Adding some debugging code reveals that net_fill_ifaddr() fails in
put_cacheinfo(skb, ifa->ifa_cstamp, ifa->ifa_tstamp,
preferred, valid))
nla_put complains:
lib/nlattr.c:454: skb_tailroom(skb) = 12, nla_total_size(attrlen) = 20
Apparently commit 5c766d642bcaffd0c2a5b354db2068515b3846cf ("ipv4:
introduce address lifetime") forgot to take into account the addition of
struct ifa_cacheinfo in inet_nlmsg_size(). Hence add it, like is already
done for ipv6.
