◆ AttemptToEvictConnection()

bool CConnman::AttemptToEvictConnection ( )
private

Try to find a connection to evict when the node is full.

Extreme care must be taken to avoid opening the node to attacker triggered network partitioning. The strategy used here is to protect a small number of peers for each of several distinct characteristics which are difficult to forge. In order to partition a node the attacker must be simultaneously better at all of them than honest peers.
