This a problem with selinux file labels. The losetup command is able to use
files with fsadm_tmp_t or swapfile_t labels only. It means you have to change it.

# dd if=/dev/zero of=/root/testfile bs=1024 count=65536
# ls -Z /root/testfile
-rw-r--r--  root     root     root:object_r:user_home_t        /root/testfile

# chcon -t fsadm_tmp_t /root/testfile
# ls -Z /root/testfile
-rw-r--r--  root     root     root:object_r:fsadm_tmp_t        /root/testfile

# losetup /dev/loop0 /root/testfile
# losetup -a
/dev/loop0: [fd00]:17350081 (/root/testfile)

Danie, can you check if "fsadm_tmp_t" is a good way or there should be any extra
type or permission for any other type (like user_home_t)? Thanks.

Sorry: s/Danie/Dan/ :-)

Comment 3 Daniel Walsh 2006-03-09 18:36:06 UTC

This should be fixes with updated policy in latest rawhide.  We no longer
transition unconfined_t to mount or fsadm.
