  commit ce2f42605888f18f63ff9fe0d45dd69ae83045bb
  Author: George Dunlap <george.dunlap@xxxxxxxxxx>
  Date:   Tue Nov 6 15:41:25 2018 +0000
  
      tools/dm_depriv: Add first cut RLIMITs
      
      Limit the ability of a potentially compromised QEMU to consume system
      resources.  Key limits:
       - RLIMIT_FSIZE (file size): 256KiB
       - RLIMIT_NPROC (after uid changes to a unique uid)
      
      Probably unnecessary limits but why not:
       - RLIMIT_CORE: 0
       - RLIMIT_MSGQUEUE: 0
       - RLIMIT_LOCKS: 0
       - RLIMIT_MEMLOCK: 0
      
      NB that we do not yet set RLIMIT_AS (total virtual memory) or
      RLIMIT_NOFILES (number of open files), since these require more care
      and/or more coordination with QEMU to implement.

      Changes since v4:
      - Put global headers before local headers (sugg by Paul)
      - Move #undif inside the braces (sugg by Paul)
      
      Changes since v3:
      - Align RLIMIT_ENTRY list for easier reading
      - Fix wrong format string specifier
      - Get rid of some trailing whitespace
      
      Changes since v2:
      - Use a macro to define rlimit entries
      - Use RLIMIT_NLIMITS as an end-of-list marker, rather than -1
      - Various style clean-ups
