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)	2023-10-30 14:20:53 -04:00

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)
