      net: enable usercopy for skb_small_head_cache · 0b34d680
      Eric Dumazet authored
      syzbot and other bots reported that we have to enable
      user copy to/from skb->head. [1]
      
      We can prevent access to skb_shared_info, which is a nice
      improvement over standard kmem_cache.
      
      Layout of these kmem_cache objects is:
      
      < SKB_SMALL_HEAD_HEADROOM >< struct skb_shared_info >
      
      usercopy: Kernel memory overwrite attempt detected to SLUB object 'skbuff_small_head' (offset 32, size 20)!

      The PGID_MCIPV6 is configured correctly to not flood to the CPU,
      I checked that.
      
      Furthermore, when I disable back PTP RX timestamping (ptp4l doesn't do
      that when it exists), packets are RX filtered again as they should be:

      So it's clear that something in the PTP RX trapping logic went wrong.
      
      Looking a bit at the code, I can see that there are 4 typos, which
      populate "ipv4" VCAP IS2 key filter fields for IPv6 keys.
      
      VCAP IS2 keys of type OCELOT_VCAP_KEY_IPV4 and OCELOT_VCAP_KEY_IPV6 are
      handled by is2_entry_set(). OCELOT_VCAP_KEY_IPV4 looks at
      &filter->key.ipv4, and OCELOT_VCAP_KEY_IPV6 at &filter->key.ipv6.
      Simply put, when we populate the wrong key field, &filter->key.ipv6
      fields "proto.mask" and "proto.value" remain all zeroes (or "don't care").
      So is2_entry_set() will enter the "else" of this "if" condition:
      
      	if (msk == 0xff && (val == IPPROTO_TCP || val == IPPROTO_UDP))
      
      and proceed to ignore the "proto" field. The resulting rule will match
      on all IPv6 traffic, trapping it to the CPU.
      
      This is the reason why the local_termination.sh selftest sees it,
      because control traps are stronger than the PGID_MCIPV6 used for
      flooding (from the forwarding data path).
      
      But the problem is in fact much deeper. We trap all IPv6 traffic to the
      CPU, but if we're bridged, we set skb->offload_fwd_mark = 1, so software
      forwarding will not take place and IPv6 traffic will never reach its
      destination.
      
      The fix is simple - correct the typos.
      
      I was intentionally inaccurate in the commit message about the breakage
      occurring when any PTP timestamping is enabled. In fact it only happens
      when L4 timestamping is requested (HWTSTAMP_FILTER_PTP_V2_EVENT or
      HWTSTAMP_FILTER_PTP_V2_L4_EVENT). But ptp4l requests a larger RX
      timestamping filter than it needs for "-2": HWTSTAMP_FILTER_PTP_V2_EVENT.
      I wanted people skimming through git logs to not think that the bug
      doesn't affect them because they only use ptp4l in L2 mode.

      RDMA/mlx5: Track netdev to avoid deadlock during netdev notifier unregister · dca55da0
      Jiri Pirko authored
      When removing a network namespace with mlx5 devlink instance being in
      it, following callchain is performed:
      
      cleanup_net (takes down_read(&pernet_ops_rwsem)
      devlink_pernet_pre_exit()
      devlink_reload()
      mlx5_devlink_reload_down()
      mlx5_unload_one_devl_locked()
      mlx5_detach_device()
      del_adev()
      mlx5r_remove()
      __mlx5_ib_remove()
      mlx5_ib_roce_cleanup()
      mlx5_remove_netdev_notifier()
      unregister_netdevice_notifier (takes down_write(&pernet_ops_rwsem)
      
      This deadlocks.
      
      Resolve this by converting to register_netdevice_notifier_dev_net()
      which does not take pernet_ops_rwsem and moves the notifier block around
      according to netdev it takes as arg.
      
      Use previously introduced netdev added/removed events to track uplink
      netdev to be used for register_netdevice_notifier_dev_net() purposes.

      Move the set() helper to core.c from header, introduce clear() and
      netdev_added_event_replay() helpers. The last one is going to be called
