This uses atomic operations to access lock elision metadata that is accessed
concurrently (ie, adapt_count fields). The size of the data is less than a
word but accessed only with atomic loads and stores; therefore, we add
support for shorter-size atomic load and stores too.
* include/atomic.h (__atomic_check_size_ls): New.
(atomic_load_relaxed, atomic_load_acquire, atomic_store_relaxed,
atomic_store_release): Use it.
* sysdeps/x86/elide.h (ACCESS_ONCE): Remove.
(elision_adapt, ELIDE_LOCK): Use atomics.
* sysdeps/unix/sysv/linux/x86/elision-lock.c (__lll_lock_elision): Use
atomics and improve code comments.
* sysdeps/unix/sysv/linux/x86/elision-trylock.c
(__lll_trylock_elision): Likewise.

TS 18661-1 defines llogb functions that are like ilogb except that
they return long int instead of int. Corresponding FP_LLOGB* macros
are defined, whose values are required to have the obvious
correspondence to those of the FP_ILOGB* macros.
This patch implements these functions and macros for glibc. llogb
uses the type-generic infrastructure, with an implementation similar
to the wrapper for ilogb but with additional conversion from FP_ILOGB*
to FP_LLOGB*; this approach avoids needing to modify or duplicate any
of the architecture-specific ilogb implementations. Tests are also
based on those for ilogb.
Ideally the llogb functions would alias the ilogb ones when long is
32-bit, but such aliasing requires the associated header declarations
of the different-type alias to be hidden, typically by defining macros
before including the header (see e.g. how
sysdeps/ieee754/dbl-64/wordsize-64/s_llround.c defines lround to
__hidden_lround before including <math.h>). The infrastructure for
type-generic function implementations does not support defining such
macros at present (since C code can't define a macro whose name is
determined by other macros). So this patch leaves them as separate
functions (similar to e.g. scalbln and scalbn being separate in such a
case as well), but with the remapping of FP_ILOGB* to FP_LLOGB*
conditioned out in the case where it would be the identity map.
Tested for x86_64, x86, mips64 and powerpc.

It is no longer needed since commit 6c444ad6e953dbdf9c7be065308a0a777
(elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]).
Applications do not link against ld.so and will use the definition in
libc.so, so there is no ABI impact.

This change moves the main implementation of _dl_catch_error,
_dl_signal_error to libc.so, where TLS variables can be used
directly. This removes a writable function pointer from the
rtld_global variable.
For use during initial relocation, minimal implementations of these
functions are provided in ld.so. These are eventually interposed
by the libc.so implementations. This is implemented by compiling
elf/dl-error-skeleton.c twice, via elf/dl-error.c and
elf/dl-error-minimal.c.
As a side effect of this change, the static version of dl-error.c
no longer includes support for the
_dl_signal_cerror/_dl_receive_error mechanism because it is only
used in ld.so.

The __longjmp symbol was left in accidentally. It is not exported
through a Versions file, but through a .symver assembler directive.
The corresponding exported symbol was removed from the non-fpu
powerpc64 targets in commit 9b9ef823581ecee546653d6ac3fd335f7b79faca.

Building tests for IA64 runs into a build failure compiling
stdlib/tst-setcontext2.c:
tst-setcontext2.c: In function 'do_test':
tst-setcontext2.c:210:20: error: passing argument 1 of 'sigismember' from incompatible pointer type [-Werror=incompatible-pointer-types]
if (sigismember (&oldctx.uc_sigmask, SIGUSR2) != 1)
^
Indeed, the IA64 uc_sigmask as unsigned long rather than the larger
userspace sigset_t. Fixing this might be hard; this patch works
around the build failure by making IA64 wrap the test with a version
that #defines sigismember to add a cast (I'd welcome a better approach
for fixing this).
Tested (compilation only) for ia64.
* sysdeps/unix/sysv/linux/ia64/tst-setcontext2.c: New file.

TS 18661-1 defines functions for manipulating the payloads of NaNs.
This patch implements the setpayloadsig functions for glibc; these are
like the setpayload functions, but produce a signaling NaN instead of
a quiet NaN.
The substance of the implementation was included with the setpayload
implementation, so the new files here just need to wrap the main files
with different defines to build the new functions.
Because the functions store a signaling NaN via a pointer and the
libm-test macros choose a suitable initial value for the variable in
such a case by comparing with the expected value, the relevant macro
needs to clear exceptions after FE_INVALID may have been raised by
that comparison.

This patch remove the PID cache and usage in current GLIBC code. Current
usage is mainly used a performance optimization to avoid the syscall,
however it adds some issues:
- The exposed clone syscall will try to set pid/tid to make the new
thread somewhat compatible with current GLIBC assumptions. This cause
a set of issue with new workloads and usecases (such as BZ#17214 and
[1]) as well for new internal usage of clone to optimize other algorithms
(such as clone plus CLONE_VM for posix_spawn, BZ#19957).
- The caching complexity also added some bugs in the past [2] [3] and
requires more effort of each port to handle such requirements (for
both clone and vfork implementation).
- Caching performance gain in mainly on getpid and some specific
code paths. The getpid performance leverage is questionable [4],
either by the idea of getpid being a hotspot as for the getpid
implementation itself (if it is indeed a justifiable hotspot a
vDSO symbol could let to a much more simpler solution).
Other usage is mainly for non usual code paths, such as pthread
cancellation signal and handling.
For thread creation (on stack allocation) the code simplification in fact
adds some performance gain due the no need of transverse the stack cache
and invalidate each element pid.
Other thread usages will require a direct getpid syscall, such as
cancellation/setxid signal, thread cancellation, thread fail path (at
create_thread), and thread signal (pthread_kill and pthread_sigqueue).
However these are hardly usual hotspots and I think adding a syscall is
justifiable.
It also simplifies both the clone and vfork arch-specific implementation.
And by review each fork implementation there are some discrepancies that
this patch also solves:
- microblaze clone/vfork does not set/reset the pid/tid field
- hppa uses the default vfork implementation that fallback to fork.
Since vfork is deprecated I do not think we should bother with it.
The patch also removes the TID caching in clone. My understanding for
such semantic is try provide some pthread usage after a user program
issue clone directly (as done by thread creation with CLONE_PARENT_SETTID
and pthread tid member). However, as stated before in multiple discussions
threads, GLIBC provides clone syscalls without further supporting all this
semantics.
I ran a full make check on x86_64, x32, i686, armhf, aarch64, and powerpc64le.
For sparc32, sparc64, and mips I ran the basic fork and vfork tests from
posix/ folder (on a qemu system). So it would require further testing
on alpha, hppa, ia64, m68k, nios2, s390, sh, and tile (I excluded microblaze
because it is already implementing the patch semantic regarding clone/vfork).

TS 18661-1 defines functions for manipulating the payloads of NaNs.
This patch implements the setpayload functions for glibc; these set a
number (pointed to by a function argument) to a quiet NaN with the
given payload, or to +0 if the given payload is not valid. The
implementations are structured to allow the substance of the
implementation to be shared with the setpayloadsig functions when
those are added.
The semantics in the TS are not entirely clear in the case where the
payload passed to the function is zero (see discussion on the WG14
reflector last month). This patch implements what seems the most
sensible interpretation, that -0 is never valid to give as the
payload, but +0 is valid in the case where the kind of NaN being
generated has its high mantissa bit set so payload 0 is actually
possible in such a NaN.

The set_dataplane() API in <sys/dataplane.h> originally supported the
Tilera version of Linux as shipped to our customers. Once we started
upstreaming the dataplane support in the kernel, the API changed
to use fcntl() as part of the current task-isolation patch series.
It doesn't seem like continuing to support the old API is useful
for newly-compiled code, and even supporting the old glibc binary
API on an upstream kernel that supports the new task isolation mode
isn't straightforward, since the semantics have changed in ways that
make it hard to map the old semantics precisely to the new ones,
so just return ENOSYS.

This patch consolidates all Linux setrlimit and getrlimit on the default
sysdeps/unix/sysv/linux/{set,get}rlimit{64}.c. It contains two exceptions:
1. mips32 and mips64n32 which requires a versioned symbol for GLIBC 2.19
and higher due a broken RLIM64_INFINITY constant.
2. sparc32 does not define a compat symbol for getrlimit64 for old 2GB
limit. I am not sure if it is required, but a RLIM_INFINITY fix [1]
change its definition without adding a compat symbol. This patch does
not aim to address this possible issue, it follow current symbol
export.
The default implementation uses prlimit64 for 64 bit rlim_t ({set,get}rlimit64)
and if it fails with ENOSYS it fall back to {get,set}rlimit syscall. This
code path is only used on kernel older than 2.6.36 (basically now only x86)
and I avoid to user __ASSUME_PRLIMTI64 to simplify the implementation. Once
x86 moves to be on par with other architectures regarding minimum kernel
supported we can get rid of using old syscalls and default path.
A new type size define is added, __RLIM_T_MATCHES_RLIM64_T, where is set as
default for 64 bits ports. This allows the default implementation to avoid
{get,set}rlimit building and alias {get,set}rlimit64 to {get,set}rlimit.
Checked on x86_64, i386, armhf, aarch64, and powerpc64le. I also did a
sanity build plus check-abi on all other supported architectures.

defines it. This patch fixes it by including <stddef.h>, as done for
other architectures' versions of this header.
Tested for Alpha (compilation only).

Implement an internal version of __access called __access_noerrno that
avoids setting errno. This is useful to check accessibility of files
very early on in process startup i.e. before TLS setup. This allows
tunables to replace MALLOC_CHECK_ safely (i.e. check existence of
/etc/suid-debug to enable/disable MALLOC_CHECK) and at the same time
initialize very early so that it can override IFUNCs.

As discussed in the thread starting at
<https://sourceware.org/ml/libc-alpha/2015-06/msg00657.html>, there
are various problems with the sigcontext / mcontext / ucontext
structures on SH. The soft-float SH4 case in fact does not build at
present, with errors processing
sysdeps/unix/sysv/linux/sh/sh4/ucontext_i.sym with gen-as-const.awk
("error: 'mcontext_t {aka struct <anonymous>}' has no member named
'fpregs'").
Linux 4.8 (commit bbe6c77857c38f4acbdc4fc70399515226d1859a) moved to
always using the same sigcontext structure on SH, with room for
floating-point registers whether or not present on the processor.
This patch makes the glibc header match.
Tested (compilation only) for sh4-linux-gnu hard float, and in
conjunction with other fixes for soft float.
* sysdeps/unix/sysv/linux/sh/sys/ucontext.h [__SH4__ || __SH4A__]:
Make code unconditional.
[!(__SH4__ || __SH4A__)]: Remove conditional code.

installed in lib directories.
Tested (compilation only) for tilegx (32-bit and 64-bit, BE and LE,
GCC 5).

The check-installed-headers tests show up that the SH <sys/user.h> is
not self-contained, using size_t without including any header that
defines it. This patch fixes it by including <stddef.h>, as done for
other architectures' versions of this header.
Tested for SH3 and SH4 (compilation only).
* sysdeps/unix/sysv/linux/sh/sys/user.h: Include <stddef.h>.

This patch consolidates all Linux truncate implementation on
sysdeps/unix/sysv/linux/truncate{64}.c. It is based on
{INTERNAL,INLINE}_SYSCALL patch [1] to simplify the syscall
construction.
General idea is to build ftruncate iff __OFF_T_MATCHES_OFF64_T is not
defined, otherwise ftruncate64 will be build and ftruncate will be an
alias. The fallocate will use old compat syscall and pass 32-bit off_t
argument, while fallocate64 will handle the correct off64_t passing using
__ALIGNMENT_ARG and SYSCALL_LL64 macros.
Tested on x86_64, i386, aarch64, and armhf.

This patch adds a localplt.data file for hppa so that test passes.
Architecture maintainers should feel free to clean up the sysdeps code
so that some or all of the system-specific entries
libc.so: _exit
libc.so: __sigsetjmp
libc.so: _IO_funlockfile
libc.so: sigprocmask
libc.so: __errno_location
libpthread.so: __errno_location
are no longer needed.
Tested for hppa. Note: check-execstack and check-textrel still fail;
you may wish to look at those to get to a clean baseline there (they
are less obvious for people not familiar with the architecture).

This patch updates alpha localplt.data so the localplt test passes in
my compile-only all-ABIs glibc testing. The failures I see without
this patch are:
Missing required PLT reference: ld.so: __tls_get_addr
Missing required PLT reference: ld.so: free
Now, __tls_get_addr can be made optional. For free, rather than
making it optional as in libc.so it seems better to mark all the
malloc-related symbols in both libc.so and ld.so as allowing an
R_ALPHA_GLOB_DAT relocation as an alternative to using a PLT entry, so
this patch does so.
Tested for alpha.
* sysdeps/unix/sysv/linux/alpha/localplt.data: Make __tls_get_addr
optional in ld.so. Allow R_ALPHA_GLOB_DAT relocation for malloc,
calloc, realloc, free, memalign and __libc_memalign rather than
making them optional.

This patch consolidates all Linux lseek/lseek64/llseek implementation
in on on sysdeps/unix/sysv/linux/lseek{64}.c. It also removes the llseek
file and instead consolidate the LFS lseek implementation on lseek64.c
as for other LFS symbols implementations.
The general idea is:
- lseek: ABIs that not define __OFF_T_MATCHES_OFF64_T will preferable
use __NR__llseek if kernel supports it, otherwise they will use __NR_lseek.
ABIs that defines __OFF_T_MATCHES_OFF64_T won't produce any symbol.
- lseek64: ABIs with __OFF_T_MATCHES_OFF64_T will preferable use __NR_lseek
(since it will use 64-bit arguments without low/high splitting) and
__NR__llseek if __NR_lseek is not defined (for some ILP32 ports).
- llseek: files will be removed and symbols will be aliased ot lseek64.
ABI without __OFF_T_MATCHES_OFF64_T and without __NR_llseek (basically MIPS64n32
so far) are covered by building lseek with off_t as expected and lseek64
using __NR_lseek (as expected for off64_t being passed using 64-bit registers).
For this consolidation I mantained the x32 assembly specific implementation
because to correctly fix this it would required both the x32 fix for
{INLINE,INTERNAL}_SYSCALL [1] and a wrapper to correctly subscribe it to
return 64 bits instead of default 32 bits (as for times). It could a future
cleanup.
It is based on my previous {INTERNAL,INLINE}_SYSCALL_CALL macro [2],
although it is mainly for simplification.

TS 18661-1 defines canonicalize functions to produce a canonical
version of a floating-point representation. This patch implements
these functions for glibc.
As with the iscanonical macro, these functions are oriented to the
decimal floating-point case, where some values have both canonical and
noncanonical representations. However, the functions have a return
value that says whether they succeeded in storing a canonical result;
thus, they can fail for the case of an invalid representation (while
still not making any particular choice from among multiple equally
canonical valid representations of the same value). Since no
floating-point formats in glibc actually have noncanonical valid
representations, a type-generic implementation of these functions can
be used that expects iscanonical to return 0 only for invalid
representations. Now that iscanonical is used within libm.so,
libm_hidden_proto / libm_hidden_def are added for __iscanonicall.
The definition of these functions is intended to correspond to a
convertFormat operation to the same floating-point format. Thus, they
convert signaling NaNs to quiet NaNs, raising the "invalid" exception.
Such a conversion "should" produce "the canonical version of that
signaling NaN made quiet".
libm-test.inc is made to check NaN payloads for the output of these
functions, a new feature (at some point manipulation functions such as
fabs and copysign should have tests added that verify payload
preservation for them). As however some architectures may not follow
the recommended practice of preserving NaN payloads when converting a
signaling NaN to quiet, a new math-tests.h macro
SNAN_TESTS_PRESERVE_PAYLOAD is added, and defined to 0 for non-NAN2008
MIPS; any other architectures seeing test failures for lack of payload
preservation in this case should also define this macro to 0. (If any
cases arise where the sign isn't preserved either, those should have a
similar macro added.)
The ldbl-96 and ldbl-128ibm tests of iscanonical are renamed and
adapted to test canonicalizel as well on the same representations.

ISO/IEC TS 18661-1 adds several functions in the strfrom family to stdlib.
This patch adds strfromd, strfromf, and strfroml. This is being done in
preparation for the new floating-point type, float128. The added functions
convert a floating-point value into a string, with configurable format.

Although conceptually correct for p{read,write}{64} offset argument passing,
sh4 implementation does not generate the correct expected code. The
__ALIGNMENT_ARG redefinition is incorrect for two reasons: 1. the
kernel-features.h header is included multiple times (since it contains no
guards) and 2. the value it redefines is also incorrect (should be '0, '
instead of empty definition).
This patch fixes it by adding another macro, SYSCALL_LL_PRW{64}, meant to be
used to pass the offset argument on p{read,write}64. It is basically the
already define SYSCALL_LL{64} plus __ALIGNMENT_ARG unless __ASSUME_PRW_DUMMY_ARG
is define. In this case an empty dummy argument is used regardless how
__ALIGNMENT_ARG is defined (sh4 case).
Checked on x86_64, i686, aarch64, armhf, and powerpc64le (basically a sanity
check). Also, John Paul Adrian Glaubitz <glaubitz@physik.fu-berlin.de> and
James Clarke <jrtc27@jrtc27.com> help me check on a debian sh4 bootstrap using
2.24 plus this patch to verify it also corrected fixed the regression issue.
I also verified the generated object for a 2.24 build and master with this
patch for sh4 and both look identical.

TS 18661-1 defines functions for manipulating the payloads of NaNs.
This patch implements the getpayload functions for glibc; these
extract the NaN payload (from an argument passed as a pointer, for
which corresponding libm-test support is added) and return it in the
same floating-point type. The return value of these functions is
unspecified for non-NaN arguments; the patch does the simplest thing
to implement, which is that the functions do not check whether the
argument is a NaN and just treat the relevant bits of the
representation as a payload regardless. A conversion from integer to
floating-point is used to produce the required return value, except in
the ldbl-128 case; as 128-bit integers are not supported for all
configurations using ldbl-128, the code constructs the required
floating-point representation of the return value directly instead.
Tested for x86_64, x86, mips64 and powerpc.

The fallocate syscall might fail on Linux due missing support from
underlying filesystem (for instance some NFS versions). This patch
adds this check for fallocate tests. It also moves tst-fallocate{64}
to 'io' folder (since it is on fallocate{64} is built).
Checked on x86_64.
* sysdeps/unix/sysv/linux/Makefile [$(subdir) = math] (tests): Move
tst-fallocate{64}.
* sysdeps/unix/sysv/linux/tst-fallocate-common.c: Check for EOPNOTSUPP
on syscall return.
