       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.

      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.

      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.

      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.

      x86/mm/ptdump: Fix soft lockup in page table walker · 146fbb76
      Andrey Ryabinin authored
      CONFIG_KASAN=y needs a lot of virtual memory mapped for its shadow.
      In that case ptdump_walk_pgd_level_core() takes a lot of time to
      walk across all page tables and doing this without
      a rescheduling causes soft lockups:
      
       NMI watchdog: BUG: soft lockup - CPU#3 stuck for 23s! [swapper/0:1]
       ...
       Call Trace:
        ptdump_walk_pgd_level_core+0x40c/0x550
        ptdump_walk_pgd_level_checkwx+0x17/0x20

      I guess that this issue might arise even without KASAN on huge machines
      with several terabytes of RAM.

      x86/tsc: Make the TSC ADJUST sanitizing work for tsc_reliable · 5f2e71e7
      Thomas Gleixner authored
      When the TSC is marked reliable then the synchronization check is skipped,
      but that also skips the TSC ADJUST sanitizing code. So on a machine with a
      wreckaged BIOS the TSC deviation between CPUs might go unnoticed.
      
      Let the TSC adjust sanitizing code run unconditionally and just skip the
      expensive synchronization checks when TSC is marked reliable.

      x86/tsc: Avoid the large time jump when sanitizing TSC ADJUST · f2e04214
      Thomas Gleixner authored
      Olof reported that on a machine which has a BIOS wreckaged TSC the
      timestamps in dmesg are making a large jump because the TSC value is
      jumping forward after resetting the TSC ADJUST register to a sane value.
      
      This can be avoided by calling the TSC ADJUST saniziting function before
      initializing the per cpu sched clock machinery. That takes the offset into
      account and avoid the time jump.
      
      What cannot be avoided is that the 'Firmware Bug' warnings on the secondary
      CPUs are printed with the large time offsets because it would be too much
      effort and ugly hackery to print those warnings into a buffer and emit them
      after the adjustemt on the starting CPUs. It's a firmware bug and should be
      fixed in firmware. The weird timestamps are collateral damage and just
      illustrate the sillyness of the BIOS folks:
