Summary0000865: CONFIG_NET_FOU_IP_TUNNELS is required to create fou ipip tunnel.
DescriptionPlease enable CONFIG_NET_FOU_IP_TUNNELS kernel config.
It's required to use fou ipip tunnel.

To verify:

sudo ip link add 1 type ipip local 1.1.1.1 remote 2.2.2.2 encap fou encap-sport 5353 encap-dport 6464


On Fedora, once `modprobe fou`. Command works.
On kernel-ml, Got `RTNETLINK answers: Invalid argument`.

Acknowledged.

Looking at the master configuration files for kernel-{lt|ml} we see --

[kernels]$ grep -r CONFIG_NET_FOU_IP_TUNNELS * | grep -E '4\.4\.150|4\.18\.3' | sort
el6/config-4.18/config-4.18.3-i686:# CONFIG_NET_FOU_IP_TUNNELS is not set

I have now queued the requested configuration adjustment, CONFIG_NET_FOU_IP_TUNNELS=y, for the next builds of the kernel-{lt|ml} package sets, for both EL6 and EL7.

I have manually compile the kernel-ml-4.18.3-1 with `CONFIG_NET_FOU_IP_TUNNELS=y`. The Foo Over UDP works quite well now.

FYI.

The recently released kernel-ml-4.18.4-1.el7.elrepo package set [1] has the CONFIG_NET_FOU_IP_TUNNELS option enabled.

Now closing as "resolved/fixed".
