Technical question

[Jimmy Dubuisson]

Hi everybody,

I made a LKM running on a rehat 7.3 because I need to intercept a chdir
system call. The problem is that inside my chdir intercepting function I
would like to use the 'do_execve' function. For this, as you know, I
need to intialize the 'pt_regs' structure with the saved registry values
on the stack. But as you also know, the chdir system call only takes a
string as its argument. So my question is the following :

How can I get these registry values (in fact edx for the list of
environment variables) by using if possible the C language and the
functions available in the kernel ?

Thanks in advance for your response,

Cheers,

Jimmy.
