Functions

func CheckAddressOverlap added in v1.1.0

func CheckAddressOverlap(addr net.IP, ignoreIfaceNames map[string]struct{}) error

For a specific address, we only care if it is actually *inside* an existing route, because weave-local traffic never hits IP routing.

func CheckNetworkFree added in v1.0.0

func CheckNetworkFree(subnet *net.IPNet, ignoreIfaceNames map[string]struct{}) error

A network is considered free if it does not overlap any existing routes on this host. This is the same approach taken by Docker.

func EnsureInterface

func EnsureInterface(ifaceName string) (*net.Interface, error)

Wait for an interface to come up.

func EnsureInterfaceAndMcastRoute added in v1.1.0

func EnsureInterfaceAndMcastRoute(ifaceName string) (*net.Interface, error)

Wait for an interface to come up and have a route added to the multicast subnet. This matches the behaviour in 'weave attach', which is the only context in which we expect this to be called. If you change one, change the other to match.
