[GIT PULL] KEYS fixes

[James Morris <jmorris@namei.org>]

Please pull these fixes for the keys code.

>From David Howells:

" Here are three miscellaneous fixes:

 (1) Fix a panic in some debugging code in PKCS#7.  This can only happen 
     by explicitly inserting a #define DEBUG into the code.

 (2) Fix the calculation of the digest length in the PE file parser.  This
     causes a failure where there should be a success.

 (3) Fix the case where an X.509 cert can be added as an asymmetric key to
     a trusted keyring with no trust restriction if no AKID is supplied.

  Bugs (1) and (2) aren't particularly problematic, but (3) allows a 
  security check to be bypassed.  Bug (3) is added since the 4.6 kernel. "
