Hi,

What is the status of this patch? I can not find it in Pablo's trees
(or I did not look enough).

Not having it is actually bothering me quite a lot because the vanilla
v3.18-rc2 gives the following dmesg on Fedora 21:

Oct 29 16:50:01 t440s kernel: nf_reject_ipv6: module license
'unspecified' taints kernel.
Oct 29 16:50:01 t440s kernel: Disabling lock debugging due to kernel taint
Oct 29 16:50:01 t440s kernel: nf_reject_ipv6: Unknown symbol
ip6_local_out (err 0)

And unfortunately, firewalld failed after, and I can not directly ssh
to the host.
Now that I found the solution, my process improved a lot (thank you
BTW for whoever included it in Fedora), but I guess other
distributions might hit the problem.

I would say such a trivial patch could easily go in one of the v3.18 RCs.

Cheers,
Benjamin
