Abstract: Space reporting in a storage system, including: determining, for one or more system-visible objects in the storage system, an amount of physical space consumed by each system-visible object and an amount of logical space consumed by each system-visible object; identifying, for each of the one or more system-visible objects in the storage system, one or more user-visible objects that reference the system-visible object; determining, for each of the one or more user-visible objects, an amount of physical space consumed by the user-visible object in dependence upon the amount of physical space consumed by each system-visible object referenced by the user-visible object; and determining, for each of the one or more user-visible objects, an amount of logical space consumed by the user-visible object in dependence upon the amount of logical space consumed by each system-visible object referenced by the user-visible object.

Abstract: Embodiments include method, systems, and computer program products for filtering trust services records. Embodiments include receiving a trust services record that includes a plurality of security components and that is usable to secure data that is stored in an untrusted location. It is determined whether the trust services record has been tampered with, including verifying each of the plurality of security components of the trust services record. The trust services record is filtered based on the determination of whether the trust services record has been tampered with. The filtering includes, when the trust services record is determined to have not been tampered with, allowing performance of at least one task with respect to the secured data; and, when the trust services record is determined to have been tampered with, disallowing performance of any task with respect to the secured data.

Abstract: Embodiments are directed to securely filtering trust services records. In one scenario, a client computer system receives at least one of the following trust services records: a trust services certificate, a principal certificate, a group certificate and a trust services policy. The client computer system performs a time validity check to validate the trust services record's timestamp, performs an integrity check to validate the integrity of the trust services record and performs a signature validity check to ensure that the entity claiming to have created the trust services record is the actual creator of the trust services record. The client computer system then, based on the time validity check, the integrity check and the signature validity check, determines that the trust services record is valid and allows a client computer system user to perform a specified task using the validated trust services record.
