+Subject: flow_dissect: call init_default_flow_dissectors() earlier
+
+From: Eric Dumazet <edumazet@google.com>
+
+commit c9b8af1330198ae241cd545e1f040019010d44d9 upstream.
+
+Andre Noll reported panics after my recent fix (commit 34fad54c2537
+"net: __skb_flow_dissect() must cap its return value")
+
+After some more headaches, Alexander root caused the problem to
+init_default_flow_dissectors() being called too late, in case
+a network driver like IGB is not a module and receives DHCP message
+very early.
+
+Fix is to call init_default_flow_dissectors() much earlier,
+as it is a core infrastructure and does not depend on another
+kernel service.
+
+Fixes: 06635a35d13d4 ("flow_dissect: use programable dissector in skb_flow_dissect and friends")
