3239 | * queued for every clearing peer, regardless of whether it is | |
3240 | * relevant to the peer at hand. | |
3241 | * | |
3242 | * Overview: There are 3 different indices which need to be | |
3243 | * scrubbed, potentially, when a peer is removed: | |
3244 | * | |
3245 | * 1 peer's routes visible via the RIB (ie accepted routes) | |
3246 | * 2 peer's routes visible by the (optional) peer's adj-in index | |
3247 | * 3 other routes visible by the peer's adj-out index | |
3248 | * | |
3249 | * 3 there is no hurry in scrubbing, once the struct peer is | |
3250 | * removed from bgp->peer, we could just GC such deleted peer's | |
3251 | * adj-outs at our leisure. | |
3252 | * | |
3253 | * 1 and 2 must be 'scrubbed' in some way, at least made | |
3254 | * invisible via RIB index before peer session is allowed to be | |
3255 | * brought back up. So one needs to know when such a 'search' is | |
3256 | * complete. | |
3257 | * | |
3258 | * Ideally: | |
3259 | * | |
3260 | * - there'd be a single global queue or a single RIB walker | |
3261 | * - rather than tracking which route_nodes still need to be | |
3262 | * examined on a peer basis, we'd track which peers still | |
3263 | * aren't cleared | |
3264 | * | |
3265 | * Given that our per-peer prefix-counts now should be reliable, | |
3266 | * this may actually be achievable. It doesn't seem to be a huge | |
3267 | * problem at this time, | |
