Subject: linux-next: build failure after merge of the bpf-next tree

Hi all,

After merging the bpf-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

x86_64-linux-gnu-ld: net/core/filter.o: in function `sk_lookup':
(.text+0x19219): undefined reference to `__udp6_lib_lookup'

Caused by commit

6acc9b432e67 ("bpf: Add helper to retrieve socket in BPF")

I assume that __udp6_lib_lookup ended up in the IPv6 module.

I used the bpf-next tree from next-20181002 for today.

My mistake, will send out a fix shortly.
