): Use
sysconf (_SC_PAGESIZE) instead of __getpagesize in definition
of ARTIFICIAL_LIMIT.
* sysdeps/unix/sysv/linux/tst-clone.c [__ia64__]: Add extern
declaration of __clone2.
This commit fixes various aspects in the UDP client timeout handling.
Timeouts are now applied in a more consistent fashion. Discarded UDP
packets no longer prevent the timeout from happening at all.
The change in commit 718946816c
has no effect because of two bugs which cancel each other out:
The svc_is_mapped condition is inverted, and svc_is_mapped
always returns false because the check is performed after
the service has already been unregistered. As a result,
pmap_unset is called unconditionally, as before.
After commit bc779a1a5b
(CVE-2016-4429: sunrpc: Do not use alloca in clntudp_call
[BZ #20112]), ancillary data is stored on the heap,
but it is accessed after it has been freed.
The test case must be run under a heap debugger such as valgrind
to observe the invalid access. A malloc implementation which
immediately calls munmap on free would catch this bug as well.
A few 'long double'-related tests include math_private.h just for
their variety of math_ldbl.h, which contains macros for assembling and
disassembling the binary representation of 'long double'. math_ldbl.h
insists on being included from math_private.h, but if we relax this
restriction (and fix some portability sloppiness) we can use it
directly and not have to expose all of math_private.h to the testsuite.
* sysdeps/generic/math_private.h: Use __BIG_ENDIAN and
__LITTLE_ENDIAN, not BIG_ENDIAN and LITTLE_ENDIAN.

Include math_ldbl.h, not math_private.h.
Quite a few tests include libc-internal.h just for the DIAG_* macros.
Split those macros to their own file, which can be included safely in
_ISOMAC mode. I also moved ignore_value, since it seems logically
related, even though I didn't notice any tests needing it.
Also add -Wnonnull suppressions to two tests that _should_ have them,
but the error is masked when compiling against internal headers.
* include/libc-diag.h: New file. Define ignore_value,
DIAG_PUSH_NEEDS_COMMENT, DIAG_POP_NEEDS_COMMENT,
DIAG_IGNORE_NEEDS_COMMENT, and DIAG_IGNORE_Os_NEEDS_COMMENT here.
* include/libc-internal.h: Definitions of above macros moved from

gets has the dubious honor of being the only C89 library feature that
has been completely removed from the current C and C++ standards.
glibc follows suit by not declaring it in _GNU_SOURCE mode either,
but it remains present in older compatibility modes. Internally,
two test cases need to see stdio.h make the declaration, but all our
internal code is of course compiled under _GNU_SOURCE. This is currently
kludged by duplicating the gets declaration, fortify wrapper and all,
in include/stdio.h. Also, the conditional in the public headers for
deciding when to declare gets is complicated and repeated in two places.
This patch adds a new macro to features.h that encapsulates the
complicated rule for when to declare gets. stdio.h and bits/stdio2.h
then simply test __GLIBC_USE (DEPRECATED_GETS), and instead of having
a duplicate gets declaration in include/stdio.h, debug/tst-chk1.c and
stdio-common/tst-gets.c can force gets to be declared.
* include/features.h (__GLIBC_USE_DEPRECATED_GETS): New macro.
* libio/stdio.h, libio/bits/stdio2.h: Condition gets on
__GLIBC_USE (DEPRECATED_GETS). Update comments to indicate
gets was removed from C++ in C++14.
* include/stdio.h: Remove redundant declaration of gets.
* debug/tst-chk1.c, stdio-common/tst-gets.c: Force gets to
be declared, since we are testing it.
* stdio-common/Makefile (tst-gets.c): Compile with
-Wno-deprecated-declarations.
* debug/Makefile (tst-chk1.c, tst-chk2.c, tst-chk3.c, tst-chk4.cc)
(tst-chk5.cc, tst-chk6.cc, tst-lfschk1.c, tst-lfschk2.c)
(tst-lfschk3.c, tst-lfschk4.cc, tst-lfschk5.cc, tst-lfschk6.cc):
Compile with -Wno-deprecated-declarations.
Compiling resolv/tst-resolv-qtypes.c with GCC 7 results in:
tst-resolv-qtypes.c:53:14: error: duplicate ‘const’ declaration specifier [-Werror=duplicate-decl-specifier]
static const const char *domain = "www.example.com";
This patch removes the duplicate const and makes domain a const pointer
to const char literal.
ChangeLog:
* resolv/tst-resolv-qtypes.c (domain):
Change type to const pointer to const char.
At present, libm tests for each function get built into a single
executable (for each floating point type, for each of normal / inline
/ finite-math-only functions, plus vector variants) and run together,
resulting in a single PASS or FAIL (for each of those nine variants
plus vector variants). Building this executable involves reading
over 50 MB of libm-test-*.c sources.
This patch arranges for tests of each function to be run separately
from the makefiles instead. There are 121 functions being tested for
each (type, variant pair) (actually 126, but run as 121 from the
Makefile because each of the pairs (exp10, pow10), (isfinite, finite),
(lgamma, gamma), (remainder, drem), (scalbn, ldexp), shares a table of
test results and so is run together), so 1089 separate tests run from
the Makefile, plus 48 vector tests on x86_64 (six functions for eight
vector variants). Each test only involves a libm-test-<func>.c file
of no more than about 4 MB, rather than all such files taking about 50
MB. With tests run separately, test summaries will indicate which
functions actually have problems (of course, those problems may just
be out-of-date libm-test-ulps files if the file hasn't been updated
for the architecture in question recently).
All the .c files for the 1089+48 tests are generated automatically
from the Makefiles. Various checked-in boilerplate .c files are
removed as no longer needed. CFLAGS definitions for the different
kinds of tests are generated using makefile iterators to apply
target-specific variable settings. libm-have-vector-test.h is no
longer needed; the list of functions to test for each vector type is
now in the sysdeps Makefile.
This should reduce the amount of boilerplate needed for float128
testing support; test-float128.h will still be needed, but not various
.c files or Makefile CFLAGS definitions. The logic for creating
dependencies on libm-test-support-*.o files should also render
<https://sourceware.org/ml/libc-alpha/2017-02/msg00279.html>
unnecessary.
Tested for x86_64 and x86.

In Linux 4.10, timerfd constants moved to a new uapi header, which
showed up that glibc's sys/timerfd.h is missing the old flag
TFD_TIMER_CANCEL_ON_SET. This patch adds that flag to glibc's header.
Tested for x86_64.
* sysdeps/unix/sysv/linux/sys/timerfd.h (TFD_TIMER_CANCEL_ON_SET):
New enum constant and macro.
Linux 4.10 adds a new IP_RECVFRAGSIZE macro to
include/uapi/linux/in.h. This patch adds it to glibc's
sysdeps/unix/sysv/linux/bits/in.h.
Tested for x86_64.

Change the powerpc tests to use <support/test-driver.c>.
Also replace some of pthread calls to its xpthread equivalent.
Tested on ppc64le.
* sysdeps/powerpc/test-get_hwcap.c: Use <support/test-driver.c>
instead of test-skeleton.c.
(do_test): Replaced pthread_create and pthread_join with
xpthread_create and xpthread_join. Use TEST_VERIFY_EXIT macro.
Removed unneeded status variable.

generator scripts contributed by Mike FABIAN (Red Hat).
This patch removes some libm-test-support.h macros for exceptions that
are no longer used. EXCEPTIONS_OK has been unused for some time. The
macros for underflow exceptions with some types only were used when
the results for complex inverse trig and hyperbolic functions were
manually maintained, but are no longer needed now the auto-libm-test
machinery is used to determine the correct result and exceptions for
every floating-point format and rounding mode.
Tested for x86_64.

Commit 6b1df8b27f fixed the -OS build issue on i386 (BZ#20729) by
expliciting disabling frame pointer (-fomit-frame-pointer) on the
faulty objects. Although it does fix the issue, it is a subpar
workaround that adds complexity in build process (a rule for each
object to add the required compiler option and pontentially more
rules for objects that call {INLINE,INTERNAL}_SYSCALL) and does not
allow the implementations to get all the possible debug/calltrack
information possible (used mainly in debuggers and performance
measurement tools).
This patch fixes it by adding an explicit configure check to see
if -fno-omit-frame-pointer is set and to act accordingly (set or
not OPTIMIZE_FOR_GCC_5). The make rules is simplified and only
one is required: to add libc-do-syscall on loader due mmap
(which will be empty anyway for default build with
-fomit-frame-pointer).
Checked on i386-linux-gnu with GCC 6.2.1 with CFLAGS sets as
'-Os', '-O2 -fno-omit-frame-pointer', and '-O2 -fomit-frame-pointer'.
For '-Os' the testsuite issues described by BZ#19463 and BZ#15105
still applied.
It fixes BZ #21029, although it is marked as duplicated of #20729
(I reopened to track this cleanup).

This patch moves tests of catan and catanh with finite inputs (other

the auto-libm-test machinery. Each of auto-libm-test-out-catan and
auto-libm-test-out-catanh takes about three seconds to generate on my

auto-libm-test-* until the output files were split up by function).

Tested for x86_64 and x86 and ulps updated accordingly.
* math/auto-libm-test-in: Add tests of cacos and cacosh.
* math/auto-libm-test-out-cacos: New generated file.
* math/auto-libm-test-out-cacosh: Likewise.
* math/libm-test-cacos.inc (cacos_test_data): Use AUTO_TESTS_c_c.
Move tests with finite inputs to auto-libm-test-in.
* math/libm-test-cacosh.inc (cacosh_test_data): Likewise.
* math/Makefile (libm-test-funcs-auto): Add cacos and cacosh.
(libm-test-funcs-noauto): Remove cacos and cacosh.
* sysdeps/i386/fpu/libm-test-ulps: Update.
* sysdeps/i386/i686/fpu/multiarch/libm-test-ulps: Likewise.
* sysdeps/x86_64/fpu/libm-test-ulps: Likewise.

The 'bot-cycle' action for build-many-glibcs is a convenient way to
not have to remember all the steps in keeping a many-glibcs tree up
to date ... or it would be, if the script could send mail _optionally_.
Make it so by skipping the mail step if mail isn't configured.
* scripts/build-many-glibcs.py (bot_build_mail): If the
bot_config does not contain all of the necessary email-
related settings, just print a warning and continue.
