2020-01-03cpukit/score: avoid NULL and races in priority mutex4.10Gedare Bloom2-1/+9
The PIP modifications from #3359 introduced new data structures to track priority inheritance. Prioritized mutexes without PIP share some of the code paths, and may result in NULL pointer accesses. This patch checks for NULL, and also adds ISR critical sections to an uncovered corner case during thread restarts. Closes #3829.
2018-03-23score: add Inherited_priorities priority queue and functionsGedare Bloom11-16/+271
Adds enqueue, dequeue, requeue, evaluate, and release functions for the thread priority node priority queue of inherited priorities. Add calls to these functions as needed to maintain the priority queue due to blocking, unblocking, and priority changes. Closes #3359.
2018-03-23score: replace current and real priority with priority nodeGedare Bloom14-37/+46
Encapsulate the current_priority and real_priority fields of the thread control block with a Thread_Priority_node struct. Propagate modifications throughout the tree where the two fields are directly accessed. Updates #3359.
2018-01-11score: Use _Workspace_Allocate_or_fatal_error()Sebastian Huber1-5/+8
Use _Workspace_Allocate_or_fatal_error() consistently in case auto extend is turned off. This helps to avoid undefined behaviour in _API_Mutex_Allocate() in case _API_Mutex_Information() fails.

Updates #1964.

2014-05-23score: PR2179: Fix initially locked PCP mutexesSebastian Huber1-2/+3
Elevate the priority of the creating task to the ceiling priority in case a semaphore is created as initially locked.
2013-08-26score: PR2140: Fix _Thread_queue_Process_timeout()Sebastian Huber1-8/+37
The _Thread_queue_Process_timeout() operation had several race conditions in the event of nested interrupts. Protect the critical sections via disabled interrupts.
2013-08-26score: PR2140: _Thread_queue_Extract()Sebastian Huber4-11/+14
Return if the executing context performed the extract operation since interrupts may interfere.
2013-01-07score: Fix _Objects_Shrink_information()Sebastian Huber1-20/+16
The chain iteration was wrong. The chain tail is not an object.
2012-12-06score: Critical fix for timer serverSebastian Huber1-7/+0
Under certain conditions it is possible that a call to _Watchdog_Adjust_to_chain() happens with a unit parameter value of zero (for example sptests/spintrcritical17). Remove superfluous checks that prevent an adjust to a chain of a watchdog chain which first element has a delta zero value.
