Daniel Micay	e03579253a	preserve PROT_MTE when releasing memory	2024-10-12 03:19:16 -04:00
Daniel Micay	aa950244f8	reuse code for memory_map_mte ... This drops the separate error message since that doesn't seem useful.	2024-10-12 03:18:36 -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)	2023-10-30 14:20:53 -04:00
jvoisin	b511696c55	clean up includes and remove non-portable includes ... This marginally increases the portability of hardened_malloc, eg. on OSX.	2022-02-07 07:14:51 -05:00
