5485 | * queued for every clearing peer, regardless of whether it is | |
5486 | * relevant to the peer at hand. | |
5487 | * | |
5488 | * Overview: There are 3 different indices which need to be | |
5489 | * scrubbed, potentially, when a peer is removed: | |
5490 | * | |
5491 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
5492 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
5493 | * 3 other routes visible by the peer's adj-out index | |
5494 | * | |
5495 | * 3 there is no hurry in scrubbing, once the struct peer is | |
5496 | * removed from bgp->peer, we could just GC such deleted peer's | |
5497 | * adj-outs at our leisure. | |
5498 | * | |
5499 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
5500 | * invisible via RIB index before peer session is allowed to be | |
5501 | * brought back up. So one needs to know when such a 'search' is | |
5502 | * complete. | |
5503 | * | |
5504 | * Ideally: | |
5505 | * | |
5506 | * - there'd be a single global queue or a single RIB walker | |
5507 | * - rather than tracking which route_nodes still need to be | |
5508 | * examined on a peer basis, we'd track which peers still | |
5509 | * aren't cleared | |
5510 | * | |
5511 | * Given that our per-peer prefix-counts now should be reliable, | |
5512 | * this may actually be achievable. It doesn't seem to be a huge | |
5513 | * problem at this time, | |
5514 | * | |
5515 | * It is possible that we have multiple paths for a prefix from | |
5516 | * a peer | |
5517 | * if that peer is using AddPath. | |
