Pablo Neira d84701ecbc netfilter: nft_counter: rework atomic dump and reset ... Dump and reset doesn't work unless cmpxchg64() is used both from packet and control plane paths. This approach is going to be slow though. Instead, use a percpu seqcount to fetch counters consistently, then subtract bytes and packets in case a reset was requested. The cpu that running over the reset code is guaranteed to own this stats exclusively, we have to turn counters into signed 64bit though so stats update on reset don't get wrong on underflow. This patch is based on original sketch from Eric Dumazet.
