readelf
用于显示elf格式文件的信息 ## 补充说明 **readelf命令** 用来显示一个或者多个elf格式的目标文件的信息,可以通过它的选项来控制显示哪些信息。这里的elf-file(s)就表示那些被检查的文件。可以支持32位,64位的elf格式文件,也支持包含elf文件的文档(这里一般指的是使用ar命令将一些elf文件打包之后生成的例如lib*.a之类的“静态库”文件)。 这个程序和objdump提供的功能类似,但是它显示的信息更为具体,并且它不依赖BFD库(BFD库是一个GNU项目,它的目标就是希望通过一种统一的接口来处理不同的目标文件),所以即使BFD库有什么bug存在的话也不会影响到readelf程序。 运行readelf的时候,除了-v和-H之外,其它的选项必须有一个被指定。 ### ELF文件类型 **种类型的ELF文件:** 1. 可重定位文件:用户和其他目标文件一起创建可执行文件或者共享目标文件,例如lib*.a文件。 2. 可执行文件:用于生成进程映像,载入内存执行,例如编译好的可执行文件a.out。 3. 共享目标文件:用于和其他共享目标文件或者可重定位文件一起生成elf目标文件或者和执行文件一起创建进程映像,例如lib*.so文件。 **ELF文件作用:** ELF文件参与程序的连接(建立一个程序)和程序的执行(运行一个程序),所以可以从不同的角度来看待elf格式的文件: 1. 如果用于编译和链接(可重定位文件),则编译器和链接器将把elf文件看作是节头表描述的节的集合,程序头表可选。 2. 如果用于加载执行(可执行文件),则加载器则将把elf文件看作是程序头表描述的段的集合,一个段可能包含多个节,节头表可选。 3. 如果是共享文件,则两者都含有。 **ELF文件总体组成:** elf文件头描述elf文件的总体信息。包括:系统相关,类型相关,加载相关,链接相关。 * 系统相关表示:elf文件标识的魔术数,以及硬件和平台等相关信息,增加了elf文件的移植性,使交叉编译成为可能。 * 类型相关就是前面说的那个类型。 * 加载相关:包括程序头表相关信息。 * 链接相关:节头表相关信息。 ### 选项 ```shell -a --all 显示全部信息,等价于 -h -l -S -s -r -d -V -A -I. -h --file-header 显示elf文件开始的文件头信息. -l --program-headers --segments 显示程序头(段头)信息(如果有的话)。 -S --section-headers --sections 显示节头信息(如果有的话)。 -g --section-groups 显示节组信息(如果有的话)。 -t --section-details 显示节的详细信息(-S的)。 -s --syms --symbols 显示符号表段中的项(如果有的话)。 -e --headers 显示全部头信息,等价于: -h -l -S -n --notes 显示note段(内核注释)的信息。 -r --relocs 显示可重定位段的信息。 -u --unwind 显示unwind段信息。当前只支持IA64 ELF的unwind段信息。 -d --dynamic 显示动态段的信息。 -V --version-info 显示版本段的信息。 -A --arch-specific 显示CPU构架信息。 -D --use-dynamic 使用动态段中的符号表显示符号,而不是使用符号段。 -x <number or name> --hex-dump=<number or name> 以16进制方式显示指定段内内容。number指定段表中段的索引,或字符串指定文件中的段名。 -w[liaprmfFsoR] or --debug-dump[=line,=info,=abbrev,=pubnames,=aranges,=macro,=frames,=frames-interp,=str,=loc,=Ranges] 显示调试段中指定的内容。 -I --histogram 显示符号的时候,显示bucket list长度的柱状图。 -v --version 显示readelf的版本信息。 -H --help 显示readelf所支持的命令行选项。 -W --wide 宽行输出。 @file 可以将选项集中到一个文件中,然后使用这个@file选项载入。 ``` ### 实例 先给出如下例子: **1.对于可执行文件形式的elf格式文件:** 1)查看可执行程序的源代码如下: ```shell root@localhost [test]$ cat main.cpp #include <iostream> using std::cout; using std::endl; void my_print(); int main(int argc, char *argv[]) { my_print(); cout<<"hello!"<<endl; return 0; } void my_print() { cout<<"print!"<<endl; } ``` 2)编译如下: ```shell [root@localhost test]$ g++ main.cpp -o main [root@localhost test]$ g++ -g main.cpp -o main.debug ``` 3)编译之后,查看生成的文件: ```shell [root@localhost test]$ ls -l 总计 64 -rwxr-xr-x 1 quietheart quietheart 6700 07-07 18:04 main -rw-r--r-- 1 quietheart quietheart 201 07-07 18:02 main.cpp -rwxr-xr-x 1 quietheart quietheart 38932 07-07 18:04 main.debug ``` 这里,main.debug是带有调试信息的可执行文件,main是一般的可执行文件。 **2.对于库文件形式的elf格式文件:** 1)查看库的源代码如下: ```shell //myfile.h #ifndef __MYFILE_H #define __MYFILE_H void printInfo(); #endif //myfile.cpp #include "myfile.h" #include <iostream> using std::cout; using std::endl; void printInfo() { cout<<"hello"<<endl; } ``` 2)编译如下: ```shell [root@localhost test]$ g++ -c myfile.cpp [root@localhost test]$ g++ -shared -fPCI -o libmy.so myfile.o [root@localhost test]$ ar -r libmy.a myfile.o ar: creating libmy.a ``` 3)编译之后,查看生成的文件: [root@localhost test]$ ls -l 总计 44 ```shell -rw-r--r-- 1 quietheart quietheart 2154 07-08 16:14 libmy.a -rwxr-xr-x 1 quietheart quietheart 5707 07-08 16:08 libmy.so -rwxr-xr-x 1 quietheart quietheart 117 07-08 16:06 myfile.cpp -rwxr-xr-x 1 quietheart quietheart 63 07-08 16:08 myfile.h -rw-r--r-- 1 quietheart quietheart 2004 07-08 16:08 myfile.o libmy.a libmy.so myfile.cpp myfile.h myfile.o ``` 这里,分别生成目标文件myfile.o,共享库文件libmy.so,和静态库文件libmy.a。 基于以上可执行文件和库,这里给出一些常用的命令。 **读取可执行文件形式的elf文件头信息:** ```shell [root@localhost test]$ readelf -h main ELF Header: Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 type: exec (Executable file) Machine: Intel 80386 Version: 0x1 Entry point address: 0x8048580 Start of program headers: 52 (bytes into file) Start of section headers: 3232 (bytes into file) Flags: 0x0 Size of this header: 52 (bytes) Size of program headers: 32 (bytes) Number of program headers: 8 Size of section headers: 40 (bytes) Number of section headers: 29 Section header string table index: 26 ``` 这里,可见可执行文件的elf文件,其类型为EXEC(可执行文件)。另外,含调试信息的"main.debug"和不含调试信息的"main"除了一些大小信息之外,其内容是一样的。并且由此可见文件的体系结构为Intel 80386。 **读取目标文件形式的elf文件头信息:** ```shell [root@localhost test]$ readelf -h myfile.o ELF Header:

of program headers: 0 (bytes) Number of program headers: 0 Size of section headers: 40 (bytes) Number of section headers: 15 Section header string table index: 12 ``` 这里,可见目标文件的elf文件,其类型为REL(可重定位文件)。 **读取静态库文件形式的elf文件头信息:** ```shell [root@localhost test]$ readelf -h libmy.a File: libmy.a(myfile.o) ELF Header: Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement,

Header: Magic: 7f 45 4c 46 01 01 01 00 00 00 00 00 00 00 00 00 Class: ELF32 Data: 2's complement, little endian Version: 1 (current) OS/ABI: UNIX - System V ABI Version: 0 Type: DYN (Shared object

(bytes) Size of program headers: 32 (bytes) Number of program headers: 5 Size of section headers: 40 (bytes) Number of section headers: 27 Section header string table index: 24 ``` 这里,可见动态库文件的elf文件,其类型为DYN(共享目标文件)。 **查看可执行的elf文件程序头表信息:** ```shell [root@localhost test]$ readelf -l main Elf file type is EXEC (Executable file) Entry point 0x8048580 There are 8 program headers,
