Abstract: A message limit value to be used in enqueuing one or more messages on a queue of a device of the computing environment is obtained. The message limit value indicates whether an extended maximum message length is supported by the device. The extended maximum message length is different from a default maximum message length supported by the device. Based on determining that the extended maximum message length is supported and that the obtained message limit value has a defined relationship with a select value, at least one message of an extended length is enqueued on the queue of the device.

Abstract: A method, computer program product, and computer system are provided. A machine hypervisor builds and enqueue a zeroize adjunct processor (AP) domain (ZAPD) common command request message to a target AP domain queue. Machine firmware validates the enqueued common command request message on the target AP domain queue. The machine firmware converts the ZAPD command request to the mode-specific form of the domain zeroize request. A command request message is executed at an AP crypto adapter of the target AP domain. Executing includes zeroizing a storage area of the AP crypto adapter. The execution results are returned to the machine firmware. The machine firmware converts the crypto card mode's ZAPD command reply message into the common ZAPD command reply message. The final execution results including the converted common ZAPD command reply message are returned to the machine hypervisor.

Abstract: Method, computer program product, and computer system are provided. Program queries for an indicator of dependency between a usage domain and a control domain in a virtual machine (VM) configuration having a cryptographic AP adapter. The VM and the cryptographic AP adapter are both installed on a hardware server. Program sets an internal bitmap based on a result and generates one or more sets of AP commands, based on the setting of the internal bitmap. The sets of AP commands are directed to an adjunct processor (AP) message queue on a cryptographic AP in the VM configuration. Program enqueues the one or more sets of program instructions to the VM having an identifier corresponding to an offset in the program internal bitmap. Program receives status at completion of the one or more sets of AP commands from the VM having the cryptographic AP in the VM configuration.

Abstract: A method, computer program product, and computer system are provided. A message storage area of an adjunct processor (AP) crypto adapter is filled with a plurality of command request messages sufficient to maximize utilization and performance of the AP crypto adapter. In response to detecting an error during execution of one of the plurality of command request messages, generating an AP crypto adapter command reply message. The AP crypto adapter command reply message includes the error. In response to the error being a non-recoverable failure, determining a state of the command request message, wherein the state of the command request message comprises an in-process state or a request-pending state. The AP crypto adapter command reply message is formatted, wherein the formatted AP crypto adapter command reply message is stored in a message queue in the AP crypto adapter pending completion of machine failure recovery. The AP crypto adapter is recovered.

Abstract: An initial program load of a system component of a computing environment is performed. A determination is made as to whether one or more signatures of one or more signed binary code components relating to the system component are verified. Based on determining that the one or more signatures are verified, additional verification is performed. The additional verification includes obtaining a select binary code component of one or more binary code components relating to the system component and determining whether the select binary code component is a particular signed binary code component. Based on determining that the select binary code component is the particular signed binary code component, a check is performed. The initial program load is continued based on a successful check.

Abstract: A method, computer program product, and computer system are provided. An operating system (OS) receives a status at completion of a cryptographic adjunct process (AP) instruction directed to an AP message queue on a cryptographic AP. The status includes a return code, a reason code, a queue full indicator, a queue empty indicator, and the count of enqueued request messages on the AP message queue. The OS determines a number of lost request messages on the AP message queue, based on a count of enqueued request messages on the AP message queue received in the status. The OS re-enqueues the number of lost request messages to the AP message queue. The OS recovers the number of lost request messages on the AP message queue.

Abstract: An adjunct processor dynamically determines, on a per-command basis, whether commands obtained by the adjunct processor are to be processed by the adjunct processor. The adjunct processor obtains a command request of a requester. The command request includes at least one filtering indicator indicating at least one valid command type for processing by the adjunct processor for the requester. The adjunct processor determines using the at least one filtering indicator whether a command of the command request is valid for processing by the adjunct processor for the requester. Based on determining that the command is valid for processing by the adjunct processor, the command is processed by the adjunct processor.

Abstract: Adjunct processor command-type filtering includes determining whether a target adjunct processor is configured to support a selected command-type filtering mode, and whether another adjunct processor is configured to support the selected command-type filtering mode. Based on determining that the target adjunct processor is not configured to support the selected command-type filtering mode and based on the other adjunct processor being configured to support the selected command-type filtering mode, a command is forwarded to the other adjunct processor for processing to determine whether the command is valid for the selected command-type filtering mode. An indication is obtained, based on processing at the other adjunct processor, of whether the command is valid for the selected command-type filtering mode. Based on obtaining an indication that the command is valid for the selected command-type filtering mode, the command is sent to the target adjunct processor for execution.

Abstract: A processor requests that a data transformation operation be performed using another processor, in which the data transformation operation is performed asynchronously. A determination is made that the data transformation operation performed using the other processor has completed unsatisfactorily, and based on the unsatisfactory completion, status relating to performance of the data transformation operation is incomplete. The data transformation operation is then re-executed synchronously using the one processor, and the re-executing provides status information unavailable in performing the data transformation operation asynchronously.
