Add renameat2 function [BZ #17662]
The implementation falls back to renameat if renameat2 is not available in the kernel (or in the kernel headers) and the flags argument is zero. Without kernel support, a non-zero argument returns EINVAL, not ENOSYS. This mirrors what the kernel does for invalid renameat2 flags. |

Fix Linux fcntl OFD locks for non-LFS architectures (BZ#20251)
This patch fixes the OFD ("file private") locks for architectures that
support non-LFS flock definition (__USE_FILE_OFFSET64 not defined). The
issue in this case is both F_OFD_{GETLK,SETLK,SETLKW} and
F_{SET,GET}L{W}K64 expects a flock64 argument and when using old
F_OFD_* flags with a non LFS flock argument the kernel might interpret
the underlying data wrongly. Kernel idea originally was to avoid using
such flags in non-LFS syscall, but since GLIBC uses fcntl with LFS
semantic as default it is possible to provide the functionality and
avoid the bogus struct kernel passing by adjusting the struct manually
for the required flags.
The idea follows other LFS interfaces that provide two symbols:
1. A new LFS fcntl64 is added on default ABI with the usual macros to
select it for FILE_OFFSET_BITS=64.
2. The Linux non-LFS fcntl use a stack allocated struct flock64 for
F_OFD_{GETLK,SETLK,SETLKW} copy the results on the user provided
struct.
3. Keep a compat symbol with old broken semantic for architectures
that do not define __OFF_T_MATCHES_OFF64_T.
So for architectures which defines __USE_FILE_OFFSET64, fcntl64 will
aliased to fcntl and no adjustment would be required. So to actually
use F_OFD_* with LFS support the source must be built with LFS support
(_FILE_OFFSET_BITS=64).
Also F_OFD_SETLKW command is handled a cancellation point, as for
F_SETLKW{64}.
Checked on x86_64-linux-gnu and i686-linux-gnu.

Remove sysdeps/powerpc/soft-fp directory.
As per <https://sourceware.org/ml/libc-alpha/2014-10/msg00369.html>, there should not be separate sysdeps/<arch>/soft-fp directories when those are used by all configurations that use sysdeps/<arch>, and, more generally, should not be sysdeps/foo/Implies files pointing to a subdirectory foo/bar. sysdeps/powerpc/soft-fp isn't quite such a case, as the Implies files pointing to it are sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/Implies and sysdeps/unix/sysv/linux/powerpc/powerpc32/e500/nofpu/Implies (and indeed there is a different sfp-machine.h used for powerpc64le). However, the same principle applies: there is no need for this directory because sfp-machine.h, the only file in it, can most naturally go in sysdeps/powerpc/nofpu, which is used by exactly the same configurations (and there is a close dependence between the files there and the sfp-machine.h implementation). This patch eliminates the sysdeps/powerpc/soft-fp directory accordingly. Tested with build-many-glibcs.py that installed stripped shared libraries for powerpc configurations are unchanged by this patch. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/Implies: Remove powerpc/soft-fp. * sysdeps/unix/sysv/linux/powerpc/powerpc32/e500/nofpu/Implies: Likewise. * sysdeps/powerpc/soft-fp/sfp-machine.h: Move to .... * sysdeps/powerpc/nofpu/sfp-machine.h: ... here. |

Add narrowing divide functions.
This patch adds the narrowing divide functions from TS 18661-1 to glibc's libm: fdiv, fdivl, ddivl, f32divf64, f32divf32x, f32xdivf64 for all configurations; f32divf64x, f32divf128, f64divf64x, f64divf128, f32xdivf64x, f32xdivf128, f64xdivf128 for configurations with _Float64x and _Float128; __nldbl_ddivl for ldbl-opt. The changes are mostly essentially the same as for the other narrowing functions, so the description of those generally applies to this patch as well. Tested for x86_64, x86, mips64 (all three ABIs, both hard and soft float) and powerpc, and with build-many-glibcs.py. * math/Makefile (libm-narrow-fns): Add div.

Add narrowing multiply functions.
This patch adds the narrowing multiply functions from TS 18661-1 to glibc's libm: fmul, fmull, dmull, f32mulf64, f32mulf32x, f32xmulf64 for all configurations; f32mulf64x, f32mulf128, f64mulf64x, f64mulf128, f32xmulf64x, f32xmulf128, f64xmulf128 for configurations with _Float64x and _Float128; __nldbl_dmull for ldbl-opt. The changes are mostly essentially the same as for the narrowing add functions, so the description of those generally applies to this patch as well. f32xmulf64 for i386 cannot use precision control as used for add and subtract, because that would result in double rounding for subnormal results, so that uses round-to-odd with long double intermediate result instead. The soft-fp support involves adding a new FP_TRUNC_COOKED since soft-fp multiplication uses cooked inputs and outputs. Tested for x86_64, x86, mips64 (all three ABIs, both hard and soft float) and powerpc, and with build-many-glibcs.py. * math/Makefile (libm-narrow-fns): Add mul.

Ignore absolute symbols in ABI tests.
A recent binutils patch <https://sourceware.org/ml/binutils/2018-04/msg00336.html> stops the MIPS linker including the _gp_disp absolute symbol in dynamic symbol tables. With older binutils, it is included for MIPS o32 (despite the use of symbol versioning), and this means that all the ABI test baselines for MIPS o32 include "_gp_disp _gp_disp A". This symbol is not meaningfully part of the ABI for shared libraries, since it always has to be resolved at static link time to the local definition for the linked object. All the other absolute symbols in ABI test baselines are the names of symbol versions. I don't think the mere existence of a symbol version with a given name - as opposed to the contents of that version if nonempty - is part of the ABI either. Thus, this patch allows the ABI tests to pass both before and after the binutils change by changing abilist.awk not to include absolute symbols in its output, and changing the baselines accordingly. Tested for x86_64, and with build-many-glibcs.py. * scripts/abilist.awk: Ignore absolute symbols. * sysdeps/mach/hurd/i386/ld.abilist: Remove absolute symbols. *

Consolidate Linux readahead implementation
This patch consolidate Linux readahead implementation on generic
sysdeps/unix/sysv/linux/readahead.c one. The changes are:
- Assume __NR_readahead existence with current minimum kernel of 3.2
for all architectures.
- Use INLINE_SYSCALL_CALL, __ALIGNMENT_ARG, and SYSCALL_LL64 to pass
the 64 bit offset. This allows architectures with different abis
to use the same implementation.
- Remove arch-specific readahead implementations.
Checked on x86_64-linux-gnu and i686-linux-gnu.

Consolidate alphasort{64} and versionsort{64} implementation
This patch consolidates both alphasort{64} and versionsort{64}
implementation on just the default dirent/alphasort{64}c and
dirent/versionsort{64} respectively. It changes the logic
to follow the conventions used on other code consolidation:
* the non-LFS variant is only built for _DIRENT_MATCHES_DIRENT64 being 0.
* the LFS variant is always built and aliased to getdents for ABIs
that define _DIRENT_MATCHES_DIRENT64 to 1.
Also on Linux the compat symbol for old non-LFS dirent64 definition
requires a platform-specific scandir64.c. For powerpc32 and sparcv9
it requires to add specific arch-implementation to override the
generic Linux one because neither ABI exports an compat symbol for
non-LFS alphasort64 and versionsort64 variant. It is most likely a
bug and it is also not one that can be fixed (in that there would be
existing binaries expecting both meanings of that symbol at its single
existing version, with binaries expecting the new meaning probably much
more common than those expecting the original meaning of that symbol at
that version).
Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu,

Consolidate scandir{at}{64} implementation
This patch consolidates scandir{at}{64} implementation on just
the default dirent/scandir{at}{64}{_r}.c ones. It changes the logic
to follow the conventions used on other code consolidation:
* scandir{at} is only built for _DIRENT_MATCHES_DIRENT64 being 0.
* scandir{at}{64} is always built and aliased to getdents for ABIs
that define _DIRENT_MATCHES_DIRENT64 to 1.
Also on Linux the compat symbol for old non-LFS dirent64 definition
requires a platform-specific scandir64.c.
Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu,
sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu, and
powerpc64le-linux-gnu.

Add narrowing subtract functions.
This patch adds the narrowing subtract functions from TS 18661-1 to glibc's libm: fsub, fsubl, dsubl, f32subf64, f32subf32x, f32xsubf64 for all configurations; f32subf64x, f32subf128, f64subf64x, f64subf128, f32xsubf64x, f32xsubf128, f64xsubf128 for configurations with _Float64x and _Float128; __nldbl_dsubl for ldbl-opt. The changes are essentially the same as for the narrowing add functions, so the description of those generally applies to this patch as well.

Add narrowing add functions.
This patch adds the narrowing add functions from TS 18661-1 to glibc's libm: fadd, faddl, daddl, f32addf64, f32addf32x, f32xaddf64 for all configurations; f32addf64x, f32addf128, f64addf64x, f64addf128, f32xaddf64x, f32xaddf128, f64xaddf128 for configurations with _Float64x and _Float128; __nldbl_daddl for ldbl-opt. As discussed for the build infrastructure patch, tgmath.h support is deliberately deferred, and FP_FAST_* macros are not applicable without optimized function implementations. Function implementations are added for all relevant pairs of formats (including certain cases of a format and itself where more than one type has that format). The main implementations use round-to-odd, or a trivial computation in the case where both formats are the same or where the wider format is IBM long double (in which case we don't attempt to be correctly rounding). The sysdeps/ieee754/soft-fp implementations use soft-fp, and are used automatically for configurations without exceptions and rounding modes by virtue of existing Implies files. As previously discussed, optimized versions for particular architectures are possible, but not included. i386 gets a special version of f32xaddf64 to avoid problems with double rounding (similar to the existing fdim version), since this function must round just once without an intermediate rounding to long double. (No such special version is needed for any other function, because the nontrivial functions use round-to-odd, which does the intermediate computation with the rounding mode set to round-to-zero, and double rounding is OK except in round-to-nearest mode, so is OK for that intermediate round-to-zero computation.) mul and div will need slightly different special versions for i386 (using round-to-odd on long double instead of precision control) because of the possibility of inexact intermediate results in the subnormal range for double. To reduce duplication among the different function implementations, math-narrow.h gets macros CHECK_NARROW_ADD, NARROW_ADD_ROUND_TO_ODD and NARROW_ADD_TRIVIAL. In the trivial cases and for any architecture-specific optimized implementations, the overhead of the errno setting might be significant, but I think that's best handled through compiler built-in functions rather than providing separate no-errno versions in glibc (and likewise there are no __*_finite entry points for these function provided, __*_finite effectively being no-errno versions at present in most cases). Tested for x86_64 and x86, with both GCC 6 and GCC 7. Tested for mips64 (all three ABIs, both hard and soft float) and powerpc with GCC 7.

Add _Float32 function aliases.
This patch concludes filling out TS 18661-3 support for different types by adding *f32 function aliases of float functions to support _Float32.

As with the previous such patches there are some x86 ulps updates because of inline functions present for float but not for _Float32.

Add _Float64, _Float32x function aliases.
This patch continues filling out TS 18661-3 support by adding *f64 and *f32x function aliases, supporting _Float64 and _Float32x, as aliases for double functions. These types are supported for all glibc configurations. The API corresponds exactly to that for _Float128 and _Float64x. _Float32 aliases to float functions remain to be added in subsequent patches to complete this process (then there are a few miscellaneous functions in TS 18661-3 to implement that aren't simply versions of existing functions for new types). The patch enables the feature in bits/floatn-common.h, adds symbol versions and documentation with updates to ABI baselines, and arranges for the libm functions for the new types to be tested.

Linux: Implement interfaces for memory protection keys
This adds system call wrappers for pkey_alloc, pkey_free, pkey_mprotect, and x86-64 implementations of pkey_get and pkey_set, which abstract over the PKRU CPU register and hide the actual number of memory protection keys supported by the CPU. pkey_mprotect with a -1 key is implemented using mprotect, so it will work even if the kernel does not support the pkey_mprotect system call. The system call wrapers use unsigned int instead of unsigned long for parameters, so that no special treatment for x32 is needed. The flags argument is currently unused, and the access rights bit mask is limited to two bits by the current PKRU register layout anyway.

Linux: Add memfd_create system call wrapper
The system call is somewhat obscure because it is closely related to file descriptor sealing. However, it is also the recommended way to create alias mappings, which is why it has more general use. No emulation is provided. Except for the name of the /proc/self/fd links, it would be possible to implement an approximation using O_TMPFILE and tmpfs, but this does not appear to be worth the added complexity.

posix: Consolidate Linux glob implementation
This patch consolidates the glob implementation. The main changes are:
* On Linux all implementation now uses the default one at
sysdeps/unix/sysv/linux/glob{free}{64}.c with the exception
of alpha (which requires specific versioning) and s390-32 (which
different than other 32 bits ports it does not add a compat one
symbol for 2.1 version).
* The default implementation uses XSTAT_IS_XSTAT64 to define whether
both glob{free} and glob{free}64 should be different implementations.
For archictures that define XSTAT_IS_XSTAT64, glob{free} is an alias
to glob{free}64.
* Move i386 olddirent.h header to Linux default directory, since it is
the only header with this name and it is shared among different
architectures (and used on compat glob symbol as well).
Checked on x86_64-linux-gnu and on a build using build-many-glibcs.py
for all major architectures.

Remove cancellation support for syscall generation
This patch removes the cancellation mark from the auto-generation syscall script. Now all the cancellable syscalls are done throught C code using the SYSCALL_CANCEL macro. It simplifies the assembly required to each architecture port, since the SYSCALL_CANCEL uses the already defined INLINE_SYSCALL macros, and allows a more straigh fix on cancellation machanism (since no more specific assembly fixes will be required).

Call exit directly in clone (BZ #21512)
On aarch64, alpha, arm, hppa, mips, nios2, powerpc, sh, sparc, tile, and x86_64 the clone syscall jumps to _exit after the child execution and the function ends the process execution by calling exit_group. This behavior have a small issue where threads created with CLONE_THREAD using clone syscall directly will eventually exit the whole group altogether instead of just the thread created. Also, s390, microblaze, ia64, i386, and m68k differs by calling exit syscall directly. This patch changes all architectures to call the exit syscall directly, as for s390, microblaze, ia64, i386, and m68k. This do not have change glibc internal behavior in any sort, since the only usage of clone implementation in posix_spawn calls _exit directly in the created child (fork uses a direct call to clone). Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu, powerpc-linux-gnu, powerpc64le-linux-gnu, sparc64-linux-gnu, and sparcv9-linux-gnu.

posix: Implement preadv2 and pwritev2
This patch adds support of preadv2 and pwritev2 which are similar to
preadv/pwritev but with an extra flag argument. As for preadv/pwritev
both interfaces are added a non-standard GNU API.
For default 'posix' implementation trying to emulate the Linux supported
flags is troublesome:
* We can not temporary change the file state of the O_DSYNC and O_SYNC
flags to emulate RWF_{D}SYNC (attempts to change the state of using
fcntl are silently ignored).
* IOCB_HIPRI requires the file opened in O_DIRECT and uses an internal
semantic not provided by any other flag (O_NONBLOCK for instance).
So default sysdeps/posix implementations fails with EOPNOTSUPP for any non
supported flag (which are none currently) calls generic preadv/pwritev.
Basically this implementation supports only preadv2 called as preadv (with
flags sets to 0).
The Linux one uses the preadv2/pwritev2 syscall if defined, otherwise it
call preadv/writev. Instead of using the previous __ASSUME_* to
unconditionally issue the syscall (and avoid building the fallback routine),
it call pread/write if the preadv2/pwritev2 syscalls fails. The idea
is just avoid adding another __ASSUME_* and checking each architecture
on every kernel bump and simplify code conditionals.

Add reallocarray function

Build divdi3 only for architecture that required it
As noted in [1], divdi3 object is only exported in a handful ABIs
(i386, m68k, powerpc32, s390-32, and ia64), however it is built
for all current architectures regardless.
This patch refact the make rules for this object to so only the
aforementioned architectures that actually require it builds it.
Also, to avoid internal PLT calls to the exported symbol from the
module, glibc uses an internal header (symbol-hacks.h) which is
unrequired (and in fact breaks the build for architectures that
intend to get symbol definitions from libgcc.a). The patch also
changes it to create its own header (divdi3-symbol-hacks.h) and
adjust the architectures that require it accordingly.
I checked the build/check (with run-built-tests=no) on the
following architectures (which I think must cover all supported
ABI/builds) using GCC 6.3:

Make soft-float powerpc swapcontext restore the signal mask (bug 21045).
The soft-float powerpc version of swapcontext does not restore the signal mask, resulting in stdlib/tst-setcontext2 failing: after getcontext after setcontext after swapcontext FAIL: SIGUSR2 is blocked after swapcontext. This patch fixes this by adjusting the arguments passed to __sigprocmask so that it restores the saved signal mask as well as saving the existing one. (For hard-float, this code is only used for a compat symbol, not for the current version of swapcontext.) Tested for soft-float powerpc.

Add fromfp functions.
TS 18661-1 defines fromfp functions (fromfp, fromfpx, ufromfp, ufromfpx, and float and long double variants) to convert from floating-point to an integer type with any signedness and any given width up to that of intmax_t, in any of the five IEEE rounding modes (the usual four for binary floating point, plus rounding to nearest with ties rounding away from zero), with control of whether in-range non-integer values should result in the "inexact" exception being raised. This patch implements these functions for glibc. These implementations are (apart from raising exceptions) pure integer implementations; it's entirely possible optimized versions could be devised for some architectures. A common math/fromfp.h header provides various common helper code that can readily be shared between the implementations for different types. For each type, the bulk of the implementation is also shared between the four functions, with wrappers that define UNSIGNED and INEXACT macros appropriately before including the main implementation. As the functions return intmax_t and uintmax_t without math.h being allowed to expose those typedef names, they are declared using __intmax_t and __uintmax_t as obtained from <bits/types.h>. The FP_INT_* rounding direction macros are defined as ascending integers in the order the names are listed in the TS; I see no significant value in allowing architectures to vary the values of them. The libm-test machinery is duly adapted to handle unsigned int arguments, and intmax_t and uintmax_t results. Because each test input is generally tested for four functions, five rounding modes and several different widths, the libm-test.inc additions are very large. Thus, the diffs in the body of this message exclude the libm-test.inc changes, with the full patch being attached gzipped. The bulk of the new tests were generated (expanded from a test input plus rounding results and information about where it lies in the relevant interval between integers, to libm-test tests for all relevant combinations of function, rounding direction and width) by a script that's included in the patch as math/gen-fromfp-tests.py (input data math/gen-fromfp-tests-inputs); as an ad hoc script that's not really expected to be rerun, it's not very polished, but it's at least plausibly useful for adding any further tests for these functions in future. I may split the libm-test tests up by function in future (so both libm-test.inc and auto-libm-test-out are split into separate files, and the tests for each function are also built and run separately), but not for 2.25. For no obvious reason, adding tgmath tests for the new functions resulted in -Wuninitialized errors from test-tgmath.c about the variable i being used uninitialized. Those errors were correct - the variable is read by the frexp version in test-tgmath.c (where real frexp would write through that pointer instead of reading it) - but I don't know why this patch would result in the pre-existing issue being newly detected. The patch initializes the variable to avoid those errors. With these changes, glibc 2.25 should have all the library features from TS 18661-1 other than the functions that round result to narrower type (and constant rounding directions, but I'm considering those mainly a compiler feature not a library one).

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.

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. |

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.

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. Tested for x86_64, x86, mips64 and powerpc. * math/bits/mathcalls.h [__GLIBC_USE (IEC_60559_BFP_EXT)] (setpayloadsig): New declaration. * math/Versions (setpayloadsig): New libm symbol at version GLIBC_2.25.

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.

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.

Consolidate Linux truncate implementations
This patch consolidates all Linux truncate implementation on
sysdeps/unix/sysv/linux/truncate{64}.c. It is based on
{INTERNAL,INLINE}_SYSCALL patch [1] to simplify the syscall
construction.
General idea is to build ftruncate iff __OFF_T_MATCHES_OFF64_T is not
defined, otherwise ftruncate64 will be build and ftruncate will be an
alias. The fallocate will use old compat syscall and pass 32-bit off_t
argument, while fallocate64 will handle the correct off64_t passing using
__ALIGNMENT_ARG and SYSCALL_LL64 macros.
Tested on x86_64, i386, aarch64, and armhf.
* sysdeps/unix/sysv/linux/arm/truncate64.c: Remove file.
* sysdeps/unix/sysv/linux/generic/wordsize-32/truncate.c: Likewise.
* sysdeps/sysv/linux/generic/wordsize-32/truncate64.c: Likewise.
* sysdeps/unix/sysv/linux/mips/mips32/truncate64.c: Likewise.
* sysdeps/unix/sysv/linux/mips/mips64/truncate64.c: Likewise.
* sysdeps/unix/sysv/linux/powerpc/powerpc32/truncate64.c: Likewise.
* sysdeps/unix/sysv/linux/wordsize-64/truncate64.c: Likewise.
* sysdeps/unix/sysv/linux/truncate.c: New file.
* sysdeps/unix/sysv/linux/truncate64.c (truncate64): Use
INLINE_SYSCALL_CALL, __ALIGNMENT_ARG and SYSCALL_LL64 macros.
* sysdeps/unix/sysv/linux/mips/mips64/syscalls.list (truncate):
Remove.
* sysdeps/unix/sysv/linux/wordsize-64/syscalls.list (truncate):
Likewise.
