f305cf77b6 Multiple fixes and optimizations for LLMQs and ChainLocks (#2724)
* Indicate success when signing was unnecessary

* Fix typo in name of LLMQ_400_60

* Move RemoveAskFor call for CLSIGs into ProcessNewChainLock

In case we got INV items for the same CLSIG that we recreated through
HandleNewRecoveredSig, (re-)requesting of the CLSIG from other peers
becomes unnecessary.

* Move Cleanup() call in CChainLocksHandler::UpdatedBlockTip up

We bail out early in a few situations from this method, so that Cleanup()
might not be called while its at the bottom.

* Bail out from CChainLocksHandler::UpdatedBlockTip if we already got the CLSIG

* Call RemoveAskFor when QFCOMMITMENT was received

Otherwise we might end up re-requesting it for a very long time when the
commitment INV was received shortly before it got mined.

* Call RemoveSigSharesForSession when a recovered sig is received

Otherwise we end up with session data in node states lingering around until
a fake "timeout" occurs (can be seen in the logs).

* Better handling of false-positive conflicts in CSigningManager

The old code was emitting a lot of messages in logs as it treated sigs
for exactly the same session as a conflict. This commit fixes this by
looking at the signHash before logging.

Also handle a corner-case where a recovered sig might be deleted between
the HasRecoveredSigForId and GetRecoveredSigById call.

* Don't run into session timeout when sig shares come in slow

Instead of just tracking when the first share was received, we now also
track when the last (non-duplicate) share was received. Sessios will now
timeout 5 minutes after the first share arrives, or 1 minute after the last
one arrived.

Implement new algo for quorum connections (#2710)

6da341379d Use smaller LLMQs for ChainLocks on testnet and devnet (#2669)
* Move llmqChainLocks initialization closer to other LLMQ related assignments

* Use smaller LLMQs for ChainLocks on testnet and devnet

We very often don't have enough MNs on testnet so we should use a smaller
quorum quorum for ChainLocks.

0c9fb69687 Harden spork15 on testnet (#2586)
* Replace IsDeterministicMNsSporkActive with IsDIP3Active

IsDIP3Active will now use a fixed parameter from consensus params.
Values for DIP0003Height/DIP0003Hash need to be updated when spork15
activates on mainnet.

Also enforce correct block hash on testnet/mainnet for DIP3 activation
block.

* Remove SPORK_15_DETERMINISTIC_MNS_ENABLED

* Replace all uses of IsDeterministicMNsSporkActive with IsDIP3Active

* Remove DIP3 upgrade-path tests and directly start with DIP3 enabled tests

* Make -masternodeprivkey non-mandatory

Implement and enforce DIP6 commitments (#2477)
* Add LLMQ parameters to consensus params

* Add DIP6 quorum commitment special TX

* Implement CQuorumBlockProcessor which validates and handles commitments

* Add quorum commitments to new blocks

* Propagate QFCOMMITMENT messages to all nodes

* Allow special transactions in blocks which have no inputs/outputs

But only for TRANSACTION_QUORUM_COMMITMENT for now.

* Add quorum commitments to self-crafted blocks in DIP3 tests

* Add simple fork logic for current testnet

This should avoid a fork on the current testnet. It only applies to the
current chain which activated DIP3 at height 264000 and block
00000048e6e71d4bd90e7c456dcb94683ae832fcad13e1760d8283f7e89f332f.

When we revert the chain to retest the DIP3 deployment, this fork logic
can be removed again.

* Use quorumVvecHash instead of quorumHash to make null commitments unique

Implementation of https://github.com/dashpay/dips/pull/31

* Re-add quorum commitments after pruning mempool selected blocks

* Refactor CQuorumBlockProcessor::ProcessBlock to have less nested if/else statements

Also add BEGIN/END markers for temporary code.

* Add comments/documentation to LLMQParams

* Move code which determines if a commitment is required into IsCommitmentRequired

This should make the code easier to read and also removes some duplication.

The also changes the error types that are possible from 3 to 2 now. Instead
of having "bad-qc-already-mined" and "bad-qc-not-mining-phase", there is
only "bad-qc-not-allowed" now.

* Use new parameter from consensus parames for the temporary fork

* Add consensus params for temporary hard-fork on testnet

This hard-fork is required on testnet as we have to fix a few consensus
bugs in DIP3/DIP4. It will also be required to introduce LLMQ commitments
to testnet.

* Add temporary fork-logic for testnet, which sets confirmedHash to null

...before fork activation. Otherwise we'd invalidate all DIP3 blocks on
testnet.

28a6007a40 Prepare DIP3 for testnet and reuse DIP3 deployment for autoix deployment (#2389)
* Add BIP9 parameters for DIP3 deployment on testnet

* Remove autoix BIP9 deployment and reuse DIP3 deployment

* Add BIP9CheckMasternodesUpgraded to chain params

This controls if miners should check for upgraded masternodes first before
adding BIP9 bits to the block version. This only makes sense in network
where masternodes are up and running before BIP9 activation, which is not
necessarely the case in regtest and devnet.

Also refactor ComputeBlockVersion to use fCheckMasternodesUpgraded instead
of the inverse fAssumeMasternodeIsUpgraded. It is set to false by default
and only set to true in CreateNewBlock.

* Check for upgraded masternodes for DIP3 activation (only mainnet and testnet)

* Bump PROTOCOL_VERSION and DMN_PROTO_VERSION

We probably have nodes with 70211 already running on testnet.

* add locktransaction rpc call

* Remove special instantsend fee for simple transactions

* Function to check if trx is simple enough to be autolocked

* Automatic lock for all received from peers simple trxes

If we get a new transaction with CInv message and it is "simple" and
is accepted in mempool, we initiate its lock. We don't lock orphan trxes

A pack of small fixes (#1992)
* Make sure gobject collateral was mined

`CGovernanceObject::IsCollateralValid()` would still fail for non-mined collateral later trying to check confirmations

* Fix powLimit for mainnet/testnet

That's a legacy thing, slightly rising it to match the actual bit-shifted value has no effect because real values are already lower.
Also clarify values for all networks in comments.

* Check for script addresses in CSuperblock::ParsePaymentSchedule()

Sentinel should already be downvoting such triggers if they would exist, no need to store/relay them.

* Do not process already known valid vote twice in CGovernanceObject::ProcessVote()

This should be handled by `CGovernanceManager::ProcessVote()` but imo it's better to have this at the `CGovernanceObject::ProcessVote()` level as well.

* Make sure CGovernanceObjectVoteFile::AddVote() never adds/updates already known votes

The way `CGovernanceObjectVoteFile::AddVote()` is used (i.e. wrapped in `CGovernanceObjectVoteFile::HasVote()` condition) it's already the case. Hoever nothing would guarantee consistency if it would be used elsewhere without such wrapper, so it's better to have similar check inside.

* Do not even try mnb recovery when -connect is set

`CConnman::ThreadOpenMasternodeConnections()` thread won't even start when `-connect` is set, so no need to ask for recovery, there is nothing that is going to be able to process such request.

* No need for SIGHASH_ANYONECANPAY in PS collateral signature

Collateral is just a normal tx created and signed by each participant individually, there is no need for special sig types.

* Release semMasternodeOutbound in CConnman::Interrupt()

Re-align Dash code with Bitcoin.

611879aa6d Use spork addresses instead of raw keys and allow changing them on startup (#1969)

* Use Dash addresses instead of raw public keys for sporks

The spork addresses are identical to the previously used public keys.

Also use CKeyID/CKey directly inside CSporkManager instead of parsing the
addresses/keys over and over. The default spork key (from chainparams) is
initialized with InitDefaultSporkAddress(). SetPrivKey parses the private
key now and stores it in sporkPrivKey instead of parsing it in
CSporkMessage::Sign().

cd9c6994c2 Implement named devnets (#1791)
* Initial devnet

* Move genesis block adding into its own method

* Introduce -allowprivatenet to lift limitation on RFC1918 addresses

Normally, RFC1918 (192.168.x.x/10.x.x.x/...) addresses are not allowed
to be relayed. Also, masternodes won't start when the address is considered
invalid.

This is needed to test local devnet or regtest based networks.

* Lift the requirement of minimum MN age for regtest/devnet

* Implement named devnets

This allows the creation of multiple independent devnets. Each one is
identified by a name which is hardened into a "devnet genesis" block,
which is automatically positioned at height 1. Validation rules will
ensure that a node from devnet=test1 never be able to accept blocks
from devnet=test2. This is done by checking the expected devnet genesis
block.

The genesis block of the devnet is the same as the one from regtest. This
starts the devnet with a very low difficulty, allowing us to fill up
needed balances for masternodes very fast.

Also, the devnet name is put into the sub-version of the VERSION message.
If a node connects to the wrong network, it will immediately be disconnected.

* Allow to select multiple addresses from the same group in devnet/regtest

The selection code normally only allows to select addresses from the same
group (e.g. 192.168.x.x) once. This results in connecting to only a single
node in devnet/regtest.

* Show the devnet name in the title bar and on the loading screen

* Add AllowMultipleAddressesFromGroup to chainparams and use it in net.cpp

* Remove unused/unneeded scripts from devnet geneses creation

1. OP_RETURN not needed in input script of devnet genesis
2. genesisOutputScript was unused

* Fix copy/paste error in -allowprivatenet description

* Improve -devnet parameter error handling

- Only allow one of -devnet, -regtest or -testnet
- Only allow -devnet=name to be specified once

* Use different datadir for each devnet

* Fix `devnet-devnet` issue

* Fix devnet splashscreen (should use testnet img)

* Avoid passing devNetName around (most of the time)

* Remove nMaxTipAge from CDevNetParams

169afafd50 Fix duplicate headers download in initial sync (#1589)
* Fix duplicate headers download in initial sync

Now that initial block download is delayed until the headers sync is done,
it was noticed that the initial headers sync may happen multiple times in
parallel in the case new blocks are announced. This happens because for
every block in INV that is received, a getheaders message is immediately
sent out resulting in a full download of the headers chain starting from
the point of where the initial headers sync is currently at. This happens
once for each peer that announces the new block. This slows down the
initial headers sync and increases the chance of another block being
announced before it is finished, probably leading to the same behavior
as already described, slowing down the sync even more...and so on.

This commit delays sending of GETHEADERS to later in case the chain is too
far behind while a new block gets announced. Header chains will still be
downloaded multiple times, but the downloading will start much closer
to the tip of the chain, so the damage is not that bad anymore.

This ensures that we get all headers from all peers, even if any of them
is on another chain. This should avoid what happened in
https://github.com/bitcoin/bitcoin/pull/8054
which needed to be reverted later.

This fixes the Bitcoin issue https://github.com/bitcoin/bitcoin/issues/6755

* Introduce DelayGetHeadersTime chain param and fix tests

The delaying of GETHEADERS in combination with very old block times in
test cases resulted in the delaying being triggered when the first newly
mined block arrives. This results in a completely stalled sync.

This is fixed by avoiding delaying in when running tests.

* Disconnect peers which are not catched up

Peers which stop sending us headers too early are very likely peers which
did not catch up before and stalled for some reason. We should disconnect
these peers and chose another one to continue.

ccee103a0e Backport "assumed valid blocks" feature from Bitcoin 0.13 (#1582)
* IBD check uses minimumchain work instead of checkpoints.

This introduces a 'minimum chain work' chainparam which is intended
 to be the known amount of work in the chain for the network at the
 time of software release.  If you don't have this much work, you're
 not yet caught up.

This is used instead of the count of blocks test from checkpoints.

This criteria is trivial to keep updated as there is no element of
subjectivity, trust, or position dependence to it. It is also a more
reliable metric of sync status than a block count.

* Remove GetTotalBlocksEstimate and checkpoint tests that test nothing.

GetTotalBlocksEstimate is no longer used and it was the only thing
 the checkpoint tests were testing.

Since checkpoints are on their way out it makes more sense to remove
 the test file than to cook up a new pointless test.

# Conflicts:
#	src/Makefile.test.include
#	src/test/Checkpoints_tests.cpp

* IsInitialBlockDownload no longer uses header-only timestamps.

This avoids a corner case (mostly visible on testnet) where bogus
 headers can keep nodes in IsInitialBlockDownload.

* Delay parallel block download until chain has sufficient work

nMinimumChainWork is an anti-DoS threshold; wait until we have a proposed
tip with more work than that before downloading blocks towards that tip.

* Add timeout for headers sync

At startup, we choose one peer to serve us the headers chain, until
our best header is close to caught up.  Disconnect this peer if more
than 15 minutes + 1ms/expected_header passes and our best header
is still more than 1 day away from current time.

* Introduce assumevalid setting to skip presumed valid scripts.

This disentangles the script validation skipping from checkpoints.

A new option is introduced "assumevalid" which specifies a block whos
 ancestors we assume all have valid scriptsigs and so we do not check
 them when they are also burried under the best header by two weeks
 worth of work.

Unlike checkpoints this has no influence on consensus unless you set
 it to a block with an invalid history.  Because of this it can be
 easily be updated without risk of influencing the network consensus.

This results in a massive IBD speedup.

This approach was independently recommended by Peter Todd and Luke-Jr
 since POW based signature skipping (see PR#9180) does not have the
 verifiable properties of a specific hash and may create bad incentives.

The downside is that, like checkpoints, the defaults bitrot and older
 releases will sync slower.  On the plus side users can provide their
 own value here, and if they set it to something crazy all that will
 happen is more time will be spend validating signatures.

Checkblocks and checklevel are also moved to the hidden debug options:
 Especially now that checkblocks has a low default there is little need
 to change these settings, and users frequently misunderstand them as
 influencing security or IBD speed.  By hiding them we offset the
 space added by this new option.

* Add consensusParams to FindNextBlocksToDownload

* Adjust check in headers timeout logic to align with 144 blocks in Dash
