RUNTIME VERIFICATION
======================================================================

Vmlinux patching test

Step 1: Verifying livepatch is loaded and enabled
  Module name: livepatch_vmlinux
  Livepatch sysfs exists: /sys/kernel/livepatch/livepatch_vmlinux

# Read /sys/kernel/livepatch/livepatch_vmlinux/enabled
$ cat /sys/kernel/livepatch/livepatch_vmlinux/enabled
1

Step 2: Verifying patched function behavior

Step 2a: Checking function return value (should still be 42)

# Read /proc/klp_test
$ cat /proc/klp_test
42
  SUCCESS: Function returns original value (42)

Step 2b: Verifying patched pr_info() in dmesg

$ dmesg | grep 'klp_test: vmlinux PATCHED'
[    4.831456] klp_test: vmlinux PATCHED
  SUCCESS: Patched pr_info() message found in dmesg

Step 3: Disabling livepatch
  Livepatch livepatch_vmlinux disabled

Step 4: Unloading livepatch module
  Module livepatch_vmlinux unloaded

SUCCESS: Vmlinux patch test passed
