Subject: [PATCH net-next 0/2] net: ipv4: remove erroneous advancement of list pointer

Tariq reported a soft lockup on net-next that Mellanox was able to
bisect to 2638eb8b50cf ("net: ipv4: provide __rcu annotation for ifa_list").

While reviewing above patch I found a regression when addresses have a
lifetime specified.

Second patch extends rtnetlink.sh to trigger crash
(without first patch applied).
