[PATCH v4 1/2] integrity: Report error code in integrity_audit_msg() call sites

[sashiko-bot at kernel.org]

> integrity_audit_msg() hides error codes by wrapping
> integrity_audit_message() which obfuscates the underlying reason for the
> failure.
> 
> Update integrity_audit_msg() to take a errno argument, and pass that
> through to integrity_audit_message(). Then update call sites to
> take caller's respective error codes.
> 
> ima_appraise_measurement() stores xattr_len as the return code, but
> can replace it with a error code later. Therefore conditionally use
> a code if rc < 0, otherwise report zero. Lastly, conditionally use
> -EINVAL for ima_release_policy().
