Section type: sh_type == SHT_STRTAB.
Common name: "section header string table".
The section name .shstrtab is reserved. The standard says:
This section holds section names.
This section gets pointed to by the e_shstrnd field of the ELF header itself.
String indexes of this section are are pointed to by the sh_name field of section headers, which denote strings.
This section does not have SHF_ALLOC marked, so it will not appear on the executing program.
readelf -x .shstrtab hello_world.o
outputs:
Hex dump of section '.shstrtab':
  0x00000000 002e6461 7461002e 74657874 002e7368 ..data..text..sh
  0x00000010 73747274 6162002e 73796d74 6162002e strtab..symtab..
  0x00000020 73747274 6162002e 72656c61 2e746578 strtab..rela.tex
  0x00000030 7400                                t.
The data in this section has a fixed format: www.sco.com/developers/gabi/2003-12-17/ch4.strtab.html
If we look at the names of other sections, we see that they all contain numbers, e.g. the .text section is number 7.
Then each string ends when the first NUL character is found, e.g. character 12 is \0 just after .text\0.
