Hi all!
It seems to me that you guys are my last hope, but if i am asking in the
wrong place - sorry.
I wrote my first asm program for FreeBSD:
section .code
global _start
_start:
push dword envp
push dword argvp
push dword fname
mov eax,59 ; execve
int 80h
hlt ; i should never get here
section .data
fname db '/bin/sh',0
envp dd 0
argvp dd 0
;End of program
after compiling and linking i run it and got SIGBUS error
when run under gdb i can see that int 80h returns with eax=2 (ENOENT? does
it mean file not found?)
I have a feeling that i have missed something very important.
Thank you.
