Struct libafl::bolts::shmem::unix_shmem::ashmem::AshmemShMemProvider

pub struct AshmemShMemProvider {}

A ShMemProvider which uses ashmem to provide shared memory mappings.

Trait Implementations

impl Clone for AshmemShMemProvider

fn clone(&self) -> AshmemShMemProvider

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AshmemShMemProvider

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AshmemShMemProvider

fn default() -> Self

Returns the “default value” for a type.

impl ShMemProvider for AshmemShMemProvider

Implement ShMemProvider for AshmemShMemProvider, for the Android ShMem.

type Mem = AshmemShMem

The actual shared map handed out by this ShMemProvider.

fn new() -> Result<Self, Error>

Create a new instance of the provider

fn new_map(&mut self, map_size: usize) -> Result<Self::Mem, Error>

Create a new shared memory mapping

fn from_id_and_size(
    &mut self,
    id: ShMemId,
    size: usize
) -> Result<Self::Mem, Error>

Get a mapping given its id and size

fn from_description(
    &mut self,
    description: ShMemDescription
) -> Result<Self::Mem, Error>

Get a mapping given a description

fn clone_ref(&mut self, mapping: &Self::Mem) -> Result<Self::Mem, Error>

Create a new sharedmap reference from an existing id and len

fn existing_from_env(&mut self, env_name: &str) -> Result<Self::Mem, Error>

Reads an existing map config from env vars, then maps it

fn pre_fork(&mut self) -> Result<(), Error>

This method should be called before a fork or a thread creation event, allowing the ShMemProvider to get ready for a potential reset of thread specific info, and for potential reconnects. Make sure to call Self::post_fork() after threading!

fn post_fork(&mut self, _is_child: bool) -> Result<(), Error>

This method should be called after a fork or after cloning/a thread creation event, allowing the ShMemProvider to reset thread specific info, and potentially reconnect. Make sure to call Self::pre_fork() before threading!

fn release_map(&mut self, _map: &mut Self::Mem)

Release the resources associated with the given ShMem
