Abstract: Methods and apparatus for efficient data transfer within a user space network stack. Unlike prior art monolithic networking stacks, the exemplary networking stack architecture described hereinafter includes various components that span multiple domains (both in-kernel, and non-kernel). For example, unlike traditional “socket” based communication, disclosed embodiments can transfer data directly between the kernel and user space domains. Direct transfer reduces the per-byte and per-packet costs relative to socket based communication. A user space networking stack is disclosed that enables extensible, cross-platform-capable, user space control of the networking protocol stack functionality. The user space networking stack facilitates tighter integration between the protocol layers (including TLS) and the application or daemon. Exemplary systems can support multiple networking protocol stack instances (including an in-kernel traditional network stack).

Abstract: Methods and apparatus for dynamic packet pool configuration in networking stack architectures. Unlike prior art monolithic memory allocations, embodiments of the present disclosure enable packet pools associated with non-kernel space applications to dynamically allocate additional memory allocations to a given non-kernel space application, or conversely, de-allocate memory allocations to a given non-kernel space application. Variants also disclose the splitting up of a memory allocation into device accessible portions and kernel accessible portions. Other variants disclose sizing certain segment allocations so as to be a multiple of a physical address page size. Such a variant enables a single input/output (I/O) bus address lookup for the given segment so as to minimize look up costs associated with an I/O lookup for the given segment.

Abstract: Some embodiments of the invention provide a novel architecture for debugging devices. This architecture includes numerous devices that without user intervention automatically detect and report bug events to a set of servers that aggregate and process the bug events. When a device detects a potential bug event, the device in some embodiments generates a description of the potential bug event, and sends the generated description to the server set through a network. In addition to generating such a description, the device in some embodiments directs one or more of its modules to gather and store a collection of one or more data sets that are relevant to the potential bug event, in case the event has to be further analyzed by the server set. In the discussion below, the generated bug-event description is referred to as the event signature, while the gathered collection of data sets for an event is referred to as the event's data archive. The server set aggregates and processes the bug-event signatures that it receives from the various devices. For only a subset of the reported bug-event signatures, the server set then directs the devices that sent these signatures to also send the data archives that these devices have gathered and stored for the events associated with these signatures. These data archives can be further analyzed to identify the root causes of the bug events.
