Raw Blame History

---id: RHEL-07-040860 status: implemented tag: kernel ---

The tasks in this role set net.ipv6.conf.all.accept_source_route to 0 by default. This prevents the system from forwarding source-routed IPv6 packets.

Deployers can opt out of this change by setting the following Ansible variable:

security_disallow_source_routed_packet_forward_ipv6: no

Refer to "IPv6 source routing: history repeats itself" for more details on IPv6 source routed packets.
