iptables audit target causes kernel panic with iptables-persistent (kernel 3.2.78)

[Lev Stipakov]

Hello,

I see kernel panic with iptables-persistent package installed and one 
iptables rule with AUDIT target.

   root at debian7:~# uname -a
   Linux debian7 3.2.0-4-amd64 #1 SMP Debian 3.2.78-1 x86_64 GNU/Linux

   root at debian7:~# dpkg -l | grep iptables
   ii  iptables			1.4.14-3.1
   ii  iptables-persistent	0.5.7+deb7u1

Steps to reproduce:

1) Install Debian 7 and iptables-persistent (see versions above)
2) Add iptables rule (must be OUTPUT chain):

   root at debian7:~# iptables -I OUTPUT -j AUDIT --type ACCEPT

3) Save rule:

   root at debian7:~# iptables-save > /etc/iptables/rules.v4

4) Reboot

5) Kernel panic (screenshot):

I cannot reproduce it on (one of) previous kernel version:

   lev at debi7:~$ uname -a
   Linux debi7 3.2.0-4-amd64 #1 SMP Debian 3.2.73-2+deb7u2 x86_64 GNU/Linux

   lev at debi7:~$ dpkg -l | grep iptables
   ii  iptables                           1.4.14-3.1
   ii  iptables-persistent                0.5.7+deb7u1
