Brother DCP-130C SELinux blocking
Last modified: 2008-10-20 10:55:56 EDT
Description of problem: Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: Summary SELinux is preventing /usr/bin/brprintconf_dcp130c (cupsd_t) "write" to inf (usr_t). Detailed Description SELinux denied access requested by /usr/bin/brprintconf_dcp130c. It is not expected that this access is required by /usr/bin/brprintconf_dcp130c 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 inf, restorecon -v inf 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.

Fixed in selinux-policy-2.6.4-25.fc7 chcon -R -t cupsd_rw_etc_t /usr/local/Brother/inf Should allow this to work
Closing as fixes are in the current release

Seems like this needs fixing again in Fedora 9.
Why the SELinux context on the system is correct, the problem is the rpm does not specify the directory so it must be created in the post install and not labeled correctly. So there is nothing I can do to fix this. Brother either needs to include /usr/local/Brother/*/inf In the rpm payload or run restorecon in the post install script.
