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). This patch removes all the unused frame.h headers and definitions of those macros.

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. 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 sub.

Refactor Linux ARCH_FORK implementation
This patch refactors the ARCH_FORK macro and the required architecture specific header to simplify the required architecture definitions to provide the fork syscall semantic and proper document current Linux clone ABI variant. Instead of require the reimplementation of arch-fork.h header, this patch changes the ARCH_FORK to an inline function with clone ABI defined by kernel-features.h define. The generic kernel ABI meant for newer ports is used as default and redefine if the architecture requires. Checked on x86_64-linux-gnu and i686-linux-gnu.

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. Tested with build-many-glibcs.py with both GCC 6 and GCC 7. * math/Makefile (libm-narrow-fns): Add add.

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 _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. Tested for x86_64 and x86, and with build-many-glibcs.py, with both GCC 6 and GCC 7. * bits/floatn-common.h (__HAVE_FLOAT32): Define to 1. * manual/math.texi (Mathematics): Document support for _Float32. * math/Makefile (test-types): Add float32. * math/Versions (GLIBC_2.27): Add _Float32 functions. * stdlib/Versions (GLIBC_2.27): Likewise. * wcsmbs/Versions (GLIBC_2.27): Likewise. * sysdeps/unix/sysv/linux/aarch64/libc.abilist: Update. * sysdeps/unix/sysv/linux/aarch64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/alpha/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/alpha/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/arm/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/arm/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/hppa/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/hppa/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/i386/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/i386/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/ia64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/ia64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/m680x0/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/m680x0/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/microblaze/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/microblaze/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/fpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/nofpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/nios2/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/nios2/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc-le.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm-le.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/sh/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/sh/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/libm.abilist: Likewise. * sysdeps/i386/fpu/libm-test-ulps: Likewise. * sysdeps/i386/i686/fpu/multiarch/libm-test-ulps: Likewise. |

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).

Add elision tunables
This patch adds several new tunables to control the behavior of elision on supported platforms[1]. Since elision now depends on tunables, we should always *compile* with elision enabled, and leave the code disabled, but available for runtime selection. This gives us *much* better compile-time testing of the existing code to avoid bit-rot[2]. Tested on ppc, ppc64, ppc64le, s390x and x86_64. [1] This part of the patch was initially proposed by Paul Murphy but was "staled" because the framework have changed since the patch was originally proposed: https://patchwork.sourceware.org/patch/10342/ [2] This part of the patch was inititally proposed as a RFC by Carlos O'Donnell.

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.

S390: Fix backtrace in vdso functions.
On s390, GDB fails to show the complete backtrace from within vdso functions. The macro INTERNAL_VSYSCALL_CALL saves the return address in r14 to r10 before branching to the vdso function. The branch-instruction updates r14 in order to let the vdso function return. Then the original address in r14 is restored from r10. Unfortunately, there are no cfi-rules and GDB fails. Furthermore the call of the vdso function does not comply with the s390 ABI as no stack-frame for the vdso-function is generated. This patch removes the s390 specific macro INTERNAL_VSYSCALL_CALL and the common implementation in sysdeps/unix/sysv/linux/sysdep-vdso.h is used. Then the vdso function is called via function-pointer and GCC generates a new stack-frame and emits all needed cfi-rules. The defines CLOBBER_[0-6] are removed as they were only used in macro INTERNAL_VSYSCALL_CALL. The macro INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK is not used on s390. The only user is power. Thus it is removed from s390 sysdep.h. ChangeLog: * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h (INTERNAL_VSYSCALL_CALL, CLOBBER_0, CLOBBER_1, CLOBBER_2, CLOBBER_3, CLOBBER_4, CLOBBER_5, CLOBBER_6, INTERNAL_VSYSCALL_NO_SYSCALL_FALLBACK): Remove. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h: Likewise. |

Add _Float64x function aliases.
This patch continues filling out TS 18661-3 support by adding *f64x function aliases on platforms with _Float64x support. (It so happens the set of such platforms is exactly the same as the set of platforms with _Float128 support, although on x86_64, x86 and ia32 the _Float64x format is Intel extended rather than binary128.) The API provided corresponds exactly to that provided for _Float128, mostly coming from TS 18661-3. As these functions always alias those for another type (long double, _Float128 or both), __* function names are not provided, as in other cases of alias types. Given the preparation done in previous patches, this one just enables the feature via Makeconfig and bits/floatn.h, adds symbol versions, and updates documentation and ABI baselines. The symbol versions are present unconditionally as GLIBC_2.27 in the relevant Versions files, as it's OK for those to specify versions for functions that may not be present in some configurations; no additional complexity is needed unless in future some configuration gains support for this type that didn't have such support in 2.27. The Makeconfig additions for ia64 and x86 aren't strictly needed, as those configurations also get float64x-alias-fcts definitions from sysdeps/ieee754/float128/Makeconfig, but still seem appropriate given that _Float64x is not _Float128 for those configurations. A libm-test-ulps update for x86 is included. This is because bits/mathinline.h does not have _Float64x support added and for two functions the use of out-of-line functions results in increased ulps (ifloat64x shares ulps with ildouble / ifloat128 as appropriate). Given that we'd like generally to eliminate bits/mathinline.h optimizations, preferring to have such optimizations in GCC instead, it seems reasonable not to add such support there for new types. GCC support for _FloatN / _FloatNx built-in functions is limited, but has been improved in GCC 8, and at some point I hope the full set of libm built-in functions in GCC, and other optimizations with per-floating-type aspects, will be enabled for all _FloatN / _FloatNx types.

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.

S390: Add cfi information for start routines in order to stop unwinding.
GDB failed to detect the outermost frame while showing the backtrace
within a thread:
Backtrace stopped: previous frame identical to this frame (corrupt stack?)
Before this patch, the start routines like thread_start had no cfi information.
GDB is then using the prologue unwinder if no cfi information is available.
This unwinder tries to unwind r15 and stops e.g. if r15 was updated or
on some jump-instructions.

Consolidate Linux sigpending() implementation
ia64, s390-64, sparc64 and x86_64 host their own implementation of sigpending() in corresponding files, but they are identical to generic linux file despite few comments.

Add _Float128 function aliases.
This patch adds support for *f128 function aliases on platforms where long double has the binary128 format (and thus GCC 7 provides the _Float128 type with the same ABI as long double but as a distinct type in terms of C type compatibility). This is the same API as provided in glibc 2.26 for powerpc64le / x86_64 / x86 / ia64 where _Float128 has a different format from long double, with the bulk of the API coming from TS 18661-3. All the functions alias the corresponding long double functions, and __* function names are not provided since those are only needed once for each floating-point format, not more than once for different types with the same format (so for example, -ffinite-math-only maps foof128 to __fool_finite, while type-generic macros end up calling e.g. __issignalingl for _Float128 arguments on such platforms). The preparation for this feature was done in previous patches, so this one just needs to add the relevant makefile and header definitions, and update macro definitions of libm_alias_ldouble_other_r, to turn on the feature, and update documentation and ABI baselines. Tested (a) for x86_64, (b) for aarch64, (c) with build-many-glibcs.py with both GCC 6 and GCC 7. * sysdeps/ieee754/ldbl-128/Makeconfig: New file. * sysdeps/ieee754/ldbl-128/bits/floatn.h: Likewise. * sysdeps/ieee754/ldbl-128/float128-abi.h: Likewise. * sysdeps/generic/libm-alias-ldouble.h: Include <bits/floatn.h>.

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.

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

Remove NO_CANCELLATION macro
The NO_CANCELLATION macro is used currently on generic headers to define non cancellable syscalls and on Linux fcntl to implement the non cancellable variation. Former should be single-handled by not-cancel.h header and former could be simplified build both cancellable and non cancellable for default objects and alias the non-cancellable to default one for rtld ones (since Linux already support cancellation as default). This patch thus removes the NO_CANCELLATION macro and its usage. The generic non cancellable fcntl is route to internal fcntl. Checked on x86_64-linux-gnu and i686-linux-gnu.

Fix mcontext_t sigcontext namespace (bug 21457).
This patch completes the ucontext.h namespace fixes by fixing issues related to the use of struct sigcontext as mcontext_t, and inclusion of <bits/sigcontext.h> even when struct sigcontext is not so used. Inclusion of <bits/sigcontext.h> by <sys/ucontext.h> is removed; the way to get the sigcontext structure is by including <signal.h> (in a context where __USE_MISC is defined); the sysdeps/generic version of sys/ucontext.h keeps the inclusion by necessity, with a comment about how this is not namespace-clean, but the only configuration that used it, MicroBlaze, gets its own version of the header in this patch. Where mcontext_t was typedefed to struct sigcontext, the contents of struct sigcontext are inserted (with appropriate namespace handling to prefix fields with __ when __USE_MISC is not defined); review should check that this has been done correctly in each case, whether the definition of struct sigcontext comes from glibc headers or from the Linux kernel. This changes C++ name mangling on affected architectures (which do not include x86_64/x86).

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). Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu.A Also with build-many-glibc.py with remaning touched architectures. * sysdeps/unix/make-syscalls.sh: Remove cancellable tagging for syscall definitions. * sysdeps/unix/syscall-template.S (SYSCALL_CANCELLABLE): Remove definition. * sysdeps/unix/sysv/linux/aarch64/sysdep-cancel.h (PSEUDO): Remove definition.

sys/ptrace.h: remove obsolete Linux PTRACE_SEIZE_DEVEL constant [BZ #21928]
Remove enum __ptrace_flags along with the only constant it contains, PTRACE_SEIZE_DEVEL, from Linux's sys/ptrace.h files. This temporary development constant shouldn't have been added to sys/ptrace.h in the first place. It was introduced in Linux by commit v3.1-rc1~308^2~28 as a temporary part of new experimental PTRACE_SEIZE interface. Later, as PTRACE_SEIZE stabilized and lost its experimental status, this flag was removed from Linux by commit v3.4-rc1~109^2~20. * sysdeps/unix/sysv/linux/sys/ptrace.h (enum __ptrace_flags, PTRACE_SEIZE_DEVEL): Remove. * sysdeps/unix/sysv/linux/aarch64/sys/ptrace.h: Likewise. * sysdeps/unix/sysv/linux/ia64/sys/ptrace.h: Likewise. * sysdeps/unix/sysv/linux/powerpc/sys/ptrace.h: Likewise. * sysdeps/unix/sysv/linux/s390/sys/ptrace.h: Likewise. * sysdeps/unix/sysv/linux/sparc/sys/ptrace.h: Likewise. |

Fix uc_* namespace (bug 21457).
The standard members of ucontext_t, in all standard versions with that type, are uc_link, uc_sigmask, uc_stack and uc_mcontext. The uc_* namespace is mostly reserved for additions to the structure. However, in XPG4.2, it's only reserved when <ucontext.h> is included, not when <signal.h> is included, while <signal.h> is required to define ucontext_t (but not allowed to make visible other symbols from <ucontext.h>). Thus, nonstandard members should avoid uc_* names. Some already do use __uc_*, but others don't; most architectures (all except ia64, I think) have a member uc_flags and some have additional members beyond that. This patch makes nonstandard members have an __ prefix unless __USE_MISC is defined. Members whose names indicate they are solely padding / reserved for future use are renamed unconditionally to use the __glibc_reserved1 naming convention. This is part of the preparation for a revised version of the mcontext_t / sigcontext patch to be able to eliminate all 13 of the miscellaneous XFAILs in conform/Makefile, rather than only 11 of them as at present (at least one further fix on top of this one will be needed for that as well). Tested for x86_64, and with build-many-glibcs.py. [BZ #21457] * sysdeps/arm/sys/ucontext.h (__ctx): Move undefine further down. (ucontext_t): Use __ctx with uc_flags.

Fix XPG4.2 bits/sigaction.h namespace (bug 21899).
For XPG4.2, sa_sigaction, SA_ONSTACK, SA_RESETHAND, SA_RESTART and SA_NODEFER should be defined in signal.h, but they are only defined for other standards at present. This patch fixes the various bits/sigaction.h headers accordingly. All the fixes are essentially the same, except those for SPARC and Tile. For SPARC, the header (a) spuriously defined various nonstandard macros for __USE_UNIX98 || defined __USE_XOPEN2K8 and (b) defined some standard macros as aliases of nonstandard ones instead of the other way round. This patch fixes the SPARC header to handle these macros the same way and with the same conditions as those for other architectures, so the standard macros are the primary ones and the other ones are defined only for __USE_MISC and are aliases of the standard ones where applicable. For Tile, the header spuriously defined the nonstandard macro SA_NOPTRACE for __USE_UNIX98 || defined __USE_XOPEN2K8; this is moved to __USE_MISC. (Those nonstandard macros are in a reserved namespace, but it seems desirable to be consistent between architectures as far as possible, and so not define them in standard modes anywhere.) Tested for x86_64, and with build-many-glibcs.py. [BZ #21899] * bits/sigaction.h (struct sigaction): Define sa_handler and sa_sigaction using union also for [__USE_XOPEN_EXTENDED].

S390: Fix tst-ptrace-singleblock if kernel does not support PTRACE_SINGLEBLOCK.
The request PTRACE_SINGLEBLOCK was introduced in Linux 3.15. Thus the ptrace call will fail on older kernels. Thus the test is now testing PTRACE_SINGLEBLOCK with data argument pointing to a buffer on stack which is assumed to fail. If the request would be interpreted as PTRACE_GETREGS, then the ptrace call will not fail and the regs are written to buf. If we run with a kernel with support for PTRACE_SINGLEBLOCK a ptrace call with data=NULL, returns zero with no error. If we run with a kernel without support for PTRACE_SINGLEBLOCK a ptrace call with data=NULL reports an error. In the latter case, the test is just continuing with PTRACE_CONT. ChangeLog: * sysdeps/unix/sysv/linux/s390/tst-ptrace-singleblock.c: Support running on kernels without PTRACE_SINGLEBLOCK. |

Rename struct ucontext tag (bug 21457).
The ucontext_t type has a tag struct ucontext. As with previous such issues for siginfo_t and stack_t, this tag is not permitted by POSIX (is not in a reserved namespace), and so namespace conformance means breaking C++ name mangling for this type. In this case, the type does need to have some tag rather than just a typedef name, because it includes a pointer to itself. This patch uses struct ucontext_t as the new tag, so the type is mangled as ucontext_t (the POSIX *_t reservation applies in all namespaces, not just the namespace of ordinary identifiers). Another reserved name such as struct __ucontext could of course be used. Because of other namespace issues, this patch does not by itself fix bug 21457 or allow any XFAILs to be removed. Tested for x86_64, and with build-many-glibcs.py.

S390: Sync ptrace.h with kernel. [BZ #21539]
This patch removes PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS as these requests does not exist on s390 kernel. But the kernel has support for PTRACE_SINGLEBLOCK, PTRACE_SECCOMP_GET_FILTER, PTRACE_PEEKUSR_AREA, PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE, PTRACE_DISABLE_TE and PTRACE_TE_ABORT_RAND. Thus those are defined now. The current kernel s390 specific ptrace.h file also defines PTRACE_PEEKTEXT_AREA, PTRACE_PEEKDATA_AREA, PTRACE_POKETEXT_AREA, PTRACE_POKEDATA_AREA, PTRACE_PEEK_SYSTEM_CALL, PTRACE_POKE_SYSTEM_CALL and PTRACE_PROT, but those requests are not supported. Thus those defines are skipped in glibc ptrace.h. There were old includes of ptrace.h in sysdeps/s390/fpu/fesetenv.c. The ptrace feature isn't used there anymore, thus I removed the includes. Before this patch, <glibc>/sysdeps/unix/sysv/linux/s390/sys/ptrace.h uses ptrace-request 12 for PTRACE_GETREGS, but <kernel>/include/uapi/linux/ptrace.h uses 12 for PTRACE_SINGLEBLOCK. The s390 kernel has never had support for PTRACE_GETREGS! Thus glibc ptrace.h is adjusted to match kernel ptrace.h. The new s390 specific test ensures, that PTRACE_SINGLEBLOCK defined in glibc works as expected. If the kernel would interpret it as PTRACE_GETREGS, then the testcase will not make any progress and will time out. ChangeLog: [BZ #21539] * NEWS: Mention s390 ptrace request changes. * sysdeps/unix/sysv/linux/s390/sys/ptrace.h (PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS, PTRACE_SETFPREGS): Remove enum constant. (PT_GETREGS, PT_SETREGS, PT_GETFPREGS, T_SETFPREGS): Remove defines. (PTRACE_SINGLEBLOCK): New enum constant. (PT_STEPBLOCK): New define. (PTRACE_PEEKUSR_AREA, PTRACE_POKEUSR_AREA, PTRACE_GET_LAST_BREAK, PTRACE_ENABLE_TE, PTRACE_DISABLE_TE, PTRACE_TE_ABORT_RAND): New enum constant and define. * sysdeps/s390/fpu/fesetenv.c: Remove ptrace.h includes. * sysdeps/unix/sysv/linux/s390/tst-ptrace-singleblock.c: New file. * sysdeps/unix/sysv/linux/s390/Makefile: Add test. |

S390: Fix build with gcc configured with --enable-default-pie. [BZ #21537]
Building glibc with gcc configured with --enable-default-pie failed on s390 due to assembler messages: ../sysdeps/unix/sysv/linux/s390/s390-32/__makecontext_ret.S:44: Error: junk at end of line, first unrecognized character is `@' HIDDEN_JUMPTARGET was expanded to exit@PLT@GOTOFF. If SHARED is not defined, HIDDEN_JUMPTARGET is defined to JUMPTARGET in sysdeps/s390/s390-32/sysdep.h. There it expanded to exit@PLT in non SHARED case as PIC is defined if gcc is configured with --enable-default-pie. Thus I've changed the "ifdef PIC" to "ifdef SHARED" as we do not want PLTs in the static obj files. I've also changed this in sysdeps/s390/s390-64/sysdep.h. I've also adjusted sysdeps/unix/sysv/linux/s390/s390-32/__makecontext_ret.S. If glibc is configured with --disable-hidden-plt, then NO_HIDDEN is defined. In SHARED case HIDDEN_JUMPTARGET would be expanded to exit@PLT@GOTOFF instead of __GI_exit@GOTOFF. Now we jump to: - __GI_exit if SHARED is defined - exit@PLT if SHARED and NO_HIDDEN is defined - exit if both are not defined. On s390 31bit we have to setup GOT pointer in r12 if we use a PLT stub. Therefore I use SYSCALL_PIC_SETUP from sysdep.h and added the missing semicolons. ChangeLog: [BZ #21537] * sysdeps/s390/s390-32/sysdep.h (JUMPTARGET, SYSCALL_PIC_SETUP): Check SHARED instead of PIC. (SYSCALL_PIC_SETUP): Add missing semicolons. * sysdeps/s390/s390-64/sysdep.h (JUMPTARGET, SYSCALL_PIC_SETUP): Check SHARED instead of PIC. * sysdeps/unix/sysv/linux/s390/s390-32/__makecontext_ret.S (__makecontext_ret): Adjust code to jump to exit. |

s390: optimize syscall function
Since kernel 2.6.0 all Linux version accept the system call number
in register 1 for svc 0. There is no need to have special handling
that uses EX for system calls < 256. This will simplify and speed
up that code.
A microbenchmark doing "syscall(__NR_getpid);" in a loops gets faster
by ~12%.
* sysdeps/unix/sysv/linux/s390/s390-32/syscall.S: Simplify
code by always using SVC 0 instead of EX.
* sysdeps/unix/sysv/linux/s390/s390-64/syscall.S: Likewise.

Add include guards to dl-procinfo.h
The dl-procinfo.h for linux/s390 and linux/i386 don't have include guards, which causes them to fail since addition of LD_HWCAP_MASK to tunables. Add _DL_I386_PROCINFO_H guard to avoid redefining _dl_procinfo on multiple includes and also allow the subsequent include of another dl-procinfo.h to work. Verified with a build test on i686. * sysdeps/unix/sysv/linux/i386/dl-procinfo.h: Add include guard. * sysdeps/unix/sysv/linux/s390/dl-procinfo.h: Likewise. |
