Title:
  Kernel panic on 3.8.0-29 when using ipvs

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Raring:
  Fix Released
Status in “linux” source package in Saucy:
  Fix Released

Bug description:
  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.

  ---

  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,
  Luc van Donkersgoed
