5555 | * queued for every clearing peer, regardless of whether it is | |
5556 | * relevant to the peer at hand. | |
5557 | * | |
5558 | * Overview: There are 3 different indices which need to be | |
5559 | * scrubbed, potentially, when a peer is removed: | |
5560 | * | |
5561 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
5562 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
5563 | * 3 other routes visible by the peer's adj-out index | |
5564 | * | |
5565 | * 3 there is no hurry in scrubbing, once the struct peer is | |
5566 | * removed from bgp->peer, we could just GC such deleted peer's | |
5567 | * adj-outs at our leisure. | |
5568 | * | |
5569 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
5570 | * invisible via RIB index before peer session is allowed to be | |
5571 | * brought back up. So one needs to know when such a 'search' is | |
5572 | * complete. | |
5573 | * | |
5574 | * Ideally: | |
5575 | * | |
5576 | * - there'd be a single global queue or a single RIB walker | |
5577 | * - rather than tracking which route_nodes still need to be | |
5578 | * examined on a peer basis, we'd track which peers still | |
5579 | * aren't cleared | |
5580 | * | |
5581 | * Given that our per-peer prefix-counts now should be reliable, | |
5582 | * this may actually be achievable. It doesn't seem to be a huge | |
5583 | * problem at this time, | |
5584 | * | |
5585 | * It is possible that we have multiple paths for a prefix from | |
5586 | * a peer | |
5587 | * if that peer is using AddPath. | |
