Struct VerifyOracle

pub struct VerifyOracle<A: Arch, O1: Oracle<A>, O2: Oracle<A>>(/* private fields */);
Expand description

An oracle that observes execution on two oracles, and panics if the results are not identical.

Implementations§

§

impl<A: Arch, O1: Oracle<A>, O2: Oracle<A>> VerifyOracle<A, O1, O2>

pub fn new(o1: O1, o2: O2) -> VerifyOracle<A, O1, O2>

Creates a new VerifyOracle, which verifies the observations of o1 against the observations of o2.

Trait Implementations§

§

impl<A: Arch, O1: Oracle<A>, O2: Oracle<A>> Oracle<A> for VerifyOracle<A, O1, O2>

§

const UNRELIABLE_INSTRUCTION_FETCH_ERRORS: bool = _

Set to true if the instruction fetch errors are unreliable.
§

type MappableArea = DoubleCheckedMappableArea<<O1 as Oracle<A>>::MappableArea, <O2 as Oracle<A>>::MappableArea>

The memory addresses that can be mapped by this oracle.
§

fn mappable_area(&self) -> Self::MappableArea

Returns the memory addresses that can be mapped by this oracle.
§

fn page_size(&mut self) -> u64

Returns the page size of the oracle.
§

fn observe( &mut self, before: &SystemState<A>, ) -> Result<SystemState<A>, OracleError>

Observes the output state after executing a single instruction in the before state.
§

fn scan_memory_accesses( &mut self, before: &SystemState<A>, ) -> Result<Vec<Addr>, OracleError>

Uses debugging registers to determine all memory addresses accessed by the instruction. If this is not supported, returns an empty Vec.
§

fn debug_dump(&mut self)

Prints debugging information about the oracle.
§

fn restart(&mut self)

Restart the oracle, if possible.
§

fn kill(self)

Kills the oracle, if possible.
§

fn batch_observe_iter<'a, S: AsSystemState<A> + 'a, I: IntoIterator<Item = S> + 'a>( &'a mut self, states: I, ) -> impl Iterator<Item = Observation<S, A>>

Performs many observations in one go. Behaves idential to Self::observe, but is much more efficient.
§

fn batch_observe_gpreg_only_iter<'a, S: AsSystemState<A> + 'a, I: IntoIterator<Item = S> + 'a>( &'a mut self, states: I, ) -> impl Iterator<Item = Observation<S, A>>

Performs many observations in one go. Only reads and writes the general-purpose registers. Other registers may have arbitrary values.
§

fn random_mappable_page(&self, rng: &mut impl Rng) -> Page<A>

Returns a random mappable page.
§

fn observe_carefully( &mut self, before: &SystemState<A>, ) -> Result<SystemState<A>, OracleError>

Observes the output state after executing a single instruction in the before state. If possible, uses debugging registers to exhaustively check the exact memory locations that are accessed. Returns a memory access error if a memory is accessed that is not set in before. Read more
§

fn batch_observe<'a, const N: usize, S: AsSystemState<A> + 'a>( &mut self, states: [S; N], ) -> [Observation<S, A>; N]

Performs many observations in one go. Behaves idential to Self::observe, but is much more efficient.
