C++ (Cpp) enable_wp Examples

Example #1

File: symbol_resolver.c Project: 07151129/ThreadBinder

/*
 * enable/disable kernel memory write protection
 */
kern_return_t enable_kernel_write(boolean_t enable) {
	kern_return_t res = KERN_SUCCESS;
	if (enable) __asm__ volatile("cli"); // disable interrupts
	if (enable_wp(!enable) != KERN_SUCCESS) {
		enable = FALSE;
		res = KERN_FAILURE;
	}
	if (!enable) __asm__ volatile("sti"); // enable interrupts
	return res;
}

Example #2

{
  disable_wp();
  UNHOOK_SYS_CALL_TABLE(open);
  UNHOOK_SYS_CALL_TABLE(unlink);
  UNHOOK_SYS_CALL_TABLE(unlinkat);
  enable_wp();

  fm_alert("%s\n", "Farewell the World!");

  return;
}

Example #3

  disable_wp();
  HOOK_SYS_CALL_TABLE(open);
  HOOK_SYS_CALL_TABLE(unlink);

  enable_wp();

  return 0;
}
