摘要： A software version management system comprising a host driver and at least one software module. The host driver comprises migration means to start, stop and replace the software modules on a computer system in response to replacement actions. The system is characterized by the software module being a downgradable software module comprising a compatibility database specifying dependencies between different versions of the software module; the migration means further comprising i) at least a status means to retrieve temporal information from the downgradable software module; ii) at least a downgrading means responsive to a replacement action to downgrade the downgradable software module to a particular downgrade version and to the status means, the downgrading means identifying an intermediate version of the downgradable software module; the host driver comprising restarting means responsive to the report of the completion of the intermediate version to load and start the downgrade version of the software module.

摘要： A computing system may be protected from revoked system updates. A computing system receives an object and scans it for revocation updates to a security structure of the computing system. The security structure is a monotonically nondecreasing collection of segments containing data on whether a system update is revoked, and a system update's status as revoked signifies the revoked system update can no longer be used by the computing system. Based upon scanning the object, the computing system identifies and validates a revocation update. The computing system resolves the revocation update by applying the revocation update to the security structure, by adding or changing one or more segments of the security structure identified by the revocation update, in response to determining that the revocation update is valid, or by denying application of the revocation update to the security structure in response to determining that the revocation update is invalid.

摘要： 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.

摘要： A cryptographic hardware security module (HSM) includes a memory storage device and an immutable hardware unit in signal communication with the memory storage device. The memory storage device is configured to store firmware. The immutable hardware unit is configured to perform a hash operation on targeted firmware stored in the memory storage device to determine an authenticity of the targeted firmware based at least in part on results of the hash operation.

摘要： A method, system, and computer program product for performing robust, parallel data transfer by a processor device. Data is segmented into k-bit segments, where k≧1. The k-bit segments are convolution encoded, using m≧1 stages of delay. The n output streams are transmitted in parallel for increased effective data rate, where n>k. The n output streams are received. An XOR (Exclusive OR) logic is applied to the n output streams with pathing allowed by the convolution encoding, in a trellis-decoding diagram.
