      perf bpf: Add 'examples' directories · 8f12a2ff
      Arnaldo Carvalho de Melo authored
      The first one is the bare minimum that bpf infrastructure accepts before
      it expects actual events to be set up:
      
        $ cat tools/perf/examples/bpf/empty.c
        char _license[] __attribute__((section("license"), used)) = "GPL";
        int _version __attribute__((section("version"), used)) = LINUX_VERSION_CODE;
        $
      
      If you remove that "version" line, then it will be refused with:
      
        # perf trace -e tools/perf/examples/bpf/empty.c
        event syntax error: 'tools/perf/examples/bpf/empty.c'
                             \___ Failed to load tools/perf/examples/bpf/empty.c from source: 'version' section incorrect or lost
      
        (add -v to see detail)
        Run 'perf list' for a list of valid events
      
         Usage: perf trace [<options>] [<command>]
            or: perf trace [<options>] -- <command> [<options>]
            or: perf trace record [<options>] [<command>]
            or: perf trace record [<options>] -- <command> [<options>]
      
            -e, --event <event>   event/syscall selector. use 'perf list' to list available events
        #
      
      The next ones will, step by step, show simple filters, then the needs
      for headers will be made clear, it will be put in place and tested with
      new examples, rinse, repeat.
      
      Back to using this first one to test the perf+bpf infrastructure:
      
      If we run it will fail, as no functions are present connecting with,
      say, a tracepoint or a function using the kprobes or uprobes
      infrastructure:
      
        # perf trace -e tools/perf/examples/bpf/empty.c
        WARNING: event parser found nothing
        invalid or unsupported event: 'tools/perf/examples/bpf/empty.c'
        Run 'perf list' for a list of valid events
      
         Usage: perf trace [<options>] [<command>]
            or: perf trace [<options>] -- <command> [<options>]
            or: perf trace record [<options>] [<command>]
            or: perf trace record [<options>] -- <command> [<options>]
      
            -e, --event <event>   event/syscall selector. use 'perf list' to list available events
        #
      
      But, if we set things up to dump the generated object file to a file,
      and do this after having run 'make install', still on the developer's
      $HOME directory:
      
        # cat ~/.perfconfig
        [llvm]
      
      	dump-obj = true
        #
        # perf trace -e ~acme/lib/examples/perf/bpf/empty.c
        LLVM: dumping /home/acme/lib/examples/perf/bpf/empty.o
        WARNING: event parser found nothing
        invalid or unsupported event: '/home/acme/lib/examples/perf/bpf/empty.c'
        <SNIP>
        #
      
      We can look at the dumped object file:
      
        # ls -la ~acme/lib/examples/perf/bpf/empty.o
        -rw-r--r--. 1 root root 576 May  4 12:10 /home/acme/lib/examples/perf/bpf/empty.o

      perf tests parse-events: Add intel_pt parse test · b3f58c8d
      Arnaldo Carvalho de Melo authored
      To avoid regressions such as the one fixed by 4a35a902 ("Revert
      "perf pmu: Fix pmu events parsing rule""), where '-e intel_pt//u' got
      broken, with this new entry in this 'perf tests' subtest, we would have
      caught it before pushing upstream.

      net sched actions: fix refcnt leak in skbmod · a52956df
      Roman Mashak authored
      When application fails to pass flags in netlink TLV when replacing
      existing skbmod action, the kernel will leak refcnt:
      
      $ tc actions get action skbmod index 1
      total acts 0
      
              action order 0: skbmod pipe set smac 00:11:22:33:44:55
               index 1 ref 1 bind 0
      
      For example, at this point a buggy application replaces the action with
      index 1 with new smac 00:aa:22:33:44:55, it fails because of zero flags,
      however refcnt gets bumped:
      
      $ tc actions get actions skbmod index 1
      total acts 0
      
              action order 0: skbmod pipe set smac 00:11:22:33:44:55

      In case modules are not configured, error out when tp->ops is null
      and prevent later null pointer dereference.

      ====================
      Intel Wired LAN Driver Updates 2018-05-11
      
      This series contains fixes to the ice, ixgbe and ixgbevf drivers.
      
      Jeff Shaw provides a fix to ensure rq_last_status gets set, whether or
      not the hardware responds with an error in the ice driver.
      
      Emil adds a check for unsupported module during the reset routine for
      ixgbe.
      
      Luc Van Oostenryck fixes ixgbevf_xmit_frame() where it was not using the
      correct return value (int).
      
      Colin Ian King fixes a potential resource leak in ixgbe, where we were
      not freeing ipsec in our cleanup path.
