SubjectStrange behaviour of devfs wrt /dev/tty




Hi,
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
