  • X86-64 Calling Conventions
    CSE 351: The Hardware/Software Interface Section 4 Procedure calls Procedure calls In x86 assembly, values are passed to function calls on the stack Perks: Concise, easy to remember Drawbacks: Always requires memory accesses In x86-64 assembly, values are passed to function calls in registers Perks: Less wasted space, faster Drawbacks: Potentially requires a lot of register manipulation 2/23/2014 2 x86 calling conventions Simply push arguments onto the stack in order, then “call” the function! Suppose we define the following function: int sum(int a, int b) { return a + b; } (See also sum.c from the provided code) 2/23/2014 3 x86 calling conventions int sum(int a, int b) { return a + b; } In assembly, we have something like this: sum: pushl %ebp # Save base pointer movl %esp, %ebp # Save stack pointer movl 12(%ebp), %eax # Load b movl 8(%ebp), %edx # Load a addl %edx, %eax # Compute a + b popl %ebp # Restore base pointer ret # Return 2/23/2014 4 x86 calling conventions What is happening with %ebp and %esp? pushl %ebp The base pointer %ebp is the address of the caller, which is the location to which “ret” returns. The function pushes it into the stack so that it won’t be overwritten movl %esp, %ebp Functions often shift the stack pointer to allocate temporary stack space, so this instruction makes a backup of the original location. In the body of the function, %ebp is now the original start of the stack ret When sum() returns, execution picks up at the stored base pointer address.

Damien VERGNAUD Examinateur Abstract Bitslicing is a technique commonly used in cryptography to implement high-throughput parallel and constant-time symmetric primitives. However, writing, optimizing and pro- tecting bitsliced implementations by hand are tedious tasks, requiring knowledge in cryptography, CPU microarchitectures and side-channel attacks. The resulting programs tend to be hard to maintain due to their high complexity.

  • Differentiating Code from Data in X86 Binaries
    Differentiating Code from Data in x86 Binaries Richard Wartell, Yan Zhou, Kevin W. Hamlen, Murat Kantarcioglu, and Bhavani Thuraisingham Computer Science Department, University of Texas at Dallas, Richardson, TX 75080 {rhw072000,yan.zhou2,hamlen,muratk,bhavani.thuraisingham}@utdallas.edu Abstract. Robust, static disassembly is an important part of achieving high coverage for many binary code analyses, such as reverse engineering, malware analysis, reference monitor in-lining, and software fault isola- tion. However, one of the major difficulties current disassemblers face is differentiating code from data when they are interleaved. This paper presents a machine learning-based disassembly algorithm that segments an x86 binary into subsequences of bytes and then classifies each subse- quence as code or data. The algorithm builds a language model from a set of pre-tagged binaries using a statistical data compression technique. It sequentially scans a new binary executable and sets a breaking point at each potential code-to-code and code-to-data/data-to-code transition. The classification of each segment as code or data is based on the min- imum cross-entropy. Experimental results are presented to demonstrate the effectiveness of the algorithm. Keywords: statistical data compression, segmentation, classification, x86 binary disassembly. 1 Introduction Disassemblers transform machine code into human-readable assembly code. For some x86 executables, this can be a daunting task in practice. Unlike Java byte- code and RISC binary formats, which separate code and data into separate sections or use fixed-length instruction encodings, x86 permits interleaving of code and static data within a section and uses variable-length, unaligned in- struction encodings.

  • 8. Procedures
    8. Procedures X86 Assembly Language Programming for the PC 71 Stack Operation A stack is a region of memory used for temporary storage of information. Memory space should be allocated for stack by the programmer. The last value placed on the stack is the 1st to be taken off. This is called LIFO (Last In, First Out) queue. Values placed on the stack are stored from the highest memory location down to the lowest memory location. SS is used as a segment register for address calculation together with SP. X86 Assembly Language Programming for the PC 72 Stack Instructions Name Mnemonic and Description Format Push onto push src (sp)(sp)-2 Stack ((sp))(src) Pop from pop dst (dst)((sp)) Stack (sp)(sp)+2 Push Flags pushf (sp)(sp)-2 ((sp))(psw) Pop Flags popf (psw)((sp)) (sp)(sp)+2 Flags: Only affected by the popf instruction. Addressing Modes: src & dst should be Words and cannot be immediate. dst cannot be the ip or cs register.

Syntax: ProcedureName PROC Attribute . ProcedureName ENDP ProcedureName may be any valid identifier. Attribute is NEAR if the Procedure is in the same code segment as the calling program; or FAR if in a different code segment.

  • 1. (5 Points) for the Following, Check T If the Statement Is True, Or F If the Statement Is False
    CS-220 Spring 2019 Test 2 Version Practice Apr. 22, 2019 Name: 1. (5 points) For the following, Check T if the statement is true, or F if the statement is false. (a) T F : The Gnu Debugger (gdb) works at the C level. If you did not compile with the -g option, the Gnu Debugger is virtually useless. (b) T F : If the zero flag (ZF) is true, then the instruction "jne LINE3" will branch to LINE3. (c) T F : In X86-64 assembler, the memory referenced by -0x1C(%rbp) is the same as the memory referenced by -0x1C(%rbp,%rax,16) if the %rax register contains a zero. (d) T F : The x86/64 "push" instruction always decreases the value in the %rsp register. The "pop" isntruction always increases the value in the %rsp register. (e) T F : After executing a conditional jump instruction, the %rip register always points at the instruction after the jump instruction. (f) T F : In the X86-64 ISA instruction processing cycle, there are four phases of the cycle which potentially read or write from memory: the "fetch instruction" phase, the "evaluate address" phase, the "fetch operands" phase, and the "store results" phase. (g) T F : It is important that an older version of an ISA support everyting in a newer version of the same ISA so that new software can be run on both old and new hardware. (h) T F : The concept of dividing registers into caller-saved registers and callee-saved registers makes the resulting code much more efficient because we never have to save and restore registers that don't need to be saved and restored, and most of the time, no registers need to be saved or restored.
