      rdma: replace deprecated ifconfig in doc · b962dc0a
      Stephen Hemminger authored
      The ifconfig command has been deprecated for many years.
      To encourage new users not to continue using it and learning
      iproute2; the ifconfig should not be used in examples.

      ib_uverbs: Fix pages leak when using XRC SRQs · a233c4b5
      Sébastien Dugué authored
      Hello,
      
        When an application using XRCs abruptly terminates, the mmaped pages
      of the CQ buffers are leaked.
      
        This comes from the fact that when resources are released in
      ib_uverbs_cleanup_ucontext(), we fail to release the CQs because their
      refcount is not 0.
      
        When creating an XRC SRQ, we increment the associated CQ refcount.
      This refcount is only decremented when the SRQ is released.
      
        Therefore we need to release the SRQs prior to the CQs to make sure
      that all references to the CQs are gone before trying to release these.

       1) Add BQL support to via-rhine, from Tino Reichardt.
      
       2) Integrate SWITCHDEV layer support into the DSA layer, so DSA drivers
          can support hw switch offloading.  From Floria Fainelli.
      
       3) Allow 'ip address' commands to initiate multicast group join/leave,
          from Madhu Challa.
      
       4) Many ipv4 FIB lookup optimizations from Alexander Duyck.
      
       5) Support EBPF in cls_bpf classifier and act_bpf action, from Daniel
          Borkmann.
      
       6) Remove the ugly compat support in ARP for ugly layers like ax25,
          rose, etc.  And use this to clean up the neigh layer, then use it to
          implement MPLS support.  All from Eric Biederman.
      
       7) Support L3 forwarding offloading in switches, from Scott Feldman.
      
       8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed
          up route lookups even further.  From Alexander Duyck.
      
       9) Many improvements and bug fixes to the rhashtable implementation,
          from Herbert Xu and Thomas Graf.  In particular, in the case where
          an rhashtable user bulk adds a large number of items into an empty
          table, we expand the table much more sanely.
      
      10) Don't make the tcp_metrics hash table per-namespace, from Eric
          Biederman.
      
      11) Extend EBPF to access SKB fields, from Alexei Starovoitov.
      
      12) Split out new connection request sockets so that they can be
          established in the main hash table.  Much less false sharing since
          hash lookups go direct to the request sockets instead of having to
          go first to the listener then to the request socks hashed
          underneath.  From Eric Dumazet.
      
      13) Add async I/O support for crytpo AF_ALG sockets, from Tadeusz Struk.
      
      14) Support stable privacy address generation for RFC7217 in IPV6.  From
          Hannes Frederic Sowa.
      
      15) Hash network namespace into IP frag IDs, also from Hannes Frederic
          Sowa.
      
      16) Convert PTP get/set methods to use 64-bit time, from Richard
          Cochran.

      Pull ARM updates from Russell King:
       "Included in this update are both some long term fixes and some new
        features.
      
        Fixes:
      
         - An integer overflow in the calculation of ELF_ET_DYN_BASE.
      
         - Avoiding OOMs for high-order IOMMU allocations
      
         - SMP requires the data cache to be enabled for synchronisation
           primitives to work, so prevent the CPU_DCACHE_DISABLE option being
           visible on SMP builds.
      
         - A bug going back 10+ years in the noMMU ARM94* CPU support code,
           where it corrupts registers.  Found by folk getting Linux running
           on their cameras.
      
         - Versatile Express needs an errata workaround enabled for CPU
           hot-unplug to work.
      
        Features:
      
         - Clean up module linker by handling out of range relocations
           separately from relocation cases we don't handle.
      
         - Fix a long term bug in the pci_mmap_page_range() code, which we
           hope won't impact userspace (we hope there's no users of the
           existing broken interface.)
      
         - Don't map DMA coherent allocations when we don't have a MMU.
      
         - Drop experimental status for SMP_ON_UP.
      
         - Warn when DT doesn't specify ePAPR mandatory cache properties.
      
         - Add documentation concerning how we find the start of physical
           memory for AUTO_ZRELADDR kernels, detailing why we have chosen the
           mask and the implications of changing it.
      
         - Updates from Ard Biesheuvel to address some issues with large
           kernels (such as allyesconfig) failing to link.
      
         - Allow hibernation to work on modern (ARMv7) CPUs - this appears to
           have never worked in the past on these CPUs.
      
         - Enable IRQ_SHOW_LEVEL, which changes the /proc/interrupts output
           format (hopefully without userspace breaking...  let's hope that if
           it causes someone a problem, they tell us.)
      
         - Fix tegra-ahb DT offsets.
      
         - Rework ARM errata 643719 code (and ARMv7 flush_cache_louis()/
           flush_dcache_all()) code to be more efficient, and enable this
           errata workaround by default for ARMv7+SMP CPUs.  This complements
           the Versatile Express fix above.
      
         - Rework ARMv7 context code for errata 430973, so that only Cortex A8
           CPUs are impacted by the branch target buffer flush when this
           errata is enabled.  Also update the help text to indicate that all
           r1p* A8 CPUs are impacted.
      
         - Switch ARM to the generic show_mem() implementation, it conveys all
           the information which we were already reporting.
      
         - Prevent slow timer sources being used for udelay() - timers running
           at less than 1MHz are not useful for this, and can cause udelay()
           to return immediately, without any wait.  Using such a slow timer
           is silly.
      
         - VDSO support for 32-bit ARM, mainly for gettimeofday() using the
           ARM architected timer.
      
         - Perf support for Scorpion performance monitoring units"

       "These are mostly fixes and cleanups all over, although there are a few

        First off, we have new callbacks for PM domains that should help us to
        handle some issues related to device initialization in a better way.
      
        There also is some consolidation in the unified device properties API
        area allowing us to use that inferface for accessing data coming from
        platform initialization code in addition to firmware-provided data.

      ====================
      Intel Wired LAN Driver Updates 2015-04-14
      
      This series contains updates to fm10k only.
      
      Fixed transmit statistics which was actually using values from the
      receive ring, instead of the transmit ring.  Fixed up spelling mistakes
      in code comments and resolved unused argument warnings.  Added support
      for netconsole.  Fixed up statistic reporting so that we are only
      reporting from actual queues as well as display PF only stats for
      just the PF and not the VF.  Also fixed an issue that when returning
      virtualization queues from the VF back to the PF, we were retaining
      the VF rate limiter.
      
      Fixed up the driver to use a separate workqueue, which helps reduce
      and stabilize latency between scheduling the work in our interrupt and
      actually performing the work.
      
      Fixed a bug where the VF tried to set a multicast address before
      requesting the required xcast mode.
      
      Fix VF multicast update since VFs were being improperly added to the
      switch's mutlicast group.  The error stems from the fact that incorrect
      arguments were passed to the update_mc_addr().
      
      Thanks to Alex Duyck for the extensive review.

      lsm: copy comm before calling audit_log to avoid race in string printing · 5deeb5ce
      Richard Guy Briggs authored
      When task->comm is passed directly to audit_log_untrustedstring() without
      getting a copy or using the task_lock, there is a race that could happen that
      would output a NULL (\0) in the middle of the output string that would
      effectively truncate the rest of the report text after the comm= field in the
      audit log message, losing fields.
      
      Using get_task_comm() to get a copy while acquiring the task_lock to prevent
      this and to prevent the result from being a mixture of old and new values of
      comm would incur potentially unacceptable overhead, considering that the value
      can be influenced by userspace and therefore untrusted anyways.
      
      Copy the value before passing it to audit_log_untrustedstring() ensures that a
      local copy is used to calculate the length *and* subsequently printed.  Even if
      this value contains a mix of old and new values, it will only calculate and
      copy up to the first NULL, preventing the rest of the audit log message being
      truncated.
      
      Use a second local copy of comm to avoid a race between the first and second
      calls to audit_log_untrustedstring() with comm.
