func BenchmarkDefrag ¶
func TestDefragBCDNS ¶
func TestDontFragBCDNS ¶
Types ¶
type IPv6Defragmenter ¶
IPv6Defragmenter is a struct which embedded a map of all fragment/packet.
func NewIPv6Defragmenter ¶
func NewIPv6Defragmenter() *IPv6Defragmenter
NewIPv6Defragmenter returns a new IPv6Defragmenter with an initialized map.
func (*IPv6Defragmenter) DefragIPv6 ¶
DefragIPv6 takes in an IPv6 packet with a fragment payload.
func (*IPv6Defragmenter) DefragIPv6WithTimestamp ¶
func (d *IPv6Defragmenter) DefragIPv6WithTimestamp(in *layers.IPv6, t time.Time) (*layers.IPv6, error)
DefragIPv6WithTimestamp provides functionality of DefragIPv6 with an additional timestamp parameter which is used for discarding old fragments instead of time.Now()
This is useful when operating on pcap files instead of live captured data
func (*IPv6Defragmenter) DiscardOlderThan ¶
func (d *IPv6Defragmenter) DiscardOlderThan(t time.Time) int
DiscardOlderThan forgets all packets without any activity since time t. It returns the number of FragmentList aka number of fragment packets it has discarded.
