2021-03-25 | Slab: head now uses bitmask for used/free nodes info instead of lists | Maria Matejka | |
From now, there are no auxiliary pointers stored in the free slab nodes. This led to strange debugging problems if use-after-free happened in slab-allocated structures, especially if the structure's first member is a next pointer. This also reduces the memory needed by 1 pointer per allocated object. OTOH, we now rely on pages being aligned to their size's multiple, which is quite common anyway. |
