dff
A simple DFF (differential fuzzing framework).
System configuration
This fuzzer framework only supports Linux and macOS, not Windows. This is because it uses Unix Domain Sockets and Shared Memory segments for interprocess communication.
There are two limits whcih must be increased to support 100 MiB segements.
shmmax-- the max shared memory segment size.shmall-- total shared memory size in pages.
Linux
sudo sysctl -w kernel.shmmax=104857600
sudo sysctl -w kernel.shmall=256000
macOS
sudo sysctl -w kern.sysv.shmmax=104857600
sudo sysctl -w kern.sysv.shmall=256000
Usage
Go
See the examples.
Rust

Types ¶
type Client ¶
type Client struct {
// Name is the identifier sent to the server.
Name string
// Process is the callback function used to process fuzzing inputs.
Process ProcessFunc
// contains filtered or unexported fields
}
Client encapsulates the client-side behavior for connecting to the fuzzing server.
func NewClient ¶
func NewClient(name string, process ProcessFunc) *Client
NewClient creates a new Client with the given name and processing function.
func (*Client) Connect ¶
Connect establishes a connection to the fuzzing server, sends the client name, attaches to the shared memory segments, and reads the fuzzing method from the server.
type ProcessFunc ¶
ProcessFunc defines the signature for functions that process fuzzing inputs. Users of the package must supply their own function.
type Server ¶
type Server struct {
// Method is the name of the fuzzing method that will be sent to clients.
Method string
// InputProvider is a function that returns a slice of fuzzing inputs.
InputProvider func() [][]byte
// contains filtered or unexported fields
}
Server encapsulates the state of the fuzzing server.
func NewServer ¶
NewServer returns a new Server instance with the given method name and input provider.
