Bugzilla Bug 116731

When I try tro unmount Ipod nano volume in Nautilus, I get the following error:
/usr/bin/eject: unable to eject, last error: Invalid argument. I am using dbus,
hal, and ivman and have added myself to the disk group. I can fix the problem
by making /usr/bin/eject a suid binary.

While doing testing for another bug [1], I noticed that I cannot unmount Ipod
nano device when logged in as myself if I plug in the device when X is in the
GDM login screen. So the SUID bit doesn't completely fix the problem.

(Please note the I upgraded my kernel and portage so I have included emerge
info here again.)

I haven't tested this patch [1] yet but it should fix the error. Relevant
discussion is here [2]. I'll report once I have the chance to test it.

This patch fixes the permission problem so I don't have the SUID
/usr/bin/eject. Please consider applying.

Is this bug still reproducible?

> Is this bug still reproducible?

Yes it is. I have a slightly different configuration now. No ivman, just
gnome-volume-manager. I have downgraded everything to Gentoo stable now (I used
to be ~x86). I still need to chmod u+s /usr/bin/eject for ipod unmount to work
properly.

After getting my iPod and doing some research, this issue is now in two
distinct parts.

1) eject-2.1.4 is required
2) a patch to block/scsi_ioctl.c in linux kernel is required

With patch applied, eject works with my iPod Nano without having to be suid
root.

As such, it's not GNOME bug at all. Re-assigning to kernel team as eject has
already been fixed in portage.

Created an attachment (id=85271) [edit]
Patch scsi block for 2.6.16

Patch ripped from a Ubuntu kernel.

Fixes above issue, request inclusion in gentoo-sources.

Please get that included upstream, and/or fix eject. Ejecting works as a user
over SCSI transport, as long as the device is opened for read+write.

eject-2.1.4 is already fixed.

Note the comment at the bottom - I'll quote here.

What is the proper action for getting this included upstream if you won't put
it in gentoo-sources?

That's an eject bug because it opens for read-only.

From "strace eject -s /dev/sdb1":
open("/dev/sdb1", O_RDONLY|O_NONBLOCK)  = 3

I am using eject v2.1.4

You're right, sorry.

I'll take this then and patch eject as it looks like the kernel is now fine.

Fixed in eject-2.1.4-r1
