* BZ #12310: pthread_exit in static app. segfaultsVladimir Nikulichev2013-06-242-0/+9
| | | | | | | | | | | | | | | | Static applications that call pthread_exit on the main thread segfault. This is because after a thread terminates __libc_start_main decrements __nptl_nthreads which is only defined in pthread_create. Therefore the right solution is to add a requirement to pthread_create from pthread_exit. ~~~ nptl/ 2013-06-24 Vladimir Nikulichev <v.nikulichev@gmail.com> [BZ #12310] * pthread_exit.c: Add reference to pthread_create.
* Include <string.h> in nptl/pthread_setattr_default_np.c.Joseph Myers2013-06-222-0/+5

* PowerPC: Reserve TCB space for EBB frameworkAdhemerval Zanella2013-06-171-0/+5
| | | | | This patch reserves four pointer to be used in future Event-Based Branch framework for PowerPC.
* New API to set default thread attributesSiddhesh Poyarekar2013-06-1513-13/+643
| | | | | | | 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.
* Avoid access beyond memory bounds in pthread_attr_getaffinity_npSiddhesh Poyarekar2013-06-144-1/+80
| | | | | | | | | Resolves BZ #15618. pthread_attr_getaffinity_np may write beyond bounds of the input cpuset buffer if the size of the input buffer is smaller than the buffer present in the input pthread attributes. Fix is to copy to the extent of the minimum of the source and the destination.
* x86*: Return syscall error for lll_futex_wake.Carlos O'Donell2013-06-103-8/+17
| | | | | | | | | | | | | | | | | | | | | | It is very very possible that the futex syscall returns an error and that the caller of lll_futex_wake may want to look at that error and propagate the failure. This patch allows a caller to see the syscall error. There are no users of the syscall error at present, but future cleanups are now be able to check for the error. -- nplt/ 2013-06-10 Carlos O'Donell <carlos@redhat.com> * sysdeps/unix/sysv/linux/i386/lowlevellock.h (lll_futex_wake): Return syscall error. * sysdeps/unix/sysv/linux/x86_64/lowlevellock.h (lll_futex_wake): Return syscall error.

* sem_post.c: Include atomic.h.Carlos O'Donell2013-04-072-0/+5
| | | | | | | | | | | | | | The sem_post.c file uses atomic functions without including atomic.h. Add `#include <atomic.h>' to the file to prevent any compile time warnings when other headers change and atomic.h isn't implicitly included. --- nptl/ 2013-04-07 Carlos O'Donell <carlos@redhat.com> * sysdeps/unix/sysv/linux/sem_post.c: Include atomic.h.
* Fix static build when configured with --disable-hidden-pltSiddhesh Poyarekar2013-04-042-1/+9
| | | | | | | | | | | | | | | Fixes BZ #15337. Static builds fail with the following warning: /home/tools/glibc/glibc/nptl/../nptl/sysdeps/unix/sysv/linux/x86_64/cancellation.S:80: undefined reference to `__GI___pthread_unwind' When the source is configured with --disable-hidden-plt. This is because the preprocessor conditional in cancellation.S only checks if the build is for SHARED, whereas hidden_def is defined appropriately only for a SHARED build that will have symbol versioning *and* hidden defs are enabled. The last case is false here.

* C++11 thread_local destructors supportSiddhesh Poyarekar2013-02-181-0/+3
| | | | | | | | | | | This feature is specifically for the C++ compiler to offload calling thread_local object destructors on thread program exit, to glibc. This is to overcome the possible complication of destructors of thread_local objects getting called after the DSO in which they're defined is unloaded by the dynamic linker. The DSO is marked as 'unloadable' if it has a constructed thread_local object and marked as 'unloadable' again when all the constructed thread_local objects defined in it are destroyed.
