From c9b8af1330198ae241cd545e1f040019010d44d9 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Tue, 22 Nov 2016 11:17:30 -0800 Subject: [PATCH] flow_dissect: call init_default_flow_dissectors() earlier 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.
