* ARM: Remove lowlevellock.cWill Newton2014-05-011-132/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lowlevellock.c for arm differs from the generic lowlevellock.c only in insignificant ways, so can be removed. Happily, this fixes BZ 15119 (unnecessary busy loop in __lll_timedlock_wait on arm). The notable differences between the arm and generic implementations are: 1) arm __lll_timedlock_wait has a fast path out if futex has been set to 0 between since the function was called. This seems unlikely to happen very often, so it seems at worst harmless to lose this fast path. 2) Some function in arm's lowlevellock.c set futex to 2 if it was 1. The generic version always sets the futex to 2. As futex can only be 0, 1 or 2 on entry into these functions, the behaviour is equivalent. (If the futex manages to be 0 on entry then we've just lost another unlikely fast path out.) There are no test suite regressions. Note that hppa and sparc also have their own lowlevellock.c. I believe hppa can also be removed, so I'll send a separate patch for that shortly. sparc's seems to be genuinely needed as it uses a different locking structure. Also note that the analysis at https://sourceware.org/ml/libc-ports/2013-02/msg00021.html indicates a further locking performance bug to fix - I've got a partial patch for that which I can submit once I've finished testing. 2014-05-01 Bernard Ogden <bernie.ogden@linaro.org> [BZ #15119] * sysdeps/unix/sysv/linux/arm/nptl/lowlevellock.c: Remove file.

* Increase minimum Linux kernel version to 2.6.32.Joseph Myers2014-04-306-42/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch increases the minimum Linux kernel version for glibc to 2.6.32, as discussed in the thread starting at <https://sourceware.org/ml/libc-alpha/2014-01/msg00511.html>. This patch just does the minimal change to arch_minimum_kernel settings (and LIBC_LINUX_VERSION, which determines the minimum kernel headers version, as it doesn't make sense for that to be older than the minimum kernel that can be used at runtime). Followups would be expected to do, roughly and not necessarily precisely in this order: * Remove __LINUX_KERNEL_VERSION checks in kernel-features.h files where those checks are always true / always false for kernels 2.6.32 and above. * Otherwise simplify/improve conditionals in those files (for example, where defining once in the main file then undefining in architecture-specific files makes things clearer than having lots of separate definitions of the same macro), possibly fixing in the process cases where a macro should optimally have been defined for a given architecture but wasn't. (In the review in preparation for this version increase I checked what the right conditions should be for all macros in the main kernel-features.h whose definitions there would have been affected by the increase - but I only fixed that subset of the issues found where --enable-kernel=2.6.32 would have caused a kernel feature to be wrongly assumed to be present, not any cases where a feature is not assumed but could be assumed.) * Remove conditionals on __ASSUME_* where they can now be taken to be always-true, and the definitions when the macros are only used in Linux-specific files. * Split more architectures out of the main kernel-features.h (like ex-ports architectures), once various of the architecture conditionals there have been eliminated so the new architecture-specific files are no larger than actually necessary. Tested x86_64. 2014-03-27 Joseph Myers <joseph@codesourcery.com> [BZ #9894] * sysdeps/unix/sysv/linux/configure.ac (LIBC_LINUX_VERSION): Change to 2.6.32.

* aarch64: Re-implement setcontext without rt_sigreturn syscallWill Newton2014-04-171-55/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation of setcontext uses rt_sigreturn to restore the contents of registers. This contrasts with the way most other architectures implement setcontext: powerpc64, mips, tile: Call rt_sigreturn if context was created by a call to a signal handler, otherwise restore in user code. powerpc32: Call swapcontext system call and don't call sigreturn or rt_sigreturn. x86_64, sparc, hppa, sh, ia64, m68k, s390, arm: Only support restoring "synchronous" contexts, that is contexts created by getcontext, and restoring in user code and don't call sigreturn or rt_sigreturn. alpha: Call sigreturn (but not rt_sigreturn) in all cases to do the restore. The text of the setcontext manpage suggests that the requirement to be able to restore a signal handler created context has been dropped from SUSv2: If the context was obtained by a call to a signal handler, then old standard text says that "program execution continues with the program instruction following the instruction interrupted by the signal". However, this sentence was removed in SUSv2, and the present verdict is "the result is unspecified". Implementing setcontext by calling rt_sigreturn unconditionally causes problems when used with sigaltstack as in BZ #16629. On this basis it seems that aarch64 is broken and that new ports should only support restoring contexts created with getcontext and do not need to call rt_sigreturn at all. This patch re-implements the aarch64 setcontext function to restore the context in user code in a similar manner to x86_64 and other ports. ChangeLog: 2014-04-17 Will Newton <will.newton@linaro.org> [BZ #16629] * sysdeps/unix/sysv/linux/aarch64/setcontext.S (__setcontext): Re-implement to restore registers in user code and avoid rt_sigreturn system call.

* Move __PTHREAD_SPINS definition to architecture specific headerAdhemerval Zanella2014-04-098-0/+24
| | | | | | | This patch moves the __PTHREAD_SPINS definition to arch specific header since pthread_mutex_t layout is also arch specific. This leads to no need to defining __PTHREAD_MUTEX_HAVE_ELISION and thus removing of the undefined compiler warning.
* PowerPC: define _CALL_ELF if compiler does notAdhemerval Zanella2014-04-062-0/+37
| | | | | | | | | | | | This patch makes the configure adds -D_CALL_ELF=1 when compiler does not define _CALL_ELF (versions before powerpc64le support). It cleans up compiler warnings on old compiler where _CALL_ELF is not defined on powerpc64(be) builds. It does by add a new config.make variable for configure-deduced CPPFLAGS and accumulate into that (confix-extra-cppflags). It also generalizes libc_extra_cflags so it accumulates in sysdeps configure fragmenets.
* Correct robust mutex / PI futex kernel assumptions (bug 9894).Joseph Myers2014-03-315-6/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch continues fixing __ASSUME_* issues in preparation for moving to a 2.6.32 minimum kernel version by addressing assumptions on robust mutex and PI futex support availability. Those assumptions are bug 9894, but to be clear this patch does not address all the issues from that bug about wrong version assumptions, only those still applicable for --enable-kernel=2.6.32 or later (with the expectation that the move to that minimum kernel will obsolete the other parts of the bug). The patch is independent of <https://sourceware.org/ml/libc-alpha/2014-03/msg00585.html>, my other pending-review patch preparing for the kernel version change; the two together complete all the changes I believe are needed in preparation regarding any macro in sysdeps/unix/sysv/linux/kernel-features.h that would be affected by such a change. (I have not checked the correctness of macros whose conditions are unaffected by such a change, or macros only defined in other kernel-features.h files.) As discussed in that bug, robust mutexes and PI futexes need futex_atomic_cmpxchg_inatomic to be implemented, in addition to certain syscalls needed for robust mutexes (and architecture-independent kernel pieces for all the features in question). That is, as I understand it, they need futex_atomic_cmpxchg_inatomic to *work* (not return an ENOSYS error). The issues identified in my analysis relate to ARM, M68K, MicroBlaze, MIPS and SPARC. On ARM, whether futex_atomic_cmpxchg_inatomic works depends on the kernel configuration. As of 3.13, the condition for *not* working is CONFIG_CPU_USE_DOMAINS && CONFIG_SMP. As of 2.6.32 it was simply CONFIG_SMP that meant the feature was not implemented. I don't know if there are any circumstances in which we can say "we can assume a userspace glibc binary built with these options will never run on a kernel with the problematic configuration", but at least for now I'm just undefining the relevant __ASSUME_* macros for ARM. On M68K, two of the three macros are undefined for kernels before 3.10, but as far as I can see __ASSUME_FUTEX_LOCK_PI is in the same group needing futex_atomic_cmpxchg_inatomic support and so should be undefined as well. On MicroBlaze the required support was added in 2.6.33. On MIPS, the support depends on cpu_has_llsc in the kernel - that is, actual hardware LL/SC support (GCC and glibc for MIPS GNU/Linux rely on the instructions being supported in some way, but it may be kernel emulation; futex_atomic_cmpxchg_inatomic doesn't work with that emulation). The same condition as in GCC for indicating LL/SC support may not be available is used for undefining the macros in glibc, __mips == 1 || defined _MIPS_ARCH_R5900. (Maybe we could in fact desupport MIPS processors without the hardware support in glibc.) On SPARC, 32-bit kernels don't support futex_atomic_cmpxchg_inatomic; __arch64__ || __sparc_v9__ is used as the condition for binaries that won't run on 32-bit kernels. This patch is not tested beyond the sanity check of an x86_64 build.

* Fix futimesat for older MicroBlaze kernels (bug 16648).Joseph Myers2014-03-312-0/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the fixes for __ASSUME_* issues in preparation for moving to a 2.6.32 minimum kernel version, this *untested* patch fixes bug 16648, the definition of __ASSUME_ATFCTS meaning that the futimesat syscall is assumed for all MicroBlaze kernels despite not being present until 2.6.33. __ASSUME_ATFCTS controls conditionals relating to a lot of different syscalls in Linux-specific code (fstatat64 faccessat fchmodat fchownat futimesat newfstatat linkat mkdirat openat readlinkat renameat symlinkat unlinkat mknodat), where whether newfstatat fstatat64 futimesat are used depends on the architecture, as well as controlling whether openat64_not_cancel_3 is expected to work in sysdeps/posix/getcwd.c. The assumptions are all OK as of 2.6.32 except for this MicroBlaze case, and it's generally desirable to get rid of as many of the __ASSUME_ATFCTS conditionals as possible, to simplify the code (the fallbacks include potential unbounded dynamic stack allocations). Thus, rather than the simplest approach of undefining __ASSUME_ATFCTS for older kernels on MicroBlaze, this patch takes the approach of using the linux-generic implementation of futimesat for MicroBlaze kernels before 2.6.33 (all such kernels have the utimensat syscall).

* Fix -Wundef warnings for _ABI* on MIPS.Joseph Myers2014-03-212-0/+3
| | | | | | | | | | | | | | | | This patch fixes -Wundef warnings related to the _ABI* macros on MIPS. GCC predefines only the _ABI* macro related to the ABI actually in use, meaning that a conditional such as "#if _MIPS_SIM == _ABI64" is true only for the ABI in question (all the macros are nonzero), but produces a -Wundef warning for the other ABIs. The normal approach to using these macros is to include <sgidefs.h>, which ensures that all three _ABI* macros are defined rather than just one; this patch does so in the places that caused warnings (the bulk of the warnings arising from <bits/wordsize.h>). Tested that the warnings are fixed. * sysdeps/mips/bits/wordsize.h: Include <sgidefs.h>. * sysdeps/unix/sysv/linux/mips/getrlimit64.c: Likewise. * sysdeps/unix/sysv/linux/mips/setrlimit64.c: Likewise.

* Fix __ASSUME_PSELECT for MicroBlaze (bug 16642).Joseph Myers2014-03-121-0/+3
| | | | | | | | | | | | | | | | | | | | Reviewing (for all architectures, with a baseline kernel version of 2.6.32) the kernel support for features for which __ASSUME_* macros would be affected by a move to 2.6.32 as minimum kernel version showed up that __ASSUME_PSELECT was wrongly defined for MicroBlaze, despite the corresponding syscall table entry not being wired up in the MicroBlaze kernel. This patch makes the MicroBlaze kernel-features.h undefine __ASSUME_PSELECT. I'd also encourage wiring it up in the kernel (so you can then make this #undef conditional, and eventually obsolete once a recent-enough kernel is required). I suspect it wasn't wired up because of the mistaken comment in asm/unistd.h "obsolete -> sys_pselect7" (there is no such syscall as pselect7).

| | | | | | | | | | | | | | | | The __ASSUME_UTIMES macro describes whether the utimes syscall is present. For linux-generic architectures, it isn't (utimensat is instead), so the macro should not be defined for them; this patch removes the spurious definitions for such architectures. (Those definitions don't actually cause any user-visible bug, because futimes.c doesn't use __ASSUME_UTIMES if __ASSUME_UTIMENSAT is defined, and futimesat.c and utimes.c are overridden for linux-generic, but the definitions are still logically incorrect.) * sysdeps/unix/sysv/linux/aarch64/kernel-features.h (__ASSUME_UTIMES): Remove. * sysdeps/unix/sysv/linux/tile/kernel-features.h (__ASSUME_UTIMES): Likewise.

* Fix __ASSUME_RECVMMSG issues (bug 16610).Joseph Myers2014-02-2010-6/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to the issues for accept4, __ASSUME_RECVMMSG is also confused about whether it relates to function availability or socketcall operation availability; this is now bug 16610. Nothing actually tests __ASSUME_RECVMMSG for function availability, but implicit in the definition in kernel-features.h is the idea that it makes sense when the syscall is available and socketcall is not being used. As with accept4, there are architectures where the syscall was added later than the socketcall operation, meaning that assuming glibc is built with recent enough kernel headers, it does not attempt to use socketcall for these operations and __ASSUME_RECVMMSG gets defined for kernels >= 2.6.33 even when the syscall was only added later. This patch splits the macro into separate macros like those used for accept4; having similar macro structure in both cases (and for sendmmsg once I've dealt with that) seems likely to be less confusing than having a different structure on the basis of nothing actually needing to assume the recvmmsg function works. Appropriate definitions are added for all architectures. Architecture-specific note: Tile's kernel-features.h says "TILE glibc support starts with 2.6.36", which is accurate in that 2.6.36 was the first kernel version with Tile support, and on that basis I've made that header define __ASSUME_RECVMMSG_SYSCALL unconditionally. However, Tile's configure.ac has arch_minimum_kernel=2.6.32. Since arch_minimum_kernel is meant to reflect only kernel.org kernel versions, I think that should change to 2.6.36. (If using glibc with kernel versions from before a port went in kernel.org, it's your responsibility to change arch_minimum_kernel in a local patch, and at the same time to adjust any __ASSUME_* definitions that may not be correct for your older kernel; for developing the official glibc it should only ever be necessary to consider what official kernel.org releases support.)

* Fix __ASSUME_ACCEPT4 issues (bug 16609).Joseph Myers2014-02-2012-22/+87

As previously noted, __ASSUME_ACCEPT4 is used in two ways: * In OS-independent code, to mean "accept4 can be assumed to work rather than fail with ENOSYS". It doesn't matter whether it's implemented with socketcall or a separate syscall. * In Linux-specific code, to mean "the socketcall multiplex syscall can be assumed to handle the accept4 operation. When used in Linux-specific code, it *never* refers to anything relating to the accept4 syscall, only to the socketcall multiplexer. This patch splits the macro into separate __ASSUME_ACCEPT4_SOCKETCALL, __ASSUME_ACCEPT4_SYSCALL and __ASSUME_ACCEPT4 to clarify the different cases involved. A macro __ASSUME_SOCKETCALL is added for convenience in writing logic relating to all socketcall architectures. In addition, to address the issue of architectures where socketcall support for accept4 was added before a separate syscall was added (and so the separate syscall should not be used unless known to be present or fallback to socketcall is available), a fourth macro __ASSUME_ACCEPT4_SYSCALL_WITH_SOCKETCALL is added to indicate that the syscall became available at the same time as socketcall support. This is then used in the relevant places in a conditional determining whether to undefine __NR_accept4 (the simple approach to avoiding the syscall's presence causing problems; I didn't try to implement runtime fallback from the syscall to socketcall). Architecture-specific note: alpha defined __ASSUME_ACCEPT4 for 2.6.33 and later, but actually the syscall was added for alpha in 3.2, so this patch uses the correct condition for __ASSUME_ACCEPT4_SYSCALL there.

* Combine __USE_BSD and __USE_SVID into __USE_MISC.Joseph Myers2014-02-1212-15/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up following the obsoletion of _BSD_SOURCE and _SVID_SOURCE by combining __USE_BSD and __USE_SVID into __USE_MISC. The only non-mechanical part of this patch is the changes to features.h; everything else is simple substitution of __USE_MISC for the old macros. Thus, this patch leaves obviously redundant conditionals such as "defined __USE_MISC || defined __USE_MISC", and does not update #endif comments where they referred to BSD or SVID in words instead of the literal macro name. This is intended to facilitate patch review by separating the less mechanical changes from these purely mechanical changes into a separate patch. (I do intend to integrate all the changes from <https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I believe includes all the trailing comment updates, in subsequent patches.)

* Relocate AArch64 from ports to libc.Marcus Shawcroft2014-02-1166-0/+6577
| | | | | | | | | | | | | This patch moves the AArch64 port to the main sysdeps hierarchy. The move is essentially: git mv ports/sysdeps/aarch64 sysdeps/aarch64 git mv ports/sysdeps/unix/sysv/linux/aarch64 sysdeps/unix/sysv/linux/aarch64 The README is updated and I've updated ChangeLog.aarch64 along the lines of the ARM move. The AArch64 build has been tested to confirm that there were no changes in objdump -dr output or the shared objects.
* Move mips from ports to libc.Joseph Myers2014-02-10213-0/+22604
| | | | | | | | | | | | | | | | | | | | | | | | | | | | I've moved the MIPS port from ports to the main sysdeps hierarchy. Beyond the README update, the move of the files was simply git mv ports/sysdeps/mips sysdeps/mips git mv ports/sysdeps/unix/mips sysdeps/unix/mips git mv ports/sysdeps/unix/sysv/linux/mips sysdeps/unix/sysv/linux/mips and in addition to the ChangeLog entries here, I put a note at the top of ports/ChangeLog.mips similar to those in other files. Tested that disassembly of installed shared libraries for mips is the same before and after this patch (except for ld.so where paths in assertions are involved, as for arm). * sysdeps/mips: Move directory from ports/sysdeps/mips. * sysdeps/unix/mips: Move directory from ports/sysdeps/unix/mips. * sysdeps/unix/sysv/linux/mips: Move directory from ports/sysdeps/unix/sysv/linux/mips. * README: Update listing for mips-*-linux-gnu and mips64-*-linux-gnu. * sysdeps/mips: Move directory to ../sysdeps/mips. * sysdeps/unix/mips: Move directory to ../sysdeps/unix/mips. * sysdeps/unix/sysv/linux/mips: Move directory to ../sysdeps/unix/sysv/linux/mips.

* Move tilegx, tilepro, and linux-generic from ports to libc.Chris Metcalf2014-02-10184-0/+17050
| | | | | | | | | | | | | | | | I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy, along with the linux-generic ports infrastructure. Beyond the README update, the move was just git mv ports/sysdeps/tile sysdeps/tile git mv ports/sysdeps/unix/sysv/linux/tile \ sysdeps/unix/sysv/linux/tile git mv ports/sysdeps/unix/sysv/linux/generic \ sysdeps/unix/sysv/linux/generic I updated the relevant ChangeLogs along the lines of the ARM move in commit c6bfe5c4d75 and tested the 64-bit tilegx build to confirm that there were no changes in "objdump -dr" output in the shared objects.
