Avoid seemingly-possible overflow By looking just at that test, it looks like 2 + dn_size could overflow. In fact that can't happen as that would mean we've read a CA cert of size is too big to be represented by a size_t. However, it's best for code to be more obviously free of overflow without having to reason about the bigger picture.
