Please pull these updates for the Integrity subsystem, via Mimi:

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

Also note the addition of a new cred_getsecid LSM hook by Matthew Garrett:

    For IMA purposes, we want to be able to obtain the prepared secid in 
    the bprm structure before the credentials are committed. Add a 
    cred_getsecid hook that makes this possible.

which is used by a new CREDS_CHECK target in IMA:

    In ima_bprm_check(), check with both the existing process credentials 
    and the credentials that will be committed when the new process is 
    started. This will not change behaviour unless the system policy is 
    extended to include CREDS_CHECK targets - BPRM_CHECK will continue to 
    check the same credentials that it did previously.
