[PATCH v2 0/3] provide check for ro_after_init memory sections

Show all headers | View raw

Provide a mechansim for other functions to verify that their arguments
are read-only. Use this mechansim in the vmbus register functions to
reject arguments that fail this test.

This implements a suggestion made by Kees Cook for the Kernel Self
Protection Project:

    * provide mechanism to check for ro_after_init memory areas, and
      reject structures not marked ro_after_init in vmbus_register()

I have successfully compiled this series on next-20170215 for x86.

Eddie Kovsky (3):
  module: verify address is read-only
  extable: verify address is read-only
  Make vmbus register arguments read-only
