RHBA-2017:0084 - Bug Fix Advisory

Topic

Updated selinux-policy packages that fix several bugs are now available for Red Hat Enterprise Linux 7.

Description

The selinux-policy packages contain the rules that govern how confined processes run on the system.

This update fixes the following bugs:

• In Red Hat Enterprise Linux 7.3, SELinux denied communication between the Puppet configuration tool and the D-Bus interface when using the timedatectl command. The selinux-policy packages have been updated, and Puppet can now run timedatectl. (BZ#1400505)
• Prior to this update, SELinux policy was rebuilt during online update. Consequently, updating the selinux-policy-targeted package using Yum failed with a traceback. The selinux-policy migration script has been fixed, and the selinux-policy update now works properly. (BZ#1401518)
• Previously, a rule for the Clustered Trivial Database (CTDB) was missing. As a consequence, SELinux denied successful finish of a CTDB failover. The transition rule for the "ctbd_t" domain was added, and a CTDB failover now succeeds. (BZ#1403266)
• Due to a missing SELinux rule, when two nodes of a Red Hat Gluster Storage (RHGS) server were restarted, the Pacemaker tool stopped services on all nodes. The rule for the "glusterd_t" domain has been added, and SELinux denials no longer occur during an RHGS server restart. (BZ#1408125)
• Due to missing policy rules, SELinux denied running systemd in a container. The rules to allow containers to write to "unix_sysctls" and to use file descriptors leaked to them from parent processes were added, and the SELinux denials no longer occur. (BZ#1408126)
• A missing SELinux rule was previously causing errors when adding a webhook using the gluster-eventsapi command. The rule to allow "glusterd_t" domain binds on glusterd UDP port has been added, and adding a webhook using gluster-eventsapi now works properly. (BZ#1408128)

Users of selinux-policy are advised to upgrade to these updated packages, which fix these bugs.
