FC5 CUPS and Netatalk (fixed?)
I've just fixed an SELinux policy issue on FC5, printing via CUPS to a
printer connected via Netatalk (AppleTalk).
I upgrade installed from FC3 to FC5. I had Netatalk 1.6.x on FC3, with
SELinux enforcing, and could print via CUPS over Ethernet to a printer on a
Mac on Localtalk. After the upgrade (and getting Netatalk working again)
it would only print with SELinux in permissive mode. After a few tries, I
collected the following AVC messages and used audit2allow to make the
module below, installed it, and printing works again.
I don't know if this module is exactly right, or even if it is generally
needed by CUPS or only for PAP with Netatalk.
