2016-05-04Revert "aio: fix newp->running data race"Samuel Thibault
This reverts commit fd67a9cf7b733da082e4b6a5f25c19ea7921b4cd.
2016-05-04aio: fix newp->running data raceSamuel Thibault
* sysdeps/pthread/aio_misc.c (__aio_enqueue_request): Do not write `running` field of `newp` when a thread was started to process it, since that thread will not take `__aio_requests_mutex`, and the field already has the proper value actually.

2015-06-12Fix aio_* pread namespace (bug 18519).Joseph Myers
aio_* bring in references to pread, which isn't in all the standards containing aio_* (as a reference from one library to another, this is a bug for dynamic as well as static linking). This patch fixes this by using __libc_pread instead, exporting that function from libc at symbol version GLIBC_PRIVATE; the code, with conditionals that may call either __pread64 or __libc_pread, becomes exactly analogous to that elsewhere in the same file that may call either __pwrite64 or __libc_pwrite. Tested for x86_64 and x86 (testsuite, and comparison of disassembly of installed shared libraries). libc changes because of the PLT entry for the newly exported __libc_pread; librt changes because of assertion line numbers and PLT rearrangement; other stripped installed shared libraries do not change. [BZ #18519] * posix/Versions (libc): Export __libc_pread at version GLIBC_PRIVATE. * sysdeps/pthread/aio_misc.c (handle_fildes_io): Call __libc_pread instead of pread. * conform/Makefile (test-xfail-POSIX/aio.h/linknamespace): Remove variable.

2014-12-06Fix pthreads getrlimit, gettimeofday namespace (bug 17682).Joseph Myers
Some pthreads functions use getrlimit and gettimeofday, but these functions are XSI, not base POSIX; this is a namespace issue for dynamic linking as well as static linking. This patch makes them use __getrlimit and __gettimeofday instead - the former needed to be newly exported from libc.so at GLIBC_PRIVATE (and so now needs libc_hidden_proto / libc_hidden_def), the latter was already exported. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17682] * resource/Versions (libc): Add __getrlimit at GLIBC_PRIVATE. * resource/getrlimit.c (__getrlimit): Use libc_hidden_def. * sysdeps/mach/hurd/getrlimit.c (__getrlimit): Likewise. * include/sys/resource.h (__getrlimit): Use libc_hidden_proto. * nptl/nptl-init.c (__pthread_initialize_minimal_internal): Use __getrlimit instead of getrlimit. * nptl/pthread_cond_timedwait.c (__pthread_cond_timedwait): Use __gettimeofday instead of gettimeofday. * nptl/pthread_rwlock_timedrdlock.c (pthread_rwlock_timedrdlock): Likewise. * nptl/pthread_rwlock_timedwrlock.c (pthread_rwlock_timedwrlock): Likewise. * sysdeps/pthread/aio_misc.c (handle_fildes_io): Likewise. * conform/Makefile (test-xfail-POSIX2008/aio.h/linknamespace): Remove variable. (test-xfail-POSIX2008/pthread.h/linknamespace): Likewise. (test-xfail-POSIX2008/time.h/linknamespace): Likewise.
