The commit ab8bc7ed864b9c4f1fcb00a22bbe4e0f66ce8003 ("netfilter: remove nf_ct_is_untracked") changed the line if (ct && !nf_ct_is_untracked(ct) && nfct_nat(ct)) { to if (ct && nfct_nat(ct)) { meanwhile, the commit 41390895e50bc4f28abe384c6b35ac27464a20ec ("netfilter: ipvs: don't check for presence of nat extension") from ipvs-next had changed the same line to if (ct && !nf_ct_is_untracked(ct) && (ct->status & IPS_NAT_MASK)) { When ipvs-next got merged into nf-next, the merge resolution took the first version, dropping the conversion of nfct_nat(). While this doesn't cause a problem at the moment, it will once we stop adding the nat extension by default. Signed-off-by: Florian Westphal <fw@strlen.de> --- Pablo, I prefer if this can go via nf-next rather than ipvs-next.
