    Subjectwierd current->uid
    hi
    i am doing a project on
    a very simple system call interception module.
    the module is supposed to return the uid of the
    user who made the call to the syscall. i m trying to
    do it thus:

    //in the kernel module
    asmlinkage long my_syscall(arg1,arg2)
    {
    sprintf(buffer, "%s%s%i", arg1,arg2,current->uid);
    //this buffer is later read.
    return original_syscall(arg1,arg2);
    }

    the problem is that the uid returned is always -1.
    i found you had a similar problem very long back
    and had posted a msg on a mailing list.

    could you suggest a way out please.
    thanx
