Description Masahiro Matsuya 2023-04-07 10:25:21 UTC

Description of problem:

RHEL8.7 installation with CDN repository outputs the following error in pop-up dialog window.

Something went wrong during the final hardening: Content evaluation and remediation with the oscap tool failed: OpenSCAP Error: Failed to locate a datastream with ID matching 'scap_org.open-scap_datastream_from_xccdf_ssg-rhel8-xccdf-1.2.xml' ID and checklist inside matching 'scap_org.open-scap_cref_ssg-rhel8-xccdf-1.2.xml' ID. [/builddir/build/BUILD/openscap-1.3.6/src/DS/ds_sds_session.c:223]


This is caused by the datastream id changed in the latest scap-security-guide package.

With scap-security-guide-0.1.63-4.el8.noarch (in 8.7GA):

# grep datastream /usr/share/xml/scap/ssg/content/ssg-rhel8-ds.xml
  <ds:data-stream id="scap_org.open-scap_datastream_from_xccdf_ssg-rhel8-xccdf-1.2.xml" scap-version="1.3" use-case="OTHER">


With scap-security-guide-0.1.66-2.el8_7.noarch.rpm:

# grep datastream /usr/share/xml/scap/ssg/content/ssg-rhel8-ds.xml
  <ds:data-stream id="scap_org.open-scap_datastream_from_xccdf_ssg-rhel8-xccdf.xml" scap-version="1.3" use-case="OTHER">


In shorts, "-1.2" was removed from datastream id in the latest scap-security-guide package. 


The datastream id is taken from /usr/share/xml/scap/ssg/content/ssg-rhel8-ds.xml in the stage2 image, when GUI spoke for security profile finishes.

But, the remediate is executed in the chroot environment after latest package installation. So, the saved datastream id doesn't match with the one in the latest package, and the error is output.

Maybe, it's required to pick up the datastream id again from the latest package just before remediate is executed.


Version-Release number of selected component (if applicable):
Red Hat Enterprise Linux 

How reproducible:
Always

Steps to Reproduce:
1. Start GUI installation of RHEL8.7
2. Select any security profile like stig
3. Register the host into Customer Portal (CDN)
4. Set CDN as the package repository
5. Start the installation

Actual results:

The following error is output, and installation stops. (it can be resumed by pressing button)

Something went wrong during the final hardening: Content evaluation and remediation with the oscap tool failed: OpenSCAP Error: Failed to locate a datastream with ID matching 'scap_org.open-scap_datastream_from_xccdf_ssg-rhel8-xccdf-1.2.xml' ID and checklist inside matching 'scap_org.open-scap_cref_ssg-rhel8-xccdf-1.2.xml' ID.


Expected results:

Any error is not output. The installation completes without stopping in any popup dialog window.

Kudos to Masahiro for the great analysis,
this issue is caused by unexpected interaction between the scap-security-guide content project's build system that determines the datastream ID, recent z-stream content updates across many RHEL releases, and by a way how the addon works in the GUI installation mode.

The issue can't be fixed easily for existing RHELs, as the addon is already on those affected installation images, and changing the datastream ID again would cause problems elsewhere.
I can advise to use workarounds that we will draft, or to wait for the next minor version that won't suffer from this issue.

This problem has been triggered by a change in the scap-security-guide package. The fix will be implemented in the scap-security-guide package, we won't change the oscap-anaconda-addon component when fixing this bug. Therefore, I'm switching the bug to scap-security-guide component.

Comment 11 Jan Černý 2023-07-19 15:00:46 UTC

This bug isn't reproducible in RHEL 8.9, because the `scap-security-guide` RPM package shipped in RHEL 8.9 installation image already contains the data stream ID without the `-1.2.` suffix, so there is no difference between the IDs in the content in the installation image and the content in the repository, so the bug can't happen.

For the resolution on RHEL 8.6 z-stream, please track the 8.6.z clone: https://bugzilla.redhat.com/show_bug.cgi?id=2223967.
