Functions

func DiffFromCIDRs

func DiffFromCIDRs(allowCIDR *net.IPNet, exceptCIDRs []*net.IPNet) ([]*net.IPNet, error)

This function takes in one allow CIDR and multiple except CIDRs and gives diff CIDRs in allowCIDR eliminating except CIDRs. It currently supports only IPv4. except CIDR input can be changed.

func IPNetToNetIPNet

func IPNetToNetIPNet(ipNet *v1beta2.IPNet) *net.IPNet

IPNetToNetIPNet converts Antrea IPNet to *net.IPNet. Note that K8s allows non-standard CIDRs to be specified (e.g. 10.0.1.1/16, fe80::7015:efff:fe9a:146b/64). However, OVS will report OFPBMC_BAD_WILDCARDS error if using them in the OpenFlow messages. The function will normalize the CIDR if it's non-standard.
