Struct IcmpRelay 

pub struct IcmpRelay { /* private fields */ }

Relays ICMP echo requests from the guest to the real network via unprivileged ICMP sockets.

Each echo request spawns a fire-and-forget tokio task. No session table is needed — ping traffic is low-volume and each probe is independent.

Implementations

impl IcmpRelay

pub fn new( shared: Arc<SharedState>, gateway_mac: [u8; 6], guest_mac: [u8; 6], tokio_handle: Handle, ) -> Self

Create a new ICMP relay, probing for unprivileged socket support.

pub fn relay_outbound_if_echo( &self, frame: &[u8], config: &PollLoopConfig, policy: &NetworkPolicy, ) -> bool

Try to intercept an outbound frame as an ICMP echo request.

Returns true if the frame was consumed (caller should drop_staged_frame()). Returns false if the frame is not an ICMP echo request or the backend is unavailable — caller should fall through to classify_frame.
