    tmpfs

SYSTEMS AFFECTED

    SunOS 4.1.4

PROBLEM

    Yamamori Takenori posted  about yet another  tmpfs problem.   This
    bug is "assertion failed: tp->tn_dir == NULL".   Exploit:

        $ cd /tmp
        $ mkdir a
        $ cd a
        $ vi b (write something to it, but keep the file open)
        [ switch screen ]
        $ rm -r /tmp/a
        [ switch screen ]
        (save the file using :w in vi)

    and then kernel panics.

SOLUTION

    That was fixed by the patch 103314-01.
