[Pkg-samba-maint] Bug#583508: Bug#583508: smbfs: smbumount does not umount from win2k server

[Leonardo Boselli]

I tried on another host: this is the reply:

leo at student:~$ mkdir loc
leo at student:~$ smbmount \\\\unione\\home loc
**** (normal dialogue, i can read the remote directory)
leo at student:~$ mount
/dev/sda1 on / type ext3 (rw,errors=remount-ro)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
procbususb on /proc/bus/usb type usbfs (rw)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
fusectl on /sys/fs/fuse/connections type fusectl (rw)
/dev/sdb4 on /home type ext3 (rw)
/dev/sdb3 on /tmp type ext2 (rw)
/dev/sda3 on /usr/local type ext3 (rw)
/dev/sda2 on /var type ext3 (rw)
/dev/sdc1 on /var/cache type ext2 (rw)
nfsd on /proc/fs/nfsd type nfsd (rw)
binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc 
(rw,noexec,nosuid,nodev)
/dev/sdb1 on /media/disk type ext3 (rw,nosuid,nodev,uhelper=hal)
//unione/home on /home/leo/loc type cifs (rw,mand,nosuid,nodev,user=leo)
leo at student:~$ umount loc
umount: /home/leo/loc is not in the fstab (and you are not root)
leo at student:~$
leo at student:~$ smbumount \\\\unione\\home
This utility only unmounts cifs filesystems.

exactly the same thing .....and this host has the 32 bit version.
then I su to root and surprise:
student:/home/leo# umount loc
student:/home/leo# ls loc

this time has worked !
It is not enought however, since in unacceptabele tha one user can mount a 
remote share but is unable to umount !!!!

After this test i tried again on the same 64 bit machine :  exactly the 
same result: i can mount as an user, i cannot umount by the same user.
I still consider this an important bug.

I thried again on another "expendable" server and i was never able to 
umount by the same user that mounted, but always i succeeded as root

also: i can mount two times on th seme mount point, an mount command show 
me two times the same mount.
when I rebooted i had two os suc mounts. this could be the reason for the 
lock ?
