2017-02-13net: require a verack before responding to anything elseCory Fields
7a8c251901 made this logic hard to follow. After that change, messages would not be sent to a peer via SendMessages() before the handshake was complete, but messages could still be sent as a response to an incoming message. For example, if a peer had not yet sent a verack, we wouldn't notify it about new blocks, but we would respond to a PING with a PONG. This change makes the behavior straightforward: until we've received a verack, never send any message other than version/verack/reject. The behavior until a VERACK is received has always been undefined, this change just tightens our policy. This also makes testing much easier, because we can now connect but not send version/verack, and anything sent to us is an error.
2017-02-13net: parse reject earlierCory Fields
Prior to this change, all messages were ignored until a VERSION message was received, as well as possibly incurring a ban score. Since REJECT messages can be sent at any time (including as a response to a bad VERSION message), make sure to always parse them. Moving this parsing up keeps it from being caught in the if (pfrom->nVersion == 0) check below.
2017-02-13net: correctly ban before the handshake is completeCory Fields
7a8c251901 made a change to avoid getting into SendMessages() until the version handshake (VERSION + VERACK) is complete. That was done to avoid leaking out messages to nodes who could connect, but never bothered sending us their version/verack. Unfortunately, the ban tally and possible disconnect are done as part of SendMessages(). So after 7a8c251901, if a peer managed to do something bannable before completing the handshake (say send 100 non-version messages before their version), they wouldn't actually end up getting disconnected/banned. That's fixed here by checking the banscore as part of ProcessMessages() in addition to SendMessages().

2017-02-10Use importmulti timestamp when importing watch only keysRussell Yanofsky
When importing a watch-only address over importmulti with a specific timestamp, the wallet's nTimeFirstKey is currently set to 1. After this change, the provided timestamp will be used and stored as metadata associated with watch-only key. This can improve wallet performance because it can avoid the need to scan the entire blockchain for watch only addresses when timestamps are provided. Also adds timestamp to validateaddress return value (needed for tests). Fixes #9034.
2017-02-10Dedup nTimeFirstKey update logicRussell Yanofsky
Also make nTimeFirstKey member variable private. This is just a cleanup change, it doesn't change behavior in any significant way.
2017-02-10Use MTP for importmulti "now" timestampsRussell Yanofsky
2017-02-10Add test to check new importmulti "now" valueRussell Yanofsky
Easiest way to test this was to expose the timestamp via the validateaddress RPC (which was already looking up and returning key metadata).
2017-02-10Require timestamps for importmulti keysRussell Yanofsky
Additionally, accept a "now" timestamp, to allow avoiding rescans for keys which are known never to have been used. Note that the behavior when "now" is specified is slightly different than the previous behavior when no timestamp was specified at all. Previously, when no timestamp was specified, it would avoid rescanning during the importmulti call, but set the key's nCreateTime value to 1, which would not prevent future block reads in later ScanForWalletTransactions calls. With this change, passing a "now" timestamp will set the key's nCreateTime to the current block time instead of 1. Fixes #9491

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

2017-02-07bench: Fix initialization order in registrationWladimir J. van der Laan
The initialization order of global data structures in different implementation units is undefined. Making use of this is essentially gambling on what the linker does, the so-called [Static initialization order fiasco](https://isocpp.org/wiki/faq/ctors#static-init-order). In this case it apparently worked on Linux but failed on OpenBSD and FreeBSD. To create it on first use, make the registration structure local to a function. Fixes #8910.
