Abstract: An inter-process messaging security management may be provided. A message comprising an operation to be performed may be sent from a process operating in a process chamber to a second process operating in another chamber. Before the message is allowed to be delivered, the validity of the operation contained in the message may be verified and a security policy may be examined to determine whether the message is permitted to be sent from the first process to the second process. If the security policy permits the second process to execute the operation requested by the first process, the message may be delivered to the second process. If the operation is not permitted, the message may not be delivered and an error message may be returned to the first process.

Abstract: A method of managing memory of a computing device includes providing a first memory that can be allocated as cache memory or that can be used by a computing device component. A first memory segment can be allocated as cache memory in response to a cache miss. Cache size can be dynamically increased by allocating additional first memory segments as cache memory in response to subsequent cache misses. Cache memory size can be dynamically decreased by reallocating first memory cache segments for use by computing device components. The cache memory can be a cache for a second memory accessible to the computing device. The computing device can be a mobile device. The first memory can be an embedded memory and the second memory can comprise embedded, removable or external memory, or any combination thereof. The maximum size of the cache memory scales with the size of the first memory.

Abstract: A transaction log for flash recovery includes a chained sequence of blocks specifying the operations that have been performed, such as a write to a sector or an erase to a block. Checkpoints are performed writing the entire flash state to flash. Once a checkpoint is performed, all of the log entries prior to the checkpoint are deleted and the log processing on recovery begins with the latest checkpoint. If the system is able to safely shutdown, then a checkpoint may be performed before the driver unloads, and on initialization, the entire persisted flash state may be loaded into the flash memory with a minimal amount of flash scanning. If a power failure occurs during system operation, then on the next boot-up, only the sectors or blocks specified in the log entries after the latest checkpoint have to be scanned, rather than all the sectors on the part.

Abstract: Recovery is expedited for crashes involving flash memory. Rather than requiring an entire flash memory to be read to reconstruct lost information, only a subset of the memory need be read thereby reducing system down time, among other things. In particular, state information such as a logical to physical mapping is captured via a checkpoint operation periodically. Moreover, a deterministic usage pattern is employed to facilitate recovery of actions performed after a checkpoint.

Abstract: In-place data transformations are performed on file data by moving data blocks from a source file into a temporary file and then from the temporary file into a destination file each time in a back to front fashion enabling truncation of the source file while the temporary file is being expanded and written into. Similar read, write, and truncate operations are performed between the temporary and destination files as well resulting in optimized use of available disk and/or memory space. An initial log file with information such as source file name, size, transformation type and direction is generated for recovery from a mid-transaction interruption. Based on a state (truncation, data content) of the temporary and source files, a status of data transfer prior to interruption is determined and remaining data transferred.

Abstract: A User Brokered Authorization (UBA) mechanism for policy decisions in a computing device is provided. The authorization mechanism interacts with an authorization layer of the computing device's operating system and enables a determination of whether an authorization decision can be made programmatically or by end user decision based on generalized device policy.

Abstract: Described is a system and method used in manufacturing computer devices, in which a single manufacturing image file contains an internal partition and file system layout into which individual operating system component packages are written. The image file is independent of any particular storage technology. To generate the file, a disk image utility tool inputs a memory configuration file and a package-to-partition mapping file to create the partitions/file systems within the image file. The operating system components (package) are written into the partitions. To store (e.g., flash) the image file's data on a particular storage device, the image file is post-processed to customize the data for a particular storage device.
