Struct HandlerCtx

Source

pub struct HandlerCtx {
    pub notif: SeccompNotif,
    pub notif_fd: RawFd,
}

Expand description

Context passed to Handler::handle.

notif is the kernel notification (owned by value — it’s a small repr(C) struct, cheap to copy). notif_fd is the supervisor’s seccomp listener fd, used by helpers like read_child_mem / write_child_mem / read_child_cstr for TOCTOU-safe child memory access.

Handler state lives on the implementor (&self). Supervisor-internal state is intentionally not exposed here so the SupervisorCtx internal fields are not part of the downstream extension contract.
