Struct libafl::bolts::shmem::RcShMemProvider

pub struct RcShMemProvider<T: ShMemProvider> { /* fields omitted */ }

A Refernce Counted ShMemProvider, that can use internal mutability. Useful if the ShMemProvider needs to keep local state.

Trait Implementations

impl<T: Clone + ShMemProvider> Clone for RcShMemProvider<T>

fn clone(&self) -> RcShMemProvider<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + ShMemProvider> Debug for RcShMemProvider<T>

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

Formats the value using the given formatter.

impl<T> Default for RcShMemProvider<T> where
    T: ShMemProvider + Debug, 

fn default() -> Self

Returns the “default value” for a type.

impl<T> ShMemProvider for RcShMemProvider<T> where
    T: ShMemProvider + Debug, 

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.

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

After fork, make sure everything gets set up correctly internally.

type Mem = RcShMem<T>

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 release_map(&mut self, map: &mut Self::Mem)

Release the resources associated with the given ShMem

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

Create a new sharedmap reference from an existing id and len

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

Get a mapping given a description

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

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