In kernel 3.8.0-29 and higher (I've tested 3.8.0-30 and 3.8.0-31), the kernel panics when adding IPVS service. Specifically, when I execute the following command:
sudo ipvsadm -A -u 10.0.50.4:53
The kernel immediately panics. I've reverted the kernel to 3.8.0-27, and IPVS executes without a problem.
The panic is completely reproducable, using a clean install, no extra packages installed, all packages upgraded.
I've attached the apport report of the system running 3.8.0-29.
Best,

SRU Justification:
Impact:
A NULL pointer dereferrence will occur when a user adds an IPVS service. This occurs since kernel 3.8.0-28.41 (Raring), after commit:
dc7b3eb ipvs: Fix reuse connection if real server is dead
The NULL pointer occurs when accessing the ipvs variable in line 1658:
1658 if (unlikely(sysctl_expire_nodest_conn(ipvs)) && cp && cp->dest &&
1659 unlikely(!atomic_read(&cp->dest->weight)) && !iph.fragoffs &&
1660 is_new_conn(skb, &iph)) {
1661 ip_vs_conn_expire_now(cp);
1662 __ip_vs_conn_put(cp);
1663 cp = NULL;
1664 }
Mainline kernel has this variable initialised earlier, with commit:
0c12582 ipvs: add backup_only flag to avoid loops
Fix:
Apply commit 0c12582 "ipvs: add backup_only flag to avoid loops" fix the problem. Bug reporter has claimed success with a test kernel that contains this commit.
Testcase:
Simply running the command:
sudo ipvsadm -A -u 10.0.50.4:53
Will trigger the bug.
