5 years agoIncrease the MC heap size as a quickfix for the heap overflow bug
Gabriel Corona [Fri, 21 Mar 2014 11:35:13 +0000 (12:35 +0100)]
Increase the MC heap size as a quickfix for the heap overflow bug

When the model-checker is used, two heaps are used:

  * one for the application and the simulator;
  * one for the model-checker.

The heaps are initially of size STD_HEAP_SIZE (currently about
19-10MiB) and are next to each other.

In some cases, the first heap overflows into the second one leading to
curruption of the second heap. One possible symptom of this is a
freeze in malloc/sem_wait:

In strace:

    futex(0x998c000, FUTEX_WAIT, 0, NULL <unfinished ...>

The application heap overflows into the model-checker heap and memset0
the semaphore/futex at the beginning of the second heap.

The bug is triggered by commit 5a37cda with increases the default
stack size (the stacks are allocated in the application heap).

Things to change:

  Solution a:

    1) add an (optional) "hard address" to a given heap in order to
       a heap to overflow on something else;

    2) and do not place the heaps next to each other.

    The problem is that someone might mmap something in the area of
    the heaps.

  Solution b:

    mmap a very big area of memory (say 1TiB) for eac heaps and never
    grow again. Let the system allocate memory lazily.

    It might be necessary, to add a parameter fo choose this value in
    order to be able to handle very large problems.

  Solution c:

    Use segmented heaps.

    But we would need to change both the model-checker and the malloc
    implementation to do this (i.e. We don't want to do this).

Temporary workarounds:

  * either increase STD_HEAP_SIZE (in the source code);

  * or use a smaller value for the stack size
    (--cfg:contexts/stack_size=128).
