Details

Description:

When I try to mount an image with a 32-byte offset

mount -o loop,offset=32 test.iso /var/tmp/mount_dir

I got

mount: test.iso: failed to setup loop device: Numerical result out of range

or with losetup:
losetup: test.iso: failed to set up loop device, offset is not 512-byte aligned.

Additional info: util-linux 2.32.2-1

Steps to reproduce:

sudo mount -o loop,offset=32 test.iso mount_dir
or
losetup -o 32 /dev/loop0 test.iso

But util-linux 2.20 seems to work.
This task depends upon

This is bug in extra check that we have in losetup code to detect non-synced loop devices. Fixed by upstream commit a7d5202b5e49b7e33336818e00d240b8badddbb7.
