* add a pthread_get_name_np to match pthread_set_name_np.tedu2019-02-041-1/+7

| | | | | | | | pthread_exit from libpthread to libc, along with low-level bits to support them. Major bump to both libc and libpthread. Requested by libressl team. Ports testing by naddy@ ok kettenis@
* Use a Thread Information Block in both single and multi-threaded programs.guenther2016-05-071-7/+6
| | | | | | | | | | | | | | | | | This stores errno, the cancelation flags, and related bits for each thread and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable! Make libpthread dlopen'able by moving the cancelation wrappers into libc and doing locking and fork/errno handling via callbacks that libpthread registers when it first initializes. 'errno' *must* be declared via <errno.h> now! Clean up libpthread's symbol exports like libc. On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec. Testing by various, particularly sthen@ and patrick@ ok kettenis@
* Eliminate the need to explicitly invoke syscalls via their _thread_sys_*guenther2016-04-021-1/+3
| | | | | | | aliases by using a macro REDIRECT_SYSCALL() to map the symbols. Apply that to getthrid(), sysctl(), and issetugid() as well. ok mpi@ beck@

| | | | | | | | | thread's existing handle must continue to be valid and it didn't fully 'change' the thread handle anyway. For pthread_main_np(), use a new flag, THREAD_ORIGINAL, to indicate that the flagged thread is the original thread for *this* process. Fixes some ConsoleKit failures according to aja@
* use sysctl vm.psstrings to calculate stack bounds, rather than USRSTACK.deraadt2013-11-131-18/+31

* - Don't include guard pages in the stack size.kurt2013-03-311-7/+4
| | | | | | From Christian Schulte (cs at schulte.it) - Use stack->sp instead of recalculating it. From guenther@ okay guenther@
* Fix the handling of the stackaddr, stacksize, and guardsize attributes:guenther2012-02-181-10/+7
| | | | | | | | | | | don't try to merge values, round the sizes separately, and don't try to unmap application-supplied stacks. Copy from uthread the caching of default-sized stacks. Have pthread_attr_init() and pthread_create() get the default attributes from staticly allocated pthread_attr_t. Cache the pagesize in _rthread_init() and provide a macro for rounding to it based on suggestions from kettenis@ and tedu@, ok kettenis@
