Subject: [PATCH 0/3] KEYS: Miscellaneous fixes


Hi James,

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.

The patches can be found here also:
