Red Hat Bugzilla – Bug 426016
Printing failed because of SELinux denial
Last modified: 2008-06-16 22:56:33 EDT
Description of problem: I have a HP deskjet printer. When I print something from evince, it doesn't work. Version-Release number of selected component (if applicable): evince-0.8.2-1.fc7 How reproducible: every time Steps to Reproduce: 1. Plug in my HP deskjet 2. Try to print from evince Actual results: SELinux violation Additional info: If I run 'setenforce Permissive' as root and try again, it prints. From setroubleshoot browser: Summary SELinux is preventing sh (cupsd_t) "getattr" to /usr/bin/hpijs (hplip_exec_t). Detailed Description SELinux denied access requested by sh. It is not expected that this access is required by sh 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.

I get the same error messages from SELinux. I updated my F7 system on 12/16/07. After the update the HP Deskjet via OpenOffice - Word Processor failed to print. Also, the lp command would not print either. I received the same error messages as those given above from SELinux.
I have the same problem with firefox now. Someone else reported similar trouble with a different brand of printer at bug #251378. In both of our cases, cups reports that the printer is stopped, and if you don't look at the SELinux errors, you'll never figure out why. I'm guessing this is more of a cups problem than an evince problem. Incidentally, restorecon doesn't change the context of hpijs, so it's not simply a matter of that file being accidentally put in the wrong context at some point.
This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '7'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 7's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 7 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists. Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs: http://docs.fedoraproject.org/release-notes/ The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 7 changed to end-of-life (EOL) status on June 13, 2008. Fedora 7 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
