3935 | * queued for every clearing peer, regardless of whether it is | |
3936 | * relevant to the peer at hand. | |
3937 | * | |
3938 | * Overview: There are 3 different indices which need to be | |
3939 | * scrubbed, potentially, when a peer is removed: | |
3940 | * | |
3941 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
3942 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
3943 | * 3 other routes visible by the peer's adj-out index | |
3944 | * | |
3945 | * 3 there is no hurry in scrubbing, once the struct peer is | |
3946 | * removed from bgp->peer, we could just GC such deleted peer's | |
3947 | * adj-outs at our leisure. | |
3948 | * | |
3949 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
3950 | * invisible via RIB index before peer session is allowed to be | |
3951 | * brought back up. So one needs to know when such a 'search' is | |
3952 | * complete. | |
3953 | * | |
3954 | * Ideally: | |
3955 | * | |
3956 | * - there'd be a single global queue or a single RIB walker | |
3957 | * - rather than tracking which route_nodes still need to be | |
3958 | * examined on a peer basis, we'd track which peers still | |
3959 | * aren't cleared | |
3960 | * | |
3961 | * Given that our per-peer prefix-counts now should be reliable, | |
3962 | * this may actually be achievable. It doesn't seem to be a huge | |
3963 | * problem at this time, | |
3964 | * | |
3965 | * It is possible that we have multiple paths for a prefix from | |
3966 | * a peer | |
3967 | * if that peer is using AddPath. | |
