C program new segment declaration

Question

i've this simple code test code:

#include <Windows.h>
#include <stdio.h>

/* Declare new sections to store encrypted code and shellcode data */
#pragma section(".code", execute, read, write)
#pragma comment(linker,"/SECTION:.code,ERW")

// From here executable code will go in .code section
#pragma code_seg(".code")


int test()
{
    printf("prova");
    return 0;
}

// .stub SECTION
#pragma section(".stub", execute, read, write)
#pragma code_seg(".stub")

int main(int argc, char *argv[]){
    test(); /* Call function which executes shellcode now that it is decrypted */
    return 0;
}

Can anyone tell me why if i dump this file i only got this default section:

• .data
• .rdata
• .reloc
• .rsrc
• .stub
• .text

The .code segment it's not generated. I think I used to do like this in some previuos project, am i doing something wrong?

-- Further tests --

• Dumping the .obj file the .code section is shown.
• .stub gets showed dumping .exe or .obj
• removing #pragma comment(linker,"/SECTION:.code,ERW") did not work
• adding #pragma comment(linker,"/SECTION:.stub,ERW") didn't change dumpbin result on .exe, .stub still showing
• change the name from .code to .somethingelse didn't work either, same result

Answer 1

Using the following directives i was able to confine all the code/variable/costant into the .code segment which was visible using the dumbin command.

#pragma section(".code", execute, read)
#pragma section(".codedata", read, write)
#pragma comment(linker,"/SECTION:.code,ERW")
#pragma comment(linker,"/SECTION:.codedata,ERW")
#pragma comment(linker, "/MERGE:.codedata=.code")

#pragma code_seg(".code")
#pragma data_seg(".codedata")
#pragma const_seg(".codedata")
