2017-06-05rpc: Add listen address to incoming connections in `getpeerinfo`Wladimir J. van der Laan
This adds the listening address on which incoming connections were received to the CNode and CNodeStats structures. The address is reported in `getpeerinfo`. This can be useful for distinguishing connections received on different listening ports (e.g. when using a different listening port for Tor hidden service connections) or different networks.

also once half of all outgoing nodes have our preferred flags, require only minimal flags from the rest.
2017-05-18Populate services in GetLocalAddressAlex Morcos
Previously if we didn't have any local addresses, GetLocalAddress would return 0.0.0.0 and then we'd swap in a peer's notion of our address in AdvertiseLocal, but then nServices would never get set.

2017-04-01Change LogAcceptCategory to use uint32_t rather than sets of strings.Gregory Maxwell
This changes the logging categories to boolean flags instead of strings. This simplifies the acceptance testing by avoiding accessing a scoped static thread local pointer to a thread local set of strings. It eliminates the only use of boost::thread_specific_ptr outside of lockorder debugging. This change allows log entries to be directed to multiple categories and makes it easy to change the logging flags at runtime (e.g. via an RPC, though that isn't done by this commit.) It also eliminates the fDebug global. Configuration of unknown logging categories now produces a warning.

2017-03-05build: cleanup: define MSG_DONTWAIT/MSG_NO_SIGNAL locallyWladimir J. van der Laan
Define MSG_DONTWAIT and MSG_NO_SIGNAL in the implementation files that use them (`net.cpp` and `netbase.cpp`), instead of compat.h which is included all over the place. This avoids putting them in the global namespace, as defining them as 0 is a hack that works for our specific usage, but it is not a general solution. Also makes sure they are defined only once so the `!defined(MSG_x)` guard can go.

2017-02-10net: fix a few races. Credit @TheBlueMattCory Fields
These are (afaik) all long-standing races or concurrent accesses. Going forward, we can clean these up so that they're not all individual atomic accesses. - Reintroduce cs_vRecv to guard receive-specific vars - Lock vRecv/vSend for CNodeStats - Make some vars atomic. - Only set the connection time in CNode's constructor so that it doesn't change

2017-02-02net: don't run callbacks on nodes that haven't completed the version handshakeCory Fields
Since ForEach* are can be used to send messages to all nodes, the caller may end up sending a message before the version handshake is complete. To limit this, filter out these nodes. While we're at it, may as well filter out disconnected nodes as well. Delete unused methods rather than updating them.
2017-02-02Fix super-unlikely race introduced in 236618061a445d2cb11e72Matt Corallo
Once the CNode has been added to vNodes, it is possible that it is disconnected+deleted in the socket handler thread. However, after that we now call InitializeNode, which accesses the pnode. helgrind managed to tickle this case (somehow), but I suspect it requires in immensely braindead scheduler.
