Many hardened allocators xor the next pointer `p` +with a secret key `k1`, as `p^k1`. This prevents overwriting with known +values but might be still too weak: if the attacker can guess +the pointer `p` this can reveal `k1` (since `p^k1^p == k1`). +Moreover, if multiple blocks can be read as well, the attacker can +xor both as `(p1^k1) ^ (p2^k1) == p1^p2` which may reveal a lot +about the pointers (and subsequently `k1`). + +Instead mimalloc uses an extra key `k2` and encodes as `((p^k2)<<<k1)+k1`. +Since these operations are not associative, the above approaches do not +work so well any more even if the `p` can be guesstimated. For example, +for the read case we can subtract two entries to discard the `+k1` term, +but that leads to `((p1^k2)<<<k1) - ((p2^k2)<<<k1)` at best. +We include the left-rotation since xor and addition are otherwise linear +in the lowest bit. Finally, both keys are unique per page which reduces +the re-use of keys by a large factor. + +We also pass a separate `null` value to be used as `NULL` or otherwise +`(k2<<<k1)+k1` would appear (too) often as a sentinel value. +------------------------------------------------------------------- */ + +static inline bool mi_is_in_same_segment(const void* p, const void* q) { + return (_mi_ptr_segment(p) == _mi_ptr_segment(q)); +} + +static inline bool mi_is_in_same_page(const void* p, const void* q) { + mi_segment_t* segment = _mi_ptr_segment(p); + if (_mi_ptr_segment(q) != segment) return false; + // assume q may be invalid // return (_mi_segment_page_of(segment, p) == _mi_segment_page_of(segment, q)); + mi_page_t* page = _mi_segment_page_of(segment, p); + size_t psize; + uint8_t* start = _mi_segment_page_start(segment, page, &psize); + return (start <= (uint8_t*)q && (uint8_t*)q < start + psize); +} + +static inline uintptr_t mi_rotl(uintptr_t x, uintptr_t shift) { + shift %= MI_INTPTR_BITS; + return (shift==0 ? x : ((x << shift) | (x >> (MI_INTPTR_BITS - shift)))); +} +static inline uintptr_t mi_rotr(uintptr_t x, uintptr_t shift) { + shift %= MI_INTPTR_BITS; + return (shift==0 ? x : ((x >> shift) | (x << (MI_INTPTR_BITS - shift)))); +} + +static inline void* mi_ptr_decode(const void* null, const mi_encoded_t x, const uintptr_t* keys) { + void* p = (void*)(mi_rotr(x - keys[0], keys[0]) ^ keys[1]); + return (p==null ?
