3137 | * queued for every clearing peer, regardless of whether it is | |
3138 | * relevant to the peer at hand. | |
3139 | * | |
3140 | * Overview: There are 3 different indices which need to be | |
3141 | * scrubbed, potentially, when a peer is removed: | |
3142 | * | |
3143 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
3144 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
3145 | * 3 other routes visible by the peer's adj-out index | |
3146 | * | |
3147 | * 3 there is no hurry in scrubbing, once the struct peer is | |
3148 | * removed from bgp->peer, we could just GC such deleted peer's | |
3149 | * adj-outs at our leisure. | |
3150 | * | |
3151 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
3152 | * invisible via RIB index before peer session is allowed to be | |
3153 | * brought back up. So one needs to know when such a 'search' is | |
3154 | * complete. | |
3155 | * | |
3156 | * Ideally: | |
3157 | * | |
3158 | * - there'd be a single global queue or a single RIB walker | |
3159 | * - rather than tracking which route_nodes still need to be | |
3160 | * examined on a peer basis, we'd track which peers still | |
3161 | * aren't cleared | |
3162 | * | |
3163 | * Given that our per-peer prefix-counts now should be reliable, | |
3164 | * this may actually be achievable. It doesn't seem to be a huge | |
3165 | * problem at this time, | |
43143c8f DS |
3166 | * |
