      net/macb: Factor out one-time assignment from loop · 21d3515c
      Ben Shelton authored
      In 02c958dd (net/macb: add TX multiqueue support for gem), the
      initialization of tx_head and tx_tail in macb_init_rings() was moved
      inside the loop that iterates over each element in the ring.  Since
      tx_head and tx_tail only need to be assigned once, move them back out of
      the loop.

      net: do not deplete pfmemalloc reserve · 79930f58
      Eric Dumazet authored
      build_skb() should look at the page pfmemalloc status.
      If set, this means page allocator allocated this page in the
      expectation it would help to free other pages. Networking
      stack can do that only if skb->pfmemalloc is also set.
      
      Also, we must refrain using high order pages from the pfmemalloc
      reserve, so __page_frag_refill() must also use __GFP_NOMEMALLOC for
      them. Under memory pressure, using order-0 pages is probably the best
      strategy.

      ====================
      mpls: ABI changes for security and correctness
      
      V2:
       - don't treat loopback interfaces specially by enabling mpls by
         default
      
      These changes make mpls not be enabled by default on all
      interfaces when in use for security, along with ensuring that a label
      not valid as an outgoing label can be added in mpls routes.
      
      This series contains three ABI/behaviour-affecting changes which have
      been split out from "[PATCH net-next v4 0/6] mpls: Behaviour-changing
      improvements" without any further modification. These changes need to
      be considered for 4.1 otherwise we'll be stuck with the current
      behaviour/ABI forever.

      mpls: Per-device enabling of packet input · 37bde799
      Robert Shearman authored
      An MPLS network is a single trust domain where the edges must be in
      control of what labels make their way into the core. The simplest way
      of ensuring this is for the edge device to always impose the labels,
      and not allow forward labeled traffic from untrusted neighbours. This
      is achieved by allowing a per-device configuration of whether MPLS
      traffic input from that interface should be processed or not.
      
      To be secure by default, the default state is changed to MPLS being
      disabled on all interfaces unless explicitly enabled and no global
      option is provided to change the default. Whilst this differs from
      other protocols (e.g. IPv6), network operators are used to explicitly
      enabling MPLS forwarding on interfaces, and with the number of links
      to the MPLS core typically fairly low this doesn't present too much of
      a burden on operators.

      Add per-device MPLS state to supported interfaces. Use the presence of

      bnx2x: Prevent inner-reload while VFs exist · 909d9faa
      Yuval Mintz authored
      On some feature changes, driver employes an inner-reload flow where it
      resets the function and re-configures it with the new required set of
      parameters.
      
      Such a flow proves fatal to any VF since those were not intended to be used
      while HW is being reset underneath, causing them [at best] to lose all
      connectivity.
      
      This changes driver behavior to fail all configuration changes [e.g., mtu
      change] requested of the driver in case VFs are active.

      rhashtable: Do not schedule more than one rehash if we can't grow further · a87b9ebf
      Thomas Graf authored
      The current code currently only stops inserting rehashes into the
      chain when no resizes are currently scheduled. As long as resizes
      are scheduled and while inserting above the utilization watermark,
      more and more rehashes will be scheduled.
      
      This lead to a perfect DoS storm with thousands of rehashes
      scheduled which lead to thousands of spinlocks to be taken
      sequentially.
      
      Instead, only allow either a series of resizes or a single rehash.
      Drop any further rehashes and return -EBUSY.

      rhashtable: Schedule async resize when sync realloc fails · e2307ed6
      Thomas Graf authored
      When rhashtable_insert_rehash() fails with ENOMEM, this indicates that
      we can't allocate the necessary memory in the current context but the
      limits as set by the user would still allow to grow.
      
      Thus attempt an async resize in the background where we can allocate
      using GFP_KERNEL which is more likely to succeed. The insertion itself
      will still fail to indicate pressure.
      
      This fixes a bug where the table would never continue growing once the
      utilization is above 100%.

      tcp: fix possible deadlock in tcp_send_fin() · d83769a5
      Eric Dumazet authored
      Using sk_stream_alloc_skb() in tcp_send_fin() is dangerous in
      case a huge process is killed by OOM, and tcp_mem[2] is hit.
      
      To be able to free memory we need to make progress, so this
      patch allows FIN packets to not care about tcp_mem[2], if
      skb allocation succeeded.
      
      In a follow-up patch, we might abort tcp_send_fin() infinite loop
      in case TIF_MEMDIE is set on this thread, as memory allocator
      did its best getting extra memory already.

       "As always, this tends to be one of our bigger branches.  There are
        lots of updates this release, but not that many jumps out as something
        that needs more detailed coverage.  Some of the highlights are:
      
         - DTs for the new Annapurna Labs Alpine platform
      
         - more graphics DT pieces falling into place on Exynos, bridges,
           clocks.
      
         - plenty of DT updates for Qualcomm platforms for various IP blocks
      
         - some churn on Tegra due to switch-over to tool-generated pinctrl
           data

       "We've got a fairly large cleanup branch this time.  The bulk of this
        is removal of non-DT platforms of several flavors:

           board-file based support
      
         - OMAP removes legacy board files for three more platforms

         - Freescale i.MX25 also removes non-DT platform support"

      Urgent pull request for v4.1 to booting for custom kernel
      .config files that do not have MFD_SYSCON set.
      
      Omaps now have a dependency to MFD_SYSCON for system control
      module generic register area and some clocks with the changes
      done in omap-for-v4.1/prcm-dts branch.
      
      This can be pulled on top of omap-for-v4.1/prcm-dts, or into
      fixes for v4.1.
      
      We already do have a slight MFD_SYSCON dependency for
      REGULATOR_PBIAS for dual voltage MMC cards on the first MMC
      bus for many devices, so from that point of view this can
      also be merged separately from omap-for-v4.1/prcm-dts.
