* Move math_opt_barrier, math_force_eval to separate math-barriers.h.Joseph Myers2018-05-0913-82/+245
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by this patch. * sysdeps/generic/math-barriers.h: New file. * sysdeps/generic/math_private.h [!math_opt_barrier] (math_opt_barrier): Move to math-barriers.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch continues cleaning up the math_private.h header, which contains lots of different definitions many of which are only needed by a limited subset of files using that header (and some of which are overridden by architectures that only want to override selected parts of the header), by moving the math_narrow_eval macro out to a separate math-narrow-eval.h header, only included by those files that need it. That header is placed in include/ (since it's used in stdlib/, not just files built in math/, but no sysdeps variants are needed at present). Tested for x86_64, and with build-many-glibcs.py. (Installed stripped shared libraries change because of line numbers in assertions in strtod_l.c.) * include/math-narrow-eval.h: New file.

* benchtests: Move iterator declaration into loop headerSiddhesh Poyarekar2018-05-073-6/+11
| | | | | | | | | | | This is a minor style change to move the definition of I to its usage scope instead of at the top of the function.

| | | | | | | | | | | | | | | | | | | | | | 2018-04-30 Raymond Nicholson <rain1@airmail.cc> * manual/startup.texi (Aborting a Program): Remove inappropriate joke. This complies with the decision of the project leader and primary and ultimate maintainer, who partially delegated maintainership to myself and others under certain constraints. This is also in line with the community-agreed procedures. It is obvious that we didn't have consensus on a decision to install that patch, since both sides are still arguing over it. As for the decision to reverse the deletion, if we even need one to counter a move that did not have consensus, although nobody else offered to install the reversal and restore the status prior to the fait accompli, and some explicitly refused to do so themselves, nobody objected when I offered to do so. Therefore, by the same reasoning that led to the mistaken installation of the patch, and after a much longer wait for objections, I understand there is consensus on my reverting it.

* Ignore absolute symbols in ABI tests.Joseph Myers2018-05-04327-1683/+357

With older binutils, it is included for MIPS o32 (despite the use of symbol versioning), and this means that all the ABI test baselines for MIPS o32 include "_gp_disp _gp_disp A". 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.

* Fix blocking pthread_join. [BZ #23137]Stefan Liebler2018-05-042-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Lu2018-05-028-8/+239
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Gomes2018-04-27116-60/+258
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Myers2018-04-27164-15720/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Consolidate getdirentries{64} implementationAdhemerval Zanella2018-04-255-20/+57
| | | | | | | | | | | | | | | | | | | | | | | This patch consolidates Linux getdirentries{64} implementation on just the default sysdeps/unix/sysv/linux/getdirentries{64} ones. The default implementation handles the Linux requirements: * getdirentries is only built for _DIRENT_MATCHES_DIRENT64 being 0. * getdirentries64 is always built and aliased to getdents for ABIs that define _DIRENT_MATCHES_DIRENT64 to 1. Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu, and powerpc64le-linux-gnu. * sysdeps/unix/sysv/linux/getdirentries.c (getdirentries): Build iff _DIRENT_MATCHES_DIRENT64 is not defined. * sysdeps/unix/sysv/linux/getdirentries64.c (getdirentries64): Open implementation and alias to getdirentries if _DIRENT_MATCHES_DIRENT64 is defined. * sysdeps/unix/sysv/linux/wordsize-64/getdirentries.c: Remove file. * sysdeps/unix/sysv/linux/wordsize-64/getdirentries64.c: Remove file.
* Use GCC 8 in build-many-glibcs.py by default.Joseph Myers2018-04-252-1/+6
| | | | | | | | | | | | | | | | | Now that GCC 8 has branched, this patch makes build-many-glibcs.py default to using GCC 8 branch instead of GCC 7. The effect should be that all builds complete cleanly and the compilation parts of the glibc testsuite complete cleanly except for on i686-gnu (with GCC 7 there were testsuite failures for some other configurations as well). I've replaced my bot building using GCC 6 branch with one using GCC 8 branch. (Of course glibc should continue building with GCC 6 - and for that matter GCC 5 and 4.9, which are no longer maintained, are supported versions as well - but building with GCC 6 will no longer be included in my bot testing.) * scripts/build-many-glibcs.py (Context.checkout): Default GCC version to GCC 8 branch.
* Fix Hurd glibc build with GCC 8.Joseph Myers2018-04-242-2/+8
| | | | | | | | | | | | | | | | | | | | 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.

* Add PTRACE_SECCOMP_GET_METADATA from Linux 4.16 to sys/ptrace.h.Joseph Myers2018-04-2411-8/+76

A type struct __ptrace_seccomp_metadata, analogous to other such types, is also added.

* Consolidate alphasort{64} and versionsort{64} implementationAdhemerval Zanella2018-04-2317-55/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch consolidates both alphasort{64} and versionsort{64} implementation on just the default dirent/alphasort{64}c and dirent/versionsort{64} respectively. It changes the logic to follow the conventions used on other code consolidation: * the non-LFS variant is only built for _DIRENT_MATCHES_DIRENT64 being 0. * the LFS variant is always built and aliased to getdents for ABIs that define _DIRENT_MATCHES_DIRENT64 to 1. Also on Linux the compat symbol for old non-LFS dirent64 definition requires a platform-specific scandir64.c. For powerpc32 and sparcv9 it requires to add specific arch-implementation to override the generic Linux one because neither ABI exports an compat symbol for non-LFS alphasort64 and versionsort64 variant. It is most likely a bug and it is also not one that can be fixed (in that there would be existing binaries expecting both meanings of that symbol at its single existing version, with binaries expecting the new meaning probably much more common than those expecting the original meaning of that symbol at that version). Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu, sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu, and powerpc64le-linux-gnu. * dirent/alphasort.c (alphasort): Build iff _DIRENT_MATCHES_DIRENT64 is defined. * dirent/versionsort.c (versionsort): Likewise. * dirent/alphasort64.c (alphasort64): Build regardless and alias to alphasort if _DIRENT_MATCHES_DIRENT64 is defined. * dirent/versionsort64.c (versionsort64): Likewise. * sysdeps/unix/sysv/linux/i386/alphasort64.c: Remove file. * sysdeps/unix/sysv/linux/arm/alphasort64.c: Likewise. * sysdeps/unix/sysv/linux/arm/versionsort64.c: Likewise. * sysdeps/unix/sysv/linux/m68k/alphasort64.c: Likewise. * sysdeps/unix/sysv/linux/m68k/versionsort64.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/alphasort64.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/versionsort64.c: Likewise. * sysdeps/unix/sysv/linux/i386/versionsort64.c: Likewise. * sysdeps/unix/sysv/linux/alphasort64.c: New file. * sysdeps/unix/sysv/linux/versionsort64.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/alphasort64.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/versionsort64.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/alphasort64.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/versionsort64.c: Likewise.
