函数名称：add_rules

函数原型：static void add_rules(struct ima_rule_entry *entries, int count, enum policy_rule_list policy_rule)

返回类型：void

参数：

类型参数名称
struct ima_rule_entry *entries
intcount
enum policy_rule_listpolicy_rule
577  i等于0
579  以i小于count循环
582  如果policy_rule按位与IMA_DEFAULT_POLICY则添加链表项
585  如果policy_rule按位与IMA_CUSTOM_POLICY则
586  entry等于kmemdup - duplicate region of memory*@src: memory region to duplicate*@len: memory region length*@gfp: GFP mask to use* Return: newly allocated copy of @src or %NULL in case of error
588  如果非entry则继续下一循环
591  添加链表项
593  如果action恒等于same as IMA_APPRAISE 则
594  temp_ima_appraise或等于ima_appraise_flag(func)
595  如果func恒等于POLICY_CHECK则temp_ima_appraise或等于IMA_APPRAISE_POLICY
