Eric Dumazet d199fab63c packet: fix races in fanout_add() ... Multiple threads can call fanout_add() at the same time. We need to grab fanout_mutex earlier to avoid races that could lead to one thread freeing po->rollover that was set by another thread. Do the same in fanout_release(), for peace of mind, and to help us finding lockdep issues earlier. Fixes: dc99f60069 ("packet: Add fanout support.") Fixes: 0648ab70af ("packet: rollover prepare: per-socket state") Signed-off-by: Eric Dumazet <edumazet@google.com> Cc: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.
