      perf bperf: Avoid use after free via unrelated 'struct evsel' anonymous union field · e0137336
      Ian Rogers authored
      If bperf (perf tools that use BPF skels) sets evsel->leader_skel or
      evsel->follower_skel then it appears that evsel->bpf_skel is set and can
      trigger the following use-after-free:

      perf script ibs: Change bit description according to latest AMD PPR ("Processor Programming Reference")
      
      Some of the IBS_OP_DATA2 bit descriptions were stale (taken from old
      version of PPR). Change it according to latest PPR.

      perf mem: Increase HISTC_MEM_LVL column size to 39 chars · 4953c897
      Ravi Bangoria authored
      39 is taken from the length of longest printable new API string:
      "Remote socket, same board Any cache hit". Although, using old API
      can result into even longer strings, let's not overkill by making
      it dynamic length.

      perf mem: Refactor perf_mem__lvl_scnprintf() to process 'union perf_mem_data_src' more intuitively · ddeac198
      Ravi Bangoria authored
      Interpretation of 'union perf_mem_data_src' by perf_mem__lvl_scnprintf()
      is non-intuitive. For ex, it ignores 'mem_lvl' when 'mem_hops' is set
      but considers it otherwise. It prints both 'mem_lvl_num' and 'mem_lvl'
      when 'mem_hops' is not set.
      
      Refactor this function such that it behaves more intuitively: Use new
      API 'mem_lvl_num'|'mem_remote'|'mem_hops' if 'mem_lvl_num' contains
      value other than PERF_MEM_LVLNUM_NA. Otherwise, fallback to old API
      'mem_lvl'.  Since new API has no way to indicate MISS, use it from old
      api, otherwise don't club old and new APIs while parsing as well as
      printing.
