ld.so: Introduce struct dl_exception
This commit separates allocating and raising exceptions. This simplifies catching and re-raising them because it is no longer necessary to make a temporary, on-stack copy of the exception message. |

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.

aarch64: Optimized memcpy for Qualcomm Falkor processor
This is an optimized implementation of the memcpy routine that gives a significant gain in performance for all sizes of copies on the Qualcomm Falkor processor. A detailed rationale of the implementation is written in a comment in the patch. This implementation improves time for copies up to 128 bytes by up to 15% and for larger copies by up to 35% in the glibc microbenchmark. The memcpy-random benchmark sees improvements in all sizes in the range of 13%-18%. Here are the full numbers extracted from the glibc microbenchmark using the commands: ../benchtests/scripts/compare_strings.py benchtests/bench-memcpy.out \

Do not use __ptr_t.
sys/cdefs.h has a macro __ptr_t, which a few places in glibc use instead of void *. void * is a well-understood standard type for that purpose and in a post-C89 context there is no need for a macro for it; this patch changes those places to use void * directly instead. Unlike __long_double_t, __ptr_t is widely used outside glibc (or at least has many hits on codesearch.debian.net). I don't know how many of those uses would break if sys/cdefs.h ceased to define the macro, but there's enough risk that this patch leaves the definition and just removes the uses within glibc; removal of the definition can be considered separately if desired.

i386: Add <startup.h> [BZ #21913]
On Linux/i386, there are 3 ways to make a system call: 1. call *%gs:SYSINFO_OFFSET. This requires TLS initialization. 2. call *_dl_sysinfo. This requires relocation of _dl_sysinfo. 3. int $0x80. This is slower than #2 and #3, but works everywhere. When an object file is compiled with PIC, #1 is prefered since it is faster than #3 and doesn't require relocation of _dl_sysinfo. For dynamic executables, ld.so initializes TLS. However, for static executables, before TLS is initialized by __libc_setup_tls, #3 should be used for system calls. This patch adds <startup.h> which defines _startup_fatal and defaults it to __libc_fatal. It replaces __libc_fatal with _startup_fatal in static executables where it is called before __libc_setup_tls is called. This header file is included in all files containing functions which are called before __libc_setup_tls is called. On Linux/i386, when PIE is enabled by default, _startup_fatal is turned into ABORT_INSTRUCTION and I386_USE_SYSENTER is defined to 0 so that "int $0x80" is used for system calls before __libc_setup_tls is called. Tested on i686 and x86-64. Without this patch, all statically-linked tests will fail on i686 when the compiler defaults to -fPIE. [BZ #21913] * csu/libc-tls.c: Include <startup.h> first.

posix: Set p{read,write}v2 to return ENOTSUP (BZ#21780)
Different than other architectures hppa-linux-gnu define different values
for ENOTSUP and EOPNOTSUPP, where the later is a Linux specific one.
This leads to tst-preadwritev{64}v2 tests failures:
$ ./testrun.sh misc/tst-preadvwritev2
error: tst-preadvwritev2-common.c:35: preadv2 failure did not set errno to ENOTSUP (223)
error: 1 test failures
The straightforward fix is to return the POSIX defined ENOTSUP on all
p{read,write}v{64}v2 implementations instead of Linux specific one.
Checked on x86_64-linux-gnu and the tst-preadwritev{64}v2 on
hppa-linux-gnu (although due the installed kernel on my testing system
the pwritev{64}v2 with an invalid flag still fails due a known kernel
issue [1]).

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].

Consistently use uintN_t not u_intN_t everywhere.

microblaze: Resolve non-relocatable branch in pt-vfork.S (BZ#21779)
The relative branch directly to __libc_vfork results in an relocation that cannot be resolved. Specifically a R_MICROBLAZE_64_PCREL relocation is created for this branch, however for MicroBlaze R_MICROBLAZE_64_PCREL type relocations symbols are not resolved. Additionally due to the branch being located in the .text section the instruction cannot be rewritten as the section is not writable, and causes a segfault at runtime when loading libpthread. To resolve this issue, ensure the branch is done using PLT. This removes the need to modify the instruction and trades the R_MICROBLAZE_64_PCREL for a more common R_MICROBLAZE_JUMP via the PLT. [BZ #21779] * sysdeps/unix/sysv/linux/microblaze/pt-vfork.S: Branch using PLT. |

tunables: Use direct syscall for access (BZ#21744)
The function maybe_enable_malloc_check, which is called by __tunables_init, calls __access_noerrno. It isn't problem when symbol is is in ld.so, which has a special version of __access_noerrno without stack protector. But when glibc is built with stack protector, maybe_enable_malloc_check in libc.a can't call the regular version of __access_noerrno with stack protector. This patch changes how Linux defines the __access_noerrno to be an inline call instead and thus preventing defining different build rules for ld/static and shared. H.J.

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. |

Miscellaneous sys/ucontext.h namespace fixes (bug 21457).
This patch fixes various miscellaneous namespace issues in sys/ucontext.h headers. Some struct tags are removed where the structs also have *_t typedef names, while other struct tags without such names are renamed to start __; the changes are noted in NEWS as they can affect C++ name mangling (although there seems to be little if any external use of these types, at least based on checking codesearch.debian.net). For powerpc, pointers to struct pt_regs (not defined in this header) are changed to point to struct __ctx(pt_regs), so in the __USE_MISC case those struct fields continue to point to the existing struct pt_regs type for maximum compatibility, while when that's a namespace issue they point to a struct __pt_regs type which is always an incomplete struct. Tested for affected architectures with build-many-glibcs.py. [BZ #21457] * sysdeps/unix/sysv/linux/m68k/sys/ucontext.h (fpregset_t): Remove struct tag. * sysdeps/unix/sysv/linux/mips/sys/ucontext.h (fpregset_t): Likewise. * sysdeps/unix/sysv/linux/nios2/sys/ucontext.h (mcontext_t): Likewise. * sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h (pt_regs): Declare struct type with __ctx.

Add float128 support for ia64.
This patch enables float128 support for ia64, so that all the configurations where GCC supports _Float128 / __float128 as an ABI-distinct type now have glibc support as well. bits/floatn.h declares the support to be available for GCC 4.4 and later, which is when the libgcc support was added. The removal of sysdeps/ia64/fpu/k_rem_pio2.c is because the generic k_rem_pio2.c defines a function required by the float128 code. Tested (compilation only) with build-many-glibcs.py for ia64 (GCC 6 and GCC 7). Given how long it is since libm-test-ulps has been updated for ia64, I think truncating the file and regenerating it from scratch would be a good idea when doing a regeneration to add float128 ulps. I expect various ia64 libm issues (at least some already filed in Bugzilla) to result in test failures even after ulps regeneration, but hopefully the float128 code will pass tests as it's the same as used on other architectures. * sysdeps/ia64/Implies: Add ieee754/float128. * sysdeps/ia64/bits/floatn.h: New file. * sysdeps/ia64/float128-abi.h: Likewise. * manual/math.texi (Mathematics): Document support for _Float128 on ia64. * sysdeps/ia64/Makefile [$(subdir) = math] (CPPFLAGS): Append to Makefile variable. * sysdeps/ia64/fpu/e_sqrtf128.c: New file. * sysdeps/ia64/fpu/k_rem_pio2.c: Remove file. * sysdeps/ia64/fpu/sfp-machine.h: New file.

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.

Add float128 support for x86_64, x86.
This patch enables float128 support for x86_64 and x86. All GCC versions that can build glibc provide the required support, but since GCC 6 and before don't provide __builtin_nanq / __builtin_nansq, sNaN tests and some tests of NaN payloads need to be disabled with such compilers (this does not affect the generated glibc binaries at all, just the tests). bits/floatn.h declares float128 support to be available for GCC versions that provide the required libgcc support (4.3 for x86_64, 4.4 for i386 GNU/Linux, 4.5 for i386 GNU/Hurd); compilation-only support was present some time before then, but not really useful without the libgcc functions. fenv_private.h needed updating to avoid trying to put _Float128 values in registers. I make no assertion of optimality of the math_opt_barrier / math_force_eval definitions for this case; they are simply intended to be sufficient to work correctly. Tested for x86_64 and x86, with GCC 7 and GCC 6. (Testing for x32 was compilation tests only with build-many-glibcs.py to verify the ABI baseline updates. I have not done any testing for Hurd, although the float128 support is enabled there as for GNU/Linux.) * sysdeps/i386/Implies: Add ieee754/float128. * sysdeps/x86_64/Implies: Likewise. * sysdeps/x86/bits/floatn.h: New file. * sysdeps/x86/float128-abi.h: Likewise. * manual/math.texi (Mathematics): Document support for _Float128 on x86_64 and x86. * sysdeps/i386/fpu/fenv_private.h: Include <bits/floatn.h>.

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.

This patch also adds the implementation of sqrtf128 for powerpc64le, since it is not implemented in libgcc. The sfp-machine.h header is taken from libgcc. Tested for powerpc64le (GCC 6.2 and GCC 7.1), powerpc64 and s390x. * manual/math.texi (Mathematics): Mention the enabling of float128 for powerpc64le. * sysdeps/powerpc/bits/floatn.h: New file. * sysdeps/powerpc/fpu/libm-test-ulps: Regenerated. * sysdeps/powerpc/fpu/math_private.h: (__ieee754_sqrtf128): New inline override. * sysdeps/powerpc/powerpc64le/Implies-before: New file. * sysdeps/powerpc/powerpc64le/Makefile: New file. * sysdeps/powerpc/powerpc64le/fpu/e_sqrtf128.c: New file. * sysdeps/powerpc/powerpc64le/fpu/sfp-machine.h: New file. * sysdeps/powerpc/powerpc64le/power9/fpu/e_sqrtf128.c: New file. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc-le.abilist: Updated. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm-le.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64le/float128-abi.h: New file. |

Clean pthread functions namespaces for C11 threads
This patch adds internal definition (through {libc_}hidden_{proto,def}) and
also change some strong to weak alias for symbols that might be used by C11
threads implementations.
The patchset should not change libc/libpthread functional, although object
changes are expected (since now internal symbols are used instead) and final
exported symbols through GLIBC_PRIVATE is also expanded (to cover libpthread
usage of __mmap{64}, __munmap, __mprotect).

Fix tile SA_* conditions for POSIX.1:2008 (bug 21622).
As shown by conform/ tests once the remaining namespace issues are fixed, the tile bits/sigaction.h fails to declare SA_RESETHAND, SA_RESTART and SA_NODEFER for non-XSI POSIX.1:2008 as other versions do. Those constants were moved from XSI to Base in the 2008 edition of POSIX. This patch fixes the conditions to match other versions of this header. Tested (compilation only) for tilegx-linux-gnu with build-many-glibcs.py. [BZ #21622] * sysdeps/unix/sysv/linux/tile/bits/sigaction.h (SA_RESTART): Define for [__USE_UNIX98 || __USE_XOPEN2K8], not [__USE_UNIX98 || __USE_MISC]. (SA_NODEFER): Likewise.

Factor out shared definitions from bits/signum.h.
Many of the things defined by bits/signum.h are invariant across all supported operating systems. This patch factors out all of them to a new header bits/signum-generic.h, which each bits/signum.h will include and then override whichever things need adjustment. Normally that will mean, at most, adding or changing a few signal numbers. A user-visible side effect is that the obsolete signal constant SIGUNUSED (which is an alias for SIGSYS on all platforms that define it) is no longer exposed by any version of bits/signum.h. A side effect only relevant to glibc hackers is that _NSIG is now defined in terms of __SIGRTMAX, instead of the other way around. This is because __SIGRTMAX varies from platform to platform, but _NSIG==__SIGRTMAX+1 is true universally. If your platform doesn't support realtime signals, leave __SIGRTMAX equal to __SIGRTMIN. I also added a Linux-specific test to make sure that our signal constants match the ones in <asm/signal.h>, since we can't use that header (it's not even vaguely namespace-clean). * bits/signum-generic.h: Renamed from bits/signum.h. Add proper multiple include guard and misuse check. Define __SIGRTMIN = __SIGRTMAX = 32, and define _NSIG = __SIGRTMAX+1. Move definition of SIGIO to "archaic names for compatibility" section. * bits/signum.h: New file which just includes bits/signum-generic.h. * sysdeps/unix/bsd/bits/signum.h * sysdeps/unix/sysv/linux/bits/signum.h * sysdeps/unix/sysv/linux/alpha/bits/signum.h * sysdeps/unix/sysv/linux/hppa/bits/signum.h * sysdeps/unix/sysv/linux/mips/bits/signum.h * sysdeps/unix/sysv/linux/sparc/bits/signum.h Just include <bits/signum-generic.h> and then add or adjust signal constants. Do not define SIGUNUSED, SIGRTMIN, or SIGRTMAX. * signal/Makefile: Install bits/signum-generic.h. * signal/signal.h: Define SIGRTMIN and SIGRTMAX here. * sysdeps/generic/siglist.h: SIGSYS and SIGWINCH are universal.

Consolidate Linux openat implementation
This patch consolidates the open Linux syscall implementation on
sysdeps/unix/sysv/linux/open{64}.c. The changes are:
1. Remove wordsize-64 openat{64}.
2. For architetures that define __OFF_T_MATCHES_OFF64_T openat64
will be default one with alias to required symbols. Otherwise
openat64 will pass the required O_LARGEFILE flag on syscall.
Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32,

tunables: Add IFUNC selection and cache sizes
The current IFUNC selection is based on microbenchmarks in glibc. It should give the best performance for most workloads. But other choices may have better performance for a particular workload or on the hardware which wasn't available at the selection was made. The environment variable, GLIBC_TUNABLES=glibc.tune.ifunc=-xxx,yyy,-zzz...., can be used to enable CPU/ARCH feature yyy, disable CPU/ARCH feature yyy and zzz, where the feature name is case-sensitive and has to match the ones in cpu-features.h. It can be used by glibc developers to override the IFUNC selection to tune for a new processor or improve performance for a particular workload. It isn't intended for normal end users. NOTE: the IFUNC selection may change over time. Please check all multiarch implementations when experimenting. Also, GLIBC_TUNABLES=glibc.tune.x86_non_temporal_threshold=NUMBER is provided to set threshold to use non temporal store to NUMBER, GLIBC_TUNABLES=glibc.tune.x86_data_cache_size=NUMBER to set data cache size, GLIBC_TUNABLES=glibc.tune.x86_shared_cache_size=NUMBER to set shared cache size. * elf/dl-tunables.list (tune): Add ifunc, x86_non_temporal_threshold, x86_data_cache_size and x86_shared_cache_size. * manual/tunables.texi: Document glibc.tune.ifunc, glibc.tune.x86_data_cache_size, glibc.tune.x86_shared_cache_size and glibc.tune.x86_non_temporal_threshold. * sysdeps/unix/sysv/linux/x86/dl-sysdep.c: New file. * sysdeps/x86/cpu-tunables.c: Likewise. * sysdeps/x86/cacheinfo.c (init_cacheinfo): Check and get data cache size, shared cache size and non temporal threshold from cpu_features. * sysdeps/x86/cpu-features.c [HAVE_TUNABLES] (TUNABLE_NAMESPACE): New.

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.

Define struct rusage in sys/wait.h when required (bug 21575).
Some older standards (XPG4.2 through POSIX.1:2001, XSI only) require sys/wait.h to include the definition of struct rusage. This is missing in glibc. This patch adds the required definition. struct rusage is moved to a new header bits/types/struct_rusage.h to avoid bringing in the whole of sys/resource.h (although the standards in question do allow the whole of sys/resource.h to be brought in). In the five bits/resource.h headers, the only variation between the definitions of struct rusage is that the sysdeps/unix/sysv/linux version is prepared for x32 (by having anonymous unions with __syscall_slong_t fields) and the others are not. Thus, this version is suitable for use generically (everything other than x32 simply has __syscall_slong_t the same as long int, so there are no API or ABI changes involved, and anonymous unions are already a required language feature for glibc headers elsewhere), and this patch uses it as a base for the single implementation of bits/types/struct_rusage.h. Tested for x86_64, and with build-many-glibcs.py. [BZ #21575] * resource/bits/types/struct_rusage.h: New file. * include/bits/types/struct_rusage.h: Likewise. * bits/resource.h (struct rusage): Include <bits/types/struct_rusage.h> instead of defining here. * sysdeps/unix/sysv/linux/bits/resource.h (struct rusage): Likewise. * sysdeps/unix/sysv/linux/alpha/bits/resource.h (struct rusage): Likewise. * sysdeps/unix/sysv/linux/mips/bits/resource.h (struct rusage): Likewise. * sysdeps/unix/sysv/linux/sparc/bits/resource.h (struct rusage): Likewise. * resource/Makefile (headers): Add bits/types/struct_rusage.h. * posix/sys/wait.h [__USE_XOPEN_EXTENDED && !__USE_XOPEN2K8]: Include <bits/types/struct_rusage.h> |

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. |

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

up that code.
A microbenchmark doing "syscall(__NR_getpid);" in a loops gets faster
by ~12%.

Remove __need macros from errno.h (__need_Emath, __need_error_t).
This is fairly complicated, not because the users of __need_Emath and __need_error_t have complicated requirements, but because the core changes had a lot of fallout. __need_error_t exists for gnulib compatibility in argz.h and argp.h. error_t itself is a Hurdism, an enum containing all the E-constants, so you can do 'p (error_t) errno' in gdb and get a symbolic value. argz.h and argp.h use it for function return values, and they want to fall back to 'int' when that's not available. There is no reason why these nonstandard headers cannot just go ahead and include all of errno.h; so we do that. __need_Emath is defined only by .S files; what they _really_ need is for errno.h to avoid declaring anything other than the E-constants (e.g. 'extern int __errno_location(void);' is a syntax error in assembly language). This is replaced with a check for __ASSEMBLER__ in errno.h, plus a carefully documented requirement for bits/errno.h not to define anything other than macros. That in turn has the consequence that bits/errno.h must not define errno - fortunately, all live ports use the same definition of errno, so I've moved it to errno.h. The Hurd bits/errno.h must also take care not to define error_t when __ASSEMBLER__ is defined, which involves repeating all of the definitions twice, but it's a generated file so that's okay. * stdlib/errno.h: Remove __need_Emath and __need_error_t logic. Reorganize file. Declare errno here. When __ASSEMBLER__ is defined, don't declare anything other than the E-constants. * include/errno.h: Change conditional for exposing internal declarations to (not _ISOMAC and not __ASSEMBLER__). * bits/errno.h: Remove logic for __need_Emath. Document requirements for a port-specific bits/errno.h. * sysdeps/unix/sysv/linux/bits/errno.h * sysdeps/unix/sysv/linux/alpha/bits/errno.h * sysdeps/unix/sysv/linux/hppa/bits/errno.h * sysdeps/unix/sysv/linux/mips/bits/errno.h * sysdeps/unix/sysv/linux/sparc/bits/errno.h: Add multiple-include guard and check against improper inclusion. Remove __need_Emath logic. Don't declare errno here. Ensure all constants are defined as simple integer literals. Consistent formatting. * sysdeps/mach/hurd/errnos.awk: Likewise. Only define error_t and enum __error_t_codes if __ASSEMBLER__ is not defined. * sysdeps/mach/hurd/bits/errno.h: Regenerate. * argp/argp.h, string/argz.h: Don't define __need_error_t before including errno.h. * sysdeps/i386/i686/fpu/multiarch/s_cosf-sse2.S * sysdeps/i386/i686/fpu/multiarch/s_sincosf-sse2.S * sysdeps/i386/i686/fpu/multiarch/s_sinf-sse2.S * sysdeps/x86_64/fpu/s_cosf.S * sysdeps/x86_64/fpu/s_sincosf.S * sysdeps/x86_64/fpu/s_sinf.S: Just include errno.h; don't define __need_Emath or include bits/errno.h directly. |

Remove __need_IOV_MAX and __need_FOPEN_MAX.
__need_FOPEN_MAX wasn't being used anywhere. __need_IOV_MAX was more complicated; the basic deal is that sys/uio.h wants to define a constant named UIO_MAXIOV and bits/xopen_lim.h wants to define a constant named IOV_MAX, with the same meaning. For no apparent reason this was being handled via bits/stdio_lim.h -- stdio.h is NOT supposed to define IOV_MAX -- and some mess in Makerules. Also, bits/uio.h on Linux was being used as a dumping ground for extension functions. So now we have bits/uio_lim.h, which defines __IOV_MAX. bits/xopen_lim.h and sys/uio.h use that to define their respective constants. We also now have bits/uio-ext.h, which is the official Proper Home for extensions to sys/uio.h. bits/uio.h is removed, and stdio_lim.h doesn't define IOV_MAX at all. * bits/uio_lim.h, sysdeps/unix/sysv/linux/bits/uio_lim.h * bits/uio-ext.h, sysdeps/unix/sysv/linux/bits/uio-ext.h: New file. * bits/uio.h, sysdeps/unix/sysv/linux/bits/uio.h: Delete file. * include/bits/xopen_lim.h: Use bits/uio_lim.h to get the value for IOV_MAX. * misc/Makefile: Install bits/uio-ext.h and bits/uio_lim.h.

mips: Fix store/load gp registers to/from ucontext_t
General purpose registers in mcontext_t structure are 8 bytes long for both MIPS32/MIPS64. get/set/make/swap context implementations for MIPS O32 incorrectly assume that general purpose registers in this structure are 4 bytes long. This patch is fixing that. Tested for MIPS O32 LE and BE. Compared objdump of modified functions for mips n32 and mips n64. [BZ #21548] * sysdeps/unix/sysv/linux/mips/getcontext.S: Define MCONTEXT_SZGREG as 8 and use it when copying general purpose registers. * sysdeps/unix/sysv/linux/mips/makecontext.S: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/Makefile: Include new test for mips o32. * sysdeps/unix/sysv/linux/mips/mips32/bug-getcontext-mips-gp.c: Added new test for mips o32. * sysdeps/unix/sysv/linux/mips/setcontext.S: Define MCONTEXT_SZGREG as 8 and use it when copying general purpose registers. * sysdeps/unix/sysv/linux/mips/swapcontext.S: Likewise. |

Remove __need_schedparam and __cpu_set_t_defined.
bits/sched.h has logic to expose only an impl-namespace variant of struct sched_param (i.e. struct __sched_param), but nothing uses it, and the only header that includes bits/sched.h is sched.h. The __need_schedparam logic can therefore be removed. bits/sched.h also has a great deal of code relating to cpu_set_t objects that was *almost* the same between the two versions of bits/sched.h in the tree; a little spelunking indicated that this is because some bug fixes got applied to the Linux-specific bits/sched.h but not the generic one. Introduce a new header, bits/cpu-set.h, containing the version of that code with the bugfixes, have sched.h include it directly, and delete all of the code from both versions of bits/sched.h. Also remove the unnecessary name mangling in the definition of struct sched_param -- POSIX specifies a field 'sched_priority', so there is no reason to define it as '__sched_priority' and then paper over that with a macro. (Just in case someone was using the internal name, 'sched_priority' remains a macro defined to expand to itself, and '__sched_priority' now expands to 'sched_priority'.) Finally, as long as I'm touching these files anyway, merge new constants from linux/sched.h into the Linux bits/sched.h. * bits/sched.h: Remove __need_schedparam logic and replace with a normal multiple-include guard. Change field name in struct sched_param from __sched_priority to sched_priority. Delete everything under #ifndef __cpu_set_t_defined. * sysdeps/unix/sysv/linux/bits/sched.h: Likewise. Also sync with kernel sched.h, adding SCHED_ISO and SCHED_DEADLINE constants. * posix/sched.h: Include bits/cpu-set.h as well as bits/sched.h. For compatibility, #define sched_priority to itself, and #define __sched_priority as sched_priority. * posix/bits/cpu-set.h: New file containing, verbatim, the code that was under #ifndef __cpu_set_t_defined in sysdeps/unix/sysv/linux/bits/sched.h. * include/bits/cpu-set.h: New wrapper. * posix/Makefile: Install bits/cpu-set.h. |

powerpc: add sysconf support for cache geometries
There is currently no "cross-platform" (x86 and POWER) support for determining the cacheline size. This patch adds support to sysconf() to correctly report cacheline sizes based on the information in the auxilliary vector. Thus, using sysconf() is a cross-platform (x86 and POWER) solution for determining cacheline sizes. Support is added (on powerpc) for: _SC_LEVEL1_ICACHE_SIZE _SC_LEVEL1_ICACHE_ASSOC _SC_LEVEL1_ICACHE_LINESIZE _SC_LEVEL1_DCACHE_SIZE _SC_LEVEL1_DCACHE_ASSOC _SC_LEVEL1_DCACHE_LINESIZE _SC_LEVEL2_CACHE_SIZE _SC_LEVEL2_CACHE_ASSOC _SC_LEVEL2_CACHE_LINESIZE _SC_LEVEL3_CACHE_SIZE _SC_LEVEL3_CACHE_ASSOC _SC_LEVEL3_CACHE_LINESIZE * sysdeps/unix/sysv/linux/powerpc/sysconf.c: New file. Add powerpc-specific overrides for L1, L2, L3 CACHE_SIZEs, CACHE_ASSOCs, and CACHE_LINESIZEs, retrieving from auxv. * sysdeps/unix/sysv/linux/powerpc/test-powerpc-linux-sysconf.c: New file. Invoke newly supported sysconf values for powerpc, and report results. If none are supported, report so. * sysdeps/unix/sysv/linux/powerpc/Makefile (tests): Add new test, tst-sysconf. |

Fix waitid namespace (bug 21561).
In sys/wait.h, waitid and associated constants and types are UX-shaded in XPG4.2 (so not in XPG4), and XSI-shaded in POSIX before 2008, so should be appropriately conditional in the headers. This patch fixes the conditionals accordingly. (WCONTINUED is actually still XSI-shaded in POSIX.1:2008, but W* is also reserved there without XSI-shading, so nothing special needs to be done about the conditionals on WCONTINUED to conform to POSIX.1:2008 namespace rules.)

Update nios2, sparc32 localplt.data files for recent GCC change.
A recent GCC change to expand floating-point classification built-in functions inline using integer rather than floating-point arithmetic in some cases resulted in localplt test failures for nios2 and sparc32 <https://sourceware.org/ml/libc-testresults/2017-q2/msg00320.html>. This patch updates the localplt.data files in question to mark the relevant symbols as optional / add a new optional symbol. (The GCC patch has been reverted because of other problems it caused, but one can assume it will be applied again, without changes that would affect the PLT entries generated, once those issues have been resolved.) Tested with build-many-glibcs.py. * sysdeps/unix/sysv/linux/nios2/localplt.data (__gtdf2): Mark libc.so PLT entry optional. (__gtsf2): Likewise. (__unorddf2): Likewise.

Remove check for NULL buffer passed to `ptsname_r'
`ptsname_r' is declared in stdlib.h to only accept a `nonnull' second argument and therefore GCC may choose to make optimizations based on the assumption that this argument is NULL. This means that potentially, GCC can optimize away the NULL check at some point in the future. Since this is a programming interface, we might as well remove the NULL check ourselves. This also warrants a change to the `ptsname_r' manual page that must be submitted to the corresponding mailing list. In addition, remove the NULL buffer test in login/tst-ptsname.c. |

aarch64: Allow overriding HWCAP_CPUID feature check using HWCAP_MASK
Now that LD_HWCAP_MASK (or glibc.tune.hwcap_mask) is read early enough to influence cpu feature check in aarch64, use it to influence multiarch selection. Setting LD_HWCAP_MASK such that it clears HWCAP_CPUID will now disable multiarch for the binary. HWCAP_CPUID is also now set in HWCAP_IMPORTANT so that it is set by default. With this patch, this feature is only usable with dyanmically linked binaries because LD_HWCAP_MASK is not read for static binaries. A future patch fixes that. * sysdeps/unix/sysv/linux/aarch64/cpu-features.c (init_cpu_features): Use glibc.tune.hwcap_mask. * sysdeps/unix/sysv/linux/aarch64/dl-procinfo.h: New file. |

Optimize generic spinlock code and use C11 like atomic macros.
This patch optimizes the generic spinlock code. The type pthread_spinlock_t is a typedef to volatile int on all archs. Passing a volatile pointer to the atomic macros which are not mapped to the C11 atomic builtins can lead to extra stores and loads to stack if such a macro creates a temporary variable by using "__typeof (*(mem)) tmp;". Thus, those macros which are used by spinlock code - atomic_exchange_acquire, atomic_load_relaxed, atomic_compare_exchange_weak - have to be adjusted. According to the comment from Szabolcs Nagy, the type of a cast expression is unqualified (see http://www.open-std.org/jtc1/sc22/wg14/www/docs/dr_423.htm): __typeof ((__typeof (*(mem)) *(mem)) tmp; Thus from spinlock perspective the variable tmp is of type int instead of type volatile int. This patch adjusts those macros in include/atomic.h. With this construct GCC >= 5 omits the extra stores and loads. The atomic macros are replaced by the C11 like atomic macros and thus the code is aligned to it. The pthread_spin_unlock implementation is now using release memory order instead of sequentially consistent memory order. The issue with passed volatile int pointers applies to the C11 like atomic macros as well as the ones used before. I've added a glibc_likely hint to the first atomic exchange in pthread_spin_lock in order to return immediately to the caller if the lock is free. Without the hint, there is an additional jump if the lock is free. I've added the atomic_spin_nop macro within the loop of plain reads. The plain reads are also realized by C11 like atomic_load_relaxed macro. The new define ATOMIC_EXCHANGE_USES_CAS determines if the first try to acquire the spinlock in pthread_spin_lock or pthread_spin_trylock is an exchange or a CAS. This is defined in atomic-machine.h for all architectures. The define SPIN_LOCK_READS_BETWEEN_CMPXCHG is now removed. There is no technical reason for throwing in a CAS every now and then, and so far we have no evidence that it can improve performance. If that would be the case, we have to adjust other spin-waiting loops elsewhere, too! Using a CAS loop without plain reads is not a good idea on many targets and wasn't used by one. Thus there is now no option to do so. Architectures are now using the generic spinlock automatically if they do not provide an own implementation. Thus the pthread_spin_lock.c files in sysdeps folder are deleted. ChangeLog: * NEWS: Mention new spinlock implementation. * include/atomic.h: (__atomic_val_bysize): Cast type to omit volatile qualifier. (atomic_exchange_acq): Likewise.

x86-64: Update LO_HI_LONG for p{readv,writev}{64}v2
The kernel interface for p{readv,writev}{64}v is
(unsigned long fd, {const }struct iovec *iov, unsigned long vlen,
unsigned long pos_l, unsigned long pos_h)
Except for targets which define __ARCH_WANT_COMPAT_SYS_PREADV64 and
__ARCH_WANT_COMPAT_SYS_PWRITEV64,
(unsigned long fd, {const }struct iovec *iov, unsigned long vlen,
off64_t pos)
is used for p{readv,writev}{64}v. X32 is the only such target. The
LO_HI_LONG macro is used to pass offset to the pos_l and pos_h pair.
Since pos_h is ignored when size of offset == sizeof of pos_l, x86-64
has
#define LO_HI_LONG(val) (val)
But the kernel interface for p{readv,writev}{64}v2 is
(unsigned long fd, {const }struct iovec *iov, unsigned long vlen,
unsigned long pos_l, unsigned long pos_h, int flags)
Except for targets which define __ARCH_WANT_COMPAT_SYS_PREADV64V2 and
__ARCH_WANT_COMPAT_SYS_PWRITEV64V2,
(unsigned long fd, {const }struct iovec *iov, unsigned long vlen,
off64_t pos, int flags)
is used for p{readv,writev}{64}v2. X32 is the only such target. Update
x86-64 LO_HI_LONG to pass 0 as the high part of the offset argument for
p{readv,writev}{64}v2 and define a different LO_HI_LONG for x32 to only
pass one argument for offset.
Tested on x32 and x86-64.
* sysdeps/unix/sysv/linux/x86_64/sysdep.h (LO_HI_LONG): Pass
0 as the high part of offset.
* sysdeps/unix/sysv/linux/x86_64/x32/sysdep.h (LO_HI_LONG): New.

Define SIG_HOLD for XPG4 (bug 21538).

Because of other header bugs, this does not allow any XFAILs to be removed (however, the XPG4/signal.h/conform XFAIL only depends on a few such straightforward header bugs, not on the more complicated to fix ucontext_t issues, as ucontext_t isn't included in signal.h in XPG4).

Fix struct sigaltstack namespace (bug 21517).
glibc defines the stack_t type with the tag struct sigaltstack. This is not permitted by POSIX; sigaltstack is only reserved with file scope in the namespace of ordinary identifiers, not the tag namespace, and in the case where stack_t is obtained from ucontext.h rather than signal.h, it's not reserved with file scope at all. This patch removes the tag accordingly and updates uses in glibc of struct sigaltstack. This is similar to the removal of the "struct siginfo" tag a few years ago: C++ name mangling changes are an unavoidable consequence. A NEWS item is added to note the changed mangling. There is inevitably some risk of breaking builds of anything that relies on the struct sigaltstack name (though the first few hits I looked at from codesearch.debian.net generally seemed to involve code that could use the stack_t name conditionally, so depending on how they determine the conditionals they may work with glibc not defining the struct tag anyway). Tested for x86_64 and x86, and with build-many-glibcs.py. [BZ #21517] * bits/types/stack_t.h (stack_t): Remove struct tag. * sysdeps/unix/sysv/linux/bits/types/stack_t.h (stack_t): Likewise. * sysdeps/unix/sysv/linux/mips/bits/types/stack_t.h (stack_t): Likewise. * debug/segfault.c (install_handler): Use stack_t instead of struct sigaltstack. * hurd/hurd/signal.h (struct hurd_sigstate): Likewise. * hurd/trampoline.c (_hurd_setup_sighandler): Likewise. * include/signal.h (__sigaltstack): Likwise. * signal/sigaltstack.c (__sigaltstack): Likewise. * signal/signal.h (sigaltstack): Likewise. * sysdeps/mach/hurd/i386/signal-defines.sym (SIGALTSTACK__SS_SP__OFFSET): Likewise.

Add shim header for bits/syscall.h.
On Linux-based configurations, bits/syscall.h is a generated file. To avoid build-ordering problems, the Linux sys/syscall.h only includes bits/syscall.h if _LIBC is not defined. After the _ISOMAC-testsuite changes, this means any test case that includes sys/syscall.h tries to pull in bits/syscall.h. This would be fine, because it'll definitely have been generated by the time we start compiling tests, except that the generated <builddir>/misc/bits/syscall.h is not visible in the include path, because nothing needed it till now. So we either get the bits/syscall.h from the host system, or the build fails. The fix is simple: add a shim header for bits/syscall.h. I put it in sysdeps/unix/sysv/linux/include instead of the top-level include/ because bits/syscall.h doesn't exist at all on other configurations as far as I can tell. This is known to affect nptl/tst-cond2[45]. Thanks to John David Anglin for noticing the problem.

Fix more namespace issues in sys/ucontext.h (bug 21457).
Continuing the fixes for namespace issues in sys/ucontext.h, this patch moves various symbols into the implementation namespace in the absence of __USE_MISC. As with previous changes, it is nonexhaustive, just covering more straightforward cases. Structure fields are generally changed to have a prefix __ in the absence of __USE_MISC, via a macro __ctx (used without a space before the open parenthesis, since the result is a single identifier). Various macros such as NGREG also have leading __ added. No changes are made to structure tags (and thus to C++ name mangling), except that in the (unused) file sysdeps/i386/sys/ucontext.h, structures defined inside other structures as the type for a field have their tags removed in the non-__USE_MISC case (those structure tags would not in any case have been visible in C++, because in C++ the scope of such a tag is limited to the containing structure). No changes are made to the contents of bits/sigcontext.h, or to whether it is included. Because of remaining namespace issues, this patch does not yet fix the bug or allow any XFAILs to be removed. Tested for x86_64 and x86, and with build-many-glibcs.py. [BZ #21457] * sysdeps/arm/sys/ucontext.h (NGREG): Rename to __NGREG and define NGREG to __NGREG if [__USE_MISC].

Avoid tickling a linker bug from microblaze pt-vfork.S.
libpthread used to have its own vfork implementation that differed from libc's only in having a pointless micro-optimization. There is no longer any use to having a separate copy in libpthread, but the historical ABI requires a compatibility shim. microblaze was trying to be slightly too clever about how it did this, and tickled a linker bug. The linker bug should get fixed eventually, but there's no reason for us to keep tickling it in the meantime. This doesn't reuse the generic pt-vfork.c because microblaze doesn't have IFUNC support yet, and it doesn't reuse aarch64/pt-vfork.c because that fails to generate a tailcall (with GCC 7.1.1). * sysdeps/unix/sysv/linux/microblaze/pt-vfork.S: Don't include alpha/pt-vfork.S. Provide own compat shim for vfork and __vfork. * sysdeps/unix/sysv/linux/microblaze/vfork.S: Add __libc_vfork alias. * sysdeps/unix/sysv/linux/microblaze/localplt.data: libpthread.so no longer references __errno_location. |

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.

Delay initialization of CPU features struct in static binaries
Allow the CPU features structure set up to be overridden by tunables by delaying it to until after tunables are initialized. The initialization is already delayed in dynamically linked glibc, it is only in static binaries that the initialization is set early to allow it to influence IFUNC relocations that happen in libc-start. It is a bit too early however and there is a good place between tunables initialization and IFUNC relocations where this can be done. Verified that this does not regress the testsuite. * csu/libc-start.c [!ARCH_INIT_CPU_FEATURES]: Define ARCH_INIT_CPU_FEATURES. (LIBC_START_MAIN): Call it. * sysdeps/unix/sysv/linux/aarch64/libc-start.c (__libc_start_main): Remove. (ARCH_INIT_CPU_FEATURES): New macro. * sysdeps/x86/libc-start.c (__libc_start_main): Remove.

Add reallocarray function
The reallocarray function is an extension from OpenBSD. It is an integer-overflow-safe replacement for realloc(p, X*Y) and malloc(X*Y) (realloc(NULL, X*Y)).

Fix sys/ucontext.h namespace from signal.h etc. inclusion (bug 21457).
The various sys/ucontext.h headers include <signal.h> and all the headers split out of <bits/sigstack.h>. (Except that the powerpc version does not include <signal.h>.) None of the standard versions defining ucontext.h require or permit such inclusions; rather, they all say that the stack_t and sigset_t types from signal.h are defined. This patch fixes the headers to include just the bits/ headers for those types (and the existing includes of bits/sigcontext.h). Since bits/types/sigset_t.h is now being included instead of bits/types/__sigset_t.h, __sigset_t uses in the headers are replaced by direct use of the public sigset_t type. sysdeps/unix/sysv/linux/x86/bits/sigcontext.h was relying on the prior inclusion of <signal.h> to define types such as __uint32_t, so gets a bits/types.h include added to provide those types. Although one could keep some or all of the includes under a __USE_MISC conditional, that seems unnecessary to me, especially given the lack of a <signal.h> include in the powerpc version meaning that portable programs already cannot rely on such an include. Tested for x86_64 and x86, and with build-many-glibcs.py. As with other such fixes, more namespace issues remain so this does not permit any XFAILs to be removed or bugs to be closed.

The types affected are __sig_atomic_t, sig_atomic_t, __sigset_t, sigset_t, sigval_t, sigevent_t, and siginfo_t. __sig_atomic_t is a scalar, so it's now directly available from bits/types.h. The others get bits/types/ headers. Side effects include: There have been small changes to which non-signal headers expose which subset of the signal-related types. A couple of architectures' nested siginfo_t fields had to be renamed to prevent undesired macro expansion. Internal code that wants to manipulate signal masks must now include <sigsetops.h> (which is not installed) and should be aware that __sigaddset, __sigandset, __sigdelset, __sigemptyset, and __sigorset no longer return a value (unlike the public API). Relatedly, the public signal.h no longer declares any of those functions. The obsolete sigmask() macro no longer has a system-specific definition -- in the cases where it matters, it didn't work anyway. New Linux architectures should create bits/siginfo-arch.h and/or bits/siginfo-consts-arch.h to customize their siginfo_t, rather than duplicating everything in bits/siginfo.h (which no longer exists). Add new __SI_* macros if necessary. Ports to other operating systems are strongly encouraged to generalize this scheme further. * bits/sigevent-consts.h * bits/siginfo-consts.h * bits/types/__sigset_t.h * bits/types/sigevent_t.h * bits/types/siginfo_t.h * sysdeps/unix/sysv/linux/bits/sigevent-consts.h * sysdeps/unix/sysv/linux/bits/siginfo-consts.h * sysdeps/unix/sysv/linux/bits/types/__sigset_t.h * sysdeps/unix/sysv/linux/bits/types/sigevent_t.h * sysdeps/unix/sysv/linux/bits/types/siginfo_t.h: New system-dependent bits headers. * sysdeps/unix/sysv/linux/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/bits/siginfo-consts-arch.h * sysdeps/unix/sysv/linux/ia64/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/ia64/bits/siginfo-consts-arch.h * sysdeps/unix/sysv/linux/mips/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/sparc/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/tile/bits/siginfo-arch.h * sysdeps/unix/sysv/linux/tile/bits/siginfo-consts-arch.h * sysdeps/unix/sysv/linux/x86/bits/siginfo-arch.h: New Linux-only system-dependent bits headers. * signal/bits/types/sig_atomic_t.h * signal/bits/types/sigset_t.h * signal/bits/types/sigval_t.h: New non-system-dependent bits headers. * sysdeps/generic/sigsetops.h * sysdeps/unix/sysv/linux/sigsetops.h: New internal headers. * include/bits/types/sig_atomic_t.h * include/bits/types/sigset_t.h * include/bits/types/sigval_t.h: New wrappers. * signal/sigsetops.h * bits/siginfo.h * bits/sigset.h * sysdeps/unix/sysv/linux/bits/siginfo.h * sysdeps/unix/sysv/linux/bits/sigset.h * sysdeps/unix/sysv/linux/ia64/bits/siginfo.h * sysdeps/unix/sysv/linux/mips/bits/siginfo.h * sysdeps/unix/sysv/linux/s390/bits/siginfo.h * sysdeps/unix/sysv/linux/sparc/bits/siginfo.h * sysdeps/unix/sysv/linux/tile/bits/siginfo.h * sysdeps/unix/sysv/linux/x86/bits/siginfo.h: Deleted. * signal/Makefile, sysdeps/unix/sysv/linux/Makefile: Update lists of installed headers. * posix/bits/types.h: Define __sig_atomic_t here. * signal/signal.h: Use the new bits headers; no need to handle __need_sig_atomic_t nor __need_sigset_t.

Split up bits/sigstack.h.
bits/sigstack.h contains four things: the legacy struct sigstack type, the preferred stack_t type, the SS_* enum values and macros for signal stack sizes. These vary in different ways between glibc configurations; in particular, the stack sizes vary much more than any of the other pieces. Furthermore, these pieces have different standard namespace rules for when they should be visible (not currently visible in conform/ results both because the relevant tests are XFAILed for sys/ucontext.h namespace issues, and because some of the expectations are incorrect in the same way as the headers, e.g. neither expectations nor headers reflect that current POSIX no longer has either the sigstack function or the sigstack structure). To reduce duplication of identical definitions, and facilitate namespace fixes without requiring the same feature test macro conditions to be repeated in many versions of the same header, this patch splits bits/sigstack.h up into four headers. It keeps the stack size macros, while new bits/types/struct_sigstack.h, bits/types/stack_t.h and bits/ss_flags.h are added for the other pieces. bits/types/struct_sigstack.h is the same everywhere, bits/types/stack_t.h has three variants different in the order of the structure elements (generic = MIPS Linux, and other Linux), and bits/ss_flags.h has generic and Linux variants. This patch includes the new headers everywhere that included <bits/sigstack.h>, so should cause no difference to what any public header defines. Subsequent namespace fixes would then remove or condition some of those includes. There should be no conflicts with Zack's changes to signal.h types, beyond the trivial conflict of both making additions to signal/Makefile's headers list; the two patches affect disjoint sets of types and other definitions.

posix: Fix and simplify default p{read,write}v implementation
Currently all architectures but microblaze use wire-up syscall for
p{readv,write}v. Microblaze still uses the syscall emulation using
sysdep/posix/p{readv,writev}.c and it was reported in some ocasions
[1] [2] that it might have some issues with some linux specific
usage (mainly with O_DIRECT and the alignment requirement).
Although it is not an issue for virtually all the system, this
patch refactors the sysdeps/posix p{read,write}v syscall to avoid
such issue (by using posix_memalign on the buffer used on
p{read,write} call) and by refactoring it common files to avoid
the need check on defines to correct set the alias and internal
symbols.
Checked on microblaze-linux-gnu check with run-built-tests=no and
by using the sysdeps/posix implementation on x86_64-linux-gnu (just
for sanity test where it shown no regression).

Suppress internal declarations for most of the testsuite.
This patch adds a new build module called 'testsuite'.
IS_IN (testsuite) implies _ISOMAC, as do IS_IN_build and __cplusplus
(which means several ad-hoc tests for __cplusplus can go away).
libc-symbols.h now suppresses almost all of *itself* when _ISOMAC is
defined; in particular, _ISOMAC mode does not get config.h
automatically anymore.
There are still quite a few tests that need to see internal gunk of
one variety or another. For them, we now have 'tests-internal' and
'test-internal-extras'; files in this category will still be compiled
with MODULE_NAME=nonlib, and everything proceeds as it always has.
The bulk of this patch is moving tests from 'tests' to
'tests-internal'. There is also 'tests-static-internal', which has
the same effect on files in 'tests-static', and 'modules-names-tests',
which has the *inverse* effect on files in 'modules-names' (it's
inverted because most of the things in modules-names are *not* tests).
For both of these, the file must appear in *both* the new variable and
the old one.
There is also now a special case for when libc-symbols.h is included
without MODULE_NAME being defined at all. (This happens during the
creation of libc-modules.h, and also when preprocessing Versions
files.) When this happens, IS_IN is set to be always false and
_ISOMAC is *not* defined, which was the status quo, but now it's
explicit.
The remaining changes to C source files in this patch seemed likely to
cause problems in the absence of the main change. They should be
relatively self-explanatory. In a few cases I duplicated a definition
from an internal header rather than move the test to tests-internal;
this was a judgement call each time and I'm happy to change those
however reviewers feel is more appropriate.
* Makerules: New subdir configuration variables 'tests-internal'
and 'test-internal-extras'. Test files in these categories will
still be compiled with MODULE_NAME=nonlib. Test files in the
existing categories (tests, xtests, test-srcs, test-extras) are
now compiled with MODULE_NAME=testsuite.
New subdir configuration variable 'modules-names-tests'. Files
which are in both 'modules-names' and 'modules-names-tests' will
be compiled with MODULE_NAME=testsuite instead of
MODULE_NAME=extramodules.
(gen-as-const-headers): Move to tests-internal.
(do-tests-clean, common-mostlyclean): Support tests-internal.
* Makeconfig (built-modules): Add testsuite.
* Makefile: Change libof-check-installed-headers-c and
libof-check-installed-headers-cxx to 'testsuite'.
* Rules: Likewise. Support tests-internal.
* benchtests/strcoll-inputs/filelist#en_US.UTF-8:
Remove extra-modules.mk.
* config.h.in: Don't check for __OPTIMIZE__ or __FAST_MATH__ here.
* include/libc-symbols.h: Move definitions of _GNU_SOURCE,
PASTE_NAME, PASTE_NAME1, IN_MODULE, IS_IN, and IS_IN_LIB to the
very top of the file and rationalize their order.
If MODULE_NAME is not defined at all, define IS_IN to always be
false, and don't define _ISOMAC.
If any of IS_IN (testsuite), IS_IN_build, or __cplusplus are
true, define _ISOMAC and suppress everything else in this file,
starting with the inclusion of config.h.
Do check for inappropriate definitions of __OPTIMIZE__ and
__FAST_MATH__ here, but only if _ISOMAC is not defined.
Correct some out-of-date commentary.
* include/math.h: If _ISOMAC is defined, undefine NO_LONG_DOUBLE
and _Mlong_double_ before including math.h.
* include/string.h: If _ISOMAC is defined, don't expose
_STRING_ARCH_unaligned. Move a comment to a more appropriate
location.
* include/errno.h, include/stdio.h, include/stdlib.h, include/string.h

Consolidate Linux read syscall
This patch consolidates the read Linux syscall implementation on
sysdeps/unix/sysv/linux/read.c. This leads to a different frame
pointer creation on some architectures:
* It fixes BZ#21428 on aarch64, since now the returned address
for the read syscall can be correctly found out by
backtrace_symbols.
* It makes tst-backtrace{5,6} fails on powerpc due an issue on
its custom backtrace implementation. It is fixed on subsequent
patch from this set.

Condition some sys/ucontext.h contents on __USE_MISC (bug 21457).
Continuing the fixes for namespace issues arising from sys/ucontext.h, this patch conditions various definitions, that are not needed for defining mcontext_t / ucontext_t, on __USE_MISC, so they do not appear in strict POSIX modes. This patch is non-exhaustive; that is, it only conditions straightforward cases and there may be more such definitions that can be conditioned for these and other architectures, to be dealt with later in separate patches. Also, using __USE_MISC is the minimum change for these definitions where they conflict with POSIX; some headers already have __USE_GNU conditionals on similar definitions of names for registers. The patch specifically does not do anything with definitions in bits/sigcontext.h, and nor does it condition any inclusions of bits/sigcontext.h even where in fact that is not needed on some architectures for the definitions of mcontext_t / ucontext_t. As other namespace issues in these headers remain, this patch does not fix bug 21457, nor allow any XFAILs to be removed. Tested with build-many-glibcs.py.

Remove MIPS32 accept4, recvmmsg, sendmmsg implementations.
MIPS32 has its own implementations of accept4, recvmmsg and sendmmsg because at one point it needed to avoid socketcall being used for those functions (MIPS32 has socketcall, but has never used it in glibc, and so never had socket.S at the time when socketcall used such a per-architecture file instead of C code). The current code no longer uses socketcall based on __NR_socketcall being defined, and the syscalls are always present on MIPS for supported kernels so the socketcall case in the code is dead for MIPS; this patch removes the implementations that are, as Adhemerval noted, no longer needed. Tested compilation for mips-linux-gnu with build-many-glibcs.py. * sysdeps/unix/sysv/linux/mips/mips32/accept4.c: Remove file. * sysdeps/unix/sysv/linux/mips/mips32/recvmmsg.c: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/sendmmsg.c: Likewise. |

Simplify accept4, recvmmsg, sendmmsg code.
The accept4, recvmmsg and sendmmsg functions had macros __ASSUME_*_SYSCALL_WITH_SOCKETCALL. Before we could assume kernels with the relevant functionality, these macros represented the conditions under which, on a socketcall architecture, glibc could just call the syscall unconditionally and not have to deal with socketcall at all for those functions, because if the syscall didn't work for them the socketcall call wouldn't either. Now we can assume kernels with the relevant functionality, the only question is whether we can assume the syscall is present; if not, we are on a socketcall architecture and just use socketcall instead. Thus, this patch removes the macros that are no longer necessary, and simplifies the code for accept4, recvmmsg and sendmmsg to use the same logic as the other C implementations of socket functions that may use a syscall or socketcall depending on kernel support. Tested for x86_64 and x86. * sysdeps/unix/sysv/linux/accept4.c (accept4): Use syscall if [__ASSUME_ACCEPT4_SYSCALL], otherwise socketcall. * sysdeps/unix/sysv/linux/recvmmsg.c (recvmmsg): Use syscall if [__ASSUME_RECVMMSG_SYSCALL], otherwise socketcall. * sysdeps/unix/sysv/linux/sendmmsg.c (__sendmmsg): Use syscall if [__ASSUME_SENDMMSG_SYSCALL], otherwise socketcall. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_ACCEPT4_SYSCALL): Move to general list of macros for socket syscalls.

Simplify sendmmsg code.

Simplify recvmmsg code.
Now we can assume a kernel with recvmmsg support, this patch simplifies the implementation to be similar to that for accept4: either using socketcall or the syscall according to whether the syscall is known to be available, without further fallback implementations. (In fact further simplification is possible, getting rid of the __ASSUME_*_SYSCALL_WITH_SOCKETCALL macros now that the minimum kernel is guaranteed support for all of accept4, recvmmsg, sendmmsg, whether through syscalls or through socketcall. I intend to do that for all of accept4 / recvmmsg / sendmmsg together - so making their implementations just like those for older socket functions - once the basic cleanup for 3.2 minimum kernel is done for sendmmsg as well as recvmmsg.) Tested for x86_64 and x86. * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_RECVMMSG_SYSCALL): Define unconditionally. (__ASSUME_RECVMMSG_SOCKETCALL): Remove macro.

Assume prlimit64 is available.
This patch makes sysdeps/unix/sysv/linux code assume the prlimit64 syscall is always available, given the minimum of a 3.2 kernel. __ASSUME_PRLIMIT64, which in fact was no longer used, is removed.

Require Linux kernel 3.2 or later on x86 / x86_64.
As per the recent discussion, this patch implements a requirement for Linux 3.2 or later for x86 and x86_64. This is only the initial change to increase the configured minimum; it's expected that followup patches would deal with associated removal of conditionals that are no longer needed. If we remove the start-up test on the kernel version, of course the NEWS and README text should then be revised (to reflect that this version is just one such that glibc does not intend to include compatibility code for any older kernel version, rather than older kernels necessarily failing to work or glibc necessarily having compatibility code for newer interfaces). The followups would be able to assume presence of getcpu (x86_64), recvmmsg (not always through its own syscall, sometimes only through socketcall), sendmmsg (likewise), /proc/$pid/task/$tid/comm, f_flags from statfs, prlimit64.

Use __glibc_reserved convention in mcontext, sigcontext (bug 21457).
This patch implements the most straightforward part of fixing namespace issues for sys/ucontext.h and related headers: where fields in sys/ucontext.h or bits/sigcontext.h are named "reserved", "padding" or similar, they are renamed to use the __glibc_reserved* naming convention. It does not change fields with a leading underscore, or even those with a prefix such as uc_ or sc_. It only fixes a small part of bug 21457, so no XFAILs are removed. Tested for x86_64 and x86, and with build-many-glibcs.py. [BZ #21457] * sysdeps/unix/sysv/linux/mips/sys/ucontext.h [_MIPS_SIM != _ABIO32] (mcontext_t): Rename field reserved to __glibc_reserved1. * sysdeps/unix/sysv/linux/x86/bits/sigcontext.h (struct _fpx_sw_bytes): Rename field padding to __glibc_reserved1.

x86: Set dl_platform and dl_hwcap from CPU features [BZ #21391]
dl_platform and dl_hwcap are set from AT_PLATFORM and AT_HWCAP very early during startup. They are used by dynamic linker to determine platform and build an array of hardware capability names, which are added to search path when loading shared object. dl_platform and dl_hwcap are unused on x86-64. On i386, i386, i486, i586 and i686 platforms were supported and only SSE2 capability was used. On x86, usage of AT_PLATFORM and AT_HWCAP to determine platform and processor capabilities is obsolete since all information is available in dl_x86_cpu_features. This patch sets dl_platform and dl_hwcap from dl_x86_cpu_features in dynamic linker. On i386, the available plaforms are changed to i586 and i686 since i386 has been deprecated. On x86-64, the available plaforms are haswell, which is for Haswell class processors with BMI1, BMI2, LZCNT, MOVBE, POPCNT, AVX2 and FMA, and xeon_phi, which is for Xeon Phi class processors with AVX512F, AVX512CD, AVX512ER and AVX512PF. A capability, avx512_1, is also added to x86-64 for AVX512 ISAs: AVX512F, AVX512CD, AVX512BW, AVX512DQ and AVX512VL.

Consolidate Linux select implementation
This patch consolidates the select Linux syscall implementation on
sysdeps/unix/sysv/linux/select.c. The changes are:
1. Remove select from auto-generation syscalls.list on the architecture
that uses __NR_select.
2. Remove generic implementation add a default one that handle all
current cases (with the expection of alpha)
The new default implementation will either use __NR_select if
available of fallback to __NR_pselect6 otherwise.
3. Add a alpha outlier implementation which requires old compatibility
symbols.

Fix sys/socket.h namespace issues from sys/uio.h inclusion (bug 21426).
sys/socket.h includes sys/uio.h to get the definition of the iovec
structure.
POSIX allows sys/socket.h to make all sys/uio.h symbols visible.
However, all of sys/uio.h is XSI-shaded, so for non-XSI POSIX this
results in conformtest failures (for sys/socket.h and other headers
that include it):
Namespace violation: "UIO_MAXIOV"
Namespace violation: "readv"
Namespace violation: "writev"
Now, there is some ambiguity in POSIX about what namespace
reservations apply in this case - see
http://austingroupbugs.net/view.php?id=1127 - but glibc convention
would still avoid declaring readv and writev, for example, for feature
test macros that don't include them (if only headers from the relevant
standard are included), even if such declarations are permitted, so
there is a bug here according to glibc conventions.
This patch moves the struct iovec definition to a new
bits/types/struct_iovec.h header and includes that from sys/socket.h
instead of including the whole of sys/uio.h. This fixes the namespace
issue; however, three files in glibc that were relying on the implicit
inclusion needed to be updated to include sys/uio.h explicitly. So
there is a question of whether sys/socket.h should continue to include
sys/uio.h under some conditions, such as __USE_XOPEN or __USE_MISC or
__USE_XOPEN || __USE_MISC, for greater compatibility with code that
(wrongly) expects this optional inclusion to be present there. (I
think the three affected files in glibc should still have explicit
sys/uio.h inclusions added in any case, however.)
Tested for x86_64.

* misc/bits/types/struct_iovec.h: New file.
* misc/Makefile (headers): Add bits/types/struct_iovec.h.

Fix bits/socket.h IOC* namespace issues (bug 21267).
sysdeps/unix/sysv/linux/bits/socket.h includes asm/socket.h. That includes asm/sockios.h, which on MIPS includes asm/ioctl.h, resulting in namespace violations from IOC* macros. bits/socket.h already has code to handle asm/socket.h unconditionally defining macros that are only wanted for __USE_MISC. This patch extends it to handle the IOC* macros as well (always undefining them if not defined when bits/socket.h was included, as I don't think they are part of the intended API even for __USE_MISC). It's possible there should also be a kernel fix - it's not clear to me that IOC* belong in the uapi headers, and even if they do they might best be split out into another header to avoid getting defined by this particular path. But since glibc needs to deal with existing kernel headers, it also seems appropriate to extend the existing workaround to these macros. Tested (compilation only) with build-many-glibcs.py. [BZ #21267] * sysdeps/unix/sysv/linux/bits/socket.h (IOCSIZE_MASK): Undefine if defined by <asm/socket.h> and not previously defined. (IOCSIZE_SHIFT): Likewise. (IOC_IN): Likewise.

Consolidate Linux mmap implementation (BZ#21270)
This patch consolidates all Linux mmap implementations on default
sysdeps/unix/sysv/linux/mmap{64}.c one. To accomodate all required
architecture specific requeriments a new internal header is created
(mmap_internal.h) where each architecture add its specific code
requirements. Currently only x86_64 (to define MMAP_PREPARE to add
MAP_32BITS), s390 (which have a different kernel ABI for mmap), m68k
(which have variable minimum page sizes), and MIPS n32 (which zero
extend the offset to handle negative one correctly) redefine the new
header.
The patch also fixes BZ#21270 where default mmap64 on architectures
which uses mmap2 silent truncates large offsets value (larger than
1 << (page shift + 8 * sizeof (off_t)) or 1<<44 on architectures with
4096 bytes page size). The new consolidate implementation returns
EINVAL as allowed by POSIX.
It also adds a tests for on current tst-mmap-offset one. I have run
a full make check on x86_64, x86_64-32, i686, aarch64, armhf, powerpc,
powerpc64le, sparc64, and sparcv9 without any regressions. I also ran
some basic tests (tst-mmap-offset) on sh4, m68k, and on qemu simulated

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:

posix_spawn: use a larger min stack for -fstack-check [BZ #21253]
When glibc is built with -fstack-check, trying to use posix_spawn can
lead to segfaults due to gcc internally probing stack memory too far.
The new spawn API will allocate a minimum of 1 page, but the stack
checking logic might probe a couple of pages. When it tries to walk
them, everything falls apart.
The gcc internal docs [1] state the default interval checking is one
page. Which means we need two pages (the current one, and the next
probed). No target currently defines it larger.
Further, it mentions that the default minimum stack size needed to
recover from an overflow is 4/8KiB for sjlj or 8/12KiB for others.
But some Linux targets (like mips and ppc) go up to 16KiB (and some
non-Linux targets go up to 24KiB).
Let's create each child with a minimum of 32KiB slack space to support
them all, and give us future breathing room.
No test is added as existing ones crash. Even a simple call is
enough to trigger the problem:
char *argv[] = { "/bin/ls", NULL };
posix_spawn(NULL, "/bin/ls", NULL, NULL, argv, NULL);

Fix more test-errno issues
This patch fixes some test-errno-linux unexpected returns for the
tested syscalls on some older kernels (I saw it on a Linux 3.8 on
armv7l). Basically:
- inotify_add_watch: Linux v3.8 (676a0675c) removed the test to
check at least one valid bit in flags (to return EINVAL). It
was later added back in v3.9 (04df32fa1).
- quotactl: returns ENOSYS for kernels not configured with
CONFIG_QUOTA.
Checked on x86_64-linux-gnu and armv7l-linux-gnueabihf.
* sysdeps/unix/sysv/linux/test-errno-linux.c (do_test): Handle
non expected inotify_add_watch and quotactl return.

Consolidate set* Linux implementation
This patch consolidates the Linux setegid, seteuid, setgid, setgroups, setregid, setresgid, setresuid, setreuid, and setuid implementation on default sysdeps/unix/sysv/linux/set*.c implementation. It basically removes all the architecture define implementations and add support for __NR_set*32 syscall on Linux default implementation. Checked on i686-linux-gnu, x86_64-linux-gnu, x86_64-linux-gnux32, aarch64-linux-gnu, arm-linux-gnueabihf, and powerpc64le-linux-gnu. * sysdeps/unix/sysv/linux/arm/setegid.c: Remove file. * sysdeps/unix/sysv/linux/arm/seteuid.c: Likewise. * sysdeps/unix/sysv/linux/arm/setgid.c: Likewise. * sysdeps/unix/sysv/linux/arm/setgroups.c: Likewise. * sysdeps/unix/sysv/linux/arm/setregid.c: Likewise. * sysdeps/unix/sysv/linux/arm/setresgid.c: Likewise. * sysdeps/unix/sysv/linux/arm/setresuid.c: Likewise. * sysdeps/unix/sysv/linux/arm/setreuid.c: Likewise. * sysdeps/unix/sysv/linux/arm/setuid.c: Likewise. * sysdeps/unix/sysv/linux/i386/setegid.c: Likewise. * sysdeps/unix/sysv/linux/i386/seteuid.c: Likewise. * sysdeps/unix/sysv/linux/i386/setgid.c: Likewise. * sysdeps/unix/sysv/linux/i386/setgroups.c: Likewise. * sysdeps/unix/sysv/linux/i386/setregid.c: Likewise. * sysdeps/unix/sysv/linux/i386/setresgid.c: Likewise. * sysdeps/unix/sysv/linux/i386/setresuid.c: Likewise. * sysdeps/unix/sysv/linux/i386/setreuid.c: Likewise. * sysdeps/unix/sysv/linux/i386/setuid.c: Likewise. * sysdeps/unix/sysv/linux/m68k/setegid.c: Likewise. * sysdeps/unix/sysv/linux/m68k/seteuid.c: Likewise. * sysdeps/unix/sysv/linux/m68k/setgid.c: Likewise. * sysdeps/unix/sysv/linux/m68k/setgroups.c: Likewise. * sysdeps/unix/sysv/linux/m68k/setregid.c: Likewise. * sysdeps/unix/sysv/linux/m68k/setresgid.c: Likewise. * sysdeps/unix/sysv/linux/m68k/setresuid.c: Likewise. * sysdeps/unix/sysv/linux/m68k/setreuid.c: Likewise. * sysdeps/unix/sysv/linux/m68k/setuid.c: Likewise. * sysdeps/unix/sysv/linux/microblaze/setgroups.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/setegid.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/seteuid.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/setgid.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/setgroups.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/setregid.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/setresgid.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/setresuid.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/setreuid.c: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/setuid.c: Likewise. * sysdeps/unix/sysv/linux/sh/setegid.c: Likewise. * sysdeps/unix/sysv/linux/sh/seteuid.c: Likewise. * sysdeps/unix/sysv/linux/sh/setgid.c: Likewise. * sysdeps/unix/sysv/linux/sh/setgroups.c: Likewise. * sysdeps/unix/sysv/linux/sh/setregid.c: Likewise. * sysdeps/unix/sysv/linux/sh/setresgid.c: Likewise. * sysdeps/unix/sysv/linux/sh/setresuid.c: Likewise. * sysdeps/unix/sysv/linux/sh/setreuid.c: Likewise. * sysdeps/unix/sysv/linux/sh/setuid.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/setegid.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/seteuid.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/setgid.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/setgroups.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/setregid.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/setresgid.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/setresuid.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/setreuid.c: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/setuid.c: Likewise. * sysdeps/unix/sysv/linux/setegid.c (setegid): Use INLINE_SYSCALL_ERROR_RETURN_VALUE. * sysdeps/unix/sysv/linux/seteuid.c (seteuid): Likewise. * sysdeps/unix/sysv/linux/setgid.c (setgid): Use __NR_setgid32 if defined. * sysdeps/unix/sysv/linux/setgroups.c (setgroups): Use __NR_setgroups32 if defined. * sysdeps/unix/sysv/linux/setregid.c (__setregid): Use __NR_setregid32 if defined. * sysdeps/unix/sysv/linux/setresgid.c (__setresgid): Use __NR_setresgid32 is defined. * sysdeps/unix/sysv/linux/setresuid.c (__setresuid): Use __NR_setresuid32 if defined. * sysdeps/unix/sysv/linux/setreuid.c (__setreuid): Use __NR_setreuid32 if defined. * sysdeps/unix/sysv/linux/setuid.c (__setuid): Use __NR_setuid32 if defined. |

Define more termios.h macros unconditionally for alpha (bug 21277).
termios.h should define IUCLC for UNIX98 and older XSI standards. The sysdeps/unix/sysv/linux/alpha version defines it only if __USE_MISC, so causing some conform/ tests to fail. Other versions define it unconditionally (I* being a reserved namespace for this header); the API should be consistent between architectures in the absence of a clear reason for it to differ (and given that a symbol is part of the API on two architectures, I don't see any reason for the feature test macros required ever to differ between those architectures), so this patch makes the alpha version define it unconditionally as well. Two non-POSIX macros alongside it, IMAXBEL and IUTF8, are also defined unconditionally on other architectures, so this patch makes them consistent by defining them unconditionally on alpha as well. Tested (compilation only) with build-many-glibcs.py. [BZ #21277] * sysdeps/unix/sysv/linux/alpha/bits/termios.h (IUCLC): Define unconditionally. (IMAXBEL): Likewise. (IUTF8): Likewise. |

conformtest: Add x32 XFAILs for mq_attr element types (bug 21279).
POSIX specifies long as the type of elements of struct mq_attr. For x32, they are __syscall_slong_t (i.e. long long). This patch XFAILs the corresponding tests for x32 in the conformtest expectations (the bug should not be closed without an actual fix). Tested with build-many-glibcs.py. [BZ #21279] * sysdeps/unix/sysv/linux/x86_64/x32/Makefile [$(subdir) = conform] (conformtest-xfail-conds): Update comment. * conform/data/mqueue.h-data (mq_attr.mq_flags): XFAIL for x86_64-x32-linux. (mq_attr.mq_maxmsg): Likewise. (mq_attr.mq_msgsize): Likewise. (mq_attr.mq_curmsgs): Likewise. |

conformtest: Add mips XFAIL for struct stat st_rdev type (bug 21278).
MIPS o32 struct stat has the wrong type of st_rdev. This patch XFAILs that test in the conformtest expectations for this case (the bug should not be closed without an actual fix, however). Tested with build-many-glibcs.py. [BZ #21278] * sysdeps/unix/sysv/linux/mips/mips32/Makefile [$(subdir) = conform] (conformtest-xfail-conds): Update comment. * conform/data/sys/stat.h-data (stat.st_rdev): XFAIL for mips-o32-linux. |

Fix alpha termios.h NL2, NL3 namespace (bug 21268).
sysdeps/unix/sysv/linux/alpha/bits/termios.h defines NL2 and NL3 for __USE_MISC || __USE_XOPEN. These should only be defined for __USE_MISC as they are not part of any standard namespace. This patch conditions them accordingly, matching the powerpc version of the header (the only other one in glibc that defines these macros). Tested (compilation only) with build-many-glibcs.py. [BZ #21268] * sysdeps/unix/sysv/linux/alpha/bits/termios.h (NL2): Define only if [__USE_MISC] (NL3): Likewise. |
