4785 | * queued for every clearing peer, regardless of whether it is | |
4786 | * relevant to the peer at hand. | |
4787 | * | |
4788 | * Overview: There are 3 different indices which need to be | |
4789 | * scrubbed, potentially, when a peer is removed: | |
4790 | * | |
4791 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
4792 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
4793 | * 3 other routes visible by the peer's adj-out index | |
4794 | * | |
4795 | * 3 there is no hurry in scrubbing, once the struct peer is | |
4796 | * removed from bgp->peer, we could just GC such deleted peer's | |
4797 | * adj-outs at our leisure. | |
4798 | * | |
4799 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
4800 | * invisible via RIB index before peer session is allowed to be | |
4801 | * brought back up. So one needs to know when such a 'search' is | |
4802 | * complete. | |
4803 | * | |
4804 | * Ideally: | |
4805 | * | |
4806 | * - there'd be a single global queue or a single RIB walker | |
4807 | * - rather than tracking which route_nodes still need to be | |
4808 | * examined on a peer basis, we'd track which peers still | |
4809 | * aren't cleared | |
4810 | * | |
4811 | * Given that our per-peer prefix-counts now should be reliable, | |
4812 | * this may actually be achievable. It doesn't seem to be a huge | |
4813 | * problem at this time, | |
4814 | * | |
4815 | * It is possible that we have multiple paths for a prefix from | |
4816 | * a peer | |
4817 | * if that peer is using AddPath. | |
