d66fd9f965 semaphore:sem_boostholderprio prevent overrun of pend_reprios 
The second case rtcb->sched_priority <= htcb->sched_priority
  did not check if there is sufficient space in the pend_reprios
  array.

6cc8f9100b Priority Inversion fixes:typo 2017-03-10 06:37:46 -10:00

360539afac Priority inheritance: When CONFIG_SEM_PREALLOCHOLDERS==0, there is only a single, hard-allocated holder structure. This is problem because in sem_wait() the holder is released, but needs to remain in the holder container until sem_restorebaseprio() is called. The call to sem_restorebaseprio() must be one of the last things the sem_wait() does because it can cause the task to be suspended. If in sem_wait(), a new task gets the semaphore count then it will fail to allocate the holder and will not participate in priority inheritance. This fix is to add two hard-allocated holders in the sem_t structure: One of the old holder and one for the new holder. 2017-03-10 09:30:15 -06:00

c976a66f8d net/drivers/skeleton.c: Back out serialization changes of the last commit. They are not necessary in the skeleton.c example because the calls to net_lock() at the beginning of each worker function will enforce serialization. 2017-03-04 11:33:36 -06:00

c2b620b4f8 Implements support for smaller interrupt tables as described at http://www.nuttx.org/doku.php?id=wiki:howtos:smallvectors . This is largely the work of Mark Schulte. However, I have made several changes to match with the Wiki document. If you like the change, thanks go to Marc. For any errors you can blame me. 2017-03-03 09:20:25 -06:00

Provide a user defined callback context for irq's, such that when
registering a callback users can provide a pointer that will get

dca77fa06a sigtimedwait: When timer expires, up_unblock_task() is called. This is okay in the single CPU case because interrupts are disable in the timer interrupt handler. But it is insufficient in the SMP case. enter_ and leave_critical_section() must be called in order to manage spinlocks correctly. 2017-02-24 10:07:23 -06:00
