* powerpc: Fix logbl on power7 [BZ# 21280]Tulio Magno Quites Machado Filho2017-04-282-6/+25
| | | | | | | | | | | | | | | | | 1. Fix the results for negative subnormals by ignoring the signal when normalizing the value. 2. Fix the output when the high part is a power of 2 and the low part is a nonzero number with opposite sign. This fix is based on commit 380bd0fd2418f8988217de950f8b8ff18af0cb2b. After applying this patch, logbl() tests pass cleanly on POWER >= 7. Tested on powerpc, powerpc64 and powerpc64le [BZ #21280] * sysdeps/powerpc/power7/fpu/s_logbl.c (__logbl): Ignore the signal of subnormals and adjust the exponent of power of 2 down when low part has opposite sign.

* conformtest: Allow time.h inclusion from semaphore.h for XOPEN2K.Joseph Myers2017-04-283-2/+10
| | | | | | | | | | | | | | | | POSIX.1:2001 added sem_timedwait, but said nothing about defining struct timespec in semaphore.h. The 2008 edition added a corresponding permission to include <time.h> from <semaphore.h>. Since this is the normal POSIX approach in such cases, it seems appropriate to consider this a bug fix, and so this patch makes the conform/ tests allow that inclusion for POSIX.1:2001 as well. Tested for x86_64. * conform/data/semaphore.h-data [XOPEN2K] (time.h): Allow header inclusion. * conform/Makefile (test-xfail-XOPEN2K/semaphore.h/conform): Remove.
* conformtest: Fix XPG standard naming.Joseph Myers2017-04-2764-224/+291
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The conform/ tests test -D_XOPEN_SOURCE under the name "XPG3", and -D_XOPEN_SOURCE -D_XOPEN_SOURCE_EXTENDED under the name "XPG4". That naming is misleading. _XOPEN_SOURCE_EXTENDED actually means XPG4.2, including UX-shaded interfaces. _XOPEN_SOURCE actually means XPG4, or XPG4.2 without UX-shaded interfaces. (Prior XPG versions also used _XOPEN_SOURCE, but without any versioning of the values of the macro, so XPG4.2 without UX-shaded interfaces is the only sensible set of interfaces for glibc to expose given _XOPEN_SOURCE=1 without _XOPEN_SOURCE_EXTENDED defined.) This patch fixes the naming in the conform/ tests, so that what is now called XPG4 is changed to XPG42, and what is now called XPG3 is changed to XPG4. Tested for x86_64 (and verified the complete set of expectations is unchanged by the patch beyond the intended renaming). * conform/GlibcConform.pm (XPG4): Rename standard to XPG42.

* Default build-many-glibcs.py to GCC 7 branch.Joseph Myers2017-04-262-1/+6
| | | | | | | | | | | | | Now there is a GCC 7 release branch, this patch makes build-many-glibcs.py default to using it instead of GCC 6. Relative to GCC 6, this fixes the MicroBlaze build but introduces ICEs building glibc testcases for SH (GCC PRs 78459, 78460; the latter is an out-of-memory issue so you may want to set memory limits when running build-many-glibcs.py). * scripts/build-many-glibcs.py (Context.checkout): Default gcc version to 7 branch.

| | | | | | | | | | | | When using software completions, we have to prevent assembler to match input and output operands of sqrtt/sqrtf insn. Add earlyclobber to output operand to avoid unwanted operand matching. 2017-04-14 Uros Bizjak <ubizjak@gmail.com> * sysdeps/alpha/fpu/math_private.h (__ieee754_sqrt): Add earlyclobber to output operand of sqrt insn.

* Fix sys/socket.h namespace issues from sys/uio.h inclusion (bug 21426).Joseph Myers2017-04-2511-21/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sys/socket.h includes sys/uio.h to get the definition of the iovec structure. POSIX allows sys/socket.h to make all sys/uio.h symbols visible. However, all of sys/uio.h is XSI-shaded, so for non-XSI POSIX this results in conformtest failures (for sys/socket.h and other headers that include it): Namespace violation: "UIO_MAXIOV" Namespace violation: "readv" Namespace violation: "writev" Now, there is some ambiguity in POSIX about what namespace reservations apply in this case - see http://austingroupbugs.net/view.php?id=1127 - but glibc convention would still avoid declaring readv and writev, for example, for feature test macros that don't include them (if only headers from the relevant standard are included), even if such declarations are permitted, so there is a bug here according to glibc conventions. This patch moves the struct iovec definition to a new bits/types/struct_iovec.h header and includes that from sys/socket.h instead of including the whole of sys/uio.h. This fixes the namespace issue; however, three files in glibc that were relying on the implicit inclusion needed to be updated to include sys/uio.h explicitly. So there is a question of whether sys/socket.h should continue to include sys/uio.h under some conditions, such as __USE_XOPEN or __USE_MISC or __USE_XOPEN || __USE_MISC, for greater compatibility with code that (wrongly) expects this optional inclusion to be present there. (I think the three affected files in glibc should still have explicit sys/uio.h inclusions added in any case, however.) Tested for x86_64. [BZ #21426] * misc/bits/types/struct_iovec.h: New file. * misc/Makefile (headers): Add bits/types/struct_iovec.h. * include/bits/types/struct_iovec.h: New file. * bits/uio.h (struct iovec): Replace by inclusion of <bits/types/struct_iovec.h>. * sysdeps/unix/sysv/linux/bits/uio.h (struct iovec): Likewise. * socket/sys/socket.h: Include <bits/types/struct_iovec.h> instead of <sys/uio.h>. * nptl/tst-cancel4.c: Include <sys/uio.h> * posix/test-errno.c: Likewise. * support/resolv_test.c: Likewise. * conform/Makefile (test-xfail-POSIX2008/arpa/inet.h/conform): Remove.

* conformtest: Allow *_t in sys/socket.h.Joseph Myers2017-04-252-0/+5
| | | | | | | | | | | | | | | The conformtest expectations in sys/socket.h are missing the standard POSIX allowance for all headers to define *_t names. For XSI standard versions that allowance comes in via the permission to include <sys/uio.h> (for which the expectations properly allow *_t), but for non-XSI POSIX nothing brings in that allowance and spurious namespace failures occur. This patch adds the required permission to the expectations to remove the spurious failures (by itself this does not allow any XFAILs to be removed). Tested for x86_64. * conform/data/sys/socket.h-data (*_t): Allow.

* Macroize function declarations in math_private.hGabriel F. T. Gomes2017-04-243-170/+154
| | | | | | | | | | | | | | | | | This patch moves the declaration of many floating-point functions from math_private.h to math_private_calls.h and macroize the declaration to be dependent on floating-point type. For each of float, double, and long double, the new header file is included once. This reduces the amount of repetitive boilerplate that will be required when adding float128 versions of these functions. Tested for powerpc64le and s390x. * sysdeps/generic/math_private.h: Move the declaration of many functions to sysdeps/generic/math_private_calls.h. * sysdeps/generic/math_private_calls.h: New file with the declarations of the functions removed from math_private.h macroized by floating-point type.
* S390: Move utf8-utf32-z9.c to multiarch folder and use s390_libc_ifunc_expr ↵Stefan Liebler2017-04-213-103/+169
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | macro. The utf8-utf32-z9.c iconv module is using ifunc and thus the ifunc part should be in multiarch folder. Otherwise ifunc is used even if you configure with --disable-multi-arch. This patch moves the ifunc resolvers to the new file sysdeps/s390/multiarch/utf8-utf32-z9.c. The resolvers are now implemented with s390_libc_ifunc_expr macro instead of using gcc attribute ifunc directly. The ifunc versions are implemented in sysdeps/s390/utf8-utf32-z9.c. Each version is only implemented if needed or supported. Therefore there is a block at beginning of the file which selects the versions which should be defined depending on support for multiarch, vector-support and used minimum architecture level. This block defines HAVE_[FROM|TO]_[C|CU|VX] to 1 or 0. The code below is rearranged and surrounded by #if HAVE_[FROM|TO]_[C|CU|VX] == 1. There is no functional change. The cu instructions are z9 zarch instructions. As the major distros are already using the newer z196 as architecture level set, those instructions can be used as fallback version instead of the c-code. This behaviour is decided at compile time via HAVE_S390_MIN_Z196_ZARCH_ASM_SUPPORT.

* S390: Use new s390_libc_ifunc_expr macro in s390 8bit-generic.c.Stefan Liebler2017-04-213-29/+25
| | | | | | | | | | | | | | | | | | | This patch adds s390_libc_ifunc_expr macro which uses the __ifunc base macro in include/libc-symbols.h and lets the user define a generic expression to choose the correct ifunc variant. Furthermore as the base macro is used, the ifunc resolver functions are now also using inhibit_stack_protector. S390 needs its own version due to the hwcap argument of the ifunc resolver. This new macro is now used in iconv code in 8bit-generic.c instead of using gcc attribute ifunc directly.

* Do not use wildcard symbol names for public versions in Versions files.Joseph Myers2017-04-203-2/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As noted in <https://sourceware.org/ml/libc-alpha/2012-12/msg00240.html>, stdlib/Versions and wcsmbs/Versions list some functions as __strto*_internal and __wcsto*_internal rather than explicitly listing the symbols to be exported (so any new internal function matching one of those patterns would be wrongly added to version GLIBC_2.0), which seems like a bad idea. This patch changes those files to list the exported symbols explicitly. There are still entries in sysdeps/nacl/Versions for __nacl_irt_*, but as GLIBC_PRIVATE symbols that seems less significant. Tested with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * stdlib/Versions (__strtod_internal): List explicitly, not as wildcard.

* Fix missing timespec definition for sys/stat.h (BZ #21371)Adhemerval Zanella2017-04-202-1/+6
| | | | | | | | | | | | | | | | | | | As indicated by the bug report, the 'struct timespec' definition is not defined for '_XOPEN_SOURCE=700' and '_POSIX_C_SOURCE=200112L'. It is because current code only includes its definition if __USE_ATFILE is defined and the define is only set with: 1. _GNU_SOURCE and/or _ATFILE_SOURCE definition. 2. _POSIX_C_SOURCE >= 200809L However, the 'st_*' fields in 'struct stat' are defined if __USE_XOPEN2K8. This patch uses the same logic for 'struct timespec' inclusion. Tested on x86_64-linux-gnu. * io/sys/stat.h: Use __USE_XOPEN2K8 insteaf of __USE_ATFILE for struct timespec definition.

* Assume that accept4 is always available and worksFlorian Weimer2017-04-1916-138/+230
| | | | | | | | | | Simplify the Linux accept4 implementation based on the assumption that it is available in some way. __ASSUME_ACCEPT4_SOCKETCALL was previously unused, so remove it. For ia64, the accept4 system call (and socket call) were backported in kernel version 3.2.18. Reflect this in the installation instructions.
* conformtest: Enable tests when cross compiling.Joseph Myers2017-04-182-2/+5
| | | | | | | | | | | | | This patch enables the compilation part of the conformtest tests (the vast bulk of them) when cross compiling, so making it easy to run them across many configurations with build-many-glibcs.py. Tested with build-many-glibcs.py. * conform/Makefile (tests-special): Do not make addition of $(conformtest-header-tests) conditional on [$(cross-compiling) = no]. (generated): Do not make addition of $(conformtest-header-base) conditional on [$(cross-compiling) = no].
* Fix bits/socket.h IOC* namespace issues (bug 21267).Joseph Myers2017-04-182-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysdeps/unix/sysv/linux/bits/socket.h includes asm/socket.h. That includes asm/sockios.h, which on MIPS includes asm/ioctl.h, resulting in namespace violations from IOC* macros. bits/socket.h already has code to handle asm/socket.h unconditionally defining macros that are only wanted for __USE_MISC. This patch extends it to handle the IOC* macros as well (always undefining them if not defined when bits/socket.h was included, as I don't think they are part of the intended API even for __USE_MISC). It's possible there should also be a kernel fix - it's not clear to me that IOC* belong in the uapi headers, and even if they do they might best be split out into another header to avoid getting defined by this particular path. But since glibc needs to deal with existing kernel headers, it also seems appropriate to extend the existing workaround to these macros. Tested (compilation only) with build-many-glibcs.py. [BZ #21267] * sysdeps/unix/sysv/linux/bits/socket.h (IOCSIZE_MASK): Undefine if defined by <asm/socket.h> and not previously defined. (IOCSIZE_SHIFT): Likewise. (IOC_IN): Likewise.

* x86: Use AVX2 memcpy/memset on Skylake server [BZ #21396]H.J. Lu2017-04-1811-1/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Skylake server, AVX512 load/store instructions in memcpy/memset may lead to lower CPU turbo frequency in certain situations. Use of AVX2 in memcpy/memset has been observed to have improved overall performance in many workloads due to the higher frequency. Since AVX512ER is unique to Xeon Phi, this patch sets Prefer_No_AVX512 if AVX512ER isn't available so that AVX2 versions of memcpy/memset are used on Skylake server. [BZ #21396] * sysdeps/x86/cpu-features.c (init_cpu_features): Set Prefer_No_AVX512 if AVX512ER isn't available. * sysdeps/x86/cpu-features.h (bit_arch_Prefer_No_AVX512): New.

| | | | | | | | | | | | | | | | | | | | | | | | | | | AVX512ER won't be implemented in any Xeon processors and will be in all Xeon Phi processors. Don't check CPU model number when setting Prefer_No_VZEROUPPER for Xeon Phi. Instead, set Prefer_No_VZEROUPPER if AVX512ER is available. It works with current and future Xeon Phi and non-Xeon Phi processors. * sysdeps/x86/cpu-features.c (init_cpu_features): Set Prefer_No_VZEROUPPER if AVX512ER is available. * sysdeps/x86/cpu-features.h (bit_cpu_AVX512PF): New.

| | | | | | | P7 code is used for <=32B strings and for > 32B vectorized loops are used. This shows as an average 25% improvement depending on the position of search character. The performance is same for shorter strings. Tested on ppc64 and ppc64le.
* [BZ 21357] unwind-dw2-fde: Call free() outside of unwind mutexRabin Vincent2017-04-172-1/+9
| | | | | | | | | | | | | __deregister_frame_info_bases() calls free() while holding a mutex which is also used from _Unwind_Find_FDE(). This leads to a deadlock if AddressSanitizer uses _Unwind_Backtrace() from its free() implementation. Checked on mips-linux-gnu and x86_64-linux-gnu. [BZ #21357] * sysdeps/generic/unwind-dw2-fde.c (__deregister_frame_info_bases): Call free() outside of mutex.

* resolv: Remove EDNS fallback [BZ #21369]Florian Weimer2017-04-135-64/+77
| | | | | | EDNS is disabled by default (so there is interoperability issue), and the fallback code is problematic because it prevents an application from obtaining DNSSEC data after a FORMERR response.
* resolv: Reduce EDNS payload size to 1200 bytes [BZ #21361]Florian Weimer2017-04-1310-14/+652

* resolv: Support an exactly sized buffer in ns_name_pack [BZ #21359]Florian Weimer2017-04-136-4/+260
| | | | | | | This bug did not affect name resolution because those functions indirectly call ns_name_pack with a buffer which is always larger than the generated query packet, even in the case of the longest-possible domain name.
* resolv: Remove internal and unused definitions from <resolv.h>Florian Weimer2017-04-136-20/+24
| | | | | | | The RES_F_* constants are only used with the private _res._flags member. RES_EXHAUSTIVE is unused. The removed function declarations refer to functions not actually exported by glibc, so they are unusable by applications.
* powerpc: Optimized strncat for POWER8Rajalakshmi Srinivasaraghavan2017-04-135-2/+50
| | | | | | | | | | | | | | | | | | With new optimized strnlen for POWER8 [1], this patch adds strncat for power8 to make use of optimized strlen and strnlen. This is faster than POWER7 current implementation for larger strings. Tested on powerpc64 and powerpc64le. [1] https://sourceware.org/ml/libc-alpha/2017-03/msg00491.html * sysdeps/powerpc/powerpc64/multiarch/Makefile (sysdep_routines): Add strncat-power8. * sysdeps/powerpc/powerpc64/multiarch/strncat.c (strncat): Add __strncat_power8 to ifunc list. * sysdeps/powerpc/powerpc64/multiarch/ifunc-impl-list.c (strncat): Add __strncat_power8 to list of strncat functions. * sysdeps/powerpc/powerpc64/multiarch/strncat-power8.c: New file.
* Consolidate Linux mmap implementation (BZ#21270)Adhemerval Zanella2017-04-1225-584/+275
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch consolidates all Linux mmap implementations on default sysdeps/unix/sysv/linux/mmap{64}.c one. To accomodate all required architecture specific requeriments a new internal header is created (mmap_internal.h) where each architecture add its specific code requirements. Currently only x86_64 (to define MMAP_PREPARE to add MAP_32BITS), s390 (which have a different kernel ABI for mmap), m68k (which have variable minimum page sizes), and MIPS n32 (which zero extend the offset to handle negative one correctly) redefine the new header. The patch also fixes BZ#21270 where default mmap64 on architectures which uses mmap2 silent truncates large offsets value (larger than 1 << (page shift + 8 * sizeof (off_t)) or 1<<44 on architectures with 4096 bytes page size). The new consolidate implementation returns EINVAL as allowed by POSIX. It also adds a tests for on current tst-mmap-offset one. I have run a full make check on x86_64, x86_64-32, i686, aarch64, armhf, powerpc, powerpc64le, sparc64, and sparcv9 without any regressions. I also ran some basic tests (tst-mmap-offset) on sh4, m68k, and on qemu simulated MIPS32 and MIPS64. [BZ #21270] * posix/tst-mmap-offset.c (do_prepare): New function.
