[$] Stray-write protection for persistent memory
jeudi 3 février 2022, 17:35 , par LWN.net
Persistent memory has a number of advantages; it is fast, CPU-addressable,
available in large quantities and, of course, persistent. But it also, arguably, poses a higher risk of suffering corruption as a result of bugs in the kernel. Protecting against this possibility is the objective of this patch set from Ira Weiny, which makes use of Intel's 'protection keys supervisor' (PKS) feature to make it harder for the kernel to inadvertently write to persistent memory.
