Bug#435413: oops when Windows server sent bad domain name null terminator

["Rodrigo Campos" <rodrigocc@gmail.com>]

Package: linux-image-2.6.18-5-686
Version: 2.6.18.dfsg.1-13
Severity: normal

We have seen the same problems that where reported here[1] and hit it
mounting, copying and unmounting from windows server several times.
Then we realise we can easily reproduce this looping on:

PASSWD="xxx" mount -t cifs -o username=xxx,iocharset=utf8
//hercules/<share> /mnt/tmp/
umount /mnt/tmp

We have only seen the oops using iocharset=utf8 and cifs

And applying this patch [2] fix it too. So please consider applying it
into the debian kernel, as it's a serious bug (causes an oops) and
easy to trigger on samba (cifs) clients (since debian default encoding
is utf8).

Thanks,
Rodrigo
