       1) If the timing is wrong we can indefinitely stop generating new ipv6
          temporary addresses, from Marcus Huewe.
      
       2) Don't double free per-cpu stats in ipv6 SIT tunnel driver, from Cong
          Wang.
      
       3) Put protections in place so that AF_PACKET is not able to submit
          packets which don't even have a link level header to drivers. From
          Willem de Bruijn.
      
       4) Fix memory leaks in ipv4 and ipv6 multicast code, from Hangbin Liu.
      
       5) Don't use udp_ioctl() in l2tp code, UDP version expects a UDP socket
          and that doesn't go over very well when it is passed an L2TP one.
          Fix from Eric Dumazet.
      
       6) Don't crash on NULL pointer in phy_attach_direct(), from Florian
          Fainelli.

      l2tp: do not use udp_ioctl() · 72fb96e7
      Eric Dumazet authored
      udp_ioctl(), as its name suggests, is used by UDP protocols,
      but is also used by L2TP :(
      
      L2TP should use its own handler, because it really does not
      look the same.
      
      SIOCINQ for instance should not assume UDP checksum or headers.
      
      Thanks to Andrey and syzkaller team for providing the report
      and a nice reproducer.
      
      While crashes only happen on recent kernels (after commit
      7c13f97f ("udp: do fwd memory scheduling on dequeue")), this
      probably needs to be backported to older kernels.
      
      Fixes: 7c13f97f ("udp: do fwd memory scheduling on dequeue")
      Fixes: 85584672 ("udp: Fix udp_poll() and ioctl()")

      xen-netfront: Delete rx_refill_timer in xennet_disconnect_backend() · 74470954
      Boris Ostrovsky authored
      rx_refill_timer should be deleted as soon as we disconnect from the
      backend since otherwise it is possible for the timer to go off before
      we get to xennet_destroy_queues(). If this happens we may dereference
      queue->rx.sring which is set to NULL in xennet_disconnect_backend().

      NET: mkiss: Fix panic · 7ba1b689
      Ralf Baechle authored
      If a USB-to-serial adapter is unplugged, the driver re-initializes, with
      dev->hard_header_len and dev->addr_len set to zero, instead of the correct
      values.  If then a packet is sent through the half-dead interface, the
      kernel will panic due to running out of headroom in the skb when pushing
      for the AX.25 headers resulting in this panic:
      
      [<c0595468>] (skb_panic) from [<c0401f70>] (skb_push+0x4c/0x50)
      [<c0401f70>] (skb_push) from [<bf0bdad4>] (ax25_hard_header+0x34/0xf4 [ax25])
      [<bf0bdad4>] (ax25_hard_header [ax25]) from [<bf0d05d4>] (ax_header+0x38/0x40 [mkiss])
      [<bf0d05d4>] (ax_header [mkiss]) from [<c041b584>] (neigh_compat_output+0x8c/0xd8)
      [<c041b584>] (neigh_compat_output) from [<c043e7a8>] (ip_finish_output+0x2a0/0x914)
      [<c043e7a8>] (ip_finish_output) from [<c043f948>] (ip_output+0xd8/0xf0)
      [<c043f948>] (ip_output) from [<c043f04c>] (ip_local_out_sk+0x44/0x48)
      
      This patch makes mkiss behave like the 6pack driver. 6pack does not
      panic.  In 6pack.c sp_setup() (same function name here) the values for
      dev->hard_header_len and dev->addr_len are set to the same values as in
      my mkiss patch.

      net: hns: Fix the device being used for dma mapping during TX · b85ea006
      Kejian Yan authored
      This patch fixes the device being used to DMA map skb->data.
      Erroneous device assignment causes the crash when SMMU is enabled.
      This happens during TX since buffer gets DMA mapped with device
      correspondign to net_device and gets unmapped using the device
      related to DSAF.

      This patch incorrectly attempted nested mnt_want_write, and incorrectly

      and make another attempt soon, for the moment I think the safest is to
