Florian Westphal 04f9e9104c netfilter: conntrack: re-fetch conntrack after insertion ... commit 56b14ecec9 upstream. In case the conntrack is clashing, insertion can free skb->_nfct and set skb->_nfct to the already-confirmed entry. This wasn't found before because the conntrack entry and the extension space used to free'd after an rcu grace period, plus the race needs events enabled to trigger.
