Abstract: Detection of alteration of storage keys used to protect memory includes determining whether a storage key alteration event has occurred within a processor of a computing environment. The determining includes checking whether one or more selected fields of a storage key have been updated. The storage key is associated with a block of memory and controls access to the block of memory. Based on the checking indicating that the one or more selected fields of the storage key have been updated, a storage key alteration event has been detected. Based on determining the storage key alteration event has occurred, a notification is provided.

Abstract: Saving and restoring machine state between multiple executions of an instruction. A determination is made that processing of an operation of an instruction executing on a processor has been interrupted prior to completion. Based on determining that the processing of the operation has been interrupted, current metadata of the processor is extracted. The metadata is stored in a location associated with the instruction and used to re-execute the instruction to resume forward processing of the instruction from where it was interrupted.
