  • Make the determination of the trustworthiness of a key dependent on whether
    a key that can verify it is present in the supplied ring of trusted keys
    rather than whether or not the verifying key has KEY_FLAG_TRUSTED set.

    verify_pkcs7_signature() will return -ENOKEY if the PKCS#7 message trust
    chain cannot be verified.

  • Generalise system_verify_data() to provide access to internal content
    through a callback. This allows all the PKCS#7 stuff to be hidden inside
    this function and removed from the PE file parser and the PKCS#7 test key.

    If external content is not required, NULL should be passed as data to the
    function. If the callback is not required, that can be set to NULL.

    The function is now called verify_pkcs7_signature() to contrast with
    verify_pefile_signature() and the definitions of both have been moved into
    linux/verification.h along with the key_being_used_for enum.
