    ** So, now perhaps you/SGI could respond to Greg's complaints about the
    ** patch
    ** (http://mail.wirex.com/pipermail/linux-security-module/2001-September/001
    ** 871.html), specifically the repositioning of some of the capable calls
    ** and the  reordering of the ptrace logic.  I provided my $0.02 on those
    ** issues 
    ** (http://mail.wirex.com/pipermail/linux-security-module/2001-September/001
    ** 872.html), but I don't think you or SGI have said anything.  
    * 
    * We can do this, we'll try to get a ptrace only patch for discussion asap,
    * hopefully Monday.
    * 
    
    I've gone back through your patch, and can't see anything wrong with the
    placement of the hooks or the capable calls. In particular the searches I
    did for ptrace vulnerabilities only seemed to affect 2.2, so I'm not sure
    what Greg's comment was aluding too.
    
    Greg, obviously you're more up on kernel development than I am, can you
    give me a hint. Or was it just a general warning "there have been issues
    with this code in the past, be very careful about changing any logic".
    
    Thanks,
    
    richard.
