Struct libafl::bolts::shmem::unix_shmem::MmapShMemProvider

pub struct MmapShMemProvider { /* private fields */ }

A ShMemProvider which uses shmget/shmat/shmctl to provide shared memory mappings.

Trait Implementations

impl Clone for MmapShMemProvider

fn clone(&self) -> MmapShMemProvider

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MmapShMemProvider

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

Formats the value using the given formatter.

impl Default for MmapShMemProvider

fn default() -> Self

Returns the “default value” for a type.

impl ShMemProvider for MmapShMemProvider

Implement ShMemProvider for MmapShMemProvider.

type ShMem = MmapShMem

The actual shared map handed out by this ShMemProvider.

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

Create a new instance of the provider

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

Create a new shared memory mapping

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

Get a mapping given its id and size

fn new_shmem_object<T: Sized + 'static>(&mut self) -> Result<Self::ShMem, Error>

Create a new shared memory mapping to hold an object of the given type

fn shmem_object_from_id<T: Sized + 'static>(
    &mut self,
    id: ShMemId
) -> Result<Self::ShMem, Error>

Get a mapping given its id to hold an object of the given type

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

Get a mapping given a description

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

Create a new sharedmap reference from an existing id and len

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

Release the resources associated with the given ShMem
