IPCON Driver

Overview

IPCON (IPC Over Netlink) is a Linux kernel driver that provides an Inter-Process Communication (IPC) mechanism for user-space applications. It is implemented as a generic Netlink protocol family, enabling communication between different processes on the same system.

Features

• Peer-to-Peer Communication: Allows direct communication between named peers.
• Publish-Subscribe Model: Supports group messaging for one-to-many communication.
• Service Discovery: Notifies applications about the creation and removal of services.
• Netlink-Based: Leverages the existing Netlink infrastructure in the Linux kernel.

Building the Driver

To build the IPCON driver, you need to have the Linux kernel source tree and a configured build environment.

1. Configure the kernel: Enable the IPCON option in the kernel configuration (make menuconfig). You can find it under "General setup" -> "IPC Over Netlink(IPCON)".

2. Build the driver: The driver will be built as part of the kernel build process. The following modules will be compiled:

   • main.o
   • ipcon_nl.o
   • ipcon_msg.o
   • ipcon_db.o
   • name_cache.o
   • ipcon_debugfs.o (if CONFIG_DEBUG_FS is enabled)

Usage

For detailed information on how to use the IPCON driver, please refer to the documentation.
