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 Shawn Wells 2016-11-08 02:25:16 UTC 
When installing RHEL 7.3 using SCAP security profile, "CCE-80258-7 - Disable KDump Kernel Crash Analyzer (kdump)" fails to take effect.

Comment 3 redhatrises 2016-11-08 14:34:46 UTC 
Shawn,

Since you were testing this with anaconda, is this because kdump is configured/enabled/disabled on firstboot?
Comment 4 Watson Yuuma Sato 2017-04-11 12:23:54 UTC 
To be able to disable services through anaconda remediation we need add support for 'service' fix element in oscap-anaconda-addon.
Comment 5 Watson Yuuma Sato 2017-04-11 13:02:55 UTC 
There is also another approach using an Anaconda addon (com_redhat_kdump) that can disable kdump, but oscap-anaconda-addon doesn't support this fix element too.
Comment 6 redhatrises 2017-04-11 13:17:26 UTC 
I say that we should add both 'service' and 'com_redhat_kdump' to the oscap-anaconda-addon to better support kickstart builds.

Comment 8 Watson Yuuma Sato 2017-04-11 16:07:59 UTC 
Although there is no anaconda remediation, I did not understand why the post-install evaluation and remediation would not fix it, if there is script remediation for this.

After some investigation I found out that com_redhat_kdump addon runs right after oscap-anaconda-addon and applies its configuration, and default configuration is kdump enabled. See attached log snippet from anaconda.
Comment 9 Watson Yuuma Sato 2018-06-07 08:25:48 UTC 
With latest version of oscap-anaconda-addon (0.9), and following patches to SSG, we can disable kdump at install time.

Hi, it looks like this is still somehow buggy - the anaconda has been properly informed to disable kdump (the spoke has updated to kdump disable by profile selection).
Comment 12 Marek Haicman 2018-09-16 21:27:04 UTC 
My finding in Comment 11 was manifestation of Bug 1629490. Kdump is truly disabled by the profile after reboot of the machine in version scap-security-guide-0.1.40-5.el7.

Verified manually.
