通用的讲,我需要将某些函数的调用重定向到我们自己定义的替代函数中来,这样的替代函数就叫做包装函数(wrapper function)。对malloc这个具体的场景来说我们不仅需要hack函数的调用,还要获取原本glibc定义的“real malloc”的句柄(函数指针)以使程序正常运行下去,当然如果这一切可以在不需要重新编译软件的前提下完成就更好了...
/* blk0() and blk() perform the initial expand. *//* I got the idea of expanding during the round function from SSLeay */#ifdefined(LITTLE_ENDIAN)#defineblk0(i)\(block->l[i]=(rol(block->l[i],24)&0xFF00FF00)|\(rol(block->l[i],8)&0x00FF00FF))#elifdefined(BIG_ENDIAN)...
先看下代码 /* blk0() and blk() perform the initial expand. *//* I got the idea of expanding during the round function from SSLeay */#if defined(LITTLE_ENDIAN)#define blk0(i) \(block->l[i] = (rol(block->l[i], 24) & 0xFF00FF00) | \(rol(block->l[i], 8) & 0x00FF...
c/c++语言具备一个不同于其他编程语言的的特性,即支持可变参数。 例如C库中的printf,scanf等函数,都支持输入数量不定的参数。printf函数原型为 int printf(const char *format, …); printf("hello world");///< 1个参数printf("%d", a);///< 2个参数printf("%d, %d", a, b);///< 3个参数 测...
Timsort - A templated stable sorting function which outperforms quicksort-based algorithms including std::sort, for reversed or semi-sorted data. [MIT] Indiesort - A sort wrapper which enables the use of std::sort (& other random-access sort functions) with non-random-access containers, and...
</FunctionName> </FunctionIdentifier> <OutArguments>0</OutArguments> </DataflowCleanseRule> 规则表示clean_data函数执行后其第 0 个参数就是干净的(不再是污点值),此时就可以把外部数据被过滤的场景从查询结果中剔除掉了。 此时的扫描还会漏报call_our_wrapper_system_custom_memcpy_example,因为其中使用了cust...

第一种方案的查询如下,其实就是把our_wrapper_system也考虑进sink点 import cpp import semmle.code.cpp.dataflow.TaintTracking predicate setSystemSink(FunctionCall fc, Expr e) { fc.getTarget().getName().matches("system") and fc.getArgument(0) = e ...
You need to write a C function wrapper to interface with C++ code. To test models that include C Caller blocks, see Test Integrated C Code (Simulink Test). Note If a model has custom code, after the model is updated or run, the slprj folder may be locked due to the loaded custom ...
