5080 | * queued for every clearing peer, regardless of whether it is | |
5081 | * relevant to the peer at hand. | |
5082 | * | |
5083 | * Overview: There are 3 different indices which need to be | |
5084 | * scrubbed, potentially, when a peer is removed: | |
5085 | * | |
5086 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
5087 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
5088 | * 3 other routes visible by the peer's adj-out index | |
5089 | * | |
5090 | * 3 there is no hurry in scrubbing, once the struct peer is | |
5091 | * removed from bgp->peer, we could just GC such deleted peer's | |
5092 | * adj-outs at our leisure. | |
5093 | * | |
5094 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
5095 | * invisible via RIB index before peer session is allowed to be | |
5096 | * brought back up. So one needs to know when such a 'search' is | |
5097 | * complete. | |
5098 | * | |
5099 | * Ideally: | |
5100 | * | |
5101 | * - there'd be a single global queue or a single RIB walker | |
5102 | * - rather than tracking which route_nodes still need to be | |
5103 | * examined on a peer basis, we'd track which peers still | |
5104 | * aren't cleared | |
5105 | * | |
5106 | * Given that our per-peer prefix-counts now should be reliable, | |
5107 | * this may actually be achievable. It doesn't seem to be a huge | |
5108 | * problem at this time, | |
5109 | * | |
5110 | * It is possible that we have multiple paths for a prefix from | |
5111 | * a peer | |
5112 | * if that peer is using AddPath. | |
