-Subject: [PATCH v2] cfg80211: initialize sinfo in cfg80211_get_station
-
-Most of the implementations behind cfg80211_get_station will not initialize
-sinfo to zero before manipulating it. For example, the member "filled",
-which indicates the filled in parts of this struct, is often only modified
-by enabling certain bits in the bitfield while keeping the remaining bits
-in their original state. A caller without a preinitialized sinfo.filled can
-then no longer decide which parts of sinfo were filled in by
-cfg80211_get_station (or actually the underlying implementations).
-
-cfg80211_get_station must therefore take care that sinfo is initialized to
-zero. Otherwise, the caller may tries to read information which was not
-filled in and which must therefore also be considered uninitialized. In
-batadv_v_elp_get_throughput's case, an invalid "random" expected throughput
-may be stored for this neighbor and thus the B.A.T.M.A.N V algorithm may
-switch to non-optimal neighbors for certain destinations.
