Merge tag 'net-7.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

Pull networking fixes from Paolo Abeni:
 "Including fixes from IPsec and netfilter.

  This is relatively small, mostly because we are a bit behind our PW
  queue. I'm not aware of any pending regression.

  Current release - regressions:

   - netfilter: nf_tables_offload: drop device refcount on error

  Previous releases - regressions:

   - core: add pskb_may_pull() to skb_gro_receive_list()

   - xfrm: iptfs: preserve shared-frag marker in iptfs_consume_frags()

   - ipv6: fix a potential NPD in cleanup_prefix_route()

   - ipv4: fix use-after-free caused by the fqdir_pre_exit() flush

   - eth:
      - bnxt_en: fix NULL pointer dereference
      - emac: fix use-after-free during device removal
      - octeontx2-af: fix memory leak in rvu_setup_hw_resources()
      - tun: zero the whole vnet header in tun_put_user()
      - sit: reload inner IPv6 header after GSO offloads

  Previous releases - always broken:

   - core: fix double-free in netdev_nl_bind_rx_doit()

   - netfilter: nf_log: validate MAC header was set before dumping it

   - xfrm: iptfs: fix ABBA deadlock in iptfs_destroy_state()

   - tcp: restrict SO_ATTACH_FILTER to priv users

   - mctp: usb: fix race between urb completion and rx_retry
     cancellation

   - eth:
      - mlx5: fix slab-out-of-bounds in mlx5_query_nic_vport_mac_list
      - mvpp2: sync RX data at the hardware packet offset"
