3869 | * queued for every clearing peer, regardless of whether it is | |
3870 | * relevant to the peer at hand. | |
3871 | * | |
3872 | * Overview: There are 3 different indices which need to be | |
3873 | * scrubbed, potentially, when a peer is removed: | |
3874 | * | |
3875 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
3876 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
3877 | * 3 other routes visible by the peer's adj-out index | |
3878 | * | |
3879 | * 3 there is no hurry in scrubbing, once the struct peer is | |
3880 | * removed from bgp->peer, we could just GC such deleted peer's | |
3881 | * adj-outs at our leisure. | |
3882 | * | |
3883 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
3884 | * invisible via RIB index before peer session is allowed to be | |
3885 | * brought back up. So one needs to know when such a 'search' is | |
3886 | * complete. | |
3887 | * | |
3888 | * Ideally: | |
3889 | * | |
3890 | * - there'd be a single global queue or a single RIB walker | |
3891 | * - rather than tracking which route_nodes still need to be | |
3892 | * examined on a peer basis, we'd track which peers still | |
3893 | * aren't cleared | |
3894 | * | |
3895 | * Given that our per-peer prefix-counts now should be reliable, | |
3896 | * this may actually be achievable. It doesn't seem to be a huge | |
3897 | * problem at this time, | |
3898 | * | |
3899 | * It is possible that we have multiple paths for a prefix from | |
3900 | * a peer | |
3901 | * if that peer is using AddPath. | |
