Functions ¶
func AddAddresses ¶ added in v1.6.0
func AddRoute ¶ added in v1.6.0
func AttachContainer ¶ added in v1.6.0
func AttachContainer(netNSPath, id, ifName, bridgeName string, mtu int, withMulticastRoute bool, cidrs []*net.IPNet, keepTXOn bool, hairpinMode bool) error
NB: This function can be used only by a process that terminates immediately
after calling the function as it changes netns via WithNetNSLinkUnsafe.
func CheckAddressOverlap ¶ added in v1.1.0
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
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 ConfigureARPCache ¶ added in v1.6.0
Configure the ARP cache parameters for the given interface. This makes containers react more quickly to a change in the MAC address associated with an IP address.
func ConnectedToBridgeVethPeerIds ¶ added in v1.8.0
ConnectedToBridgeVethPeerIds returns peer indexes of veth links connected to the given bridge. The peer index is used to query from a container netns whether the container is connected to the bridge.
func CreateAndAttachVeth ¶ added in v1.6.0
func CreateAndAttachVeth(name, peerName, bridgeName string, mtu int, keepTXOn bool, init func(peer netlink.Link) error) (*netlink.Veth, error)
create and attach a veth to the Weave bridge
func DetachContainer ¶ added in v1.6.0
NB: This function can be used only by a process that terminates immediately
after calling the function as it changes netns via WithNetNSLinkUnsafe.
func DetectHairpin ¶ added in v1.8.2
func EnsureInterface ¶
Wait for an interface to come up.
func EnsureInterfaceAndMcastRoute ¶ added in v1.1.0
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.
func EthtoolTXOff ¶ added in v1.6.0
Disable TX checksum offload on specified interface
