Module random 

Kernel Random Number Generator

This module provides a kernel-level random number generation facility. It abstracts away the underlying entropy sources and provides a unified interface for obtaining random numbers throughout the kernel.

Architecture

The RNG subsystem consists of:

• A central RNG manager that coordinates entropy sources
• Multiple entropy sources (e.g., virtio-rng, hardware RNG, timer jitter)
• A buffered output that can be accessed via CharDevice interface

Usage

use crate::random::RandomManager;

// Get random bytes
let mut buffer = [0u8; 32];
RandomManager::get_random_bytes(&mut buffer);

Structs

Constants
