Functions ¶
func AddAddresses ¶ added in v1.6.0
func AttachContainer ¶ added in v1.6.0
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 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 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
func ListenUnixSocket ¶ added in v1.5.0
func WithNetNSLinkByPidUnsafe ¶ added in v1.6.1
func WithNetNSLinkUnsafe ¶ added in v1.6.1
func WithNetNSUnsafe ¶ added in v1.6.1
Please see https://github.com/weaveworks/weave/issues/2388#issuecomment-228365069 for more details and make sure that you understand the implications before using the function!
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
linux/ethtool.h 'struct ethtool_value'
