Description Graham Miller 2018-02-06 22:52:13 UTC 
Description of problem:
After upgrading Fedora from 26 to 27. Using cinnamon desktop.

Simply login as a sudo user and this alert appears in the task bar.

cinnamon.x86_64 - 3.6.7-3.fc27 
selinux-policy.noarch - 3.13.1-283.21.fc27
SELinux is preventing addconn from 'search' accesses on the directory /var/lib/unbound.

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

If you believe that addconn should be allowed search access on the unbound directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'addconn' --raw | audit2allow -M my-addconn
# semodule -X 300 -i my-addconn.pp

Comment 1 Graham Miller 2018-02-06 23:12:58 UTC 
Found that the upgrade to Fedora 27 did not upgrade all packages. selinux-policy* where on the list needing further updates.

$sudo dnf update - failed with conflicts between dnf-utils and yum-utils. So I:
$sudo dnf remove yum-utils

$sudo dnf update now succeeded. I will reboot now and see if the selinux policy alert appears.

New selinux package versions:-
selinux-policy-3.13.1-283.24.fc27.noarch
selinux-policy-targeted-3.13.1-283.24.fc27.noarch
Comment 2 Graham Miller 2018-02-06 23:23:04 UTC 
Reboot and login as same user:
- Same result. Same selinux alert.
Comment 3 Graham Miller 2018-02-12 08:36:20 UTC 
Another way of generating the selinux alert is after a cinnamon crash. The subsequent refresh of the gui environment seemed to cause this selinux alert.

BTW, the crash seemed to sprout from right clicking on the NextCloud app running (accessible from the cinnamon task bar)
Probably this one: nextcloud-client-2.3.3-2.fc27.x86_64
Comment 4 Graham Miller 2018-02-15 20:50:15 UTC 
This alert is not triggered by simply logging off and back in again. It requires a reboot to trigger more alerts.

The SETroubleshoot alert list shows it "Occurred" 4 times.
Comment 5 Graham Miller 2018-03-11 07:00:12 UTC 
I have not noticed this alert for a little while now.

selinux-policy.noarch 3.13.1-283.26.fc27                                      selinux-policy-targeted.noarch 3.13.1-283.26.fc27 

The nextcloud-client is still the same version.
The kernel is now: 4.15.6-300.fc27

So maybe it is solved.
