Description Brian J. Murrell 2018-02-21 21:09:33 UTC 
Description of problem:
Not sure why this happened.
SELinux is preventing /usr/lib/systemd/systemd-journald from 'map' accesses on the file 2F6D656D66643A73642D73797374656D642D636F726564756D202864656C6574656429.

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

If you believe that systemd-journald should be allowed map access on the 2F6D656D66643A73642D73797374656D642D636F726564756D202864656C6574656429 file 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 'systemd-journal' --raw | audit2allow -M my-systemdjournal
# semodule -X 300 -i my-systemdjournal.pp

Comment 2 Brian J. Murrell 2018-03-08 12:45:53 UTC 
Description of problem:
Not sure why this happened but abrt said it's fixed in selinux-policy-0:3.13.1-283.27.fc27.noarch in updates-testing but I don't see that in updates-testing.  Here: https://mirror.csclub.uwaterloo.ca/fedora/linux/updates/testing/27/x86_64/Packages/s/ for example, no selinux-policy package at all.  Nor here: http://mirror.us.leaseweb.net/fedora/linux/updates/testing/27/x86_64/Packages/s/.

So, while this is a really cool feature, to tell people there is an update availble even in updates-testing, it really only works if it's accurate.
