4647 | * queued for every clearing peer, regardless of whether it is | |
4648 | * relevant to the peer at hand. | |
4649 | * | |
4650 | * Overview: There are 3 different indices which need to be | |
4651 | * scrubbed, potentially, when a peer is removed: | |
4652 | * | |
4653 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
4654 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
4655 | * 3 other routes visible by the peer's adj-out index | |
4656 | * | |
4657 | * 3 there is no hurry in scrubbing, once the struct peer is | |
4658 | * removed from bgp->peer, we could just GC such deleted peer's | |
4659 | * adj-outs at our leisure. | |
4660 | * | |
4661 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
4662 | * invisible via RIB index before peer session is allowed to be | |
4663 | * brought back up. So one needs to know when such a 'search' is | |
4664 | * complete. | |
4665 | * | |
4666 | * Ideally: | |
4667 | * | |
4668 | * - there'd be a single global queue or a single RIB walker | |
4669 | * - rather than tracking which route_nodes still need to be | |
4670 | * examined on a peer basis, we'd track which peers still | |
4671 | * aren't cleared | |
4672 | * | |
4673 | * Given that our per-peer prefix-counts now should be reliable, | |
4674 | * this may actually be achievable. It doesn't seem to be a huge | |
4675 | * problem at this time, | |
4676 | * | |
4677 | * It is possible that we have multiple paths for a prefix from | |
4678 | * a peer | |
