2017-09-12x86: Add MathVec_Prefer_No_AVX512 to cpu-features [BZ #21967]H.J. Lu4-5/+29
AVX512 functions in mathvec are used on machines with AVX512. An AVX2 wrapper is also provided and it can be used when the AVX512 version isn't profitable. MathVec_Prefer_No_AVX512 is addded to cpu-features. If glibc.tune.hwcaps=MathVec_Prefer_No_AVX512 is set in GLIBC_TUNABLES environment variable, the AVX2 wrapper will be used. Tested on x86-64 machines with and without AVX512. Also verified glibc.tune.hwcaps=MathVec_Prefer_No_AVX512 on AVX512 machine. [BZ #21967] * sysdeps/x86/cpu-features.h (bit_arch_MathVec_Prefer_No_AVX512): New. (index_arch_MathVec_Prefer_No_AVX512): Likewise. * sysdeps/x86/cpu-tunables.c (TUNABLE_CALLBACK (set_hwcaps)): Handle MathVec_Prefer_No_AVX512. * sysdeps/x86_64/fpu/multiarch/ifunc-mathvec-avx512.h (IFUNC_SELECTOR): Return AVX2 version if MathVec_Prefer_No_AVX512 is set.

2017-09-11Define and use a libm_alias_float macro.Joseph Myers3-0/+48
Fully supporting TS 18661-3 _FloatN / _FloatNx types in the cases where they have the same format as other supported types (in line with the principles described at <https://sourceware.org/ml/libc-alpha/2017-01/msg00333.html>) means adding a lot of function aliases to libm (and a few to libc). float functions will have *f32 aliases, double functions will have *f32x and *f64 aliases, long double functions may have *f64x, *f128 or both aliases depending on the configuration, float128 functions have have *f64x aliases depending on the configuration. At present, most individual libm functions have their own weak_alias calls to define the public names for those functions. For TS 18661-3 support, it is desirable that functions not all need to duplicate the logic for which alias names to define. Thus, common macros for defining the public aliases to a libm function make sense. In the double and long double cases, such macros will also help simplify existing code (with LONG_DOUBLE_COMPAT etc. conditionals), by eliminating existing conditionals and ldbl-opt / ldbl-64-128 wrappers (using the generated ldbl-compat-choose.h to allow a single macro definition to expand appropriately for each symbol depending on LONG_DOUBLE_COMPAT for that symbol). This patch starts the process of adding such macros with a straightforward case: a libm_alias_float macro, initially only used in the case of type-generic templates, to define aliases for float functions (currently just the *f public names, in future also *f32). Future patches are intended to add such macros for other types and to extend the cases in which they are used, with a view to as many places as possible using them before support for _FloatN / _FloatNx aliases is enabled. (I think it's inevitable that some places doing architecture-specific things with aliases and symbol versioning may end up needing to replicate logic for the new aliases, but hopefully the number of such places can be kept to a minimum.) The libm_alias_float macro takes unsuffixed names for both the internal and public function names. The need for unsuffixed public names is obvious, since such macros will end up defining multiple public names with different suffixes. Unsuffixed internal names are because I expect the ldbl-128 functions to end up in a form that always defines *f128 names and sometimes also defines *l names - with the main internal names being e.g. __ieee754_<func>f128 (so many macros in float128_private.h can go away). But __ieee754_<func>l aliases will still be needed for e.g. use from math/ complex functions, meaning the alias macro needs to see just __ieee754_<func> as internal name so it can create an alias based on that name. Since libm_alias_float128 will thus need the unsuffixed internal name, it seems to make sense for all such macros to receive the unsuffixed name. Tested for x86_64. Also tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * sysdeps/generic/libm-alias-float.h: New file. * sysdeps/generic/math-type-macros-float.h: Include <libm-alias-float.h>. [!declare_mgen_alias] (declare_mgen_alias): Define macro.
2017-09-11x86: Add x86_64 to x86-64 HWCAP [BZ #22093]H.J. Lu7-8/+95
Before glibc 2.26, ld.so set dl_platform to "x86_64" and searched the "x86_64" subdirectory when loading a shared library. ld.so in glibc 2.26 was changed to set dl_platform to "haswell" or "xeon_phi", based on supported ISAs. This led to shared library loading failure for shared libraries placed under the "x86_64" subdirectory. This patch adds "x86_64" to x86-64 dl_hwcap so that ld.so will always search the "x86_64" subdirectory when loading a shared library. NB: We can't set x86-64 dl_platform to "x86-64" since ld.so will skip the "haswell" and "xeon_phi" subdirectories on "haswell" and "xeon_phi" machines. Tested on i686 and x86-64. [BZ #22093] * sysdeps/x86/cpu-features.c (init_cpu_features): Initialize GLRO(dl_hwcap) to HWCAP_X86_64 for x86-64. * sysdeps/x86/dl-hwcap.h (HWCAP_COUNT): Updated. (HWCAP_IMPORTANT): Likewise.

2017-09-08Add fcntl sealing interfaces from Linux 3.17 to bits/fcntl-linux.h.Joseph Myers2-0/+20
While reviewing Linux 4.13 for glibc header changes needed, I noticed that bits/fcntl-linux.h was missing F_ADD_SEALS etc. from Linux 3.17. I didn't find any discussion indicating this omission is deliberate. Now, these interfaces can only be used with file descriptors created with memfd_create, and we don't have a memfd_create wrapper in glibc (a patch was submitted in October 2014, albeit without documentation / tests, and discussions continued over the next few months, but without consensus on whether to add the interface - and we still lack any general consensus on syscall wrappers), but I don't think that's a reason to exclude the constants from bits/fcntl-linux.h (especially as the header does not look compatible with simultaneously including linux/fcntl.h). (Some of those 2014/2015 discussions raised concerns about difficulty using the memfd_create / sealing interface, but those seem to me more like a question of whether it should be part of the OS-independent GNU API - in my view, even fairly specialized syscalls ought to have wrappers added to glibc if not obsolescent, but there may be cases where we only want to include them in the Linux-specific API and anything in the OS-independent GNU API should be different - rather than being relevant to whether constants for use with fcntl should appear in headers.) * sysdeps/unix/sysv/linux/bits/fcntl-linux.h [__USE_GNU] (F_ADD_SEALS): New macro.

2017-09-08posix: Consolidate Linux glob implementationAdhemerval Zanella27-48/+160
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. * sysdeps/unix/sysv/linux/arm/glob64.c: Remove file. * sysdeps/unix/sysv/linux/i386/glob64.c: Likewise. * sysdeps/unix/sysv/linux/m68k/glob64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/glob64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/globfree64.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/glob64.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/glob64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/glob64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/globfree64.c: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/glob.c: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/globfree.c: Likewise. * sysdeps/wordsize-64/glob.c: Likewise. * sysdeps/wordsize-64/glob64.c: Likewise. * sysdeps/wordsize-64/globfree64.c: Likewise. * sysdeps/unix/sysv/linux/glob.c: New file. * sysdeps/unix/sysv/linux/glob64.c: Likewise. * sysdeps/unix/sysv/linux/globfree.c: Likewise. * sysdeps/unix/sysv/linux/globfree64.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/glob64.c: Likewise. * sysdeps/unix/sysv/linux/oldglob.c [SHLIB_COMPAT]: Also adds !GLOB_NO_OLD_VERSION as an extra condition. * sysdeps/unix/sysv/linux/i386/alphasort64.c: Include olddirent.h using relative path instead of absolute one. * sysdeps/unix/sysv/linux/i386/getdents64.c: Likewise. * sysdeps/unix/sysv/linux/i386/readdir64.c: Likewise. * sysdeps/unix/sysv/linux/i386/readdir64_r.c: Likewise. * sysdeps/unix/sysv/linux/i386/versionsort64.c: Likewise. * sysdeps/unix/sysv/linux/i386/olddirent.h: Move to ... * sysdeps/unix/sysv/linux//olddirent.h: ... here.
2017-09-08posix: fix glob bugs with long login namesAdhemerval Zanella2-58/+37
Current glob implementation allows unlimited user name for home directory construction on GLOB_TILDE case. To accomplish it glob either construct a name on stack if size are small enough (based on current alloca_used) or in heap otherwise. This patch simplifies storage allocation by using the same scratch buffer for both get_rlogin_r and getpwnam_r. This also syncs with gnulib commit 064df0b (glob: fix bugs with long login names). Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures. * posix/glob.c (GET_LOGIN_NAME_MAX): Remove. (glob): Use the same scratch buffer for both getlogin_r and getpwnam_r. Don’t require preallocation of the login name. This simplifies storage allocation, and corrects the handling of long login names.

This patch fixes longstanding misuse of errno after getpwnam_r, which returns an error number rather than setting errno. This is sync with gnulib commit 5db9301. Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures. [BZ #1062] * posix/glob.c (glob): Port recent patches to platforms lacking getpwnam_r.

Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures. * include/scratch_buffer.h (scratch_buffer): Use a C99 align method instead of GCC extension. * malloc/scratch_buffer_grow.c [!_LIBC]: Include libc-config.h. * malloc/scratch_buffer_grow_preserve.c [!_LIBC]: Likewise. * malloc/scratch_buffer_set_array_size.c [!_LIBC]: Likewise.
2017-09-08posix: Allow glob to match dangling symlinks [BZ #866]Adhemerval Zanella5-243/+233
This patch makes glob match dangling symlinks. Compared to other glob implementation (*BSD, bash, musl, and other shells as well), GLIBC seems the be the only one that does not match dangling symlinks. As for comment #5 in BZ #866, POSIX does not have any strict specification for dangling symlinks match and it is reasonable that trying to glob everything in a path should return all types of files (such as for a 'rm *'). Also, comment #7 shows even more example where GLIBC current behavior is unexepected. I avoided adding another GNU specific flag to set this behavior and instead make it the default. Although this change the semanthic from previous implementation, I think adding another compat symbol to be really unecessary as from aforementioned reasons (current behavior not defined in any standard, general idea of different implementation is to list dangling symbols). This also sync glob with gnulib commit fd1daf4 (glob: match dangling symlinks). Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures. [BZ #866] [BZ #1062] * posix/Makefile (tests): Remove bug-glob1 and tst-glob_symlinks. * posix/bug-glob1.c: Remove file. * posix/tst-glob_symlinks.c: New file. * posix/glob.c (__lstat64): New macro.

2017-09-08posix: accept inode 0 is a valid inode number (BZ #19971)Adhemerval Zanella2-21/+6
According to this kernel commit 2adc376c55194, d_ino 0 is a regular inode number on Linux (which also matches POSIX, as it does not treat the value as special). This patch makes glob accept is a valid inode number. This is also a sync with gnulib commit c8e57c1. Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py for all major architectures. [BZ #1062] [BZ #19971] * posix/glob.c (struct readdir_result): Remove skip_entry member.

2017-09-08posix: Sync glob with gnulib [BZ #1062]Adhemerval Zanella22-459/+739
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.

2017-09-05Prefer new libm function wrappers for !LIBM_SVID_COMPAT.Joseph Myers165-70/+535
The initial obsoletion of SVID libm error handling left the old wrappers and __kernel_standard still being used for new ports and static linking, just with macro definitions of _LIB_VERSION and matherr that meant symbols with those names were never actually used and the code for different error handling variants could be optimized out. This patch cleans things up further by eliminating the __kernel_standard use for new ports and static linking. Now, the old wrappers no longer generate any code in the !LIBM_SVID_COMPAT case, while the new errno-only wrappers that were added for float128 support are now also used for float, double and long double in that case. The changes are generally straightforward. The w_scalb*_compat wrappers continue to be used (scalb is obsolescent in the sense of not being supported for float128, but is present in supported standards - the 2001 edition of POSIX and earlier XSI versions - so remains supported for static linking and new ports, as do the float and long double variants that are existing GNU extensions). Those wrappers would only call __kernel_standard in the _LIB_VERSION == _SVID_ case. Since we would like to be able to compile most of glibc without optimization, relying on a static function whose only use is under an if (0) condition being optimized away to avoid an undefined __kernel_standard reference may not be a good idea. Thus, the relevant code in the scalb wrappers has LIBM_SVID_COMPAT conditionals added to guarantee it's not built at all in the case where __kernel_standard does not exist. Just as i386 has its own w_sqrt_compat.c, so w_sqrt.c is also added. ia64 gets dummy w_*.c to prevent those files being built where they would conflict with the ia64 libm, as with its existing w_*_compat.c. Conditions disabling code for !LIBM_SVID_COMPAT are needed in both the math/ wrappers and in the long double wrappers in ldbl-opt (to avoid them setting up aliases and symbol versions for undefined symbols). I hope that future cleanups to how libm function aliases and symbol versioning are done will eliminate the need for most of the ldbl-opt wrappers.

2017-09-05Fix pcprofiledump cross-endian condition (bug 22086).Joseph Myers2-1/+7
debug/pcprofiledump.c contains code that tries to handle other-endian data. This uses a condition "(word & 0xfffffff0) == bswap_32 (0xdeb00000)". This condition is always false (the LHS always has the low four bits zero, the RHS doesn't); a correct comparison would use 0x0fffffff. This results in -Werror=tautological-compare build failures with the tile version of bits/byteswap.h and mainline GCC. https://sourceware.org/ml/libc-testresults/2017-q3/msg00400.html pcprofiledump.c: In function 'main': pcprofiledump.c:118:39: error: bitwise comparison always evaluates to false [-Werror=tautological-compare] int must_swap = (word & 0xfffffff0) == bswap_32 (0xdeb00000); ^~ This patch fixes the condition. Tested for x86_64, and with build-many-glibcs.py that it fixes the build for tilegx-linux-gnu. (Note that I have not tested the actual pcprofiledump functionality, native or cross endian, which lacks any testsuite coverage.)
