gen_kill_estimator() / gen_new_estimator() is not always called with RTNL held. net/netfilter/xt_RATEEST.c is one user of these API that do not hold RTNL, so random corruptions can occur between "tc" and "iptables". Add a new fine grained lock instead of trying to use RTNL in netfilter. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
