Version-Release number of selected component (if applicable):
HP Linux Imaging and Printing System (ver. 3.12.9)
PC Sendfax Utility ver. 9.0


How reproducible: always
 


Steps to Reproduce:
1. hp-sendfax -n -f 18884732963 -l debug test
2. observe meaages in 'audit' log file 
3.
  
Actual results: fax works only in SElinux 'PSElinux 'Permissive' mode.


Expected results: fax should work in SElinux 'Enforcing' mode too. 


Additional info: The hplip 3.12.9 version suffers from other 'problems' too. I reported them upstream in 
https://bugs.launchpad.net/hplip/+bug/1055510

Thanks

I think the following line from hplip-3.12.9 release notes [1] could be related:

- Changes done for PrivateTmp feature. Logs get stored in /var/log/hp/tmp

Any idea what to look for Mirek, Dan ?
