Description of problem:
SELinux is preventing (uetoothd) from 'remount' accesses on the filesystem .

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

If you believe that (uetoothd) should be allowed remount access on the  filesystem 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 '(uetoothd)' --raw | audit2allow -M my-uetoothd
# semodule -X 300 -i my-uetoothd.pp

To fix labels on your system. 

Thanks,

I don't know if this is selinux or uetoothd problem. AVC showed up after boot to F28 upgraded from F27.

Well, then this restore should be part of system upgrade process.

Comment 7 Paul W. Frields 2018-03-14 14:17:23 UTC
I did the upgrade to the prerelease as well, and also did (as root) 'touch /.autorelabel' and restarted to get a full relabel. Problem still happened after graphical login:

Comment 8 Paul W. Frields 2018-03-14 14:33:54 UTC
Apologies, I don't have the latest policy apparently.  I just did:

$ mkdir tmp-sp && cd tmp-sp
$ bodhi updates download --updateid FEDORA-2018-59cbf1effc
$ sudo dnf update ./selinux-policy*.rpm

This should take care of the problem, I hear.

Bug is fixed in newer selinux-policy package version: 
https://koji.fedoraproject.org/koji/buildinfo?buildID=1061018

But if you won't reboot the system please remount /sys/fs/bpf filesystem.
