Struct CapSpaceModel 

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

Capability space model (per-process capability table)

Implementations§

Source§

impl CapSpaceModel

Source

pub fn new() -> Self

Create a new capability space

Source

pub fn create_root(&mut self, rights: u32, owner: u64) -> CapabilityModel

Create a root capability (only the kernel can do this)

Source

pub fn derive( &mut self, parent_token: u64, child_rights: u32, child_owner: u64, ) -> Result<CapabilityModel, CapModelError>

Derive a child capability from a parent

Source

pub fn revoke(&mut self, token: u64) -> Result<usize, CapModelError>

Revoke a capability and all its descendants

Source

pub fn lookup(&self, token: u64) -> Option<&CapabilityModel>

Look up a capability by token

Source

pub fn validate( &self, token: u64, expected_gen: u32, ) -> Result<&CapabilityModel, CapModelError>

Validate that a token is still valid (correct generation)

Source

pub fn count(&self) -> usize

Get the number of capabilities

Source

pub fn revocation_log(&self) -> &[u64]

Get the revocation log
