Affected: Linux

In the Linux kernel, the following vulnerability has been resolved:

pfcp: Destroy device along with udp socket's netns dismantle.

pfcp_newlink() links the device to a list in dev_net(dev) instead of net, where a udp tunnel socket is created.

Even when net is removed, the device stays alive on dev_net(dev). Then, removing net triggers the splat below. [0]

In this example, pfcp0 is created in ns2, but the udp socket is created in ns1.

ip netns add ns1 ip netns add ns2 ip -n ns1 link add netns ns2 name pfcp0 type pfcp ip netns del ns1

Let's link the device to the socket's netns instead.

Now, pfcp_net_exit() needs another netdev iteration to remove all pfcp devices in the netns.

pfcp_dev_list is not used under RCU, so the list API is converted to the non-RCU variant.

pfcp_net_exit() can be converted to .exit_batch_rtnl() in net-next.
