Alan Carvalho de Assis fb50c44d08 Fix various issues noted by Coverity 2018-02-06 09:13:16 -06:00
Gregory Nutt 82982f7972 sched/: Fix several inappropriate accesses to get_errno() that were missed in previous changes (some going back to nuttx-.23). Add new nxsched_setscheduler() and nxsched_getaffinity() which are equivalent to their counterparts without the nx on front. These versions do not modify the errno value. Changed all calls within the OS to use these newer versions of the functions. 2018-01-30 16:16:41 -06:00
Gregory Nutt 83cdb0c552 Squashed commit of the following: 
libc/semaphore:  Add nxsem_getvalue() which is identical to sem_getvalue() except that it never modifies the errno variable.  Changed all references to sem_getvalue in the OS to nxsem_getvalue().

    sched/semaphore:  Rename all internal private functions from sem_xyz to nxsem_xyz.  The sem_ prefix is (will be) reserved only for the application semaphore interfaces.

    libc/semaphore:  Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable.  Changed all references to sem_init in the OS to nxsem_init().

    sched/semaphore:  Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function.

    sched/semaphoate:  Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.

Gregory Nutt c36bf090f0 pthread: Minor logic fix in pthread_mutex_consistent. Updat some comments. 2017-04-10 10:10:41 -06:00
Gregory Nutt b51b72b2db pthreads: Re-order some operations so that mutexes are placed in the inconsistent state BEFORE the clean-up callbacks are called. 2017-04-10 08:11:16 -06:00
Gregory Nutt b07d3fc305 Rename CONFIG_MUTEX_TYPES to CONFIG_PTHREAD_MUTEX_TYPES 2017-03-27 09:08:14 -06:00
Gregory Nutt f2f798cb29 pthread mutexes: Finish logic to support configuration mutex robustness. 2017-03-27 08:50:45 -06:00
Gregory Nutt 8b23c16b90 pthreads: pthread_mutex_consistent() needs to clear flags. 2017-03-26 14:44:57 -06:00
Gregory Nutt 363403fb1f pthreads: Add more robustness characteristics: pthread_mutex_lock() and trylock() will now return EOWNERDEAD if the mutex is locked by a thread that no longer exists. Add pthread_mutex_consistent() to recover from this situation. 2017-03-26 10:35:23 -06:00
