To use the get_random_bytes()
function in a Linux kernel module, you need to follow these steps:
1
|
#include <linux/random.h> |
1 2 |
#define BUF_SIZE 16 unsigned char buf[BUF_SIZE]; |
1
|
get_random_bytes(buf, BUF_SIZE); |
Here's a simple example showing the usage of get_random_bytes()
:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 |
#include <linux/module.h> #include <linux/random.h> #define BUF_SIZE 16 unsigned char buf[BUF_SIZE]; static int __init my_init(void) { printk(KERN_INFO "Generating random bytes "); get_random_bytes(buf, BUF_SIZE); // Use the generated random bytes as needed return 0; } static void __exit my_exit(void) { // Cleanup if required } module_init(my_init); module_exit(my_exit); MODULE_LICENSE("GPL"); MODULE_DESCRIPTION("Random Bytes Example"); |
Make sure to compile and install the kernel module using the appropriate build system (e.g., make
or kbuild
) for your specific kernel version.
