SUBJECT: The GNU C Library version 2.26 is now available
The GNU C Library
=================
The GNU C Library version 2.26 is now available.
The GNU C Library is used as *the* C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2008. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.26 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
NEWS for version 2.26
=====================
Major new features:
* A per-thread cache has been added to malloc. Access to the cache requires
no locks and therefore significantly accelerates the fast path to allocate
and free small amounts of memory. Refilling an empty cache requires
locking
the underlying arena. Performance measurements show significant gains in a
wide variety of user workloads. Workloads were captured using a special
instrumented malloc and analyzed with a malloc simulator. Contributed by
DJ Delorie with the help of Florian Weimer, and Carlos O'Donell.
* Unicode 10.0.0 Support: Character encoding, character type info, and
transliteration tables are all updated to Unicode 10.0.0, using
generator scripts contributed by Mike FABIAN (Red Hat).
These updates cause user visible changes, especially the changes in
wcwidth for many emoji characters cause problems when emoji sequences
are rendered with pango, see for example:
https://bugzilla.gnome.org/show_bug.cgi?id=780669#c5
* Collation of Hungarian has been overhauled and is now consistent with "The
Rules of Hungarian Orthography, 12th edition" (Bug 18934). Contributed by
Egmont Koblinger.
* Improvements to the DNS stub resolver, contributed by Florian Weimer:
- The GNU C Library will now detect when /etc/resolv.conf has been
modified and reload the changed configuration. The new resolver option
âno-reloadâ (RES_NORELOAD) disables this behavior.
- The GNU C Library now supports an arbitrary number of search domains
(configured using the âsearchâ directive in /etc/resolv.conf);
previously, there was a hard limit of six domains. For backward
compatibility, applications that directly modify the â_resâ global
object are still limited to six search domains.
- When the ârotateâ (RES_ROTATE) resolver option is active, the GNU C
Library will now randomly pick a name server from the configuration as a
starting point. (Previously, the second name server was always used.)
* The tunables feature is now enabled by default. This allows users to
tweak
behavior of the GNU C Library using the GLIBC_TUNABLES environment
variable.
* New function reallocarray, which resizes an allocated block (like realloc)
to the product of two sizes, with a guaranteed clean failure upon integer
overflow in the multiplication. Originally from OpenBSD, contributed by
Dennis Wölfing and Rüdiger Sonderfeld.
* New wrappers for the Linux-specific system calls preadv2 and pwritev2.
These are extended versions of preadv and pwritev, respectively, taking an
additional flags argument. The set of supported flags depends on the
running kernel; full support currently requires kernel 4.7 or later.
* posix_spawnattr_setflags now supports the flag POSIX_SPAWN_SETSID, to
create a new session ID for the spawned process. This feature is
scheduled to be added to the next major revision of POSIX; for the time
being, it is available under _GNU_SOURCE.
* errno.h is now safe to use from C-preprocessed assembly language on all
supported operating systems. In this context, it will only define the
Exxxx constants, as preprocessor macros expanding to integer literals.
* On ia64, powerpc64le, x86-32, and x86-64, the math library now implements
128-bit floating point as defined by ISO/IEC/IEEE 60559:2011 (IEEE
754-2008) and ISO/IEC TS 18661-3:2015. Contributed by Paul E. Murphy,
Gabriel F. T. Gomes, Tulio Magno Quites Machado Filho, and Joseph Myers.
To compile programs that use this feature, the compiler must support
128-bit floating point with the type name _Float128 (as defined by TS
18661-3) or __float128 (the nonstandard name used by GCC for C++, and for
C prior to version 7). _GNU_SOURCE or __STDC_WANT_IEC_60559_TYPES_EXT__
must be defined to make the new interfaces visible.
The new functions and macros correspond to those present for other
floating-point types (except for a few obsolescent interfaces not
supported for the new type), with F128 or f128 suffixes; for example,
strtof128, HUGE_VAL_F128 and cosf128. Following TS 18661-3, there are no
printf or scanf formats for the new type; the strfromf128 and strtof128
interfaces should be used instead.
Deprecated and removed features, and other changes affecting compatibility:
* The synchronization that pthread_spin_unlock performs has been changed to
now be equivalent to a C11 atomic store with release memory order to the
spin lock's memory location. Previously, several (but not all)
architectures used stronger synchronization (e.g., containing what is
often called a full barrier). This change can improve performance, but
may affect odd fringe uses of spin locks that depend on the previous
behavior (e.g., using spin locks as atomic variables to try to implement
Dekker's mutual exclusion algorithm).
* The port to Native Client running on ARMv7-A (--host=arm-nacl) has been
removed.
* Sun RPC is deprecated. The rpcgen program, librpcsvc, and Sun RPC headers
will only be built and installed when the GNU C Library is configured with
--enable-obsolete-rpc. This allows alternative RPC implementations, such
as TIRPC or rpcsvc-proto, to be used.
* The NIS(+) name service modules, libnss_nis, libnss_nisplus, and
libnss_compat, are deprecated, and will not be built or installed by
default.
The NIS(+) support library, libnsl, is also deprecated. By default, a
compatibility shared library will be built and installed, but not headers
or development libraries. Only a few NIS-related programs require this
library. (In particular, the GNU C Library has never required programs
that use 'gethostbyname' to be linked with libnsl.)
Replacement implementations based on TIRPC, which additionally support
IPv6, are available from <https://github.com/thkukuk/>. The configure
option --enable-obsolete-nsl will cause libnsl's headers, and the NIS(+)
name service modules, to be built and installed.
* The DNS stub resolver no longer performs EDNS fallback. If EDNS or DNSSEC
support is enabled, the configured recursive resolver must support EDNS.
(Responding to EDNS-enabled queries with responses which are not
EDNS-enabled is fine, but FORMERR responses are not.)
* res_mkquery and res_nmkquery no longer support the IQUERY opcode. DNS
servers have not supported this opcode for a long time.
* The _res_opcodes variable has been removed from libresolv. It had been
exported by accident.
* <string.h> no longer includes inline versions of any string functions,
as this kind of optimization is better done by the compiler. The macros
__USE_STRING_INLINES and __NO_STRING_INLINES no longer have any effect.
* The nonstandard header <xlocale.h> has been removed. Most programs should
use <locale.h> instead. If you have a specific need for the definition of
locale_t with no other declarations, please contact
address@hidden and explain.
* The obsolete header <sys/ultrasound.h> has been removed.
* The obsolete signal constant SIGUNUSED is no longer defined by <signal.h>.
* The obsolete function cfree has been removed. Applications should use
free instead.
* The stack_t type no longer has the name struct sigaltstack. This changes
the C++ name mangling for interfaces involving this type.
* The ucontext_t type no longer has the name struct ucontext. This changes
the C++ name mangling for interfaces involving this type.
* On M68k GNU/Linux and MIPS GNU/Linux, the fpregset_t type no longer has
the name struct fpregset. On Nios II GNU/Linux, the mcontext_t type no
longer has the name struct mcontext. On SPARC GNU/Linux, the struct
mc_fq, struct rwindow, struct fpq and struct fq types are no longer
defined in sys/ucontext.h, the mc_fpu_t type no longer has the name struct
mc_fpu, the gwindows_t type no longer has the name struct gwindows and the
fpregset_t type no longer has the name struct fpu. This changes the C++
name mangling for interfaces involving those types.
* On S/390 GNU/Linux, the constants defined by <sys/ptrace.h> have been
synced with the kernel:
- PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS
are not supported on this architecture and have been removed.
- PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA,
PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE,
PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND have been added.
Programs that assume the GET/SETREGS ptrace requests are universally
available will now fail to build, instead of malfunctioning at runtime.
Changes to build and runtime requirements:
* Linux kernel 3.2 or later is required at runtime, on all architectures
supported by that kernel. (This is a change from version 2.25 only for
x86-32 and x86-64.)
* GNU Binutils 2.25 or later is now required to build the GNU C Library.
* On most architectures, GCC 4.9 or later is required to build the GNU C
Library. On powerpc64le, GCC 6.2 or later is required.
Older GCC versions and non-GNU compilers are still supported when
compiling programs that use the GNU C Library. (We do not know exactly
how old, and some GNU extensions to C may be _de facto_ required. If you
are interested in helping us make this statement less vague, please
contact address@hidden)
Security related changes:
* The DNS stub resolver limits the advertised UDP buffer size to 1200 bytes,
to avoid fragmentation-based spoofing attacks (CVE-2017-12132).
* LD_LIBRARY_PATH is now ignored in binaries running in privileged AT_SECURE
mode to guard against local privilege escalation attacks
(CVE-2017-1000366).
* Avoid printing a backtrace from the __stack_chk_fail function since it is
called on a corrupt stack and a backtrace is unreliable on a corrupt stack
(CVE-2010-3192).
* A use-after-free vulnerability in clntudp_call in the Sun RPC system has
been
fixed (CVE-2017-12133).

mutex: Fix robust mutex lock acquire (Bug 21778)
65810f0ef05e8c9e333f17a44e77808b163ca298 fixed a robust mutex bug but
introduced BZ 21778: if the CAS used to try to acquire a lock fails, the
expected value is not updated, which breaks other cases in the loce
acquisition loop. The fix is to simply update the expected value with
the value returned by the CAS, which ensures that behavior is as if the
first case with the CAS never happened (if the CAS fails).
This is a regression introduced in the last release.
Tested on x86_64, i686, ppc64, ppc64le, s390x, aarch64, armv7hl.

microblaze: Resolve non-relocatable branch in pt-vfork.S (BZ#21779)
The relative branch directly to __libc_vfork results in an relocation
that cannot be resolved. Specifically a R_MICROBLAZE_64_PCREL relocation
is created for this branch, however for MicroBlaze R_MICROBLAZE_64_PCREL
type relocations symbols are not resolved. Additionally due to the
branch being located in the .text section the instruction cannot be
rewritten as the section is not writable, and causes a segfault at
runtime when loading libpthread.
To resolve this issue, ensure the branch is done using PLT. This removes
the need to modify the instruction and trades the R_MICROBLAZE_64_PCREL
for a more common R_MICROBLAZE_JUMP via the PLT.
[BZ #21779]
* sysdeps/unix/sysv/linux/microblaze/pt-vfork.S: Branch using PLT.

rwlock: Fix explicit hand-over (bug 21298)
Without this fix, the rwlock can fail to execute the explicit hand-over
in certain cases (e.g., empty critical sections that switch quickly between
read and write phases). This can then lead to errors in how __wrphase_futex
is accessed, which in turn can lead to deadlocks.

manual: Refactor documentation of CHAR_BIT.
This address@hidden @table is better defined with @deftypevr, since the
CHAR_BIT macro has @standards (being declared in a header), and @items
in @tables are not considered annotatable. Using @deftypevr
automatically includes the macro in the Variable and Constant Macro
Index and ensures its inclusion the Summary of Library Facilities.
@deftypevr is used to record the type of the macro so that it also
appears in the Summary.
The description is updated to mention a later POSIX requirement that
this macro have the value 8.
* manual/lang.texi (CHAR_BIT): Convert from an @table to an
@deftypevr. Change standard from ISO to C90. Mention the
POSIX.1-2001 requirement of the value 8.

Indian scripts: More fixes after the recent import.
After the recent import of month names from CLDRv31 (bug 21217,
commit c853f14) an import of abbreviated month names is also needed
to make sure they match the full forms.
In case of kok_IN CLDR does not provide the abbreviated month names
explicitly but uses full month names in such cases so abmon section
has been copied from mon.

tunables: Use direct syscall for access (BZ#21744)
The function maybe_enable_malloc_check, which is called by
__tunables_init, calls __access_noerrno. It isn't problem when
symbol is is in ld.so, which has a special version of __access_noerrno
without stack protector. But when glibc is built with stack protector,
maybe_enable_malloc_check in libc.a can't call the regular version of
__access_noerrno with stack protector.
This patch changes how Linux defines the __access_noerrno to be an
inline call instead and thus preventing defining different build
rules for ld/static and shared.

Avoid accessing corrupted stack from __stack_chk_fail [BZ #21752]
__libc_argv[0] points to address on stack and __libc_secure_getenv
accesses environment variables which are on stack. We should avoid
accessing stack when stack is corrupted.
This patch also renames function argument in __fortify_fail_abort
from do_backtrace to need_backtrace to avoid confusion with do_backtrace
from enum __libc_message_action.
[BZ #21752]
* debug/fortify_fail.c (__fortify_fail_abort): Don't pass down
__libc_argv[0] if we aren't doing backtrace. Rename do_backtrace
to need_backtrace.
* sysdeps/posix/libc_fatal.c (__libc_message): Don't call
__libc_secure_getenv if we aren't doing backtrace.

S390: fix sys/ptrace.h to make it includible again after asm/ptrace.h
sys/ptrace.h on S390 used to be includible both before and after
asm/ptrace.h, until commit b08a6a0dea63742313ed3d9577c1e2d83436b196
among other changes introduced PTRACE_SINGLEBLOCK enum constant which
is also defined in asm/ptrace.h as a macro, making sys/ptrace.h fail
to compile when included after asm/ptrace.h.
* sysdeps/unix/sysv/linux/s390/sys/ptrace.h [_LINUX_PTRACE_H ||
_S390_PTRACE_H]: Undefine all PTRACE_* macro constants defined
later as enum constants, except PTRACE_PEEKUSER, PTRACE_POKEUSER,
and PTRACE_SEIZE_DEVEL that are not defined by Linux headers.

PLT avoidance for __stack_chk_fail [BZ #7065]
Add a hidden __stack_chk_fail_local alias to libc.so,
and make sure that on targets which use __stack_chk_fail,
this does not introduce a local PLT reference into libc.so.
which unconditionally added
strong_alias (__stack_chk_fail, __stack_chk_fail_local)
defines __stack_chk_fail_local as an alias of __stack_chk_fail in libc.a.
There is no need to add stack_chk_fail_local.o to libc.a. We only need
to add stack_chk_fail_local.oS to libc_nonshared.a.
Tested on x86-64:
address@hidden build-x86_64-linux]$ nm libc.a | grep __stack_chk_fail

Disable single thread optimization for open_memstream
Single thread optimization is valid if at thread creation time the
optimization can be disabled. This is in principle true for all
stream objects that user code can access (and thus needs locking),
using the same internal list as fflush(0) uses. However in glibc
open_memstream is not on that list (BZ 21735) so the optimization
has to be disabled.

[ARM] Fix ld.so crash when built using Binutils 2.29
There is bug report that ld.so in GLIBC 2.24 built by Binutils 2.29 will
crash
on arm-linux-gnueabihf. This is confirmed, and the details is at:
https://sourceware.org/bugzilla/show_bug.cgi?id=21725.
As analyzed in the PR, the old code was with the assumption that assembler
won't set bit0 of thumb function address if it comes from PC-relative
instructions and the calculation can be finished during assembling. This
assumption however does not hold after PR gas/21458.
* sysdeps/arm/dl-machine.h (elf_machine_load_address): Also strip bit 0
of pcrel_address under Thumb mode.

powerpc64le: Iterate over all object suffixes when appending -mfloat128
On powerpc64le, the compilation of the files related to float128 support
requires the option -mfloat128 to be passed to gcc. However, not all
possible object suffixes were covered in the Makefile. This patch uses
$(all-object-suffixes) in all remaining rules.
Tested for powerpc64le.
* sysdeps/powerpc/powerpc64le/Makefile: Use $(all-object-suffixes)
to iterate over all possible object suffixes. Add a comment
explaining the use of sysdep-CFLAGS instead of CFLAGS.

Avoid backtrace from __stack_chk_fail [BZ #12189]
__stack_chk_fail is called on corrupted stack. Stack backtrace is very
unreliable against corrupted stack. __libc_message is changed to accept
enum __libc_message_action and call BEFORE_ABORT only if action includes
do_backtrace. __fortify_fail_abort is added to avoid backtrace from
__stack_chk_fail.
[BZ #12189]
* debug/Makefile (CFLAGS-tst-ssp-1.c): New.
(tests): Add tst-ssp-1 if -fstack-protector works.
* debug/fortify_fail.c: Include <stdbool.h>.

S390: Fix tst-ptrace-singleblock if kernel does not support
PTRACE_SINGLEBLOCK.
The request PTRACE_SINGLEBLOCK was introduced in Linux 3.15. Thus the
ptrace call
will fail on older kernels.
Thus the test is now testing PTRACE_SINGLEBLOCK with data argument pointing
to a
buffer on stack which is assumed to fail. If the request would be
interpreted as
PTRACE_GETREGS, then the ptrace call will not fail and the regs are written
to buf.
If we run with a kernel with support for PTRACE_SINGLEBLOCK a ptrace call
with
data=NULL, returns zero with no error. If we run with a kernel without
support for
PTRACE_SINGLEBLOCK a ptrace call with data=NULL reports an error.
In the latter case, the test is just continuing with PTRACE_CONT.
ChangeLog:
* sysdeps/unix/sysv/linux/s390/tst-ptrace-singleblock.c:
Support running on kernels without PTRACE_SINGLEBLOCK.

x86-64: Align the stack in __tls_get_addr [BZ #21609]
This change forces realignment of the stack pointer in __tls_get_addr, so
that binaries compiled by GCCs older than GCC 4.9:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=58066
continue to work even if vector instructions are used in glibc which
require the ABI stack realignment.
__tls_get_addr_slow is added to handle the slow paths in the default
implementation of__tls_get_addr in elf/dl-tls.c. The new __tls_get_addr
calls __tls_get_addr_slow after realigning the stack. Internal calls
within ld.so go directly to the default implementation of __tls_get_addr
because they do not need stack realignment.

Single threaded stdio optimization
Locking overhead can be significant in some stdio operations
that are common in single threaded applications.
This patch adds the _IO_FLAGS2_NEED_LOCK flag to indicate if
an _IO_FILE object needs to be locked and some of the stdio
functions just jump to their _unlocked variant when not. The
flag is set on all _IO_FILE objects when the first thread is
created. A new GLIBC_PRIVATE libc symbol, _IO_enable_locks,
was added to do this from libpthread.
The optimization can be applied to more stdio functions,
currently it is only applied to single flag check or single
non-wide-char standard operations. The flag should probably
be never set for files with _IO_USER_LOCK, but that's just a
further optimization, not a correctness requirement.
The optimization is valid in a single thread because stdio
operations are non-as-safe (so lock state is not observable
from a signal handler) and stdio locks are recursive (so lock
state is not observable via deadlock). The optimization is not
valid if a thread may be created while an stdio lock is taken
and thus it should be disabled if any user code may run during
an stdio operation (interposed malloc, printf hooks, etc).
This makes the optimization more complicated for some stdio
operations (e.g. printf), but those are bigger and thus less
important to optimize so this patch does not try to do that.

resolv: Automatically reload a changed /etc/resolv.conf file [BZ #984]
This commit enhances the stub resolver to reload the configuration
in the per-thread _res object if the /etc/resolv.conf file has
changed. The resolver checks whether the application has modified
_res and will not overwrite the _res object in that case.
The struct resolv_context mechanism is used to check the
configuration file only once per name lookup.

resolv: Mirror the entire resolver configuration in struct resolv_conf
This commit adds the remaining unchanging members (which are loaded
from /etc/resolv.conf) to struct resolv_conf.
The extended name server list is currently not used by the stub
resolver. The switch depends on a cleanup: The _u._ext.nssocks
array stores just a single socket, and needs to be replaced with
a single socket value.
(The compatibility gethostname implementation does not use the
extended addres sort list, either. Updating the compat code is
not worthwhile.)

This change uses the extended resolver state in struct resolv_conf to

resolver during name resolution.

resolv: Introduce struct resolv_conf with extended resolver state
This change provides additional resolver configuration state which
is not exposed through the _res ABI. It reuses the existing
initstamp field in the supposedly-private part of _res. Some effort
is undertaken to avoid memory safety issues introduced by applications
which directly patch the _res object.
With this commit, only the initstamp field is moved into struct
resolv_conf. Additional members will be added later, eventually
migrating the entire resolver configuration.

resolv: Introduce struct resolv_context [BZ #21668]
struct resolv_context objects provide a temporary resolver context
which does not change during a name lookup operation. Only when the
outmost context is created, the stub resolver configuration is
verified to be current (at present, only against previous res_init
calls). Subsequent attempts to obtain the context will reuse the
result of the initial verification operation.
struct resolv_context can also be extended in the future to store
data which needs to be deallocated during thread cancellation.

float128: Add signbit alternative for old compilers
In math/math.h, __MATH_TG will expand signbit to __builtin_signbit*,
e.g.: __builtin_signbitf128, before GCC 6. However, there has never
been a __builtin_signbitf128 in GCC and the type-generic builtin is
only available since GCC 6. For older GCC, this patch defines
__builtin_signbitf128 to __signbitf128, so that the internal function
is used instead of the non-existent builtin.
This patch also changes the implementation of __signbitf128, because
it was reusing the implementation of __signbitl from ldbl-128, which
calls __builtin_signbitl. Using the long double version of the
builtin is not correct on machines where _Float128 is ABI-distinct
from long double (i.e.: ia64, powerpc64le, x86, x86_84). The new
implementation does not rely on builtins when being built with GCC
versions older than 6.0.
The new code does not currently affect powerpc64le builds, because
only GCC 6.2 fulfills the requirements from configure. It might
affect powerpc64le builds if those requirements are backported to
older versions of the compiler. The new code affects x86_64 builds,
since glibc is supposed to build correctly with older versions of GCC.
Tested for powerpc64le and x86_64.

i386: Increase MALLOC_ALIGNMENT to 16 [BZ #21120]
GCC 7 changed the definition of max_align_t on i386:
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9b5c49ef97e63cc63f1ffa13baf771368105ebe2
As a result, glibc malloc no longer returns memory blocks which are as
aligned as max_align_t requires.
This causes malloc/tst-malloc-thread-fail to fail with an error like this
one:
error: allocation function 0, size 144 not aligned to 16
This patch moves the MALLOC_ALIGNMENT definition to <malloc-alignment.h>
and increases the malloc alignment to 16 for i386.

SPARC sys/ucontext.h namespace fixes (bug 21457).
This patch fixes various miscellaneous namespace issues in the SPARC
sys/ucontext.h header. These are similar to changes made previous to
other sys/ucontext.h headers, where the SPARC header was excluded from
those previous patches because of its complexity.
Tested for SPARC with build-many-glibcs.py.

posix: Improve default posix_spawn implementation
This patch improves the default posix implementation of posix_spawn{p}
and align with Linux one. The main idea is to fix some issues already
fixed in Linux code, and deprecated vfork internal usage (source of
various bug reports). In a short:
- It moves POSIX_SPAWN_USEVFORK usage and sets it a no-op. Since
the process that actually spawn the new process do not share
memory with parent (with vfork), it fixes BZ#14750 for this
implementation.
- It uses a pipe to correctly obtain the return upon failure
of execution (BZ#18433).
- It correctly enable/disable asynchronous cancellation (checked
on ptl/tst-exec5.c).
- It correctly disable/enable signal handling.
Using this version instead of Linux shows only one regression,
posix/tst-spawn3, because of pipe2 usage which increase total
number of file descriptor.
* sysdeps/posix/spawni.c (__spawni_child): New function.
(__spawni): Rename to __spawnix.

Support _Float128 in tgmath.h.
This patch adds tgmath.h support for _Float128, so eliminating the
awkward caveat in NEWS about the type not being supported there. This
does inevitably increase the size of macro expansions (which grows
particularly fast when you have nested calls to tgmath.h macros), but
only when _Float128 is supported and the declarations of _Float128
interfaces are visible; otherwise the expansions are unchanged.
Tested for x86_64 and arm.

Use clog10 not __clog10 in tgmath.h log10 macro.
As a GNU extension, for _GNU_SOURCE glibc's complex.h provides a
clog10 function and tgmath.h supports complex arguments to the log10
macro. However, tgmath.h uses __clog10 not clog10 in defining the
macro.
There is no namespace reason (ignoring the block-scope namespace
issues that would apply equally to *every* function called by tgmath.h
macros) for using __clog10 here, since this is only for _GNU_SOURCE so
clog10 is always visible when this macro definition is used.
Furthermore, __clog10f128 is not exported, so supporting _Float128 in
tgmath.h implies using clog10 not __clog10 there. (__clog10 and
clog10 aren't used in libstdc++ either, although that library would
have a good case for using the __clog10 reserved-namespace export: the
standard C++ library includes log10 of a complex number.) This patch
duly changes the header to use clog10, and enables tests of the macro
for complex arguments.
Tested for x86_64.
* math/tgmath.h [__USE_GNU] (log10): Use clog10 not __clog10.
* math/gen-tgmath-tests.py (Tests.add_all_tests): Test log10 for
complex arguments.

Fix tgmath.h totalorder, totalordermag return type (bug 21687).
The tgmath.h totalorder and totalordermag macros wrongly return a

including enabling tests of those functions from gen-tgmath-tests.py.
Tested for x86_64.

Simplify tgmath.h for integer return types.
The tgmath.h macros for function with integer return types generate
unnecessary casts to the return type. Since in those cases the return
type does not depend on the argument type, all the cases in the
conditional expressions already have the right type, and no casts are
needed; this patch removes them.

Remove NO_LONG_DOUBLE conditionals in libm tests (bug 21607).
As noted in bug 21607, NO_LONG_DOUBLE conditionals in libm tests are
no longer effective. For most this is harmless - they were only
present because of long double functions not being declared with _LIBC
defined, and _LIBC is no longer defined for building most tests. For
the few where this is actually relevant to the test, testing
LDBL_MANT_DIG > DBL_MANT_DIG is more appropriate as that limits the
test to public APIs. This patch fixes the tests accordingly.
Tested for x86_64 and arm.

Add more thorough generated tgmath.h test.
This patch adds a more thorough test of tgmath.h macros, verifying
both the return type and the function called for all the cases of
valid argument types. (Cases with current problems - I've just filed
four bugs - are disabled or omitted pending fixing those problems.)
The test uses a Python generator (works with both Python 2 and 3) to
generate a C file which is then built and run as a test in the usual
way (and that C file includes its own dummy definitions of libm
functions similar to existing tgmath.h tests). The motivation is to
make it easier to add tests of tgmath.h for _Float128 when adding
tgmath.h support for that type; the _FloatN / _FloatNx support is
present in the script, but disabled until the tgmath.h support is
written.
Tested for x86_64, and for arm to check things in the long double =
double case. (In that case, it's OK to call either double or long
double functions when the selected type is double or long double, as
long as the return type of the macro is exactly correct.)

Require binutils 2.25 or later to build glibc.
This patch implements a requirement of binutils >= 2.25 (up from 2.22)
to build glibc. Tests for 2.24 or later on x86_64 and s390 are
removed. It was already the case, as indicated by buildbot results,
that 2.24 was too old for building tests for 32-bit x86 (produced
internal linker errors linking elf/tst-gnu2-tls1mod.so). I don't know
if any configure tests for binutils features are obsolete given the
increased version requirement.

Miscellaneous sys/ucontext.h namespace fixes (bug 21457).
This patch fixes various miscellaneous namespace issues in
sys/ucontext.h headers.
Some struct tags are removed where the structs also have *_t typedef
names, while other struct tags without such names are renamed to start
__; the changes are noted in NEWS as they can affect C++ name mangling
(although there seems to be little if any external use of these types,
at least based on checking codesearch.debian.net). For powerpc,
pointers to struct pt_regs (not defined in this header) are changed to
point to struct __ctx(pt_regs), so in the __USE_MISC case those struct
fields continue to point to the existing struct pt_regs type for
maximum compatibility, while when that's a namespace issue they point
to a struct __pt_regs type which is always an incomplete struct.
Tested for affected architectures with build-many-glibcs.py.
[BZ #21457]
* sysdeps/unix/sysv/linux/m68k/sys/ucontext.h (fpregset_t): Remove
struct tag.
* sysdeps/unix/sysv/linux/mips/sys/ucontext.h (fpregset_t):
Likewise.
* sysdeps/unix/sysv/linux/nios2/sys/ucontext.h (mcontext_t):
Likewise.
* sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h (pt_regs):
Declare struct type with __ctx.
[__WORDSIZE != 32] (mcontext_t): Use __ctx with pt_regs struct
tag.
(ucontext_t) [__WORDSIZE == 32]: Use __ctx with pt_regs struct tag
and regs field name.

Fix elf/loadtest.c build with GCC 8.
Building the testsuite with current GCC mainline fails with:
loadtest.c: In function 'main':
loadtest.c:76:3: error: macro expands to multiple statements
[-Werror=multistatement-macros]
for (map = MAPS; map != NULL; map = map->l_next) \
^
loadtest.c:165:2: note: in expansion of macro 'OUT'
OUT;
^~~
loadtest.c:164:7: note: some parts of macro expansion are not guarded by
this 'if' clause
if (debug)
^~
This seems like a genuine bug, although fairly harmless; it means the
fflush call in the OUT macro is unconditional instead of being inside
the conditional as presumably intended. This patch makes this macro
use do { } while (0) to avoid the problem.
Tested for x86_64 (testsuite), and with build-many-glibcs.py for
aarch64-linux-gnu with GCC mainline.
* elf/loadtest.c (OUT): Define using do { } while (0).

Fix strftime build with GCC 8.
Building with current GCC mainline fails with:
strftime_l.c: In function '__strftime_internal':
strftime_l.c:719:4: error: macro expands to multiple statements
[-Werror=multistatement-macros]
digits = d > width ? d : width; \
^
strftime_l.c:1260:6: note: in expansion of macro 'DO_NUMBER'
DO_NUMBER (1, tp->tm_year + TM_YEAR_BASE);
^~~~~~~~~
strftime_l.c:1259:4: note: some parts of macro expansion are not guarded by
this 'else' clause
else
^~~~
In fact this particular instance is harmless; the code looks like:
if (modifier == L_('O'))
goto bad_format;
else
DO_NUMBER (1, tp->tm_year + TM_YEAR_BASE);
and because of the goto, it doesn't matter that part of the expansion
isn't under the "else" conditional. But it's also clearly bad style
to rely on that. This patch changes DO_NUMBER and DO_NUMBER_SPACEPAD
to use do { } while (0) to avoid such problems.
Tested (full testsuite) for x86_64 (GCC 6), and with
build-many-glibcs.py with GCC mainline, in conjunction with my libgcc
patch <https://gcc.gnu.org/ml/gcc-patches/2017-06/msg02032.html>.
* time/strftime_l.c (DO_NUMBER): Define using do { } while (0).
(DO_NUMBER_SPACEPAD): Likewise.

[ARM] Optimise memchr for NEON-enabled processors
This patch provides an optimised implementation of memchr using NEON
instructions to improve its performance, especially with longer search
regions.
This gave an improvement in performance against the Thumb2+DSP optimised
code,
with more significant gains for larger inputs. The NEON code also wins in
cases
where the input is small (less than 8 bytes) by defaulting to a simple
byte-by-byte search. This avoids the overhead imposed by filling two
quadword
registers from memory.
* sysdeps/arm/armv7/multiarch/Makefile: Add memchr_neon to
sysdep_routines.
* sysdeps/arm/armv7/multiarch/ifunc-impl-list.c: Add define for
__memchr_neon.
Add ifunc definitions for __memchr_neon and __memchr_noneon.
* sysdeps/arm/armv7/multiarch/memchr.S: New file.
* sysdeps/arm/armv7/multiarch/memchr_impl.S: Likewise.
* sysdeps/arm/armv7/multiarch/memchr_neon.S: Likewise.
Testing done: Ran regression tests for arm-none-linux-gnueabihf as well as a
full toolchain bootstrap. Benchmark tests were ran on ARMv7-A and ARMv8-A
hardware targets.

S390: Use cu21 instruction for converting from utf16 to utf8.
This patch adds an ifunc variant to use the cu instruction on arch12 CPUs.
This new ifunc variant can be built if binutils support z13 vector
instructions. At runtime, HWCAP_S390_VXE decides if we can use the
cu21 instruction.
ChangeLog:
* sysdeps/s390/utf8-utf16-z9.c (__to_utf8_loop_vx_cu):
Use vector and cu21 instruction.
* sysdeps/s390/multiarch/utf8-utf16-z9.c:

S390: Save and restore r12 in TLS_IE macro.
The testcases elf/tst-tls1-static and elf/tst-tls2-static
are failing on s390 if gcc is configured with --enable-default-pie.
According to binutils, there are only four valid cases for IE -> LE
transition:
lg %rx,(0,%ry) -> sllg %rx,%ry,0
lg %rx,(%ry,0) -> sllg %rx,%ry,0
lg %rx,(%ry,%r12) -> sllg %rx,%ry,0
lg %rx,(%r12,%ry) -> sllg %rx,%ry,0
Thus I've adjusted the TLS_IE macro in s390 tls-macros.h files in PIC case
in order to use r12 for the address of global offset table.
The adjusted macro definition is not used if gcc is not configured with
--enable-default-pie.
ChangeLog:
* sysdeps/s390/s390-32/tls-macros.h (TLS_IE): Use r12 for GOT address.
* sysdeps/s390/s390-64/tls-macros.h (TLS_IE): Likewise.

resolv: Avoid timeouts in test-resolv-res-init, test-resolv-res_init-thread
Some Linux kernels have very aggressive ICMP rate limiting on the
loopback interface. This commit introduces a minimal echoing DNS server
inside the network namespace, so that there is no need for ICMP error
messages anymore.

resolv: Call _res_hconf_init from __res_vinit
Many callers of __res_maybe_init also call _res_hconf_init.
Additional calls to the latter do not hurt because the function
does its work only once. (/etc/hosts.conf is not reloaded or
even checked for changes.) This means that we can simplify the
code by calling _res_hconf_init directly from __res_vinit.

Add float128 support for ia64.
This patch enables float128 support for ia64, so that all the
configurations where GCC supports _Float128 / __float128 as an
ABI-distinct type now have glibc support as well. bits/floatn.h
declares the support to be available for GCC 4.4 and later, which is
when the libgcc support was added. The removal of
sysdeps/ia64/fpu/k_rem_pio2.c is because the generic k_rem_pio2.c
defines a function required by the float128 code.
Tested (compilation only) with build-many-glibcs.py for ia64 (GCC 6
and GCC 7).
Given how long it is since libm-test-ulps has been updated for ia64, I
think truncating the file and regenerating it from scratch would be a
good idea when doing a regeneration to add float128 ulps. I expect
various ia64 libm issues (at least some already filed in Bugzilla) to
result in test failures even after ulps regeneration, but hopefully
the float128 code will pass tests as it's the same as used on other
architectures.

Rename struct ucontext tag (bug 21457).
The ucontext_t type has a tag struct ucontext. As with previous such
issues for siginfo_t and stack_t, this tag is not permitted by POSIX
(is not in a reserved namespace), and so namespace conformance means
breaking C++ name mangling for this type.
In this case, the type does need to have some tag rather than just a
typedef name, because it includes a pointer to itself. This patch
uses struct ucontext_t as the new tag, so the type is mangled as
ucontext_t (the POSIX *_t reservation applies in all namespaces, not
just the namespace of ordinary identifiers). Another reserved name
such as struct __ucontext could of course be used.
Because of other namespace issues, this patch does not by itself fix
bug 21457 or allow any XFAILs to be removed.
Tested for x86_64, and with build-many-glibcs.py.

Add float128 support for x86_64, x86.
This patch enables float128 support for x86_64 and x86. All GCC
versions that can build glibc provide the required support, but since
GCC 6 and before don't provide __builtin_nanq / __builtin_nansq, sNaN
tests and some tests of NaN payloads need to be disabled with such
compilers (this does not affect the generated glibc binaries at all,
just the tests). bits/floatn.h declares float128 support to be
available for GCC versions that provide the required libgcc support
(4.3 for x86_64, 4.4 for i386 GNU/Linux, 4.5 for i386 GNU/Hurd);
compilation-only support was present some time before then, but not
really useful without the libgcc functions.
fenv_private.h needed updating to avoid trying to put _Float128 values
in registers. I make no assertion of optimality of the
math_opt_barrier / math_force_eval definitions for this case; they are
simply intended to be sufficient to work correctly.
Tested for x86_64 and x86, with GCC 7 and GCC 6. (Testing for x32 was
compilation tests only with build-many-glibcs.py to verify the ABI
baseline updates. I have not done any testing for Hurd, although the
float128 support is enabled there as for GNU/Linux.)

Call exit directly in clone (BZ #21512)
On aarch64, alpha, arm, hppa, mips, nios2, powerpc, sh, sparc, tile,
and x86_64 the clone syscall jumps to _exit after the child execution
and the function ends the process execution by calling exit_group.
This behavior have a small issue where threads created with
CLONE_THREAD using clone syscall directly will eventually exit the
whole group altogether instead of just the thread created. Also,
s390, microblaze, ia64, i386, and m68k differs by calling exit
syscall directly.
This patch changes all architectures to call the exit syscall
directly, as for s390, microblaze, ia64, i386, and m68k. This do not
have change glibc internal behavior in any sort, since the only
usage of clone implementation in posix_spawn calls _exit directly
in the created child (fork uses a direct call to clone).
Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu,
powerpc-linux-gnu, powerpc64le-linux-gnu, sparc64-linux-gnu,
and sparcv9-linux-gnu.

Clean pthread functions namespaces for C11 threads
This patch adds internal definition (through {libc_}hidden_{proto,def}) and
also change some strong to weak alias for symbols that might be used by C11
threads implementations.
The patchset should not change libc/libpthread functional, although object
changes are expected (since now internal symbols are used instead) and final
exported symbols through GLIBC_PRIVATE is also expanded (to cover libpthread
usage of __mmap{64}, __munmap, __mprotect).

Make libm-test-support code clear exceptions after each test.
The libm-test-support code clears exceptions at the end of
test_exceptions. However, it's possible that exceptions get raised as
part of the subsequent checks on the results of the function being
tested, and such exceptions then carry through to the next test run
and can cause that to fail spuriously. In particular, it's possible
for the ulps calculation to raise exceptions in some cases. This
patch puts exception clearing at the end of each of the check_*
functions, alongside errno clearing, to avoid one test affecting the
next in that way.
Tested for x86_64 (in conjunction with float128 patches).

Avoid localplt issues from x86 fereaiseexcept inline.
Building for x86_64 with float128 support, I get a localplt test
failure from lrintf128 calling feraiseexcept.
The problem is that an inline optimized version of feraiseexcept calls
__feraiseexcept_renamed in cases where it doesn't completely expand
inline, and that in turn is redirected to feraiseexcept for a library
call, so meaning the redirection of feraiseexcept to
__GI_feraiseexcept inside libm is lost for that call.
This patch fixes the problem by moving the redirect to an internal
header in the _LIBC case, with the internal header using
__GI_feraiseexcept where appropriate.
Tested for x86_64 (in conjunction with float128 patches).

x86-64: memcmp-avx2-movbe.S needs saturating subtraction [BZ #21662]
This code:
L(between_2_3):
/* Load as big endian with overlapping loads and bswap to avoid
branches. */
movzwl -2(%rdi, %rdx), %eax
movzwl -2(%rsi, %rdx), %ecx
shll $16, %eax

movzwl (%rdi), %edi
movzwl (%rsi), %esi
orl %edi, %eax
orl %esi, %ecx
bswap %eax
bswap %ecx
subl %ecx, %eax
ret
needs a saturating subtract because the full register is used.
With this commit, only the lower 24 bits of the register are used,
so a regular subtraction suffices.
The test case change adds coverage for these kinds of bugs.

This patch makes math-tests.h, as used to describe support of given

distinguishing _Float128 from long double. This is needed for x86_64,
where if building with GCC 6 or earlier there is no __builtin_nansq,
so no way to get a signaling NaN of _Float128 type, so associated
tests cannot be run (although glibc itself works fine, as there is
never any need to create such an sNaN with a built-in function inside
glibc).

Fix float128_private.h redefinition of SET_RESTORE_ROUNDL.
As with other long double identifiers, float128_private.h has a
redefinition of SET_RESTORE_ROUNDL. However, that redefinition is
broken, since this is a macro with one argument being defined to take
no arguments. This patch fixes the redefinition. (x86_64 needs the
redefinition because SET_RESTORE_ROUNDL only changes the x87 rounding
mode, whereas _Float128 arithmetic uses the SSE rounding mode instead
on x86_64.)

Make float128_private.h work with generic ieee754.h.
float128_private.h redefines ieee754.h identifiers ieee854_long_double
and IEEE854_LONG_DOUBLE_BIAS to map them to identifiers from
ieee754_float128.h.
This causes problems when ieee754.h is included after
float128_private.h and it's a version of ieee754.h that also defines
those identifiers; specifically, sysdeps/ieee754/ieee754.h, which
defines those identifiers for the x86 extended format. This patch
fixes this by ensuring an include of ieee754.h from float128_private.h
before the redefinitions.

Correct min_of_type handling of _Float128.
The math_private.h macro min_of_type has broken _Float128 handling:
instead of passing its type argument to the key __EXPR_FLT128 macro,
it passes x, which is not a macro argument but whatever variable
called x happens to be visible in the calling function. If that
variable has the wrong type, the wrong one of long double and
_Float128 can get chosen. In particular, this applies to some
_Complex long double functions (where x happens to have type _Complex
long double, resulting in min_of_type returning a _Float128 value when
it should return a long double value). For some reason, this only
caused test failures for me on x86_64 with GCC 6 but not GCC 7 (I
suspect it triggers known bugs in conversions from x86 long double to
_Float128 that are present in GCC 6's soft-fp).
Tested for x86_64 (in conjunction with float128 patches).

Make errno-setting libm templates include errno.h.
Various type-generic libm wrapper templates, as used for float128, set
errno but do not include errno.h. I presume they must get an implicit

an implicit include on x86_64. This patch adds the missing includes

Fix float128 uses of xlocale.h.
Three float128 files still include xlocale.h after it was removed. I
don't know why this didn't cause problems for powerpc64le float128
testing; it did cause problems for my x86_64 float128 testing. This
patch changes the includes to use bits/types/locale_t.h.
Tested for x86_64 (in conjunction with float128 patches).

benchtests: New script to parse memcpy results
Read the memcpy results in json and print out the results in tabular

of the implementations.
The format of the output is extensible enough to allow this kind of
analysis to be done on other string functions as well.

Describe remainder as primary and drem as alternative in the manual
In preparation for the documentation of _FloatN and _FloatNx variants of
the remainder function, this patch changes the descriptions of remainder
and drem, so that remainder is described as primary and drem as an
alternative name for the same functionality.
* manual/arith.texi (Remainder Functions): Describe remainder as
primary and drem as an alternative name. Change the comment on
remainder to ISO, since it is defined in ISO C99.

Provide an additional macro expansion for F128 in stdlib/tst-strtod.h
The macro F128 in stdlib/tst-strtod.h is defined to provide the literal
suffix for _Float128 constants. It uses the macro __f128 (), which is
defined in bits/floatn.h to provide the correct literal suffix depending on
what is provided by the compiler.
However, F128 was not being expanded and only worked correctly, when
compiling with GCC 7 (or greater), since F128 is the literal suffix itself.
This patch adds an additional macro expansion so that the macro F128
expands to the correct literal suffix on older compilers.
* stdlib/tst-strtod.h (MMFUNC): New macro to provide an addition
macro expansion.
(GEN_TEST_STRTOD_FOREACH): Use MMFUNC for _Float128.

Implement allocation buffers for internal use
This commit adds fixed-size allocation buffers. The primary use
case is in NSS modules, where dynamically sized data is stored
in a fixed-size buffer provided by the caller.
Other uses include a replacement of mempcpy cascades (which is
safer due to the size checking inherent to allocation buffers).

x86-64: Implement strcmp family IFUNC selectors in C
Implement strcmp family IFUNC selectors in C.
All internal calls within libc.so can use IFUNC on x86-64 since unlike
x86, x86-64 supports PC-relative addressing to access the GOT entry so
that it can call via PLT without using an extra register. For libc.a,
we can't use IFUNC for functions which are called before IFUNC has been
initialized. Use IFUNC internally reduces the icache footprint since
libc.so and other codes in the process use the same implementations.
This patch uses IFUNC for strcmp family functions within libc.

Fix tile SA_* conditions for POSIX.1:2008 (bug 21622).
As shown by conform/ tests once the remaining namespace issues are
fixed, the tile bits/sigaction.h fails to declare SA_RESETHAND,
SA_RESTART and SA_NODEFER for non-XSI POSIX.1:2008 as other versions
do. Those constants were moved from XSI to Base in the 2008 edition
of POSIX. This patch fixes the conditions to match other versions of
this header.
Tested (compilation only) for tilegx-linux-gnu with
build-many-glibcs.py.

posix: Add invalid flags test for p{write,read}v2
This patch add an extra test for passing invalid flags and check its

Factor out shared definitions from bits/signum.h.
Many of the things defined by bits/signum.h are invariant across all
supported operating systems. This patch factors out all of them to a
new header bits/signum-generic.h, which each bits/signum.h will include
and then override whichever things need adjustment. Normally that will
mean, at most, adding or changing a few signal numbers.
A user-visible side effect is that the obsolete signal constant SIGUNUSED
(which is an alias for SIGSYS on all platforms that define it) is no
longer exposed by any version of bits/signum.h.
A side effect only relevant to glibc hackers is that _NSIG is now defined
in terms of __SIGRTMAX, instead of the other way around. This is because
__SIGRTMAX varies from platform to platform, but _NSIG==__SIGRTMAX+1 is
true universally. If your platform doesn't support realtime signals,
leave __SIGRTMAX equal to __SIGRTMIN.
I also added a Linux-specific test to make sure that our signal constants
match the ones in <asm/signal.h>, since we can't use that header (it's
not even vaguely namespace-clean).
* bits/signum-generic.h: Renamed from bits/signum.h.
Add proper multiple include guard and misuse check.
Define __SIGRTMIN = __SIGRTMAX = 32, and define _NSIG = __SIGRTMAX+1.
Move definition of SIGIO to "archaic names for compatibility" section.

Use locale_t, not __locale_t, throughout glibc
<locale.h> is specified to define locale_t in POSIX.1-2008, and so are
all of the headers that define functions that take locale_t arguments.
Under _GNU_SOURCE, the additional headers that define such functions
have also always defined locale_t. Therefore, there is no need to use
__locale_t in public function prototypes, nor in any internal code.

Rename xlocale.h to bits/types/__locale_t.h.
xlocale.h is already a single-type micro-header, defining struct
__locale_struct and the typedefs __locale_t and locale_t. This patch
brings it into the bits/types/ scheme: there are now
bits/types/__locale_t.h which defines only __locale_struct and
__locale_t, and bits/types/locale_t.h which defines locale_t as well
as the other two. None of *our* headers need __locale_t.h, but it
appears to me that libstdc++ could make use of it.
There are a lot of external uses of xlocale.h, but all the uses I
checked had an autoconf test or equivalent for its existence. It has
never been available from other C libraries, and it has always
contained a comment reading "This file is not standardized, don't rely
on it, it can go away without warning" so I think dropping it is
pretty safe.
I also took the opportunity to clean up comments in various public
header files that still talk about the *_l interfaces as though they
were completely nonstandard. There are a few of them, notably the
strtoX_l and wcstoX_l families, that haven't been standardized, but
the bulk are in POSIX.1-2008.
* locale/xlocale.h: Rename to...
* locale/bits/types/__locale_t.h: ...here. Adjust commentary.
Only define struct __locale_struct and __locale_t, not locale_t.
* locale/bits/types/locale_t.h: New file; define locale_t here.
* locale/Makefile (headers): Update to match.
* include/xlocale.h: Delete wrapper.
* include/bits/types/__locale_t.h: New wrapper.

the functions that take locale_t arguments.

Consolidate Linux openat implementation
This patch consolidates the open Linux syscall implementation on
sysdeps/unix/sysv/linux/open{64}.c. The changes are:
1. Remove wordsize-64 openat{64}.
2. For architetures that define __OFF_T_MATCHES_OFF64_T openat64
will be default one with alias to required symbols. Otherwise
openat64 will pass the required O_LARGEFILE flag on syscall.
Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,
arch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.
* sysdeps/unix/sysv/linux/openat.c (__libc_openat): Build only

tunables: Add IFUNC selection and cache sizes
The current IFUNC selection is based on microbenchmarks in glibc. It
should give the best performance for most workloads. But other choices
may have better performance for a particular workload or on the hardware
which wasn't available at the selection was made. The environment
variable, GLIBC_TUNABLES=glibc.tune.ifunc=-xxx,yyy,-zzz...., can be used
to enable CPU/ARCH feature yyy, disable CPU/ARCH feature yyy and zzz,
where the feature name is case-sensitive and has to match the ones in
cpu-features.h. It can be used by glibc developers to override the
IFUNC selection to tune for a new processor or improve performance for
a particular workload. It isn't intended for normal end users.
NOTE: the IFUNC selection may change over time. Please check all
multiarch implementations when experimenting.
Also, GLIBC_TUNABLES=glibc.tune.x86_non_temporal_threshold=NUMBER is
provided to set threshold to use non temporal store to NUMBER,
GLIBC_TUNABLES=glibc.tune.x86_data_cache_size=NUMBER to set data cache
size, GLIBC_TUNABLES=glibc.tune.x86_shared_cache_size=NUMBER to set
shared cache size.

Improve math benchmark infrastructure
Improve support for math function benchmarking. This patch adds
a feature that allows accurate benchmarking of traces extracted
from real workloads. This is done by iterating over all samples
rather than repeating each sample many times (which completely
ignores branch prediction and cache effects). A trace can be
added to existing math function inputs via
"## name: workload-<name>", followed by the trace.

Require GCC 4.9 or later for building glibc.
This patch makes configure require GCC 4.9 or later for building
glibc, and documents that requirement. Requiring GCC 4.9 or later
allows use of _Generic (as in tzcode). It would allow <stdatomic.h>
and _Atomic to be used as well if desired, although we need to avoid
any libatomic dependencies on any platforms. This patch is explicitly
the minimum to implement a new version requirement, with any
consequent cleanups of conditional code (not in installed headers or
files shared with gnulib etc.) to be done separately.

S390: Sync ptrace.h with kernel. [BZ #21539]
This patch removes PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS
and PTRACE_SETFPREGS as these requests does not exist on s390 kernel.
But the kernel has support for PTRACE_SINGLEBLOCK,
PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA, PTRACE_POKEUSR_AREA,
PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE, PTRACE_DISABLE_TE and
PTRACE_TE_ABORT_RAND. Thus those are defined now.
The current kernel s390 specific ptrace.h file also defines
PTRACE_PEEKTEXT_AREA, PTRACE_PEEKDATA_AREA, PTRACE_POKETEXT_AREA,
PTRACE_POKEDATA_AREA, PTRACE_PEEK_SYSTEM_CALL, PTRACE_POKE_SYSTEM_CALL
and PTRACE_PROT, but those requests are not supported.
Thus those defines are skipped in glibc ptrace.h.
There were old includes of ptrace.h in sysdeps/s390/fpu/fesetenv.c.
The ptrace feature isn't used there anymore, thus I removed the includes.
Before this patch, <glibc>/sysdeps/unix/sysv/linux/s390/sys/ptrace.h
uses ptrace-request 12 for PTRACE_GETREGS,
but <kernel>/include/uapi/linux/ptrace.h uses 12 for PTRACE_SINGLEBLOCK.
The s390 kernel has never had support for PTRACE_GETREGS!
Thus glibc ptrace.h is adjusted to match kernel ptrace.h.
The new s390 specific test ensures, that PTRACE_SINGLEBLOCK defined
in glibc works as expected. If the kernel would interpret it as
PTRACE_GETREGS, then the testcase will not make any progress
and will time out.
ChangeLog:

clear this obsolescent function should be declared by default).

Fix signal stack namespace (bug 21584).
In POSIX.1:2008, various signal stack symbols - sigaltstack, SS_*,

visible for non-XSI POSIX. This patch fixes the conditionals, leaving
the symbols available for __USE_MISC as it seems likely some of them
are widely used and should be visible by default. (Note that stack_t
is *not* XSI-shaded and so the conditionals on that are correctly
unchanged.)

Define struct rusage in sys/wait.h when required (bug 21575).
Some older standards (XPG4.2 through POSIX.1:2001, XSI only) require
sys/wait.h to include the definition of struct rusage. This is
missing in glibc.
This patch adds the required definition. struct rusage is moved to a
new header bits/types/struct_rusage.h to avoid bringing in the whole
of sys/resource.h (although the standards in question do allow the
whole of sys/resource.h to be brought in). In the five
bits/resource.h headers, the only variation between the definitions of
struct rusage is that the sysdeps/unix/sysv/linux version is prepared
for x32 (by having anonymous unions with __syscall_slong_t fields) and
the others are not. Thus, this version is suitable for use
generically (everything other than x32 simply has __syscall_slong_t

S390: Fix build with gcc configured with --enable-default-pie. [BZ #21537]
Building glibc with gcc configured with --enable-default-pie failed on s390
due to assembler messages:
../sysdeps/unix/sysv/linux/s390/s390-32/__makecontext_ret.S:44:
Error: junk at end of line, first unrecognized character is `@'
HIDDEN_JUMPTARGET was expanded to address@hidden@GOTOFF.
If SHARED is not defined, HIDDEN_JUMPTARGET is defined to JUMPTARGET
in sysdeps/s390/s390-32/sysdep.h. There it expanded to address@hidden
in non SHARED case as PIC is defined if gcc is configured with
--enable-default-pie. Thus I've changed the "ifdef PIC" to "ifdef SHARED"
as we do not want PLTs in the static obj files. I've also changed this
in sysdeps/s390/s390-64/sysdep.h.
I've also adjusted sysdeps/unix/sysv/linux/s390/s390-32/__makecontext_ret.S.
If glibc is configured with --disable-hidden-plt, then NO_HIDDEN is defined.
In SHARED case HIDDEN_JUMPTARGET would be expanded to address@hidden@GOTOFF
instead of address@hidden
Now we jump to:
- __GI_exit if SHARED is defined
- address@hidden if SHARED and NO_HIDDEN is defined
- exit if both are not defined.
On s390 31bit we have to setup GOT pointer in r12 if we use a PLT stub.
Therefore I use SYSCALL_PIC_SETUP from sysdep.h and added the missing
semicolons.
ChangeLog:
[BZ #21537]
* sysdeps/s390/s390-32/sysdep.h (JUMPTARGET, SYSCALL_PIC_SETUP):
Check SHARED instead of PIC.
(SYSCALL_PIC_SETUP): Add missing semicolons.
* sysdeps/s390/s390-64/sysdep.h (JUMPTARGET, SYSCALL_PIC_SETUP):
Check SHARED instead of PIC.

s390: optimize syscall function
Since kernel 2.6.0 all Linux version accept the system call number
in register 1 for svc 0. There is no need to have special handling
that uses EX for system calls < 256. This will simplify and speed
up that code.
A microbenchmark doing "syscall(__NR_getpid);" in a loops gets faster
by ~12%.

code by always using SVC 0 instead of EX.

Update timezone code from tzcode 2017b.
This patch updates files coming from tzcode to the versions in tzcode
2017b. A couple of changes to other glibc code are needed.
time/tzset.c was using the SECSPERDAY macro from tzfile.h, which no
longer defines that macro, so a local definition is added to tzset.c.
Because timezone/private.h now defines the _ macro whenever
HAVE_GETTEXT is true, even if it was previously defined, it is also
necessary to avoid a conflict with the definition in
include/libintl.h. Defining _ISOMAC is the obvious way to avoid such
internal definitions being visible, together with defining TZ_DOMAIN
so that zic and zdump continue to get the messages from the libc
domain as desired. However, zic and zdump rely on PKGVERSION and
REPORT_BUGS_TO from config.h, which is not included by default with
_ISOMAC, so -include config.h needs adding to the options for these
programs as well. Together those changes allow unmodified tzcode
2017b sources to work in glibc.
Tested for x86_64.

manual: Replace summary.awk with summary.pl.
The Summary is now generated from @standards, and syntax-checking is
performed. If invalid @standards syntax is detected, summary.pl will
fail, reporting all errors. Failure and error reporting is disabled
for now, however, since much of the manual is still incomplete
wrt. header and standards annotations.
Note that the sorting order of the Summary has changed; summary.pl
respects the locale, like summary.awk did, but the use of LC_ALL=C is
introduced in the Makefile. Other notable deviations are improved
detection of the annotated elements' names, which are used for
sorting, and improved detection of the @node used to reference into
the manual. The most noticeable difference in the rendered Summary is
that entries may now contain multiple lines, one for each header and
standard combination.
summary.pl accepts a `--help' option, which details the expected
syntax of @standards. If errors are reported, the user is directed to
this feature for further information.

manual: Create empty placeholder macros for @standards.
Header and standards annotations are slated for standardization,
including being rendered in the description of functions, variables,
etc. (elements), and eventually required. This commit adds @standards
dummy macros so we can convert all existing annotations to the new
framework while maintaining the rendered status quo.
There needs to be a way to disambiguate annotations in lists of @*x
elements, where a common description is shared but some elements may
have different headers or standards. The @standardsx macro fills this
role by accepting an additional parameter: the name of the annotated
element.
* manual/macros.texi (@standards): New macro. Provide
placeholder for header and standards annotations.
(@standardsx): New macro. Likewise, for lists of @*x
elements.

x86-64: Implement strcspn/strpbrk/strspn IFUNC selectors in C

Enable tunables by default
All of the major architectures are adopting tunables as a way to add
tuning to the library, from hwcap_mask for aarch64 to HLE for s390 and
ifunc and cache geometry for x86. Given this adoption and the fact
that we don't want additional tuning knobs to be added outside of
tunables, it makes sense to enable tunables by default using this
trivial patch.
Smoke tested on x86 to ensure that tunables code was built without
specifying it as a configure flag. I have kept it as --enabled and
not changed it to --disable since we want to still keep the option of
different kinds of front-ends for tunables.
* configure.ac(--enable-tunables): Enable by default.

nptl: Invert the mmap/mprotect logic on allocated stacks (BZ#18988)
Current allocate_stack logic for create stacks is to first mmap all
the required memory with the desirable memory and then mprotect the
guard area with PROT_NONE if required. Although it works as expected,
it pessimizes the allocation because it requires the kernel to actually
increase commit charge (it counts against the available physical/swap
memory available for the system).
The only issue is to actually check this change since side-effects are
really Linux specific and to actually account them it would require a
kernel specific tests to parse the system wide information. On the kernel
I checked /proc/self/statm does not show any meaningful difference for
vmm and/or rss before and after thread creation. I could only see
really meaningful information checking on system wide /proc/meminfo
between thread creation: MemFree, MemAvailable, and Committed_AS shows
large difference without the patch. I think trying to use these
kind of information on a testcase is fragile.
The BZ#18988 reports shows that the commit pages are easily seen with
mlockall (MCL_FUTURE) (with lock all pages that become mapped in the
process) however a more straighfoward testcase shows that pthread_create
could be faster using this patch:
--
static const int inner_count = 256;
static const int outer_count = 128;
static
void *thread1(void *arg)
{
return NULL;
}
static
void *sleeper(void *arg)
{
pthread_t ts[inner_count];
for (int i = 0; i < inner_count; i++)
pthread_create (&ts[i], &a, thread1, NULL);
for (int i = 0; i < inner_count; i++)
pthread_join (ts[i], NULL);
return NULL;
}
int main(void)
{
pthread_attr_init(&a);
pthread_attr_setguardsize(&a, 1<<20);
pthread_attr_setstacksize(&a, 1134592);
pthread_t ts[outer_count];
for (int i = 0; i < outer_count; i++)
pthread_create(&ts[i], &a, sleeper, NULL);
for (int i = 0; i < outer_count; i++)
pthread_join(ts[i], NULL);
assert(r == 0);

On x86_64 (4.4.0-45-generic, gcc 5.4.0) running the small benchtests
I see:
$ time ./test

sys 0m11.836s
While with the patch I see:
$ time ./test
real 0m0.696s
user 0m0.040s
sys 0m1.152s
So I added a pthread_create benchtest (thread_create) which check
the thread creation latency. As for the simple benchtests, I saw
improvements in thread creation on all architectures I tested the

x86-64: Implement memmove family IFUNC selectors in C
Implement memmove family IFUNC selectors in C.
All internal calls within libc.so can use IFUNC on x86-64 since unlike
x86, x86-64 supports PC-relative addressing to access the GOT entry so
that it can call via PLT without using an extra register. For libc.a,
we can't use IFUNC for functions which are called before IFUNC has been
initialized. Use IFUNC internally reduces the icache footprint since
libc.so and other codes in the process use the same implementations.
This patch uses IFUNC for memmove family functions within libc.

i686: Add missing IS_IN (libc) guards to vectorized strcspn
Since commit d957c4d3fa48d685ff2726c605c988127ef99395 (i386: Compile
rtld-*.os with -mno-sse -mno-mmx -mfpmath=387), vector intrinsics can
no longer be used in ld.so, even if the compiled code never makes it
into the final ld.so link. This commit adds the missing IS_IN (libc)
guard to the SSE 4.2 strcspn implementation, so that it can be used from
ld.so in the future.

Remove __need macros from errno.h (__need_Emath, __need_error_t).
This is fairly complicated, not because the users of __need_Emath and
__need_error_t have complicated requirements, but because the core
changes had a lot of fallout.
__need_error_t exists for gnulib compatibility in argz.h and argp.h.
error_t itself is a Hurdism, an enum containing all the E-constants,
so you can do 'p (error_t) errno' in gdb and get a symbolic value.
argz.h and argp.h use it for function return values, and they want to
fall back to 'int' when that's not available. There is no reason why
these nonstandard headers cannot just go ahead and include all of
errno.h; so we do that.
__need_Emath is defined only by .S files; what they _really_ need is
for errno.h to avoid declaring anything other than the E-constants
(e.g. 'extern int __errno_location(void);' is a syntax error in
assembly language). This is replaced with a check for __ASSEMBLER__ in
errno.h, plus a carefully documented requirement for bits/errno.h not
to define anything other than macros. That in turn has the
consequence that bits/errno.h must not define errno - fortunately, all
live ports use the same definition of errno, so I've moved it to
errno.h. The Hurd bits/errno.h must also take care not to define
error_t when __ASSEMBLER__ is defined, which involves repeating all of
the definitions twice, but it's a generated file so that's okay.
* stdlib/errno.h: Remove __need_Emath and __need_error_t logic.
Reorganize file. Declare errno here. When __ASSEMBLER__ is
defined, don't declare anything other than the E-constants.
* include/errno.h: Change conditional for exposing internal
declarations to (not _ISOMAC and not __ASSEMBLER__).
* bits/errno.h: Remove logic for __need_Emath. Document
requirements for a port-specific bits/errno.h.
* sysdeps/unix/sysv/linux/bits/errno.h
* sysdeps/unix/sysv/linux/alpha/bits/errno.h
* sysdeps/unix/sysv/linux/hppa/bits/errno.h
* sysdeps/unix/sysv/linux/mips/bits/errno.h
* sysdeps/unix/sysv/linux/sparc/bits/errno.h:
Add multiple-include guard and check against improper inclusion.
Remove __need_Emath logic. Don't declare errno here. Ensure all
constants are defined as simple integer literals. Consistent
formatting.
* sysdeps/mach/hurd/errnos.awk: Likewise. Only define error_t and
enum __error_t_codes if __ASSEMBLER__ is not defined.
* sysdeps/mach/hurd/bits/errno.h: Regenerate.
* argp/argp.h, string/argz.h: Don't define __need_error_t before
including errno.h.

Remove __need_IOV_MAX and __need_FOPEN_MAX.
__need_FOPEN_MAX wasn't being used anywhere. __need_IOV_MAX was more
complicated; the basic deal is that sys/uio.h wants to define a
constant named UIO_MAXIOV and bits/xopen_lim.h wants to define a
constant named IOV_MAX, with the same meaning. For no apparent reason
this was being handled via bits/stdio_lim.h -- stdio.h is NOT supposed
to define IOV_MAX -- and some mess in Makerules. Also, bits/uio.h on
Linux was being used as a dumping ground for extension functions.
So now we have bits/uio_lim.h, which defines __IOV_MAX.
bits/xopen_lim.h and sys/uio.h use that to define their respective
constants. We also now have bits/uio-ext.h, which is the official
Proper Home for extensions to sys/uio.h. bits/uio.h is removed, and
stdio_lim.h doesn't define IOV_MAX at all.
* bits/uio_lim.h, sysdeps/unix/sysv/linux/bits/uio_lim.h
* bits/uio-ext.h, sysdeps/unix/sysv/linux/bits/uio-ext.h: New file.
* bits/uio.h, sysdeps/unix/sysv/linux/bits/uio.h: Delete file.
* include/bits/xopen_lim.h: Use bits/uio_lim.h to get the value
for IOV_MAX.
* misc/Makefile: Install bits/uio-ext.h and bits/uio_lim.h.
Don't install bits/uio.h.
* misc/sys/uio.h: Don't include bits/uio.h. Do include
bits/types/struct_iovec.h and bits/uio_lim.h. Set UIO_MAXIOV
based on __IOV_MAX. Under __USE_GNU, also include bits/uio-ext.h.
* stdio-common/stdio_lim.h.in: Remove logic for __need_FOPEN_MAX
and __need_IOV_MAX. Don't define IOV_MAX at all.
* Makerules (stdio_lim.h): Remove logic for setting IOV_MAX.
* sysdeps/unix/sysv/linux/bits/fcntl-linux.h:
Include bits/types/struct_iovec.h, not bits/uio.h.
Use __ssize_t, not ssize_t, in function prototypes.
Don't use hard TAB for double space after period in comments.

PowerPC64 ELFv2 PPC64_OPT_LOCALENTRY
ELFv2 functions with localentry:0 are those with a single entry point,
ie. global entry == local entry, that have no requirement on r2 or
r12 and guarantee r2 is unchanged on return. Such an external
function can be called via the PLT without saving r2 or restoring it
on return, avoiding a common load-hit-store for small functions.
This patch implements the ld.so changes necessary for this
optimization. ld.so needs to check that an optimized plt call
sequence is in fact calling a function implemented with localentry:0,
end emit a fatal error otherwise.
The elf/testobj6.c change is to stop "error while loading shared
libraries: expected localentry:0 `preload'" when running
elf/preloadtest, which we'd get otherwise.

PowerPC64 sysdep.h tidy
.align on some targets takes a byte alignment, on others like powerpc,
log2 of the byte alignment. It's a good idea to avoid .align,
particularly since x86 and powerpc are different. This patch fixes
the occurrences of .align in powerpc64/sysdep.h, renames DOT_LABEL
since the macro doesn't have anything to do with adding dots, removes
extraneous semicolons, and fixes some formatting.

mips: Fix store/load gp registers to/from ucontext_t
General purpose registers in mcontext_t structure
are 8 bytes long for both MIPS32/MIPS64.
get/set/make/swap context implementations for MIPS O32
incorrectly assume that general purpose registers
in this structure are 4 bytes long.
This patch is fixing that.
Tested for MIPS O32 LE and BE.
Compared objdump of modified functions for mips n32 and mips n64.

Remove __need_schedparam and __cpu_set_t_defined.
bits/sched.h has logic to expose only an impl-namespace variant of
struct sched_param (i.e. struct __sched_param), but nothing uses it,
and the only header that includes bits/sched.h is sched.h. The
__need_schedparam logic can therefore be removed.
bits/sched.h also has a great deal of code relating to cpu_set_t
objects that was *almost* the same between the two versions of
bits/sched.h in the tree; a little spelunking indicated that this is
because some bug fixes got applied to the Linux-specific bits/sched.h
but not the generic one. Introduce a new header, bits/cpu-set.h,
containing the version of that code with the bugfixes, have sched.h
include it directly, and delete all of the code from both versions of
bits/sched.h.
Also remove the unnecessary name mangling in the definition of struct
sched_param -- POSIX specifies a field 'sched_priority', so there is
no reason to define it as '__sched_priority' and then paper over that
with a macro. (Just in case someone was using the internal name,
'sched_priority' remains a macro defined to expand to itself, and
'__sched_priority' now expands to 'sched_priority'.)
Finally, as long as I'm touching these files anyway, merge new
constants from linux/sched.h into the Linux bits/sched.h.
* bits/sched.h: Remove __need_schedparam logic and replace with a
normal multiple-include guard. Change field name in struct
sched_param from __sched_priority to sched_priority. Delete
everything under #ifndef __cpu_set_t_defined.
* sysdeps/unix/sysv/linux/bits/sched.h: Likewise. Also sync with
kernel sched.h, adding SCHED_ISO and SCHED_DEADLINE constants.
* posix/sched.h: Include bits/cpu-set.h as well as bits/sched.h.
For compatibility, #define sched_priority to itself, and #define
__sched_priority as sched_priority.
* posix/bits/cpu-set.h: New file containing, verbatim, the code
that was under #ifndef __cpu_set_t_defined in
sysdeps/unix/sysv/linux/bits/sched.h.
* include/bits/cpu-set.h: New wrapper.

Allow macros prefixed with FLT128 in include/float.h
TS 18661-3 specifies that macros prefixed with FLTN_ can be defined in
float.h, only if __STDC_WANT_IEC_60559_TYPES_EXT__ is defined as a macro
before the inclusion of float.h. Since GCC 7.0, these macros are provided
under this condition, however, for older versions of GCC, these macros are
not provided at all. This patch allows the definitions of such macros in
include/float.h for older compilers, if the condition above is met, and
even if _ISOMAC is defined.

Fix sigwait namespace (bug 21550).
sigwait was added to POSIX in 1995; it is not in older POSIX versions
or XPG4 / XPG4.2. Thus it should be declared only if
__USE_POSIX199506; signal.h wrongly declares it for __USE_POSIX.
(sigwaitinfo is correctly conditioned on __USE_POSIX199309.) This
patch fixes the condition on the declaration of sigwait.
Tested for x86_64. Because of other namespace problems this does not
allow any conform/ XFAILs to be removed.

x86-64: Implement strcpy family IFUNC selectors in C
Implement strcpy family IFUNC selectors in C.
All internal calls within libc.so can use IFUNC on x86-64 since unlike
x86, x86-64 supports PC-relative addressing to access the GOT entry so
that it can call via PLT without using an extra register. For libc.a,
we can't use IFUNC for functions which are called before IFUNC has been
initialized. Use IFUNC internally reduces the icache footprint since
libc.so and other codes in the process use the same implementations.
This patch uses IFUNC for strcpy family functions within libc.

powerpc: add sysconf support for cache geometries
There is currently no "cross-platform" (x86 and POWER) support for
determining the cacheline size.
This patch adds support to sysconf() to correctly report cacheline sizes
based on the information in the auxilliary vector.
Thus, using sysconf() is a cross-platform (x86 and POWER) solution for
determining cacheline sizes.
Support is added (on powerpc) for:
_SC_LEVEL1_ICACHE_SIZE _SC_LEVEL1_ICACHE_ASSOC _SC_LEVEL1_ICACHE_LINESIZE
_SC_LEVEL1_DCACHE_SIZE _SC_LEVEL1_DCACHE_ASSOC _SC_LEVEL1_DCACHE_LINESIZE
_SC_LEVEL2_CACHE_SIZE _SC_LEVEL2_CACHE_ASSOC _SC_LEVEL2_CACHE_LINESIZE
_SC_LEVEL3_CACHE_SIZE _SC_LEVEL3_CACHE_ASSOC _SC_LEVEL3_CACHE_LINESIZE
* sysdeps/unix/sysv/linux/powerpc/sysconf.c: New file.
Add powerpc-specific overrides for L1, L2, L3 CACHE_SIZEs,
CACHE_ASSOCs, and CACHE_LINESIZEs, retrieving from auxv.

and report results. If none are supported, report so.
* sysdeps/unix/sysv/linux/powerpc/Makefile (tests): Add new test,

Fix waitid namespace (bug 21561).
In sys/wait.h, waitid and associated constants and types are UX-shaded
in XPG4.2 (so not in XPG4), and XSI-shaded in POSIX before 2008, so
should be appropriately conditional in the headers. This patch fixes
the conditionals accordingly. (WCONTINUED is actually still
XSI-shaded in POSIX.1:2008, but W* is also reserved there without
XSI-shading, so nothing special needs to be done about the
conditionals on WCONTINUED to conform to POSIX.1:2008 namespace
rules.)

Update nios2, sparc32 localplt.data files for recent GCC change.
A recent GCC change to expand floating-point classification built-in
functions inline using integer rather than floating-point arithmetic
in some cases resulted in localplt test failures for nios2 and sparc32

This patch updates the localplt.data files in question to mark the

Fix sigpause namespace (bug 21554).
The sigpause function is declared for __USE_XOPEN. As it's new in
XPG4.2 it should be declared only for __USE_XOPEN_EXTENDED. This
patch fixes the declaration accordingly.
Tested for x86_64.

Condition signal.h inclusion in sys/wait.h (bug 21560).
sys/wait.h includes signal.h unconditionally. But the permission to
do so is UX-shaded in XPG4.2, and XSI-shaded in POSIX before 2008, so
this should not be unconditional. This patch fixes this
conservatively: the include is kept, but conditioned on the standards
that permit it (meaning it is still present by default, because
non-XSI POSIX.1:2008 is enabled by default). <bits/types.h> is now
included unconditionally to provide the required definition of
__pid_t; it was previously included via <signal.h>. Some standards
require pid_t to be defined here, and all allow it to be defined here;
previously defined via <signal.h>, it's now defined directly in this
header.
Tested for x86_64. This does not fix any of the sys/wait.h
conformtest failures, but substantially reduces the number of
namespace failures for sys/wait.h for XPG4 and POSIX.

Polish the treatment of dl-tunable-list.h in Makeconfig.
Like basically all before-compile headers, dl-tunable-list.h should be
generated using a stamp file to minimize unnecessary rebuilding; it
wasn't being added to common-generated, so it wouldn't get cleaned up;
and it was in between the rules for libc-modules.h/.stmp and their own
addition to common-generated.
* Makeconfig (dl-tunable-list.h): Generate using a stamp file.
(common-generated): Add libc-modules.h and libc-modules.stmp in a
more appropriate location. Also add dl-tunable-list.h and
dl-tunable-list.stmp.

conformtest: Correct sys/wait.h expectations for XPG4.
This patch corrects the conformtest expectations for sys/wait.h for
XPG4. This does not change the test results for this header at the
makefile level since it fixes some spurious failures for this header
while introducing other failures previously hidden by incorrect
expectations. However, it shows up issues with stdlib.h for XPG4
defining W* names that are not permitted in this case (previously
wrongly allowed; the W* reservation is UX-shaded in XPG4.2 /
XSI-shaded in POSIX before 2008); that test is thus XFAILed.

Remove duplicated code from __printf_fp_l, __printf_fphex, and __printf_size
In __printf_fp_l, __printf_fphex, and __printf_size the blocks of code that
are
used to read a double or long double argument, check for special values and
convert to multiprecision are similar. When adding float128 support to
libc,
more code would be duplicated to deal with the extra type. This patch moves
the repetitive code to a macro which is now used by double and long double
and
will be used for float128 when support is added, thus avoiding more
duplication.
Tested for powerpc64le and s390x.

Fix include paths in include/bits/types/*.h.
Various include/bits/types/*.h files do
where the path specified is relative to the toplevel glibc source
directory.
That has the wrong number of ../ components to achieve the desired
effect; it actually searches relative to include/ for a file that does
not exist there, then goes on to search the #include <> paths
specified with -I, eventually finding the desired file via such a path
(e.g. sysdeps/nptl/) with the right number of directory components.
Before that it searches include/../.. because of the -Iinclude,
meaning that an appropriately named file outside the glibc source tree
can affect the build.
This patch changes all those files to do #include <path> without the
../../, as some such files already do.
Tested for x86_64.

Fix tst-timezone race (bug 14096).
I observed a failure of timezone/tst-timezone with the same symptoms
as reported in bug 14096.
I was unable to reproduce the failure on testing again. However, from
inspection, the cause is as follows. tst-timezone uses time zones
compiled from the northamerica file, but has no dependency on any such
zones, so with a parallel build it is possible that they do not get
compiled until after tst-timezone is run. This patch adds a
dependency on the compiled America/New_York zone (the one used as a
makefile target to cause such zones to be compiled, rather than one
which is actually used in that test) to fix the race.
Tested for x86_64.

Remove check for NULL buffer passed to `ptsname_r'
`ptsname_r' is declared in stdlib.h to only accept a `nonnull'
second argument and therefore GCC may choose to make optimizations
based on the assumption that this argument is NULL. This means
that potentially, GCC can optimize away the NULL check at some
point in the future. Since this is a programming interface, we
might as well remove the NULL check ourselves.
This also warrants a change to the `ptsname_r' manual page that
must be submitted to the corresponding mailing list.
In addition, remove the NULL buffer test in login/tst-ptsname.c.

Make LD_HWCAP_MASK usable for static binaries
The LD_HWCAP_MASK environment variable was ignored in static binaries,
which is inconsistent with the behaviour of dynamically linked
binaries. This seems to have been because of the inability of
ld_hwcap_mask being read early enough to influence anything but now
that it is in tunables, the mask is usable in static binaries as well.
This feature is important for aarch64, which relies on HWCAP_CPUID
being masked out to disable multiarch. A sanity test on x86_64 shows
that there are no failures. Likewise for aarch64.

aarch64: Allow overriding HWCAP_CPUID feature check using HWCAP_MASK
Now that LD_HWCAP_MASK (or glibc.tune.hwcap_mask) is read early enough
to influence cpu feature check in aarch64, use it to influence
multiarch selection. Setting LD_HWCAP_MASK such that it clears
HWCAP_CPUID will now disable multiarch for the binary.
HWCAP_CPUID is also now set in HWCAP_IMPORTANT so that it is set by
default. With this patch, this feature is only usable with
dyanmically linked binaries because LD_HWCAP_MASK is not read for
static binaries. A future patch fixes that.

tunables: Clean up hooks to get and set tunables
The TUNABLE_SET_VALUE and family of macros (and my later attempt to
add a TUNABLE_GET) never quite went together very well because the
overall interface was not clearly defined. This patch is an attempt
to do just that.
This patch consolidates the API to two simple sets of macros,
TUNABLE_GET* and TUNABLE_SET*. If TUNABLE_NAMESPACE is defined,
TUNABLE_GET takes just the tunable name, type and a (optionally NULL)
callback function to get the value of the tunable. The callback
function, if non-NULL, is called if the tunable was externally set
(i.e. via GLIBC_TUNABLES or any future mechanism). For example:
val = TUNABLE_GET (check, int32_t, check_callback)
returns the value of the glibc.malloc.check tunable (assuming
TUNABLE_NAMESPACE is set to malloc) as an int32_t into VAL after
calling check_callback.
Likewise, TUNABLE_SET can be used to set the value of the tunable,
although this is currently possible only in the dynamic linker before
it relocates itself. For example:
TUNABLE_SET (check, int32_t, 2)
will set glibc.malloc.check to 2. Of course, this is not possible
since we set (or read) glibc.malloc.check long after it is relocated.
To access or set a tunable outside of TUNABLE_NAMESPACE, use the
TUNABLE_GET_FULL and TUNABLE_SET_FULL macros, which have the following
prototype:
TUNABLE_GET_FULL (glibc, tune, hwcap_mask, uint64_t, NULL)
TUNABLE_SET_FULL (glibc, tune, hwcap_mask, uint64_t, 0xffff)
In future the tunable list may get split into mutable and immutable
tunables where mutable tunables can be modified by the library and
userspace after relocation as well and TUNABLE_SET will be more useful
than it currently is. However whenever we actually do that split, we
will have to ensure that the mutable tunables are protected with
locks.

Optimize generic spinlock code and use C11 like atomic macros.
This patch optimizes the generic spinlock code.
The type pthread_spinlock_t is a typedef to volatile int on all archs.
Passing a volatile pointer to the atomic macros which are not mapped to the
C11 atomic builtins can lead to extra stores and loads to stack if such
a macro creates a temporary variable by using "__typeof (*(mem)) tmp;".
Thus, those macros which are used by spinlock code -
atomic_exchange_acquire,
atomic_load_relaxed, atomic_compare_exchange_weak - have to be adjusted.
According to the comment from Szabolcs Nagy, the type of a cast expression
is
unqualified (see
http://www.open-std.org/jtc1/sc22/wg14/www/docs/dr_423.htm):
__typeof ((__typeof (*(mem)) *(mem)) tmp;
Thus from spinlock perspective the variable tmp is of type int instead of
type volatile int. This patch adjusts those macros in include/atomic.h.
With this construct GCC >= 5 omits the extra stores and loads.
The atomic macros are replaced by the C11 like atomic macros and thus
the code is aligned to it. The pthread_spin_unlock implementation is now
using release memory order instead of sequentially consistent memory order.
The issue with passed volatile int pointers applies to the C11 like atomic
macros as well as the ones used before.
I've added a glibc_likely hint to the first atomic exchange in
pthread_spin_lock in order to return immediately to the caller if the lock
is
free. Without the hint, there is an additional jump if the lock is free.
I've added the atomic_spin_nop macro within the loop of plain reads.
The plain reads are also realized by C11 like atomic_load_relaxed macro.
The new define ATOMIC_EXCHANGE_USES_CAS determines if the first try to
acquire
the spinlock in pthread_spin_lock or pthread_spin_trylock is an exchange
or a CAS. This is defined in atomic-machine.h for all architectures.
The define SPIN_LOCK_READS_BETWEEN_CMPXCHG is now removed.
There is no technical reason for throwing in a CAS every now and then,
and so far we have no evidence that it can improve performance.
If that would be the case, we have to adjust other spin-waiting loops
elsewhere, too! Using a CAS loop without plain reads is not a good idea
on many targets and wasn't used by one. Thus there is now no option to
do so.
Architectures are now using the generic spinlock automatically if they
do not provide an own implementation. Thus the pthread_spin_lock.c files
in sysdeps folder are deleted.

x86-64: Optimize memcmp/wmemcmp with AVX2 and MOVBE
Optimize x86-64 memcmp/wmemcmp with AVX2. It uses vector compare as
much as possible. It is as fast as SSE4 memcmp for size <= 16 bytes
and up to 2X faster for size > 16 bytes on Haswell and Skylake. Select
AVX2 memcmp/wmemcmp on AVX2 machines where vzeroupper is preferred and
AVX unaligned load is fast.
NB: It uses TZCNT instead of BSF since TZCNT produces the same result
as BSF for non-zero input. TZCNT is faster than BSF and is executed
as BSF if machine doesn't support TZCNT.
Key features:
1. For size from 2 to 7 bytes, load as big endian with movbe and bswap
to avoid branches.
2. Use overlapping compare to avoid branch.
3. Use vector compare when size >= 4 bytes for memcmp or size >= 8
bytes for wmemcmp.
4. If size is 8 * VEC_SIZE or less, unroll the loop.
5. Compare 4 * VEC_SIZE at a time with the aligned first memory area.
6. Use 2 vector compares when size is 2 * VEC_SIZE or less.
7. Use 4 vector compares when size is 4 * VEC_SIZE or less.
8. Use 8 vector compares when size is 8 * VEC_SIZE or less.

x86-64: Optimize wmemset with SSE2/AVX2/AVX512
The difference between memset and wmemset is byte vs int. Add stubs
to SSE2/AVX2/AVX512 memset for wmemset with updated constant and size:
SSE2 wmemset:
shl $0x2,%rdx
movd %esi,%xmm0
mov %rdi,%rax
pshufd $0x0,%xmm0,%xmm0
jmp entry_from_wmemset

movd %esi,%xmm0
mov %rdi,%rax
punpcklbw %xmm0,%xmm0
punpcklwd %xmm0,%xmm0
pshufd $0x0,%xmm0,%xmm0
entry_from_wmemset:
Since the ERMS versions of wmemset requires "rep stosl" instead of
"rep stosb", only the vector store stubs of SSE2/AVX2/AVX512 wmemset
are added. The SSE2 wmemset is about 3X faster and the AVX2 wmemset

x86_64: Remove redundant REX bytes from memrchr.S
By x86-64 specification, 32-bit destination registers are zero-extended
to 64 bits. There is no need to use 64-bit registers when only the lower
32 bits are non-zero. Also 2 instructions in:
mov %rdi, %rcx
and $15, %rcx
jz L(length_less16_offset0)
mov %rdi, %rcx <<< redundant
and $15, %rcx <<< redundant
are redundant.

x86-64: Update LO_HI_LONG for p{readv,writev}{64}v2
The kernel interface for p{readv,writev}{64}v is
(unsigned long fd, {const }struct iovec *iov, unsigned long vlen,
unsigned long pos_l, unsigned long pos_h)
Except for targets which define __ARCH_WANT_COMPAT_SYS_PREADV64 and
__ARCH_WANT_COMPAT_SYS_PWRITEV64,
(unsigned long fd, {const }struct iovec *iov, unsigned long vlen,
off64_t pos)
is used for p{readv,writev}{64}v. X32 is the only such target. The
LO_HI_LONG macro is used to pass offset to the pos_l and pos_h pair.
Since pos_h is ignored when size of offset == sizeof of pos_l, x86-64
has
#define LO_HI_LONG(val) (val)
But the kernel interface for p{readv,writev}{64}v2 is
(unsigned long fd, {const }struct iovec *iov, unsigned long vlen,
unsigned long pos_l, unsigned long pos_h, int flags)
Except for targets which define __ARCH_WANT_COMPAT_SYS_PREADV64V2 and
__ARCH_WANT_COMPAT_SYS_PWRITEV64V2,
(unsigned long fd, {const }struct iovec *iov, unsigned long vlen,
off64_t pos, int flags)
is used for p{readv,writev}{64}v2. X32 is the only such target. Update
x86-64 LO_HI_LONG to pass 0 as the high part of the offset argument for
p{readv,writev}{64}v2 and define a different LO_HI_LONG for x32 to only
pass one argument for offset.
Tested on x32 and x86-64.
* sysdeps/unix/sysv/linux/x86_64/sysdep.h (LO_HI_LONG): Pass
0 as the high part of offset.

Define SIG_HOLD for XPG4 (bug 21538).
Various bits/signum.h headers define SIG_HOLD if __USE_UNIX98. That
should be __USE_XOPEN, as this macro is in XPG4. This patch fixes the
conditionals accordingly. Because of other header bugs, this does not
allow any XFAILs to be removed (however, the XPG4/signal.h/conform
XFAIL only depends on a few such straightforward header bugs, not on
the more complicated to fix ucontext_t issues, as ucontext_t isn't
included in signal.h in XPG4).
Tested for x86_64.

Fix struct sigaltstack namespace (bug 21517).
glibc defines the stack_t type with the tag struct sigaltstack. This
is not permitted by POSIX; sigaltstack is only reserved with file
scope in the namespace of ordinary identifiers, not the tag namespace,
and in the case where stack_t is obtained from ucontext.h rather than
signal.h, it's not reserved with file scope at all.
This patch removes the tag accordingly and updates uses in glibc of
struct sigaltstack. This is similar to the removal of the "struct
siginfo" tag a few years ago: C++ name mangling changes are an
unavoidable consequence. A NEWS item is added to note the changed
mangling. There is inevitably some risk of breaking builds of
anything that relies on the struct sigaltstack name (though the first
few hits I looked at from codesearch.debian.net generally seemed to
involve code that could use the stack_t name conditionally, so
depending on how they determine the conditionals they may work with
glibc not defining the struct tag anyway).
Tested for x86_64 and x86, and with build-many-glibcs.py.

Include shlib-compat.h in many sunrpc/nis source files.
Every file that uses libc_hidden_nolink_sunrpc or
libnsl_hidden_nolink_def needs to include shlib-compat.h. Currently,
most of them are getting it via stdio.h, because libio.h refers to
SHLIB_COMPAT when _LIBC is defined, so it includes shlib-compat.h. My
experimental patch to not install libio.h breaks that chain; stdio.h
no longer pulls in libio.h even for internal users.
Accordingly, this patch adds #include <shlib-compat.h> to many files
in sunrpc/ and nis/. There are also a small number of really obvious
fixups to includes that caught my eye while proofreading the patch -
not including headers twice in a row, not worrying about portability
to Ultrix anymore, sort of thing.

__x86_shared_non_temporal_threshold was set to 6 times of per-core
shared cache size, based on the large memcpy micro benchmark in glibc
on a 8-core processor. For a processor with more than 8 cores, the
threshold is too low. Set __x86_shared_non_temporal_threshold to the
3/4 of the total shared cache size so that it is unchanged on 8-core
processors. On processors with less than 8 cores, the threshold is
lower.

Fix sigevent namespace (bug 21543).
signal.h defines the sigevent structure and constants if defined
__USE_POSIX199309 || defined __USE_XOPEN_EXTENDED. The
__USE_XOPEN_EXTENDED condition is incorrect; this structure does not
appear in XSI standards before Unix98 (which implies
__USE_POSIX199309). This patch fixes the conditionals accordingly
(the existing conditional is correct for siginfo_t, just not for
sigevent).
Tested for x86_64. This does not allow any conform/ XFAILs to be
removed because of other signal.h namespace bugs.

Various of the signal.h conform/ failures for XPG4 and XPG42 are
actually the result of incorrect test expectations rather than header
bugs. This patch fixes the expectations to accord with those
standards (this does not however allow any XFAILs to be removed, as
some header bugs remain). Note for anyone comparing with the
standards: corrigendum U013/16 removes the mention of a sigmask
function in signal.h (C435 lists such a function in the definition of
signal.h, but without any actual specification for the function
itself), so sigmask is not included in the expectations.

Add shim header for bits/syscall.h.
On Linux-based configurations, bits/syscall.h is a generated file.
To avoid build-ordering problems, the Linux sys/syscall.h only includes
bits/syscall.h if _LIBC is not defined. After the _ISOMAC-testsuite
changes, this means any test case that includes sys/syscall.h tries to
pull in bits/syscall.h. This would be fine, because it'll definitely
have been generated by the time we start compiling tests, except that
the generated <builddir>/misc/bits/syscall.h is not visible in the
include path, because nothing needed it till now. So we either get
the bits/syscall.h from the host system, or the build fails.
The fix is simple: add a shim header for bits/syscall.h. I put it in
sysdeps/unix/sysv/linux/include instead of the top-level include/
because bits/syscall.h doesn't exist at all on other configurations as
far as I can tell.
This is known to affect nptl/tst-cond2[45]. Thanks to John David
Anglin for noticing the problem.

Fix more namespace issues in sys/ucontext.h (bug 21457).
Continuing the fixes for namespace issues in sys/ucontext.h, this
patch moves various symbols into the implementation namespace in the
absence of __USE_MISC. As with previous changes, it is nonexhaustive,
just covering more straightforward cases.
Structure fields are generally changed to have a prefix __ in the
absence of __USE_MISC, via a macro __ctx (used without a space before
the open parenthesis, since the result is a single identifier).
Various macros such as NGREG also have leading __ added. No changes
are made to structure tags (and thus to C++ name mangling), except
that in the (unused) file sysdeps/i386/sys/ucontext.h, structures
defined inside other structures as the type for a field have their
tags removed in the non-__USE_MISC case (those structure tags would
not in any case have been visible in C++, because in C++ the scope of
such a tag is limited to the containing structure). No changes are
made to the contents of bits/sigcontext.h, or to whether it is
included. Because of remaining namespace issues, this patch does not
yet fix the bug or allow any XFAILs to be removed.
Tested for x86_64 and x86, and with build-many-glibcs.py.

Avoid tickling a linker bug from microblaze pt-vfork.S.
libpthread used to have its own vfork implementation that differed
from libc's only in having a pointless micro-optimization. There is
no longer any use to having a separate copy in libpthread, but the
historical ABI requires a compatibility shim. microblaze was trying
to be slightly too clever about how it did this, and tickled a linker
bug. The linker bug should get fixed eventually, but there's no
reason for us to keep tickling it in the meantime.
This doesn't reuse the generic pt-vfork.c because microblaze doesn't
have IFUNC support yet, and it doesn't reuse aarch64/pt-vfork.c
because that fails to generate a tailcall (with GCC 7.1.1).
* sysdeps/unix/sysv/linux/microblaze/pt-vfork.S: Don't include
alpha/pt-vfork.S. Provide own compat shim for vfork and __vfork.
* sysdeps/unix/sysv/linux/microblaze/vfork.S: Add __libc_vfork alias.
* sysdeps/unix/sysv/linux/microblaze/localplt.data:
libpthread.so no longer references __errno_location.

posix: Implement preadv2 and pwritev2
This patch adds support of preadv2 and pwritev2 which are similar to
preadv/pwritev but with an extra flag argument. As for preadv/pwritev
both interfaces are added a non-standard GNU API.
For default 'posix' implementation trying to emulate the Linux supported
flags is troublesome:
* We can not temporary change the file state of the O_DSYNC and O_SYNC
flags to emulate RWF_{D}SYNC (attempts to change the state of using
fcntl are silently ignored).
* IOCB_HIPRI requires the file opened in O_DIRECT and uses an internal
semantic not provided by any other flag (O_NONBLOCK for instance).
So default sysdeps/posix implementations fails with EOPNOTSUPP for any non
supported flag (which are none currently) calls generic preadv/pwritev.
Basically this implementation supports only preadv2 called as preadv (with
flags sets to 0).
The Linux one uses the preadv2/pwritev2 syscall if defined, otherwise it
call preadv/writev. Instead of using the previous __ASSUME_* to
unconditionally issue the syscall (and avoid building the fallback routine),
it call pread/write if the preadv2/pwritev2 syscalls fails. The idea
is just avoid adding another __ASSUME_* and checking each architecture
on every kernel bump and simplify code conditionals.

Delay initialization of CPU features struct in static binaries
Allow the CPU features structure set up to be overridden by tunables
by delaying it to until after tunables are initialized. The
initialization is already delayed in dynamically linked glibc, it is
only in static binaries that the initialization is set early to allow
it to influence IFUNC relocations that happen in libc-start. It is a
bit too early however and there is a good place between tunables
initialization and IFUNC relocations where this can be done.
Verified that this does not regress the testsuite.

Add reallocarray function
The reallocarray function is an extension from OpenBSD. It is an
integer-overflow-safe replacement for realloc(p, X*Y) and
malloc(X*Y) (realloc(NULL, X*Y)). It can therefore help in preventing
certain security issues in code.
This is an updated version of a patch originally submitted by Rüdiger
Sonderfeld in May 2014 [1].

Fix sigstack namespace (bug 21511).
The sigstack function was removed in the 2001 edition of POSIX, and
the sigstack structure in the 2008 edition. signal.h wrongly includes
those declarations even for newer POSIX versions. This patch fixes
the conditions, and conform/ expectations, accordingly.
This patch makes the minimum change to when these declarations are
present, leaving them visible for __USE_MISC as they would previously
have been visible by default. Arguably these legacy declarations
should only be visible when an old standard is specifically requested,
but implementing that would require arranging for the various sigstack
implementations to be able to see the struct sigstack type despite it
not being in _GNU_SOURCE in that case.
Tested for x86_64.

* signal/signal.h: Include <bits/types/struct_sigstack.h> only if
[(__USE_XOPEN_EXTENDED && !__USE_XOPEN2K8) || __USE_MISC].

Fix sys/ucontext.h namespace from signal.h etc. inclusion (bug 21457).
The various sys/ucontext.h headers include <signal.h> and all the
headers split out of <bits/sigstack.h>. (Except that the powerpc
version does not include <signal.h>.)
None of the standard versions defining ucontext.h require or permit
such inclusions; rather, they all say that the stack_t and sigset_t
types from signal.h are defined. This patch fixes the headers to
include just the bits/ headers for those types (and the existing
includes of bits/sigcontext.h). Since bits/types/sigset_t.h is now
being included instead of bits/types/__sigset_t.h, __sigset_t uses in
the headers are replaced by direct use of the public sigset_t type.
sysdeps/unix/sysv/linux/x86/bits/sigcontext.h was relying on the prior
inclusion of <signal.h> to define types such as __uint32_t, so gets a
bits/types.h include added to provide those types.
Although one could keep some or all of the includes under a __USE_MISC
conditional, that seems unnecessary to me, especially given the lack
of a <signal.h> include in the powerpc version meaning that portable
programs already cannot rely on such an include.
Tested for x86_64 and x86, and with build-many-glibcs.py. As with
other such fixes, more namespace issues remain so this does not permit
any XFAILs to be removed or bugs to be closed.

libio: Avoid dup already opened file descriptor [BZ#21393]
As described in BZ#21398 (close as dup of 21393) report current
freopen implementation fails when one tries to freopen STDIN_FILENO,
STDOUT_FILENO, or STDERR_FILENO. Although on bug report the
discussion leads to argue if a close followed by a freopen on the
standard file is a valid operation, the underlying issue is not
really the check for dup3 returned value, but rather calling it
if the returned file descriptor is equal as the input one.
So for a quality of implementation this patch avoid calling dup3
for the aforementioned case. It also adds a dup3 error case check
for the two possible failures, with one being Linux only: EINTR and
EBUSY. The EBUSY issue is better explained on this stackoverflow
thread [1], but in a short it is due the internal Linux
implementation which allows a race condition window for dup2 due
the logic dissociation of file descriptor allocation and actual
VFS 'install' operation. For both outliers failures all allocated
memory is freed and a NULL FILE* is returned.
With this patch the example on BZ#21398 is now actually possible
(I used as the testcase for the bug report). Checked on
x86_64-linux-gnu.
[BZ #21393]
* libio/freopen.c (freopen): Avoid dup already opened file descriptor
and add a check for dup3 failure.
* libio/freopen64.c (freopen64): Likewise.
* libio/tst-freopen.c (do_test): Rename to do_test_basic and use
libsupport.
(do_test_bz21398): New test.

Remove useless comment from sysdeps/sparc/sparc32/dl-machine.h
David Miller has not been shot yet AFAIK (yes, I googled for any news
that may seem relevant and I poked him on twitter some days ago) so
either nobody uses SPARC or the code is correct or nobody read the
instructions in the comment to shoot him. In all of those cases the
comment is clearly not useful, so getting rid of it.

* signal/Makefile (headers): Add bits/types/sigval_t.h.

Author: Zack Weinberg <address@hidden>

Remove __need macros from signal.h.
The types affected are __sig_atomic_t, sig_atomic_t, __sigset_t,
sigset_t, sigval_t, sigevent_t, and siginfo_t. __sig_atomic_t is a
scalar, so it's now directly available from bits/types.h. The others
get bits/types/ headers.
Side effects include: There have been small changes to which
non-signal headers expose which subset of the signal-related types.
A couple of architectures' nested siginfo_t fields had to be renamed
to prevent undesired macro expansion. Internal code that wants to
manipulate signal masks must now include <sigsetops.h> (which is not
installed) and should be aware that __sigaddset, __sigandset,
__sigdelset, __sigemptyset, and __sigorset no longer return a value
(unlike the public API). Relatedly, the public signal.h no longer
declares any of those functions. The obsolete sigmask() macro no
longer has a system-specific definition -- in the cases where it
matters, it didn't work anyway.
New Linux architectures should create bits/siginfo-arch.h and/or
bits/siginfo-consts-arch.h to customize their siginfo_t, rather than
duplicating everything in bits/siginfo.h (which no longer exists).
Add new __SI_* macros if necessary. Ports to other operating systems
are strongly encouraged to generalize this scheme further.

Remove __need_list_t and __need_res_state.
These __need macros are only used internally, by nptl/descr.h.
However, including all of resolv.h from descr.h causes build failures
due to resolv.h's dozens of pseudo-struct-field macros, some of which
collide with struct fields in NPTL internal data structures.
Similarly, including all of list.h from descr.h produces an include
cycle, atomic.h -> atomic-machine.h -> tls.h -> descr.h -> list.h ->
atomic.h, and then list.h tries to use atomic.h macros that haven't
been defined yet. So we do need mini-headers for these. In the
list.h case I called it include/list_t.h since it isn't going to be
installed.

Remove the bulk of the NaCl port.
The NaCl port has not been actively maintained since before the 2.25
release. The complementary GCC back-end was never contributed to GCC,
and we are given to understand that the current NaCl SDK has switched
to Clang and therefore cannot be used to build glibc anymore, so we
doubt that the port remains useful.
This commit simply removes the sysdeps/arm/nacl and sysdeps/nacl
directories and the abi-tags entry.

manual: Convert errno @comments to new @errno macro.
errno.texi documents error macros, their values, and error strings in
Texinfo @comments, some of which are also used for @standards. The
purpose of this commit is to separate the standards from the error
strings so that both the @standards conversion script picks up clean
@standards and the errno documentation framework is improved.
The error names, values, and messages are consolidated in a new custom
macro, @errno. It is not clear that scripts within the sources rely
on the special Texinfo @comment-based format to generate files used
throughout the library, so the definition of @errno in macros.texi now
provides a comment indicating the dependency. The dependent scripts
are updated to use @errno, which also simplifies them a bit. The
files those scripts generate were verified to be unchanged.
The @errno macro is not visibly rendered in any way at this time, but
it does use an @cindex command to add the error string to the Concept
Index, to facilitate searching on error messages.
* manual/errno.texi: Convert @comment-based errno
documentation to @errno.

their values, and messages, adding the error string to the

Split up bits/sigstack.h.
bits/sigstack.h contains four things: the legacy struct sigstack type,
the preferred stack_t type, the SS_* enum values and macros for signal
stack sizes.
These vary in different ways between glibc configurations; in
particular, the stack sizes vary much more than any of the other
pieces. Furthermore, these pieces have different standard namespace
rules for when they should be visible (not currently visible in
conform/ results both because the relevant tests are XFAILed for
sys/ucontext.h namespace issues, and because some of the expectations
are incorrect in the same way as the headers, e.g. neither
expectations nor headers reflect that current POSIX no longer has
either the sigstack function or the sigstack structure).
To reduce duplication of identical definitions, and facilitate
namespace fixes without requiring the same feature test macro
conditions to be repeated in many versions of the same header, this
patch splits bits/sigstack.h up into four headers. It keeps the stack
size macros, while new bits/types/struct_sigstack.h,
bits/types/stack_t.h and bits/ss_flags.h are added for the other
pieces. bits/types/struct_sigstack.h is the same everywhere,
bits/types/stack_t.h has three variants different in the order of the
structure elements (generic = MIPS Linux, and other Linux), and
bits/ss_flags.h has generic and Linux variants.
This patch includes the new headers everywhere that included
<bits/sigstack.h>, so should cause no difference to what any public
header defines. Subsequent namespace fixes would then remove or
condition some of those includes.
There should be no conflicts with Zack's changes to signal.h types,
beyond the trivial conflict of both making additions to
signal/Makefile's headers list; the two patches affect disjoint sets
of types and other definitions.

x86: Optimize SSE2 memchr overflow calculation
SSE2 memchr computes "edx + ecx - 16" where ecx is less than 16. Use
"edx - (16 - ecx)", instead of satured math, to avoid possible addition
overflow. This replaces
add %ecx, %edx
sbb %eax, %eax
or %eax, %edx
sub $16, %edx
with
neg %ecx
add $16, %ecx
sub %ecx, %edx
It is the same for x86_64, except for rcx/rdx, instead of ecx/edx.

Also create and use ldbl-compat-choose.h.
This patch makes the glibc build generate an additional header
ldbl-compat-choose.h that defines LONG_DOUBLE_COMPAT_CHOOSE_* macros
for each libc and libm symbol, which select one or the other of their
arguments based on whether the symbol was added before a change to
long double != double.
The effect of this is that it is then possible to define a macro
maybe_long_double_symbol that automatically acts as either
long_double_symbol or weak_alias depending on when the symbol being
defined was added. This can be used when building long double
functions from type-generic templates. Thus, with this patch ldbl-opt
no longer needs special long double implementations of each new libm
function added using such a template, and the existing such
implementations are removed.
This is a step towards being able more generally to use common macros
to create all the aliases needed for a libm function, so reducing the
amount of special-case code needed in ldbl-opt and ldbl-64-128, and
facilitating subsequently adding *f32 / *f64 / *f128 / *f32x / *f64x
aliases to existing functions (where the set of aliases that a
function should have may depend on the architecture in various ways).
Tested with build-many-glibcs.py. Except for on
powerpc64le-linux-gnu, installed stripped shared libraries are
unchanged by the patch. powerpc64le-linux-gnu is the unique
configuration which used ldbl-opt from the start rather than adding a
new long double choice after originally only having had long double =
double. The effect of the patch there is that various cases that
previously used long_double_symbol unconditionally now use weak_alias
instead, so .os files contain e.g. a symbol cabsl instead of
cabsl@@GLIBC_2.17. The final dynamic symbols and versions in the
resulting shared libraries are unchanged (ABI tests pass), as is the
disassembly of the shared libraries, but the differences in the .os
files still result in different .gnu_hash contents in libm.so; the
differences are of no significance and logically using weak_alias is
what's most appropriate in those cases.

Create and use first-versions.h with macros for function symbol versions.
This patch arranges for the glibc build to generate a header
first-versions.h that defines macros for the earliest symbol version
in which each public symbol (GLIBC_[0-9]* symbol version, name only
uses C identifier characters) is available.
This is used in sysdeps/ieee754/ldbl-opt/math-type-macros-double.h to
replace the manually defined LDOUBLE_*_libm_version macros for various
functions defined using type-generic templates, the purpose of which
is to use in LONG_DOUBLE_COMPAT tests "was this function originally
added before glibc supported long double != double on this platform?".
As discussed in
<https://sourceware.org/ml/libc-alpha/2016-12/msg00246.html>, I expect
this to be useful more generally in reducing the amount of
special-case code needed in ldbl-opt and ldbl-64-128.

libraries are unchanged by this patch.

This patch consolidates the pause Linux implementation on

(__NR_pause) will be used, other ppoll with 0 arguments will be

It has the small advantage of generic pause implementation with
uses rt_sigprocmask plus rt_sigsuspend because it requires only
one syscall and the pause is done atomically regarding signal
handling (for instance, pause may not be interrupted if the
signal arrives between the rt_sigprocmask and rt_sigsuspend
syscall).

Reduce value of LD_HWCAP_MASK for tst-env-setuid test case
It was discovered that the dynamic linker allocates a massive amount
of memory that increases with the value of LD_HWCAP_MASK. Due to
this, setting its value to 0xffffffff in the environment of
tst-env-setuid would cause it to fail in some environments where
overcommit was disabled or severely constrained because malloc would
fail.
Since this test is only concerned with the value of LD_HWCAP_MASK
envvar being conserved (or not, for setxid binaries), lower its value
to avoid spurious failures.
The allocation bug is reported as #21502.

manual: Convert @tables of annotated @items to @vtables.
The conversion script will convert these annotations, but the
replacement Summary-generation script won't catch them because @items
in @tables are not generally considered annotatable, causing them to
be skipped over (or cause errors). Using @vtable ensures their
continued presence in the Summary, with the added benefit that Texinfo
will also automatically include them in the Variable and Constant

Convert e_exp2l.c into a template
This patch converts the implementation of exp2l in math/e_exp2l.c into

this template for long double (the implementations for float and
double in sysdeps have higher precedence and are not used). This
template can also be used for float128, thus reducing the amount of
duplicated code that gets added when adding support the new type.

tunables: Add support for tunables of uint64_t type
Recognize the uint64_t type in addition to the current int32_t and
size_t. This allows addition of tunables of uint64_t types. In
addition to adding the uint64_t type, this patch also consolidates
validation and reading of integer types in tunables.
One notable change is that of overflow computation in
tunables_strtoul. The function was lifted from __internal_strtoul,
but it does not need the boundary condition check (i.e. result ==
ULONG_MAX) since it does not need to set errno. As a result the check
can be simplified, which I have now done.

posix: Fix and simplify default p{read,write}v implementation
Currently all architectures but microblaze use wire-up syscall for
p{readv,write}v. Microblaze still uses the syscall emulation using
sysdep/posix/p{readv,writev}.c and it was reported in some ocasions
[1] [2] that it might have some issues with some linux specific
usage (mainly with O_DIRECT and the alignment requirement).
Although it is not an issue for virtually all the system, this
patch refactors the sysdeps/posix p{read,write}v syscall to avoid
such issue (by using posix_memalign on the buffer used on
p{read,write} call) and by refactoring it common files to avoid
the need check on defines to correct set the alias and internal
symbols.
Checked on microblaze-linux-gnu check with run-built-tests=no and
by using the sysdeps/posix implementation on x86_64-linux-gnu (just
for sanity test where it shown no regression).

float128: Enable use of IEEE wrapper templates
The templates for the IEEE functions wrappers implement wrappers that
do not rely on _LIB_VERSION / matherr / __kernel_standard
functionality to set errno and fix the return value of the functions.
The wrappers are ready to be used by all floating-point types, however
they will first be used by float128, since the old wrappers for float,
double, and long double need to be first deprecated and versioned.
This commits defines __USE_WRAPPER_TEMPLATE to 1 for float128 files,
so that the new wrapper templates are used for this type.

Remove useless SPARC signbit aliases.
The SPARC implementations of __signbit* functions have aliases
signbit, signbitf, signbitl. These are useless, as they aren't
exported from the shared libraries (only the __signbit* functions are
exported, to be used by the type-generic signbit macro with older
compilers). This patch removes the useless aliases.

Suppress internal declarations for most of the testsuite.
This patch adds a new build module called 'testsuite'.
IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus
(which means several ad-hoc tests for __cplusplus can go away).
libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is
defined; in particular, _ISOMAC mode does not get config.h
automatically anymore.
There are still quite a few tests that need to see internal gunk of
one variety or another. For them, we now have 'tests-internal' and
'test-internal-extras'; files in this category will still be compiled
with MODULE_NAME=nonlib, and everything proceeds as it always has.
The bulk of this patch is moving tests from 'tests' to
'tests-internal'. There is also 'tests-static-internal', which has
the same effect on files in 'tests-static', and 'modules-names-tests',
which has the *inverse* effect on files in 'modules-names' (it's
inverted because most of the things in modules-names are *not* tests).
For both of these, the file must appear in *both* the new variable and
the old one.
There is also now a special case for when libc-symbols.h is included
without MODULE_NAME being defined at all. (This happens during the
creation of libc-modules.h, and also when preprocessing Versions
files.) When this happens, IS_IN is set to be always false and
_ISOMAC is *not* defined, which was the status quo, but now it's
explicit.
The remaining changes to C source files in this patch seemed likely to
cause problems in the absence of the main change. They should be
relatively self-explanatory. In a few cases I duplicated a definition
from an internal header rather than move the test to tests-internal;
this was a judgement call each time and I'm happy to change those
however reviewers feel is more appropriate.
* Makerules: New subdir configuration variables 'tests-internal'
and 'test-internal-extras'. Test files in these categories will
still be compiled with MODULE_NAME=nonlib. Test files in the
existing categories (tests, xtests, test-srcs, test-extras) are
now compiled with MODULE_NAME=testsuite.
New subdir configuration variable 'modules-names-tests'. Files
which are in both 'modules-names' and 'modules-names-tests' will
be compiled with MODULE_NAME=testsuite instead of
MODULE_NAME=extramodules.
(gen-as-const-headers): Move to tests-internal.
(do-tests-clean, common-mostlyclean): Support tests-internal.
* Makeconfig (built-modules): Add testsuite.
* Makefile: Change libof-check-installed-headers-c and
libof-check-installed-headers-cxx to 'testsuite'.
* Rules: Likewise. Support tests-internal.
* benchtests/strcoll-inputs/filelist#en_US.UTF-8:
Remove extra-modules.mk.
* config.h.in: Don't check for __OPTIMIZE__ or __FAST_MATH__ here.
* include/libc-symbols.h: Move definitions of _GNU_SOURCE,
PASTE_NAME, PASTE_NAME1, IN_MODULE, IS_IN, and IS_IN_LIB to the
very top of the file and rationalize their order.
If MODULE_NAME is not defined at all, define IS_IN to always be
false, and don't define _ISOMAC.
If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are
true, define _ISOMAC and suppress everything else in this file,
starting with the inclusion of config.h.
Do check for inappropriate definitions of __OPTIMIZE__ and
__FAST_MATH__ here, but only if _ISOMAC is not defined.
Correct some out-of-date commentary.
* include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE
and _Mlong_double_ before including math.h.
* include/string.h: If _ISOMAC is defined, don't expose

* string/test-strstr.c: Provide dummy definition of
libc_hidden_builtin_def when including strstr.c.

Remove _IO_MTSAFE_IO from public headers.
_IO_MTSAFE_IO controls whether stdio is *built* with support for
multithreading. In the distant past it might also have worked as a
feature selection macro, allowing library *users* to select
thread-safe or lock-free stdio at application build time, I haven't
done the archaeology. Nowadays, defining _IO_MTSAFE_IO while using
the installed headers, or in _ISOMAC mode, will cause libio.h to throw
syntax errors.
This patch removes _IO_MTSAFE_IO from the public headers
(specifically, from libio/libio.h). The most important thing it
controlled in there was whether libio.h defines _IO_lock_t itself or
expects stdio-lock.h to have done it, and we do still need a
inter-header communication macro for that, because stdio-lock.h can
only define _IO_lock_t as a typedef. I've invented
_IO_lock_t_defined, which is defined by both versions of stdio-lock.h.
_IO_MTSAFE_IO also controlled the definitions of a handful of macros
that _might_ count as part of the public libio.h interface. They are
now unconditionally given their non-_IO_MTSAFE_IO definition in
libio/libio.h, and include/libio.h redefines them with the
_IO_MTSAFE_IO definition. This should minimize the odds of breaking
old software that actually uses those macros.
I suspect that this entire mechanism is vestigial, and that glibc
won't build anymore if you *don't* define _IO_MTSAFE_IO, but that's
another patchset. The bulk of libio.h is internal-use-only stuff that
no longer makes sense to expose (libstdc++ gave up on making a FILE
the same object as a C++ filebuf *decades* ago) but that, too, is
another patchset.
* libio/libio.h: Condition dummy definition of _IO_lock_t on
_IO_lock_t_defined, not _IO_MTSAFE_IO. Unconditionally use the
non-_IO_MTSAFE_IO definitions for _IO_peekc, _IO_flockfile,
_IO_funlockfile, and _IO_ftrylockfile. Only define
_IO_cleanup_region_start and _IO_cleanup_region_end if not
already defined.
* include/libio.h: If _IO_MTSAFE_IO is defined, redefine
_IO_peekc, _IO_flockfile, _IO_funlockfile, and _IO_ftrylockfile
appropriately.
* sysdeps/generic/stdio-lock.h, sysdeps/nptl/stdio-lock.h:
Define _IO_lock_t_defined after defining _IO_lock_t.

powerpc: Fix signal handling in backtrace
Now with read consolidation which uses SYSCALL_CANCEL macro, a frame
pointer is created in the syscall code and this makes the powerpc
backtrace obtain a bogus entry for the signal handling patch.
It is because it does not setup the correct frame pointer register
(r1) based on the saved value from the kernel sigreturn. It was not
failing because the syscall frame pointer register was the same one
for the next frame (the function that actually called the syscall).
This patch fixes it by setup the next stack frame using the saved
one by the kernel sigreturn. It fixes tst-backtrace{5,6} from
the read consolidation patch.

tunables: Make tunable_list relro
As of now we don't need tunables to be writable after they have been
set initially, so there is no point in having them writable. Put
tunable_list in .data.rel.ro so that it is set as read-only after
relocation. This also allows us to move some of the dl_* variables
that are tunables controlled into the tunables infrastructure instead
of having two copies.
In future if we ever need specific tunables to be writable at runtime,
we can split the tunable_list into two.
Regression tested on x86_64 to verify that tests continue to pass.
* scripts/gen-tunables.awk: Add attribute_relro to
tunable_list.

Condition some sys/ucontext.h contents on __USE_MISC (bug 21457).
Continuing the fixes for namespace issues arising from sys/ucontext.h,
this patch conditions various definitions, that are not needed for
defining mcontext_t / ucontext_t, on __USE_MISC, so they do not appear
in strict POSIX modes.
This patch is non-exhaustive; that is, it only conditions
straightforward cases and there may be more such definitions that can
be conditioned for these and other architectures, to be dealt with
later in separate patches. Also, using __USE_MISC is the minimum
change for these definitions where they conflict with POSIX; some
headers already have __USE_GNU conditionals on similar definitions of
names for registers. The patch specifically does not do anything with
definitions in bits/sigcontext.h, and nor does it condition any
inclusions of bits/sigcontext.h even where in fact that is not needed
on some architectures for the definitions of mcontext_t / ucontext_t.
As other namespace issues in these headers remain, this patch does not
fix bug 21457, nor allow any XFAILs to be removed.
Tested with build-many-glibcs.py.

list element.

Fix rawmemchr build with GCC 8.
The default rawmemchr implementation uses memchr with size (size_t)-1,
which produces a warning with current GCC mainline. The warning seems
reasonable for normal code, so this patch uses the DIAG_* macros to
disable it.
Tested (compilation of glibc only) with build-many-glibcs.py for
arm-linux-gnueabi and powerpc64le-linux-gnu, two architectures for
which the build was previously failing. Note that the glibc testsuite
will still fail to build with GCC mainline because of
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=80669>.
* string/rawmemchr.c: Include <libc-diag.h>.
(RAWMEMCHR): Disable -Wstringop-overflow around call to memchr

Remove MIPS32 accept4, recvmmsg, sendmmsg implementations.
MIPS32 has its own implementations of accept4, recvmmsg and sendmmsg
because at one point it needed to avoid socketcall being used for
those functions (MIPS32 has socketcall, but has never used it in
glibc, and so never had socket.S at the time when socketcall used such
a per-architecture file instead of C code). The current code no
longer uses socketcall based on __NR_socketcall being defined, and the
syscalls are always present on MIPS for supported kernels so the
socketcall case in the code is dead for MIPS; this patch removes the
implementations that are, as Adhemerval noted, no longer needed.
Tested compilation for mips-linux-gnu with build-many-glibcs.py.

Simplify accept4, recvmmsg, sendmmsg code.
The accept4, recvmmsg and sendmmsg functions had macros
__ASSUME_*_SYSCALL_WITH_SOCKETCALL. Before we could assume kernels
with the relevant functionality, these macros represented the
conditions under which, on a socketcall architecture, glibc could just
call the syscall unconditionally and not have to deal with socketcall
at all for those functions, because if the syscall didn't work for
them the socketcall call wouldn't either.
Now we can assume kernels with the relevant functionality, the only
question is whether we can assume the syscall is present; if not, we
are on a socketcall architecture and just use socketcall instead.
Thus, this patch removes the macros that are no longer necessary, and
simplifies the code for accept4, recvmmsg and sendmmsg to use the same
logic as the other C implementations of socket functions that may use
a syscall or socketcall depending on kernel support.
Tested for x86_64 and x86.

Move shared pthread definitions to common headers
This patch removes all the replicated pthread definition accross the
architectures and consolidates it on shared headers. The new
organization is as follow:
* Architecture specific definition (such as pthread types sizes) are
place in the new pthreadtypes-arch.h header in arch specific path.
* All shared structure definition are moved to a common NPTL header
at sysdeps/nptl/bits/pthreadtypes.h (with now includes the arch
specific one for internal definitions).
* Also, for C11 future thread support, both mutex and condition
definition are placed in a common header at
sysdeps/nptl/bits/thread-shared-types.h.
It is also a refactor patch without expected functional changes.

Simplify recvmmsg code.
Now we can assume a kernel with recvmmsg support, this patch
simplifies the implementation to be similar to that for accept4:
either using socketcall or the syscall according to whether the
syscall is known to be available, without further fallback
implementations.
(In fact further simplification is possible, getting rid of the
__ASSUME_*_SYSCALL_WITH_SOCKETCALL macros now that the minimum kernel
is guaranteed support for all of accept4, recvmmsg, sendmmsg, whether
through syscalls or through socketcall. I intend to do that for all
of accept4 / recvmmsg / sendmmsg together - so making their
implementations just like those for older socket functions - once the
basic cleanup for 3.2 minimum kernel is done for sendmmsg as well as
recvmmsg.)

Rename cppflags-iterator.mk to libof-iterator.mk, remove extra-modules.mk.
cppflags-iterator.mk no longer has anything to do with CPPFLAGS; all
it does is set libof-$(foo) for a list of files. extra-modules.mk

cppflags-iterator.mk a better name, removes extra-modules.mk, and
updates all uses of both.

Require Linux kernel 3.2 or later on x86 / x86_64.
As per the recent discussion, this patch implements a requirement for
Linux 3.2 or later for x86 and x86_64. This is only the initial
change to increase the configured minimum; it's expected that followup
patches would deal with associated removal of conditionals that are no
longer needed. If we remove the start-up test on the kernel version,
of course the NEWS and README text should then be revised (to reflect
that this version is just one such that glibc does not intend to
include compatibility code for any older kernel version, rather than
older kernels necessarily failing to work or glibc necessarily having
compatibility code for newer interfaces).
The followups would be able to assume presence of getcpu (x86_64),
recvmmsg (not always through its own syscall, sometimes only through
socketcall), sendmmsg (likewise), /proc/$pid/task/$tid/comm, f_flags
from statfs, prlimit64.
Tested for x86_64 and x86.

Fix network headers stdint.h namespace (bug 21455).
conform/ namespace tests of arpa/inet.h, netdb.h and netinet/in.h fail
for UNIX98 and XPG42 because of inclusion of stdint.h, which defines
macros not permitted in those headers for those standards. UNIX98
allows them to include inttypes.h, but (predating C99) has restricted
inttypes.h contents (not yet tested in the conform/ tests) not
including those macros; XPG4.2 has no such permission and no
inttypes.h / stdint.h at all.
This patch rearranges the headers to avoid this issue. intN_t
definitions move to bits/stdint-intn.h, and uintN_t definitions to
bits/stdint-uintn.h. (These are not bits/types/ headers because they
each define four types. They are separate rather than just a single
header because sys/types.h defines intN_t but u_intN_t rather than
uintN_t - and while sys/types.h could define uintN_t because of the
POSIX reservation of *_t, existing practice there is largely to
condition types on appropriate feature test macros, and indeed there
is at least one open bug report (14553) about a type that's not
so-conditioned, so maybe types there should actually have conditions
added where appropriate.) The affected network headers are then made
to include bits/stdint-uintn.h instead of stdint.h. This allows six
XFAILs to be removed.
This doesn't do anything about inttypes.h defining more than it should
for UNIX98, but we don't have conformtest expectations for that case
at present (and my inclination is that a fix for that should be as
local as possible - affecting only inttypes.h, not stdint.h, only for
the case of __USE_UNIX98 && !__USE_ISOC99).
Tested for x86_64.

Fix signal.h bsd_signal namespace (bug 21445).
signal.h declares bsd_signal for __USE_XOPEN. But this function was
obsoleted in the 2001 edition of POSIX and removed in the 2008
edition, so it should not be declared when the 2008 edition is in use.
This patch fixes the conditionals accordingly. (This does not fix any
conform/ test failures because of other namespace issues in signal.h.)
Tested for x86_64.

Use __glibc_reserved convention in mcontext, sigcontext (bug 21457).
This patch implements the most straightforward part of fixing
namespace issues for sys/ucontext.h and related headers: where fields
in sys/ucontext.h or bits/sigcontext.h are named "reserved", "padding"
or similar, they are renamed to use the __glibc_reserved* naming
convention. It does not change fields with a leading underscore, or
even those with a prefix such as uc_ or sc_. It only fixes a small
part of bug 21457, so no XFAILs are removed.
Tested for x86_64 and x86, and with build-many-glibcs.py.

x86: Set dl_platform and dl_hwcap from CPU features [BZ #21391]
dl_platform and dl_hwcap are set from AT_PLATFORM and AT_HWCAP very
early during startup. They are used by dynamic linker to determine
platform and build an array of hardware capability names, which are
added to search path when loading shared object. dl_platform and
dl_hwcap are unused on x86-64. On i386, i386, i486, i586 and i686
platforms were supported and only SSE2 capability was used.
On x86, usage of AT_PLATFORM and AT_HWCAP to determine platform and
processor capabilities is obsolete since all information is available
in dl_x86_cpu_features. This patch sets dl_platform and dl_hwcap from
dl_x86_cpu_features in dynamic linker. On i386, the available plaforms
are changed to i586 and i686 since i386 has been deprecated. On x86-64,
the available plaforms are haswell, which is for Haswell class processors
with BMI1, BMI2, LZCNT, MOVBE, POPCNT, AVX2 and FMA, and xeon_phi, which
is for Xeon Phi class processors with AVX512F, AVX512CD, AVX512ER and
AVX512PF. A capability, avx512_1, is also added to x86-64 for AVX512
ISAs: AVX512F, AVX512CD, AVX512BW, AVX512DQ and AVX512VL.

Bug 20686: Add address@hidden support.
Despite the fact that el_GR is ISO-8859-7:2003 which contains the euro
symobl, it is not possible to know this apriori to selecting the el_GR
locale. Therefore you don't know if el_GR can possibly have the 2003
ammendments which include the euro symbol. This is resolved by creating
an address@hidden locale similar to all the other @euro locales for non-UTF8
charsets.

This patch adds internal alias for __pread, __pread64, and __pwrite

powerpc64le: Create divergent sysdep directory for powerpc64le.
float128 on powerpc64le requires the addition of the ieee754/float128
sysdep, whereas powerpc64 doesn't. This requires creating a bunch of
submachine and cpu directories and Implies files which just point
towards their powerpc64 equivalent.

conformtest: Allow time.h inclusion from semaphore.h for XOPEN2K.
POSIX.1:2001 added sem_timedwait, but said nothing about defining
struct timespec in semaphore.h. The 2008 edition added a
corresponding permission to include <time.h> from <semaphore.h>.
Since this is the normal POSIX approach in such cases, it seems
appropriate to consider this a bug fix, and so this patch makes the
conform/ tests allow that inclusion for POSIX.1:2001 as well.
Tested for x86_64.
* conform/data/semaphore.h-data [XOPEN2K] (time.h): Allow header
inclusion.
* conform/Makefile (test-xfail-XOPEN2K/semaphore.h/conform):
Remove.

conformtest: Fix XPG standard naming.
The conform/ tests test -D_XOPEN_SOURCE under the name "XPG3", and
-D_XOPEN_SOURCE -D_XOPEN_SOURCE_EXTENDED under the name "XPG4".
That naming is misleading. _XOPEN_SOURCE_EXTENDED actually means
XPG4.2, including UX-shaded interfaces. _XOPEN_SOURCE actually means
XPG4, or XPG4.2 without UX-shaded interfaces. (Prior XPG versions
also used _XOPEN_SOURCE, but without any versioning of the values of
the macro, so XPG4.2 without UX-shaded interfaces is the only sensible
set of interfaces for glibc to expose given _XOPEN_SOURCE=1 without
_XOPEN_SOURCE_EXTENDED defined.)
This patch fixes the naming in the conform/ tests, so that what is now
called XPG4 is changed to XPG42, and what is now called XPG3 is
changed to XPG4.
Tested for x86_64 (and verified the complete set of expectations is
unchanged by the patch beyond the intended renaming).

Now there is a GCC 7 release branch, this patch makes

Relative to GCC 6, this fixes the MicroBlaze build but introduces ICEs
building glibc testcases for SH (GCC PRs 78459, 78460; the latter is
an out-of-memory issue so you may want to set memory limits when
running build-many-glibcs.py).

Fix sys/socket.h namespace issues from sys/uio.h inclusion (bug 21426).
sys/socket.h includes sys/uio.h to get the definition of the iovec
structure.
POSIX allows sys/socket.h to make all sys/uio.h symbols visible.
However, all of sys/uio.h is XSI-shaded, so for non-XSI POSIX this
results in conformtest failures (for sys/socket.h and other headers
that include it):
Namespace violation: "UIO_MAXIOV"
Namespace violation: "readv"
Namespace violation: "writev"
Now, there is some ambiguity in POSIX about what namespace
reservations apply in this case - see
http://austingroupbugs.net/view.php?id=1127 - but glibc convention
would still avoid declaring readv and writev, for example, for feature
test macros that don't include them (if only headers from the relevant
standard are included), even if such declarations are permitted, so
there is a bug here according to glibc conventions.
This patch moves the struct iovec definition to a new
bits/types/struct_iovec.h header and includes that from sys/socket.h
instead of including the whole of sys/uio.h. This fixes the namespace
issue; however, three files in glibc that were relying on the implicit
inclusion needed to be updated to include sys/uio.h explicitly. So
there is a question of whether sys/socket.h should continue to include
sys/uio.h under some conditions, such as __USE_XOPEN or __USE_MISC or
__USE_XOPEN || __USE_MISC, for greater compatibility with code that
(wrongly) expects this optional inclusion to be present there. (I
think the three affected files in glibc should still have explicit
sys/uio.h inclusions added in any case, however.)
Tested for x86_64.

conformtest: Allow *_t in sys/socket.h.
The conformtest expectations in sys/socket.h are missing the standard
POSIX allowance for all headers to define *_t names. For XSI standard
versions that allowance comes in via the permission to include
<sys/uio.h> (for which the expectations properly allow *_t), but for
non-XSI POSIX nothing brings in that allowance and spurious namespace
failures occur. This patch adds the required permission to the
expectations to remove the spurious failures (by itself this does not
allow any XFAILs to be removed).
Tested for x86_64.
* conform/data/sys/socket.h-data (*_t): Allow.

Macroize function declarations in math_private.h
This patch moves the declaration of many floating-point functions from
math_private.h to math_private_calls.h and macroize the declaration to
be dependent on floating-point type. For each of float, double, and
long double, the new header file is included once. This reduces the
amount of repetitive boilerplate that will be required when adding
float128 versions of these functions.
Tested for powerpc64le and s390x.

S390: Move utf8-utf32-z9.c to multiarch folder and use s390_libc_ifunc_expr
macro.
The utf8-utf32-z9.c iconv module is using ifunc and thus the ifunc part
should
be in multiarch folder. Otherwise ifunc is used even if you configure
with --disable-multi-arch.
This patch moves the ifunc resolvers to the new file
sysdeps/s390/multiarch/utf8-utf32-z9.c. The resolvers are now implemented
with s390_libc_ifunc_expr macro instead of using gcc attribute ifunc
directly.
The ifunc versions are implemented in sysdeps/s390/utf8-utf32-z9.c.
Each version is only implemented if needed or supported. Therefore there is
a block at beginning of the file which selects the versions which should be
defined depending on support for multiarch, vector-support and used minimum
architecture level. This block defines HAVE_[FROM|TO]_[C|CU|VX] to 1 or 0.
The code below is rearranged and surrounded
by #if HAVE_[FROM|TO]_[C|CU|VX] == 1. There is no functional change.
The cu instructions are z9 zarch instructions. As the major distros are
already using the newer z196 as architecture level set, those instructions
can be used as fallback version instead of the c-code. This behaviour is
decided at compile time via HAVE_S390_MIN_Z196_ZARCH_ASM_SUPPORT.

S390: Use new s390_libc_ifunc_expr macro in s390 8bit-generic.c.
This patch adds s390_libc_ifunc_expr macro which uses the __ifunc base macro
in include/libc-symbols.h and lets the user define a generic expression to
choose the correct ifunc variant. Furthermore as the base macro is used,
the ifunc resolver functions are now also using inhibit_stack_protector.
S390 needs its own version due to the hwcap argument of the ifunc resolver.
This new macro is now used in iconv code in 8bit-generic.c instead of using
gcc attribute ifunc directly.

Do not use wildcard symbol names for public versions in Versions files.
As noted in
<https://sourceware.org/ml/libc-alpha/2012-12/msg00240.html>,
stdlib/Versions and wcsmbs/Versions list some functions as
__strto*_internal and __wcsto*_internal rather than explicitly listing
the symbols to be exported (so any new internal function matching one
of those patterns would be wrongly added to version GLIBC_2.0), which
seems like a bad idea. This patch changes those files to list the
exported symbols explicitly. There are still entries in
sysdeps/nacl/Versions for __nacl_irt_*, but as GLIBC_PRIVATE symbols
that seems less significant.
Tested with build-many-glibcs.py that installed stripped shared
libraries are unchanged by the patch.

Fix missing timespec definition for sys/stat.h (BZ #21371)
As indicated by the bug report, the 'struct timespec' definition
is not defined for '_XOPEN_SOURCE=700' and '_POSIX_C_SOURCE=200112L'.
It is because current code only includes its definition if __USE_ATFILE
is defined and the define is only set with:
1. _GNU_SOURCE and/or _ATFILE_SOURCE definition.
2. _POSIX_C_SOURCE >= 200809L
However, the 'st_*' fields in 'struct stat' are defined if __USE_XOPEN2K8.
This patch uses the same logic for 'struct timespec' inclusion.
Tested on x86_64-linux-gnu.
* io/sys/stat.h: Use __USE_XOPEN2K8 insteaf of __USE_ATFILE for
struct timespec definition.

Assume that accept4 is always available and works
Simplify the Linux accept4 implementation based on the assumption
that it is available in some way. __ASSUME_ACCEPT4_SOCKETCALL was
previously unused, so remove it.
For ia64, the accept4 system call (and socket call) were backported
in kernel version 3.2.18. Reflect this in the installation
instructions.

Fix bits/socket.h IOC* namespace issues (bug 21267).
sysdeps/unix/sysv/linux/bits/socket.h includes asm/socket.h. That
includes asm/sockios.h, which on MIPS includes asm/ioctl.h, resulting
in namespace violations from IOC* macros.
bits/socket.h already has code to handle asm/socket.h unconditionally
defining macros that are only wanted for __USE_MISC. This patch
extends it to handle the IOC* macros as well (always undefining them
if not defined when bits/socket.h was included, as I don't think they
are part of the intended API even for __USE_MISC).
It's possible there should also be a kernel fix - it's not clear to me
that IOC* belong in the uapi headers, and even if they do they might
best be split out into another header to avoid getting defined by this
particular path. But since glibc needs to deal with existing kernel
headers, it also seems appropriate to extend the existing workaround
to these macros.
Tested (compilation only) with build-many-glibcs.py.

x86: Use AVX2 memcpy/memset on Skylake server [BZ #21396]
On Skylake server, AVX512 load/store instructions in memcpy/memset may
lead to lower CPU turbo frequency in certain situations. Use of AVX2
in memcpy/memset has been observed to have improved overall performance
in many workloads due to the higher frequency.
Since AVX512ER is unique to Xeon Phi, this patch sets Prefer_No_AVX512
if AVX512ER isn't available so that AVX2 versions of memcpy/memset are
used on Skylake server.

Consolidate Linux mmap implementation (BZ#21270)
This patch consolidates all Linux mmap implementations on default
sysdeps/unix/sysv/linux/mmap{64}.c one. To accomodate all required
architecture specific requeriments a new internal header is created
(mmap_internal.h) where each architecture add its specific code
requirements. Currently only x86_64 (to define MMAP_PREPARE to add
MAP_32BITS), s390 (which have a different kernel ABI for mmap), m68k
(which have variable minimum page sizes), and MIPS n32 (which zero
extend the offset to handle negative one correctly) redefine the new
header.
The patch also fixes BZ#21270 where default mmap64 on architectures
which uses mmap2 silent truncates large offsets value (larger than
1 << (page shift + 8 * sizeof (off_t)) or 1<<44 on architectures with
4096 bytes page size). The new consolidate implementation returns
EINVAL as allowed by POSIX.
It also adds a tests for on current tst-mmap-offset one. I have run
a full make check on x86_64, x86_64-32, i686, aarch64, armhf, powerpc,
powerpc64le, sparc64, and sparcv9 without any regressions. I also ran
some basic tests (tst-mmap-offset) on sh4, m68k, and on qemu simulated
MIPS32 and MIPS64.

getopt: eliminate __need_getopt by splitting up getopt.h.
__need_getopt is misnamed; what it really means is "we want only the
getopt features specified in POSIX, not the GNU extensions". Because
this code is shared with gnulib, it winds up being cleanest to split
getopt.h into *four* headers. getopt_core.h and getopt_ext.h will
be shared with gnulib, getopt_posix.h will be just for glibc, and
each project will have its own copy of getopt.h.

New files, intended to be shared with gnulib.

getopt: merge _GL_UNUSED annotations from gnulib
gnulib now has annotations on at least some functions to cater to
compilation with -Wunused-parameter. In order to follow suit cleanly,
I've added to libc-symbols.h some of the _GL_* macros that
gnulib-common.m4 puts into config.h. (I don't think they belong in
sys/cdefs.h, at least not without further thought.)
At this point all gnulib-side changes to getopt.c have been merged.
* include/libc-symbols.h: For gnulib compatibility, define
_GL_UNUSED, _GL_UNUSED_LABEL, _GL_ATTRIBUTE_PURE, and
_GL_ATTRIBUTE_CONST.
* posix/getopt.c (_getopt_initialize): Mark argc and argv
parameters with _GL_UNUSED.

getopt: merge from gnulib: alloca avoidance
In one place, glibc's getopt uses alloca to construct a linked list of
possibilities for an "ambiguous" long option. In gnulib, malloc
should be used instead. Providing for both cases complicates things a
fair bit. Instead of merging straight across, therefore, I have
chosen to rewrite it using a boolean vector instead of a linked list.
There is then only one allocation that might need freeing; in glibc it
can honor __libc_use_alloca as usual, and in gnulib we define
__libc_use_alloca to always be false, so we don't need ifdefs in the
middle of the function. This should also be slightly more efficient
in the normal case of long options being fully spelled out -- I think
most people aren't even aware they _can_ sometimes abbreviate long
options.
One interesting consequence is that the list of possibilities is now
printed in exactly the order they appear in the list of long options,
instead of the first possibility being shuffled to the end. This
shouldn't be a big deal but it did break one test that relied on the
exact text of this error message.
(The reason the previous patch was "in aid of" merging from gnulib is
I didn't want to have to make this change in two places.)
(The patch looks bigger than it really is because there's a fair bit
of reindentation and code rearrangement.)
* posix/getopt.c: When used standalone, define __libc_use_alloca
as always false and alloca to abort if called.
(process_long_option): Rewrite handling of ambiguous long options
to use a single boolean vector, not a linked list; use
__libc_use_alloca to decide whether to allocate this using alloca.
* posix/tst-getopt_long1.c: Adjust text of expected error message.

getopt: tidy up _getopt_initialize a bit
_getopt_data.__posixly_correct is completely redundant to
_getopt_data.__ordering, and some work that logically belongs in
_getopt_initialize was being done by _getopt_internal_r, making the
code harder to understand.
As a side effect, getenv will no longer be called if the first
character of the options string is '+' or '-', which is probably a
Good Thing. (Perhaps we should have a flag character that
specifically asks for the permutation behavior?)
* posix/getopt_int.h (_getopt_data): Remove __posixly_correct field.
* posix/getopt.c (_getopt_internal_r): Move some initialization code...

getopt: merge from gnulib: function prototype adjustments
For standards compliance, getopt, getopt_long, and getopt_long_only in
glibc have to take 'char *const *argv' even though they can mutate the
array. gnulib has tried to clean this up as much as possible: all the
internal functions use 'char **argv', and when used standalone, so do
getopt_long and getopt_long_only.
Also brought over are __nonnull annotations, corrections to documentation,
and apparently it is no longer necessary to worry about conflicting
prototypes for getopt. The macroification of the definitions of
getopt and __posix_getopt goes beyond what is currently in gnulib.
At this point getopt1.c and getopt_int.h are identical to their gnulib
versions.
* posix/getopt.h: Add backup definition of __nonnull for
consistency with gnulib. Define __getopt_argv_const to const
if not already defined.
(getopt): Update doc comment from gnulib. Prototype
unconditionally. Add __nonnull annotation.
(__posix_getopt): Add __nonnull annotation.
(getopt_long, getopt_long_only): Use __getopt_argv_const in
prototypes for consistency with gnulib. Add __nonnull
annotations.
* posix/getopt.c (_getopt_initialize, _getopt_internal_r)
(getopt_internal): Change 'argv' argument to type 'char **'.
Remove now-unnecessary casts.
(getopt, __posix_getopt): Eliminate repetition with a macro.
Cast 'argv' to 'char **' when calling _getopt_internal.
* posix/getopt1.c (getopt_long, getopt_long_only):
Use __getopt_argv_const for consistency with gnulib.
Cast 'argv' to 'char **' when calling _getopt_internal.

getopt: clean up error reporting
getopt can print a whole bunch of error messages, and when used
standalone (from gnulib) it uses fprintf to do that. But fprintf is a
cancellation point and getopt isn't, and also applying fprintf to a
stream in wide-character mode is not allowed.
glibc has an internal function called __fxprintf that writes a narrow
format string to a stream regardless of mode, but it only handles
ASCII format strings, and it's still a cancellation point. getopt's
messages are translated, so they might not be ASCII. So getopt has an
error message to an asprintf buffer, monkeys with internal flag bits
on stderr to disable cancellation, and then calls
__fxprintf(stderr, "%s", buffer). There isn't even a helper function,
the code is duplicated every time.
This patch fixes __fxprintf to handle arbitrary multibyte format
strings, and adds a variant __fxprintf_nocancel that does the same
thing but also isn't a cancellation point. (It still _works_ by
monkeying with internal flag bits on the FILE, but that's not really a
layering violation for code in stdio-common.) All of the #ifdef _LIBC
blocks can then be reduced to their standalone versions with a little
help from some macros at the top of the file.
I also wrote a test case to verify that getopt really isn't a
cancellation point, and I'm glad I did, because it found two bugs, one
of which wasn't even to do with cancellation (see previous patch).
* stdio-common/fxprintf.c (__fxprintf_nocancel): New function.
(locked_vfxprintf): New helper function. Handle arbitrary
multibyte strings, not just ASCII.
* include/stdio.h: Declare __fxprintf_nocancel.
* posix/getopt.c: When _LIBC is defined, define fprintf to
__fxprintf_nocancel, flockfile to _IO_flockfile, and
funlockfile to _IO_funlockfile. When neither _LIBC nor
_POSIX_THREAD_SAFE_FUNCTIONS is defined, define flockfile and
funlockfile as no-ops. (_getopt_internal_r): Remove all
internal #ifdef _LIBC blocks; the standalone error-printing
code can now be used for libc as well. Add an
flockfile/funlockfile pair around one case where the error
message is printed in several chunks. Don't use fputc.
* posix/tst-getopt-cancel.c: New test.
* posix/Makefile: Run it.

getopt: fix fencepost error in ambiguous-W-option handling
getopt_long contains an undocumented (AFAICT) feature in which, if you
put "W;" in the short-options list, then '-W foo' and '-Wfoo' are
treated as equivalent to '--foo'. This is implemented with a partial
second copy of the code for handling long options, and that code
increments optind one too many times when recovering from an ambiguous
abbreviated option, which can cause the main loop to walk past the end
of argv and crash.
I discovered this while writing a test case that tries to exercise all
of getopt's error reporting paths; I wouldn't be surprised to learn
that this feature is never used by real applications.
* posix/getopt.c (_getopt_internal_r): Don't increment
d->optind a second time when reporting ambiguous -W options.

getopt: remove USE_NONOPTION_FLAGS
glibc's implementation of getopt includes code to parse an environment
variable named _XXX_GNU_nonoption_argv_flags_ (where XXX is the
current process's PID in decimal); but all of it has been #ifdefed out
since 2001, with no official way to turn it back on.
According to commentary in our config.h.in, bash version 2.0 set this
environment variable to indicate argv elements that were the result of
glob expansion and therefore should not be treated as options, but the
feature was "disabled later" because "it caused problems". According
to bash's CHANGES file, "later" was release 2.01; it gives no more
detail about what the problems were.
Version 2.0 of bash was released on the last day of 1996, and version
2.01 in June of 1997. Twenty years later, I think it is safe to
assume that this environment variable isn't coming back.
* config.h.in (USE_NONOPTION_FLAGS): Remove.

sparc: Fix .udiv plt on libc
With the removal of divdi3 object from sparcv9-linux-gnu build, its
definition came from libgcc and its functions internall calls .udiv.
Since glibc also exports these symbols for compatibility reasons, it
will end up creating PLT calls internally in libc.so.
To avoid it, this patch uses the linker option --wrap to replace all
the internal libc.so .udiv calls to the wrapper __wrap_.udiv. Along
with strong alias in the udiv implementations, it makes linker do
local calls.
Checked on sparcv9-linux-gnu.
* sysdeps/sparc/sparc32/Makefile (libc.so-gnulib): New rule.
* sysdeps/sparc/sparc32/sparcv8/udiv.S (.udiv): Make a strong_alias

Build divdi3 only for architecture that required it
As noted in [1], divdi3 object is only exported in a handful ABIs
(i386, m68k, powerpc32, s390-32, and ia64), however it is built
for all current architectures regardless.
This patch refact the make rules for this object to so only the
aforementioned architectures that actually require it builds it.
Also, to avoid internal PLT calls to the exported symbol from the
module, glibc uses an internal header (symbol-hacks.h) which is
unrequired (and in fact breaks the build for architectures that
intend to get symbol definitions from libgcc.a). The patch also
changes it to create its own header (divdi3-symbol-hacks.h) and
adjust the architectures that require it accordingly.
I checked the build/check (with run-built-tests=no) on the
following architectures (which I think must cover all supported
ABI/builds) using GCC 6.3:
aarch64-linux-gnu
alpha-linux-gnu
arm-linux-gnueabihf
hppa-linux-gnu
ia64-linux-gnu

.udiv) which I address in next patch in the set. It also correctly
build SH with GCC 7.0.1 (without any regression from c89721e25d).

Add page tests to string/test-strnlen.
May be tricky for otimized implementations to handle strings around
page boundary once, for instance, it is performed unaligned loads or
when maxlen is used as a hint for vectorized loops. The test cases
should unveil regression bugs on these cases.
To some extend do_random_tests in string/test-strnlen tests strings
placed at page end but it does not cover all cases. So this change
adds tests which consists of placing strings of varying sizes ending
at the page boundary. It also combines with different values of maxlen.
Tested on ppc64le and x86_64.
* string/test-strnlen.c (do_page_tests): New function
to check length of strings ending at the page boundary.

powerpc64: Add POWER8 strnlen
Added strnlen POWER8 otimized for long strings. It delivers
same performance as POWER7 implementation for short strings.
This takes advantage of reasonably performing unaligned loads
and bit permutes to check the first 1-16 bytes until
quadword aligned, then checks in 64 bytes strides until unsafe,
then 16 bytes, truncating the count if need be.
Likewise, the POWER7 code is recycled for less than 32 bytes strings.

S390: Clobber also r14 in TLS_LD, TLS_GD macros on 31bit.
This patch also clobbers r14 in TLS_LD, TLS_GD macros on 31bit.
This ensures that r14 isn't used to save and restore r12 while
r14 is clobbered by the bas-instruction.
As note:
r12 can't be added to clobber list as gcc would fail with:
error: PIC register clobbered by â12â in âasmâ
For 64bit this fix was already done in 2004 in the
commit b80af23ac6973e69df6cd23d221fa44fffb21e17.
ChangeLog:
* sysdeps/s390/s390-32/tls-macros.h (TLS_LD, TLS_GD):

posix_spawn: use a larger min stack for -fstack-check [BZ #21253]
When glibc is built with -fstack-check, trying to use posix_spawn can
lead to segfaults due to gcc internally probing stack memory too far.
The new spawn API will allocate a minimum of 1 page, but the stack
checking logic might probe a couple of pages. When it tries to walk
them, everything falls apart.
The gcc internal docs [1] state the default interval checking is one
page. Which means we need two pages (the current one, and the next
probed). No target currently defines it larger.
Further, it mentions that the default minimum stack size needed to
recover from an overflow is 4/8KiB for sjlj or 8/12KiB for others.
But some Linux targets (like mips and ppc) go up to 16KiB (and some
non-Linux targets go up to 24KiB).
Let's create each child with a minimum of 32KiB slack space to support
them all, and give us future breathing room.
No test is added as existing ones crash. Even a simple call is
enough to trigger the problem:
char *argv[] = { "/bin/ls", NULL };
posix_spawn(NULL, "/bin/ls", NULL, NULL, argv, NULL);

Fix more test-errno issues
This patch fixes some test-errno-linux unexpected returns for the
tested syscalls on some older kernels (I saw it on a Linux 3.8 on
armv7l). Basically:
- inotify_add_watch: Linux v3.8 (676a0675c) removed the test to
check at least one valid bit in flags (to return EINVAL). It
was later added back in v3.9 (04df32fa1).

CONFIG_QUOTA.

Fix i686 memchr overflow calculation (BZ#21182)
This patch fixes the regression added by 23d2770 for final address
overflow calculation. The subtraction of the considered size (16)
at line 120 is at wrong place, for sizes less than 16 subsequent
overflow check will not take in consideration an invalid size (since
the subtraction will be negative). Also, the lea instruction also
does not raise the carry flag (CF) that is used in subsequent jbe
to check for overflow.
The fix is to follow x86_64 logic from 3daef2c where the overflow
is first check and a sub instruction is issued. In case of resulting
negative size, CF will be set by the sub instruction and a NULL
result will be returned. The patch also add similar tests reported
in bug report.
Checked on i686-linux-gnu and x86_64-linux-gnu.

Define more termios.h macros unconditionally for alpha (bug 21277).
termios.h should define IUCLC for UNIX98 and older XSI standards. The
sysdeps/unix/sysv/linux/alpha version defines it only if __USE_MISC,
so causing some conform/ tests to fail.
Other versions define it unconditionally (I* being a reserved
namespace for this header); the API should be consistent between
architectures in the absence of a clear reason for it to differ (and
given that a symbol is part of the API on two architectures, I don't
see any reason for the feature test macros required ever to differ
between those architectures), so this patch makes the alpha version
define it unconditionally as well. Two non-POSIX macros alongside it,
IMAXBEL and IUTF8, are also defined unconditionally on other
architectures, so this patch makes them consistent by defining them
unconditionally on alpha as well.
Tested (compilation only) with build-many-glibcs.py.

x86-64: Improve branch predication in _dl_runtime_resolve_avx512_opt [BZ
#21258]
On Skylake server, _dl_runtime_resolve_avx512_opt is used to preserve
the first 8 vector registers. The code layout is
if only %xmm0 - %xmm7 registers are used
preserve %xmm0 - %xmm7 registers
if only %ymm0 - %ymm7 registers are used
preserve %ymm0 - %ymm7 registers
preserve %zmm0 - %zmm7 registers
Branch predication always executes the fallthrough code path to preserve
%zmm0 - %zmm7 registers speculatively, even though only %xmm0 - %xmm7
registers are used. This leads to lower CPU frequency on Skylake
server. This patch changes the fallthrough code path to preserve
%xmm0 - %xmm7 registers instead:
if whole %zmm0 - %zmm7 registers are used
preserve %zmm0 - %zmm7 registers
if only %ymm0 - %ymm7 registers are used
preserve %ymm0 - %ymm7 registers
preserve %xmm0 - %xmm7 registers
Tested on Skylake server.

Fix failing test malloc/tst-interpose-nothread with GCC 7.
The test malloc/tst-interpose-nothread fails on s390x if built
with GCC 7 and glibc commit "Remove the str(n)dup inlines
from string/bits/string2.h. Although inlining"
(ae65d4f3c3995279ca458c460ebf8bab1885fa03) with output:
error: free: 0x3fffdffa010: invalid allocation index: 0 (not less than 0)
The destructor check_for_allocations in malloc/tst-interpose-aux.c is
called twice. One time after the test-child-process has finished
successfully
and once after the test-parent-process finishes.
During the latter invocation, allocation_index == 0. GCC 7 is now inlining
the
free function and calls unconditionally fail in get_header as
header->allocation_index (type == size_t) is always >= allocation_index (=
0).
Before the mentioned commit above, strdup was replaced by strlen, malloc and
memcpy. The malloc call was also inlined and allocation_index was set to
one.
This patch moves the already existing compiler barrier before the invocation
of free.
ChangeLog:
* malloc/tst-interpose-aux.c (check_for_allocations):
Move compiler barrier before free.

linux ttyname and ttyname_r: do not return wrong results
If a link (say /proc/self/fd/0) pointing to a device, say /dev/pts/2, in a
parent mount namespace is passed to ttyname, and a /dev/pts/2 exists (in a
different devpts) in the current namespace, then it returns /dev/pts/2.
But /dev/pts/2 is NOT the current tty, it is a different file and device.
Detect this case and return ENODEV. Userspace can choose to take this as a
hint
that the fd points to a tty device but to act on the fd rather than the
link.

Make alpha termios.h define IXANY unconditionally (bug 21259).
sysdeps/unix/sysv/linux/alpha/bits/termios.h defines IXANY only if
__USE_MISC. But it's in the base standard for POSIX.1:2008, and
XSI-shaded in previous standards. This patch makes the header define
it unconditionally, like other versions of this header do (it's always
reserved by standards that don't require it, so defining
unconditionally is OK by the standards).
Tested (compilation only) for alpha with build-many-glibcs.py. Note
that there are still termios.h conformtest failures after this patch
because of other issues with the alpha version of this header.
[BZ #21259]

conformtest: Add mips XFAIL for struct stat st_dev type (bug 17786).
As noted in bug 17786, MIPS o32 struct stat has the wrong type of
st_dev. This patch XFAILs that test in the conformtest expectations
for this case (the test still fails after the patch because there's
also a similar issue for st_rdev that needs reporting and XFAILing
separately, and the bug should not be closed without an actual fix,
not just XFAILing).
Tested for mips with build-many-glibcs.py.

As noted in bug 21260, sysdeps/unix/sysv/linux/alpha/bits/netdb.h

correct uint32_t. This patch XFAILs that test in the conformtest

conformtest: Skip execution tests when cross-compiling.
This patch makes conformtest skip execution tests when
cross-compiling, as an interim step towards running most of these
tests (presently disabled) in that case. It omits the (obvious)
Makefile change to actually enable the conformtest tests when
cross-compiling, as there are still enough failures seen with
build-many-glibcs.py that I'd like to get the results cleaner before
enabling these tests.
Tested for x86_64, and with the tests actually enabled for
cross-compilation with build-many-glibcs.py.
* conform/conformtest.pl ($cross): New variable.
(--cross): New command-line option.
(runtest): Skip test execution when cross-compiling.

conformtest: Support system-specific XFAILs.
conformtest has an internal XFAIL mechanism to allow failures of
individual expectations to be ignored, so that known hard-to-fix
failures (e.g. those affecting ABIs or requiring kernel changes) do
not cause the overall tests to FAIL and so hide other failures from
the same (header, standard) pair.
Various such bugs are system-specific, so this patch adds a mechanism
to allow system-specific XFAILs. A system-independent XFAIL is
achieved by putting "xfail-" at the start of the relevant expectation
in the *-data files. A system-specific XFAIL instead uses
"xfail[cond]-", where "cond" is a condition listed in
conformtest-xfail-conds in a sysdeps makefile (so one for x32 might
set conformtest-xfail-conds = x86_64-x32-linux, for example, and then
an expectation for tv_nsec's type could use
xfail[x86_64-x32-linux]-). The actual names are arbitrary, just
needing to match between the makefiles and the expectations, and if
necessary you can use "xfail[cond1|cond2]-" for a test that is
expected to fail under multiple conditions. As with
system-independent XFAILs, I think system-specific ones should have a
bug filed in Bugzilla and a comment referencing that bug.
Tested for x86_64, including with test expectations and makefiles
changed to use the new facility.
* conform/conformtest.pl ($xfail_str): New variable.
(--xfail=): New command-line option.
(top level): Handle expectations starting xfail[cond]-.
* conform/Makefile (conformtest-xfail): New variable.

conformtest: Make more tests into compilation tests.
The conformtest header tests test some things through compilation
tests and others through execution tests. This patch makes more of
the tests into compilation tests, using _Static_assert (note: for
float.h tests on floating-point values this is depending on a GNU
extension, that those assertions are allowed in the absence of
-pedantic although they aren't strictly integer constant expressions).
The remaining execution tests are for values of things listed as
"symbol" (in fact no such things have a value expectation listed) and
for values of macros defined as string constants (three such values
listed in total).
This is intended as preparation for enabling the vast bulk of the
tests to run for cross compilation. (Even the few remaining execution
tests ought in principle to run for cross compilation when a test
wrapper is defined, but that's more complicated. The existing
execution tests for native builds in fact are linked and run with an
existing installed libc that's required to exist to link against,
rather than with the newly built libc; only the new headers are used.)
Tested for x86_64.
* conform/conformtest.pl: Use compilation instead of execution
tests for testing values of constants and usability in #if.

Remove C++ namespace handling from glibc headers.
glibc headers include some code (not particularly consistent or
systematic) to put various declarations in C++ namespaces std and
__c99, if _GLIBCPP_USE_NAMESPACES is defined.
As noted in <https://gcc.gnu.org/ml/libstdc++/2017-03/msg00025.html>,
this macro was removed from libstdc++ in 2000. I don't expect
compilation with such old versions of libstdc++ to work with current
glibc headers anyway (whereas old *binaries* are expected to stay
working with current glibc); this patch (which should be a no-op with
any libstdc++ version postdating that removal) removes all this code
from the glibc headers.
The begin-end-check.pl test, whose comments say it is about checking
these namespace macro calls, is also removed. The code in that test
would have covered __BEGIN_DECLS / __END_DECLS as well, but if those
weren't properly matched it would show up with the
check-installed-headers-cxx tests, so I don't think there is an actual
use for keeping begin-end-check.pl with the namespace code removed.

shared libraries are unchanged by the patch).

Improve float range reduction accuracy near pi/2 (bug 21094).
Bug 21094 reports 3ulp errors of cosf and tanf for certain arguments
near pi/2 arising from the use of an insufficiently accurate range
reduction. (To be clear, this is a quality-of-implementation issue
relating to the apparent intent of those particular cosf and tanf
implementations; 3ulp is within the general glibc accuracy goals, so
not inherently a bug.)
This patch fixes that error by making a wider range of cases use the
existing more accurate range reduction for arguments close to pi/2.
The wider range of values is still narrow enough for the "z -=
pio2_2;" in the more accurate case to be exact, as the code expects.
Tested for x86_64, x86 and mips64; no ulps updates needed (but at
least on mips64, the larger ulps were seen if the tests were added
without the substantive fix).
[BZ #21094]

hppa: Fix setting of __libc_stack_end
The binutils package was recently changed to fix -z relro support on hppa.
See ld/21000 for details:
https://sourceware.org/bugzilla/show_bug.cgi?id=21000
This exposed a problem with the _dl_start_user function in the RTLD_START
define. We need to set __libc_stack_end before it is made read only. For
this, we need to define DL_STACK_END. The offset of 0x160 gives the same
stack end as the code in _dl_start_user.

Fix combreloc test with BSD grep
The test for "-z combreloc" fails when cross-compiling on a machine
that uses BSD grep (e.g. on macos). grep complains about empty
subexpression and exits with non-zero status, which is interpreted
by configure as "not found". As a result, support for "-z combreloc"
(HAVE_Z_COMBRELOC) is not detected, leading to link failure on SPARC.
While there, replace fgrep with 'grep -F', as fgrep is non-POSIX.

Fix test-errno issues
This patch fixes multiple issues of test-errno.c (9a56f8718341):
- Rename Linux test-errno.c to test-errno-linux.c to avoid build
the same source for both tests.
- Add a mlock check for 32 bits build running on 64 bits kernels.
Althuough man pages states that mlock fails with EINVAL if final
address overflows, kernels does not return it for aforementioned
condition (it returns ENOMEM instead). Although it seems to be
a kernel issue for compat syscall handling, I think it is worth
to still check syscall return and document the behavior.
- Initialize option lenght for setsockopt check.
- Change open test from EINVAL to EISDIR.
Checked on x86_64-linux-gnu and i686-linux-gnu (running on 64 bits
kernel).

Fix test-math-vector-sincos.h aliasing.
x86_64 libmvec tests have been failing to build lately with GCC
mainline with -Wuninitialized errors, and Markus Trippelsdorf traced
this to an aliasing issue
<https://sourceware.org/ml/libc-alpha/2017-03/msg00169.html>.
This patch fixes the aliasing issue, so that the vectors-of-pointers
are initialized using a union instead of pointer casts. This also
fixes the testsuite build failures with GCC mainline.
Tested for x86_64 (full testsuite with GCC 6; testsuite build with GCC
mainline with build-many-glibcs.py).

Split helper classification macros from mathcalls.h
The classification macros: finite, fpclassify, iseqsig, isinf, isnan,
issignaling, and signbit are defined by ISO C11 and declared in
mathcalls.h for each of the floating-point types: float, double, and
long double.
TS 18661-3 does not mention these macros for float128, however support
for them must be present when _Float128 is present. This is true,
even when the feature test macro __STDC_WANT_IEC_60559_TYPES_EXT__ is
false. Other function declarations in mathcalls.h, on the other hand,
depend on __STDC_WANT_IEC_60559_TYPES_EXT__.
This patch splits the helper functions (__finite, __fpclassify,
__iseqsig, __isinf, __isnan, __issignaling, and __signbit) from
mathcalls.h, so that these helper functions can be declared for
_Float128, even when __STDC_WANT_IEC_60559_TYPES_EXT__ is false.
Tested for powerpc64le, s390x, and x86_64.

build-many-glibcs: Remove no_isolate from SH config
Now with d40dbe7 SH build does not require more the no_isolate gcc
options to correct build glibc (since SH build now does not generate
a trap anymore). This patch removes the unrequired options from
SH config.
Checked with a build for sh3-linux-gnu, sh3eb-linux-gnu, sh4-linux-gnu,
and sh4eb-linux-gnu.
* scripts/build-many-glibcs.py (Context.add_all_configs): Remove
no_isolate usage for SH.

Remove the str(n)dup inlines from string/bits/string2.h. Although inlining
calls with constant strings shows a small (~10%) performance gain, strdup is
typically used in error reporting code, so not performance critical.
Remove the now unused __need_malloc_and_calloc related defines from
stdlib.h.
Rename existing uses of str(n)dup to __str(n)dup so it no longer needs to be
redirected to a builtin. Also building GLIBC with -Os now no longer shows
localplt or linkname space failures (partial fix for BZ #15105 and BZ
#19463).

Add more IPV6_* macros to sysdeps/unix/sysv/linux/bits/in.h.
Linux 4.10 adds IPV6_RECVFRAGSIZE to include/uapi/linux/in6.h, which
shows that several such IPV6_* macros are missing from glibc's
sysdeps/unix/sysv/linux/bits/in.h (while older ones are present). I
don't know whether any of these might be deliberately omitted, but
this patch adds what appear to be the missing more recent macros to
glibc.

sh: Fix building with gcc5/6
Build glibc for sh4-unknown-linux-gnu currently fails if one's
using GCC5/6: in dl-conflict.c, the elf_machine_rela() function
is called with NULL as its 3rd argument, sym. The implementation
of that function in sysdeps/sh/dl-machine.h dereferences that pointer:
const Elf32_Sym *const refsym = sym;
...
if (map == &GL(dl_rtld_map))
value -= map->l_addr + refsym->st_value + reloc->r_addend;
GCC discovers a null pointer dereference, and in accordance with
-fdelete-null-pointer-checks (which is enabled in -O2) replaces this
code with a trap - which, as SH does not implement a trap pattern in
GCC, evaluates to an abort() call. This abort() call pulls many more
objects from libc_nonshared.a, eventually resulting in link failure
due to multiple definitions for a number of symbols.
As far as I see, the conditional before this code is always false in
rtld: _dl_resolve_conflicts() is called with main_map as the first
argument, not GL(_dl_rtld_map), but since that call is in yet another
compilation unit, GCC does not know about it. Patch that wraps this
conditional into !defined RESOLVE_CONFLICT_FIND_MAP attached.
* sysdeps/sh/dl-machine.h (elf_machine_rela): The condition
in R_SH_DIR32 case is always false when inlined from
dl-conflict.c. Ifdef out to prevent GCC from insertin an
abort() call.

Update auto-libm-test-out for catan / catanh.
I've used gmp 6.1.2, mpfr 3.1.5 and upstream mpc with fix in mpc_atan

Regenerate MIPS catan, catanh long double ulps.
This patch regenerates MIPS catan and catanh ulps for long double with
fixed expected results for the tests of those functions. ulps for
other types (which may see variation depending on whether glibc is
built for a processor with fused multiply-add support) are
deliberately not reduced. ulps are not regenerated for powerpc-nofpu
as such regeneration does not result in any changes for long double.
* sysdeps/mips/mips64/libm-test-ulps: Update catan and catanh ulps
for long double with corrected test expectations.

Consolidate Linux send implementation
This patch consolidates the send Linux syscall implementation on
sysdeps/unix/sysv/linux/send{to}.c. The changes are:
1. Remove send from auto-generation syscalls.list on the architecture

Ignore and remove LD_HWCAP_MASK for AT_SECURE programs (bug #21209)
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.
[BZ #21209]
* elf/rtld.c (process_envvars): Ignore LD_HWCAP_MASK for
AT_SECURE processes.
* sysdeps/generic/unsecvars.h: Add LD_HWCAP_MASK.
* elf/tst-env-setuid.c (test_parent): Test LD_HWCAP_MASK.
(test_child): Likewise.
* elf/Makefile (tst-env-setuid-ENV): Add LD_HWCAP_MASK.

hppa: set __IPC_64 as zero for SysV IPC calls
In 1e5834c38a22 ("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.

S390: Optimize atomic macros.
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
(USE_ATOMIC_COMPILER_BUILTINS): Define to 1.
(__arch_compare_and_exchange_val_8_acq,
__arch_compare_and_exchange_val_16_acq,

Narrowing the visibility of libc-internal.h even further.
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.
* include/libc-internal.h: Definitions of above macros
moved from here. Don't include libc-diag.h anymore either.

Miscellaneous low-risk changes preparing for _ISOMAC testsuite.
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.

sunrpc: Do not unregister services if not registered [BZ #5010]
The change in commit 718946816cf60374f9d8f674d3ed649fdb33205a
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.

sunrpc: Avoid use-after-free read access in clntudp_call [BZ #21115]
After commit bc779a1a5b3035133024b21e2f339fe4219fb11c
(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.

Allow direct use of math_ldbl.h in testsuite.
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.

Split DIAG_* macros to new header libc-diag.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.

DIAG_PUSH_NEEDS_COMMENT, DIAG_POP_NEEDS_COMMENT,

Clean up conditionals for declaration of gets.
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.

Run libm tests separately for each function.
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.

Add new templates for IEEE wrappers
Several wrappers for IEEE functions use _LIB_VERSION / matherr /
__kernel_standard functionality, which we want to obsolete. New
wrappers, such as for float128, must not use this functionality.
This patch adds new wrappers that only __set_errno and can be used by
the new float128 wrappers.
Tested for powerpc64le.

Add TFD_TIMER_CANCEL_ON_SET to sys/timerfd.h.
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.

Remove some unused libm-test exception macros.
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.

Rework -fno-omit-frame-pointer support on i386
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).

build-many-glibcs: don't crash if email is not configured
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

Make it so by skipping the mail step if mail isn't configured.

bot_config does not contain all of the necessary email-
related settings, just print a warning and continue.

Remove the str(n)cmp inlines from string/bits/string2.h. The strncmp
optimization seems unlikely to ever be useful, but if it occurs in
real code it should be added to GCC. Expanding strcmp of small strings
does appear useful (benchmarking shows it is 2-3x faster), so this would
be useful to implement in GCC (PR 78809).
* string/bits/string2.h (strcmp): Remove define.
(__strcmp_cg): Likewise.

The internal header include/string.h does not work in C++: it causes link
errors
in several C++ debug tests when any of the functions it declares are called.
The best option would be to not use internal headers for tests (unless
explicitly needed). Add guards so that it is safe to use include/string.h
from
C++.
* include/string.h: Add __cplusplus check.

Fix y0 and y1 exception handling for zero input [BZ #21134]
The Bessel functions of the second type (Yn) should raise the "divide
by zero" exception when input is zero (both positive and negative).
Current code gives the right output, but fails to set the exception.
This error is exposed for float, double, and long double when linking
with -lieee. Without this flag, the error is not exposed, because the
wrappers for these functions, which use __kernel_standard
functionality, set the exception as expected.
Tested for powerpc64le.

Move most libmvec test contents from .c to .h files.
The libmvec tests put substantive, architecture-specific contents in
.c files such as test-double-vlen4.c, so making those files
architecture-specific and causing issues for generating such files
automatically when splitting up tests by function.
This patch moves all the substantive contents to .h files, so the .c
files only include the .h file and then libm-test.c. This allows for
automatic generation of per-function .c files in future. The .h files
in turn #include or #include_next the architecture-independent file
and add the architecture-specific definitions to that. (Splitting by
function should in fact allow the TEST_VECTOR_* macros to be replaced
by sysdeps makefile information on which functions to test in each
case, removing the need for gen-libm-have-vector-test.sh as well as
removing the need for some of the architecture-specific headers.)
Tested for x86_64.

Move INIT_ARCH_EXT call from libm-test-support to libm-test-driver.
libmvec tests involve calling INIT_ARCH_EXT during initialization then
CHECK_ARCH_EXT before testing each function to see if the processor
being used for testing supports the required instruction set
extensions.
After my refactoring of libm-test infrastructure, the INIT_ARCH_EXT
call is in libm-test-support.c, built only once per floating-point
type. Now, in fact all definitions of this macro are empty, but given
that the definitions in sysdeps/x86_64/fpu/math-tests-arch.h are
conditional on REQUIRE_* macros defined in particular vector tests, it
seems more correct for the INIT_ARCH_EXT call to go instead in
libm-test-driver.c which gets built separately with those REQUIRE_*
macros properly defined. This patch moves the call there.
Tested for x86_64 and x86.

ldbl-128: Fix y0 and y1 for -Inf input [BZ #21130]
The Bessel functions of the second type (Yn) are not defined for
negative input and should return NAN with the "invalid" exception
raised, in these cases. However, current code checks for infinity and
return zero, regardless of the sign. This error is exposed for long
double when linking with -lieee. Without this flag, the error is not
exposed, because the wrappers for these functions, which use
__kernel_standard functionality, return the correct value.
Tested for powerpc64le.

GLIBC uses strchr (s, '\0') as an idiom to find the end of a string.
This is transformed into rawmemchr by the bits/string2.h header.
However this is generally slower than strlen on most targets, even when
an optimized rawmemchr implementation exists. Since GCC7 optimizes
strchr (s, '\0') to strlen (s) + s, the GLIBC headers should not
transform this to rawmemchr. As GCC recognizes strchr as a builtin,
defining strchr as the builtin is not useful.
* string/bits/string2.h (strchr): Remove define.

Move more csin, csinh tests to auto-libm-test-in.
When I moved tests of csin and csinh to auto-libm-test-in, I didn't
move a few tests for which gen-auto-libm-tests was very slow because
of MPC slowness on certain inputs.
Now that auto-libm-test-out has been split up, such slowness only
affects regenerating the test expectations for the individual
functions in question, rather than any addition of tests for any
function to auto-libm-test-in. Thus, I no longer consider it a
problem to have these inputs in auto-libm-test-in, and this patch
moves them there. This results in test generation for csin and csinh
taking 5m43s (for each of csin and csinh) on my system, while other
functions are unaffected.
I expect the test generation to be much faster in MPC 1.1 (the
relevant performance improvements went in MPC mainline in Dec 2013,
but there hasn't been a release from mainline since then).
Tested for x86_64 and x86.

Merge libm-compat-calls-auto and libm-compat-calls
Both libm-compat-calls and libm-compat-calls-auto list the functions
that must be built for the types float, double, and long double, but
not for other floating-point types that get added to libm. Besides
that, the use of libm-compat-calls-ldouble-yes to select if
w_lgamma_compatl and k_standardl should be built for long-double (in
libm-compat-calls) has the same effect of the use of type-foreach
(in libm-compat-calls-auto).
This patch merges the contents of libm-compat-calls into
libm-compat-calls-auto, then renames the latter to libm-compat-calls.
Tested for powerpc64le, s390, and x86_64.

Move -U__LIBC_INTERNAL_MATH_INLINES to test-math-inline.h.
The libm tests of inline functions undefine __NO_MATH_INLINES (from
math-CPPFLAGS) in test-math-inline.h, but __LIBC_INTERNAL_MATH_INLINES
via -U options in the makefile.
This is an odd inconsistency between the handling of the two macros.
It also depends on the ordering (in compilation commands) of the
various variables providing compiler options (which I think is why
it's using CPPFLAGS-*.c instead of CFLAGS-*.c).
This patch moves the undefine to test-math-inline.h, so improving
consistency and eliminating the dependency on the order in which
variables go in the compilation commands. The CPPFLAGS-*.c variables
are renamed to CFLAGS-*.c, matching those for the non-inline libm
function tests.
By moving the -U option to the header file, this should ensure that
ordering issues don't arise with a subsequent move of the options to
these tests to target-specific CFLAGS += ... variable settings (for
when tests for each function are build separately and so compilation
options need setting for many more makefile targets, for which
target-specific variable settings seem to be the most convenient form
to generate with iterators).
Tested for x86_64.

Build most libm-test support code once per type.
libm-test-driver.c contains various functions used in the course of
libm testing, which are built as part of each test using this
machinery.
Currently, these functions get built for three tests for each type
(e.g. test-float, test-ifloat, test-float-finite), plus the vector
function tests. All these tests are huge and thus slow to build; the
output of gen-libm-test.pl totals around 40 MB across all functions.
To make the individual tests built from the Makefile smaller, it makes
sense to split these tests up so the tests for each function are built
separately (thus, three tests for each (function, type) pair, plus
vector tests built only for functions that actually have vector
versions). This improves parallelism and means that if tests fail,
the summary of failed tests makes it more obvious where the problem
might be without needing to look in the .out files to see which
functions' tests failed (though architecture maintainers still need to
keep libm-test-ulps up to date to avoid spurious failures of little
interest).
Simply including libm-test-driver.c as-is in such individual-function
tests does not work because of unused static check_* functions (those
functions only being used for the types of the outputs of the function
under test). It also means the common code gets built over 1000 times
instead of nine (plus vector tests). To avoid that issue, this patch
splits out the bulk of the libm-test-driver.c code into a separate
file libm-test-support.c (with a few functions made non-static). That
separate file is built only once for each floating-point type (so at
present three times, or twice on architectures with long double =
double). Definitions needed in both libm-test-support.c and
libm-test-driver.c go in libm-test-support.h (it's possible some of
those are in fact only needed in one of the two files).
libm-test-driver.c keeps definitions of a limited number of variables
used to configure how libm-test-support.c behaves, various macros and
structures needed by individual-function tests, and the main function.
This move is also consistent in spirit with the move away from
test-skeleton.c having all the test support code, to a small
support/test-driver.c included in individual tests with most of the
code built separately.

Fix getting tunable values on big-endian (BZ #21109)
The code to set value passed a tunable_val_t, which when cast to
int32_t on big-endian gives the wrong value. Instead, use
tunable_val_t.numval instead, which can then be safely cast into
int32_t.

Add Linux PTRACE_EVENT_STOP
Add PTRACE_EVENT_STOP value to Linux's sys/ptrace.h, modify related
comments accordingly.
This constant initially appeared in Linux 3.1 (kernel commit 3544d72a,
"ptrace: implement PTRACE_SEIZE") but its value has changed later
in Linux 3.4 (kernel commit 5cdf389a, "ptrace: renumber
PTRACE_EVENT_STOP so that future new options and events can match").
The comment is also taken from the above commit.
This constant is used by e.g. strace, CRIU, Mozilla RR.

Clean up libm vector tests exception test disabling.
The libm vector tests disable tests of exception raising via defining
macros EXCEPTION_TESTS_float and EXCEPTION_TESTS_double to 0 in the
headers for individual vector lengths.
As EXCEPTION_TESTS is used in code in libm-test-driver.c that is
otherwise ready to be built only once per type, this is not a good
idea; it's better to define TEST_EXCEPTIONS appropriately so that
flag_test_exceptions then gets initialized appropriately.
Furthermore, it's better to do this just once, in test-math-vector.h,
since there is no actual dependence on the vector length or type.
This patch duly makes that change.
Tested for x86_64.

Fix powf inaccuracy (bug 21112).
Bug 21112 reports a case where powf is substantially inaccurate. This
results from a multiplication where cp_h*p_h is required to be exact,
and p_h is masked to have only 12 leading nonzero bits in its
mantissa, but the value of cp_h has the 13th bit nonzero, leading to
inexact multiplication results in some cases that can result in large
errors in the final result of powf. This patch fixes this by using a
value of cp_h correctly rounded to nearest to 12 bits, with a
corresponding updated value of cp_l.
Tested for x86_64 and x86.

powerpc: Improve strcmp performance for shorter strings
For strings >16B and <32B existing algorithm takes more time than default
implementation when strings are placed closed to end of page. This is due
to byte by byte access for handling page cross. This is improved by
following >32B code path where the address is adjusted to aligned memory
before doing load doubleword operation instead of loading bytes.
Tested on powerpc64 and powerpc64le.

Refactor some code in libm-test-driver.c.
Splitting libm tests by function will mean about a thousand such tests
built separately instead of the present nine (plus vector variants).
When this is done, it's desirable to avoid needing to build all the
test infrastructure so many times. Also, simply including
libm-test-driver.c as-is into per-function tests doesn't actually
work, because the various check_* functions are not used by all tests
and so generate errors for unused static functions.
Although some pieces of infrastructure depend on the type being tested
while others don't, building once per type seems the simplest
approach. This patch makes changes to libm-test-driver.c in
preparation for that. Various cases where functions directly use
macros such as TEST_ERRNO (that may vary depending on things other
than the type under test) are changed to use variables initialized
using those macros, while most of the code in main is moved out to
functions libm_test_init and libm_test_fini.
The idea is that all the functions in libm-test-driver.c will be moved
out in a subsequent patch to be built once per type (and be no longer
static when they are used from per-function tests), while
libm-test-driver.c remains containing definitions of various variables
(no longer static, of course, because they'll be used in the per-type
code) and the main function. Declarations / macros relevant to both
the once-per-type code and the per-function tests will go in a shared
header.
Tested for x86_64.

Move libm-test TEST_MSG definitions to libm-test-driver.c.
Various files using the libm-test infrastructure define a TEST_MSG
macro with an informal description of the tests being run.
This patch moves this macro to libm-test-driver.c (the definition
depending on other macros already defined), so files specific to
(type, choice of whether to test inline functions or finite-math-only
functions, vector length) no longer need to define it. This is in
preparation for replacing files such as test-float.c with per-function
test-float-<func>.c etc. automatically generated in the build
directory when tests are run.

Split libm-test.inc by function.
Continuing the process of splitting up libm tests into more reasonably
sized units, this patch splits libm-test.inc into 121 separate
libm-test-<function>.inc files, one per array of test data. (There
are 126 libm *_test functions, but five of those are for functions
that are aliases for test purposes and so share arrays of test data.)
In the present patch, the 121 files get processed separately by
gen-libm-test.pl, each using only the auto-libm-test-out-<function>
file that is relevant (/dev/null for functions not using
auto-libm-test-* at all). This effectively eliminates the
serialization on running gen-libm-test.pl. However, the resulting .c
files still all get #included together, so compiling the limited
number of libm tests using libm-test.inc may still act as a
serialization point (the compilations still all have 40 MB of code to
process). libm-test.inc doesn't actually have anything in it any more
that needs gen-libm-test.pl processing, but is left as a .inc file
that gets processed to produce a .c file, rather than being renamed,
since the intent of this patch is as an intermediate step before
libm-test.inc gets removed and tests get compiled separately for each
function being tested.
Tested for x86_64.
* math/libm-test.inc: Move all tests of individual functions to
libm-test-*.inc and #include libm-test-*.c files.

commit 4f1bc131db81042e8e8d1f829ed18e28d9c56b58

Split auto-libm-test-out by function.
math/auto-libm-test-out is, at over 30 MB, by far the largest file in
the glibc source tree. This patch splits it by function, so reducing
it to auto-libm-test-out-<func> files that are all under 5 MB in size.
This is preliminary to splitting up libm-test.inc as well so that each
function's tests can also be processed separately by
gen-libm-test.pl. As a preliminary patch it doesn't actually
implement that step; rather, all the separate files get concatenated
by the Makefile to produce the monolithic auto-libm-test-out file
again as an input to gen-libm-test.pl. (The concatentation is
identical to the file in the source tree before this patch.)
Even this preliminary step, however, is of use independent of
splitting up libm-test.inc: some tests for csin and csinh have not
been moved to auto-libm-test-in because they result in
auto-libm-test-out generation taking several minutes rather than a few
seconds (all released MPC versions are very slow for certain sin /
sinh inputs; there are some old improvements in MPC mainline which
should eventually become MPC 1.1, but the complex inverse trig and
hyperbolic functions are slow even in MPC mainline and have yet to be
moved to auto-libm-test-in at all), and it seems much more reasonable
to add such inputs to auto-libm-test-in when it will only slow down
regeneration for particular functions than when it will slow down
regeneration globally.
gen-auto-libm-tests still parses the whole input file, but only
generates output for the requested function. This ensures bad syntax
in the file is always detected, and parsing the whole file is quick;
it's output generation that is comparatively slow for some functions.

Eliminate libm-test.stmp.
math/Makefile uses libm-test.stmp to handle dependencies involving
multiple generated files all generated by a single sequence of
commands in a single Makefile rule.
Having separated the libm-test-ulps.h and libm-test.c generation into
separate runs of gen-libm-test.pl, there is now no need for a single
rule to generate multiple target files; each of the three target files
involved can be generated by a separate Makefile rule, meaning normal
dependencies on the individual files can be used and so libm-test.stmp
is not needed at all. This patch does just that, eliminating the
.stmp file, in further preparation for when there are many separate
libm-test-<func>.c files generated from libm-test-<func>.inc and the
dependencies are on just the relevant .c file in each case.
Tested for x86_64.
* math/Makefile (generated): Do not include libm-test.stmp.

Rework gen-libm-test.pl input/output handling.
This patch reworks how input and output files are specified for
gen-libm-test.pl.
Previously, the script had names of various inputs and outputs
hardcoded, with a -o option to specify an output directory. This
patch replaces this with all inputs and outputs being specified
explicitly as the arguments of options passed to the script. Outputs
are only generated if the relevant option is passed, and only the
processing required for the indicated outputs is done. The Makefile
is made to pass options for generating libm-test-ulps.h in a separate
invocation of gen-libm-test.pl from that generating libm-test.c.
This is all in preparation for splitting up libm-test.inc and
auto-libm-test-out and running tests separately for each function,
when gen-libm-test.pl will be run separately for each function to
generate the .c file but only once to generate libm-test-ulps.h (and
those runs will be able to be in parallel).
Tested for x86_64. The generated libm-test.c and libm-test-ulps.h are
identical before and after the patch. Also tested the "make
regen-ulps" case.

Move non-function-specific parts of libm-test.inc to separate file.
libm-test.inc contains both test infrastructure and tests of
individual functions.
This patch moves the infrastructure to a separate file
libm-test-driver.c. This is in preparation for splitting the tests of
individual functions into separate source files, which will be
processed individually by gen-libm-test.pl (so e.g. libm-test-acos.inc
and auto-libm-test-out-acos will be processed by gen-libm-test.pl to
produce libm-test-acos.c, and files such as test-double-acos.c will be
generated by the Makefile to include appropriate headers,
libm-test-driver.c and libm-test-acos.c so tests of each function get
run separately).
It is no doubt possible to split things up further, so that functions
not depending on the type being tested only get compiled once and most
of those depending on the type being tested get compiled once per type
(rather than separately for variants such as inline / no-inline, and
separately for each function being tested after that split), but this
rearrangement as-is seems a useful incremental step towards splitting
these tests by function.

Remove libm-test.inc comment listing functions tested and not tested.
math/libm-test.inc has a comment listing the functions tested and not
tested. The list of functions tested duplicates what is immediately
obvious from the rest of the file and adds another place to update
when adding a function. I've put the information about functions not
tested on the wiki todo list; this patch removes that comment, in
preparation for splitting tests of each function into separate .inc
files with common code staying in a separate .c file.
Tested for x86_64.

Do not hardcode list of libm functions in libm-err-tab.pl.
manual/libm-err-tab.pl contains a hardcoded list of libm functions for
which ulps are listed in the manual, and another hardcoded list in a
comment of functions deliberately excluded because of an expected lack
of ulps (and the two together are not in fact an exhaustive list of
libm functions tested through the libm-test machinery).
This patch removes these hardcoded lists, so eliminating this from the
places needing updating when a new libm function is added. Instead,
ulps are tabulated for functions for which they are seen in
libm-test-ulps files, in alphabetical order. The pseudo-function
names such as *_downward and *_vlen* are excluded since they are
excluded from the existing lists, and the description in the manual is
updated to explain how those entries are excluded and if a function is
not listed at all it does not have known errors.
Tested for x86_64.
* manual/libm-err-tab.pl (@all_functions): Change to
%all_functions. Initialize as empty.
(parse_ulps): Add to %all_functions based on functions found in
ulps files. Ignore results for non-default rounding modes and
vector functions.
(print_platforms): Use %all_platforms.
* manual/math.texi (Errors in Math Functions): Document omissions
from the table.

Remove before-compile setting in math/Makefile.
In <https://sourceware.org/ml/libc-alpha/2015-12/msg00543.html>,
Florian noted highly parallel builds being slowed down by
gen-libm-test.pl running during the build, when it should only run for
testing, not for building glibc itself.
This is a consequence of libm-test.c being listed in before-compile.
That listing in before-compile arose from the error reported in
<https://sourceware.org/ml/libc-hacker/1999-10/msg00054.html> when
building dependencies: at that time, dependencies were generated
separation from compilation, so if a source file included a generated
file it wasn't enough for the dependencies for the .o file to be
correct, the generated file needed to be listed in before-compile.
Since <https://sourceware.org/ml/libc-hacker/2003-05/msg00001.html>,
dependencies are generated as a side-effect of compilation. This
means that having the right dependencies for the .o files for the
tests fully suffices to ensure that libm-test.c is generated by the
time it's needed; no entry in before-compile is needed. And we indeed
have such a dependency for all the tests using libm-test.c:
$(addprefix $(objpfx), $(libm-tests.o)): $(objpfx)libm-test.stmp
Thus, the before-compile definition is unnecessary, and this patch
removes it. (This may of course move serialization from the glibc
build to glibc testing, but I intend to split up libm-test.inc so that
tests for each (floating-point type, libm function) pair are built and
run separately, which should reduce that serialization.)
Tested for x86_64.
* math/Makefile (before-compile): Remove.

sparc: Remove unused assignment in __clone
It is no longer needed to preserve the flags parameter to `clone' since
the commit c579f48edba88380635ab98cb612030e3ed8691e (Remove cached
PID/TID in clone).
Testing was performed successfully on sparcv9/Linux.
[BZ #21075]
* sysdeps/unix/sysv/linux/sparc/sparc64/clone.S (__clone): Remove
unused assignment.
* sysdeps/unix/sysv/linux/sparc/sparc32/clone.S (__clone): Likewise.

Add __glibc_unlikely hint in lll_trylock, lll_cond_trylock.
The macros lll_trylock, lll_cond_trylock are extended by an __glibc_unlikely
hint. Now the trylock macros are based on the same assumption about a
free/busy lock as lll_lock.
With the hint gcc emits code in e.g. pthread_mutex_trylock which does
not use jumps if the lock is free. Without the hint it had to jump away
if the lock is free.
Tested on s390x, ppc.
ChangeLog:
* sysdeps/nptl/lowlevellock.h (lll_trylock, lll_cond_trylock):
Add __glibc_unlikely hint.

Remove i686, x86_64, and powerpc strtok implementations
Based on comments on previous attempt to address BZ#16640 [1],
the idea is not support invalid use of strtok (the original
bug report proposal). This leader to a new strtok optimized
strtok implementation [2].
The idea of this patch is to fix BZ#16640 to align all the
implementations to a same contract. However, with newer strtok
code it is better to get remove the old assembly ones instead of
fix them.
For x86 is a gain in all cases since the new implementation can
potentially use sse2/sse42 implementation for strspn and strcspn.
This shows a better performance on both i686 and x86_64 using
the string benchtests.
On powerpc64 the gains are mixed, where only for larger inputs
or keys some gains are showns (based on benchtest it seems that
it shows some gains for keys larger than 10 and inputs larger
than 32). I would prefer to remove the optimized implementation
based on first code simplicity and second because some more gain
could be optimized using a better optimized strcspn/strspn
code (as for x86). However if powerpc arch maintainers prefer I
can send a v2 with the assembly code adjusted instead.
Checked on x86_64-linux-gnu, i686-linux-gnu, and powerpc64le-linux-gnu.

Consolidate arm and mips posix_fadvise implementations
As noted by c1f0601389db64d9, previous posix_fadvise consolidation
broke on mips o32. As stated in commit message, MIPS o32 only defines
__NR_fadvise64 and it is behaves like __NR_fadvise64_64.
This patches consolidates both ARM and mips o32 version by fixing
the ARM used option (__NR_fadvise64_64 withouth the alignment required
by abi) and added another option, __ASSUME_FADVISE64_AS_64_64,
which is used on mips o32.
When this option is used, posix_fadvise will use __NR_fadvise64_64
behavior (by defining or not __ASSUME_FADVISE64_64_6ARG). For
mips, if __NR_fadvise64_64 is not defined, __NR_fadvise will be used.
I also updated the posix_fadvise comments to explain better the
different kernel abi used in the supported architectures.
I checked with a mips o32 and verified that posix_fadvise.o is
indeed using 7 argument syscall with the expected argument position.
I also checked on i686-linux-gnu and arm-gnu-eabihf.
* sysdeps/unix/sysv/linux/arm/posix_fadvise.c: Remove file.

* sysdeps/unix/sysv/linux/posix_fadvise.c [__NR_fadvise64]: Add
!defined __ASSUME_FADVISE64_AS_64_64 to use syscall issue.
[!__NR_fadvise64 && __ASSUME_FADVISE64_64_6ARG]: Remove
__ALIGNMENT_ARG usage.
[!__NR_fadvise64 && !__ASSUME_FADVISE64_64_6ARG]: Define
__NR_fadvise64_64 if it is not defined.
