Description Michal Ambroz 2017-11-13 14:17:10 UTC 
===== Description of problem:
After upgrade from Fedora 26 to Fedora 27 (Beta at the moment)  The firewalld service stopped to working due to selinux permissions. 
I did try to runt the restorecon on all the  firewalld files , but it didn't helped.

===== How reproducible:
100%

===== Steps to Reproduce:

# service firewalld stop
Redirecting to /bin/systemctl stop firewalld.service
# service firewalld start
Redirecting to /bin/systemctl start firewalld.service
Job for firewalld.service failed because a fatal signal was delivered to the control process.
See "systemctl  status firewalld.service" and "journalctl  -xe" for details.

Comment 1 Michal Ambroz 2017-11-13 14:44:29 UTC 
Trying firewalld to perform this 'map' access using audit2allow made the firewalld to start:

journalctl  -xe|grep AVC|grep firewall | audit2allow -M firewallmap

semodule -i firewallmap.pp

But it brought some additional selinux errors - mostly access to some temporary files in /dev/mqueue/XXXXXXXXX /var/tmp/XXXXXXXXX /dev/shm/XXXXXXXXX /tmp/XXXXXXXXX:

journalctl -xe|grep firewalld | cut -d ':' -f 4- |sort -u

Having the selinux-policy-3.13.1-283.16.fc27, but firewalld doesn't start after reboot.

# rpm -q selinux-policy
selinux-policy-3.13.1-283.16.fc27.noarch

# rpm -q firewalld
firewalld-0.4.4.5-3.fc27.noarch

Seems to be still related to denied map on vda1 device.

After adding that "allow firewalld_t bin_t:file map;" - the firewalld starts, but still is complaining about lots of stuff on root device.
Log attached.

Comment 7 Ben Cotton 2018-11-27 14:34:12 UTC 
This message is a reminder that Fedora 27 is nearing its end of life.
On 2018-Nov-30  Fedora will stop maintaining and issuing updates for
Fedora 27. It is Fedora's policy to close all bug reports from releases
that are no longer maintained. At that time this bug will be closed as
EOL if it remains open with a Fedora  'version' of '27'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 27 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
Comment 8 Ben Cotton 2018-11-30 22:38:26 UTC 
Fedora 27 changed to end-of-life (EOL) status on 2018-11-30. Fedora 27 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
