Indeed, I was! Should be unsurpising.

Yeah I will admit adding the code to sock_rfree reflexively out of paranoia.

Yes, the problem appears to be in ip_vs_prepare_tunneled_skb
(ip_vs_xmit.c:859 in 4.0)
if (skb_headroom(skb) < max_headroom || skb_cloned(skb)) {
new_skb = skb_realloc_headroom(skb, max_headroom);
if (!new_skb)
goto error;
if (skb->sk)
skb_set_owner_w(new_skb, skb->sk);
consume_skb(skb);
skb = new_skb;
}
skb_set_owner_w sets sock_wfree.
I'll figure out how to ensure that we're using an appropriate destructor here.
Appreciate the patience!
