2015-09-17Use __pthread_setcancelstate in libc.aH.J. Lu
This patch references __pthread_setcancelstate instead of pthread_setcancelstate in libc.a. [BZ #18970] * misc/error.c (error): Replace pthread_setcancelstate with __pthread_setcancelstate. (error_at_line): Likewise. * posix/wordexp.c (parse_comm): Likewise. * stdlib/fmtmsg.c (fmtmsg): Likewise. * nptl/forward.c (pthread_setcancelstate): Renamed to ... (__pthread_setcancelstate): This. (pthread_setcancelstate): Add an alias. * nptl/nptl-init.c (pthread_functions): Replace ptr_pthread_setcancelstate with ptr___pthread_setcancelstate. * sysdeps/nptl/pthread-functions.h (pthread_functions): Likewise. * nptl/pthreadP.h (__pthread_setcancelstate): Mark it with hidden_proto. * nptl/pthread_setcancelstate.c (__pthread_setcancelstate): Mark it with hidden_def. * sysdeps/nptl/libc-lockP.h (__pthread_setcancelstate): New. (pthread_setcancelstate): Renamed to ... (__pthread_setcancelstate): This. * sysdeps/unix/sysv/linux/fatal-prepare.h (FATAL_PREPARE): Use __libc_ptf_call with __pthread_setcancelstate.
2015-07-10Add and use new glibc-internal futex API.Torvald Riegel
This adds new functions for futex operations, starting with wait, abstimed_wait, reltimed_wait, wake. They add documentation and error checking according to the current draft of the Linux kernel futex manpage. Waiting with absolute or relative timeouts is split into separate functions. This allows for removing a few cases of code duplication in pthreads code, which uses absolute timeouts; also, it allows us to put platform-specific code to go from an absolute to a relative timeout into the platform-specific futex abstractions.. Futex operations that can be canceled are also split out into separate functions suffixed by "_cancelable". There are separate versions for both Linux and NaCl; while they currently differ only slightly, my expectation is that the separate versions of lowlevellock-futex.h will eventually be merged into futex-internal.h when we get to move the lll_ functions over to the new futex API.

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.

Replace bespoke code to align a value with the ALIGN_UP macro to make it easier to read.

2014-07-11nptl: Fix abort in case of set*id failure [BZ #17135]Florian Weimer
If a call to the set*id functions fails in a multi-threaded program, the abort introduced in commit 13f7fe35ae2b0ea55dc4b9628763aafdc8bdc30c was triggered. We address by checking that all calls to set*id on all threads give the same result, and only abort if we see success followed by failure (or vice versa).
2014-04-01Check for syscall error in the SETXID implementation in NPTL (bug 13347).Florian Weimer
At this point, we can only abort the process because we have already switched credentials on other threads. Returning an error would still leave the process in an inconsistent state. The new xtest needs root privileges to run.

2013-06-15New API to set default thread attributesSiddhesh Poyarekar
This patch introduces two new convenience functions to set the default thread attributes used for creating threads. This allows a programmer to set the default thread attributes just once in a process and then run pthread_create without additional attributes.
2013-03-19Move __default_stacksize into __default_pthread_attrSiddhesh Poyarekar
Make __default_pthread_attr object to store default attribute values for threads.
2013-03-01Revert GLIBC_PTHREAD_DEFAULT_STACKSIZE changes.Carlos O'Donell
This reverts the change that allows the POSIX Thread default stack size to be changed by the environment variable GLIBC_PTHREAD_DEFAULT_STACKSIZE. It has been requested that more discussion happen before this change goes into 2.18.

New environment variable GLIBC_PTHREAD_DEFAULT_STACKSIZE to do this.
