====================
net: ipv4: fix circular-list infinite loop
Tariq and Ran reported a regression caused by net-next commit
2638eb8b50cf ("net: ipv4: provide __rcu annotation for ifa_list").
This happens when net.ipv4.conf.$dev.promote_secondaries sysctl is
enabled -- we can arrange for ifa->next to point at ifa, so next
process that tries to walk the list loops forever.
Fix this and extend rtnetlink.sh with a small test case for this.
