Encryption architecture
For a host that executes one or more guest virtual machines (GVMs), some embodiments provide a novel encryption method for encrypting the data messages sent by the GVMs. The method initially receives a data message to send for a GVM executing on the host. The method then determines whether it should encrypt the data message based on a set of one or more encryption rules. When the process determines that it should encrypt the received data message, it encrypts the data message and forwards the encrypted data message to its destination; otherwise, the method just forwards the received data message unencrypted to its destination. In some embodiments, the host encrypts differently the data messages for different GVMs that execute on the host. When two different GVMs are part of two different logical overlay networks that are implemented on common network fabric, the method in some embodiments encrypts the data messages exchanged between the GVMs of one logical network differently than the data messages exchanged between the GVMs of another logical network. In some embodiments, the method can also encrypt different types of data messages from the same GVM differently. Also, in some embodiments, the method can dynamically enforce encryption rules in response to dynamically detected events, such as malware infections. |

Buffer overflow exploit detection
A call to a memory management application programming interface (API) that results in a buffer overflow due to inaccurate bounds checking could potentially leave the system vulnerable to being exploited by a third party. Approaches presented herein can monitor calls to these APIs in order to determine typical memory sizes passed to these APIs. During an initial baselining period a number of profiles are generated that indicate expected memory size parameters under various different call conditions, such from specific sources or call stacks. Comparing subsequently received API calls against the expected values from the relevant profile enables the legitimacy of an API call to be determined with relatively high accuracy. A suspicious call is identified based at least in part upon determining that the memory size of the call falls outside an expected range for that API and the relevant context. |

Bus-based cache architecture
Digital signal processors often operate on two operands per instruction, and it is desirable to retrieve both operands in one cycle. Some data caches connect to the processor over two busses and internally uses two or more memory banks to store cache lines. The allocation of cache lines to specific banks is based on the address that the cache line is associated. When two memory accesses map to the same memory bank, fetching the operands incurs extra latency because the accesses are serialized. An improved bank organization for providing conflict-free dual-data cache access—a bus-based data cache system having two data buses and two memory banks—is disclosed. Each memory bank works as a default memory bank for the corresponding data bus. As long as the two values of data being accessed belong to two separate data sets assigned to the two respective data buses, memory bank conflicts are avoided. |

After the copying is complete, the transaction log is marked as ‘free’. Cache values modified in the transaction may be written back to persistent memory when evicted, and values read in the transaction may be read from the cache rather than from the transaction log. |

Memory controller with at least one address segment defined for which data is striped across flash memory dies, with a common address offset being used to obtain physical addresses for the data in each of the dies
This disclosure provides for improvements in managing multi-drive, multi-die or multi-plane NAND flash memory.

For multi-plane designs, the host writes related data in a manner consistent with multi-plane device addressing limitations. The host is therefore able to “plan ahead” in a manner supporting host issuance of true multi-plane read commands. |

Smoke screen generator
The present invention provides a smoke screen generator with a high diffusion rate of a smoke screen.Ends at both sides of a cylindrical housing are closed by a first closure 20 and a second closure 30 respectively, and a flow path changing member 60 is attached at an interval in an axial direction from the second closure 30. At the time of actuation, a smoke screen source passes through a smoke screen source discharge port 38, first discharge flow paths 44, 45 and 46, and a second discharge flow path 47 and is discharged from a final discharge port 48. Since the smoke screen source is radially discharged from the final discharge port 48, a diffusion rate of a smoke screen increases. |
