Types

type NetLinkHandler

type NetLinkHandler struct {
}

NetLinkHandler is accessor for Netlink methods.

func NewNetLinkHandler

func NewNetLinkHandler() *NetLinkHandler

NewNetLinkHandler creates new instance of Netlink handler.

func (*NetLinkHandler) AddStaticRoute

func (h *NetLinkHandler) AddStaticRoute(route *netlink.Route) error

AddStaticRoute creates the new static route

func (*NetLinkHandler) DelARPEntry

func (h *NetLinkHandler) DelARPEntry(arpEntry *netlink.Neigh) error

DelARPEntry removes an static ARP entry

func (*NetLinkHandler) DelStaticRoute

func (h *NetLinkHandler) DelStaticRoute(route *netlink.Route) error

DelStaticRoute removes the static route

func (*NetLinkHandler) GetARPEntries

func (h *NetLinkHandler) GetARPEntries(interfaceIdx int) ([]netlink.Neigh, error)

GetARPEntries reads all configured static ARP entries for given interface. <interfaceIdx> works as filter, if set to zero, all arp entries in the namespace are returned

func (*NetLinkHandler) GetStaticRoutes

func (h *NetLinkHandler) GetStaticRoutes(interfaceIdx int) (v4Routes, v6Routes []netlink.Route, err error)

GetStaticRoutes reads all configured static routes with the given outgoing interface. <interfaceIdx> works as filter, if set to zero, all routes in the namespace are returned.

func (*NetLinkHandler) ReplaceStaticRoute

func (h *NetLinkHandler) ReplaceStaticRoute(route *netlink.Route) error

ReplaceStaticRoute removes the static route

func (*NetLinkHandler) SetARPEntry

func (h *NetLinkHandler) SetARPEntry(arpEntry *netlink.Neigh) error

SetARPEntry updates existing arp entry

type NetlinkAPI

type NetlinkAPI interface {
	NetlinkAPIWrite
	NetlinkAPIRead
}

NetlinkAPI interface covers all methods inside linux calls package needed to manage linux ARP entries and routes.

type NetlinkAPIRead

type NetlinkAPIRead interface {
	// GetARPEntries reads all configured static ARP entries for given interface.
	// <interfaceIdx> works as filter, if set to zero, all arp entries in the namespace
	// are returned.
	GetARPEntries(interfaceIdx int) ([]netlink.Neigh, error)

	// GetStaticRoutes reads all configured static routes with the given outgoing
	// interface.
	// <interfaceIdx> works as filter, if set to zero, all routes in the namespace
	// are returned.
	GetStaticRoutes(interfaceIdx int) (v4Routes, v6Routes []netlink.Route, err error)
}

NetlinkAPIRead interface covers read methods inside linux calls package needed to manage linux ARP entries and routes.

type NetlinkAPIWrite

type NetlinkAPIWrite interface {
	/* ARP */
	// SetARPEntry adds/modifies existing linux ARP entry.
	SetARPEntry(arpEntry *netlink.Neigh) error
	// DelARPEntry removes linux ARP entry.
	DelARPEntry(arpEntry *netlink.Neigh) error

	/* Routes */
	// AddStaticRoute adds new linux static route.
	AddStaticRoute(route *netlink.Route) error
	// ReplaceStaticRoute changes existing linux static route.
	ReplaceStaticRoute(route *netlink.Route) error
	// DelStaticRoute removes linux static route.
	DelStaticRoute(route *netlink.Route) error
}

NetlinkAPIWrite interface covers write methods inside linux calls package needed to manage linux ARP entries and routes.
