Description of problem: Summary SELinux is preventing /usr/bin/hpijs (cupsd_t) "execute_no_trans" to /usr/bin/hpijs (hplip_exec_t). Detailed Description SELinux denied access requested by /usr/bin/hpijs. It is not expected that this access is required by /usr/bin/hpijs and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access. Allowing Access Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for /usr/bin/hpijs, restorecon -v /usr/bin/hpijs If this does not work, there is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package.

Created attachment 284751 [details] 4 SELinux failures (when permissive) printing an image After I set up an HP OfficeJet 5610, I saw these 4 SELinux failures (when in permissive mode) when trying to print an image using hp-print or hp-toolbox. In enforcing mode, the first one caused printing to fail (but the job stayed in the queue). Oddly enough, I didn't have this problem when I was using a PSC 1610, doing pretty much the same things.
What does 'rpm -q selinux-policy-targeted' say?
Oh, never mind, it's selinux-policy-2.6.4-61.fc7.
dwalsh: I've tried selinux-policy-2.6.4-62.fc7 from koji and it nearly works. The only problem is that /var/spool/cups is getting context var_spool_t which is incorrect. This line seems to have been removed from cups.fc: /var/spool/cups(/.*)? gen_context(system_u:object_r:print_spool_t,mls_systemhigh) After doing this: chcon -R system_u:object_r:print_spool_t /var/spool/cups then printing to an HP PSC 2210 works fine without any audit messages with selinux-policy-2.6.4-62.fc7, so we just need to get the file context right on the spool directory.
Created attachment 287421 [details] policy-cups-spool.patch Here's an incremental patch to do that.
