2018-04-24Fix tst-strfmon_l test for hr_HR localeMike FABIAN
The test needs to be adapted for the change in the thousands separators: “hr_HR locale: fix thousands_sep and mon_thousands_sep” [BZ #23094]
2018-04-24Add PTRACE_SECCOMP_GET_METADATA from Linux 4.16 to sys/ptrace.h.Joseph Myers
This patch adds the PTRACE_SECCOMP_GET_METADATA constant from Linux 4.16 to all relevant sys/ptrace.h files. A type struct __ptrace_seccomp_metadata, analogous to other such types, is also added. Tested for x86_64, and with build-many-glibcs.py. * sysdeps/unix/sysv/linux/sys/ptrace.h (PTRACE_SECCOMP_GET_METADATA): New enum value and macro. * sysdeps/unix/sysv/linux/bits/ptrace-shared.h (struct __ptrace_seccomp_metadata): New type. * sysdeps/unix/sysv/linux/aarch64/sys/ptrace.h (PTRACE_SECCOMP_GET_METADATA): Likewise. * sysdeps/unix/sysv/linux/arm/sys/ptrace.h (PTRACE_SECCOMP_GET_METADATA): Likewise. * sysdeps/unix/sysv/linux/ia64/sys/ptrace.h (PTRACE_SECCOMP_GET_METADATA): Likewise. * sysdeps/unix/sysv/linux/powerpc/sys/ptrace.h (PTRACE_SECCOMP_GET_METADATA): Likewise. * sysdeps/unix/sysv/linux/s390/sys/ptrace.h (PTRACE_SECCOMP_GET_METADATA): Likewise. * sysdeps/unix/sysv/linux/sparc/sys/ptrace.h (PTRACE_SECCOMP_GET_METADATA): Likewise. * sysdeps/unix/sysv/linux/tile/sys/ptrace.h (PTRACE_SECCOMP_GET_METADATA): Likewise. * sysdeps/unix/sysv/linux/x86/sys/ptrace.h (PTRACE_SECCOMP_GET_METADATA): Likewise.
2018-04-23Consolidate alphasort{64} and versionsort{64} implementationAdhemerval Zanella
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.

2018-04-19Consolidate Linux getdents{64} implementationAdhemerval Zanella
This patch consolidates Linux getdents{64} implementation on just the default sysdeps/unix/sysv/linux/getdents{64}{_r}.c ones. Although this symbol is used only internally, the non-LFS version still need to be build due the non-LFS getdirentries which requires its semantic. The non-LFS default implementation now uses the wordsize-32 as base which uses getdents64 syscall plus adjustment for overflow (it allows to use the same code for architectures that does not support non-LFS getdents syscall). It has two main differences to wordsize-32 one: - DIRENT_SET_DP_INO is added to handle alpha requirement to zero the padding. - alloca is removed by allocating a bounded temporary buffer (it increases stack usage by roughly 276 bytes). The default implementation handle the Linux requirements: * getdents is only built for _DIRENT_MATCHES_DIRENT64 being 0. * getdents64 is always built and aliased to getdents for ABIs that define _DIRENT_MATCHES_DIRENT64 to 1. * A compat symbol is added for getdents64 for ABI that used to export the old non-LFS 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. * sysdeps/unix/sysv/linux/alpha/getdents.c: Add comments with alpha requirements.

2018-04-19Disable lock elision for mutex pretty printer tests.Stefan Liebler
If e.g. the testcase nptl/test-mutex-printers is run with enabled lock-elision, it fails on s390x with: Error: Response does not match the expected pattern. Command: print *mutex Expected pattern: pthread_mutex_t Response: No symbol "mutex" in current context. (gdb) See https://www.sourceware.org/ml/libc-alpha/2018-03/msg00583.html for more details. In fact the mutex pretty printer tests rely on looking at the internal details of the lock, thus we disable it by setting up the GLIB_TUNABLES environment variable inside gdb. ChangeLog: * scripts/test_printers_common.py (init_test): Disable lock elision.
2018-04-19Use volatile global counters in test-tgmath.c.Stefan Liebler
If build with -Os on s390x, the test-tgmath fails with: float functions not called often enough (-10000) Within compile_testf(), the counter (count_float) is saved before the complex functions are called. Afterwards the saved counter differs to the current-counter. But the tests with the complex functions do not increment count_float! Instead count_float is saved to a register before calling totalorder and totalordermag which both increment count_float. The compiler is allowed to do that as totalorderf and totalordermagf is declared with __attribute__ ((__const__)) in math/bits/mathcalls.h. Thus this patch adjusts the global counters to be volatile. Then count_float is saved after totalordermag. ChangeLog: * math/test-tgmath.c (count_double, count_float, count_ldouble, count_cdouble, count_cfloat, count_cldouble): Use volatile int.
2018-04-19hurd: Update struct statfs according to struct statvfsSamuel Thibault
* sysdeps/mach/hurd/bits/statfs.h (struct statfs): Make f_bsize, f_namemax, f_frsize, and f_flag fields unsigned long int instead of unsigned int. (struct statfs64): Likewise.
2018-04-19hurd: Fix standard compliance of some statvfs fieldsSamuel Thibault
Standards require that the f_bsize, f_frsize, f_flag and f_namemax fields be unsigned long. They used to be only unsigned on hurd, which happens to be compatible with unsigned long on the only existing, 32bit, port. We can thus merely fix the type. * sysdeps/mach/hurd/bits/statvfs.h (struct statvfs): Make f_bsize, f_namemax, f_frsize, and f_flag fields unsigned long int instead of unsigned int. (struct statvfs64): Likewise.

2018-04-18Make build-many-glibcs.py build GCC for powerpcspe with --enable-obsolete.Joseph Myers
The powerpcspe GCC port has been obsoleted in GCC 8 for not having had the removal of code for non-SPE processors completed. This patch accordingly arranges for build-many-glibcs.py to configure GCC with --enable-obsolete for affected configurations. This is temporary; either the port gets cleaned up and unobsoleted in GCC and the configure option can be removed, or the port gets removed in GCC and we should remove the corresponding glibc support. Tested with build-many-glibcs.py for the affected configurations. * scripts/build-many-glibcs.py (Context.add_all_configs): Use --enable-obsolete for powerpc-linux-gnuspe.

2018-04-16arm: Remove ununsed ARM code in optimized implementationAdhemerval Zanella
This patch removes the ununsed ARM code path for armv6t2 memchr and strlen and armv7 memch and strcmp. In all implementation, the ARM code is not used in any possible build (unless glibc is explicit build with the non-documented NO_THUMB compiler flag) and for armv7 the resulting code either produces wrong results (memchr) and throw build error (strcmp). Checked on arm-linux-gnueabihf built targeting both armv6 and armv7. * sysdeps/arm/armv6t2/memchr.S (memchr): Remove ARM code path. * sysdeps/arm/armv6t2/strlen.S (memchr): Likewise. * sysdeps/arm/armv7/multiarch/memchr_neon.S (memchr): Likewise. * sysdeps/arm/armv7/strcmp.S (strcmp): Likewise.

Adds a fast path to e_exp.c when |x| < 1.03972053527832. When values are tested in isolation, reduction in execution time is: aarch 30%, sparc 18%, x86 37%. When comparing benchtests/bench.out which includes values outside that range, the gains are: aarch 8%, sparc 5%, x86 9%. make check is clean (no increase in ulp for any math test). Testing 20M values for each rounding mode in that range shows approximately one in 200 values is off by 1 ulp. No value tested for exp(x) changed by 2 or more ulp. No observed change in performance or accuracy for x outside fast path range. These changes will be active for all platforms that don't provide their own exp() routines. They will also be active for ieee754 versions of ccos, ccosh, cosh, csin, csinh, sinh, exp10, gamma, and erf.
2018-04-12Update kernel version in syscall-names.list to 4.16.DJ Delorie
Linux 4.16 does not add any new syscalls; this patch updates the version number in syscall-names.list to reflect that it's still current for 4.16. Tested for x86_64 (compilation with build-many-glibcs.py, using Linux 4.16). * sysdeps/unix/sysv/linux/syscall-names.list: Update kernel version to 4.16.
2018-04-12S390: Fix struct sigaction for 31bit in kernel_sigaction.h.Stefan Liebler
The recent commit b4a5d26d8835d972995f0a0a2f805a8845bafa0b "linux: Consolidate sigaction implementation" changed the definition of struct sigaction for s390 (31bit). Unfortunately the order of the fields were wrong. This leads to blocking testcases e.g. nptl/tst-sem11. A thread which blocks due to sem_wait() is cancelled via pthread_cancel() and the signal-handler sigcancel_handler (see <glibc-src>/nptl/nptl-init.c is called. But it just returns as the siginfo_t argument is not setup by the kernel. Then the main-thread is blocking due to pthread_join(). The flag SA_SIGINFO is set in sa_flags in struct sigaction and is copied to the "kernel_sigaction.h" struct by the sigaction() call, but due to the wrong ordering of the struct fields, the kernel does not recognize it.

2018-04-06Consolidate Linux readdir{64}{_r} implementationAdhemerval Zanella
This patch consolidates Linux readdir{64}{_r} implementation on just the default sysdeps/unix/sysv/linux/readdir{64}{_r}.c ones. The default implementation handle the Linux requirements: * readdir{_r} is only built for _DIRENT_MATCHES_DIRENT64 being 0. * readdir64{_r} is always built and aliased to readdir{_r} for ABI that define _DIRENT_MATCHES_DIRENT64. * A compat symbol is added for readdir64{_r} for ABI that used to export the old non-LFS 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. * sysdeps/posix/readdir.c (__READDIR, __GETDENTS, DIRENTY_TYPE, __READDIR_ALIAS): Undefine after usage. * sysdeps/posix/readdir_r.c (__READDIR_R, __GETDENTS, DIRENT_TYPE, __READDIR_R_ALIAS): Likewise. * sysdeps/unix/sysv/linux/arm/readdir64.c: Remove file. * sysdeps/unix/sysv/linux/arm/readdir64_r.c: Likewise. * sysdeps/unix/sysv/linux/m68k/readdir64.c: Likewise. * sysdeps/unix/sysv/linux/m68k/readdir64_r.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/readdir64.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/readdir64_r.c: Likewise. * sysdeps/unix/sysv/linux/i386/readdir64.c: Likewise. * sysdeps/unix/sysv/linux/i386/readdir64_r.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/readdir64.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/readdir64_r.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/readdir64.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/readdir64_r.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/readdir.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/readdir64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/readdir64_r.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/readdir_r.c: Likewise. * sysdeps/unix/sysv/linux/readdir.c: New file. * sysdeps/unix/sysv/linux/readdir_r.c: Likewise. * sysdeps/unix/sysv/linux/readdir64.c: Add compat symbol if required. * sysdeps/unix/sysv/linux/readdir64_r.c: Likewise.

2018-04-05linux: Consolidate sigaction implementationAdhemerval Zanella
This patch consolidates all Linux sigaction implementations on the default sysdeps/unix/sysv/linux/sigaction.c. The idea is remove redundant code and simplify new ports addition by following the current generic Linux User API (UAPI). The UAPI for new ports defines a generic extensible sigaction struct as: struct sigaction { __sighandler_t sa_handler; unsigned long sa_flags; #ifdef SA_RESTORER void (*sa_restorer) (void); #endif sigset_t sa_mask; }; Where SA_RESTORER is just placed for compatibility reasons (news ports should not add it). A similar definition is used on generic kernel_sigaction.h. The user exported sigaction definition is not changed, so for most architectures it requires an adjustment to kernel expected one for the syscall. The main changes are: - All architectures now define and use a kernel_sigaction struct meant for the syscall, even for the architectures where the user sigaction has the same layout of the kernel expected one (s390-64 and ia64). Although it requires more work for these architectures, it simplifies the generic implementation. Also, sigaction is hardly a hotspot where micro optimization would play an important role. - The generic kernel_sigaction definition is now aligned with expected UAPI one for newer ports, where SA_RESTORER and sa_restorer are not expected to be defined. This means adding kernel_sigaction for current architectures that does define it (m68k, nios2, powerpc, s390, sh, sparc, and tile) and which rely on previous generic definition. - Remove old MIPS usage of sa_restorer. This was removed since 2.6.27 (2957c9e61ee9c - "[MIPS] IRIX: Goodbye and thanks for all the fish"). - The remaining arch-specific sigaction.c are to handle ABI idiosyncrasies (like SPARC kernel ABI for rt_sigaction that requires an additional stub argument). So for new ports the generic implementation should work if its uses Linux UAPI. If SA_RESTORER is still required (due some architecture limitation), it should define its own kernel_sigaction.h, define it and include generic header (assuming it still uses the default generic kernel layout). Checked on x86_64-linux-gnu, i686-linux-gnu, arm-linux-gnueabihf, aarch64-linux-gnu, sparc64-linux-gnu, sparcv9-linux-gnu, powerpc-linux-gnu, powerpc64-linux-gnu, ia64-linux-gnu and alpha-linux-gnu.
