Specific embodiment
In order that the application the technical staff in the technical field is more clearly understood that the present invention, below in conjunction with the accompanying drawings,
Technical solution of the present invention is described in detail by specific embodiment.
Fig. 1, Fig. 2, Fig. 3 and Fig. 4 is refer to, the side of intermodule function interface in the acquisition program in the embodiment of the present application one
Method, comprises the steps：
Step 101, by one executable program of static scanning, generates intrinsic function static call IFSC relational files, outer
Portion's function call EFC relational file, and intrinsic function dynamic call IFDC shipping bills files.
In specific implementation process, the executable program is generated as follows：Source code is compiled first, is inserted into
The Hook Function of function call, the code that Hook Function can be previously implanted in a program by the step so as to can be in program
The extraction of IFDC information is completed during operation.
Wherein, to implement process as follows for the Hook Function of insertion function call：
One, in the setup code that the init sections insertion dynamic call relation of program is extracted；
Each executable file in described program, all includes a corresponding init section, and the init sections are described
Program is disposably run when loading.
Two, dynamic call relation is inserted at all of function entrance extract code.
According to the switch arranged in makefile during compiling, in specified file, the porch of all functions is added and is extracted
The code snippet that the kinematic function is called.Higher level's function call that current function can be extracted by running the code snippet goes out
Mouthful；And judge that higher level's function call is exported whether in IFDC shipping bills；And in the presence of dynamic call outlet,
Generate dynamic call record.
For step 101, in specific implementation process, specifically include：
One, the attribute information for characterizing each Function feature of each function in the executable program is extracted, such as：Letter
Several titles, type, address, size etc..In the Symbol sign fields of described program file, all functions and variable symbol is contained
Number information.One symbol is defined as follows：
Wherein, low 4 of st_info fields are st_type information, and the st_type values of all functional symbols are STT_
FUNC.Extract all functional symbols for meeting this feature then formation function inventory.
Then, according to the st_name being present in program in SHT_STRTAB sections, the title of the symbol is extracted.According to st_
Value simultaneously combines the load address that st_shndx corresponds to section, calculates the start address of symbol.Accorded with from st_size fields
Number size, i.e. the start address of the length of function, and associative function obtains the end address of function.The beginning of the function
Between address and end address, then it is the code interval of function.
Two, the reorientation section of the executable program is analyzed, the External Function Call EFC relational files are generated；
Wherein, the process for generating the External Function Call EFC relational files is specially：The executable program file exists
After compiling link, the symbolic reference in external dynamic storehouse can be directed to, corresponding relocation information is preserved in SHT_RELA sections.Described
SHT_RELA sections are address field or code segment in the executable program file, and the form of the relocation information is：
According to the r_offset, can calculate needs the address of reorientation in code segment, i.e. call the outside to move
The address of the instruction of state built-in function.The external symbol for calling is obtained according to the r_info, further inquires about st_ in symbol table
Symbols of the type for STT_UNDEF, can obtain the function name in external dynamic storehouse for calling, so as to form the executable program
EFC information.After completing the scanning to the executable program, can generate described under the executable program file catalogue
EFC relational files.
Three, the function code section of each function of the executable program is scanned, the function call for obtaining each function refers to
Order, specifically includes：
According to functional symbol inventory, the code interval of each function in described program, the code of each function is obtained
It is the machine code of each instruction of each function in interval, i.e. order code, the order code are generally accorded with by command operating
With groups of operands into.
For different CPU systems, instruction format be different, such as：Instruction format and AMD in the CPU systems of intel
CPU systems in instruction format be different；But for the same type of CPU systems, base instruction form is solid
Fixed, such as：Base instruction form in the CPU of the Pentium class of intel is fixed.
Determine the system of the CPU, and the instruction format according to corresponding CPU in the CPU systems, read in one by one described every
The order code of individual function, then extracts the operation code in the order code, and judges whether the instruction of the CPU is function
Call instruction.Wherein, the result of judgement includes two kinds of situations：
The first, the instruction of the CPU is not the function call instruction, then do not carry out what next step analytic function was called
Process；
Second, the instruction of the CPU is the function call instruction, then determine whether which kind of function call belonged to.
When determining whether to belong to which kind of function call, the operation code of the instruction by recognizing the CPU judges described
The method of calling of the call function that specifies in function call instruction, the method for calling of the call function specifically include two kinds：
The first, is called with register form；
Second, called with operand form.
When the function call mode that specifies in the function call instruction is register form, the function cannot pass through
Static analyzer Code obtaining object function information, needs to be extracted in follow-up program operation process.Accordingly, it would be desirable to
The call instruction outlet record of the undetermined object function, compiling when running for the executable program are embedded function
Use.After completing the scanning to the executable program, under the executable program file catalogue can generate the IFDC and go out
Mouth inventory file.
When the function call mode that specifies in the function call instruction is operand form, refer to from the function call
Make in code, extract corresponding operand, according to addressing system, be converted into corresponding object function absolute address.Then described
In functional symbol inventory, the object function title that calls is searched.
Outlet, object function is called to form an IFSC relation and recorded by described.Complete to the executable journey
After the scanning of sequence, the complete IFSC relational files can be generated under the executable program file catalogue.
Step 102, when the executable program is run, based on the IFDC shipping bills file, generates IFDC records
File.
In specific implementation process, when the executable program runs, first, the initialization work(embedded in init sections is executed
Can, the setup code of dynamic call relationship module is extracted, to obtain the IFDC shipping bills file, then, loading is described
IFDC shipping bills files, contain in the IFDC shipping bills file extraction in need function dynamic call relation,
Such as：Intrinsic function static call IFSC relational files, intrinsic function dynamic call IFDC relational files, External Function Call EFC
Relational file etc., executes the extraction code of the dynamic call relationship module in each function head, obtains each function
Higher level's function call exit address；
Wherein, higher level's function call exit address acquisition pattern of each function is specially：The dynamic call is closed
Be the extraction code of module from ra depositors, obtain current function higher level's function call outlet next instruction ground
Location, obtains higher level's function call exit address CP (the Calling Point) after correction.
Further, in the IFDC inventories, search the CP and whether there is.Wherein, the result of lookup includes two kinds of feelings
Condition：
The first, the CP is not present in the IFDC inventories, then it represents that the current function is called and need not be recorded,
Continue other instructions of the follow-up function of analysis；
Second, the CP is present in the IFDC inventories, then it represents that it is to need record that the current function is called
Dynamic call.
Now, in the corresponding function outlet entry of the IFDC inventories, object function list is searched.Wherein, lookup
As a result two kinds of situations are also included：
The first, current function then calls exit address respective function described in record in the object function list
IFDC information；
Second, current function then sets up a new IFDC relation not in the object function list, and record is described
The IFDC information of exit address respective function is called, and the IFDC information written document is added to the object function list
In.
The IFDC information of each function when program end of run, is extracted, is generated under the executable program catalogue
The IFDC log files.
Step 103, based on the EFC relational files, the IFSC relational files and IFDC log files, acquisition is described can

Calling).
Wherein, each FC packet contains multiple attribute informations, such as：Father's function name, call exit address, object function
Title, method of calling, father's function pair answer source file etc., the function interface relation between module for further analysis.
In concrete analysis, based on the function calling relationship table, the reality of intermodule in the executable program is obtained
Function interface relation；Wherein, detailed process is：Described parse complete function calling relationship table after, loading procedure internal mode
