        certain ARM IOMMU configurations, a stack data leak for hfi1, and
        various testing discovered -rc bug fixes for i40iw.

      arch/tile: mark as orphaned · 8ee5ad1d
      Chris Metcalf authored
      The chip family of TILEPro and TILE-Gx was developed by Tilera, which
      was eventually acquired by Mellanox.  The tile architecture was added to
      the kernel in 2010 and first appeared in 2.6.36.
      Now at Mellanox we are developing new chips based on the ARM64
      architecture; our last TILE-Gx chip (the Gx72) was released in 2013, and
      our customers using tile architecture products are not, as far as we
      know, looking to upgrade to newer kernel releases.  In the absence of
      someone in the community stepping up to take over maintainership, this
      commit marks the architecture as orphaned.

      pull-request: bpf 2017-12-02
      The following pull-request contains BPF updates for your *net* tree.
      The main changes are:
      1) Fix a compilation warning in xdp redirect tracepoint due to
         missing bpf.h include that pulls in struct bpf_map, from Xie.
      2) Limit the maximum number of attachable BPF progs for a given
         perf event as long as uabi is not frozen yet. The hard upper
         limit is now 64 and therefore the same as with BPF multi-prog
         for cgroups. Also add related error checking for the sample
         BPF loader when enabling and attaching to the perf event, from
      3) Specifically set the RLIMIT_MEMLOCK for the test_verifier_log
         case, so that the test case can always pass and not fail in
         some environments due to too low default limit, also from
      4) Fix up a missing license header comment for kernel/bpf/offload.c,
         from Jakub.
      5) Several fixes for bpftool, among others a crash on incorrect
         arguments when json output is used, error message handling
         fixes on unknown options and proper destruction of json writer
         for some exit cases, all from Quentin.

      Eric Dumazet authored
      James Morris reported kernel stack corruption bug [1] while
      running the SELinux testsuite, and bisected to a recent
      commit bffa72cf ("net: sk_buff rbnode reorg")
      We believe this commit is fine, but exposes an older bug.
      SELinux code runs from tcp_filter() and might send an ICMP,
      expecting IP options to be found in skb->cb[] using regular IPCB placement.
      We need to defer TCP mangling of skb->cb[] after tcp_filter() calls.
      This patch adds tcp_v4_fill_cb()/tcp_v4_restore_cb() in a very
      similar way we added them for IPv6.

      stmmac: reset last TSO segment size after device open · 45ab4b13
      Lars Persson authored
      The mss variable tracks the last max segment size sent to the TSO
      engine. We do not update the hardware as long as we receive skb:s with
      the same value in gso_size.
      During a network device down/up cycle (mapped to stmmac_release() and
      stmmac_open() callbacks) we issue a reset to the hardware and it
      forgets the setting for mss. However we did not zero out our mss
      variable so the next transmission of a gso packet happens with an
      undefined hardware setting.
      This triggers a hang in the TSO engine and eventuelly the netdev
      watchdog will bark.

      Julian Wiedmann authored
      The current GSO skb size limit was copy&pasted over from the L3 path,
      where it is needed due to a TSO limitation.
      As L2 devices don't offer TSO support (and thus all GSO skbs are
      segmented before they reach the driver), there's no reason to restrict
      the stack in how large it may build the GSO skbs.

      s390/qeth: fix GSO throughput regression · 6d69b1f1
      Julian Wiedmann authored
      Using GSO with small MTUs currently results in a substantial throughput
      regression - which is caused by how qeth needs to map non-linear skbs
      into its IO buffer elements:
      compared to a linear skb, each GSO-segmented skb effectively consumes
      twice as many buffer elements (ie two instead of one) due to the
      additional header-only part. This causes the Output Queue to be
      congested with low-utilized IO buffers.
      Fix this as follows:
      If the MSS is low enough so that a non-SG GSO segmentation produces
      order-0 skbs (currently ~3500 byte), opt out from NETIF_F_SG. This is
      where we anticipate the biggest savings, since an SG-enabled
      GSO segmentation produces skbs that always consume at least two
      buffer elements.
      Larger MSS values continue to get a SG-enabled GSO segmentation, since
      1) the relative overhead of the additional header-only buffer element
      becomes less noticeable, and
      2) the linearization overhead increases.
      With the throughput regression fixed, re-enable NETIF_F_SG by default to
      reap the significant CPU savings of GSO.

      s390/qeth: fix thinko in IPv4 multicast address tracking · bc3ab705
      Julian Wiedmann authored
      Commit 5f78e29c ("qeth: optimize IP handling in rx_mode callback")
      reworked how secondary addresses are managed for qeth devices.
      Instead of dropping & subsequently re-adding all addresses on every
      ndo_set_rx_mode() call, qeth now keeps track of the addresses that are
      currently registered with the HW.
      On a ndo_set_rx_mode(), we thus only need to do (de-)registration
      requests for the addresses that have actually changed.
      On L3 devices, the lookup for IPv4 Multicast addresses checks the wrong
      hashtable - and thus never finds a match. As a result, we first delete
      *all* such addresses, and then re-add them again. So each set_rx_mode()
      causes a short period where the IPv4 Multicast addresses are not
      registered, and the card stops forwarding inbound traffic for them.
      Fix this by setting the ->is_multicast flag on the lookup object, thus
      enabling qeth_l3_ip_from_hash() to search the correct hashtable and
      find a match there.
