225f0b03a3 mte: move is_memtag_enabled to read-only allocator data 2023-10-28 23:32:34 +03:00
Dmitry Muhomor
52fcaf55d6 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)
