    nl80211: fix per-station group key get/del and memory leak · 0fa7b391
    Johannes Berg authored
    In case userspace attempts to obtain key information for or delete a
    unicast key, this is currently erroneously rejected unless the driver
    sets the WIPHY_FLAG_IBSS_RSN flag. Apparently enough drivers do so it
    was never noticed.
    Fix that, and while at it fix a potential memory leak: the error path
    in the get_key() function was placed after allocating a message but
    didn't free it - move it to a better place. Luckily admin permissions
    are needed to call this operation.
