webserver

Written as a tiny project to learn more about 64-bit x86 assembly and
the Linux kernel ABI. The syntax here is Intel for GNU AS. The code is
public domain.

Build process

    as -g server.s -o server.o && ld server.o -o exe
    sudo ./exe 

Testing

    nc localhost 80
    GET /anything HTTP/1.0
    POST /anything HTTP/1.0

Warning

The executable needs root permissions because it is listening for
incoming connections everywhere (0.0.0.0). Therefore, if your server is
running on the default address, anyone on the network can access and/or
create any file on your machine.

Change the sockaddr_in struct in the data section to override this.
