The posting you are referring to is a 2.4.10 kernel.  I don't even remember
how
many bugs have been fixed since then... so I wouldn't consider this as a
current
bug report.

Regarding your problem, I really don't see how this could happen.  The
network
drivers could be handing some broken skb's up to the stack, and ip_nat_ftp
is
running over the end of the payload in the skb while searching for PORT/PASV
commands.

If you can reproduce the same problem with the 'string' match (but no
ip_nat_ftp) loaded, this would confirm my theory.

Without the respective hardware, I am unable to reproduce that problem.  As
stated before, my prism2/hostap combination was never showing such a problem.
