Acknowledgments: Name: Evgenii Shatokhin (Virtuozzo Team) This was fixed for Fedora with the 4.16 rebases. Note: DCCP modules were blacklisted by default from auto-loading since RHEL-7.5 out of stability and security concerns. This means they won't be automatically loaded when requested by the socket layer - hence the need to load them manually. Nevertheless, as the DCCP modules themselves are present and could be loaded, future Linux kernel updates for RHEL-6 and RHEL-7 may address this issue. This issue has been addressed in the following products: Red Hat Enterprise Linux 6 Via RHSA-2018:1854 https://access.redhat.com/errata/RHSA-2018:1854 This issue has been addressed in the following products: Red Hat Enterprise Linux 7 Via RHSA-2018:3083 https://access.redhat.com/errata/RHSA-2018:3083 This issue has been addressed in the following products: Red Hat Enterprise Linux 7 Via RHSA-2018:3096 https://access.redhat.com/errata/RHSA-2018:3096 |
