Jiri Pirko ab5b526da0 net: genetlink: always allocate separate attrs for dumpit ops ... Individual dumpit ops (start, dumpit, done) are locked by genl_lock if !family->parallel_ops. However, multiple genl_family_rcv_msg_dumpit() calls may in in flight in parallel. Each has a separate struct genl_dumpit_info allocated but they share the same family->attrbuf. Fix this by allocating separate memory for attrs for dumpit ops, for non-parallel_ops (for parallel_ops it is done already).
