4672 | * queued for every clearing peer, regardless of whether it is | |
4673 | * relevant to the peer at hand. | |
4674 | * | |
4675 | * Overview: There are 3 different indices which need to be | |
4676 | * scrubbed, potentially, when a peer is removed: | |
4677 | * | |
4678 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
4679 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
4680 | * 3 other routes visible by the peer's adj-out index | |
4681 | * | |
4682 | * 3 there is no hurry in scrubbing, once the struct peer is | |
4683 | * removed from bgp->peer, we could just GC such deleted peer's | |
4684 | * adj-outs at our leisure. | |
4685 | * | |
4686 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
4687 | * invisible via RIB index before peer session is allowed to be | |
4688 | * brought back up. So one needs to know when such a 'search' is | |
4689 | * complete. | |
4690 | * | |
4691 | * Ideally: | |
4692 | * | |
4693 | * - there'd be a single global queue or a single RIB walker | |
4694 | * - rather than tracking which route_nodes still need to be | |
4695 | * examined on a peer basis, we'd track which peers still | |
4696 | * aren't cleared | |
4697 | * | |
4698 | * Given that our per-peer prefix-counts now should be reliable, | |
4699 | * this may actually be achievable. It doesn't seem to be a huge | |
4700 | * problem at this time, | |
4701 | * | |
4702 | * It is possible that we have multiple paths for a prefix from | |
4703 | * a peer | |
