nptl: Move pthread_gettattr_np into libc
This is part of the libpthread removal project:
<https://sourceware.org/ml/libc-alpha/2019-10/msg00080.html>
Use __getline instead of __getdelim to avoid a localplt failure.
Likewise for __getrlimit/getrlimit.
The abilist updates were performed by:
git ls-files 'sysdeps/unix/sysv/linux/**/libc.abilist' \
| while read x ; do
echo "GLIBC_2.32 pthread_getattr_np F" >> $x
done
python3 scripts/move-symbol-to-libc.py --only-linux pthread_getattr_np
The private export of __pthread_getaffinity_np is no longer needed, but
the hidden alias still necessary so that the symbol can be exported with
versioned_symbol.

ld.so: Do not export free/calloc/malloc/realloc functions [BZ #25486]
Exporting functions and relying on symbol interposition from libc.so
makes the choice of implementation dependent on DT_NEEDED order, which
is not what some compiler drivers expect.
This commit replaces one magic mechanism (symbol interposition) with
another one (preprocessor-/compiler-based redirection). This makes
the hand-over from the minimal malloc to the full malloc more
explicit.
Removing the ABI symbols is backwards-compatible because libc.so is
always in scope, and the dynamic loader will find the malloc-related
symbols there since commit

Linux: Add tables with system call numbers
The new tables are currently only used for consistency checks with the installed kernel headers and the architecture-independent system call names table. They are based on Linux 5.4. The goal is to use these architecture-specific tables to ensure that system call wrappers are available irrespective of the version of the installed kernel headers. The tables are formatted in the form of C header files so that they can be used directly in an #include directive, without external preprocessing. (External preprocessing of a plain table file would introduce cross-subdirectory dependency issues.) However, the intent is that they can still be treated as tables and can be processed by simple tools. The irregular system call names on 32-bit arm add a complication. The <fixup-asm-unistd.h> header is introduced to work around that, and the system calls are listed under regular names in the <arch-syscall.h> file. A make target, update-syscalls-list, is added to patch the glibc sources with data from the current kernel headers. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org> |

Update sysvipc kernel-features.h files for Linux 5.1
Linux 5.1 adds missing SySV IPC syscalls to the syscall table for
remanining one that still uses the ipc syscall on glibc (m68k, mips-o32,
powerpc, s390, sh, and sparc32). However the newly added direct ipc
syscall are different than the old ones:
1. They do not expect IPC_64, meaning __IPC_64 should be set to zero
when new syscalls are used. And new syscalls can not be used
for compat functions like __old_semctl (to emulated old sysvipc it
requires to use the old __NR_ipc syscall without __IPC_64).
Thus IPC_64 is redefined for newer kernels on affected ABIs.
2. semtimedop and semop does not exist on 32-bit ABIs (only
semtimedop_time64 is supplied). The provided syscall wrappers only
uses the wire-up syscall if __NR_semtimedop and __NR_semop are
also defined.
Checked on x86_64-linux-gnu and i686-linux-gnu on both a 4.15 kernel
configure with default options and sysvipc tests on a 5.3.0 kernel with
--enable-kernel=5.1.

ipc: Refactor sysvipc internal definitions
This patch refactor the internal sysvipc in two main points:
1. Add a new __ASSUME_SYSVIPC_DEFAULT_IPC_64 to infer the __IPC_64
value to be used along either the multiplexed __NR_ipc or wired-up
syscall. The defaut value assumed for __IPC_64 is also changed
from 0x100 to 0x0, aligning with Linux generic UAPI. The idea
is to simplify the Linux 5.1 wire-up for sysvipc syscalls for
some 32-bit ABIs (which expectes __IPC_64 being 0x0) and simplify
new ports (which will no longer need to add ipc_priv.h).
2. It also removes some duplicated internal definition used on compat
sysvipc symbols defined at ipc_priv.h (more specifically the
__old_ipc_perm, SEMCTL_ARG_ADDRESS, MSGRCV_ARGS, and
SEMTIMEDOP_IPC_ARGS). The idea is also to make it simpler to enable
the new wire-up sysvipc syscall provided by Linux v5.1.
There is no semantic change expected on any port. Checked with a build
against all affected ABIs.

sysvipc: Set ipc_perm mode as mode_t (BZ#18231)
This patch sets the mode field in ipc_perm as mode_t for all architectures,
as POSIX specification [1]. The changes required are as follow:
1. It moves the ipc_perm definition out of ipc.h to its own header
ipc_perm.h. It also allows consolidate the IPC_* definition on
only one header.
2. The generic implementation follow the kernel ipc64_perm size so the
syscall can be made directly without temporary buffer copy. However,
since glibc defines the MODE field as mode_t, it omits the __PAD1 field
(since glibc does not export mode_t as 16-bit for any architecture).
It is a two-fold improvement:
2.1. New implementation which follow Linux UAPI will not need to
provide an arch-specific ipc-perm.h header neither wrongly
use the wrong 16-bit definition from previous default ipc.h
(as csky did).
2.1. It allows consolidate ipc_perm definition for architectures that
already provide mode_t as 32-bit.
3. All kernel ABIs for the supported architectures already provides the
expected padding for mode type extension to 32-bit. However, some
architectures the padding has the wrong placement, so it requires
the ipc control routines (msgctl, semctl, and shmctl) to adjust the
mode field accordingly. Currently they are armeb, microblaze, m68k,
s390, and sheb.
A new assume is added, __ASSUME_SYSVIPC_BROKEN_MODE_T, which the
required ABIs define.
4. For the ABIs that define __ASSUME_SYSVIPC_BROKEN_MODE_T, it also
require compat symbols that do not adjust the mode field.
Checked on arm-linux-gnueabihf, aarch64-linux-gnu, powerpc64le-linux-gnu,
and x86_64-linux-gnu. I also checked the sysvipc tests on hppa-linux-gnu,
sh4-linux-gnu, s390x-linux-gnu, and s390-linux-gnu.
I also did a sanity test against armeb qemu usermode for the sysvipc
tests.

Finish move of clock_* functions to libc. [BZ #24959]
In glibc 2.17, the functions clock_getcpuclockid, clock_getres, clock_gettime, clock_nanosleep, and clock_settime were moved from librt.so to libc.so, leaving compatibility stubs behind. Now that the dynamic linker no longer insists on finding versioned symbols in the same library that originally defined them, we do not need the stubs anymore, and this means we don't need GLIBC_PRIVATE __-prefix aliases for most of the functions anymore either. (clock_gettime still needs one.) For ports added before 2.17, libc.so needs to provide two symbol versions for each, the default at GLIBC_2.17 plus a compat version matching what librt had. While I'm at it, move the clock_*.c files and their tests from rt/ to time/. |

Refactor sigcontextinfo.h
This patch refactor sigcontextinfo.h header to use SA_SIGINFO as default
for both gmon and debug implementations. This allows simplify
profil-counter.h on Linux to use a single implementation and remove the
requirements for newer ports to redefine __sigaction/sigaction to use
SA_SIGINFO.
The GET_PC macro is also replaced with a function sigcontext_get_pc that
returns an uintptr_t instead of a void pointer. It allows easier convertion
to integer on ILP32 architecture, such as x32, without the need to suppress
compiler warnings.
The patch also requires some refactor of register-dump.h file for some
architectures (to reflect it is now called from a sa_sigaction instead of
sa_handler signal context).
- Alpha, i386, and s390 are straighfoward to take in consideration the
new argument type.
- ia64 takes in consideration the kernel pass a struct sigcontextt
as third argument for sa_sigaction.
- sparc take in consideration the kernel pass a pt_regs struct
as third argument for sa_sigaction.
- m68k dummy function is removed and the FP state is dumped on
register_dump itself.
- For SH the register-dump.h file is consolidate on a common implementation
and the floating-point state is checked based on ownedfp field.
The register_dump does not change its output format in any affected
architecture.
I checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu,

Make totalorder and totalordermag functions take pointer arguments.
The resolution of C floating-point Clarification Request 25 <http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2397.htm#dr_25> is that the totalorder and totalordermag functions should take pointer arguments, and this has been adopted in C2X (with const added; note that the integration of this change into C2X is present in the C standard git repository but postdates the most recent public PDF draft). This patch updates glibc accordingly. As a defect resolution, the API is changed unconditionally rather than supporting any sort of TS 18661-1 mode for compilation with the old version of the API. There are compat symbols for existing binaries that pass floating-point arguments directly. As a consequence of changing to pointer arguments, there are no longer type-generic macros in tgmath.h for these functions. Because of the fairly complicated logic for creating libm function aliases and determining the set of aliases to create in a given glibc configuration, rather than duplicating all that in individual source files to create the versioned and compat symbols, the source files for the various versions of totalorder functions are set up to redefine weak_alias before using libm_alias_* macros to create the symbols required. In turn, this requires creating a separate alias for each symbol version pointing to the same implementation (see binutils bug <https://sourceware.org/bugzilla/show_bug.cgi?id=23840>), which is done automatically using __COUNTER__. (As I noted in <https://sourceware.org/ml/libc-alpha/2018-10/msg00631.html>, it might well make sense for glibc's symbol versioning macros to do that alias creation with __COUNTER__ themselves, which would somewhat simplify the logic in the totalorder source files.) It is of course desirable to test the compat symbols. I did this with the generic libm-test machinery, but didn't wish to duplicate the actual tables of test inputs and outputs, and thought it risky to attempt to have a single object file refer to both default and compat versions of the same function in order to test them together. Thus, I created libm-test-compat_totalorder.inc and libm-test-compat_totalordermag.inc which include the generated .c files (with the processed version of those tables of inputs) from the non-compat tests, and added appropriate dependencies. I think this provides sufficient test coverage for the compat symbols without also needing to make the special ldbl-96 and ldbl-128ibm tests (of peculiarities relating to the representations of those formats that can't be covered in the generic tests) run for the compat symbols. Tests of compat symbols need to be internal tests, meaning _ISOMAC is not defined. Making some libm-test tests into internal tests showed up two other issues. GCC diagnoses duplicate macro definitions of __STDC_* macros, including __STDC_WANT_IEC_60559_TYPES_EXT__; I added an appropriate conditional and filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91451> for this issue. On ia64, include/setjmp.h ends up getting included indirectly from libm-symbols.h, resulting in conflicting definitions of the STR macro (also defined in libm-test-driver.c); I renamed the macros in include/setjmp.h. (It's arguable that we should have common internal headers used everywhere for stringizing and concatenation macros.)

nptl: Add POSIX-proposed pthread_cond_clockwait
Add:
int pthread_cond_clockwait (pthread_cond_t *cond,
pthread_mutex_t *mutex,
clockid_t clockid,
const struct timespec *abstime)
which behaves just like pthread_cond_timedwait except it always measures
abstime against the supplied clockid. Currently supports CLOCK_REALTIME
and
CLOCK_MONOTONIC and returns EINVAL if any other clock is specified.
Includes feedback from many others. This function was originally
proposed[1] as pthread_cond_timedwaitonclock_np, but The Austin Group
preferred the new name.

Remove obsolete, never-implemented XSI STREAMS declarations
The stub implementations are turned into compat symbols. Linux actually has two reserved system call numbers (for getpmsg and putpmsg), but these system calls have never been implemented, and there are no plans to implement them, so this patch replaces the wrappers with the generic stubs. According to <https://bugzilla.redhat.com/show_bug.cgi?id=436349>, the presence of the XSI STREAMS declarations is a minor portability hazard because they are not actually implemented. This commit does not change the TIRPC support code in sunrpc/rpc_svcout.c. It uses additional XTI functionality and therefore never worked with glibc.

Remove the error handling wrapper from pow
Introduce new pow symbol version that doesn't do SVID compatible error handling. The standard errno and fp exception based error handling is inline in the new code and does not have significant overhead. The wrapper is disabled for sysdeps/ieee754/dbl-64 by using empty w_pow.c and enabled for targets with their own pow implementation or ifunc dispatch on __ieee754_pow by including math/w_pow.c. The compatibility symbol version still uses the wrapper with SVID error handling around the new code. There is no new symbol version nor compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv). On targets where previously powl was an alias of pow, now it points to the compatibility symbol with the wrapper, because it still need the SVID compatible error handling. This affects NO_LONG_DOUBLE (e.g. arm) and LONG_DOUBLE_COMPAT (e.g. alpha) targets as well. The __pow_finite symbol is now an alias of pow. Both __pow_finite and pow set errno and thus not const functions. The ia64 asm is changed so the compat and new symbol versions map to the same address. On x86_64 #include <math.h> was added before macro definitions that may affect that header.

Remove the error handling wrapper from log

Remove the error handling wrapper from exp and exp2
Introduce new exp and exp2 symbol version that don't do SVID compatible error handling. The standard errno and fp exception based error handling is inline in the new code and does not have significant overhead. The double precision wrappers are disabled for sysdeps/ieee754/dbl-64 by using empty w_exp.c and w_exp2.c files, the math/w_exp.c and math/w_exp2.c files use the wrapper template and can be included by targets that have their own exp and exp2 implementations or use ifunc on the glibc internal __ieee754_exp symbol. The compatibility symbol versions still use the wrapper with SVID error handling around the new code. There is no new symbol version nor compatibility code on !LIBM_SVID_COMPAT targets (e.g. riscv). On targets where previously expl and exp2l were aliases of exp and exp2, now they point to the compatibility symbols with the wrapper, because they still need the SVID compatible error handling. This affects NO_LONG_DOUBLE (e.g arm) and LONG_DOUBLE_COMPAT (e.g. alpha) targets as well. The _finite symbols are now aliases of the standard symbols (they have no performance advantage anymore). Both the standard symbols and _finite symbols set errno and thus not const functions. The ia64 asm is changed so the compat and new symbol versions map to the same address. On x86_64 #include <math.h> was added before macro definitions that may affect that header (the new macro name is __exp instead of __ieee754_exp which breaks some math.h macros).

Remove __ASSUME_SOCKETCALL.
The __ASSUME_SOCKETCALL macro in kernel-features.h is no longer used for anything. (It used to be used in defining other macros related to accept4 / recvmmsg / sendmmsg availability, but the code in that area was simplified once we could assume a kernel with those features, whether through a syscall or through socketcall, so allowing those functions to be handled much like other socket operations, without requring __ASSUME_SOCKETCALL.) This patch removes that unused macro. (Note: once we can assume a Linux 4.4 or later kernel, much of the support for using socketcall at all can be removed from glibc, although a few functions may need that support in glibc for longer.) Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/kernel-features.h: Remove comment about __ASSUME_SOCKETCALL. * sysdeps/unix/sysv/linux/i386/kernel-features.h (__ASSUME_SOCKETCALL): Remove. * sysdeps/unix/sysv/linux/m68k/kernel-features.h (__ASSUME_SOCKETCALL): Likewise. * sysdeps/unix/sysv/linux/microblaze/kernel-features.h (__ASSUME_SOCKETCALL): Likewise. * sysdeps/unix/sysv/linux/powerpc/kernel-features.h (__ASSUME_SOCKETCALL): Likewise. * sysdeps/unix/sysv/linux/s390/kernel-features.h (__ASSUME_SOCKETCALL): Likewise. * sysdeps/unix/sysv/linux/sh/kernel-features.h (__ASSUME_SOCKETCALL): Likewise. * sysdeps/unix/sysv/linux/sparc/kernel-features.h (__ASSUME_SOCKETCALL): Likewise. |

Unify more sys/procfs.h headers.
This patch continues the process of unifying sys/procfs.h headers for architectures using the Linux kernel. A bits/procfs-id.h header is added to define __pr_uid_t and __pr_gid_t for the types of pr_uid and pr_gid; the default version of this header uses unsigned int. On some architectures, sys/procfs.h has copies of 32-bit structures for 64-bit builds; those move into a bits/procfs-extra.h header (they can't go in bits/procfs.h because they have to come *after* other declarations from sys/procfs.h). Given appropriate versions of these headers, six more architectures can then move to providing only bits/procfs*.h without duplicating the rest of the contents of sys/procfs.h. Only alpha needs a further bits/ header to be added before it can stop having its own sys/procfs.h. Tested for x86_64 and x86, and with build-many-glibcs.py. * sysdeps/unix/sysv/linux/sys/procfs.h: Include <bits/procfs-id.h> and <bits/procfs-extra.h>. (struct elf_prpsinfo): Use __pr_uid_t and __pr_gid_t as types of pr_uid and pr_gid. * sysdeps/unix/sysv/linux/Makefile [$(subdir) = misc] (sysdep_headers): Add bits/procfs-id.h and bits/procfs-extra.h. * sysdeps/unix/sysv/linux/bits/procfs-extra.h: New file. * sysdeps/unix/sysv/linux/bits/procfs-id.h: Likewise. * sysdeps/unix/sysv/linux/arm/bits/procfs-id.h: Likewise. * sysdeps/unix/sysv/linux/arm/bits/procfs.h: Likewise. * sysdeps/unix/sysv/linux/m68k/bits/procfs-id.h: Likewise. * sysdeps/unix/sysv/linux/m68k/bits/procfs.h: Likewise. * sysdeps/unix/sysv/linux/s390/bits/procfs-extra.h: Likewise. * sysdeps/unix/sysv/linux/s390/bits/procfs-id.h: Likewise. * sysdeps/unix/sysv/linux/s390/bits/procfs.h: Likewise. * sysdeps/unix/sysv/linux/sh/bits/procfs-id.h: Likewise. * sysdeps/unix/sysv/linux/sh/bits/procfs.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/procfs-extra.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/procfs-id.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/procfs.h: Likewise. * sysdeps/unix/sysv/linux/x86/bits/procfs-id.h: Likewise. * sysdeps/unix/sysv/linux/x86/bits/procfs.h: Likewise. * sysdeps/unix/sysv/linux/arm/sys/procfs.h: Remove file. * sysdeps/unix/sysv/linux/m68k/sys/procfs.h: Likewise. * sysdeps/unix/sysv/linux/s390/sys/procfs.h: Likewise. * sysdeps/unix/sysv/linux/sh/sys/procfs.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sys/procfs.h: Likewise. * sysdeps/unix/sysv/linux/x86/sys/procfs.h: Likewise. |

Unify many bits/mman.h headers.
Many bits/mman.h headers for Linux architectures have exactly the same contents, up to whitespace, comments and the number of leading 0s on constants. Specifically, this applies to architectures that, in the Linux kernel, either have no uapi/asm/mman.h, or have one that includes asm-generic/mman.h without any changes or additions relevant to glibc (this last case is the one that applies to Arm). It's not useful to have to duplicate the set of MAP_* constants in glibc for all such architectures and any new architectures with that property. Thus, this patch creates a generic sysdeps/unix/sysv/linux/bits/mman.h and removes all the architecture-specific versions that become unnecessary. Further unification remains possible after this patch. For example, the new bits/mman.h could become bits/mman-map-flags-generic.h so that it could also be used by architecture-specific bits/mman.h headers on architectures that use the generic flags but add architecture-specific ones to them. That would allow this common set of MAP_* definitions to be used on ia64 and x86 as well (architectures that include asm-generic/mman.h from their own uapi/asm/mman.h but define additional MAP_* values of their own). Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/bits/mman.h: New file. * sysdeps/unix/sysv/linux/aarch64/bits/mman.h: Remove. * sysdeps/unix/sysv/linux/arm/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/m68k/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/microblaze/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/nios2/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/riscv/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/s390/bits/mman.h: Likewise. * sysdeps/unix/sysv/linux/sh/bits/mman.h: Likewise. |

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.

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.

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 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,
sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu, and
powerpc64le-linux-gnu.

defined.

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

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

aarch64-linux-gnu, sparc64-linux-gnu, sparcv9-linux-gnu, powerpc-linux-gnu,

Remove unused frame.h header, sigcontextinfo.h macros.
The glibc-internal header frame.h was used in the old debug/backtrace.c but is now unused. Similarly, there are some sigcontextinfo.h macros that are used nowhere in glibc - ADVANCE_STACK_FRAME and FIRST_FRAME_POINTER were used in the old debug/backtrace.c, while SIGCONTEXT_EXTRA_ARGS, GET_FRAME, GET_STACK and CALL_SIGHANDLER were unused even before the removal of that old implementation (beyond uses of SIGCONTEXT_EXTRA_ARGS in definitions of CALL_SIGHANDLER).

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 MAP_SYNC from Linux 4.15.
This patch adds the MAP_SYNC macro from Linux 4.15 to various bits/mman.h headers. Note that this is *not* added to all architectures: in Linux 4.15, this macro is only in asm-generic/mman.h, and only some architectures' asm/mman.h include the asm-generic file - the architectures not using the asm-generic file will need their own values of MAP_SYNC allocated to support this functionality (some of them also already have conflicting mmap flags so the value there will have to be different from the generic 0x80000). Specifically, for glibc architectures, alpha hppa mips powerpc sparc tile lack allocations of values for MAP_SYNC. Tested for x86_64. * sysdeps/unix/sysv/linux/aarch64/bits/mman.h [__USE_MISC] (MAP_SYNC): New macro. * sysdeps/unix/sysv/linux/arm/bits/mman.h [__USE_MISC] (MAP_SYNC): Likewise. * sysdeps/unix/sysv/linux/ia64/bits/mman.h [__USE_MISC] (MAP_SYNC): Likewise. * sysdeps/unix/sysv/linux/m68k/bits/mman.h [__USE_MISC] (MAP_SYNC): Likewise. * sysdeps/unix/sysv/linux/microblaze/bits/mman.h [__USE_MISC] (MAP_SYNC): Likewise. * sysdeps/unix/sysv/linux/nios2/bits/mman.h [__USE_MISC] (MAP_SYNC): Likewise. * sysdeps/unix/sysv/linux/riscv/bits/mman.h [__USE_MISC] (MAP_SYNC): Likewise. * sysdeps/unix/sysv/linux/s390/bits/mman.h [__USE_MISC] (MAP_SYNC): Likewise. * sysdeps/unix/sysv/linux/sh/bits/mman.h [__USE_MISC] (MAP_SYNC): Likewise. * sysdeps/unix/sysv/linux/x86/bits/mman.h [__USE_MISC] (MAP_SYNC): Likewise. |

Add jmp_buf-macros.h for ColdFire.
This patch adds a jmp_buf-macros.h for ColdFire. In conjunction with a GCC patch to fix the libgcc build failure for ColdFire <https://gcc.gnu.org/ml/gcc-patches/2018-01/msg02064.html> this suffices to restore the build (tested with build-many-glibcs.py). A further patch will be needed for soft-float ColdFire (while the function-calling ABI is the same for hard-float and soft-float ColdFire, it turns out the glibc ABI is not - so another ColdFire variant will be needed in build-many-glibcs.py), but I'll deal with that separately. Tested with build-many-glibcs.py (m68k-linux-gnu and m68k-linux-gnu-coldfire).

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 _Float64 and _Float32x, this is supported for all glibc configurations. As with the previous such patches there are some x86 ulps updates because of inline functions present for float but not for _Float32. The patch also has the usual bits/floatn-common.h update, symbol versions, ABI baselines updates, test enablement and documentation.

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. As with the _Float64x changes there are some x86 ulps updates because of header inlines not used for the new types (and one other change to the non-multiarch libm-test-ulps, which I suppose comes from using a different compiler version / configuration from when it was last regenerated).

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.

Linux: Consolidate {RTLD_}SINGLE_THREAD_P definition
Current GLIBC has two ways to implement the single thread optimization
on syscalls to avoid calling the cancellation path: either by using
global variables (__{libc,pthread}_multiple_thread) or by accessing
the TCB field (defined by TLS_MULTIPLE_THREADS_IN_TCB). Both the
variables and the macros to acces its value are defined in the
architecture sysdep-cancel.h header.
This patch consolidates its definition on only one header,
sysdeps/unix/sysv/linux/sysdep-cancel.h, and adds a new define
(SINGLE_THREAD_BY_GLOBAL) which the architecture defines if it prefer
to use the global variables instead of the TCB field. This is an
optimization, so if the architecture does not define it, the TCB
method will be used as default.

New symbol version for logf, log2f and powf without SVID compat
This patch changes the logf, log2f and powf error handling semantics to only set errno accoring to POSIX rules. New symbol version is introduced at GLIBC_2.27. The old wrappers are kept for compat symbols. ia64 needed assembly change to have the new and compat versioned symbol map to the same function. All linux libm abilists are updated. * math/Versions (logf): New libm symbol at GLIBC_2.27. (log2f): Likewise.
