Description Joachim Backes 2012-02-23 11:14:47 UTC
Description of problem:

The standard SELINUX is set to SELINUX=enforcing in F17.
Running cups-lpd in F17. I edited /etc/cups/cups-pdf.conf by setting
"Out ${DESKTOP}/PDF". But that did not work: No printing output to the pdf printer landed in ~/Desktop/PDF. 

But after setting SELINUX=permissive (in /etc/selinux/config), all pdf printing appears in ~/Desktop/PDF is desired.

The access right of ~/Desktop/PDF are: drwxrwxr-x

Version-Release number of selected component (if applicable):
cups-pdf-2.6.1-1.fc17.x86_64

How reproducible:
always

Steps to Reproduce:
1. Print some stuff to the PDF printer
2.
3.
  
Actual results:
Nothing appears in the directory given by Out ${DESKTOP}/PDF (in etc/cups/cups-pdf.conf)

Expected results:

Sorry, typo: I meant "Running cups-pdf in F17" (and not "Running cups-lpd in F17")

Please check the audit.log to get the full avc denied message.

And :
ls -Zld $HOME/Desktop
ls -Zld $HOME/Desktop/PDF

Comment 4 Remi Collet 2012-02-24 06:20:13 UTC
So, type for PDF directory is not ok.

Please change it to user_home_t (with chcon or restorecon)
