2021-06-21vppinfra: asan: fix overflow supportBenoît Ganne1-0/+7
In some part of VPP we are accessing memory past what was allocated for efficiency when we know it is safe to do so. We need to tell ASan about it so it does not complain. The initial attempt was too simple and could not manage cases where the poisoned memory was scattered. This new attempt is more robust as we save and restore the full shadow state. Note it will still not work properly if we poison/unpoison memory while in an overflow context, but this should not be a big issue as overflow should only be temporary.
