New Revision: 292848
URL: https://svnweb.freebsd.org/changeset/base/292848

Log:
  MFstable/10 r292845:
  
  MFC r292569:
  
  Make the mac_portacl testcases work / more robust
  
  - A trap(1) call has been added to the test scripts to better
    ensure that the tests do a better job at trying to restore the
    test host state at the end of the tests (if the test was
    interrupted before it would leave the system in an odd state,
    potentially making the test results for subsequent runs
    non-deterministic).
  - Add root user checks
  - Fix nc(1) usage:
    -- -o is deprecated
    -- Using `-w 10` will make the call timeout after 10 seconds so it
       doesn't block indefinitely
  - Use local variables
  - Be more terse in the error messages
  - Parameterize out "127.0.0.1"
