Dmitry Muhomor 01a199e19e mte: move is_memtag_enabled to read-only allocator data 2023-10-30 14:20:53 -04:00
Dmitry Muhomor e3686ae457 add support for Arm MTE memory tagging
- tag slab allocations with [1..14] tags
- tag freed slab allocations with the "15" tag value to detect accesses to freed slab memory
- when generating tag value for a slab slot, always exclude most recent tag value for that slot
(to make use-after-free detection more reliable) and most recent tag values of its immediate
neighbors (to detect linear overflows and underflows)
