Мобильная версияI know libc.so is executeable because:
- libc.so has a entry point function.
- There is .interp section in libc.so.
And I refered many documents, .interp section is considered to be necessary for an executable so. When I use call libonload.so, I can execute libonload.so, but readelf shows no .interp section. I don't know how it works. I run libonload.so, the result is:
