* Use C11-like atomics instead of plain memory accesses in x86 lock elision.Torvald Riegel2016-12-052-15/+31
| | | | | | | | | | | | | | | | | This uses atomic operations to access lock elision metadata that is accessed concurrently (ie, adapt_count fields). The size of the data is less than a word but accessed only with atomic loads and stores; therefore, we add support for shorter-size atomic load and stores too. * include/atomic.h (__atomic_check_size_ls): New. (atomic_load_relaxed, atomic_load_acquire, atomic_store_relaxed, atomic_store_release): Use it. * sysdeps/x86/elide.h (ACCESS_ONCE): Remove. (elision_adapt, ELIDE_LOCK): Use atomics. * sysdeps/unix/sysv/linux/x86/elision-lock.c (__lll_lock_elision): Use atomics and improve code comments. * sysdeps/unix/sysv/linux/x86/elision-trylock.c (__lll_trylock_elision): Likewise.
* Consolidate Linux setrlimit and getrlimit implementationAdhemerval Zanella2016-11-171-0/+5

It contains two exceptions: 1. mips32 and mips64n32 which requires a versioned symbol for GLIBC 2.19 and higher due a broken RLIM64_INFINITY constant. 2. sparc32 does not define a compat symbol for getrlimit64 for old 2GB limit. I am not sure if it is required, but a RLIM_INFINITY fix [1] change its definition without adding a compat symbol. This patch does not aim to address this possible issue, it follow current symbol export. The default implementation uses prlimit64 for 64 bit rlim_t ({set,get}rlimit64) and if it fails with ENOSYS it fall back to {get,set}rlimit syscall. This code path is only used on kernel older than 2.6.36 (basically now only x86) and I avoid to user __ASSUME_PRLIMTI64 to simplify the implementation. Once x86 moves to be on par with other architectures regarding minimum kernel supported we can get rid of using old syscalls and default path. A new type size define is added, __RLIM_T_MATCHES_RLIM64_T, where is set as default for 64 bits ports. This allows the default implementation to avoid {get,set}rlimit building and alias {get,set}rlimit64 to {get,set}rlimit. Checked on x86_64, i386, armhf, aarch64, and powerpc64le. I also did a sanity build plus check-abi on all other supported architectures.

* i386, x86: Use libc_ifunc macro for time, gettimeofday.Stefan Liebler2016-10-072-27/+27
| | | | | | | | | | | | | | | | | | | | | | | This patch uses the libc_ifunc_hidden macro to create already existing ifunc functions time and gettimeofday on intel. This way, the libc_hidden_def macro can be used instead of the libc_ifunc_hidden_def one which was only used here. Thus the macro is removed from libc-symbols.h. On i386, the __GI_* symbols do not target the ifunc symbol and thus the redirection construct has to be applied here. ChangeLog: * sysdeps/unix/sysv/linux/x86/gettimeofday.c (__gettimeofday): Use libc_ifunc_hidden macro. Use libc_hidden_def instead of libc_ifunc_hidden_def. * sysdeps/unix/sysv/linux/x86/time.c (time): Likewise. * sysdeps/unix/sysv/linux/i386/gettimeofday.c (__gettimeofday): Redirect ifunced function in header for using it as type of ifunc'ed function.

* Installed-header hygiene (BZ#20366): stack_t.Zack Weinberg2016-09-231-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sys/ucontext.h unconditionally uses stack_t, and it does not make sense to change that. But signal.h only declares stack_t under __USE_XOPEN_EXTENDED || __USE_XOPEN2K8. The actual definition is already in a bits header, bits/sigstack.h, but that header insists on only being included by signal.h, so we have to change that as well as all of the sys/ucontext.h variants. (Some but not all variants of bits/sigcontext.h, which sys/ucontext.h may also need, had already received this adjustment; for consistency, I made them all the same, even if that's not strictly necessary in some configurations.) bits/sigcontext.h and bits/sigstack.h also all need to receive multiple inclusion guards. * sysdeps/generic/sys/ucontext.h * sysdeps/arm/sys/ucontext.h * sysdeps/i386/sys/ucontext.h * sysdeps/m68k/sys/ucontext.h * sysdeps/mips/sys/ucontext.h * sysdeps/unix/sysv/linux/aarch64/sys/ucontext.h * sysdeps/unix/sysv/linux/alpha/sys/ucontext.h * sysdeps/unix/sysv/linux/arm/sys/ucontext.h * sysdeps/unix/sysv/linux/hppa/sys/ucontext.h * sysdeps/unix/sysv/linux/ia64/sys/ucontext.h * sysdeps/unix/sysv/linux/m68k/sys/ucontext.h * sysdeps/unix/sysv/linux/mips/sys/ucontext.h * sysdeps/unix/sysv/linux/nios2/sys/ucontext.h * sysdeps/unix/sysv/linux/powerpc/sys/ucontext.h * sysdeps/unix/sysv/linux/s390/sys/ucontext.h * sysdeps/unix/sysv/linux/sh/sys/ucontext.h * sysdeps/unix/sysv/linux/sparc/sys/ucontext.h * sysdeps/unix/sysv/linux/tile/sys/ucontext.h * sysdeps/unix/sysv/linux/x86/sys/ucontext.h: Include both bits/sigcontext.h and bits/sigstack.h.

* x86: Remove vsyscall usageAdhemerval Zanella2015-06-092-3/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the vsyscall usage for x86_64 port. As indicated by kernel code comments [1], vsyscalls are a legacy ABI and its concept is problematic: - It interferes with ASLR. - It's awkward to write code that lives in kernel addresses but is callable by userspace at fixed addresses. - The whole concept is impossible for 32-bit compat userspace. - UML cannot easily virtualize a vsyscall. The VDSO is a better approach for such functionality.

| | | | | | | | This patch consolidates the sched_getcpu implementations across all arches (except tile, which requires its own). This patch removes the powerpc, x86_64 and x32 specific files and change the default linux one to use INLINE_VSYSCALL where possible (for ports that implements it).

* Consolidate vDSO macros and usageAdhemerval Zanella2015-05-261-1/+3
| | | | | | | | | | | | | | | | This patch consolidate the Linux vDSO define and usage across all ports that uses it. The common vDSO definitions and calling through {INLINE/INTERNAL}_VSYSCALL macros are moved to a common header sysdep-vdso.h and vDSO name declaration and prototype is defined using a common macro. Also PTR_{MANGLE,DEMANGLE} is added to ports that does not use them for vDSO calls (aarch64, powerpc, s390, and tile) and thus it will reflect in code changes. For ports that already implement pointer mangling/demangling in vDSO system (i386, x32, x86_64) this patch is mainly a code refactor. Checked on x32, x86_64, x32, ppc64le, and aarch64.

* Add x86 32 bit vDSO time function supportAdhemerval Zanella2015-01-126-0/+201
| | | | | | | | | | Linux 3.15 adds support for clock_gettime, gettimeofday, and time vDSO (commit id 37c975545ec63320789962bf307f000f08fabd48). This patch adds GLIBC supports to use such symbol when they are avaiable. Along with x86 vDSO support, this patch cleanup x86_64 code by moving all common code to x86 common folder. Only init-first.c is different between implementations.

So that gnu/lib-names.h supports multiple ABIs, it is changed to be generated on the same basis as gnu/stubs.h: when there are multiple ABIs, gnu/lib-names.h is a wrapper header (the same header installed whatever ABI is being built) and separate headers such as gnu/lib-names-64.h contain the substantive contents (only one such header being installed by any glibc build). The rules for building gnu/lib-names.h were moved from Makeconfig to Makerules because they need to come after sysdeps makefiles are included (now that "ifndef abi-variants" is a toplevel conditional on the rules rather than $(abi-variants) being evaluated later inside the commands for a rule). Tested for x86_64 and x86 that the installed shared libraries are unchanged by this patch, and examined the installed gnu/lib-names*.h headers by hand. Also tested the case of a single ABI (where there is just a single header installed, again like stubs.h) by hacking abi-variants to empty for x86_64. [BZ #14171] * Makeconfig [$(build-shared) = yes] ($(common-objpfx)soversions.mk): Don't handle SONAMEs specified in makefiles.

* Add adaptive elision to rwlocksAndi Kleen2014-06-131-0/+2
| | | | | | | | | | | | | | | | | | | This patch relies on the C version of the rwlocks posted earlier. With C rwlocks it is very straight forward to do adaptive elision using TSX. It is based on the infrastructure added earlier for mutexes, but uses its own elision macros. The macros are fairly general purpose and could be used for other elision purposes too. This version is much cleaner than the earlier assembler based version, and in particular implements adaptation which makes it safer. I changed the behavior slightly to not require any changes in the test suite and fully conform to all expected behaviors (generally at the cost of not eliding in various situations). In particular this means the timedlock variants are not elided. Nested trylock aborts.
