4460 | * queued for every clearing peer, regardless of whether it is | |
4461 | * relevant to the peer at hand. | |
4462 | * | |
4463 | * Overview: There are 3 different indices which need to be | |
4464 | * scrubbed, potentially, when a peer is removed: | |
4465 | * | |
4466 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
4467 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
4468 | * 3 other routes visible by the peer's adj-out index | |
4469 | * | |
4470 | * 3 there is no hurry in scrubbing, once the struct peer is | |
4471 | * removed from bgp->peer, we could just GC such deleted peer's | |
4472 | * adj-outs at our leisure. | |
4473 | * | |
4474 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
4475 | * invisible via RIB index before peer session is allowed to be | |
4476 | * brought back up. So one needs to know when such a 'search' is | |
4477 | * complete. | |
4478 | * | |
4479 | * Ideally: | |
4480 | * | |
4481 | * - there'd be a single global queue or a single RIB walker | |
4482 | * - rather than tracking which route_nodes still need to be | |
4483 | * examined on a peer basis, we'd track which peers still | |
4484 | * aren't cleared | |
4485 | * | |
4486 | * Given that our per-peer prefix-counts now should be reliable, | |
4487 | * this may actually be achievable. It doesn't seem to be a huge | |
4488 | * problem at this time, | |
4489 | * | |
4490 | * It is possible that we have multiple paths for a prefix from | |
4491 | * a peer | |
4492 | * if that peer is using AddPath. | |
