Strangely I don't see this error with gcc 7.3
I've tried this patch and it doesn't hurt,
but before it gets applied could you please try
the top two patches from this tree:
https://git.kernel.org/pub/scm/linux/kernel/git/ast/bpf.git/?h=ipt_bpf
in your environment?
These two patches add the actual meat of bpfilter and I'd like
to make sure the build setup is good for everyone before
we proceed too far.
