Summary: This fixes rtentry leak for the cloned interfaces created inside the VNET. PR: 253998 Reported by: rashey at superbox.pl MFC after: 3 days Loopback teardown order is `SI_SUB_INIT_IF`, which happens after `SI_SUB_PROTO_DOMAIN` (route table teardown). Thus, any route table operations are too late to schedule. As the intent of the vnet teardown procedures to minimise the amount of effort by doing global cleanups instead of per-interface ones, address this by adding a relatively light-weight routing table cleanup function, `rib_flush_routes()`. It removes all remaining routes from the routing table and schedules the deletion, which will happen later, when `rtables_destroy()` waits for the current epoch to finish. Test Plan: ``` set_skip:set_skip_group_lo -> passed [0.053s] tail -n 200 /var/log/messages | grep rtentry ``` Reviewers: #network, kp, bz Reviewed By: kp Subscribers: imp, ae Differential Revision: https://reviews.freebsd.org/D29116 |

FreeBSD
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
