posix: Do not use WNOHANG in waitpid call for Linux posix_spawn
As shown in some buildbot issues on aarch64 and powerpc, calling clone (VFORK) and waitpid (WNOHANG) does not guarantee the child is ready to be collected. This patch changes the call back to 0 as before |

posix: Fix improper assert in Linux posix_spawn (BZ#22273)
As noted by Florian Weimer, current Linux posix_spawn implementation
can trigger an assert if the auxiliary process is terminated before
actually setting the err member:
340 /* Child must set args.err to something non-negative - we rely on
341 the parent and child sharing VM. */
342 args.err = -1;
[...]
362 new_pid = CLONE (__spawni_child, STACK (stack, stack_size), stack_size,
363 CLONE_VM | CLONE_VFORK | SIGCHLD, &args);
364
365 if (new_pid > 0)
366 {
367 ec = args.err;
368 assert (ec >= 0);
Another possible issue is killing the child between setting the err and
actually calling execve. In this case the process will not ran, but
posix_spawn also will not report any error:
269
270 args->err = 0;
271 args->exec (args->file, args->argv, args->envp);
As suggested by Andreas Schwab, this patch removes the faulty assert
and also handles any signal that happens before fork and execve as the
spawn was successful (and thus relaying the handling to the caller to
figure this out). Different than Florian, I can not see why using
atomics to set err would help here, essentially the code runs
sequentially (due CLONE_VFORK) and I think it would not be legal the
compiler evaluate ec without checking for new_pid result (thus there
is no need to compiler barrier).
Summarizing the possible scenarios on posix_spawn execution, we
have:
1. For default case with a success execution, args.err will be 0, pid
will not be collected and it will be reported to caller.
2. For default failure case, args.err will be positive and the it will
be collected by the waitpid. An error will be reported to the
caller.
3. For the unlikely case where the process was terminated and not
collected by a caller signal handler, it will be reported as succeful
execution and not be collected by posix_spawn (since args.err will
be 0). The caller will need to actually handle this case.
4. For the unlikely case where the process was terminated and collected
by caller we have 3 other possible scenarios:
4.1. The auxiliary process was terminated with args.err equal to 0:
it will handled as 1. (so it does not matter if we hit the pid
reuse race since we won't possible collect an unexpected
process).
4.2. The auxiliary process was terminated after execve (due a failure
in calling it) and before setting args.err to -1: it will also
be handle as 1. but with the issue of not be able to report the
caller a possible execve failures.
4.3. The auxiliary process was terminated after args.err is set to -1:
this is the case where it will be possible to hit the pid reuse
case where we will need to collected the auxiliary pid but we
can not be sure if it will be expected one. I think for this
case we need to actually change waitpid to use WNOHANG to avoid
hanging indefinitely on the call and report an error to caller
since we can't differentiate between a default failure as 2.
and a possible pid reuse race issue.
Checked on x86_64-linux-gnu.
* sysdeps/unix/sysv/linux/spawni.c (__spawnix): Handle the case where
the auxiliary process is terminated by a signal before calling _exit
or execve.

posix: Consolidate Linux glob implementation
This patch consolidates the glob implementation. The main changes are:
* On Linux all implementation now uses the default one at
sysdeps/unix/sysv/linux/glob{free}{64}.c with the exception
of alpha (which requires specific versioning) and s390-32 (which
different than other 32 bits ports it does not add a compat one
symbol for 2.1 version).
* The default implementation uses XSTAT_IS_XSTAT64 to define whether
both glob{free} and glob{free}64 should be different implementations.
For archictures that define XSTAT_IS_XSTAT64, glob{free} is an alias
to glob{free}64.
* Move i386 olddirent.h header to Linux default directory, since it is
the only header with this name and it is shared among different
architectures (and used on compat glob symbol as well).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.

posix: Sync glob with gnulib [BZ #1062]
This patch syncs posix/glob.c implementation with gnulib version
b5ec983 (glob: simplify symlink detection). The only difference
to gnulib code is
* DT_UNKNOWN, DT_DIR, and DT_LNK definition in the case there
were not already defined. Gnulib code which uses
HAVE_STRUCT_DIRENT_D_TYPE will redefine them wrongly because
GLIBC does not define HAVE_STRUCT_DIRENT_D_TYPE. Instead
the patch check for each definition instead.
Also, the patch requires additional globfree and globfree64 files
for compatibility version on some architectures. Also the code
simplification leads to not macro simplification (not need for
NO_GLOB_PATTERN_P anymore).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.

[NDEBUG): Remove comments.
(GLOB_ONLY_P, _AMIGA, VMS): Remove define.
(dirent_type): New type. Use uint_fast8_t not
uint8_t, as C99 does not require uint8_t.
(DT_UNKNOWN, DT_DIR, DT_LNK): New macros.
(struct readdir_result): Use dirent_type. Do not define skip_entry
unless it is needed; this saves a byte on platforms lacking d_ino.
(readdir_result_type, readdir_result_skip_entry):
New functions, replacing ...
(readdir_result_might_be_symlink, readdir_result_might_be_dir):
these functions, which were removed. This makes the callers
easier to read. All callers changed.
(D_INO_TO_RESULT): Now empty if there is no d_ino.
(size_add_wrapv, glob_use_alloca): New static functions.
(glob, glob_in_dir): Check for size_t overflow in several places,

(glob_in_dir): Remove old Amiga and VMS code.
(globfree, __glob_pattern_type, __glob_pattern_p): Move to
separate files.
(glob_in_dir): Do not rely on undefined behavior in accessing
struct members beyond their bounds. Use a flexible array member
instead

0/1. Caller changed.
(glob): Fix memory leaks.

aarch64: Optimized memcpy for Qualcomm Falkor processor
This is an optimized implementation of the memcpy routine that gives a significant gain in performance for all sizes of copies on the Qualcomm Falkor processor. A detailed rationale of the implementation is written in a comment in the patch. This implementation improves time for copies up to 128 bytes by up to 15% and for larger copies by up to 35% in the glibc microbenchmark. The memcpy-random benchmark sees improvements in all sizes in the range of 13%-18%. Here are the full numbers extracted from the glibc microbenchmark using the commands: ../benchtests/scripts/compare_strings.py benchtests/bench-memcpy.out \

posix: Set p{read,write}v2 to return ENOTSUP (BZ#21780)
Different than other architectures hppa-linux-gnu define different values
for ENOTSUP and EOPNOTSUPP, where the later is a Linux specific one.
This leads to tst-preadwritev{64}v2 tests failures:
$ ./testrun.sh misc/tst-preadvwritev2
error: tst-preadvwritev2-common.c:35: preadv2 failure did not set errno to ENOTSUP (223)
error: 1 test failures
The straightforward fix is to return the POSIX defined ENOTSUP on all
p{read,write}v{64}v2 implementations instead of Linux specific one.
Checked on x86_64-linux-gnu and the tst-preadwritev{64}v2 on
hppa-linux-gnu (although due the installed kernel on my testing system
the pwritev{64}v2 with an invalid flag still fails due a known kernel
issue [1]).

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. |

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. H.J.

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. |

SPARC sys/ucontext.h namespace fixes (bug 21457).

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.

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. * sysdeps/ia64/Implies: Add ieee754/float128. * sysdeps/ia64/bits/floatn.h: New file. * sysdeps/ia64/float128-abi.h: Likewise. * manual/math.texi (Mathematics): Document support for _Float128 on ia64. * sysdeps/ia64/Makefile [$(subdir) = math] (CPPFLAGS): Append to Makefile variable. * sysdeps/ia64/fpu/e_sqrtf128.c: New file. * sysdeps/ia64/fpu/k_rem_pio2.c: Remove file. * sysdeps/ia64/fpu/sfp-machine.h: New file.

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.) * sysdeps/i386/Implies: Add ieee754/float128. * sysdeps/x86_64/Implies: Likewise. * sysdeps/x86/bits/floatn.h: New file. * sysdeps/x86/float128-abi.h: Likewise. * manual/math.texi (Mathematics): Document support for _Float128 on x86_64 and x86. * sysdeps/i386/fpu/fenv_private.h: Include <bits/floatn.h>.

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).

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. [BZ #21622] * sysdeps/unix/sysv/linux/tile/bits/sigaction.h (SA_RESTART): Define for [__USE_UNIX98 || __USE_XOPEN2K8], not [__USE_UNIX98 || __USE_MISC]. (SA_NODEFER): Likewise.

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. * bits/signum.h: New file which just includes bits/signum-generic.h. * sysdeps/unix/bsd/bits/signum.h * sysdeps/unix/sysv/linux/bits/signum.h * sysdeps/unix/sysv/linux/alpha/bits/signum.h * sysdeps/unix/sysv/linux/hppa/bits/signum.h * sysdeps/unix/sysv/linux/mips/bits/signum.h * sysdeps/unix/sysv/linux/sparc/bits/signum.h Just include <bits/signum-generic.h> and then add or adjust signal constants. Do not define SIGUNUSED, SIGRTMIN, or SIGRTMAX. * signal/Makefile: Install bits/signum-generic.h. * signal/signal.h: Define SIGRTMIN and SIGRTMAX here. * sysdeps/generic/siglist.h: SIGSYS and SIGWINCH are universal. Prefer SIGPOLL to SIGIO. Simplify #ifdeffage. * sysdeps/unix/sysv/linux/tst-signal-numbers.sh: New test. * sysdeps/unix/sysv/linux/Makefile: Run it. |

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
for !__OFF_T_MATCHES_OFF64_T.
* sysdeps/unix/sysv/linux/openat64.c (__libc_openat64): New
implementation based on open64.
* sysdeps/unix/sysv/linux/wordsize-64/openat.c: Remove file.
* sysdeps/unix/sysv/linux/wordsize-64/openat64.c: Likewise.

conformtest: XFAIL uc_mcontext test for powerpc32 (bug 21635).
This patch XFAILs one test where the powerpc32 ucontext_t has the wrong type of a field, to allow the conform/ tests as a whole to pass once the namespace issues are fixed. Tested with build-many-glibcs.py. [BZ #21635] * sysdeps/unix/sysv/linux/powerpc/powerpc32/Makefile [$(subdir) = conform] (conformtest-xfail-conds): New variable. * conform/data/signal.h-data (uc_mcontext): XFAIL for powerpc32-linux. * conform/data/ucontext.h-data (uc_mcontext): Likewise. |

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. * elf/dl-tunables.list (tune): Add ifunc, x86_non_temporal_threshold, x86_data_cache_size and x86_shared_cache_size. * manual/tunables.texi: Document glibc.tune.ifunc, glibc.tune.x86_data_cache_size, glibc.tune.x86_shared_cache_size and glibc.tune.x86_non_temporal_threshold. * sysdeps/unix/sysv/linux/x86/dl-sysdep.c: New file. * sysdeps/x86/cpu-tunables.c: Likewise. * sysdeps/x86/cacheinfo.c (init_cacheinfo): Check and get data cache size, shared cache size and non temporal threshold from cpu_features. * sysdeps/x86/cpu-features.c [HAVE_TUNABLES] (TUNABLE_NAMESPACE): New. [HAVE_TUNABLES] Include <unistd.h>. [HAVE_TUNABLES] Include <elf/dl-tunables.h>. [HAVE_TUNABLES] (TUNABLE_CALLBACK (set_ifunc)): Likewise. [HAVE_TUNABLES] (init_cpu_features): Use TUNABLE_GET to set IFUNC selection, data cache size, shared cache size and non temporal threshold. * sysdeps/x86/cpu-features.h (cpu_features): Add data_cache_size, shared_cache_size and non_temporal_threshold. |
