    SubjectStrange behaviour of devfs wrt /dev/tty

    I noticed the following strange behaviour with devfs (patch-v27,
    kernel 2.1.98). If some program opens /dev/tty (e.g. "cat < /dev/tty")
    /dev/tty suddenly changes owner/group (to the uid/gid of the
    program opening the device) and permissions (600). The problem is:
    all other processes on the system see the _same_ permissions
    of /dev/tty. Shouldn't that be visible only to the processes with
    the same controlling terminal?
    Cheers, Roderich
