Title:
  Ping: checks payloads incorrectly, ignores all mismatch replies

Status in iputils package in Ubuntu:
  Fix Released

Bug description:
  = Impact =

  the ping statistics are incorrect when dealing with truncated packets

  = Test case =

  $ ping -c 1 -s 1200 8.8.8.8

  = Regression potential =

  the changes are limited to the ping source any regression would impact
  that utility, check that responses are correctly handled and
  statistics reflecting what is expected
