DepEnforcement

Struct DepEnforcement 

Source
pub struct DepEnforcement { /* private fields */ }
Expand description

DEP (Data Execution Prevention) / NX enforcement.

Tracks pages that should have the NX bit set and provides helpers for ensuring data pages are not executable.

Implementations§

Source§

impl DepEnforcement

Source

pub fn new() -> Self

Source

pub fn should_set_nx(&self, region: RegionType) -> bool

Determine whether a page at the given address should have NX set.

Data, heap, and stack pages should always be non-executable.

Source

pub fn enforce_flags(&self, flags: u64, region: RegionType) -> u64

Apply NX bit to page table entry flags.

Returns the flags with NO_EXECUTE added if the region type warrants it.
