# FreeRTOS list proofs
|
||||
|
||||
The list predicates and proofs are inspired by and based on the work from
|
||||
Ferreira et al. (STTT'14).
|
||||
|
||||
The main shape predicate is a doubly-linked list segment (DLS), as defined
|
||||
by Ferreira et al. in Fig 15. A DLS is defined by two `xLIST_ITEM` struct
|
||||
pointers `n` and `m` (possibly pointing to the same item) which are the start
|
||||
and end of the segment. We track the item pointers and values within the DLS in
|
||||
the lists `cells` and `vals`, respectively. Therefore `n` and `m` are the first
|
||||
and last items of `cells`.
|
||||
|
||||
```
|
||||
+--+ +--+
|
||||
-----n-> |*n| ... |*m| -mnext->
|
||||
<-nprev- | | | | <-m-----
|
||||
+--+ +--+
|
||||
^-----------^
|
||||
DLS(n, nprev, mnext, m)
|
||||
```
|
||||
|
||||
With base case: `n == m` (single item case)
|
||||
|
||||
```
|
||||
+--+
|
||||
-----n-> |*n| -mnext->
|
||||
<-nprev- | | <-n-----
|
||||
+--+
|
||||
^--^
|
||||
xLIST_ITEM
|
||||
DLS(n, nprev, mnext, n)
|
||||
```
|
||||
|
||||
Cons case:
|
||||
|
||||
```
|
||||
+--+ +--+ +--+
|
||||
-----n-> |*n| -o-> |*o| ... |*m| -mnext->
|
||||
<-nprev- | | <-n- | | | | <-m-----
|
||||
+--+ +--+ +--+
|
||||
^--^ ^-----------^
|
||||
xLIST_ITEM DLS(o, n, mnext, m)
|
||||
|
||||
^---------------------^
|
||||
DLS(n, nprev, mnext, m)
|
||||
```
|
||||
|
||||
A DLS can be made into a well-formed list by joining `n` and `m` into a cycle.
|
||||
Note that unlike Ferreira et al.'s list shape predicate, we always start with
|
||||
the sentinel end item to avoid a top-level case-split. So in the following
|
||||
diagram the start and end of the DLS are `end` and the item-before-end
|
||||
`endprev`.
|
||||
|
||||
```
|
||||
.-----------------------------------.
|
||||
| +--------+ +--------+ |
|
||||
`--> |*end | ... |*endprev| ----'
|
||||
.---- | | | | <---.
|
||||
| +--------+ +--------+ |
|
||||
`----------------------------------'
|
||||
^-----------------------^
|
||||
DLS(end, endprev, end, endprev)
|
||||
```

|

|

* 1) Stack overflow -

* see https://www.FreeRTOS.org/Stacks-and-stack-overflow-checking.html
|

* 2) Incorrect interrupt priority assignment, especially on Cortex-M

* parts where numerically high priority values denote low actual
|
||||
* interrupt priorities, which can seem counter intuitive. See
|
||||
* https://www.FreeRTOS.org/RTOS-Cortex-M3-M4.html and the definition
|
||||
* of configMAX_SYSCALL_INTERRUPT_PRIORITY on
|

* https://www.FreeRTOS.org/a00110.html
|
||||
* 3) Calling an API function from within a critical section or when
|
||||
* the scheduler is suspended, or calling an API function that does
|
||||
* not end in "FromISR" from an interrupt.
|
||||
* 4) Using a queue or semaphore before it has been initialised or
|
||||
* before the scheduler has been started (are interrupts firing
|
||||
* before vTaskStartScheduler() has been called?).
|
||||
* 5) If the FreeRTOS port supports interrupt nesting then ensure that
|
||||
* the priority of the tick interrupt is at or below

* configMAX_SYSCALL_INTERRUPT_PRIORITY.
