2016-09-08net: Pass best block known height into CConnmanCory Fields
CConnman then passes the current best height into CNode at creation time. This way CConnman/CNode have no dependency on main for height, and the signals only move in one direction. This also helps to prevent identity leakage a tiny bit. Before this change, an attacker could theoretically make 2 connections on different interfaces. They would connect fully on one, and only establish the initial connection on the other. Once they receive a new block, they would relay it to your first connection, and immediately commence the version handshake on the second. Since the new block height is reflected immediately, they could attempt to learn whether the two connections were correlated. This is, of course, incredibly unlikely to work due to the small timings involved and receipt from other senders. But it doesn't hurt to lock-in nBestHeight at the time of connection, rather than letting the remote choose the time.
2016-09-08net: move nLocalServices/nRelevantServices to CConnmanCory Fields
These are in-turn passed to CNode at connection time. This allows us to offer different services to different peers (or test the effects of doing so).

2016-09-08net: move nLocalHostNonce to CConnmanCory Fields
This behavior seems to have been quite racy and broken. Move nLocalHostNonce into CNode, and check received nonces against all non-fully-connected nodes. If there's a match, assume we've connected to ourself.

2016-08-25Do not add random inbound peers to addrman.Gregory Maxwell
We should learn about new peers via address messages. An inbound peer connecting to us tells us nothing about its ability to accept incoming connections from us, so we shouldn't assume that we can connect to it based on this. The vast majority of nodes on the network do not accept incoming connections, adding them will only slow down the process of making a successful connection in the future. Nodes which have configured themselves to not announce would prefer we not violate their privacy by announcing them in GETADDR responses.

2016-08-23Added feeler connections increasing good addrs in the tried table.Ethan Heilman
Tests if addresses are online or offline by briefly connecting to them. These short lived connections are referred to as feeler connections. Feeler connections are designed to increase the number of fresh online addresses in tried by selecting and connecting to addresses in new. One feeler connection is attempted on average once every two minutes. This change was suggested as Countermeasure 4 in Eclipse Attacks on Bitcoin’s Peer-to-Peer Network, Ethan Heilman, Alison Kendler, Aviv Zohar, Sharon Goldberg. ePrint Archive Report 2015/263. March 2015.
