[NETNS]: The ip6_fib_timer can work with garbage on net namespace stop.
The del_timer() function doesn't guarantee, that the timer callback is not active by the time it exits. Thus, the fib6_net_exit() may kfree() all the data, that is required by the fib6_run_gc(). The race window is tiny, but slab poisoning can trigger this bug. Using del_timer_sync() will cure this. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.
