Description of problem:
Trying to send a fax with hplip.

SELinux is preventing /usr/bin/python2.7 from 'open' accesses on the file /var/lib/rpm/.dbenv.lock.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that python2.7 should be allowed open access on the .dbenv.lock file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep hpfax /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Miroslav Grepl 2013-08-08 09:11:26 EDT
Did you need to switch to permissive mode?
Comment 2 Kapoios Kanenas 2013-08-16 09:16:37 EDT
No I didn't. Though I added the rule(s) generated by audit2allow but still didn't work.
Comment 3 Daniel Walsh 2013-08-16 13:43:16 EDT
Any idea why hpfax would be reading the rpm database?
Comment 4 Tim Waugh 2013-08-20 10:31:43 EDT
No, none. There is some code to do that (installer/core_install.py can run yum) but I can't see how hpfax could end up there.
Comment 5 Daniel Walsh 2013-08-28 13:26:53 EDT
Well Kapoios is this still happening?  I would not modify your policy with audit2allow.  This should not be needed.
Comment 6 Kapoios Kanenas 2013-09-23 16:46:25 EDT
No. I can't reproduce this issue anymore.
