Sven Eckelmann 3c12d04868 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.
