4565 | * queued for every clearing peer, regardless of whether it is | |
4566 | * relevant to the peer at hand. | |
4567 | * | |
4568 | * Overview: There are 3 different indices which need to be | |
4569 | * scrubbed, potentially, when a peer is removed: | |
4570 | * | |
4571 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
4572 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
4573 | * 3 other routes visible by the peer's adj-out index | |
4574 | * | |
4575 | * 3 there is no hurry in scrubbing, once the struct peer is | |
4576 | * removed from bgp->peer, we could just GC such deleted peer's | |
4577 | * adj-outs at our leisure. | |
4578 | * | |
4579 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
4580 | * invisible via RIB index before peer session is allowed to be | |
4581 | * brought back up. So one needs to know when such a 'search' is | |
4582 | * complete. | |
4583 | * | |
4584 | * Ideally: | |
4585 | * | |
4586 | * - there'd be a single global queue or a single RIB walker | |
4587 | * - rather than tracking which route_nodes still need to be | |
4588 | * examined on a peer basis, we'd track which peers still | |
4589 | * aren't cleared | |
4590 | * | |
4591 | * Given that our per-peer prefix-counts now should be reliable, | |
4592 | * this may actually be achievable. It doesn't seem to be a huge | |
4593 | * problem at this time, | |
4594 | * | |
4595 | * It is possible that we have multiple paths for a prefix from | |
4596 | * a peer | |
