Subject: Re: BUG: Kernel NULL pointer dereference on write at 0x00000000 (rtmsg_ifinfo_build_skb)
Dear Paul
I don't have an IBM machine, but I tried to analyze the problem using
my x86_64 kvm virtual machine, I can't reproduce the bug using my
x86_64 kvm virtual machine.
I saw the panic is caused by registration of sit device (A sit device
is a type of virtual network device that takes our IPv6 traffic,
encapsulates/decapsulates it in IPv4 packets, and sends/receives it
over the IPv4 Internet to another host)
sit device is registered in function sit_init_net:
1895 static int __net_init sit_init_net(struct net *net)
1896 {
1897 struct sit_net *sitn = net_generic(net, sit_net_id);
1898 struct ip_tunnel *t;
1899 int err;
1900
1901 sitn->tunnels[0] = sitn->tunnels_wc;
1902 sitn->tunnels[1] = sitn->tunnels_l;
1903 sitn->tunnels[2] = sitn->tunnels_r;
1904 sitn->tunnels[3] = sitn->tunnels_r_l;
1905
1906 if (!net_has_fallback_tunnels(net))
1907 return 0;
1908
1909 sitn->fb_tunnel_dev = alloc_netdev(sizeof(struct ip_tunnel), "sit0",
1910 NET_NAME_UNKNOWN,
1911 ipip6_tunnel_setup);
1912 if (!sitn->fb_tunnel_dev) {
1913 err = -ENOMEM;
1914 goto err_alloc_dev;
1915 }
1916 dev_net_set(sitn->fb_tunnel_dev, net);
1917 sitn->fb_tunnel_dev->rtnl_link_ops = &sit_link_ops;
1918 /* FB netdevice is special: we have one, and only one per netns.
1919 * Allowing to move it to another netns is clearly unsafe.
1920 */
1921 sitn->fb_tunnel_dev->features |= NETIF_F_NETNS_LOCAL;
1922
1923 err = register_netdev(sitn->fb_tunnel_dev);
register_netdev on line 1923 will call if_nlmsg_size indirectly.
On the other hand, the function that calls the paniced strlen is if_nlmsg_size:
(gdb) disassemble if_nlmsg_size
Dump of assembler code for function if_nlmsg_size:
0xffffffff81a0dc20 <+0>: nopl 0x0(%rax,%rax,1)
0xffffffff81a0dc25 <+5>: push %rbp
0xffffffff81a0dc26 <+6>: push %r15
0xffffffff81a0dd04 <+228>: je 0xffffffff81a0de20 <if_nlmsg_size+512>
0xffffffff81a0dd0a <+234>: mov 0x10(%rbp),%rdi
...
=> 0xffffffff81a0dd0e <+238>: callq 0xffffffff817532d0 <strlen>
0xffffffff81a0dd13 <+243>: add $0x10,%eax
0xffffffff81a0dd16 <+246>: movslq %eax,%r12
and the C code for 0xffffffff81a0dd0e is following (line 524):
515 static size_t rtnl_link_get_size(const struct net_device *dev)
516 {
517 const struct rtnl_link_ops *ops = dev->rtnl_link_ops;
518 size_t size;
519
520 if (!ops)
521 return 0;
522
523 size = nla_total_size(sizeof(struct nlattr)) + /* IFLA_LINKINFO */
524 nla_total_size(strlen(ops->kind) + 1); /* IFLA_INFO_KIND */
But ops is assigned the value of sit_link_ops in function sit_init_net
line 1917, so I guess something must happened between the calls.
Do we have KASAN in IBM machine? would KASAN help us find out what
happened in between?
Hope I can be of more helpful.
Thanks
Sincerely
Zhouyi
