      netpoll: Check for skb->queue_mapping · c70b17b7
      Tushar Dave authored
      Reducing real_num_tx_queues needs to be in sync with skb queue_mapping
      otherwise skbs with queue_mapping greater than real_num_tx_queues
      can be sent to the underlying driver and can result in kernel panic.
      
      One such event is running netconsole and enabling VF on the same
      device. Or running netconsole and changing number of tx queues via
      ethtool on same device.
      
      e.g.
      Unable to handle kernel NULL pointer dereference
      tsk->{mm,active_mm}->context = 0000000000001525

      ip6mr: fix notification device destruction · 723b929c
      Nikolay Aleksandrov authored
      Andrey Konovalov reported a BUG caused by the ip6mr code which is caused
      because we call unregister_netdevice_many for a device that is already
      being destroyed. In IPv4's ipmr that has been resolved by two commits
      long time ago by introducing the "notify" parameter to the delete
      function and avoiding the unregister when called from a notifier, so
      let's do the same for ip6mr.
      
      The trace from Andrey:

      bpf: Fix values type used in test_maps · 89087c45
      David Miller authored
      Maps of per-cpu type have their value element size adjusted to 8 if it
      is specified smaller during various map operations.
      
      This makes test_maps as a 32-bit binary fail, in fact the kernel
      writes past the end of the value's array on the user's stack.
      
      To be quite honest, I think the kernel should reject creation of a
      per-cpu map that doesn't have a value size of at least 8 if that's
      what the kernel is going to silently adjust to later.
      
      If the user passed something smaller, it is a sizeof() calcualtion
      based upon the type they will actually use (just like in this testcase
      code) in later calls to the map operations.

      Andrey's syzkaller program passes rtmsg.rtmsg_flags with the RTF_PCPU bit
      set. Flags passed to the kernel are blindly copied to the allocated
      rt6_info by ip6_route_info_create making a newly inserted route appear
      as though it is a per-cpu route. ip6_rt_cache_alloc sees the flag set
      and expects rt->dst.from to be set - which it is not since it is not
      really a per-cpu copy. The subsequent call to __ip6_dst_alloc then
      generates the fault.
      
      Fix by checking for the flag and failing with EINVAL.

      gso: Validate assumption of frag_list segementation · 43170c4e
      Ilan Tayari authored
      Commit 07b26c94 ("gso: Support partial splitting at the frag_list
      pointer") assumes that all SKBs in a frag_list (except maybe the last
      one) contain the same amount of GSO payload.
      
      This assumption is not always correct, resulting in the following
      warning message in the log:
          skb_segment: too many frags
      
      For example, mlx5 driver in Striding RQ mode creates some RX SKBs with
      one frag, and some with 2 frags.
      After GRO, the frag_list SKBs end up having different amounts of payload.
      If this frag_list SKB is then forwarded, the aforementioned assumption
      is violated.
      
      Validate the assumption, and fall back to software GSO if it not true.

      Eric Dumazet authored
      We can use skb_cow_head() to properly deal with clones,
      especially the ones coming from TCP stack that allow their head being
      modified. This avoids a copy.

       "A couple of last minute fixes for regressions in this cycle. More
        specifically:
      
         - Two patches from Andy, adjusting the NVMe APST quirks to avoid some
           issues specific to one Toshiba drive, and some variant of Samsung
           on two specific Dell laptops.
      
         - A fix for mtip32xx, turning off mq scheduling on that device. We
           have a real fix for this, but it's too late in the cycle.
           Thankfully we already have a NO_SCHED flag we can apply here. A
           prep patch for this is ensuring that we honor the NO_SCHED flag
           when attempting to online switch schedulers, previsouly we only did
           so for drive load time. From Ming.
      
         - Fixing an oops in blk-mq polling with scheduling attached. This one
           is easily reproducible, it would be a shame to release 4.11 with
           that issue. From me.
      
        I'd prefer not having to send in patches at this point in time, but
        the above are all things that have regressed in this cycle and the
        fixes are relatively straight forward"
