[Bug 524450] [NEW] smbd panic using root postexec

[Chris Weiss]

Public bug reported:

Binary package hint: samba

Using ubuntu 9.04, samba 3.3.2, package version 2:3.3.2-1ubuntu3.3
I have some shares for which I use a "root preexec" and "root postexec" to loop mount and unmount an ISO for so I can share some CDrom instead of carrying them all over the place or extracting them (I also mount them from VMWare so i want to keep them as ISO's) and this setup has been working great on 8.04 with samba 3.0.28a.

on 9.04, the preexec works, but on disconnecting from the share the
postexec doesn't seem to fire (or at least the loop mounted ISO  doesn't
get unmounted) and smbd panics.  Running my postexec script manually
does work.  I've attached the log that shows the panic.

in the log you can me trying 2 shares, both are defined the same way,
but the 2nd has a "force user=root" in an attempt to see if it's an odd
permissions issue.
