Re: smbmount and mount [and spaces in devices]

Package: mount
Version: 2.7l-4

	This is a bug. I'm opening a bug report. Credit goes to Jens.

	Actually, it isn't strange. Status of currently mounted
	filesystems is saved in /etc/mtab, and this file has one
	line per mount, fields separated with a _space_. So, if
	you have a mount point/device with a space, fields are split

	It has nothing to do with samba - you can easily reproduce it
	$ touch 'foo bar'
	$ /sbin/mke2fs 'foo bar' 123
	$ sudo mount -o loop 'foo bar' /mnt
	$ mount
	/home/tv/foo on bar type /mnt (ext2)

	Maybe the fields with spaces should be quoted? What programs
	read /etc/mtab?

	/proc/mounts logs that example as /dev/loop1, so it is not vulnerable,
	atleast not with loop devices. Haven't tested others.
	This is with frozen, kernel 2.0.33.
