Hi guys im using turboprint drivers for my IP 1000 Canon. When i try
to print from Open Office i get this below:
sealert -l 26616fa9-ba9f-44fb-9cf2-d1940f15217f
Summary
SELinux is preventing /lib/ld-2.6.so (cupsd_t) "execmem" to <Nieznane>
(cupsd_t).
Detailed Description
SELinux denied access requested by /lib/ld-2.6.so. It is not
expected that
this access is required by /lib/ld-2.6.so 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
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.

Sorry about missing this, my junk mail filters ate it.
This looks like a badly written application that would require execmem.
You can allow this by executing
# grep execmem /var/log/audit/audit/audit.log | audit2allow -M mycups
# semodule -i mycups.pp
You should report this as a bug to turboprint.
