* Remove mapOrphanTransactionsByPrev from DoS_testsPieter Wuille2016-12-051-2/+0
| | | | | | | | 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.

* net: handle version push in InitializeNodeCory Fields2016-11-031-4/+4
|
* connman is in charge of pushing messagesCory Fields2016-11-031-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* net: Use deterministic randomness for CNode's nonce, and make it constCory Fields2016-10-311-4/+4

|
* net: Pass best block known height into CConnmanCory Fields2016-09-081-4/+4
| | | | | | | | | | | | | | | | | | | | 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: move nLocalServices/nRelevantServices to CConnmanCory Fields2016-09-081-4/+4
| | | | | 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).

| | | | | | | | | | Although this increases node memory usage in the worst case by perhaps 30MB, the current behavior causes severe issues with dependent tx relay.

* | Replace trickle nodes with per-node/message Poisson delaysPieter Wuille2015-12-111-7/+7
|/ | | | | | | | | | | | | | 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.

* | Split up util.cpp/hWladimir J. van der Laan2014-08-261-0/+1
|/ | | | | | | | | | | | | | | | Split up util.cpp/h into: - string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach) - money utilities (parsesmoney, formatmoney) - time utilities (gettime*, sleep, format date): - and the rest (logging, argument parsing, config file parsing) The latter is basically the environment and OS handling, and is stripped of all utility functions, so we may want to rename it to something else than util.cpp/h for clarity (Matt suggested osinterface). Breaks dependency of sha256.cpp on all the things pulled in by util.
* Remove timing-based signature cache unit testGavin Andresen2014-06-251-87/+0
| | | | | | | | | | | | | | | | | Two changes: First removes a unit test that fails in my development environment (OSX, compiled -g3 with clang). sipa says that's not terribly surprising; the CMutableTransaction change makes signing a little more expensive but verification quicker. The unit test timed sign+verify-uncached versus verify-cached-five-times. He also says the test will be invalid when libsec256kp1 is integrated (because validation is super-optimized over signing). core.h change fixes a compiler warning (clang -Wall : CMutableTransaction defined as struct, declared as class in script.h).

* Per-peer block download tracking and stalled download detection.Pieter Wuille2014-02-081-1/+0
| | | | | | | | | Keep track of which block is being requested (and to be requested) from each peer, and limit the number of blocks in-flight per peer. In addition, detect stalled downloads, and disconnect if they persist for too long. This means blocks are never requested twice, and should eliminate duplicate downloads during synchronization.
* Add main-specific node statePieter Wuille2013-12-081-7/+19
