Description Brian Wheeler 2005-06-17 14:57:51 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4

Description of problem:
While trying to debug a disk image using fdisk I found that selinux will not allow me to run fdisk on the file.  sfdisk doesn't work either.  I've done it in earlier versions, so I know its something that's possible.  

Here are the relevant lines from audit.log:
type=PATH msg=audit(1119034442.581:16583602): item=0 name="bootfile.dump" inode=737318 dev=fd:00 mode=040775 ouid=11907 ogid=500 rdev=00:00

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. dd if=/dev/zero of=disk.image bs=1048576 count=5
2. /sbin/fdisk disk.image

Actual Results:  "Unable to open disk.image" & fdisk exits.

Expected Results:  Image should have opened and fdisk allowed me to make modifications.

What policy are you running.  This should be allowed.

Comment 2 Brian Wheeler 2005-06-20 09:16:19 EDT
I'm running targeted.  Its the standard FC4 setup (via an upgrade of FC3) so
there shouldn't be any surprises...

Comment 3 Daniel Walsh 2005-06-20 14:46:20 EDT
selinux-policy-targeted-1.23.18-12 should fix this.
Comment 4 Brian Wheeler 2005-06-20 14:50:47 EDT
Yes, that fixes it.  Thanks!
