Hi David,
There are new compile warnings show up in
tree: git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git master
head: 3ec5a261aef55a32664bffd335e5c32aeadf3215
commit: e47a185b31dd2acd424fac7dc0efb96fc5b31a33 [90/102] ipv4: Generalize ip_do_redirect() and hook into new dst_ops->redirect.
All warnings:
net/ipv4/route.c: In function 'ip_do_redirect':
net/ipv4/route.c:1283:9: warning: unused variable 'saddr' [-Wunused-variable]
net/ipv4/route.c:1282:9: warning: unused variable 'daddr' [-Wunused-variable]
vim +1283 net/ipv4/route.c
1280 __be32 old_gw = ip_hdr(skb)->saddr;
1281 struct net_device *dev = skb->dev;
1282 __be32 daddr = iph->daddr;
> 1283 __be32 saddr = iph->saddr;
1284 struct in_device *in_dev;
1285 struct neighbour *n;
1286 struct rtable *rt;
..because the saddr/daddr variables are used inside
#ifdef CONFIG_IP_ROUTE_VERBOSE
if (IN_DEV_LOG_MARTIANS(in_dev))
net_info_ratelimited("Redirect from %pI4 on %s about %pI4 ignored\n"
" Advised path = %pI4 -> %pI4\n",
&old_gw, dev->name, &new_gw,
&saddr, &daddr);
#endif
