From: Eric Dumazet <edumazet@xxxxxxxxxx>
commit 97a4d46b1516250d640c1ae0c9e7129d160d6a1c upstream.
I accidentally broke IPv4 traceroute, by swapping iph->saddr
and iph->daddr.
Probably because raw_icmp_error() and raw_v4_input()
use different order for iph->saddr and iph->daddr.
Fixes: ba44f8182ec2 ("raw: use more conventional iterators")
