Linux 4.6: VRF clarification for egress Broadcast Pk

[Sukumar Gopalakrishnan]

Hi,

VRF egress processing routine does not process multicast packet but
broadcast packet is not diverted.  I added code changes  to not to
process broadcast packet by the VRF driver.. Is my assumption correct
?



static struct sk_buff *vrf_ip_out(struct net_device *vrf_dev, struct
sock *sk, struct sk_buff *skb) {

/* don’t divert multicast */
if (ipv4_is_multicast(ip_hdr(skb)->daddr))
return skb;

…
/* don’t divert broadcast */
if (ipv4_is_lbcast(ip_hdr(skb)->daddr)) { return skb;



Regards,

Sukumar
