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.
|
|
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.
|
|
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.
|
|
Removes checking whitelisted behavior (which will be removed, the
difference in behavior here makes little sense) and no longer
requires that blocks at the same work as our tip be dropped if not
requested (in part because we *do* request those blocks).

e065249 Add unit test for outbound peer eviction (Suhas Daftuar)
5a6d00c Permit disconnection of outbound peers on bad/slow chains (Suhas Daftuar)
c60fd71 Disconnecting from bad outbound peers in IBD (Suhas Daftuar)
Pull request description:
The first commit will disconnect an outbound peer that serves us a headers chain with insufficient work while we're in IBD.
The second commit introduces a way to disconnect outbound peers whose chains fall out of sync with ours:
For a given outbound peer, we check whether their best known block (which is known from the blocks they announce to us) has at least as much work as our tip. If it doesn't, we set a 20 minute timeout, and if we still haven't heard about a block with as much work as our tip had when we set the timeout, then we send a single getheaders message, and wait 2 more minutes. If after two minutes their best known block has insufficient work, we disconnect that peer.
We protect 4 of our outbound peers (who provide some "good" headers chains, ie a chain with at least as much work as our tip at some point) from being subject to this logic, to prevent excessive network topology changes as a result of this algorithm, while still ensuring that we have a reasonable number of nodes not known to be on bogus chains.
We also don't require our peers to be on the same chain as us, to prevent accidental partitioning of the network in the event of a chain split. Note that if our peers are ever on a more work chain than our tip, then we will download and validate it, and then either reorg to it, or learn of a consensus incompatibility with that peer and disconnect. This PR is designed to protect against peers that are on a less work chain which we may never try to download and validate.

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.
|
|
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.

sendheaders.py
6d51eaefe qa: Fix race condition in sendheaders.py (Suhas Daftuar)
c96b2e4f0 qa: Fix replace-by-fee race condition failures (Suhas Daftuar)
Pull request description:
I think #11407 broke replace-by-fee by introducing a race condition. I was observing frequent failures of replace-by-fee locally, always with a mempool sync failure (the sync call was added in #11407).
It appeared to me like there were two causes: sometimes the node would be in IBD and not request the transaction that was relayed; other times the blocks generated in make_utxo wouldn't have relayed quickly enough for the spend of the transaction to be accepted. I believe I've fixed both potential errors.
ping @instagibbs
Edit: I found a race condition in the sendheaders.py test, where if the verack from the python node wasn't processed before the first block in the test was generated, then no block announcement would go out to that peer, breaking the test. Fixed by adding a sync_with_ping after waiting for verack.

ce8cd7a Don't process unrequested, low-work blocks (Suhas Daftuar)
Pull request description:
A peer could try to waste our resources by sending us unrequested blocks with
low work (eg to fill up our disk). Since e265200 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 (which generally has low-work during IBD), even though we may not
yet have found a headers chain with sufficient work.
Fix this and add a test.

as 'already there'
258d33b41 [mempool] Mark unaccepted txs present in mempool as 'already there'. (Karl-Johan Alm)
Pull request description:
I was investigating the reasons for failed imports in mempool and noticed that `LoadMempool()` and `pwallet->postInitProcess()` (for all wallets) are executed concurrently. The wallet will end up importing transactions that `LoadMempool()` later tries to import; the latter will fail due to the tx already being in the mempool.
This PR changes the log message, adding an additional "already there" entry. For transactions not accepted into mempool, a check if they are in the mempool is done first, and if found, they are counted as 'already there', otherwise counted as 'failed'.
Also slight rewording for consistency (successes, failed, expired, ... -> succeeded, failed, expired).

43f76f6ac Add missing comma from rescanblockchain (MeshCollider)
Pull request description:
#7061 forgot a comma in the HelpExampleRpc() for the rescanblockchain RPC, giving an incorrect example command output:
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "rescanblockchain", "params": [100000 120000] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/
Was just missed during nit-fixing. This is a trivial fix to add that comma in.
