Types

type Backend

type Backend interface {
	// Called when the backend should create or begin managing a new network
	RegisterNetwork(ctx context.Context, wg sync.WaitGroup, config *subnet.Config) (Network, error)
}

Besides the entry points in the Backend interface, the backend's New() function receives static network interface information (like internal and external IP addresses, MTU, etc) which it should cache for later use if needed.

type BackendCtor added in v0.5.6

type BackendCtor func(sm subnet.Manager, ei *ExternalInterface) (Backend, error)

type ExternalInterface added in v0.5.6

type ExternalInterface struct {
	Iface     *net.Interface
	IfaceAddr net.IP
	ExtAddr   net.IP
}

type Manager added in v0.5.6

type Manager interface {
	GetBackend(backendType string) (Backend, error)
}

func NewManager added in v0.5.6

func NewManager(ctx context.Context, sm subnet.Manager, extIface *ExternalInterface) Manager

type Network added in v0.5.6

type Network interface {
	Lease() *subnet.Lease
	MTU() int
	Run(ctx context.Context)
}

type RouteNetwork added in v0.10.0

	SimpleNetwork
	BackendType string

	SM        subnet.Manager
	GetRoute  func(lease *subnet.Lease) *netlink.Route

func (*RouteNetwork) Run added in v0.10.0

func (n *RouteNetwork) Run(ctx context.Context)

type SimpleNetwork added in v0.5.6

type SimpleNetwork struct {
	SubnetLease *subnet.Lease
	ExtIface    *ExternalInterface
}

func (*SimpleNetwork) Lease added in v0.5.6
