====================
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
