  • Methods, systems, and computer readable media for caching and using scatter list metadata to control direct memory access (DMA) receiving of network protocol data
    Patent number: 9239796
    Abstract: Methods, systems, and computer readable media for caching and using scatter list metadata to control DMA receiving of network protocol data are described. According to one method, metadata associated with partially used scatter list entries is cached in memory of a scatter list caching engine. Data to be written to host system memory is received. The scatter list caching engine provides the metadata associated with partially used scatter list entries to a DMA controller to control the DMA writing of the data into host system memory.

  • Methods, systems, and computer readable media for automatically generating a fuzzer that implements functional and fuzz testing and testing a network device using the fuzzer
    Patent number: 8819834
    Abstract: Methods, systems, and computer readable media for automatically generating a fuzzer for testing a network device using the fuzzer are disclosed. According to one method, a functional description of a network communications protocol finite state machine is received as input. Operation of the protocol is simulated using the functional description of the network communications protocol finite state machine to generate a set of valid conversations in the protocol. A fuzzer is generated from the set of valid conversations. The fuzzer is used to send messages to test a device under test. Responses to the device under test to the messages generated by the fuzzer are analyzed.
