safety/README

   1 This is a static safety-checker for SystemTap modules.  It attempts to
   2 validate modules by checking the opcodes used and the external references
   3 against a whitelist.

   5 The script relies on external data files to provide the whitelists, which by
   6 default are in the <script-dir>/data directory.  The 'references' file
   7 provides a plain list of allowed references.  The 'opcodes' file provides a
   8 list of regular expressions that match allowed opcodes.  Either data file may
   9 have an optional kernel and/or architecture suffix, as in 'opcodes-i686' or
  10 'references-2.6.9-32.ELsmp-x86_64'.
