2017-11-02Use a sensible default for blockmaxweightMatt Corallo
No sensible user will ever keep the default settings here, so not having sensible defaults only serves to screw users who are paying less attention, which makes for terrible defaults. Github-Pull: #11100 Rebased-From: 3dc263c9b9068ee9793b6c7a0023eff16d70fb8f
2017-11-02Deprecate confusing blockmaxsize, fix getmininginfo outputMatt Corallo
* This removes block-size-limiting code in favor of GBT clients doing the limiting themselves (if at all). * -blockmaxsize is deprecated and only used to calculate an implied blockmaxweight, addressing confusion from multiple users. * getmininginfo's currentblocksize return value was returning garbage values, and has been removed, also removing a GetSerializeSize call in some block generation inner loops and potentially addressing some performance edge cases.

2017-11-02Reject headers building on invalid chains by tracking invalidityMatt Corallo
This tracks the set of all known invalid-themselves blocks (ie blocks which we attempted to connect but which were found to be invalid). This is used to cheaply check if new headers build on an invalid chain. While we're at it we also resolve an edge-case in invalidateblock on pruned nodes which results in them needing a reindex if they fail to reorg.

2017-11-02Accept unrequested blocks with work equal to our tipMatt Corallo
This is a simple change that makes our accept requirements the same as our request requirements, (ever so slightly) further decoupling our consensus logic from our FindNextBlocksToDownload logic in net_processing. Github-Pull: #11531 Rebased-From: 932f118e6a3779bb3d6c3cc83963cf34ac150e42
2017-11-02Stop always storing blocks from whitelisted peersMatt Corallo
There is no reason to wish to store blocks on disk always just because a peer is whitelisted. This appears to be a historical quirk to avoid breaking things when the accept limits were added. Github-Pull: #11531 Rebased-From: 3d9c70ca0fd5d42f31114b689714af1825f0ed30
2017-11-02net: Add missing lock in ProcessHeadersMessage(...)practicalswift
Reading the variable mapBlockIndex requires holding the mutex cs_main. The new "Disconnect outbound peers relaying invalid headers" code added in commit 37886d5e2f9992678dea4b1bd893f4f10d61d3ad and merged as part of #11568 two days ago did not lock cs_main prior to accessing mapBlockIndex.

2017-11-02moveonly: factor out headers processing into separate functionSuhas Daftuar

2017-11-02Permit disconnection of outbound peers on bad/slow chainsSuhas Daftuar
Currently we have no rotation of outbound peers. If an outbound peer stops serving us blocks, or is on a consensus-incompatible chain with less work than our tip (but otherwise valid headers), then we will never disconnect that peer, even though that peer is using one of our 8 outbound connection slots. Because we rely on our outbound peers to find an honest node in order to reach consensus, allowing an incompatible peer to occupy one of those slots is undesirable, particularly if it is possible for all such slots to be occupied by such peers. Protect against this by always checking to see if a peer's best known block has less work than our tip, and if so, set a 20 minute timeout -- if the peer is still not known to have caught up to a chain with as much work as ours after 20 minutes, then send a single getheaders message, wait 2 more minutes, and if a better header hasn't been received by then, disconnect that peer. Note: - we do not require that our peer sync to the same tip as ours, just an equal or greater work tip. (Doing otherwise would risk partitioning the network in the event of a chain split, and is also unnecessary.) - we pick 4 of our outbound peers and do not subject them to this logic, to be more conservative. We don't wish to permit temporary network issues (or an attacker) to excessively disrupt network topology. Github-Pull: #11490 Rebased-From: 5a6d00c6defc587e22c93e63029fdd538ce8858d
2017-11-02Disconnecting from bad outbound peers in IBDSuhas Daftuar
When in IBD, we'd like to use all our outbound peers to help us sync the chain. Disconnect any outbound peers whose headers have insufficient work. Github-Pull: #11490 Rebased-From: c60fd71a65e841efe187992f46c583a704cc37f5

2017-11-02net: use an interface class rather than signals for message processingCory Fields

2017-11-02Don't process unrequested, low-work blocksSuhas Daftuar
A peer could try to waste our resources by sending us unrequested blocks with low work, eg to fill up our disk. Since e2652002b6011f793185d473f87f1730c625593b we no longer request blocks until we know we're on a chain with more than nMinimumChainWork (our anti-DoS threshold), but we would still process unrequested blocks that had more work than our tip. This commit fixes that behavior. Github-Pull: #11458 Rebased-From: ce8cd7a7da9174ab151172fc0ce97b5164637cf3

2017-11-01Avoid opening copied wallet databases simultaneouslyRussell Yanofsky
Make sure wallet databases have unique fileids. If they don't, throw an error. BDB caches do not work properly when more than one open database has the same fileid, because values written to one database may show up in reads to other databases. Bitcoin will never create different databases with the same fileid, but users can create them by manually copying database files. BDB caching bug was reported by Chris Moore <dooglus@gmail.com> https://github.com/bitcoin/bitcoin/issues/11429 Fixes #11429 Github-Pull: #11476 Rebased-From: 478a89c1ef79a75275d1b508122c06eee9386b2d

2017-10-03Verify DBWrapper iterators are taking snapshotsMatt Corallo
The LevelDB docs seem to indicate that an iterator will not take snapshots (even providing instructions on how to do so yourself). In several of the places we use them, we assume snapshots to have been taken. In order to make sure LevelDB doesn't change out from under us (and to prevent the next person who reads the docs from having the same fright I did), verify that snapshots are taken in our tests.
