Description Jarle Bjørgeengen 2015-09-14 08:10:59 EDT
Description of problem:
The package docker-selinux contains necessary additionale rules for docker to work properly when running selinux in targeted mode. The docker-selinux does policy installation by loading a binary module from /usr/share/selinux/packages/ directly with semodule and load_policy. (By using rpm %{POSTIN} routine). This will make a new updated docker.pp in 


However, this file is owned by:

    [root@yme test-nginx]# rpm -qf /etc/selinux/targeted/modules/active/modules/docker.pp 
    [root@yme test-nginx]#
    Version-Release number of selected component (if applicable):

How reproducible:


Steps to Reproduce:
1. Upgrade selinux-policy-targeted
2. Run systemctl restart docker 

Actual results:
restart of docker hangs, because now this is not allowed anymore:

allow docker_t firewalld_t:dbus send_msg;

Expected results:

systemctl restart docker returns with success. 

Additional info:


 yum -y reinstall docker-selinux

# find /usr/share/selinux/devel/ -name docker.if
# rpm -qf /usr/share/selinux/devel/include/contrib/docker.if
# rpm -qf /usr/share/selinux/devel/include/services/docker.if 

The existence of 2 docker.if files causes following problems when compiling a local policy module:

Comment 3 Lukas Vrabec 2015-09-16 10:49:08 EDT
This looks that docker team ship docker selinux module and also selinux team ship docker module. 

Dan, Lokesh, 
Whats are the steps to fix this, Could you ship docker policy from rhel7.3?
Comment 4 Daniel Walsh 2015-09-16 13:04:42 EDT
selinux-policy package should no longer be shipping docker.pp.  It should only be shipped in docker-selinux package.
