Description M. Scherer 2018-06-22 12:12:07 UTC
Description of problem:

conntrackd fail with the following message:
juin 22 11:56:01 mune.rht.gluster.org conntrackd[13481]: ERROR: conntrackd cannot start, please check the logfile for more info

in turn the error in the log is

[Fri Jun 22 11:56:01 2018] (pid=13481) [ERROR] can't open channel socket
[Fri Jun 22 11:56:01 2018] (pid=13481) [ERROR] initialization failed

Looking in audit.log, this is the AVC (after using semodule -DB to show the message) :

type=AVC msg=audit(1529668337.138:407604): avc:  denied  { net_admin } for  pid=13445 comm="conntrackd" capability=12  scontext=system_u:system_r:conntrackd_t:s0 tcontext=system_u:system_r:conntrackd_t:s0 tclass=capability permissive=1

# grep 1529668337.138 /var/log/audit/audit.log |audit2allow  -

#============= conntrackd_t ==============
allow conntrackd_t self:capability net_admin;

Adding that capability make it work.
here is a patch for that on https://github.com/fedora-selinux/selinux-policy-contrib/pull/61 but ideally, it should be backported on F28 too.

Version-Release number of selected component (if applicable):

How reproducible:
each time

Steps to Reproduce:
1. install conntrackd and configure it using unicast
2. restart it

Actual results:
the service seems to start fine, but later fail

Expected results:
the service start and survive
