This proof demonstrates the memory safety of the TaskDelete function. The
|
|
initialization for the task to be delete and `pxCurrentTCB` is quite similar
|
|
(since the task handle may be NULL, and in that case `pxCurrentTCB` is used).
|
|
The task to be deleted requires the stack in the task control block to be
|
|
allocated, and the flag for static allocation to be properly set (i.e., valid
|
|
values as defined by the macros) Task lists are initialized with these tasks
|
|
and nondet. filled with a few more items. We assume a nondet. value for
|
|
`xSchedulerRunning`.
|
|
|
|
This proof is a work-in-progress. Proof assumptions are described in
|
|
the harness. The proof also assumes the following functions are
|
|
memory safe and have no side effects relevant to the memory safety of
|
|
this function:
|
|
|
|
* vPortCloseRunningThread
|
|
* vPortDeleteThread
|
|
* vPortEnterCritical
|
|
* vPortExitCritical
|
|
* vPortGenerateSimulatedInterrupt
