Description Ricky Burgin 2011-06-01 12:23:08 UTC
This occured whilst installing driver for a Samsung CLX-3175N network printer.

SELinux is preventing /usr/lib/cups/daemon/cups-driverd from 'read' accesses on the file CLP-310-600x600cms2.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that cups-driverd should be allowed read access on the CLP-310-600x600cms2 file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep cups-driverd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2011-06-01 12:27:53 UTC
Where is CLP-310-600x600cms2 located? 

You will need to fix a label on this file

# restorecon -R -v PATHTO/CLP-310-600x600cms2

I guess you moved this file from your homedir to a location.

If I am wrong, please reopen the bug.

Comment 2 Ricky Burgin 2011-06-01 12:56:18 UTC
Hi Miroslav,

I'm just running an installation script straight from Samsung themselves, so it's likely the script not taking SELinux into account.

[root@office ricky]# updatedb
[root@office ricky]# locate CLP-310-600x600cms2

What do you think?

Comment 3 Daniel Walsh 2011-06-01 14:53:28 UTC
Yes the script is probably mv'ing content into those system directories which maintains the context of the users homedir.  Could you open a bug with samsung, to just run restorecon on the newly created directory.

Something like

[ -x /sbin/restorecon ] && /sbin/restorecon -R /usr/share/cups/model/samsung /opt/Samsung

Comment 4 Miroslav Grepl 2011-06-01 15:32:11 UTC
And you need to run

# restorecon -R -v /opt/Samsung/mfp/share/ppd/cms/CLP-310-600x600cms2 /usr/share/cups/model/samsung/cms/CLP-310-600x600cms2

Comment 5 Ricky Burgin 2011-06-01 15:46:36 UTC
They don't seem to have a point of contact; presumably because the context isn't changed, this isn't a problem with selinux policy then?

Comment 6 Daniel Walsh 2011-06-01 17:23:11 UTC
Well SELinux requires proper labels, since their install tool is putting bad labels on the system, there really is no way for SELinux to handle this.
