Functions ¶

func IPMasq4Map ¶

func IPMasq4Map(registry *metrics.Registry) *bpf.Map

func IPMasq6Map ¶

func IPMasq6Map(registry *metrics.Registry) *bpf.Map

Types ¶

type IPMasqBPFMap ¶

type IPMasqBPFMap struct {
	MetricsRegistry *metrics.Registry
}

func (*IPMasqBPFMap) Delete ¶

func (m *IPMasqBPFMap) Delete(cidr netip.Prefix) error

func (*IPMasqBPFMap) Dump ¶

func (*IPMasqBPFMap) Dump() ([]netip.Prefix, error)

Dump dumps the contents of the ip-masq-agent maps for IPv4 and/or IPv6, as required based on configuration options.

func (*IPMasqBPFMap) DumpForProtocols ¶

func (*IPMasqBPFMap) DumpForProtocols(ipv4Needed, ipv6Needed bool) ([]netip.Prefix, error)

DumpForProtocols dumps the contents of the ip-masq-agent maps for IPv4 and/or IPv6, as requested by the caller. Given that the package does not expose the maps directly, it's necessary to specify which protocol we need when ipMasq4Map/ipMasq6Map, or config options, have not been set, as is the case when calling from the CLI, for example.

func (*IPMasqBPFMap) Update ¶

func (m *IPMasqBPFMap) Update(cidr netip.Prefix) error

type Key4 ¶

type Key4 struct {
	PrefixLen uint32
	Address   types.IPv4
}

func (*Key4) New ¶

func (k *Key4) New() bpf.MapKey

func (*Key4) String ¶

func (k *Key4) String() string

type Key6 ¶

type Key6 struct {
	PrefixLen uint32
	Address   types.IPv6
}

func (*Key6) New ¶

func (k *Key6) New() bpf.MapKey

func (*Key6) String ¶

func (k *Key6) String() string

type Value ¶

type Value struct {
	Pad uint8 // not used
}

func (*Value) New ¶

func (v *Value) New() bpf.MapValue

func (*Value) String ¶

func (v *Value) String() string
