Where is the symbol table in Elf?
You can find where a symbol is placed in an executable ELF image. To find where a symbol is placed in an ELF image file, use the –text -s -v options to view the symbol table and detailed information on each segment and section header, for example: The symbol table identifies the section where the symbol is placed.
Where is the symbol table defined?
Symbol table is an important data structure created and maintained by compilers in order to store information about the occurrence of various entities such as variable names, function names, objects, classes, interfaces, etc. Symbol table is used by both the analysis and the synthesis parts of a compiler.
Where to find binary symbol table in Elf?
Let’s build it and examine the binary: It lists the symbol in the .data section of the ELF file. Page 20 of the ELF documentation defines the .data section as:
Where are the symbols in Elf-unix.data?
The .data section contains the data itself, i.e. the four bytes which hold the int value 5. The .symtab section contains the symbols, i.e. the names given to various parts of the binary; the var_global_init symbol name points to the four bytes of storage in the .data section.
What does St _ info mean in ELF format?
For the symbol highlighted here we can see the following: st_size is set to 0 which means it won’t take up any space in the binary during execution and probably doesn’t define a variable. st_info is set to 0x03 which means the symbol type is SECTION which means its a symbol associated to a section.
Where to find relocations in the ELF format?
Suffice it to say “relocations” will be found in the Relocation Tables and the symbols these refer to will be found in the ELFs Symbol Tables – I should mention also there is more than one symbol table and more than one relocation table, for nothing else than efficiency and extended capability in configuring symbol resolution.
