> However, this turns out to be impossible (as far as I know) because of a side effect of the ps4 page size being changed to 0x4000 bytes (from the normal of 0x1000). It appears that in order to change the page size globally, the ps4 kernel developers opted to directly change the related macros. One of the many changes resulting from this is that the smallest actual amount of memory which malloc may give back to a caller becomes 0x40 bytes. While this also results in tons of memory being completely wasted, it does serve to nullify certain exploitation techniques (likely completely by accident…). This is pretty cool (and probably obvious to a lot of people) as a security technique. Could this be done for consumer OSes? 64 bytes as the smallest malloc-able size doesn't seem too bad for today's ultrabooks...
