Merge #19670: Protect localhost and block-relay-only peers from eviction
752e6ad5336d5af0db9fe16d24c0c6aa25b74a3f Protect localhost and block-relay-only peers from eviction (Suhas Daftuar)
Pull request description:
Onion peers are disadvantaged under our eviction criteria, so prevent eventual
eviction of them in the presence of contention for inbound slots by reserving
some slots for localhost peers (sorted by longest uptime).
Block-relay-only connections exist as a protection against eclipse attacks, by
creating a path for block propagation that may be unknown to adversaries.
Protect against inbound peer connection slot attacks from disconnecting such
peers by attempting to protect up to 8 peers that are not relaying transactions
but have provided us with blocks.
Thanks to gmaxwell for suggesting these strategies.
