synthetic workloads have measured as high as 8%.
-config INIT_MLOCKED_ON_FREE_DEFAULT_ON
- bool "Enable mlocked memory zeroing on free"
- depends on !KMSAN
- help
- This config has the effect of setting "init_mlocked_on_free=1"
- on the kernel command line. If it is enabled, all mlocked process
- memory is zeroed when freed. This restriction to mlocked memory
- improves performance over "init_on_free" but can still be used to
- protect confidential data like key material from content exposures
- to other processes, as well as live forensics and cold boot attacks.
- Any non-mlocked memory is not cleared before it is reassigned. This
- configuration can be overwritten by setting "init_mlocked_on_free=0"
- on the command line. The "init_on_free" boot option takes
- precedence over "init_mlocked_on_free".
