Abstract: Methods, apparatus, and processor-readable storage media for secure boot and operating system management are provided herein. An example method includes configuring a first set of settings associated with a boot process for validating software components, where at least one of the software components is executed in a user space of an operating system. The method includes verifying, in response to obtaining a request to initiate the boot process, a second set of settings that is currently assigned to the boot process based on a comparison of the first set of settings and the second set of settings, and performing the boot process based on a result of the verifying, wherein the boot process comprises validating the software components based at least in part on the verified second set of settings and respective signatures computed for the software components, and initiating an automated action based on a result of the validating.

Abstract: This application provides a product service configuration method and apparatus. The method includes: obtaining a platform baseline configuration file, where the platform baseline configuration file includes a first configuration item for a platform baseline; obtaining a first product service configuration file, where the first product service configuration file includes a second configuration item for a first product service, and the first configuration item and the second configuration item have a same identifier; and generating a combined configuration file based on the platform baseline configuration file and the first product service configuration file, where the combined configuration file includes a third configuration item, and the third configuration item is obtained based on the first configuration item and the second configuration item that have the same identifier.

Abstract: A clock synchronization apparatus, an optical transmitter, an optical receiver, and a clock synchronization method are provided. In the clock synchronization apparatus, a digital interpolator adjusts a sampling clock frequency of a digital signal under sampling clock control of a clock control circuit.
