+++ This bug was initially created as a clone of Bug #1250842 +++

Description of problem:

Running firewall.cmd to change the permanent config fails like this with setenforce 1:

# firewall-cmd --add-port 1234/tcp --permanent
Error: Backup of '/etc/firewalld/zones/public.xml' failed: [Errno 13] Permission denied: '/etc/firewalld/zones/public.xml.old'

It succeeds with setenforce 0.

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

firewalld-0.3.14.2-4.fc23.noarch

Ahh, selinux version:

selinux-policy-targeted-3.13.1-138.fc23.noarch

Just updated to F23, same issue:

[root@torrent ~]# firewall-cmd --runtime-to-permanent
Error: RT_TO_PERM_FAILED: zone 'public' : org.fedoraproject.FirewallD1.Exception: Backup of '/etc/firewalld/zones/public.xml' failed: [Errno 13] Permission denied: '/etc/firewalld/zones/public.xml.old'
[root@torrent ~]# rpm -q firewalld

[root@torrent ~]# rpm -q selinux-policy-targeted
selinux-policy-targeted-3.13.1-152.fc23.noarch
[root@torrent ~]# setenforce 0
[root@torrent ~]# firewall-cmd --runtime-to-permanent
success

	Was caused by:

#Constraint rule:

#	Possible cause is the source user (system_u) and target user (unconfined_u) are different.

Good news - Firewall-cmd --permanent has started working for me even with setenforce 1 in recent FC23 updates...

I'm not setting this to CLOSED RESOLVED because I'm not the original bug filer and can't verify the issue on the machine it was originally reported on.

Please add the output of "restorecon -rv /etc/firewalld"

I also managed to run into this now. The backup files are not correctly labeled.

This happens if the root user was running firewalld directly or if the user root copied a file into the firewalld configuration directory.

firewalld will create a backup of the old file by renaming it to <filename>.old

Here are steps to reproduce:
1) cp /usr/lib/firewalld/zones/public.xml /etc/firewalld/zones/foobar.xml
2) After 5 seconds when firewalld picked it up, do a change with firewalld: 
   firewall-cmd --permanent --zone=foobar --add-service=samba

Error: Backup of '/etc/firewalld/zones/foobar.xml' failed: [Errno 13] Permission denied: '/etc/firewalld/zones/foobar.xml.old'

# ls -Z /etc/firewalld/zones/foobar.xml*
unconfined_u:object_r:firewalld_etc_rw_t:s0 /etc/firewalld/zones/foobar.xml
    system_u:object_r:firewalld_etc_rw_t:s0 /etc/firewalld/zones/foobar.xml.old
