    IPC: G06F9/54

    Abstract: A device may receive, by a kernel of the device and from a loadable kernel module of the device, information that instructs the kernel to invoke a callback function associated with the loadable kernel module based on an execution of a hook of the kernel. The device may receive, by the kernel of the device and from an application of the device, a socket application programming interface (API) call. The socket API call may include control information. The device may execute, by the kernel of the device, the hook based on receiving the socket API call. The device may invoke, by the kernel of the device, the callback function associated with the loadable kernel module based on executing the hook to permit a functionality associated with the callback function to be provided. The kernel may provide the control information, associated with the socket API call, to the callback function as an argument.

    IPC: G06F3/06

    Abstract: A disclosed method may include (1) publishing, by a writer, a first context that represents a lockless data structure at a first moment in time for access by a set of readers, (2) upon the publication of the first context, directing at least one of the readers to access an object stored in shared memory via the first context, (3) publishing, by the writer, a second context that represents the lockless data structure at a second moment in time for access by the set of readers, and (4) upon the publication of the second context, directing the at least one of the readers to access an additional object stored in the shared memory via the second context. Various other apparatuses, systems, and methods are also disclosed.

    Abstract: A disclosed method may include (1) mapping a block of shared memory to a plurality of processes running on a computing device, (2) determining, for a process within the plurality of processes, a local pointer that references a specific portion of the block of shared memory from a shared memory pointer that is shared across the plurality of processes by (A) identifying, within the shared memory pointer, a block number assigned to the block of shared memory and (B) identifying, within the shared memory pointer, an offset that corresponds to the specific portion of the block of shared memory relative to the process, and then (3) performing an operation on the specific portion of the block of shared memory based at least in part on the local pointer. Various other systems, methods, and computer-readable media are also disclosed.

    IPC: H04L29/06 ,  H04L5/00 ,  H04L29/08

    Abstract: The disclosed method may include (1) receiving a synchronize message from a computing device to initiate synchronization between the computing device and a server with respect to a communication protocol, (2) notifying an application in user space on the server of the synchronize message such that the application in user space selects at least one attribute to be applied to a communication session resulting from the synchronization between the computing device and the server, (3) sending a synchronize acknowledgment that identifies the attribute selected by the application in user space to the computing device to further the synchronization between the computing device and the server, and then (4) establishing the communication session with the attribute selected by the application in user space upon receiving an acknowledgment message from the computing device to complete the synchronization. Various other methods, systems, and apparatuses are also disclosed.
