It moves the RelayTransaction() function to be a member function of the PeerManager class. This is required in order to move the transaction inventory data into the Peer object, since Peer objects are only accessible from within PeerManager.

2021-03-04[net processing] Don't pass CConnman to RelayTransactionsJohn Newbery
Use the local m_connman instead
2021-03-04[net processing] Move RelayTransaction into PeerManagerJohn Newbery
We don't mark RelayTransaction as const. Even though it doesn't mutate PeerManagerImpl state, it _is_ mutating the internal state of a CNode object, by updating setInventoryTxToSend. In a subsequent commit, that field will be moved to the Peer object, which is owned by PeerMangerImpl. This requires PeerManagerImpl::ReattemptInitialBroadcast() to no longer be const.

2020-12-10Periodically make block-relay connections and sync headersSuhas Daftuar
To make eclipse attacks more difficult, regularly initiate outbound connections and stay connected long enough to sync headers and potentially learn of new blocks. If we learn a new block, rotate out an existing block-relay peer in favor of the new peer. This augments the existing outbound peer rotation that exists -- currently we make new full-relay connections when our tip is stale, which we disconnect after waiting a small time to see if we learn a new block. As block-relay connections use minimal bandwidth, we can make these connections regularly and not just when our tip is stale. Like feeler connections, these connections are not aggressive; whenever our timer fires (once every 5 minutes on average), we'll try to initiate a new block-relay connection as described, but if we fail to connect we just wait for our timer to fire again before repeating with a new peer.

2020-10-27Avoid calling CAddrMan::Connected() on block-relay-only peer addressesSuhas Daftuar
Connected() updates the time we serve in addr messages, so avoid leaking block-relay-only peer connections by avoiding these calls.
2020-10-12Change transaction request logic to use txrequestPieter Wuille
This removes most transaction request logic from net_processing, and replaces it with calls to a global TxRequestTracker object. The major changes are: * Announcements from outbound (and whitelisted) peers are now always preferred over those from inbound peers. This used to be the case for the first request (by delaying the first request from inbound peers), and a bias afters. The 2s delay for requests from inbound peers still exists, but after that, if viable outbound peers remain for any given transaction, they will always be tried first. * No more hard cap of 100 in flight transactions per peer, as there is less need for it (memory usage is linear in the number of announcements, but independent from the number in flight, and CPU usage isn't affected by it). Furthermore, if only one peer announces a transaction, and it has over 100 in flight and requestable already, we still want to request it from them. The cap is replaced with an additional 2s delay (possibly combined with the existing 2s delays for inbound connections, and for txid peers when wtxid peers are available). Includes functional tests written by Marco Falke and Antoine Riard.

It has since grown to contain much of net_processing's logic. Therefore rename it to reflect its responsibilities.

2020-09-07[net_processing] Pass chainparams to PeerLogicValidation constructorJohn Newbery
Keep a references to chainparams, rather than calling the global Params() function every time it's needed. This is fine, since globalChainParams does not get updated once it's been set, and it's available at the point of constructing the PeerLogicValidation object.
2020-09-07[move only] Collect all private members of PeerLogicValidation togetherJohn Newbery
We don't have a project style for ordering class members, but it always makes sense to have no more than one of each public/protected/private specifier. Also move documentation for MaybeDiscourageAndDisconnect to the header.

This PR adds a third struct `Peer`, which is for p2p application layer data, and doesn't require cs_main. Eventually all application layer data from `CNode` should be moved to `Peer`, and any data that doesn't strictly require cs_main should be moved from `CNodeState` to `Peer` (probably all of `CNodeState` eventually). `Peer` objects are stored as shared pointers in a net processing global map `g_peer_map`, which is protected by `g_peer_mutex`. To use a `Peer` object, `g_peer_mutex` is locked, a copy of the shared pointer is taken, and the lock is released. Individual members of `Peer` are protected by different mutexes that guard related data. The lifetime of the `Peer` object is managed by the shared_ptr refcount. This PR adds the `Peer` object and moves the misbehaving data from `CNodeState` to `Peer`. This allows us to immediately remove 15 `LOCK(cs_main)` instances.
