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 of problem:
When I remediate using an Anaconda addon (might be unrelated) with the RHEL-8.4 version of SSG, ospp profile, I see this when I boot into the installed system:
Jun 25 08:19:32 ospp systemd[1]: File /usr/lib/systemd/system/usbguard.service:11 configures an IP firewall (IPAddressDeny=any), but the local system does not support BPF/cgroup based firewalling.
Jun 25 08:19:32 ospp systemd[1]: Proceeding WITHOUT firewalling in effect! (This warning is only shown for the first loaded unit using IP firewalling.)
That's systemd (second message) saying it didn't detect any firewall running and thus it ignored (first message) usbguard's request to have a specific socket firewalled.
Firewalld is however running and has loaded a ruleset, as can be seen from "nft list ruleset":
chain filter_IN_public_allow {
tcp dport 22 ct state { new, untracked } accept
ip6 daddr fe80::/64 udp dport 546 ct state { new, untracked } accept
tcp dport 9090 ct state { new, untracked } accept
}
It would seem that something in the profile is breaking systemd's ability to detect an active firewall.
Version-Release number of selected component (if applicable):
scap-security-guide-0.1.54-5.el8.noarch
Steps to Reproduce:
1. journalctl -b | grep firewall
