RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. 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 Martin Žember 2015-01-14 17:06:31 UTC 
Description of problem:
Validating of OVAL results displays:
var_check has been supplied for the ind-def:var_ref entity so a var_ref should also be provided

Version-Release number of selected component (if applicable):
openscap-1.1.1-2.el7 (this did not happen in openscap-1.0.3-2.el7)

How reproducible:
At least once

Steps to Reproduce:
wget http://usgcb.nist.gov/usgcb/content/scap/USGCB-rhel5desktop-1.0.5.0.zip     # Downloading...they have a lot of outages. Sometimes it works sometimes it doesn't."
unzip USGCB-rhel5desktop-1.0.5.0.zip -d usgcb     # Unzipping"
oscap xccdf eval --profile united_states_government_configuration_baseline --results usgcb-xccdf-results.xml --oval-results usgcb/usgcb-rhel5desktop-xccdf.xml     # Evaluating profile 'usgcb'"
oscap xccdf validate-xml usgcb-xccdf-results.xml     # Validating XCCDF results"
oscap oval validate-xml --results --schematron usgcb-rhel5desktop-oval.xml.result.xml     # Validating OVAL results" 

Actual results:
The last command 'oscap oval validate-xml --results --schematron usgcb-rhel5desktop-oval.xml.result.xml' outputs this:
<?xml version="1.0"?>
oval:gov.nist.usgcb.rhel:obj:256 - a var_check has been supplied for the ind-def:var_ref entity so a var_ref should also be provided
oval:gov.nist.usgcb.rhel:obj:201061 - a var_check has been supplied for the ind-def:var_ref entity so a var_ref should also be provided
oval:gov.nist.usgcb.rhel:obj:200841 - a var_check has been supplied for the ind-def:var_ref entity so a var_ref should also be provided
oval:gov.nist.usgcb.rhel:obj:200831 - a var_check has been supplied for the ind-def:var_ref entity so a var_ref should also be provided
oval:gov.nist.usgcb.rhel:obj:200800 - a var_check has been supplied for the ind-def:var_ref entity so a var_ref should also be provided

Invalid OVAL Results content(5.8) in usgcb-rhel5desktop-oval.xml.result.xml.
(return code 2)

Expected results:
Nothing (return code 0)

Comment 2 Martin Preisler 2015-01-15 13:25:25 UTC 
I have just reproduced this issue with openscap from maint-1.0.

Are you sure this issue is not reproducible with openscap-1.0.3-2.el7? It could be that it was introduced between 1.0.3 and maint-1.0 HEAD.

Have bisected the revision tree and this is the commit that breaks.

$ git bisect good

    Export var_check in OVAL object when var_ref is present
    
    Fixes validation issues with schematron, such as:
    
    oval:mil.disa.fso.redhat.rhel6:obj:3184 - a var_ref has been supplied for the
    ind-def:pattern entity so a var_check should also be provided

That is the fix for bz#1159289.

Seems we used to export var_check too rarely and now we export it too often. Will investigate further.

Note to myself, there was another commit by Martin, that needs to be cherry-picked here.
