Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Dylan Gross 2016-12-22 17:22:28 UTC
Description of problem:

  When an in-place upgrade is performed from RHEL6 to RHEL7, and selinux-policy-targeted RPM is installed, it appears to attempt to re-declare ctdbd_t, possibly first from holdover RHEL6 module, and then from RHEL7 module, which then fails.

Example:
----------------------------------------
Installing : selinux-policy-targeted-3.13.1-102.el7_3.4.noarch                                                                                                                                               1/1
'/etc/selinux/targeted/modules/active/seusers' -> '/etc/selinux/targeted/active/seusers.local'
Re-declaration of type ctdbd_t
Failed to create node
Bad type declaration at /etc/selinux/targeted/tmp/modules/400/ctdbd/cil:2
semodule:  Failed!
------------------------------------


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

  selinux-policy-targeted-3.13.1-102.el7_3.4.noarch     

How reproducible:

Steps to Reproduce:
1.   Start with a RHEL6 server with selinux-policy-targeted installed.
2.   In-place upgrade server to RHEL7


Actual results:

     Error observed during installation of selinux-policy-targeted on RHEL7
----------------------------------------
Installing : selinux-policy-targeted-3.13.1-102.el7_3.4.noarch                                                                                                                                               1/1
'/etc/selinux/targeted/modules/active/seusers' -> '/etc/selinux/targeted/active/seusers.local'
Re-declaration of type ctdbd_t
Failed to create node
Bad type declaration at /etc/selinux/targeted/tmp/modules/400/ctdbd/cil:2
semodule:  Failed!
------------------------------------

Expected results:

    The semodule is able to activate without error

Additional info:

   I'm not entirely sure what the scope of ramifications of the selinux module failing to activate would be.

I don't remember when it happened, but the ctdbd policy module was renamed to ctdb. Both modules define ctdbd_t.
