* banlist: log post-swept banlist size at startupfanquake2020-07-081-1/+1
| | | | | We are currently logging the size of the banlist before SweepBanned() has been called, meaning the value may be incorrect.

* Replace automatic bans with discouragement filterPieter Wuille2020-07-031-4/+9
| | | | | | | | | | | | | | | | | | | | This patch improves performance and resource usage around IP addresses that are banned for misbehavior. They're already not actually banned, as connections from them are still allowed, but they are preferred for eviction if the inbound connection slots are full. Stop treating these like manually banned IP ranges, and instead just keep them in a rolling Bloom filter of misbehaving nodes, which isn't persisted to disk or exposed through the ban framework. The effect remains the same: preferred for eviction, avoided for outgoing connections, and not relayed to other peers. Also change the name of this mechanism to better reflect reality; they're not banned, just discouraged. Contains release notes and several interface improvements by John Newbery.

* Allow connections from misbehavior banned peers.Gregory Maxwell2019-01-221-2/+25
| | | | | | | | | | | | | | | | | | | | | | This allows incoming connections from peers which are only banned due to an automatic misbehavior ban if doing so won't fill inbound. These peers are preferred for eviction when inbound fills, but may still be kept if they fall into the protected classes. This eviction preference lasts the entire life of the connection even if the ban expires. If they misbehave again they'll still get disconnected. The main purpose of banning on misbehavior is to prevent our connections from being wasted on unhelpful peers such as ones running incompatible consensus rules. For inbound peers this can be better accomplished with eviction preferences. A secondary purpose was to reduce resource waste from repeated abuse but virtually any attacker can get a nearly unlimited supply of addresses, so disconnection is about the best we can do.
