\subsection*{Disassemble \emph{.NET} bytecode} |
|
||||||
|
|
||||||
The \emph{.NET} assembly is read using the \emph{Cecil} library |
|
||||||
and the class structure is created. Method bodies contain the |
|
||||||
disassembly of the IL bytecode. The debugging comment on the |
|
||||||
right indicates the stack behavior of the given instruction. |
|
||||||
This, of course, is not valid \CS code yet. |
|
||||||
|
|
||||||
\lstinputlisting[lastline=32] |
|
||||||
{./Evolution/01_Disassemble.cs} |
|
||||||
|
|
||||||
\newpage |
|
||||||
\subsection*{Start creating expressions} |
|
||||||
|
|
||||||
The bytecodes are converted to \CS expressions on individual basis. |
|
||||||
Only one bytecode is considered at a time and thus the expressions |
|
||||||
are completely independent. The resulting output is a valid \CS code |
|
||||||
which however does not compile since the dummy arguments \verb|arg1|, |
|
||||||
\verb|arg2|, etc\dots{} are never defined. Conditional and unconditional |
|
||||||
branches are converted to \verb|goto| goto statements. |
|
||||||

||||||

||||||
|
|
||||||
\newpage |
|
||||||
\subsection*{Data-flow analysis} |
|
||||||
|
|
||||||
The execution of the bytecode is simulated and the state of the stack is |
|
||||||
recorded for each position. We are interested in the number of |
|
||||||
elements on the stack as well as which instruction has pushed the |
|
||||||
individual elements on the stack. This information can then be used to eliminate |
|
||||||
the dummy \verb|arg1| arguments. Result of each instruction is stored |
|
||||||
in new temporary variable. When an instruction pops a stack value |
|
||||||
we look-up which instruction has allocated the value and use the temporary |
|
||||||
variable of the allocating instruction. |
|
||||||
This code compiles and works correctly. |

||||||

|
||||||
\subsection*{In-lineing expressions} |
|
||||||
|
|
||||||
Many of the temporary variables can be in-lined into the expressions in which |
|
||||||
they are used. This is in general non-trivial optimization, however it is |
|
||||||
simpler in this case since the temporary variables generated to store the |
|
||||||
stack values are guaranteed to be single static assignment variables (the |
|
||||||
variable is assigned only once during the push instruction and is used |
|
||||||
only once during the pop instruction). |
|
||||||
Having said that, we still need to check that doing the optimization is |
|
||||||
safe with regards to expression evaluation order and with regrads to branching. |

\subsection*{Finding basic blocks} |
|
||||||
|
|
||||||
The first step of reconstructing any high-level structures is the |
|
||||||
decomposition of the program into basic blocks. This is an easy |
|
||||||
algorithm to implement. |
|
||||||
|
|
||||||
I chose to use the following constraint for the output: |
|
||||||
``Each basic block starts with a label and is exited by an explicit |
|
||||||
\verb|goto| statement.'' |
|
||||||
Therefore except for the method entry, the order |
|
||||||
of the blocks is completely irrelevant. Any swapping of the basic |
|
||||||
blocks is not going change the semantics of the program in any way. |
|
||||||
|
|
||||||

|
||||||
|
|
||||||
\newpage |
|
||||||
\subsection*{Finding loops} |
|
||||||
|
|
||||||
The algorithm for finding loops is inspired by T1-T2 transformations. |
|
||||||
T1-T2 transformations are used to determine whether a graph is |
|
||||||
reducible or not. The core idea is that if a block of code has |
|
||||||
only one predecessor then the block of code can be merged |
|
||||||
with its predecessor to form a directed acyclic graph. Using this, |
|
||||||
loops will reduce to single self-referencing nodes. |
|
||||||
This also works for nested loops. |
|
||||||
|
|
||||||
Note that merely adding a loop does not change the program in any way -- |
|
||||||
the loop is completely redundant as far as control flow goes. |
|
||||||
The basic blocks still explicitly transfer control using \verb|goto| |
|
||||||
statements, so the control flow never reaches the loop. |
|
||||||
|
|
||||||
This is desirable property. It ensures that the program will run |
|
||||||
correctly. The order of basic blocks and their nesting within loops |
|
||||||
does not have any effect on program correctness. |
|
||||||
|
|
||||||
The only advantage of the loop is readability and that some \verb|goto| |
|
||||||
statements can be replaced by \verb|break| and \verb|continue| statements |
|
||||||
if they have the same semantics in the given context. |
|
||||||
|
|
||||||

|
||||||
|
|
||||||
\newpage |
|
||||||
\subsection*{Finding conditionals} |
|
||||||
|
|
||||||
The current algorithm for finding conditionals works as follows: |
|
||||||
First find a node that has two successors. Get all nodes accessible |
|
||||||
\emph{only} from the `true' branch -- these form the `true' body of |
|
||||||
the conditional. Similarly, all nodes accessible \emph{only} from the |
|
||||||
`false' branch form the `false' body. The rest of the nodes is |
|
||||||
not part of the conditional. |
|
||||||
|
|
||||||
Similarly as for the loops, adding a conditional does not have any |
|
||||||
effect on program correctness. |
|
||||||
|
|
||||||

|
||||||
|
|
||||||
\newpage |
|
||||||
\subsection*{Remove dead jumps} |
|
||||||
|
|
||||||
There are many \verb|goto| statements in the form: |
|
||||||
\begin{verbatim} |
|
||||||
goto BasicBlock_X; |
|
||||||
BasicBlock_X: |
|
||||||
\end{verbatim} |
|
||||||
These \verb|goto| statement can be removed. As a result of |
|
||||||
doing that, several labels will become dead; these can be |
|
||||||
removed as well. |
|
||||||
|
|
||||||

|
||||||

|
||||||
|
|
||||||
\newpage |
|
||||||
\subsection*{Reduce loops} |
|
||||||
|
|
||||||
It is common for loops to be preceded by a temporary variable |
|
||||||
initialization, start by evaluating a condition and finally |
|
||||||
end by doing an increment on a variable. We can look |
|
||||||
for these patterns and if they are found move the code |
|
||||||
to the \verb|for(;;)| part of the statement. |

||||||

\subsection*{Clean up} |

simplifying type names. |

\subsection*{Unexpected difficulties} |
|
||||||
|
|
||||||
The \emph{CodeDom} library that I have initially intended to use |
|
||||||
to output source code in arbitrary \emph{.NET} language has turned out to be |
|
||||||
quite incomplete. That is, since the library aims to be |
|
||||||
able to represent source code for any language, it has |
|
||||||
feature set limited to the lowest common denominator. |
|
||||||
Therefore, I have switched to \emph{NRefactory} library which |
|
||||||
is specifically designed with \CS and \emph{VB.NET} in mind. |
|
||||||
|
|
||||||
Using \emph{T1-T2} transformations for loop finding turned out to be |
|
||||||
a slightly more difficult since the algorithm is, after all, |
|
||||||
originally intended to produce a yes or no answer to whether the graph |
|
||||||
is reducible. However, it was not problematic to refactor |
|
||||||
the idea to suit a different purpose. |
|
||||||
|
|
||||||
\subsection*{Summary} |
|
||||||
|
|
||||||
The project tasks were performed in the planned order and |
|
||||||
the project is progressing according to the schedule. |
|
||||||
|
|
||||||
The quality of decompilation of the Quick-Sort algorithm is |
|
||||||
almost `as good as it gets' so I intend to look for some more |
|
||||||
complex assembly to tackle. |

\section*{Introduction and Description of the Work} |
|
||||||
The \emph{.NET Framework} is a general-purpose software development platform |
|
||||||
which is very similar to \emph{Java}. It includes extensive class library |
|
||||||
and, similarly to Java, is based on the virtual machine model. The executable |
|
||||||
code for a \emph{.NET} program is stored in a file called \emph{assembly} |
|
||||||
which consists of class metadata and a stack-based bytecode called Common |
|
||||||
Intermediate Language (\emph{CIL} or \emph{IL}). |
|
||||||
|
|
||||||
In general, any programming language can be compiled to \emph{.NET} and |
|
||||||
there are dozens of compilers that compile into \emph{CIL}. The most |
|
||||||
common language used for \emph{.NET} development is \emph{C\#}. |
|
||||||
|
|
||||||
The goal of this project is to decompile \emph{.NET} assemblies back into |
|
||||||
equivalent \emph{C\#} source code. Compared to decompilation of |
|
||||||
conventional assembly code, this task is hugely simplified by the |
|
||||||
presence of metadata in the \emph{.NET} assemblies. The metadata contains |
|
||||||
complete information about classes, methods and fields. The method bodies |
|
||||||
consist of stack-based \emph{IL} code which needs to be decompiled into |
|
||||||
higher-level \emph{C\#} statements. Data-flow analysis will need to be |
|
||||||
employed to transform the stack-based data model into one that uses |
|
||||||
temporary local variables and composition of expressions. Control-flow |
|
||||||
analysis will be used to recreate high level control structures like |
|
||||||
\verb|for| loops and conditional branching. |
|
||||||
|
|
||||||

|

\begin{itemize} |
|

\item{\textbf{My own machine}\\ |

|
||||||

|
||||||
\end{itemize} |
|
||||||
|
|
||||||
\newpage |
|
||||||
|
|
||||||
\section*{Starting Point} |
|
||||||
I plan to implement the project in \emph{C\#}. I have been using this |
|
||||||
language for over five years now and so I do not have to spend any time |
|
||||||
learning a new language. It also means that I will not be having any |
|
||||||
problems neither with the syntax of the language nor with any peculiar |
|
||||||
error messages produced by the compiler or by the runtime. |
|
||||||
|
|
||||||
I have written an integrated \emph{.NET} debugger for the |
|
||||||
\emph{SharpDevelop} IDE. During that I have obtained some basic knowledge |
|
||||||
about metadata and lower-level functionality in \emph{.NET}. I can read |
|
||||||
\emph{.NET} bytecode and, with the help of reference manual, I can write |
|
||||||
short programs in it. |
|
||||||
|
|
||||||
The metadata and bytecode needs to be read form the assembly files. |
|
||||||
I plan to use the \emph{Cecil} library for it. I am not familiar with this |
|
||||||
library, but I do not expect to have any difficulties with it. |
|
||||||
|
|
||||||
\section*{Substance and Structure of the Project} |
|
||||||
The project consists of the following major work items: |
|
||||||
\begin{enumerate} |
|
||||||
\newcommand{\milestone}[1]{\item \textbf{#1} \\} |
|
||||||
|
|
||||||
\milestone{Preliminary research} |
|
||||||
I will have to research the following topics: |
|
||||||
\begin{itemize} |
|
||||||
\item {\emph{Cecil} library} |
|
||||||
- \emph{Cecil} is the library which I will use for reading of the |
|
||||||
metadata. It will need to get familiar with its public API. |
|
||||||
Because it is open-source, it might be valuable to get some basic |
|
||||||
understanding of its source code as well. |
|
||||||
\item {\emph{CIL} bytecode} |
|
||||||
- The runtime of the \emph{.NET Framework} is described in |
|
||||||
ECMA-335 Standard: \emph{``CLI Specification -- Virtual Machine''} |
|
||||||
(556 pages). I will need to get familiar with this document since |
|
||||||
I will be using it as the main reference. I will be especially |
|
||||||
interested in \emph{Partition III -- CIL Instruction Set}. |
|
||||||
\item {Decompilation theory} - I will need to get familiar with the |
|
||||||
theory behind decompilation of programs. Cristina Cifuentes' |
|
||||||
PhD thesis \emph{``Reverse Compilation Techniques''} might prove as |
|
||||||
especially useful starting point. |
|
||||||
\end{itemize} |
|
||||||
|
|
||||||
The research of these topics should not be too extensive. I only indeed to |
|
||||||
get sufficient background knowledge in these areas and then return to the |
|
||||||
finner details when I needed them. |
|
||||||
|
|
||||||
\milestone{Create a skeleton of the code} |
|
||||||
It will be necessary to read the assembly metadata and create a \emph{C\#} |
|
||||||
source code that has the same classes, fields and methods. The method |
|
||||||
signatures have to match the ones in the assembly. At this point the method |
|
||||||
bodies can be left empty. |
|
||||||
|
|
||||||
\milestone{Read and disassemble \emph{.NET} bytecode} |
|
||||||
The next step is to read the bytecode for each method, disassemble it and |
|
||||||
output it as comments (for example, \verb|// IL_01: ldstr "Hello world"|). |
|
||||||
This will help me learn how to use the \emph{Cecil} library to read the |
|
||||||
bytecode and how to process it. I also expect that this output will be |
|
||||||
extremely helpful for debugging purposes later on. |
|
||||||
|
|
||||||
\milestone{Start creating r-value expressions} |
|
||||||
Ignoring the stack of the virtual machine, some bytecodes can be |
|
||||||
straightforwardly converted into expressions. For example: |
|
||||||
\begin{verbatim} |
|
||||||
ldstr "Hello world" - string "Hello world" |
|
||||||
ldnull - 'null' reference |
|
||||||
ldc.i4.0 - 4 byte integer of value 0 |
|
||||||
ldc.i4 123 - 4 byte integer of value 123 |
|
||||||
ldarg.0 - the first method argument |
|
||||||
ldloc.0 - the first local variable in the method |
|
||||||
\end{verbatim} |
|
||||||
|
|
||||||
The goal of this stage is to create \emph{C\#} expressions for several of |
|
||||||
the most important bytecodes. |
|
||||||
|
|
||||||
Function calls and arithmetic operations are also expressions, but at this |
|
||||||
stage I do not know their inputs and so I will have to use dummy values as |
|
||||||
their inputs. |
|
||||||
|
|
||||||
\milestone{Conditional and unconditional branching} |
|
||||||
There are several bytecodes that investigate one or two values on the top |
|
||||||
of stack and then, if a given condition is met, branch to different |
|
||||||
location. (\verb|br|, \verb|brfalse|, \verb|brtrue|, \verb|beq|, |
|
||||||
\verb|bge|, \verb|bgt|, etc...) |
|
||||||
|
|
||||||
The goal of this stage is to use \emph{C\#} labels and \verb|goto| |
|
||||||
statements to recreate this flow of control. (eg translate |
|
||||||
\verb|brfalse IL_02| to \verb|if (input == false) goto Label_02;|) |
|
||||||
|
|
||||||
As in the previous stage the inputs (ie the values at the top of stack) are |
|
||||||
still not know. |
|
||||||
|
|
||||||
\milestone{Simple data-flow analysis} |
|
||||||
This is where it begins to be difficult. Consider the code: |
|
||||||
\begin{verbatim} |
|
||||||
// Load "Hello, world!" on top of the stack |
|
||||||
IL_01: ldstr "Hello, world!" |
|
||||||
// Print the top of the stack to the console |
|
||||||
IL_02: call void [mscorlib]System.Console::WriteLine(string) |
|
||||||
\end{verbatim} |
|
||||||
Both of these are already decompiled as expressions, however the call |
|
||||||
has a dummy value as its argument. The goal of this stage is to perform |
|
||||||
as simple data-flow analysis as possible. The text "Hello, world!" must |
|
||||||
find its way to the method call. At this point it will probably be through |
|
||||||
one or even two temporary variables. For example: |
|
||||||
\begin{verbatim} |
|
||||||
String il_01_expression = "Hello, world!"; |
|
||||||
String il_02_argument_1 = il_01_expression; |
|
||||||
System.Console.WriteLine(il_02_argument_1); |
|
||||||
\end{verbatim} |
|
||||||
The most difficult part will be handling of control flow. Different values |
|
||||||
can be on stack depending on which branch of code was executed. At this |
|
||||||
stage it will be necessary to create and analyse control flow graph. As a |
|
||||||
result of this stage, many temporary variables might be introduced to the |
|
||||||
code. |
|
||||||
|
|
||||||
\milestone{Round-trip quick-sort algorithm} |
|
||||||
At this point very simple applications should probably successfully |
|
||||||
decompile and compile again (round-trip). |
|
||||||
|
|
||||||
The goal of this stage is to fix bugs and to add features so that simple |
|
||||||
algorithm like quick-sort can be successfully round-tripped without need to |
|
||||||
manually change the produced \emph{C\#} source code. At this point there is |
|
||||||
no restriction on the aesthetics of the source code. The only requirement |
|
||||||
is that it does compile. |
|
||||||
|
|
||||||
There are many features of \emph{.NET} that I do not plan to support at |
|
||||||
this point. For example, boxing \& unboxing, casting, generics and |
|
||||||
exception handling. In general, all non-essential features are excluded. |
|
||||||
|
|
||||||
\milestone{Further data-flow analysis} |
|
||||||
Employ more advanced data-flow analysis to simplify the generated \emph{C\#} |
|
||||||
code. Many temporary variables can be probably removed, relocated or |
|
||||||
renamed according to their use. |
|
||||||
|
|
||||||
\emph{[This task has variable scope and if the project starts falling behind |
|
||||||
schedule, simpler algorithms can be employed and vice versa.]} |
|
||||||
|
|
||||||
\milestone{Control-flow analysis} |
|
||||||
The goal of this stage is to use control-flow analysis to regenerate |
|
||||||
high-level structures like \verb|if| statements and \verb|for| loops. |
|
||||||
It will not be possible to eliminated all \verb|goto| statements, but they |
|
||||||
should be avoided whenever possible. |
|
||||||
|
|
||||||
\emph{[This task has variable scope and if the project starts falling behind |
|
||||||
schedule, simpler algorithms can be employed and vice versa.]} |
|
||||||
|
|
||||||
\milestone{Assembly resources} |
|
||||||
\emph{.NET} assemblies can have files embed in them. These files can then |
|
||||||
be accessed at runtime and thus the programs might require them. |
|
||||||
|
|
||||||
The goal is to extract the resources so that they can be included during |
|
||||||
the recompilation process. |
|
||||||
|
|
||||||
\emph{[Optional. This is an optional goal which will be done only if the |
|
||||||
project development goes much better then originally anticipated.]} |
|
||||||
|
|
||||||
\milestone{Advanced features} |
|
||||||
Add commonly used features which where ignored so far - for example, |
|
||||||
boxing \& unboxing, casting, generics and exception handling. |
|
||||||
|
|
||||||
\emph{[Optional. This is an optional goal which will be done only if the |
|
||||||
project development goes much better then originally anticipated.]} |
|
||||||
|
|
||||||
\milestone{Round-trip Mono} |
|
||||||
The ultimate goal of this project is to be able to round-trip any |
|
||||||
\emph{.NET} assembly. This means that for any given assembly the |
|
||||||
Decompiler should produce \emph{C\#} source code which is valid (does |
|
||||||
compile again without error). Even more importantly, the program produced |
|
||||||
by the compilation of the source code should be semantically same as the |
|
||||||
original one. Since the bytecode will in general differ, this condition is |
|
||||||
difficult to verify. One way to check that the Decompiler preserves the |
|
||||||
meaning of programs is to simply try it. |
|
||||||
|
|
||||||
\emph{Mono} is open-source reimplantation of the \emph{.NET Framework}. |
|
||||||
The major part of it are the \emph{.NET} class libraries which can be |
|
||||||
used for testing of the Decompiler. The project is open-source and so if |
|
||||||
any decompilation problems occur, it is possible to investigate the |
|
||||||
source code of these libraries. Furthermore, the libraries come with |
|
||||||
extensive unit testing suite so it is possible to verify that the |
|
||||||
round-tripped libraries are not broken. |
|
||||||
|
|
||||||
The goal of this final stage is to successfully round-trip all \emph{Mono} |
|
||||||
libraries and pass the unit tests. This would probably involve enormous |
|
||||||
amount of bugfixing, investigation and handling of corner cases. All |
|
||||||
remaining \emph{.NET} features would have to be implemented. |
|
||||||
|
|
||||||
\emph{[Optional. This last stage is huge and impossible to be finished |
|
||||||
within the time frame of Part II project. If all goes well, I expect |
|
||||||
that it will take at least one more year for the project to mature to |
|
||||||
this point.]} |
|
||||||
|
|
||||||
\milestone{Write the dissertation} |
|
||||||
The last and most important piece of work is to write the dissertation. |
|
||||||
Being a non-native English speaker, I expect this to take considerable |
|
||||||
amount of time. I plan to spend the last seven weeks of project time |
|
||||||
on it. This includes the end of Lent Term and the whole Easter vacation. |
|
||||||
I plan to have the dissertation finished by the start of Easter term. |

||||||
The Decompiler should successfully round-trip a quick-sort algorithm |
|
||||||
(or any algorithm of comparable complexity). |
|
||||||
That is, when an assembly containing the algorithm is |
|
||||||
decompiled, the produced \emph{C\#} source code should be both |
|
||||||
syntactically and semantically correct. The bytecode produced |
|
||||||
by compilation of the generated source code is not expected to be |
|
||||||
identical to the original one, but it is expected to be equivalent. |
|
||||||
That is, the binary may be different but it still needs to be a correct |
|
||||||
implementation of the algorithm. |
|
||||||
|
|
||||||
To achieve this the Decompiler will need to have the following features: |
|
||||||
\begin{itemize} |
|
||||||
\item Handle integers and integer arithmetic |
|
||||||
\item Create and be able to use integer arrays |
|
||||||
\item Branching must be successfully decompiled |
|
||||||
\item Several methods can be defined |
|
||||||
\item Methods can have arguments and return values |
|
||||||
\item Methods can be called recursively |
|
||||||
\item Integer command line arguments can be read and parsed |
|
||||||
\item Text can be outputted to the standard console output |
|
||||||
\end{itemize} |
|
||||||
|
|
||||||
See the following page for a \emph{C\#} implementation of a quick-sort |
|
||||||
algorithm which will be used to demonstrate successful implementation |
|
||||||
of these features. |
|
||||||
|
|
||||||
I plan to achieve the success criteria by the progress report dead-line |
|
||||||
and then spend the rest of the time available by increasing the quality |
|
||||||
of the generated source code (ie ``Further data-flow analysis'' and |
|
||||||
``Control-flow analysis''). |
