afe42bd422 Merge #14287: tests: Use MakeUnique to construct objects owned by unique_ptrs
b6718e373e tests: Use MakeUnique to construct objects owned by unique_ptrs (practicalswift)

Pull request description:

  A subset of #14211 ("Use MakeUnique to construct objects owned by unique_ptrs") as suggested by @MarcoFalke in https://github.com/bitcoin/bitcoin/pull/14211#issuecomment-423324019.

  Use `MakeUnique` to construct objects owned by `unique_ptr`s.

  Rationale:
  * `MakeUnique` ensures exception safety in complex expressions.
  * `MakeUnique` gives a more concise statement of the construction.

Merge #15051: Tests: IsReachable is the inverse of IsLimited (DRY). Includes unit tests
6dc4593db1ccfb8745b2daa42f457981ae08dba9 IsReachable is the inverse of IsLimited (DRY). Includes unit tests (marcaiaf)

Pull request description:

  IsReachable is the inverse of IsLimited, but the implementation is duplicated (DRY)

  - Changed the implementation accordingly.
  - Added unit tests to document behavior and relationship
  - My modification in net.cpp  applies only to IsReachable.
  - Applied clang-format-diffpy

  Created new pull request to avoid the mess with:
  https://github.com/bitcoin/bitcoin/pull/15044

  Checked with supposedly conflicting PRs mentioned in the old PR. No conflicts with the specific changes in this PR.

  Do not share functions that are meant to be translation unit local with other translation units. Use internal linkage for those consistently.

Merge #12740: Add native support for serializing char arrays without FLATDATA
a7c45bc Add native support for serializing char arrays without FLATDATA (Pieter Wuille)

Pull request description:

  Support is added to serialize arrays of type `char` or `unsigned char` directly, without any wrappers. All invocations of the `FLATDATA` wrappers that are obsoleted by this are removed.

  This includes a patch by @ryanofsky to make `char` casting type safe.

  The serialization of `CSubNet` is changed to serialize a `bool` directly rather than though `FLATDATA`. This makes the serialization independent of the size of the bool type (and will use 1 byte everywhere).

  This is a small change taken from #10785.

8ebbef016928811756e46b9086067d1c826797a8 add test demonstrating addrLocal UB (Kaz Wesley)

Pull request description:

  Reachable from either place where SetIP is used when all of:
  - our best-guess addrLocal for a peer is IPv4
  - the peer tells us it's reaching us at an IPv6 address
  - NET logging is enabled

  In that case, SetIP turns an IPv4 address into an IPv6 address without
  setting the scopeId, which is subsequently read in GetSockAddr during
  CNetAddr::ToStringIP and passed to getnameinfo. Fix by ensuring every
  constructor initializes the scopeId field with something.

non-fully-connected nodes. If there's a match, assume we've connected
to ourself.

* net: move messageHandlerCondition to CConnman

* net: move send/recv statistics to CConnman

* net: move SendBufferSize/ReceiveFloodSize to CConnman

* net: move nLocalServices/nRelevantServices to CConnman

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).

* net: move semOutbound and semMasternodeOutbound to CConnman

* net: SocketSendData returns written size

* net: move max/max-outbound to CConnman

* net: Pass best block known height into CConnman

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.

* net: pass CClientUIInterface into CConnman

* net: Drop StartNode/StopNode and use CConnman directly

* net: Introduce CConnection::Options to avoid passing so many params

* net: add nSendBufferMaxSize/nReceiveFloodSize to CConnection::Options

* net: move vNodesDisconnected into CConnman

* Made the ForEachNode* functions in src/net.cpp more pragmatic and self documenting

* Convert ForEachNode* functions to take a templated function argument rather than a std::function to eliminate std::function overhead

* net: move MAX_FEELER_CONNECTIONS into connman

d934ffb2ff Added feeler connections increasing good addrs in the tried table. (#1530)
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.
