2017-09-06net: drop unused connman paramCory Fields
The copy in PeerLogicValidation can be used instead.
2017-09-06net: use an interface class rather than signals for message processingCory Fields
Drop boost signals in favor of a stateful class. This will allow the message processing loop to actually move to net_processing in a future step.
2017-09-06net: pass CConnman via pointer rather than referenceCory Fields
There are a few too many edge-cases here to make this a scripted diff. The following commits will move a few functions into PeerLogicValidation, where the local connman instance can be used. This change prepares for that usage.

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.

2016-12-05Remove mapOrphanTransactionsByPrev from DoS_testsPieter Wuille
This is another violation of the one definition rule, as the type for mapOrphanTransactionsByPrev did not match the one in net_processing.cpp anymore. As it now depends on a custom Iterator, it seems too much hassle to correctly expose it to the tests. Instead, this commit just removes the one test it was referenced in.

2016-11-03net: handle version push in InitializeNodeCory Fields
2016-11-03connman is in charge of pushing messagesCory Fields
The changes here are dense and subtle, but hopefully all is more explicit than before. - CConnman is now in charge of sending data rather than the nodes themselves. This is necessary because many decisions need to be made with all nodes in mind, and a model that requires the nodes calling up to their manager quickly turns to spaghetti. - The per-node-serializer (ssSend) has been replaced with a (quasi-)const send-version. Since the send version for serialization can only change once per connection, we now explicitly tag messages with INIT_PROTO_VERSION if they are sent before the handshake. With this done, there's no need to lock for access to nSendVersion. Also, a new stream is used for each message, so there's no need to lock during the serialization process. - This takes care of accounting for optimistic sends, so the nOptimisticBytesWritten hack can be removed. - -dropmessagestest and -fuzzmessagestest have not been preserved, as I suspect they haven't been used in years.

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).

(Gregory Maxwell) 11cc143 Adds an expiration time for orphan tx. (Gregory Maxwell) db0ffe8 This eliminates the primary leak that causes the orphan map to always grow to its maximum size.

2016-06-15Increase maximum orphan size to 100,000 bytes.Gregory Maxwell
Although this increases node memory usage in the worst case by perhaps 30MB, the current behavior causes severe issues with dependent tx relay.

2015-12-11Replace trickle nodes with per-node/message Poisson delaysPieter Wuille
We used to have a trickle node, a node which was chosen in each iteration of the send loop that was privileged and allowed to send out queued up non-time critical messages. Since the removal of the fixed sleeps in the network code, this resulted in fast and attackable treatment of such broadcasts. This pull request changes the 3 remaining trickle use cases by random delays: * Local address broadcast (while also removing the the wiping of the seen filter) * Address relay * Inv relay (for transactions; blocks are always relayed immediately) The code is based on older commits by Patrick Strateman.
