* Don't write beyond destination in __mempcpy_avx512_no_vzeroupper (bug 23196)Andreas Schwab2018-05-231-2/+3
| | | | | When compiled as mempcpy, the return value is the end of the destination buffer, thus it cannot be used to refer to the start of it.
* Remove sysdeps/aarch64/soft-fp directory.Joseph Myers2018-05-225-4/+4
| | | | | | | | | | | | | | | | | | | | | | As per <https://sourceware.org/ml/libc-alpha/2014-10/msg00369.html>, there should not be separate sysdeps/<arch>/soft-fp directories when those are used by all configurations that use sysdeps/<arch>, and, more generally, should not be sysdeps/foo/Implies files pointing to a subdirectory foo/bar. This patch eliminates the sysdeps/aarch64/soft-fp directory accordingly, merging its contents into sysdeps/aarch64. Tested with build-many-glibcs.py that installed stripped shared libraries for aarch64 configurations are unchanged by this patch. * sysdeps/aarch64/Implies: Remove aarch64/soft-fp. * sysdeps/aarch64/Makefile [$(subdir) = math] (CPPFLAGS): Add -I../soft-fp. Moved from .... * sysdeps/aarch64/soft-fp/Makefile: ... here. Remove file. * sysdeps/aarch64/soft-fp/e_sqrtl.c: Move to .... * sysdeps/aarch64/e_sqrtl.c: ... here. * sysdeps/aarch64/soft-fp/sfp-machine.h: Move to .... * sysdeps/aarch64/sfp-machine.h: ... here.
* Fix i686-linux-gnu build with GCC mainline.Joseph Myers2018-05-222-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Building with recent GCC mainline for i686-linux-gnu is failing with: ../sysdeps/ieee754/flt-32/k_rem_pio2f.c: In function '__kernel_rem_pio2f': ../sysdeps/ieee754/flt-32/k_rem_pio2f.c:186:28: error: 'fq[0]' may be used uninitialized in this function [-Werror=maybe-uninitialized] fv = math_narrow_eval (fq[0]-fv); ^ and ../sysdeps/ieee754/dbl-64/k_rem_pio2.c: In function '__kernel_rem_pio2': ../sysdeps/ieee754/dbl-64/k_rem_pio2.c:333:32: error: 'fq[0]' may be used uninitialized in this function [-Werror=maybe-uninitialized] fv = math_narrow_eval (fq[0] - fv); ^ These are similar to -Warray-bounds cases for which the DIAG_* macros are already used in those files: the array element is in fact always initialized, but the reasoning that it is depends on another array not having been all zero at an earlier point, which depends on the functions not being called with zero arguments. Thus, this patch uses DIAG_* to disable -Wmaybe-uninitialized for this code. (The warning may be i686-specific because of math_narrow_eval somehow perturbing what the compiler does with this code enough to cause the warning. I don't know why it doesn't appear for i686-gnu.) Tested with build-many-glibcs.py that this fixes the i686 build in this configuration. * sysdeps/ieee754/dbl-64/k_rem_pio2.c (__kernel_rem_pio2): Ignore -Wmaybe-uninitialized around access to fq[0]. * sysdeps/ieee754/flt-32/k_rem_pio2f.c (__kernel_rem_pio2f): Likewise.
* Make llseek a compat symbol (bug 18471).Joseph Myers2018-05-224-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The llseek function name is an obsolete, Linux-specific, unprototyped name for lseek64 with a link-time warning. This patch completes the obsoletion of this function name by making it into a compat symbol, not available for newly linked programs and not included in the ABI for new ports. When a compat symbol is defined in syscalls.list, the code for that function is not built at all for static linking unless some non-compat symbol for that function is also defined with an explicit symbol version, so an explicit symbol version for lseek64 is added to the MIPS n32 syscalls.list. The case in make-syscalls.sh that handles such explicit non-compat symbol versions then needs to be changed to use weak_alias instead of strong_alias when the syscall is built outside of libc, to avoid linknamespace failures from a strong lseek64 symbol in static libpthread. The x32 llseek.S was as far as I could tell already unused (nothing builds an llseek.* source file, at least since the lseek / lseek64 / llseek consolidation), so is removed in this patch as well. Tested for x86_64 and x86, and with build-many-glibcs.py. [BZ #18471] * sysdeps/unix/make-syscalls.sh (emit_weak_aliases): Use weak aliases for non-libc case of versioned symbols. * sysdeps/unix/sysv/linux/lseek64.c: Include <shlib-compat.h>. (llseek): Define as compat symbol if [SHLIB_COMPAT (libc, GLIBC_2_0, GLIBC_2_28)], not as weak alias with link warning. * sysdeps/unix/sysv/linux/mips/mips64/n32/syscalls.list (llseek): Make into a compat symbol, disabled for minimum symbol version GLIBC_2.28 and later. * sysdeps/unix/sysv/linux/x86_64/x32/llseek.S: Remove file.
* i386: Drop -mpreferred-stack-boundary=4Florian Weimer2018-05-222-43/+1
| | | | | The flag was a left-over from when the -mpreferred-stack-boundary=2 flag was removed in commit db290cf59207aff09d1794e666e2854a93775f32.
* x86-64: Check Prefer_FSRM in ifunc-memmove.hH.J. Lu2018-05-213-1/+6
| | | | | | | | | | | | | Although the REP MOVSB implementations of memmove, memcpy and mempcpy aren't used by the current processors, this patch adds Prefer_FSRM check in ifunc-memmove.h so that they can be used in the future. * sysdeps/x86/cpu-features.h (bit_arch_Prefer_FSRM): New. (index_arch_Prefer_FSRM): Likewise. * sysdeps/x86/cpu-tunables.c (TUNABLE_CALLBACK (set_hwcaps)): Also check Prefer_FSRM. * sysdeps/x86_64/multiarch/ifunc-memmove.h (IFUNC_SELECTOR): Also return OPTIMIZE (erms) for Prefer_FSRM.
* Initial Fast Short REP MOVSB (FSRM) supportH.J. Lu2018-05-211-0/+3
| | | | | | | | | | The newer Intel processors support Fast Short REP MOVSB which has a feature bit in CPUID. This patch adds the Fast Short REP MOVSB (FSRM) bit to x86 cpu-features. * sysdeps/x86/cpu-features.h (bit_cpu_FSRM): New. (index_cpu_FSRM): Likewise. (reg_FSRM): Likewise.
* Obsolete nfsservctl.Joseph Myers2018-05-181-1/+1
| | | | | | | | | | | | | | | The Linux nfsservctl syscall was removed in Linux 3.1. Since the minimum kernel version for use with glibc is 3.2, the glibc wrapper for this syscall can no longer usefully be called. This patch makes it into a compat symbol, not provided at all for static linking or new ports. (It was already the case that there was no header declaration of this function.) Tested for x86_64. * sysdeps/unix/sysv/linux/syscalls.list (nfsservctl): Make into a compat symbol, disabled for minimum symbol version GLIBC_2.28 and later.
* x86-64: remove duplicate line on PREFETCH_ONE_SET macroLeonardo Sandoval2018-05-171-1/+0
| | | | | | | Tested on 64-bit AVX machine * sysdeps/x86_64/multiarch/memmove-vec-unaligned-erms.S (PREFETCH_ONE_SET): Remove duplicate line
* math: Reverse include order in <math-type-macros-*.h>Florian Weimer2018-05-174-4/+4
| | | | | | _Float128 is defined for certain compilers indirectly from <libm-alias-double.h>, and <ieee754_float128.h> (included from <math-nan-payload-float128.h>) needs this definition.
* nptl: Remove __ASSUME_PRIVATE_FUTEXH.J. Lu2018-05-1713-133/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since __ASSUME_PRIVATE_FUTEX is always defined, this patch removes the !__ASSUME_PRIVATE_FUTEX paths.

The changes are mostly essentially the same as for the other narrowing functions, so the description of those generally applies to this patch as well.

* Fix concurrent changes on nscd aware files (BZ #23178)Adhemerval Zanella2018-05-162-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As indicated by BZ#23178, concurrent access on some files read by nscd may result non expected data send through service requisition. This is due 'sendfile' Linux implementation where for sockets with zero-copy support, callers must ensure the transferred portions of the the file reffered by input file descriptor remain unmodified until the reader on the other end of socket has consumed the transferred data. I could not find any explicit documentation stating this behaviour on Linux kernel documentation. However man-pages sendfile entry [1] states in NOTES the aforementioned remark. It was initially pushed on man-pages with an explicit testcase [2] that shows changing the file used in 'sendfile' call prior the socket input data consumption results in previous data being lost. From commit message it stated on tested Linux version (3.15) only TCP socket showed this issues, however on recent kernels (4.4) I noticed the same behaviour for local sockets as well. Since sendfile on HURD is a read/write operation and the underlying issue on Linux, the straightforward fix is just remove sendfile use altogether. I am really skeptical it is hitting some hotstop (there are indication over internet that sendfile is helpfull only for large files, more than 10kb) here to justify that extra code complexity or to pursuit other possible fix (through memory or file locks for instance, which I am not sure it is doable). Checked on x86_64-linux-gnu. [BZ #23178] * nscd/nscd-client.h (sendfileall): Remove prototype. * nscd/connections.c [HAVE_SENDFILE] (sendfileall): Remove function.

| | | | | | | | | | | | | Unlike i386, we can call hidden IFUNC functions inside libc.so since x86-64 PLT is always PIC.

* Add narrowing multiply functions.Joseph Myers2018-05-1648-2/+842

The changes are mostly essentially the same as for the narrowing add functions, so the description of those generally applies to this patch as well. f32xmulf64 for i386 cannot use precision control as used for add and subtract, because that would result in double rounding for subnormal results, so that uses round-to-odd with long double intermediate result instead. The soft-fp support involves adding a new FP_TRUNC_COOKED since soft-fp multiplication uses cooked inputs and outputs.

* powerpc: Fix the compiler type used with C++ when -mabi=ieeelongdoubleTulio Magno Quites Machado Filho2018-05-111-10/+14
| | | | | | | | | | | | | | | | | | | | | | | | When compiling C++ code with -mabi=ieeelongdouble, KCtype is unavailable and the long double type should be used instead.

* aarch64,falkor: Ignore prefetcher tagging for smaller copiesSiddhesh Poyarekar2018-05-111-27/+41
| | | | | | | | | | | | | | | | | | For smaller and medium sized copies, the effect of hardware prefetching are not as dominant as instruction level parallelism. Hence it makes more sense to load data into multiple registers than to try and route them to the same prefetch unit. This is also the case for the loop exit where we are unable to latch on to the same prefetch unit anyway so it makes more sense to have data loaded in parallel. The performance results are a bit mixed with memcpy-random, with numbers jumping between -1% and +3%, i.e. the numbers don't seem repeatable. memcpy-walk sees a 70% improvement (i.e. > 2x) for 128 bytes and that improvement reduces down as the impact of the tail copy decreases in comparison to the loop. * sysdeps/aarch64/multiarch/memcpy_falkor.S (__memcpy_falkor): Use multiple registers to copy data in loop tail.
* aarch64,falkor: Ignore prefetcher hints for memmove tailSiddhesh Poyarekar2018-05-111-18/+28
| | | | | | | | | | | | | | | | | | The tail of the copy loops are unable to train the falkor hardware prefetcher because they load from a different base compared to the hot loop. In this case avoid serializing the instructions by loading them into different registers. Also peel the last iteration of the loop into the tail (and have them use different registers) since it gives better performance for medium sizes. This results in performance improvements of between 3% and 20% over the current falkor implementation for sizes between 128 bytes and 1K on the memmove-walk benchmark, thus mostly covering the regressions seen against the generic memmove. * sysdeps/aarch64/multiarch/memmove_falkor.S (__memmove_falkor): Use multiple registers to move data in loop tail.

* Move math_opt_barrier, math_force_eval to separate math-barriers.h.Joseph Myers2018-05-0912-82/+219
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch continues cleaning up math_private.h by moving the math_opt_barrier and math_force_eval macros to a separate header math-barriers.h. At present, those macros are inside a "#ifndef math_opt_barrier" in math_private.h to allow architectures to override them and then use a separate math-barriers.h header, no such #ifndef or #include_next is needed; architectures just have their own alternative version of math-barriers.h when providing their own optimized versions that avoid going through memory unnecessarily. The generic math-barriers.h has a comment added to document these two macros. In this patch, math_private.h is made to #include <math-barriers.h>, so files using these macros do not need updating yet. That is because of uses of math_force_eval in math_check_force_underflow and math_check_force_underflow_nonneg, which are still defined in math_private.h. Once those are moved out to a separate header, that separate header can be made to include <math-barriers.h>, as can the other files directly using these barrier macros, and then the include of <math-barriers.h> from math_private.h can be removed. Tested for x86_64 and x86.

This symbol is not meaningfully part of the ABI for shared libraries, since it always has to be resolved at static link time to the local definition for the linked object. All the other absolute symbols in ABI test baselines are the names of symbol versions. I don't think the mere existence of a symbol version with a given name - as opposed to the contents of that version if nonempty - is part of the ABI either. Thus, this patch allows the ABI tests to pass both before and after the binutils change by changing abilist.awk not to include absolute symbols in its output, and changing the baselines accordingly. Tested for x86_64, and with build-many-glibcs.py. * scripts/abilist.awk: Ignore absolute symbols. * sysdeps/mach/hurd/i386/ld.abilist: Remove absolute symbols. *

* Fix blocking pthread_join. [BZ #23137]Stefan Liebler2018-05-041-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On s390 (31bit) if glibc is build with -Os, pthread_join sometimes blocks indefinitely. This is e.g. observable with testcase intl/tst-gettext6. pthread_join is calling lll_wait_tid(tid), which performs the futex-wait syscall in a loop as long as tid != 0 (thread is alive). On s390 (and build with -Os), tid is loaded from memory before comparing against zero and then the tid is loaded a second time in order to pass it to the futex-wait-syscall. If the thread exits in between, then the futex-wait-syscall is called with the value zero and it waits until a futex-wake occurs. As the thread is already exited, there won't be a futex-wake. In lll_wait_tid, the tid is stored to the local variable __tid, which is then used as argument for the futex-wait-syscall. But unfortunately the compiler is allowed to reload the value from memory. With this patch, the tid is loaded with atomic_load_acquire. Then the compiler is not allowed to reload the value for __tid from memory. ChangeLog: [BZ #23137] * sysdeps/nptl/lowlevellock.h (lll_wait_tid): Use atomic_load_acquire to load __tid.

* x86: Use pad in pthread_unwind_buf to preserve shadow stack registerH.J. Lu2018-05-025-5/+206
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The pad array in struct pthread_unwind_buf is used by setjmp to save shadow stack register. We assert that size of struct pthread_unwind_buf is no less than offset of shadow stack pointer + shadow stack pointer size. Since functions, like LIBC_START_MAIN, START_THREAD_DEFN as well as these with thread cancellation, call setjmp, but never return after __libc_unwind_longjmp, __libc_unwind_longjmp, which is defined as __libc_longjmp on x86, doesn't need to restore shadow stack register. __libc_longjmp, which is a private interface for thread cancellation implementation in libpthread, is changed to call __longjmp_cancel, instead of __longjmp. __longjmp_cancel is a new internal function in libc, which is similar to __longjmp, but doesn't restore shadow stack register. The compatibility longjmp and siglongjmp in libpthread.so are changed to call __libc_siglongjmp, instead of __libc_longjmp, so that they will restore shadow stack register.

* powerpc64*: fix the order of implied sysdeps directoriesGabriel F. T. Gomes2018-04-27115-60/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The creation of the divergent sysdeps directory for powerpc64le commit 2f7f3cd8cd302bb10908c86f3f7b349df0a78e6a Author: Paul E. Murphy <murphyp@linux.vnet.ibm.com> Date: Fri Jul 15 18:04:40 2016 -0500 powerpc64le: Create divergent sysdep directory for powerpc64le. allowed float128 to be enabled for powerpc64le (little-endian) and not for powerpc64 (big-endian). Since the only intended difference between them was the presence or absence of the float128 interface, the sysdeps directory for powerpc64le explicitly reused the files from powerpc64 (through the use of Implies files). Although this works, it also means that files under the powerpc64 directory might be preferred over files under powerpc64le. For instance, on a build for powerpc64le with target set to power9, a file from powerpc64/power5 might get built, even though a file with the same name exists in powerpc64le/power8. That happens because the processor hierarchy was only defined in the sysdeps directory for powerpc64 (and borrowed by powerpc64le). This patch fixes this behavior, by creating new subdirectories under powerpc64 (i.e.: powerpc64/be and powerpc64/le) and creating new Implies files to provide the hierarchy of processors for powerpc64 and powerpc64le separately. These changes have no effect on installed, stripped binaries (which remain unchanged). Tested that installed stripped binaries are unchanged and that there are no regressions on powerpc64 and powerpc64le.
* Remove tilegx port.Joseph Myers2018-04-27159-15709/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since tile support has been removed from the Linux kernel for 4.17, this patch removes the (unmaintained) port to tilegx from glibc (the tilepro support having been previously removed). This reflects the general principle that a glibc port needs upstream support for the architecture in all the components it build-depends on (so binutils, GCC and the Linux kernel, for the normal case of a port supporting the Linux kernel but no other OS), in order to be maintainable. Apart from removal of sysdeps/tile and sysdeps/unix/sysv/linux/tile, there are updates to various comments referencing tile for which removal of those references seemed appropriate. The configuration is removed from README and from build-many-glibcs.py. contrib.texi keeps mention of removed contributions, but I updated Chris Metcalf's entry to reflect that he also contributed the non-removed support for the generic Linux kernel syscall interface. __ASSUME_FADVISE64_64_NO_ALIGN support is removed, as it was only used by tile. * sysdeps/tile: Remove. * sysdeps/unix/sysv/linux/tile: Likewise. * README (tilegx-*-linux-gnu): Remove from list of supported configurations. * manual/contrib.texi (Contributors): Mention Chris Metcalf's contribution of support for generic Linux kernel syscall interface. * scripts/build-many-glibcs.py (Context.add_all_configs): Remove tilegx configurations.

* Fix Hurd glibc build with GCC 8.Joseph Myers2018-04-241-2/+4
| | | | | | | | | | | | | | | | | | | | The build of glibc for Hurd has been failing with GCC mainline because of the checks that aliases have the same type as the symbol aliased; the Hurd dl-sysdep.c has a macro that defines aliases without using the proper type. When GCC 8 branches (soon), I intend to make it the default version in build-many-glibcs.py, so these failures would mean the default build-many-glibcs.py build fails for Hurd again. This patch fixes the Hurd build with GCC 8 by changing the macro that defines the problem aliases to use the correct type for them. An include of <not-errno.h> is needed to avoid this use of typeof resulting in an error for __access_noerrno not being declared. Tested compilation for i686-gnu with build-many-glibcs.py. * sysdeps/mach/hurd/dl-sysdep.c: Include <not-errno.h>. (check_no_hidden): Use type of original function when declaring alias.
