Functions

func Assert

func Assert(test bool)

Assert test is true, panic otherwise

func CheckFatal

func CheckFatal(e error)

func CheckWarn

func CheckWarn(e error)

func ConfigureARPCache

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 ErrorMessages

func ErrorMessages(errors []error) string

func LogLogger

func LogLogger() *log.Logger

func SetLogLevel

func SetLogLevel(levelname string)

func SignalHandlerLoop

func SignalHandlerLoop(ss ...SignalReceiver)

func WithNetNS

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

Types

type NetDev

type NetDev struct {
	MAC   net.HardwareAddr
	CIDRs []*net.IPNet
}

func FindNetDevs

func FindNetDevs(processID int, match func(link netlink.Link) bool) ([]NetDev, error)

Search the network namespace of a process for interfaces matching a predicate

func GetBridgeNetDev

func GetBridgeNetDev(bridgeName string) ([]NetDev, error)

Get the weave bridge interface

func GetWeaveNetDevs

func GetWeaveNetDevs(processID int) ([]NetDev, error)

Lookup the weave interface of a container

type SignalReceiver

type SignalReceiver interface {
	Stop() error
}

A subsystem/server/... that can be stopped or queried about the status with a signal
