Hi James,

This pull request contains a mixture of bug fixes, code cleanup, and
continues to close IMA-measurement, IMA-appraisal, and IMA-audit gaps.

Closing measurement, appraisal, and audit gaps:
- A new LSM hook named security_cred_getsecid is defined in order to
validate a file's integrity based on the credentials of the process
going to being executed, not of the existing process.

- Fuse filesystems are inherently untrusted.  Instead of always re-
evaluating files, this pull request differentiates between privileged
and unprivileged mounts, and defines a new builtin policy to fail file
signature verification even on privileged mounted filesystems.

Code cleanup:
- Support for verifying a file's integrity based on an appended
signature (scripts/sign-file) is coming along really nicely.  This
pull request includes some of the cleanup patches from the appended
signature patch series.

thanks,

Mimi
