函数名称:mulate_umip_insn() - Emulate UMIP instructions and return dummy values*@insn: Instruction structure with operands*@umip_inst: A constant indicating the instruction to emulate*@data: Buffer into which the dummy result is stored*@data_size: Size of the
函数原型:static int emulate_umip_insn(struct insn *insn, int umip_inst, unsigned char *data, int *data_size, bool x86_64)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct insn * | insn | |
int | umip_inst | |
unsigned char * | data | |
int * | data_size | |
bool | x86_64 |
220 | dummy_limit等于0 |
223 | 如果X86_MODRM_MOD(value)恒等于3则返回:负EINVAL |
242 | memcpy(data + 2, & dummy_base_addr, * data_size) |
245 | memcpy(data, & dummy_limit, UMIP_GDT_IDT_LIMIT_SIZE) |
248 | dummy_value等于CR0_STATE |
258 | 如果X86_MODRM_MOD(value)恒等于3则data_size等于opnd_bytes |
260 | 否则data_size等于2 |
263 | memcpy(data, & dummy_value, * data_size) |
265 | 否则 |
266 | 返回:负EINVAL |
