Struct selinux_policy::parsed_policy::ParsedPolicy

pub struct ParsedPolicy<PS: ParseStrategy> { /* private fields */ }

A parsed binary policy.

Implementations

impl<PS: ParseStrategy> ParsedPolicy<PS>

pub fn policy_version(&self) -> u32

The policy version stored in the underlying binary policy.

pub fn handle_unknown(&self) -> &HandleUnknown

The way “unknown” policy decisions should be handed according to the underlying binary policy.

pub fn is_explicitly_allowed_custom( &self, source_type: TypeId, target_type: TypeId, target_class_name: &str, permission_name: &str ) -> Result<bool, QueryError>

Returns whether the input types are explicitly granted the permission named permission_name via an allow [...]; policy statement, or an error if looking up the input types fails. This is the “custom” form of this API because permission_name is associated with a selinux_common::AbstractPermission::Custom::permission value.

pub fn compute_explicitly_allowed_custom( &self, source_type_name: TypeId, target_type_name: TypeId, target_class_name: &str ) -> Result<AccessVector, QueryError>

Computes the access vector that associates type source_type_name and target_type_name via an explicit allow [...]; statement in the binary policy. Computes AccessVector::NONE if no such statement exists. This is the “custom” form of this API because target_class_name is associated with a selinux_common::AbstractObjectClass::Custom value.
