    Hi,

I am trying to port LIDS to LSM right now, I meet a problem when I deal
with hook in the do_execve(), there is alloc_security() that I can
use. But since I want to check the envp, the bprm here can not give me
this envp,

int do_execve(char * filename, char ** argv, char ** envp, struct pt_regs
* regs)
{
       ..... 
       retval = security_ops->bprm_ops->alloc_security(&bprm);
        if (retval)
 ....
}

I wonder if you can put this hook a little later that the copy_string can
copy envp to bprm or simply add a pointer parameter to alloc_security()?

Thanks,
Huagang
