How do I convert:
addr = *(__be32 *)(skb->nh.raw + serr->addr_offset);
to use the ICMP accessor macros now that skb->nh is no longer available? I
was using this to pluck an address out of the ICMP packet payload, but
void rxrpc_UDP_error_report(struct sock *sk)
{
struct sock_exterr_skb *serr;
...
struct sk_buff *skb;
__be32 addr;
__be16 port;
...
skb = skb_dequeue(&sk->sk_error_queue);
if (!skb) {
_leave("UDP socket errqueue empty");
return;
}
...
serr = SKB_EXT_ERR(skb);
addr = *(__be32 *)(skb->nh.raw + serr->addr_offset);
port = serr->port;
_net("Rx UDP Error from "NIPQUAD_FMT":%hu",
NIPQUAD(addr), ntohs(port));
...
}
Should I do this?:
addr = *(__be32 *)(skb_network_header(skb) + serr->addr_offset);
