Functions

func Hash3Words

func Hash3Words(a, b, c, initval uint32) uint32

Hash3Words calculates the Jenkins hash of 3 32-bit words. This is adapted from linux.

func IPv4FragmentHash

func IPv4FragmentHash(h header.IPv4) uint32

IPv4FragmentHash computes the hash of the IPv4 fragment as suggested in RFC 791.

func IPv6FragmentHash

func IPv6FragmentHash(h header.IPv6, f header.IPv6Fragment) uint32

IPv6FragmentHash computes the hash of the ipv6 fragment. Unlike IPv4, the protocol is not used to compute the hash. RFC 2640 (sec 4.5) is not very sharp on this aspect. As a reference, also Linux ignores the protocol to compute the hash (inet6_hash_frag).

func RandN32

func RandN32(n int) []uint32

RandN32 generates a slice of n cryptographic random 32-bit numbers.
