      ====================
      During the Wireless Battle Mesh v9 in Porto (PT) at the beginning of
      May, we managed to uncover and fix some important bugs in our
      new B.A.T.M.A.N. V algorithm. These are the fixes we came up with
      together with others that I collected in the past weeks:
      - avoid potential crash due to NULL pointer dereference in
        B.A.T.M.A.N. V routine when a neigh_ifinfo object is not found, by
        Sven Eckelmann
      - avoid use-after-free of skb when counting outgoing bytes, by Florian
        Westphal
      - fix neigh_ifinfo object reference counting imbalance when using
        B.A.T.M.A.N. V, by Sven Eckelmann. Such imbalance may lead to the
        impossibility of releasing the related netdev object on shutdown
      - avoid invalid memory access in case of error while allocating
        bcast_own_sum when a new hard-interface is added, by Sven Eckelmann
      - ensure originator address is updated in OMG/ELP packet content upon
        primary interface address change, by Antonio Quartulli
      - fix integer overflow when computing TQ metric (B.A.T.M.A.N. IV), by
        Sven Eckelmann
      - avoid race condition while adding new neigh_node which would result
        in having two objects mapping to the same physical neighbour, by
        Linus Lüssing
      - ensure originator address is initialized in ELP packet content on
        secondary interfaces, by Marek Lindner

      ====================
      net: block BH in TCP callbacks
      
      Four layers using TCP stack were assuming sk_callback_lock could
      be locked using read_lock() in their handlers because TCP stack
      was running with BH disabled.
      
      This is no longer the case. Since presumably the rest could
      also depend on BH being disabled, just use read_lock_bh().
      
      Then each layer might consider switching to RCU protection
      and no longer depend on BH.

      tipc: block BH in TCP callbacks · b91083a4
      Eric Dumazet authored
      TCP stack can now run from process context.
      
      Use read_lock_bh(&sk->sk_callback_lock) variant to restore previous
      assumption.
      
      Fixes: 5413d1ba ("net: do not block BH while processing socket backlog")
