Functions ¶
func AddDefaultRoute ¶
AddDefaultRoute sets the default route on the given gateway.
func AddHostRoute ¶
AddHostRoute adds a host-scoped route to a device.
func Cmp ¶ added in v0.6.0
Cmp compares two IPs, returning the usual ordering: a < b : -1 a == b : 0 a > b : 1
func DelLinkByName ¶
DelLinkByName removes an interface link.
func DelLinkByNameAddr ¶
DelLinkByNameAddr remove an interface and returns its addresses
func EnableForward ¶ added in v0.6.0
EnableForward will enable forwarding for all configured address families
func EnableIP4Forward ¶
func EnableIP4Forward() error
func EnableIP6Forward ¶
func EnableIP6Forward() error
func GetVethPeerIfindex ¶ added in v0.8.0
GetVethPeerIfindex returns the veth link object, the peer ifindex of the veth, or an error. This peer ifindex will only be valid in the peer's network namespace.
func RandomVethName ¶
RandomVethName returns string "veth" with random prefix (hashed from entropy)
func RenameLink ¶ added in v0.6.0
func SetHWAddrByIP ¶ added in v0.6.0
func SettleAddresses ¶ added in v0.6.0
SettleAddresses waits for all addresses on a link to leave tentative state. This is particularly useful for ipv6, where all addresses need to do DAD. There is no easy way to wait for this as an event, so just loop until the addresses are no longer tentative. If any addresses are still tentative after timeout seconds, then error.
func SetupIPMasq ¶
SetupIPMasq installs iptables rules to masquerade traffic coming from ip of ipn and going outside of ipn
func SetupVeth ¶
SetupVeth sets up a pair of virtual ethernet devices. Call SetupVeth from inside the container netns. It will create both veth devices and move the host-side veth into the provided hostNS namespace. On success, SetupVeth returns (hostVeth, containerVeth, nil)
func SetupVethWithName ¶ added in v0.8.2
func SetupVethWithName(contVethName, hostVethName string, mtu int, hostNS ns.NetNS) (net.Interface, net.Interface, error)
SetupVethWithName sets up a pair of virtual ethernet devices. Call SetupVethWithName from inside the container netns. It will create both veth devices and move the host-side veth into the provided hostNS namespace. hostVethName: If hostVethName is not specified, the host-side veth name will use a random string. On success, SetupVethWithName returns (hostVeth, containerVeth, nil)
func TeardownIPMasq ¶
TeardownIPMasq undoes the effects of SetupIPMasq
func ValidateExpectedInterfaceIPs ¶ added in v0.8.0
func ValidateExpectedRoute ¶ added in v0.8.0
