https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=211802 Bug ID: 211802 Summary: pthread_mutexattr_setprioceiling fails with EINVAL if m_protocol != PTHREAD_PRIO_PROTECT Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: freebsd-bugs@FreeBSD.org Reporter: ngie@FreeBSD.org One of the new NetBSD tests initializes a pthread_mutexattr, then tests out priority ceiling manipulation via pthread_mutexattr_getprioceiling/pthread_mutexattr_setprioceiling . Unfortunately the test fails with EINVAL because of a check made in lib/libthr/thr_mutexattr.c: 230 int 231 _pthread_mutexattr_getprioceiling(pthread_mutexattr_t *mattr, int *prioceiling) 232 { 233 int ret = 0; 234 235 if (mattr == NULL || *mattr == NULL) 236 ret = EINVAL; 237 else if ((*mattr)->m_protocol != PTHREAD_PRIO_PROTECT) 238 ret = EINVAL; 239 else 240 *prioceiling = (*mattr)->m_ceiling; 241 242 return (ret); 243 } 244 245 int 246 _pthread_mutexattr_setprioceiling(pthread_mutexattr_t *mattr, int prioceiling) 247 { 248 int ret = 0; 249 250 if (mattr == NULL || *mattr == NULL) 251 ret = EINVAL; 252 else if ((*mattr)->m_protocol != PTHREAD_PRIO_PROTECT) 253 ret = EINVAL; 254 else 255 (*mattr)->m_ceiling = prioceiling; 256 257 return (ret); 258 } opengroup.org [1] and the pthread*(3) [2] manages don't state why m_protocol being set to PTHREAD_PRIO_PROTECT would cause the functions to return EINVAL. 1. https://www.freebsd.org/cgi/man.cgi?apropos=0&sektion=3&query=pthread_mutexattr&manpath=FreeBSD+7.0-current&format=html 2. http://pubs.opengroup.org/onlinepubs/009695399/functions/pthread_mutexattr_getprioceiling.html -- You are receiving this mail because: You are the assignee for the bug.
