ELF File, elf The ELF file format is a development standard. executable files of Various UNIX systems use the ELF format, which has three different types: Relocated target file Executable files Shared Library Now, let's analyze the format of the target file max. o generated after compilation and the file max gener

During embedded development, we compile a *. s file and finally generate the binfile. The compilation command is roughly as follows: Cc = arm-softfloat-Linux-GNU-gcc LD = arm-softfloat-Linux-GNU-LD Objcopy = arm-softfloat-Linux-GNU-objcopy $ (CC)-G $ (cflag)-C boot. s # first generate the boot. s file to boot. o $ (LD)-g-bstatic-T $ (ldfile)-ttext 0x12345600 boot. O -- start-group-map boot. map-O boot. elf # restart boot. O generate boot.

HP's Shadow Elves series of games I believe that we will not be unfamiliar, this model of the main price-performance game this series of models long occupied Jingdong sales, in this year's launch of the 2-generation model for the Omen series, while the body tones to red, and will be upgraded to GTX 960M. Now the Shadow Elf 2-Wizard Green Edition has also been listed, not only return to a generation of green tones, while in addition to the GTX 960M ver

The ELF (executable and linkable format) executes the connection file format, which is a more complex file format, but is widely used. Compared to other executable files under Linux (A.OUT,COF), its definition of the section and its support for the GNU tool chain make it flexible enough to preserve the system-related information that enables it to support cross compilation and cross linking on different platforms, and is highly portable. It also suppo

The executable and linking format has been a popular topic lately, as people ask why the Kernel configuration script asks whether or not to configure loading elf executables. since elf will eventually be the common object file format for Linux binaries, it is appropriate to document it a bit. last month, Eric introduced us to elf, and this month, he gives us a gu

Unix elf File Format and virus analysis ★IntroductionThis article describes the Unix virus mechanism, implementation, and ELF file format. This article briefly describes the Unix virus detection and anti-detection technologies, and provides some examples under the Linux/i386 architecture. It requires some preliminary Unix programming experience to be able to understand the Assembly Language in Linux/i386.

Interpreting elf files with instances-Reading Notes (1)Bkbll (bkbll@cnhonker.net, bkbll@tom.com)2003/09/09I. PrerequisitesThere are many articles on the Internet that describe the formats and loading processes of ELF files. I think these articles are useful:1. breadbox's Http://elfhack.whitecell.org/mydocs/elf.txt.English: http://elfhack.whitecell.org/mydocs/ELF_chinese.txt2. alert7's Http://elfhack.whitece

The code, connection information, and annotations in the ELF file are stored in sections (section) and contain a Header table (section header). For each section, there is a table entry in the section Header table (section Header table entry) Corresponding to this, the table entry records some information about the section, such as its location information in the file and the section The byte length information. I.

Introduction to the elf file format2014-11-02 The elf represents executable and linkable forma, a file format used for executable files, destination files, and libraries, similar to the PE file format under Windows. The ELF format was developed and published by the UNIX Systems Lab as a ABI (Application Binary Interface) and was already a standard form of Linux.

Talking about the debugging of the shelled ELF (that is, the android so file), elfandroid This article only discusses how to debug the shelled ELF file, including the use of Debugging techniques and solutions to possible problems during debugging, DEX does not contain how to restore the reinforcement. This article will take a shell program and a reinforcement as the target. 1. Introduction to

(Reprinted) GCC and OBJ files, dynamic link files and elf files --------------------------------------------------------------------------------1. OBJ file Programmers write programs by writing a binary file. If we declare a variable char C, that is, the Declaration requires an 8-bit space, then we need to declare to the system that the 8-bit space is reserved. How can we do this? It is to compile a special binary file-OBJ file. The execution file obt

This article mainlyThis section briefly introduces and summarizes the implementation of Win32 PE and Linux elf shelling programs on the X86 platform.The program provides clues, in which the program source code is open-source. If you are interested, you can continue to improve the program. PS: some of them haven't been touched

Android reverse journey --- explanation of the SO (ELF) File Format1. Preface Starting from today, we have officially started our Android reverse journey. We should be familiar with reverse engineering knowledge. The reverse engineering field is a challenging and mysterious field. As an Android developer, everyone wants to explore this field, because once you crack other people's content, your sense of accomplishment will surely burst. But on the cont

Recently studied the elf file format, found that a lot of information written more cumbersome, it may be a serious blow to the enthusiasm of the learners, I put my research results and share with you, I hope that my descriptive narrative can be concise.First, the basic knowledgeElf is a file format for storing Linux programs. What information does it have inside? Probably contains the prepared computer instructions, data, the computer when needed to r
