  commit 817aef260037f33ee0f44c17fe341323d3aebd6d upstream.

• bda850cd2   PKCS#7: Make trust determination dependent on contents of trust keyring ... Browse Code »

  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.

• e68503bd6   KEYS: Generalise system_verify_data() to provide access to internal content ... Browse Code »

  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.
