Collection of Linux Kernel Modules and PoC to discover, learn and practice Linux Kernel Development

Implement a linux driver. This driver must take the form of a loadable kernel module. Inside the loadable kernel module, I must implement a virtual character device. This virtual character device must enable the user to play a game of Reversi(Othello) against the CPU.

CS-550-Operating Systems - Spring 2020

To develop and use kernel modules and character devices. And learn how the Linux OS maintains list of processes and their execution states.

A Linux kernel module that implements a thread-safe circular buffer logger as a character device (/dev/klogger). Provides a simple interface for userspace applications to write and read log messages with automatic buffer management. Ideal for kernel-level debugging, monitoring, and logging purposes.

A kernel module that creates a device that always returns EIO on a read, for testing purposes.

Development of Device Driver ( Character device / null driver)

CharPulse is a Linux character device driver with a dynamically resizing kernel buffer. It supports read, write, append, and clear operations, allowing storage of large amounts of data safely.

A simple character device driver implemented as loadable Linux kernel module.

Linux character device driver

Kernel level miscellaneous character device to exchange information between user-level processes. The device maintains a thread-safe FIFO queue containing a configurable number of data blocks.

Linux kernel module: character device driver implementing message slots IPC mechanism. Demonstrates IOCTL commands (MSG_SLOT_CHANNEL, MSG_SLOT_SET_CEN), user-space/kernel-space data transfer, lazy allocation, atomic operations, and error handling. Includes kernel source, user-space apps, comprehens ocumentation, and Docker development environment
