       "The main kernel side changes were:
      
         - Modernize the kprobe and uprobe creation/destruction tooling ABIs:
      
           The existing text based APIs (kprobe_events and uprobe_events in
           tracefs), are naive, limited ABIs in that they require user-space
           to clean up after themselves, which is both difficult and fragile
           if the tool is buggy or exits unexpectedly. In other words they are
           not really suited for modern, robust tooling.
      
           So introduce a modern, file descriptor based ABI that does not have
           these limitations: introduce the 'perf_kprobe' and 'perf_uprobe'
           PMUs and extend the perf_event_open() syscall to create events with
           a kprobe/uprobe attached to them. These [k,u]probe are associated
           with this file descriptor, so they are not available in tracefs.
      
           (Song Liu)
      
         - Intel Cannon Lake CPU support (Harry Pan)
      
         - Intel PT cleanups (Alexander Shishkin)
      
         - Improve the performance of pinned/flexible event groups by using RB
           trees (Alexey Budankov)
      
         - Add PERF_EVENT_IOC_MODIFY_ATTRIBUTES which allows the modification
           of hardware breakpoints, which new ABI variant massively speeds up
           existing tooling that uses hardware breakpoints to instrument (and
           debug) memory usage.

         - Various Intel PEBS handling fixes and improvements, and other Intel

        There's over 200 tooling commits, here's an (imperfect) list of
        highlights:
      
         - 'perf annotate' improvements:

              improves the navigation along jumps and back. (Arnaldo Carvalho
              de Melo)
      
            * Add the 'P' hotkey in TUI annotation to dump annotation output
              into a file, to ease e-mail reporting of annotation details.
              (Arnaldo Carvalho de Melo)
      
            * Add an IPC/cycles column to the TUI (Jin Yao)
      
            * Improve s390 assembly annotation (Thomas Richter)
      
            * Refactor the output formatting logic to better separate it into
              interactive and non-interactive features and add the --stdio2
              output variant to demonstrate this. (Arnaldo Carvalho de Melo)
      
         - 'perf script' improvements:
      
            * Add Python 3 support (Jaroslav Škarvada)
      
            * Add --show-round-event (Jiri Olsa)
      
         - 'perf c2c' improvements:
      
            * Add NUMA analysis support (Jiri Olsa)
      
         - 'perf trace' improvements:
      
            * Improve PowerPC support (Ravi Bangoria)
      
         - 'perf inject' improvements:
      
            * Integrate ARM CoreSight traces (Robert Walker)

            * Add the --timeout option (yuzhoujian)
      
         - 'perf sched' improvements (Changbin Du)
      
         - Vendor events improvements :
      
            * Add IBM s390 vendor events (Thomas Richter)
      
            * Add and improve arm64 vendor events (John Garry, Ganapatrao
              Kulkarni)
      
            * Update POWER9 vendor events (Sukadev Bhattiprolu)
      
         - Intel PT tooling improvements (Adrian Hunter)

      Pull locking updates from Ingo Molnar:
       "The main changes in the locking subsystem in this cycle were:
      
         - Add the Linux Kernel Memory Consistency Model (LKMM) subsystem,
           which is an an array of tools in tools/memory-model/ that formally
           describe the Linux memory coherency model (a.k.a.
           Documentation/memory-barriers.txt), and also produce 'litmus tests'
           in form of kernel code which can be directly executed and tested.
      
           Here's a high level background article about an earlier version of
           this work on LWN.net:
      
              https://lwn.net/Articles/718628/
      
           The design principles:
      
            "There is reason to believe that Documentation/memory-barriers.txt
             could use some help, and a major purpose of this patch is to
             provide that help in the form of a design-time tool that can
             produce all valid executions of a small fragment of concurrent
             Linux-kernel code, which is called a "litmus test". This tool's
             functionality is roughly similar to a full state-space search.
             Please note that this is a design-time tool, not useful for
             regression testing. However, we hope that the underlying
             Linux-kernel memory model will be incorporated into other tools
             capable of analyzing large bodies of code for regression-testing
             purposes."
      
           [...]
      
            "A second tool is klitmus7, which converts litmus tests to
             loadable kernel modules for direct testing. As with herd7, the
             klitmus7 code is freely available from
      
               http://diy.inria.fr/sources/index.html

      net/ipv6: Fix route leaking between VRFs · b6cdbc85
      David Ahern authored
      Donald reported that IPv6 route leaking between VRFs is not working.
      The root cause is the strict argument in the call to rt6_lookup when
      validating the nexthop spec.
      
      ip6_route_check_nh validates the gateway and device (if given) of a
      route spec. It in turn could call rt6_lookup (e.g., lookup in a given
      table did not succeed so it falls back to a full lookup) and if so
      sets the strict argument to 1. That means if the egress device is given,
      the route lookup needs to return a result with the same device. This
      strict requirement does not work with VRFs (IPv4 or IPv6) because the
      oif in the flow struct is overridden with the index of the VRF device
      to trigger a match on the l3mdev rule and force the lookup to its table.
      
      The right long term solution is to add an l3mdev index to the flow
      struct such that the oif is not overridden. That solution will not
      backport well, so this patch aims for a simpler solution to relax the
      strict argument if the route spec device is an l3mdev slave. As done
      in other places, use the FLOWI_FLAG_SKIP_NH_OIF to know that the
      RT6_LOOKUP_F_IFACE flag needs to be removed.

      vrf: Fix use after free and double free in vrf_finish_output · 82dd0d2a
      David Ahern authored
      Miguel reported an skb use after free / double free in vrf_finish_output
      when neigh_output returns an error. The vrf driver should return after
      the call to neigh_output as it takes over the skb on error path as well.
      
      Patch is a simplified version of Miguel's patch which was written for 4.9,
      and updated to top of tree.

      ipv6: sr: fix seg6 encap performances with TSO enabled · 5807b22c
      David Lebrun authored
      
      
      Enabling TSO can lead to abysmal performances when using seg6 in
      encap mode, such as with the ixgbe driver. This patch adds a call to
      iptunnel_handle_offloads() to remove the encapsulation bit if needed.
