* nptl: Change type of __default_pthread_attrFlorian Weimer2020-06-021-2/+1
| | | | | | | | | | | | union pthread_attr_transparent has always the correct size, even if pthread_attr_t has padding that is not present in struct pthread_attr. This should not result in an observable behavioral change. The existing code appears to have been correct, but it was brittle because it was not clear which functions were allowed to write to an entire pthread_attr_t argument (e.g., by copying it).

* nptl: Change tst-typesizes to _Static_assertAdhemerval Zanella2017-11-071-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of rely on runtime check to assure correct pthread types size a better strategy would use _Static_assert to trigger an error on build time (and thus allowing to check to potentially ABI breakage on cross-compiling make check). This patch moves nptl/tst-typesizes.c to libpthread build time on each specific initialization routine and also remove some runtime redundant asserts for the same type sizes. Checked on x86_64-linux-gnu and with a build check for all affected ABIs (aarch64-linux-gnu, alpha-linux-gnu, arm-linux-gnueabihf, hppa-linux-gnu, i686-linux-gnu, ia64-linux-gnu, m68k-linux-gnu, microblaze-linux-gnu, mips64-linux-gnu, mips64-n32-linux-gnu, mips-linux-gnu, powerpc64le-linux-gnu, powerpc-linux-gnu, s390-linux-gnu, s390x-linux-gnu, sh4-linux-gnu, sparc64-linux-gnu, sparcv9-linux-gnu, tilegx-linux-gnu, tilegx-linux-gnu-x32, tilepro-linux-gnu, x86_64-linux-gnu, and x86_64-linux-x32). * nptl/pthreadP.h (ASSERT_TYPE_SIZE, ASSERT_PTHREAD_INTERNAL_SIZE): New macros. * nptl/pthread_attr_init.c (__pthread_mutex_init): Add build time checks for expected input type size. * nptl/pthread_barrier_init.c (__pthread_barrier_init): Likewise. * nptl/pthread_barrierattr_init.c (pthread_barrierattr_init): Likewise. * nptl/pthread_cond_init.c (__pthread_cond_init): Likewise. * nptl/pthread_condattr_init.c (__pthread_condattr_init): Likewise. * nptl/pthread_mutex_init.c (__pthread_mutex_init): Likewise. * nptl/pthread_mutexattr_init.c (__pthread_mutexattr_init): Likewise. * nptl/pthread_rwlock_init.c (__pthread_rwlock_init): Likewise. * nptl/pthread_rwlockattr_init.c (pthread_rwlockattr_init): Likewise. * nptl/sem_init.c (__new_sem_init, __old_sem_init): Likewise * nptl/pthread_attr_destroy.c (__pthread_attr_destroy): Remove superflous runtime assert check. * nptl/pthread_attr_getaffinity.c (__pthread_attr_getaffinity_new): Likewise. * nptl/pthread_attr_getdetachstate.c (__pthread_attr_getdetachstate): Likewise. * nptl/pthread_attr_getguardsize.c (pthread_attr_getguardsize): Likewise. * nptl/pthread_attr_getinheritsched.c (__pthread_attr_getinheritsched): Likewise. * nptl/pthread_attr_getschedparam.c (__pthread_attr_getschedparam): Likewise. * nptl/pthread_attr_getschedpolicy.c (__pthread_attr_getschedpolicy): Likewise. * nptl/pthread_attr_getscope.c (__pthread_attr_getscope): Likewise. * nptl/pthread_attr_getstack.c (__pthread_attr_getstack): Likewise. * nptl/pthread_attr_getstackaddr.c (__pthread_attr_getstackaddr): Likewise. * nptl/pthread_attr_getstacksize.c (__pthread_attr_getstacksize): Likewise. * nptl/pthread_attr_setaffinity.c (__pthread_attr_setaffinity_new): Likewise. * nptl/pthread_attr_setdetachstate.c (__pthread_attr_setdetachstate): Likewise. * nptl/pthread_attr_setguardsize.c (pthread_attr_setguardsize): Likewise. * nptl/pthread_attr_setinheritsched.c (__pthread_attr_setinheritsched): Likewise. * nptl/pthread_attr_setschedparam.c (__pthread_attr_setschedparam): Likewise. * nptl/pthread_attr_setschedpolicy.c (__pthread_attr_setschedpolicy): Likewise. * nptl/pthread_attr_setscope.c (__pthread_attr_setscope): Likewise. * nptl/pthread_attr_setstack.c (__pthread_attr_setstack, __old_pthread_attr_setstack): Likewise. * nptl/pthread_attr_setstackaddr.c (__pthread_attr_setstackaddr): Likewise. * nptl/pthread_attr_setstacksize.c (__pthread_attr_setstacksize): Likewise. * nptl/pthread_getattr_default_np.c (pthread_getattr_default_np): Likewise. * nptl/pthread_mutex_lock.c (__pthread_mutex_lock): Likewise. * nptl/pthread_setattr_default_np.c (pthread_setattr_default_np): Likewise. * nptl/tst-typesizes.c: Remove file.

* New API to set default thread attributesSiddhesh Poyarekar2013-06-151-0/+37
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.
