Functions ¶

func AddAddresses ¶ added in v1.6.0

func AddAddresses(link netlink.Link, cidrs []*net.IPNet) (newAddrs []*net.IPNet, err error)

func AddRoute ¶ added in v1.6.0

func AddRoute(link netlink.Link, scope netlink.Scope, dst *net.IPNet, gw net.IP) error

func AttachContainer ¶ added in v1.6.0

func AttachContainer(ns netns.NsHandle, id, ifName, bridgeName string, mtu int, withMulticastRoute bool, cidrs []*net.IPNet, keepTXOn bool) error

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 ConfigureARPCache ¶ added in v1.6.0

func ConfigureARPCache(name string) error

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 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

func DetachContainer(ns netns.NsHandle, id, ifName string, cidrs []*net.IPNet) error

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.

func EthtoolTXOff ¶ added in v1.6.0

func EthtoolTXOff(name string) error

Disable TX checksum offload on specified interface

func ListenUnixSocket ¶ added in v1.5.0

func ListenUnixSocket(pathname string) (net.Listener, error)

func WithNetNS ¶ added in v1.6.0

func WithNetNS(ns netns.NsHandle, work func() error) error

func WithNetNSLink ¶ added in v1.6.0

func WithNetNSLink(ns netns.NsHandle, ifName string, work func(link netlink.Link) error) error

Types ¶

type BridgeType ¶ added in v1.6.0

type BridgeType int

const (
	WeaveBridgeName = "weave"
	DatapathName    = "datapath"

	None BridgeType = iota
	Bridge
	Fastdp
	BridgedFastdp
	Inconsistent
)

func DetectBridgeType ¶ added in v1.6.0

func DetectBridgeType(weaveBridgeName, datapathName string) BridgeType

type EthtoolValue ¶ added in v1.6.0

type EthtoolValue struct {
	Cmd  uint32
	Data uint32
}

linux/ethtool.h 'struct ethtool_value'

type IFReqData ¶ added in v1.6.0

type IFReqData struct {
	Name [IFNAMSIZ]byte
	Data uintptr
}

linux/if.h 'struct ifreq'
