2735 | * queued for every clearing peer, regardless of whether it is | |
2736 | * relevant to the peer at hand. | |
2737 | * | |
2738 | * Overview: There are 3 different indices which need to be | |
2739 | * scrubbed, potentially, when a peer is removed: | |
2740 | * | |
2741 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
2742 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
2743 | * 3 other routes visible by the peer's adj-out index | |
2744 | * | |
2745 | * 3 there is no hurry in scrubbing, once the struct peer is | |
2746 | * removed from bgp->peer, we could just GC such deleted peer's | |
2747 | * adj-outs at our leisure. | |
2748 | * | |
2749 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
2750 | * invisible via RIB index before peer session is allowed to be | |
2751 | * brought back up. So one needs to know when such a 'search' is | |
2752 | * complete. | |
2753 | * | |
2754 | * Ideally: | |
2755 | * | |
2756 | * - there'd be a single global queue or a single RIB walker | |
2757 | * - rather than tracking which route_nodes still need to be | |
2758 | * examined on a peer basis, we'd track which peers still | |
2759 | * aren't cleared | |
2760 | * | |
2761 | * Given that our per-peer prefix-counts now should be reliable, | |
2762 | * this may actually be achievable. It doesn't seem to be a huge | |
2763 | * problem at this time, | |
