Add roundeven, roundevenf, roundevenl.
TS 18661-1 defines roundeven functions that round a floating-point number to the nearest integer, in that floating-point type, with ties rounding to even (whereas the round functions round ties away from zero). As with other such functions, they raise no exceptions apart from "invalid" for signaling NaNs. There was a previous user request for this functionality in glibc in <https://sourceware.org/ml/libc-help/2015-02/msg00005.html>. This patch implements these functions for glibc. The implementations use integer bit-manipulation (or roundeven on the high and low parts, in the IBM long double case). It's possible that there may be faster approaches on some architectures (in particular, on AArch64 the frintn instruction should do exactly what's required); I'll leave it to architecture maintainers or others interested to implement such architecture-specific versions if desired. (Where architectures have instructions to round to nearest integer in the current rounding mode, implementations saving and restoring the rounding mode - and dealing with exceptions if those instructions generate "inexact" - are also possible, though their performance depends on the cost of manipulating exceptions / rounding mode state.) Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (roundeven): New declaration. * math/tgmath.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (roundeven): New macro. * math/Versions (roundeven): New libm symbol at version GLIBC_2.25.

TS 18661-1 defines fmaxmag and fminmag functions that return the argument with maximum / minimum magnitude (acting like fmax / fmin if the arguments have the same magnitude or either argument is a NaN).

New string function explicit_bzero (from OpenBSD).
explicit_bzero(s, n) is the same as memset(s, 0, n), except that the compiler is not allowed to delete a call to explicit_bzero even if the memory pointed to by 's' is dead after the call. Right now, this effect is achieved externally by having explicit_bzero be a function whose semantics are unknown to the compiler, and internally, with a no-op asm statement that clobbers memory. This does mean that small explicit_bzero operations cannot be expanded inline as small memset operations can, but on the other hand, small memset operations do get deleted by the compiler. Hopefully full compiler support for explicit_bzero will happen relatively soon. There are two new tests: test-explicit_bzero.c verifies the visible semantics in the same way as the existing test-bzero.c, and tst-xbzero-opt.c verifies the not-being-optimized-out property. The latter is conceptually based on a test written by Matthew Dempsky for the OpenBSD regression suite. The crypt() implementation has an immediate use for this new feature. We avoid having to add a GLIBC_PRIVATE alias for explicit_bzero by running all of libcrypt's calls through the fortified variant, __explicit_bzero_chk, which is in the impl namespace anyway. Currently I'm not aware of anything in libc proper that needs this, but the glue is all in place if it does become necessary. The legacy DES implementation wasn't bothering to clear its buffers, so I added that, mostly for consistency's sake. * string/explicit_bzero.c: New routine. * string/test-explicit_bzero.c, string/tst-xbzero-opt.c: New tests. * string/Makefile (routines, strop-tests, tests): Add them. * string/test-memset.c: Add ifdeffage for testing explicit_bzero. * string/string.h [__USE_MISC]: Declare explicit_bzero. * debug/explicit_bzero_chk.c: New routine. * debug/Makefile (routines): Add it. * debug/tst-chk1.c: Test fortification of explicit_bzero. * string/bits/string3.h: Fortify explicit_bzero. * manual/string.texi: Document explicit_bzero. * NEWS: Mention addition of explicit_bzero. * crypt/crypt-entry.c (__crypt_r): Clear key-dependent intermediate data before returning, using explicit_bzero. * crypt/md5-crypt.c (__md5_crypt_r): Likewise. * crypt/sha256-crypt.c (__sha256_crypt_r): Likewise. * crypt/sha512-crypt.c (__sha512_crypt_r): Likewise. * include/string.h: Redirect internal uses of explicit_bzero to __explicit_bzero_chk[_internal]. * string/Versions [GLIBC_2.25]: Add explicit_bzero. * debug/Versions [GLIBC_2.25]: Add __explicit_bzero_chk. * sysdeps/arm/nacl/libc.abilist * sysdeps/unix/sysv/linux/aarch64/libc.abilist * sysdeps/unix/sysv/linux/alpha/libc.abilist * sysdeps/unix/sysv/linux/arm/libc.abilist * sysdeps/unix/sysv/linux/hppa/libc.abilist * sysdeps/unix/sysv/linux/i386/libc.abilist * sysdeps/unix/sysv/linux/ia64/libc.abilist * sysdeps/unix/sysv/linux/m68k/coldfire/libc.abilist * sysdeps/unix/sysv/linux/m68k/m680x0/libc.abilist * sysdeps/unix/sysv/linux/microblaze/libc.abilist * sysdeps/unix/sysv/linux/mips/mips32/fpu/libc.abilist * sysdeps/unix/sysv/linux/mips/mips32/nofpu/libc.abilist * sysdeps/unix/sysv/linux/mips/mips64/n32/libc.abilist * sysdeps/unix/sysv/linux/mips/mips64/n64/libc.abilist * sysdeps/unix/sysv/linux/nios2/libc.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libc.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libc.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc-le.abilist * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc.abilist * sysdeps/unix/sysv/linux/s390/s390-32/libc.abilist * sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist * sysdeps/unix/sysv/linux/sh/libc.abilist * sysdeps/unix/sysv/linux/sparc/sparc32/libc.abilist * sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libc.abilist * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libc.abilist * sysdeps/unix/sysv/linux/tile/tilepro/libc.abilist * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist * sysdeps/unix/sysv/linux/x86_64/x32/libc.abilist: Add entries for explicit_bzero and __explicit_bzero_chk. |

Refactor long double information into bits/long-double.h.
Information about whether the ABI of long double is the same as that of double is split between bits/mathdef.h and bits/wordsize.h. When the ABIs are the same, bits/mathdef.h defines __NO_LONG_DOUBLE_MATH. In addition, in the case where the same glibc binary supports both -mlong-double-64 and -mlong-double-128, bits/wordsize.h defines __LONG_DOUBLE_MATH_OPTIONAL, along with __NO_LONG_DOUBLE_MATH if this particular compilation is with -mlong-double-64. As part of the refactoring I proposed in <https://sourceware.org/ml/libc-alpha/2016-11/msg00745.html>, this patch puts all that information in a single header, bits/long-double.h. It is included from sys/cdefs.h alongside the include of bits/wordsize.h, so other headers generally do not need to include bits/long-double.h directly. Previously, various bits/mathdef.h headers and bits/wordsize.h headers had this long double information (including implicitly in some bits/mathdef.h headers through not having the defines present in the default version). After the patch, it's all in six bits/long-double.h headers. Furthermore, most of those new headers are not architecture-specific. Architectures with optional long double all use the ldbl-opt sysdeps directory, either in the order (ldbl-64-128, ldbl-opt, ldbl-128) or (ldbl-128ibm, ldbl-opt). Thus a generic header for the case where long double = double, and headers in ldbl-128, ldbl-96 and ldbl-opt, suffices to cover every architecture except for cases where long double properties vary between different ABIs sharing a set of installed headers; fortunately all the ldbl-opt cases share a single compiler-predefined macro __LONG_DOUBLE_128__ that can be used to tell whether this compilation is -mlong-double-64 or -mlong-double-128. The two cases where a set of headers is shared between ABIs with different long double properties, MIPS (o32 has long double = double, other ABIs use ldbl-128) and SPARC (32-bit has optional long double, 64-bit has required long double), need their own bits/long-double.h headers. As with bits/wordsize.h, multiple-include protection for this header is generally implicit through the include guards on sys/cdefs.h, and multiple inclusion is harmless in any case. There is one subtlety: the header must not define __LONG_DOUBLE_MATH_OPTIONAL if __NO_LONG_DOUBLE_MATH was defined before its inclusion, because doing so breaks how sysdeps/ieee754/ldbl-opt/nldbl-compat.h defines __NO_LONG_DOUBLE_MATH itself before including system headers. Subject to keeping that working, it would be reasonable to move these macros from defined/undefined #ifdef to always-defined 1/0 #if semantics, but this patch does not attempt to do so, just rearranges where the macros are defined. After this patch, the only use of bits/mathdef.h is the alpha one for modifying complex function ABIs for old GCC. Thus, all versions of the header other than the default and alpha versions are removed, as is the include from math.h. Tested for x86_64 and x86. Also did compilation-only testing with build-many-glibcs.py. * bits/long-double.h: New file. * sysdeps/ieee754/ldbl-128/bits/long-double.h: Likewise. * sysdeps/ieee754/ldbl-96/bits/long-double.h: Likewise. * sysdeps/ieee754/ldbl-opt/bits/long-double.h: Likewise. * sysdeps/mips/bits/long-double.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/long-double.h: Likewise. * math/Makefile (headers): Add bits/long-double.h. * misc/sys/cdefs.h: Include <bits/long-double.h>. * stdlib/strtold.c: Include <bits/long-double.h> instead of <bits/wordsize.h>. * bits/mathdef.h [!_COMPLEX_H]: Do not allow inclusion.

Add llogb, llogbf, llogbl.
TS 18661-1 defines llogb functions that are like ilogb except that they return long int instead of int. Corresponding FP_LLOGB* macros are defined, whose values are required to have the obvious correspondence to those of the FP_ILOGB* macros. This patch implements these functions and macros for glibc. llogb uses the type-generic infrastructure, with an implementation similar to the wrapper for ilogb but with additional conversion from FP_ILOGB* to FP_LLOGB*; this approach avoids needing to modify or duplicate any of the architecture-specific ilogb implementations. Tests are also based on those for ilogb. Ideally the llogb functions would alias the ilogb ones when long is 32-bit, but such aliasing requires the associated header declarations of the different-type alias to be hidden, typically by defining macros before including the header (see e.g. how sysdeps/ieee754/dbl-64/wordsize-64/s_llround.c defines lround to __hidden_lround before including <math.h>). The infrastructure for type-generic function implementations does not support defining such macros at present (since C code can't define a macro whose name is determined by other macros). So this patch leaves them as separate functions (similar to e.g. scalbln and scalbn being separate in such a case as well), but with the remapping of FP_ILOGB* to FP_LLOGB* conditioned out in the case where it would be the identity map. Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (llogb): New declaration. * math/tgmath.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (llogb): New macro. * math/math.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (__FP_LONG_MAX): New macro.

Implement _dl_catch_error, _dl_signal_error in libc.so [BZ #16628]
This change moves the main implementation of _dl_catch_error, _dl_signal_error to libc.so, where TLS variables can be used directly. This removes a writable function pointer from the rtld_global variable. For use during initial relocation, minimal implementations of these functions are provided in ld.so. These are eventually interposed by the libc.so implementations. This is implemented by compiling elf/dl-error-skeleton.c twice, via elf/dl-error.c and elf/dl-error-minimal.c. As a side effect of this change, the static version of dl-error.c no longer includes support for the _dl_signal_cerror/_dl_receive_error mechanism because it is only used in ld.so. |

Add setpayloadsig, setpayloadsigf, setpayloadsigl.
TS 18661-1 defines functions for manipulating the payloads of NaNs. This patch implements the setpayloadsig functions for glibc; these are like the setpayload functions, but produce a signaling NaN instead of a quiet NaN. The substance of the implementation was included with the setpayload implementation, so the new files here just need to wrap the main files with different defines to build the new functions. Because the functions store a signaling NaN via a pointer and the libm-test macros choose a suitable initial value for the variable in such a case by comparing with the expected value, the relevant macro needs to clear exceptions after FE_INVALID may have been raised by that comparison.

Remove cached PID/TID in clone
This patch remove the PID cache and usage in current GLIBC code. Current usage is mainly used a performance optimization to avoid the syscall, however it adds some issues: - The exposed clone syscall will try to set pid/tid to make the new thread somewhat compatible with current GLIBC assumptions. This cause a set of issue with new workloads and usecases (such as BZ#17214 and [1]) as well for new internal usage of clone to optimize other algorithms (such as clone plus CLONE_VM for posix_spawn, BZ#19957). - The caching complexity also added some bugs in the past [2] [3] and requires more effort of each port to handle such requirements (for both clone and vfork implementation). - Caching performance gain in mainly on getpid and some specific code paths. The getpid performance leverage is questionable [4], either by the idea of getpid being a hotspot as for the getpid implementation itself (if it is indeed a justifiable hotspot a vDSO symbol could let to a much more simpler solution). Other usage is mainly for non usual code paths, such as pthread cancellation signal and handling. For thread creation (on stack allocation) the code simplification in fact adds some performance gain due the no need of transverse the stack cache and invalidate each element pid. Other thread usages will require a direct getpid syscall, such as cancellation/setxid signal, thread cancellation, thread fail path (at create_thread), and thread signal (pthread_kill and pthread_sigqueue). However these are hardly usual hotspots and I think adding a syscall is justifiable. It also simplifies both the clone and vfork arch-specific implementation. And by review each fork implementation there are some discrepancies that this patch also solves: - microblaze clone/vfork does not set/reset the pid/tid field - hppa uses the default vfork implementation that fallback to fork. Since vfork is deprecated I do not think we should bother with it. The patch also removes the TID caching in clone. My understanding for such semantic is try provide some pthread usage after a user program issue clone directly (as done by thread creation with CLONE_PARENT_SETTID and pthread tid member). However, as stated before in multiple discussions threads, GLIBC provides clone syscalls without further supporting all this semantics. I ran a full make check on x86_64, x32, i686, armhf, aarch64, and powerpc64le. For sparc32, sparc64, and mips I ran the basic fork and vfork tests from posix/ folder (on a qemu system). So it would require further testing on alpha, hppa, ia64, m68k, nios2, s390, sh, and tile (I excluded microblaze because it is already implementing the patch semantic regarding clone/vfork).

Add setpayload, setpayloadf, setpayloadl.
TS 18661-1 defines functions for manipulating the payloads of NaNs. This patch implements the setpayload functions for glibc; these set a number (pointed to by a function argument) to a quiet NaN with the given payload, or to +0 if the given payload is not valid. The implementations are structured to allow the substance of the implementation to be shared with the setpayloadsig functions when those are added. The semantics in the TS are not entirely clear in the case where the payload passed to the function is zero (see discussion on the WG14 reflector last month). This patch implements what seems the most sensible interpretation, that -0 is never valid to give as the payload, but +0 is valid in the case where the kind of NaN being generated has its high mantissa bit set so payload 0 is actually possible in such a NaN. Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (setpayload): New declaration. * math/Versions (setpayload): New libm symbol at version GLIBC_2.25.

Consolidate Linux setrlimit and getrlimit implementation
This patch consolidates all Linux setrlimit and getrlimit on the default
sysdeps/unix/sysv/linux/{set,get}rlimit{64}.c. It contains two exceptions:
1. mips32 and mips64n32 which requires a versioned symbol for GLIBC 2.19
and higher due a broken RLIM64_INFINITY constant.
2. sparc32 does not define a compat symbol for getrlimit64 for old 2GB
limit. I am not sure if it is required, but a RLIM_INFINITY fix [1]
change its definition without adding a compat symbol. This patch does
not aim to address this possible issue, it follow current symbol
export.
The default implementation uses prlimit64 for 64 bit rlim_t ({set,get}rlimit64)
and if it fails with ENOSYS it fall back to {get,set}rlimit syscall. This
code path is only used on kernel older than 2.6.36 (basically now only x86)
and I avoid to user __ASSUME_PRLIMTI64 to simplify the implementation. Once
x86 moves to be on par with other architectures regarding minimum kernel
supported we can get rid of using old syscalls and default path.
A new type size define is added, __RLIM_T_MATCHES_RLIM64_T, where is set as
default for 64 bits ports. This allows the default implementation to avoid
{get,set}rlimit building and alias {get,set}rlimit64 to {get,set}rlimit.
Checked on x86_64, i386, armhf, aarch64, and powerpc64le. I also did a
sanity build plus check-abi on all other supported architectures.

Add canonicalize, canonicalizef, canonicalizel.
TS 18661-1 defines canonicalize functions to produce a canonical version of a floating-point representation. This patch implements these functions for glibc. As with the iscanonical macro, these functions are oriented to the decimal floating-point case, where some values have both canonical and noncanonical representations. However, the functions have a return value that says whether they succeeded in storing a canonical result; thus, they can fail for the case of an invalid representation (while still not making any particular choice from among multiple equally canonical valid representations of the same value). Since no floating-point formats in glibc actually have noncanonical valid representations, a type-generic implementation of these functions can be used that expects iscanonical to return 0 only for invalid representations. Now that iscanonical is used within libm.so, libm_hidden_proto / libm_hidden_def are added for __iscanonicall. The definition of these functions is intended to correspond to a convertFormat operation to the same floating-point format. Thus, they convert signaling NaNs to quiet NaNs, raising the "invalid" exception. Such a conversion "should" produce "the canonical version of that signaling NaN made quiet". libm-test.inc is made to check NaN payloads for the output of these functions, a new feature (at some point manipulation functions such as fabs and copysign should have tests added that verify payload preservation for them). As however some architectures may not follow the recommended practice of preserving NaN payloads when converting a signaling NaN to quiet, a new math-tests.h macro SNAN_TESTS_PRESERVE_PAYLOAD is added, and defined to 0 for non-NAN2008 MIPS; any other architectures seeing test failures for lack of payload preservation in this case should also define this macro to 0. (If any cases arise where the sign isn't preserved either, those should have a similar macro added.) The ldbl-96 and ldbl-128ibm tests of iscanonical are renamed and adapted to test canonicalizel as well on the same representations.

Add getpayload, getpayloadf, getpayloadl.
TS 18661-1 defines functions for manipulating the payloads of NaNs. This patch implements the getpayload functions for glibc; these extract the NaN payload (from an argument passed as a pointer, for which corresponding libm-test support is added) and return it in the same floating-point type. The return value of these functions is unspecified for non-NaN arguments; the patch does the simplest thing to implement, which is that the functions do not check whether the argument is a NaN and just treat the relevant bits of the representation as a payload regardless. A conversion from integer to floating-point is used to produce the required return value, except in the ldbl-128 case; as 128-bit integers are not supported for all configurations using ldbl-128, the code constructs the required floating-point representation of the return value directly instead.

Add totalorder, totalorderf, totalorderl.
TS 18661-1 defines totalorder functions implementing the totalOrder comparison operation from IEEE 754-2008. This patch implements these functions for glibc, including the type-generic macro in <tgmath.h>. (The totalordermag functions will be added in a separate patch.) The description of the totalOrder operation is complicated. However, for IEEE interchange binary formats and the preferred quiet NaN convention, what that complicated description means is that you interpret the representation as a sign-magnitude integer (with -0 coming before +0) and do a <= comparison on that interpretation. For finite values and infinities the ordering of the sign-magnitude integers is just the same as the ordering of floating-point values, so this extends that to all representations. (Different representations of the same floating-point value - which includes same quantum in the decimal case - must still be considered equal by this operation, but that issue doesn't arise for IEEE interchange binary formats.) So the complications are: * When MIPS quiet NaN conventions are in use, the representation of NaNs needs adjusting before making such an integer comparison. This patch does this adjustment only when both arguments are NaNs, as there's no need for it if only one is a NaN, and as long as both are NaNs you can just flip the relevant bits without any problems from this turning a NaN into an infinity. * For the m68k version of ldbl-96, where the high mantissa bit is "don't care" for infinities and NaNs, representations where it differs must compare the same. Note: although the testcase for this compiles, I have not actually tested on m68k. * For ldbl-128ibm, the low part must be ignored when the high part is NaN, and low parts of +0 and -0 must be considered the same whatever the high part. The new tests in libm-test.inc are the first tests there specifying particular payloads for input NaNs. Separate tests are also added for the ldbl-96 and ldbl-128ibm special cases where there are different representations of the same value that must compare equal (which can't be covered in libm-test.inc as that only specifies values, not representations).

Consolidate Linux sync_file_range implementations
This patch consolidates all the sync_file_range implementation for Linux in only one (sysdeps/unix/sysv/linux/sync_file_range.c). It also removes the syscall from the auto-generation using assembly macros (except for x86_64 due x32 [1]). For current minimum supported kernel (2.6.32 for x86_64 and 3.2 for all other architectures) either sync_file_range or sync_file_range2 is supported and it is expected that any future Linux ABI will provide either of one syscall. So the code path that returns ENOSYS in the case of missing syscall is removed. Checked on x86_64, i386, powerpc64le, aarch64, and armhf. * sysdeps/unix/sysv/linux/Makefile (tests): Add tst-sync_file_range. * sysdeps/unix/sysv/linux/mips/mips32/sync_file_range.c: Remove file. * sysdeps/sysv/linux/powerpc/powerpc64/sync_file_range.c: Likewise. * sysdeps/unix/sysv/linux/sync_file_range.c: New file. * sysdeps/unix/sysv/linux/tst-sync_file_range.c (sync_file_range): Consolidate all Linux implementations.

It is the only supported port that implements __NR_fadvise64_64 in this way. * ARM: it does not implement __NR_fadvise64 (as other 32-bits ports), so posix_fadvise calls internal posix_fadvise64 symbol. * MIPS64 n64: it requires a different version number that other ports. The new macro SYSCALL_LL{64} is used to handle the offset argument and INTERNAL_SYSCALL_CALL to handle passing the correct number of expect arguments. The default Linux adds two new defines a port can use to control how __NR_fadvise64_64 passes the kernel arguments: * __ASSUME_FADVISE64_64_6ARG: the 'advise' argument is moved on second position. This is the case of powerpc32 and arm to avoid implement 7 argument syscall. * __ASSUME_FADVISE64_64_NO_ALIGN: for ABIs that defines __ASSUME_ALIGNED_REGISTER_PAIRS packs the offset without the leading '0'. This is the case of tile 32 bits. ARM also defines __NR_fadvise64_64 as __NR_arm_fadvise64_64 (which is also handled on arch kernel-feature.h). Tested on x86_64, x32, i686, armhf, and aarch64. * posix/Makefile (tests): Add tst-posix_fadvise and tst-posix_fadvise64. * posix/tst-posix_fadvise.c: New file. * posix/tst-posix_fadvise64.c: Likewise. * posix/tst-posix_fadvise-common.c: Likewise. * sysdeps/unix/sysv/linux/arm/kernel-features.h (__ASSUME_FADVISE64_64_6ARG): Define. * sysdeps/unix/sysv/linux/powerpc/kernel-features.h [!__powerpc64__] (__ASSUME_FADVISE64_64_6ARG): Add define. * sysdeps/unix/sysv/linux/arm/posix_fadvise64.c: Remove file. * sysdeps/unix/sysv/linux/generic/wordsize-32/posix_fadvise.c: Likewise. * sysdeps/unix/sysv/linux/i386/posix_fadvise64.S: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/posix_fadvise.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/posix_fadvise64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/posix_fadvise.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/posix_fadvise64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fadvise.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/posix_fadvise.c: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/posix_fadvise64.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/posix_fadvise.c: Likewise. * sysdeps/unix/sysv/linux/wordsize-64/posix_fadvise64.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/posix_fadvise64.c (SHLIB_COMPAT(libc, GLIBC_2_2, GLIBC_2_3_3) [__posix_fadvise64_l64]: Alias to __posix_fadvise64_l32.

ppc: Use libc_ifunc macro for time, gettimeofday.
This patch uses the libc_ifunc_hidden macro to create already existing ifunc functions time and gettimeofday on power. This way, the libc_hidden_def macro can be used instead of inline assemblies. On ppc32, the __GI_* symbols do not target the ifunc symbol and thus the redirection construct has to be applied here. ChangeLog: * sysdeps/unix/sysv/linux/powerpc/gettimeofday.c (__gettimeofday): Use libc_ifunc_hidden and libc_hidden_def macro. Redirect ifunced function in header for using it as type for ifunc function because __GI_* symbols for ppc32 do not target the ifunc symbols. * sysdeps/unix/sysv/linux/powerpc/time.c (time): Likewise. |

Add iseqsig.
TS 18661-1 adds an iseqsig type-generic comparison macro to <math.h>. This macro is like the == operator except that unordered operands result in the "invalid" exception and errno being set to EDOM. This patch implements this macro for glibc. Given the need to set errno, this is implemented with out-of-line functions __iseqsigf, __iseqsig and __iseqsigl (of which the last only exists at all if long double is ABI-distinct from double, so no function aliases or compat support are needed). The present patch ignores excess precision issues; I intend to deal with those in a followup patch. (Like comparison operators, type-generic comparison macros should *not* convert operands to their semantic types but should preserve excess range and precision, meaning that for some argument types and values of FLT_EVAL_METHOD, an underlying function should be called for a wider type than that of the arguments.) The underlying functions are implemented with the type-generic template machinery. Comparing x <= y && x >= y is sufficient in ISO C to achieve an equality comparison with "invalid" raised for unordered operands (and the results of those two comparisons can also be used to tell whether errno needs to be set). However, some architectures have GCC bugs meaning that unordered comparison instructions are used instead of ordered ones. Thus, a mechanism is provided for architectures to use an explicit call to feraiseexcept to raise exceptions if required. If your architecture has such a bug you should add a fix-fp-int-compare-invalid.h header for it, with a comment pointing to the relevant GCC bug report; if such a GCC bug is fixed, that header's contents should have a __GNUC_PREREQ conditional added so that the workaround can eventually be removed for that architecture.

Add iscanonical.
TS 18661-1 adds an iscanonical classification macro to <math.h>. The motivation for this is decimal floating-point, where some values have both canonical and noncanonical encodings. For IEEE binary interchange formats, all encodings are canonical. For x86/m68k ldbl-96, and for ldbl-128ibm, there are encodings that do not represent any valid value of the type; although formally iscanonical does not need to handle trap representations (and so could just always return 1), it seems useful, and in line with the description in the TS of "representations that are extraneous to the floating-point model" as being non-canonical (as well as "redundant representations of some or all of its values"), for it to detect those representations and return 0 for them. This patch adds iscanonical to glibc. It goes in a header <bits/iscanonical.h>, included under appropriate conditions in <math.h>. The default header version just evaluates the argument (converted to its semantic type, though current GCC will probably discard that conversion and any exceptions resulting from it) and returns 1. ldbl-96 and ldbl-128ibm then have versions of the header that call a function __iscanonicall for long double (the sizeof-based tests will of course need updating for float128 support, like other such type-generic macro implementations). The ldbl-96 version of __iscanonicall has appropriate conditionals to reflect the differences in the m68k version of that format (where the high mantissa bit may be either 0 or 1 when the exponent is 0 or 0x7fff). Corresponding tests for those formats are added as well. Other architectures do not have any new functions added because just returning 1 is correct for all their floating-point formats. Tested for x86_64, x86, mips64 (to test the default macro version) and powerpc. * math/math.h [__GLIBC_USE (IEC_60559_BFP_EXT)]: Include <bits/iscanonical.h>. * bits/iscanonical.h: New file. * math/s_iscanonicall.c: Likewise. * math/Versions (__iscanonicall): New libm symbol at version GLIBC_2.25. * math/libm-test.inc (iscanonical_test_data): New array.

Installed-header hygiene (BZ#20366): stack_t.
sys/ucontext.h unconditionally uses stack_t, and it does not make sense to change that. But signal.h only declares stack_t under __USE_XOPEN_EXTENDED || __USE_XOPEN2K8. The actual definition is already in a bits header, bits/sigstack.h, but that header insists on only being included by signal.h, so we have to change that as well as all of the sys/ucontext.h variants. (Some but not all variants of bits/sigcontext.h, which sys/ucontext.h may also need, had already received this adjustment; for consistency, I made them all the same, even if that's not strictly necessary in some configurations.) bits/sigcontext.h and bits/sigstack.h also all need to receive multiple inclusion guards. * sysdeps/generic/sys/ucontext.h * sysdeps/arm/sys/ucontext.h * sysdeps/i386/sys/ucontext.h * sysdeps/m68k/sys/ucontext.h * sysdeps/mips/sys/ucontext.h * sysdeps/unix/sysv/linux/aarch64/sys/ucontext.h * sysdeps/unix/sysv/linux/alpha/sys/ucontext.h * sysdeps/unix/sysv/linux/arm/sys/ucontext.h * sysdeps/unix/sysv/linux/hppa/sys/ucontext.h * sysdeps/unix/sysv/linux/ia64/sys/ucontext.h * sysdeps/unix/sysv/linux/m68k/sys/ucontext.h * sysdeps/unix/sysv/linux/mips/sys/ucontext.h * sysdeps/unix/sysv/linux/nios2/sys/ucontext.h * sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h * sysdeps/unix/sysv/linux/s390/sys/ucontext.h * sysdeps/unix/sysv/linux/sh/sys/ucontext.h * sysdeps/unix/sysv/linux/sparc/sys/ucontext.h * sysdeps/unix/sysv/linux/tile/sys/ucontext.h * sysdeps/unix/sysv/linux/x86/sys/ucontext.h: Include both bits/sigcontext.h and bits/sigstack.h.

Add femode_t functions.
TS 18661-1 defines a type femode_t to represent the set of dynamic floating-point control modes (such as the rounding mode and trap enablement modes), and functions fegetmode and fesetmode to manipulate those modes (without affecting other state such as the raised exception flags) and a corresponding macro FE_DFL_MODE. This patch series implements those interfaces for glibc. This first patch adds the architecture-independent pieces, the x86 and x86_64 implementations, and the <bits/fenv.h> and ABI baseline updates for all architectures so glibc keeps building and passing the ABI tests on all architectures. Subsequent patches add the fegetmode and fesetmode implementations for other architectures. femode_t is generally an integer type - the same type as fenv_t, or as the single element of fenv_t where fenv_t is a structure containing a single integer (or the single relevant element, where it has elements for both status and control registers) - except where architecture properties or consistency with the fenv_t implementation indicate otherwise. FE_DFL_MODE follows FE_DFL_ENV in whether it's a magic pointer value (-1 cast to const femode_t *), a value that can be distinguished from valid pointers by its high bits but otherwise contains a representation of the desired register contents, or a pointer to a constant variable (the powerpc case; __fe_dfl_mode is added as an exported constant object, an alias to __fe_dfl_env). Note that where architectures (that share a register between control and status bits) gain definitions of new floating-point control or status bits in future, the implementations of fesetmode for those architectures may need updating (depending on whether the new bits are control or status bits and what the implementation does with previously unknown bits), just like existing implementations of <fenv.h> functions that take care not to touch reserved bits may need updating when the set of reserved bits changes. (As any new bits are outside the scope of ISO C, that's just a quality-of-implementation issue for supporting them, not a conformance issue.) As with fenv_t, femode_t should properly include any software DFP rounding mode (and for both fenv_t and femode_t I'd consider that fragment of DFP support appropriate for inclusion in glibc even in the absence of the rest of libdfp; hardware DFP rounding modes should already be included if the definitions of which bits are status / control bits are correct). Tested for x86_64, x86, mips64 (hard float, and soft float to test the fallback version), arm (hard float) and powerpc (hard float, soft float and e500).

Add fetestexceptflag.

Almost all architectures save exception state in such a way that it can be directly ANDed with exception flag bits, so rather than having lots of fetestexceptflag implementations that all do the same thing, the math/ implementation is made to use this generic logic (which is also OK in the fallback case where FE_ALL_EXCEPT is zero). The only architecture that seems to need anything different is s390. (fegetexceptflag and fesetexceptflag use abbreviated filenames fgetexcptflg.c and fsetexcptflg.c. Because we are no longer concerned by 14-character filename limits, fetestexceptflag uses the obvious filename fetestexceptflag.c.) The NEWS entry is intended to be expanded along the lines given in <https://sourceware.org/ml/libc-alpha/2016-08/msg00356.html> when fegetmode and fesetmode are added.

Add fesetexcept.
TS 18661-1 defines an fesetexcept function for setting floating-point exception flags without the side-effect of causing enabled traps to be taken. This patch series implements this function for glibc. The present patch adds the fallback stub implementation, x86 and x86_64 implementations, documentation, tests and ABI baseline updates. The remaining patches, some of them untested, add implementations for other architectures. The implementations generally follow those of the fesetexceptflag function. As for fesetexceptflag, the approach taken for architectures where setting flags causes enabled traps to be taken is to set the flags (and potentially cause traps) rather than refusing to set the flags and returning an error. Since ISO C and TS 18661 provide no way to enable traps, this is formally in accordance with the standards. The NEWS entry should be considered a placeholder, since this patch series is intended to be followed by further such series adding other TS 18661-1 features, so that the NEWS entry would end up looking more like * New <fenv.h> features from TS 18661-1:2014 are added to libm: the fesetexcept, fetestexceptflag, fegetmode and fesetmode functions, the femode_t type and the FE_DFL_MODE macro. with hopefully more such entries for other features, rather than having an entry for a single function in the end. I believe we have consensus for adding TS 18661-1 interfaces as per <https://sourceware.org/ml/libc-alpha/2016-06/msg00421.html>.

Minimize sysdeps code involved in defining major/minor/makedev.
Presently sys/sysmacros.h is entirely defined in sysdeps. This would mean that the deprecation logic coming up in the next patch would have to be written twice (in generic/ and unix/sysv/linux/). To avoid that, hoist all but the unavoidably system-dependent logic to misc/, leaving a bits/ header behind. This also promotes the Linux-specific encoding of dev_t, which accommodates 32-bit major and minor numbers in a 64-bit dev_t, to generic, as glibc's dev_t is always 64 bits wide. The former Linux implementation used inline functions to avoid evaluating arguments more than once. After this change, all platforms use inline functions, which means that three new symbols are added to the generic ABI. (These symbols are in the user namespace, which is how they have always been on Linux. They begin with "gnu_dev_", so collisions with user code are pretty unlikely.) New ports henceforth need only provide a bits/sysmacros.h defining internal macros __SYSMACROS_{DECLARE,DEFINE}_{MAJOR,MINOR,MAKEDEV}. This is only necessary if the kernel encoding is incompatible with the now-generic encoding (for instance, it would be necessary for FreeBSD). While I was at it, I added a basic round-trip test for these functions. * sysdeps/generic/sys/sysmacros.h: Delete file. * sysdeps/unix/sysv/linux/makedev.c: Delete file. * sysdeps/unix/sysv/linux/sys/sysmacros.h: Move file ... * bits/sysmacros.h: ... here; this encoding is now the generic encoding. Now defines only the following macros: __SYSMACROS_DECLARE_MAJOR, __SYSMACROS_DEFINE_MAJOR, __SYSMACROS_DECLARE_MINOR, __SYSMACROS_DEFINE_MINOR, __SYSMACROS_DECLARE_MAKEDEV, __SYSMACROS_DEFINE_MAKEDEV. * misc/sys/sysmacros.h, misc/makedev.c: New files that use bits/sysmacros.h and the above new macros to generate the public implementations of major, minor, and makedev. * misc/tst-makedev.c: New test. * include/sys/sysmacros.h: New wrapper. * misc/Makefile (headers): Add sys/sysmacros.h, bits/sysmacros.h.

Add nextup and nextdown math functions
TS 18661 adds nextup and nextdown functions alongside nextafter to provide support for float128 equivalent to it. This patch adds nextupl, nextup, nextupf, nextdownl, nextdown and nextdownf to libm before float128 support. The nextup functions return the next representable value in the direction of positive infinity and the nextdown functions return the next representable value in the direction of negative infinity. These are currently enabled as GNU extensions. |

Revert {send,sendm,recv,recvm}msg conformance changes
After some discussion in libc-alpha about this POSIX compliance fix, I see that GLIBC should indeed revert back to previous definition of msghdr and cmsghdr and implementation of sendmsg, recvmsg, sendmmsg, recvmmsg due some reasons: * The possible issue where the syscalls wrapper add the compatibility layer is quite limited in scope and range. And kernel current also add some limits to the values on the internal msghdr and cmsghdr fields: - msghdr::msg_iovlen larger than UIO_MAXIOV (1024) returns EMSGSIZE. - msghdr::msg_controllen larger than INT_MAX returns ENOBUFS. * There is a small performance hit for recvmsg/sendmsg/recmmsg which is neglectable, but it is a big hit for sendmmsg since now instead of calling the syscall for the packed structure, GLIBC is calling multiple sendmsg. This defeat the very existence of the syscall. * It currently breaks libsanitizer build on GCC [1] (I fixed on compiler-rt). However the fix is incomplete because it does add any runtime check since libsanitizer currently does not have any facility to intercept symbols with multiple version [2]. This, along with incorret dlsym/dlvsym return for versioned symbol due another bug [3], makes hard to interpose versioned symbols. Also, current approach of fixing GCC PR#71445 leads to half-baked solutions without versioned symbol interposing. This patch basically reverts commits |

Bug 20198: quick_exit should not call destructors.
In C++11 18.5.12 says "Objects shall not be destroyed as a result of calling quick_exit." In C11 quick_exit is silent about thread object destruction. Therefore to make glibc C++ compliant we do not call any thread local destructors. A new regression test verifies the fix. I will note that C++11 18.5.3 makes it clear that C++ defines additional requirements for _Exit() to prevent it from executing destructors. Given that the point of _Exit() is to terminate the process immediately it makes sense the C and C++ should line up and avoid calling destructors. No failures. New regtest passes. |

network: recvmmsg and sendmmsg standard compliance (BZ#16919)
POSIX specifies that both msghdr::msg_iovlen and msghdr::msg_controllen to be of size int and socklen_t respectively, however Linux implements it as a size_t. So for 64-bits architecture where sizeof of size_t is larger than socklen_t, both sendmmsg and recvmmsg need to adjust the mmsghdr::msg_hdr internal fields before issuing the syscall itself. This patch fixes it by operating on the padding if it the case. For recvmmsg, the most straightfoward case, only zero padding the fields is suffice. However, for sendmmsg, where adjusting the buffer is out of the contract (since it may point to a read-only data), the function is rewritten to use sendmsg instead (which from previous patch allocates a temporary msghdr to operate on). Also for 64-bit ports that requires it, a new recvmmsg and sendmmsg compat version is created (which uses size_t for both cmsghdr::cmsg_len and internal Tested on x86_64, i686, aarch64, armhf, and powerpc64le. * sysdeps/unix/sysv/linux/Makefile [$(subdir) = socket] (sysdep_routines): Add oldrecvmmsg and oldsendmmsg. * sysdeps/unix/sysv/linux/aarch64/libc.abilist: Add recvmmsg and sendmmsg. * sysdeps/unix/sysv/linux/alpha/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/ia64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/libc.abilist: Likewise. * sysdeps/sysv/linux/powerpc/powerpc64/libc-le.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/oldrecvmmsg.c: New file. * sysdeps/unix/sysv/linux/oldsendmmsg.c: Likewise. * sysdeps/unix/sysv/linux/recvmmsg.c (__recvmmsg): Adjust msghdr iovlen and controllen fields to adjust to POSIX specification. * sysdeps/unix/sysv/linux/sendmmsg.c (__sendmmsg): Likewise. |

network: recvmsg and sendmsg standard compliance (BZ#16919)
POSIX specifies that both msghdr::msg_iovlen and msghdr::msg_controllen to be of size int and socklen_t respectively. However Linux defines it as both size_t and for 64-bit it requires some adjustments to make the functions standard compliance. This patch fixes it by creating a temporary header and zeroing the pad fields for 64-bits architecture where size of size_t exceeds the size of the int. Also the new recvmsg and sendmsg implementation is only added on libc, with libpthread only containing a compat symbol.

Fix clone (CLONE_VM) pid/tid reset (BZ#19957)
As discussed in libc-alpha [1] current clone with CLONE_VM (without CLONE_THREAD set) will reset the pthread pid/tid fields to -1. The issue is since memory is shared between the parent and child it will clobber parent's cached pid/tid leading to internal inconsistencies if the value is not restored. And even it is restored it may lead to racy conditions when between set/restore a thread might invoke pthread function that validate the pthread with INVALID_TD_P/INVALID_NOT_TERMINATED_TD_P and thus get wrong results. As stated in BZ19957, previously reports of this behaviour was close with EWONTFIX due the fact usage of clone outside glibc is tricky since glibc requires consistent internal pthread, while using clone directly may not provide it. However since now posix_spawn uses clone (CLONE_VM) to fixes various issues related to previous vfork usage this issue requires fixing. The vfork implementation also does something similar, but instead it negates and restores only the *pid* field and functions that might access its value know to handle such case (getpid, raise and pthread ones that uses INVALID_TD_P/INVALID_NOT_TERMINATED_TD_P macros that check only *tid* field). Also vfork does not call __clone directly, instead calling either __NR_vfork or __NR_clone directly. So this patch removes this clone behavior by avoiding setting the pthread pid/tid field for CLONE_VM. There is no need to check for CLONE_THREAD, since the minimum supported kernel in all architecture implies that CLONE_VM must be used with CLONE_THREAD, otherwise clone returns EINVAL. Instead of current approach of: int clone(int (*fn)(void *), void *child_stack, int flags, ...) [...] if (flags & CLONE_THREAD) goto do_syscall; pid_t new_value; if (flags & CLONE_VM) new_value = -1; else new_value = getpid (); THREAD_SETMEM (THREAD_SELF, pid, new_value); THREAD_SETMEM (THREAD_SELF, tid, new_value); do_syscall: [...] The new approach uses: int clone(int (*fn)(void *), void *child_stack, int flags, ...) [...] if (flags & CLONE_VM) goto do_syscall; pid_t new_value = getpid (); THREAD_SETMEM (THREAD_SELF, pid, new_value); THREAD_SETMEM (THREAD_SELF, tid, new_value); do_syscall: [...] It also removes the linux tst-getpid2.c test which expects the previous behavior and instead add another clone test. Tested on x86_64, i686, x32, powerpc64le, aarch64, armhf, s390, and s390x. I also did limited check on mips32 and sparc64 (using the new added test). I also got reviews from both m68k, hppa, and tile. So I presume for these architecture the patch works. The fixes for alpha, microblaze, sh, ia64, and nio2 have not been tested.

Adjust kernel-features.h defaults for socket syscalls.
This patch adjusts the defaults for kernel-features.h macros relating to availability of accept4, recvmmsg and sendmmsg. It is not intended to affect which macros end up getting defined in any configuration. At present, all architectures with syscalls for those functions need to define __ASSUME_*_SYSCALL macros; in particular, any new architecture needs its own kernel-features.h file for that purpose, though it may not otherwise need such a header. Those macros are then used together with __ASSUME_SOCKETCALL to define macros for whether the functions in question are available. This patch changes the defaults so that the syscalls are assumed to be available by default with recent-enough kernels, and it is the responsibility of architecture headers to undefine the macros if they are unavailable in supported kernels at least as recent as the version where the architecture-independent functionality was introduced. The __ASSUME_<function> macros are defaulted similarly instead of being defined based on other macros (defining based on other macros would no longer work because the #undefs appear after the generic header is included), so where the syscall being unavailable means the function is unavailable this means the architecture header has to undefine the __ASSUME_<function> macro; this only affects __ASSUME_ACCEPT4 for ia64, as other cases where the syscalls were added late enough to be relevant with current kernel version requirements are all on socketcall architectures. As a consequence, the AArch64 and Nios II kernel-features.h header files are removed, and others simplified. When the minimum kernel version becomes 4.3 or later on all architectures, the syscalls in question can just be assumed unconditionally, permitting further simplification. Tested for x86_64, x86 and powerpc (that installed shared libraries are unchanged by the patch, and testsuite for x86_64 and x86). * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_ACCEPT4_SYSCALL): Define unconditionally.

posix: New Linux posix_spawn{p} implementation
This patch implements a new posix_spawn{p} implementation for Linux. The main difference is it uses the clone syscall directly with CLONE_VM and CLONE_VFORK flags and a direct allocated stack. The new stack and start function solves most the vfork limitation (possible parent clobber due stack spilling). The remaning issue are related to signal handling: 1. That no signal handlers must run in child context, to avoid corrupt parent's state. 2. Child must synchronize with parent to enforce stack deallocation and to possible return execv issues. The first one is solved by blocking all signals in child, even NPTL-internal ones (SIGCANCEL and SIGSETXID). The second issue is done by a stack allocation in parent and a synchronization with using a pipe or waitpid (in case or error). The pipe has the advantage of allowing the child signal an exec error (checked with new tst-spawn2 test). There is an inherent race condition in pipe2 usage for architectures that do not support the syscall directly. In such cases the a pipe plus fctnl is used instead and it may lead to file descriptor leak in parent (as decribed by fcntl documentation). The child process stack is allocate with a mmap with MAP_STACK flag using default architecture stack size. Although it is slower than use a stack buffer from parent, it allows some slack for the compatibility code to run scripts with no shebang (which may use a buffer with size depending of argument list count). Performance should be similar to the vfork default posix implementation and way faster than fork path (vfork on mostly linux ports are basically clone with CLONE_VM plus CLONE_VFORK). The only difference is the syscalls required for the stack allocation/deallocation. It fixes BZ#10354, BZ#14750, and BZ#18433. Tested on i386, x86_64, powerpc64le, and aarch64.

powerpc: Add hwcap/hwcap2/platform data to TCB.
This patch adds a new feature for powerpc. In order to get faster access to the HWCAP/HWCAP2 bits and platform number (i.e. for implementing __builtin_cpu_is () / __builtin_cpu_supports () in GCC) without the overhead of reading from the auxiliary vector, we now reserve space for them in the TCB. This is an ABI change for GLIBC 2.23. A new versioned symbol '__parse_hwcap_and_convert_at_platform' is available to get the data from the auxiliary vector and parse it, and store it for later use in the TLS initialization code. This function is called very early (in _dl_sysdep_start () via DL_PLATFORM_INFO for the dynamic linking case, and in __libc_start_main () for the static linking case) to make sure the data is available at the time of TLS initialization. * sysdeps/powerpc/Makefile (sysdep-dl-routines): Add hwcapinfo.

Rename localedir to complocaledir (bug 14259).
In preparation to fix the --localedir configure argument we must move the existing conflicting definition of localedir to a more appropriate name. Given that all current internal uses of localedir relate to the compiled locales we rename to complocaledir. |

Update <sys/ptrace.h> for Linux 4.3.
This patch updates <sys/ptrace.h> for Linux 4.3, adding PTRACE_O_SUSPEND_SECCOMP and updating the value of PTRACE_O_MASK. Some architectures were missing the older PTRACE_O_EXITKILL, so that was added to the files missing it as well. Tested for x86_64 (testsuite, and that installed shared libraries are unchanged by the patch). * sysdeps/unix/sysv/linux/aarch64/sys/ptrace.h (PTRACE_O_EXITKILL): New value in enum __ptrace_setoptions.

Fix lgamma setting signgam for ISO C (bug 15421).
The lgamma (and likewise lgammaf, lgammal) function wrongly sets the signgam variable even when building for strict ISO C conformance (-std=c99 / -std=c11), although the user may define such a variable and it's only in the implementation namespace for POSIX with XSI extensions enabled. Following discussions starting at <https://sourceware.org/ml/libc-alpha/2013-04/msg00767.html> and <https://sourceware.org/ml/libc-alpha/2015-10/msg00844.html>, it seems that the safest approach for fixing this particular issue is for signgam to become a weak alias for a newly exported symbol __signgam, with the library functions only setting __signgam, at which point static linker magic will preserve the alias for newly linked binaries that refer to the library's signgam rather than defining their own, while breaking the alias for programs that define their own signgam, with new symbol versions for lgamma functions and with compat symbols for existing binaries that set both signgam and __signgam. This patch implements that approach for the fix. signgam is made into a weak alias. The four symbols __signgam, lgamma, lgammaf, lgammal get new symbol versions at version GLIBC_2.23, with the existing versions of lgamma, lgammaf and lgammal becoming compat symbols. When the compat versions are built, gamma, gammaf and gammal are aliases for the compat versions (i.e. always set signgam); this is OK as they are not ISO C functions, and avoids adding new symbol versions for them unnecessarily. When the compat versions are not built (i.e. for static linking and for future glibc ports), gamma, gammaf and gammal are aliases for the new versions that set __signgam. The ldbl-opt versions are updated accordingly. The lgamma wrappers are adjusted so that the same source files, included from different files with different definitions of USE_AS_COMPAT, can build either the new versions or the compat versions. Similar changes are made to the ia64 versions (untested). Tests are added that the lgamma functions do not interfere with a user variable called signgam for ISO C, with various choices for the size of that variable, whether it is initialized, and for static and dynamic linking. The conformtest whitelist entry is removed as well. Tested for x86_64, x86, mips64 and powerpc, including looking at objdump --dynamic-syms output to make sure the expected sets of symbols were aliases. Also spot-tested that a binary built with old glibc works properly (i.e. gets signgam set) when run with new glibc. [BZ #15421] * sysdeps/ieee754/s_signgam.c (signgam): Rename to __signgam, initialize with 0 and define as weak alias of __signgam. * include/math.h [!_ISOMAC] (__signgam): Declare. * math/Makefile (libm-calls): Add w_lgamma_compat.

powerpc: Spinlock optimization and cleanup
This patch optimizes powerpc spinlock implementation by: * Use the correct EH hint bit on the larx for supported ISA. For lock acquisition, the thread that acquired the lock with a successful stcx does not want to give away the write ownership on the cacheline. The idea is to make the load reservation "sticky" about retaining write authority to the line. That way, the store that must inevitably come to release the lock can succeed quickly and not contend with other threads issuing lwarx. If another thread does a store to the line (false sharing), the winning thread must give up write authority to the proper value of EH for the larx for a lock acquisition is 1. * Increase contented lock performance by up to 40%, and no measurable impact on uncontended locks on P8. Thanks to Adhemerval Zanella who did most of the work. I've run some tests, and addressed some minor feedback. * sysdeps/powerpc/nptl/pthread_spin_lock.c (pthread_spin_lock): Add lwarx hint, and use macro for acquire instruction. * sysdeps/powerpc/nptl/pthread_spin_trylock.c (pthread_spin_trylock): Likewise. * sysdep/unix/sysv/linux/powerpc/pthread_spin_unlock.c: Move to ... * sysdeps/powerpc/nptl/pthread_spin_unlock.c: ... here, and update to use new atomic macros. |

powerpc: More elision improvements
__lll_trylock_elision sets the adapt_count variable too aggressively, and incorrectly on persistent aborts. Taking a cue from s390, adapt_count is only updated if the lock is locked, or a persistent failure occurs. In addition, the abort codes have been renumbered and refactored for clarity. As it stands, glibc only cares if the abort is persistent or not. All aborts are now persistent, excepting a busy lock. This includes changing _ABORT_NESTED_TRYLOCK into a persistent abort. * sysdeps/unix/sysv/linux/powerpc/elision-trylock.c (__lll_trylock_elision): Fix setting of adapt_count. * sysdeps/unix/sysv/linux/powerpc/htm.h (_ABORT_PERSISTENT): Define to clarify persistent aborts.

The new format lists the version on each line, as in: VERSION SYMBOL TYPE [VALUE] This makes it easier to process the files with line-oriented tools. The abilist files were converted with this awk script: /^[^ ]/ { version = $1 } /^ / { print version, substr($0, 2) } And sorted under the "C" locale with sort. |

Add LFS support for fts functions (bug 11460)
fts didn't have large-file support yet and fts.h had an #error preventing usage when _FILE_OFFSET_BITS was set. This required nasty workarounds for programs using fts with LFS. This patch implements LFS support for fts by adding FTS64 and FTENT64 variants plus fts64 functions. Which are simple aliases for 64bit off_t arches.

Convert 231 sysdeps function definitions to prototype style.
This mostly automatically-generated patch converts 231 sysdeps function definitions in glibc from old-style K&R to prototype-style. For __aio_sigqueue and __gai_sigqueue I had to add internal_function to the definitions as noted by Florian in <https://sourceware.org/ml/libc-alpha/2015-10/msg00595.html> to keep the functions compiling on x86 after conversion to prototype definitions. Otherwise, the patch is automatically generated with all the same exclusions and caveats as in <https://sourceware.org/ml/libc-alpha/2015-10/msg00594.html> except that it's a patch for sysdeps files. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch).

powerpc: Optimize lock elision for pthread_mutex_t
With TLE enabled, the adapt count variable update incurs an 8% overhead before entering the critical section of an elided mutex. Instead, if it is done right after leaving the critical section, this serialization can be avoided. This alters the existing behavior of __lll_trylock_elision as it will only decrement the adapt_count if it successfully acquires the lock. * sysdeps/unix/sysv/linux/powerpc/elision-lock.c (__lll_lock_elision): Remove adapt_count decrement... * sysdeps/unix/sysv/linux/powerpc/elision-trylock.c (__lll_trylock_elision): Likewise. * sysdeps/unix/sysv/linux/powerpc/elision-unlock.c (__lll_unlock_elision): ... to here.

Add INLINE_SYSCALL_ERROR_RETURN_VALUE
For ia32 PIC, the first thing of many syscalls does is to call __x86.get_pc_thunk.reg to load PC into reg in case there is an error, which is required for setting errno. In most cases, there are no errors. But we still call __x86.get_pc_thunk.reg. This patch adds INLINE_SYSCALL_ERROR_RETURN_VALUE so that i386 can optimize setting errno by branching to the internal __syscall_error without PLT.

powerpc: Fix tabort usage in syscalls
Fix usage of tabort in generated syscalls. r0 has special meaning when used with this instruction, thus it will not generate persistent errors, nor return an error code. This mitigates poor CPU usage when performing elided critical sections. Additionally, transactions should be aborted when entering a user invoked syscall.

Remove __ASSUME_IPC64
PowerPC has always used __IPC_64 like most other architectures, which means that __ASSUME_IPC64 can be always true. Also, all other architecture implementations that use the ipc syscall are effectively identical to the generic version and can be removed. |

libio: fmemopen rewrite to POSIX compliance
This patch added a new fmemopen version, for glibc 2.22, that aims to be POSIX complaint. It fixes some long-stading glibc fmemopen issues, such as: * it changes the way fseek with SEEK_END works on fmemopen to seek relative to buffer size instead of first '\0'. This is default mode and 'b' opening mode does not change internal behavior (bz#6544). * fix apending opening mode to use as start position either first null byte of len specified in function call (bz#13152 and #13151). * remove binary option 'b' and internal different handling (bz#12836) * fix seek/SEE_END with negative values (bz#14292). A compatibility symbol is provided to with old behavior for older symbols version (2.2.5). * include/stdio.h (fmemopen): Remove hidden prototype. (__fmemopen): Add new hidden prototype. * libio/Makefile: Add oldfmemopen object. * libio/Versions [GLIBC_2.22]: Add new fmemopen symbol. * libio/fmemopen.c (__fmemopen): Function rewrite to be POSIX compliance. * libio/oldfmemopen.c: New file: old fmemopen implementation for symbol compatibility. * stdio-common/Makefile [tests]: Add new tst-fmemopen3. * stdio-common/psiginfo.c [psiginfo]: Call __fmemopen instead of fmemopen. * stdio-common/tst-fmemopen3.c: New file: more fmemopen tests, focus on append and read mode. * sysdeps/unix/sysv/linux/aarch64/libc.abilist [GLIBC_2.22]: Add fmemopen. * sysdeps/unix/sysv/linux/alpha/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/arm/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/i386/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/ia64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/m68k/m680x0/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/microblaze/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/fpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/nofpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/sh/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/hppa/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/nios2/libc.abilist [GLIBC_2.22]: Likewise. |

nptl: Rewrite cancellation macros
This patch changes the way cancellation entrypoints are defined to instead call the macro SYSCALL_CANCEL. An usual cnacellation definition is defined as: if (SINGLE_THREAD_P) return INLINE_SYSCALL (syscall, NARGS, args...) int oldtype = LIBC_CANCEL_ASYNC (); return INLINE_SYSCALL (syscall, NARGS, args...) LIBC_CANCEL_RESET (oldtype); And it is rewrited as just: SYSCALL_CANCEL (syscall, args...) The idea is to remove LIBC_CANCEL_ASYNC/LIBC_CANCEL_RESET explicit usage.

powerpc: setcontext.S uses power6 mtfsf when not supported [BZ #18116]
The attached patch fixes a glibc build failure with gcc 5 on powerpc64le caused by a recent change in gcc where the compiler defines the _ARCH_PWR6 macro when processing assembly files but doesn't invoke the assembler in the corresponding machine mode (unless it has been explicitly configured to target POWER 6 or later). A bug had been filed with gcc for this (65341) but was closed as won't fix. Glibc relies on the _ARCH_PWR6 macro in a few .S files to make use of Power ISA 2.5 instructions (specifically, the four-argument form of the mtfsf insn). A similar problem had occurred in the past (bug 10118) but the fix that was committed for it didn't anticipate this new problem. |

Consolidate gettimeofday across aarch64/s390/tile
This patch removes the architecture specific gettimeofday implementation to use the vDSO symbol and consolidate it on a common Linux one. Similar to clock_gettime and clock_getres vDSO implementation, each port that supports gettimeofday through vDSO should just implement INLINE_VSYSCALL to access the symbol and define HAVE_{GETTIME,GETRES}_VSYSCAL as 1. |

Consolidate vDSO macros and usage
This patch consolidate the Linux vDSO define and usage across all ports that uses it. The common vDSO definitions and calling through {INLINE/INTERNAL}_VSYSCALL macros are moved to a common header sysdep-vdso.h and vDSO name declaration and prototype is defined using a common macro. Also PTR_{MANGLE,DEMANGLE} is added to ports that does not use them for vDSO calls (aarch64, powerpc, s390, and tile) and thus it will reflect in code changes. For ports that already implement pointer mangling/demangling in vDSO system (i386, x32, x86_64) this patch is mainly a code refactor. Checked on x32, x86_64, x32, ppc64le, and aarch64. |

Remove socket.S implementation
This patch removes the socket.S implementation for all ports and replace it by a C implementation using socketcall. For ports that implement the syscall directly, there is no change. The patch idea is to simplify the socket function implementation that uses the socketcall to be based on C implemetation instead of a pseudo assembly implementation with arch specific parts. The patch then remove the assembly implementatation for the ports which uses socketcall (i386, microblaze, mips, powerpc, sparc, m68k, s390 and sh). I have cross-build GLIBC for afore-mentioned ports and tested on both i386 and ppc32 without regressions. |

powerpc __tls_get_addr call optimization
This patch is glibc support for a PowerPC TLS optimization, inspired by Alexandre Oliva's TLS optimization for other processors, http://www.lsd.ic.unicamp.br/~oliva/writeups/TLS/RFC-TLSDESC-x86.txt In essence, this optimization uses a zero module id in the tls_index GOT entry to indicate that a TLS variable is allocated space in the static TLS area. A special plt call linker stub for __tls_get_addr checks for such a tls_index and if found, returns the offset immediately. The linker communicates the fact that the special __tls_get_addr stub is used by setting a bit in the dynamic tag DT_PPC64_OPT/DT_PPC_OPT. glibc communicates to the linker that this optimization is available by the presence of __tls_get_addr_opt. tst-tlsmod2.so is built with -Wl,--no-tls-get-addr-optimize for tst-tls-dlinfo, which otherwise would fail since it tests that no static tls is allocated. The ld option --no-tls-get-addr-optimize has been available since binutils-2.20 so doesn't need a configure test. * NEWS: Advertise TLS optimization. * elf/elf.h (R_PPC_TLSGD, R_PPC_TLSLD, DT_PPC_OPT, PPC_OPT_TLS): Define.

Fix posix_spawn getrlimit64 namespace (bug 17991).
posix_spawn (a standard POSIX function) brings in a use of getrlimit64 (not a standard POSIX function). This patch fixes this by using __getrlimit64 and making getrlimit64 a weak alias. This is more complicated than some such changes because of files that define getrlimit64 in their own way using symbol versioning after including the main sysdeps/unix/sysv/linux/getrlimit64.c with a getrlimit macro defined. There are various existing patterns for such cases in glibc; the one I've used here is that a getrlimit64 macro disables the weak_alias / libc_hidden_weak calls, leaving it to the including file to define the getrlimit64 name in whatever way is appropriate. Tested for x86_64 and x86 that installed stripped shared libraries are unchanged by this patch. [BZ #17991] * include/sys/resource.h (__getrlimit64): Declare.

Fix semaphore destruction (bug 12674).
This commit fixes semaphore destruction by either using 64b atomic operations (where available), or by using two separate fields when only 32b atomic operations are available. In the latter case, we keep a conservative estimate of whether there are any waiting threads in one bit of the field that counts the number of available tokens, thus allowing sem_post to atomically both add a token and determine whether it needs to call futex_wake.

powerpc: abort transaction in syscalls
Linux kernel powerpc documentation states issuing a syscall inside a transaction is not recommended and may lead to undefined behavior. It also states syscalls does not abort transactoin neither they run in transactional state. To avoid side-effects being visible outside transactions, GLIBC with lock elision enabled will issue a transaction abort instruction just before all syscalls if hardware supports hardware transactions. |

This patch adds support for lock elision using ISA 2.07 hardware transactional memory instructions for pthread_mutex primitives. Similar to s390 version, the for elision logic defined in 'force-elision.h' is only enabled if ENABLE_LOCK_ELISION is defined. Also, the lock elision code should be able to be built even with a compiler that does not provide HTM support with builtins. However I have noted the performance is sub-optimal due scheduling pressures. |

Run check-localpltk/textrel/execstack over ld.so.
For maximum paranoia we run ld.so through the normal set of tests for all of the shared libraries. This includes running ld.so through check-localplt, check-textrel, and check-execstack. While none of these should trigger any failures given the way ld.so is built, it might possibly fail if a developer does something wrong. This paranoia was triggered by a discussion over the use of __strcpy vs. strcpy [1] and if the symbol could leak and use the libc.so version. The check-localplt test fails right away because localplt.data needs updating for all arches. By default we add 6 new symbols: __tls_get_addr, __libc_memalign, malloc, calloc, realloc and free. Other machines like i386, power, and s390 require some different symbol sets e.g. ___tls_get_addr vs. __tls_get_addr for i386.

Move powerpc64 pread/pwrite definitions to syscalls.list (bug 14138).
Concluding the move of syscall definitions to syscalls.list, where the removal of support for old kernel versions has made this possible, this patch removes C definitions of pread, pread64, pwrite and pwrite64 for powerpc64.

Support and use mixed compat/non-compat aliases in syscalls.list.
This patch enables syscalls.list entries to specify both compat and non-compat symbol versions for the same syscall definition, making use of this for setrlimit / chown / lchown where the inability to specify such aliases showed up in the course of work on bug 14138. The change to make-syscalls.sh is minimal: adding a SHARED conditional on the compat_symbol calls. It remains the case that if a compat symbol version is specified, the syscall is only built for the shared library at all if an explicit symbol version is given for a non-compat symbol (so it's necessary to specify "lchown@@GLIBC_2.0 chown@GLIBC_2.0" rather than just "lchown chown@GLIBC_2.0"). It also remains the case, as already commented in make-syscalls.sh, that no SHLIB_COMPAT conditionals are generated, so there would be problems if the same syscalls.list file, with compat symbols, were used for both configurations that should have those symbols and configurations for which they should be conditioned out with SHLIB_COMPAT. Tested for x86. * sysdeps/unix/make-syscalls.sh (emit_weak_aliases): Condition compat_symbol calls on [SHARED]. * sysdeps/unix/sysv/linux/powerpc/lchown.S: Remove file. * sysdeps/unix/sysv/linux/i386/syscalls.list (oldsetrlimit): Remove.

Move some chown / lchown / fchown definitions to syscalls.list (bug 14138).
Continuing the move of syscall definitions to syscalls.list, where the removal of support for old kernel versions has made this possible, this patch moves various definitions of chown, lchown and fchown. In most cases the need for special syscalls.list entries (rather than existing generic ones) is because these architectures use chown32, lchown32 and fchown32 as syscall names. Some architectures also have symbol versioning compatibility for older versions of chown having been equivalent to lchown. In the case of powerpc, chown.c (providing the chown@@GLIBC_2.1 default version) is replaced by a syscalls.list entry (for powerpc32; powerpc64 has no need for this because of its more recent minimum symbol version, so can just use the entry in sysdeps/unix/syscalls.list), but lchown.S is left as-is because it provides the compat version of chown as an actual alias for __lchown, which is not yet supported by syscalls.list. This file can be removed once such aliases are supported in syscalls.list.

Remove shlib-versions entries redundant with DEFAULT entries.
When a shlib-versions file has a DEFAULT line, it's not necessary to specify the same default minimum symbol version on the lines for individual libraries. If those lines otherwise duplicate the default SONAME for the library in question, they can be removed completely. This patch makes such cleanups: version entries for ld.so are removed (leaving just the definition of the architecture-specific dynamic linker name) and entries for libpthread are removed completely (since the default is libpthread.so.0). Tested for x86_64 that the installed shared libraries are unchanged by this patch. There are various architectures (hppa, ia64, mips, sh, sparc64) that define minimum symbol versions (or in the case of mips, omission of symbol versions) only for particular libraries without a DEFAULT line. None of these are equivalent to something simpler with a DEFAULT line because all have some other libraries, not explicitly mentioned, with symbol versions that would be omitted were such a line used. In the mips case I'm pretty sure it was a mistake not to omit the 2.1 symbols for libthread_db; for the others I don't know if it was a mistake or deliberate that some symbols in various libraries have 2.0 or 2.1 versions despite other libraries having a 2.2 minimum. This concludes the shlib-versions cleanups I'm aware of. * sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions: Do not specify symbol version for ld.so. Do not include entry for libpthread. * sysdeps/unix/sysv/linux/s390/s390-64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/shlib-versions: Likewise. |

Clean up gnu/lib-names.h generation (bug 14171).
This patch eliminates the mixture of SONAME information in shlib-versions files and SONAME information used to generate gnu/lib-names.h in makefiles, with the information in the makefiles being removed so all this information comes from the shlib-versions files. So that gnu/lib-names.h supports multiple ABIs, it is changed to be generated on the same basis as gnu/stubs.h: when there are multiple ABIs, gnu/lib-names.h is a wrapper header (the same header installed whatever ABI is being built) and separate headers such as gnu/lib-names-64.h contain the substantive contents (only one such header being installed by any glibc build). The rules for building gnu/lib-names.h were moved from Makeconfig to Makerules because they need to come after sysdeps makefiles are included (now that "ifndef abi-variants" is a toplevel conditional on the rules rather than $(abi-variants) being evaluated later inside the commands for a rule). Tested for x86_64 and x86 that the installed shared libraries are unchanged by this patch, and examined the installed gnu/lib-names*.h headers by hand. Also tested the case of a single ABI (where there is just a single header installed, again like stubs.h) by hacking abi-variants to empty for x86_64. [BZ #14171] * Makeconfig [$(build-shared) = yes] ($(common-objpfx)soversions.mk): Don't handle SONAMEs specified in makefiles.

Bug 14138 is followup cleanup after removal of support for old Linux kernel versions: moving syscalls to syscalls.list where the only reason for using C definitions was kernel version conditionals that are no longer present. This patch deals with the case of setrlimit (sysdeps/unix/sysv/linux/i386/setrlimit.c, included by various other architectures). Where needed (where there is also a compat symbol for setrlimit@GLIBC_2.0), new syscalls.list entries are added. Where not needed (where there is no such compat symbol and the minimum symbol version for libc is 2.2 or later), no such entries are added as that in sysdeps/unix/syscalls.list will suffice. Thus arm and sh need no such entries, while m68k and powerpc need entries only in a subdirectory syscalls.list file rather than for all configurations that previously used setrlimit.c. (setrlimit@@GLIBC_2.2 and setrlimit@GLIBC_2.0 are now semantically identical - the new symbol version was about a change of types from signed to unsigned and the former compatibility code for dealing with large unsigned arguments on old kernels is no longer needed or present, having been removed with support for pre-2.4 kernels. However, making the two versions into aliases doesn't work at present: the case of having both default and non-default symbol versions on the same syscalls.list line results in a compat_symbol call in code built for static libc, which doesn't compile. I don't suppose it would be hard to generate SHARED conditionals from make-syscalls.sh to fix this, but in any case this patch doesn't make things any worse, as the functions weren't aliases before the patch either.) Tested for x86, and ran ABI tests for ARM as an example of an architecture where the setrlimit.c file was just removed without adding syscalls.list entries.

Remove configuration name patterns from shlib-versions.
This patch removes the first column (patterns matching configuration names) from shlib-versions, leaving shlib-versions entry selection based purely on sysdeps directories. An implication of this removal is that the default for any non-Linux ports using NPTL will be the same SONAMEs for NPTL libraries as for Linux (as those defaults, previously limited to .*-.*-linux.*, are left in nptl/shlib-versions and nptl_db/shlib-versions). Special host_os handling in configure.ac that was purely for shlib-versions is removed. (The host_os setting is still used for libc-abis - see <https://sourceware.org/ml/libc-alpha/2014-01/msg00375.html> regarding that - but no entries there are affected by this change.) Tested on x86_64 and x86 that the installed shared libraries are unchanged by this patch. * scripts/soversions.awk: Do not handle configuration names. * Makeconfig ($(common-objpfx)soversions.i): Do not pass cpu, vendor and os variables to soversions.awk. * configure.ac: Do not modify gnu-* host_os. * configure: Regenerated * shlib-versions: Remove first column with configuration names. * nptl/shlib-versions: Likewise. * nptl_db/shlib-versions: Likewise. * sysdeps/hppa/shlib-versions: Likewise. * sysdeps/m68k/shlib-versions: Likewise. * sysdeps/mach/hurd/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/aarch64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/alpha/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/arm/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/hppa/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/ia64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/microblaze/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/mips/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sh/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/tile/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/shlib-versions: Likewise. libidn/ChangeLog: * shlib-versions: Remove first column with configuration names. |

Use %ifdef in sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions.
This patch makes sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions use %ifdef conditionals around the different symbol version definitions for big and little endian. (It doesn't actually change the host patterns used for those definitions; the point is to make it possible to remove the first column from shlib-versions by eliminating the last case where it would be harmful for it to be treated as .*-.*-.*.) The conditional is based on the ELFv1/ELFv2 distinction rather than BE/LE, since that's what's already tested in configure and used for the ld.so soname in the Makefiles. (Of course if BE ELFv2 were supported in future, it would get new symbol versions and so need new conditionals.) * sysdeps/unix/sysv/linux/powerpc/powerpc64/configure.ac (HAVE_ELFV2_ABI): AC_DEFINE in ELFv2 case. * sysdeps/unix/sysv/linux/powerpc/powerpc64/configure: Regenerated. * config.h.in (HAVE_ELFV2_ABI): New macro undefine. * sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions: Condition symbol version definitions on [HAVE_ELFV2_ABI]. |

Move architecture-specific shlib-versions entries to sysdeps files.
This patch eliminates another way in which ex-ports and non-ex-ports architectures differ, by moving architecture-specific entries from the top-level shlib-versions file and that in nptl/ to appropriate sysdeps directories. As with my previous patch <https://sourceware.org/ml/libc-alpha/2014-06/msg00949.html>, I do not change the regular expressions used; even where the present expressions seem more general, I believe they are in fact specific to the chosen sysdeps directory, because any port that matches the expression but not the sysdeps directory does not currently exist, and so would use different symbol versions if added in future (and an intended goal of these changes is to eliminate the first column in shlib-versions completely rather than having two different mechanisms in use for system-specific configuration). Tested on x86_64 that this does not change the installed shared libraries. (x86_64 of course does not provide much test coverage for this patch - what should be architecture-specific contents in shlib-versions for x86_64 is currently abi-*-ld-soname Makefile settings, until gnu/lib-names.h is generated more like gnu/stubs.h so those can move back to shlib-versions.) * nptl/shlib-versions: Remove architecture-specific entries. Moved to files in sysdeps. * shlib-versions: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/shlib-versions: New file. * sysdeps/unix/sysv/linux/s390/s390-64/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sh/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/shlib-versions: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/shlib-versions: Likewise. |

Fix powerpc32 __get_clockfreq for non-power4 (bug 17263).
In my powerpc32 testing I've observed misc/test-gettimebasefreq failing. This is a glibc build (soft-float, though that's not relevant here) without any --with-cpu and without any special configuration of the default CPU for GCC either. In particular, it's one not using sysdeps/powerpc/powerpc32/power4/hp-timing.h (although in fact the processor I'm using for testing is POWER4-based), so hp_timing_t is 32-bit not 64-bit. But the VDSO call being used by INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK is generating a 64-bit result (high part in r3, low part in r4). The code extracting that result, however, expects a result of the type hp_timing_t as passed to INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK, meaning that only r3 (= 0) is used and the value in r4 is ignored. This patch fixes this by always using uint64_t as the type in INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK - reflecting the actual ABI (unconditional in the kernel) of that VDSO call. This is the minimal change for this issue - no check for overflow, no change of the type of the timebase_freq variable or the return type of __get_clockfreq to something other than hp_timing_t (such a change would simply move the implicit conversions to the over callers of that function), no change to hp_timing_t itself. Tested for powerpc32 soft float. [BZ #17263] * sysdeps/unix/sysv/linux/powerpc/get_clockfreq.c: Include <stdint.h>. (__get_clockfreq): Use uint64_t instead of hp_timing_t in INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK call. |

PowerPC: Fix termios definitions
This patch fixes the incorrect guard by __USE_MISC of struct winsize and struct termio in powerpc termios header. Current states leads to build failures if the program defines _XOPEN_SOURCE, but not _DEFAULT_SOURCE or either _BSD_SOURCE or _SVID_SOURCE. Without any definition, __USE_MISC will not be defined and neither the struct definitions. This patch copies the default Linux ioctl-types.h by adjusting only the character control field (c_cc) size in struct termio. |

Refactor handling of /lib64 etc. cases, move out of sysdeps/gnu/configure.ac.
This patch continues removing architecture-specific cases from non-architecture-specific files by moving the logic to use directories such as /lib64 out of sysdeps/gnu/configure.ac. A new macro LIBC_SLIBDIR_RTLDDIR is created that sysdeps configure scripts can use to declare the library directories to be used; the logic was previously duplicated in configure fragments for aarch64, mips and x32 as well as in sysdeps/gnu/configure.ac. This macro is used directly in sysdeps/gnu/configure.ac only to provide the /lib default (the logic saying that with --prefix=/usr shared libraries go in /lib not /usr/lib); the architecture cases formerly there are moved into various new or existing configure.ac files. The new macro is also used in the various architecture fragments that already had such logic. In the x32 there was previously a configure fragment, but it was a directly written one without a .ac file; now a .ac file is used there instead to generate configure. Tested x86_64 that the installed shared libraries, and the directory structure of the installation, are unchanged by this patch. There is an old bug report - bug 6441 - about library directories changing after reconfiguring. If this is still applicable - and I haven't attempted to confirm it or review the old patch pointed to in that bug - then this patch should reduce the number of places needing changing in any fix. * aclocal.m4 (LIBC_SLIBDIR_RTLDDIR): New macro. * sysdeps/gnu/configure.ac: Use LIBC_SLIBDIR_RTLDDIR.

Move architecture cases out of sysdeps/unix/sysv/linux/configure.ac.
Continuing the process of making non-ex-ports architectures follow the preferred sysdeps practices followed by ex-ports architectures - that is, putting things in architecture-specific sysdeps files rather than having architecture-specific cases in architecture-independent files - this patch moves architecture cases out of sysdeps/unix/sysv/linux/configure.ac into (new or existing) configure fragments for each architecture. (In the case of the arch_minimum_kernel setting for x32, sysdeps/unix/sysv/linux/x86_64/x32/configure already has such a setting so the setting in sysdeps/unix/sysv/linux/configure.ac was a duplicate that could just be removed - though I haven't tested for x32.) Tested for x86_64 and x86 that the patch causes no changes to the installed shared libraries or ldd (or any part of the installation except for the parts that always change because the files contain timestamps - nscd and static libraries). * sysdeps/unix/sysv/linux/configure.ac: Remove cases for individual architectures. * sysdeps/unix/sysv/linux/configure: Regenerated. * sysdeps/unix/sysv/linux/i386/configure.ac: New file. * sysdeps/unix/sysv/linux/i386/configure: New generated file. * sysdeps/unix/sysv/linux/powerpc/configure.ac (ldd_rewrite_script): Define variable. * sysdeps/unix/sysv/linux/powerpc/configure: Regenerated. * sysdeps/unix/sysv/linux/powerpc/powerpc32/configure.ac: New file. * sysdeps/unix/sysv/linux/powerpc/powerpc32/configure: New generated file. * sysdeps/unix/sysv/linux/s390/configure.ac: New file. * sysdeps/unix/sysv/linux/s390/configure: New generated file. * sysdeps/unix/sysv/linux/sh/configure.ac: New file. * sysdeps/unix/sysv/linux/sh/configure: New generated file. * sysdeps/unix/sysv/linux/sparc/configure.ac: New file. * sysdeps/unix/sysv/linux/sparc/configure: New generated file. * sysdeps/unix/sysv/linux/x86_64/configure.ac: New file. * sysdeps/unix/sysv/linux/x86_64/configure: New generated file. |

Remove __ASSUME_ATFCTS conditionals in sysdeps/unix/sysv/linux/.
This patch cleans up for __ASSUME_ATFCTS now always being true for the supported Linux kernel versions by removing conditional code in sysdeps/unix/sysv/linux. Several fchownat.c files that were only present because of differences in the fallback syscalls used (depending on the architecture-specific names of chown-related syscalls for 32-bit uids) are removed. Files that looks like they could be replaced by syscalls.list entries have the standard "Consider moving to syscalls.list." comment (see bug 14138) added. Conditionals on the relevant __NR_* syscall numbers being defined are also removed, since my analysis indicated that the relevant syscalls are always defined for all relevant kernel versions using any affected file. Much of the removed fallback code had unbounded stack allocations, so this reduces the number of cases to consider for anyone reviewing uses of alloca and VLAs in glibc. There remain tests of __ASSUME_ATFCTS in io/openat.c (to determine whether to define __have_atfcts) and sysdeps/posix/getcwd.c (which also uses __have_atfcts); thus, the definition of __ASSUME_ATFCTS remains in kernel-features.h. The logical condition relevant there is whether openat64_not_cancel_3 is known to work. Hurd doesn't use this version of getcwd at all, so the conditionals in getcwd.c are always true in glibc. However, this code is also used in gnulib. So the best way to deal with the conditionals there may be for gnulib people to deal with merging all relevant changes in both directions between the glibc and gnulib versions of this file, at the end of which the openat conditionals should be in whatever form is best for gnulib, and hardcoded in the _LIBC case to having openat supported. Tested by comparing before-and-after disassembly of installed (stripped) shared libraries, on x86_64 and x86. On x86 the patch made no change to the disassembly; on x86_64, the only changes were in readlinkat, where formerly the return value from the readlinkat syscall was stored in an int variable before being converted to ssize_t for the return, and now the return value is returned directly without truncation to int. I think it's clearly correct not to truncate the return value (although I also think the truncation would not have been a user-visible bug because the kernel would never have returned a value it could have affected). * include/fcntl.h (__atfct_seterrno): Remove prototype.

Add adaptive elision to rwlocks
This patch relies on the C version of the rwlocks posted earlier. With C rwlocks it is very straight forward to do adaptive elision using TSX. It is based on the infrastructure added earlier for mutexes, but uses its own elision macros. The macros are fairly general purpose and could be used for other elision purposes too. This version is much cleaner than the earlier assembler based version, and in particular implements adaptation which makes it safer. I changed the behavior slightly to not require any changes in the test suite and fully conform to all expected behaviors (generally at the cost of not eliding in various situations). In particular this means the timedlock variants are not elided. Nested trylock aborts. |

PowerPC: define _CALL_ELF if compiler does not
This patch makes the configure adds -D_CALL_ELF=1 when compiler does not define _CALL_ELF (versions before powerpc64le support). It cleans up compiler warnings on old compiler where _CALL_ELF is not defined on powerpc64(be) builds. It does by add a new config.make variable for configure-deduced CPPFLAGS and accumulate into that (confix-extra-cppflags). It also generalizes libc_extra_cflags so it accumulates in sysdeps configure fragmenets. |

Complete _BSD_SOURCE / _SVID_source followup cleanup.
This patch completes the headers cleanup consequent on removal of _BSD_SOURCE and _SVID_SOURCE (apart from any subsequent deprecations): * #endif conditionals that referred to BSD or SVID are updated. * Redundant __USE_* tests in cases involving __USE_MISC are removed. This includes cases such as __USE_MISC || __USE_ISOC99, where __USE_MISC is redundant (because __USE_MISC is only ever defined in the default / _DEFAULT_SOURCE / _GNU_SOURCE case, when __USE_ISOC99 is also defined; the same applies to the non-XSI-extended POSIX versions), and cases involving __USE_GNU, where __USE_GNU is redundant (because if __USE_GNU is defined, so are the other __USE_* macros). There may well be other cases of __USE_FOO || __USE_BAR tests that could be simplified because one macro implies the other; this patch only addresses cases involving __USE_MISC.

Combine __USE_BSD and __USE_SVID into __USE_MISC.
This patch cleans up following the obsoletion of _BSD_SOURCE and _SVID_SOURCE by combining __USE_BSD and __USE_SVID into __USE_MISC. The only non-mechanical part of this patch is the changes to features.h; everything else is simple substitution of __USE_MISC for the old macros. Thus, this patch leaves obviously redundant conditionals such as "defined __USE_MISC || defined __USE_MISC", and does not update #endif comments where they referred to BSD or SVID in words instead of the literal macro name. This is intended to facilitate patch review by separating the less mechanical changes from these purely mechanical changes into a separate patch. (I do intend to integrate all the changes from <https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I believe includes all the trailing comment updates, in subsequent patches.)
