13d9383679 Group binding needs to be cleared before sched_releasetcb(), as otherwise group_leave() will be called and group->tg_nmembers decremented or group being released. group_leave() should be called only after group_join() is called, not after group_bind().

d8db596b3b POSIX message queues: Move mq_setattr() and mq_getattr() from nuttx/libc/mqueue to nuttx/sched/mqueue. Also add sysyscall support for mq_setattr() and mq_getattr(). This is necessary in protected and kernel builds because in those cases the message queue structure is protect and cannot be accessed directly from user mode code.

4417728955 Re-implemened pthread_kill(). It as just a simple wrapper around kill() but since the correct dispatching of singles for multi-threaded task groups has been implemented, calling kill() does no work. The corrected implementation of pthread_kill() will direct the signal specifically to the specific pthread and no other. 2015-05-13 14:43:43 -06:00

8840102554 Networking: Divide net_intiialize() into net_setup() and net_initialize() to solve a chicken-and-egg problem. net_setup() must be caleld before up_initialize() is called so that networking data structures are ready to register new network devices. 
net_initialize() now does only timer related operations and is called AFTER up_initialize() where the timers are configured.  This is really.

d9f960e97b Fix a problem in clock_systimer64 that occurs when (1) the 64-bit system time is enabled, and (2) the value of CONFIG_USEC_PER_TICK is less than 1 millisconds (such as when using the tickless mode of operation). In that case, the convertion of time to 64-bit millisecond value in clock_systmer64() causes some bad times to be returned. Time was converted to milliseconds, then to configured ticks. Precision was lost in the millisecond convertion. 
The fix is to first convert time to a 64-bit microsecond value, then to the configured tick value.

147042218b gettimeofday() and settimeofday(): Move gittimeofdady() from sched/clock to libc/time. All remove gettimeofday() from NuttX system calls. It is only a wrapper around clock_settime() and does not need a trap. gettimeofday() is no longer tried as a core OS interface. 
gettimeofday has been decremented in POSIX 2008.  settimeofday() was never part of POSIX, but I decided to add it to libc as well just for symmetry.

826f5516ff Semaphores: sem_waitirq.c must be built when signals are disabled. That is because not handles not only the case of semaphore wait being awakened by a signal, but also the case with sem_timedwait.c when the semaphore wait is awakened by a timeout. 2014-12-28 15:03:12 -06:00

937f9f23f1 strncpy will not copy the terminating \0 into the destination if the source is larger than the size of the destination. Ensure that the last byte is always zero and let strncpy only copy CONFIG_TASK_NAME_SIZE bytes.

8c28718bcb alling mq_timedreceived with immediate timeout was getting stuck and not 
timeout. Immediate timeout is achieved by setting absolute timeout value to
past time, for example abstime={ .tv_sec=0, .tv_nsec=0 }. However absolute
time was converted to relative time using unsigned integer arithmetic and
resulted large ticks count by clock_abstime2ticks, instead of expected negative
ticks value.

Patch corrects clock_abstime2ticks to return negative ticks, if absolute time
is in the past.
