2d4327d net: Allow connecting to extra outbound peers (Suhas Daftuar)
Pull request description:
This is an alternative approach to #11534. Rather than disconnect an outbound peer when our tip looks stale, instead try to connect to an additional outbound peer.
Periodically, check to see if we have more outbound peers than we target (ie if any extra peers are in use), and if so, disconnect the one that least recently announced a new block (breaking ties by choosing the newest peer that we connected to).

Pull request description:
@sdaftuar pointed out that the version in #11487 was somewhat DoS-able as someone could feed you a valid chain that forked off the the last checkpoint block and force you to do lots of work just walking backwards across blocks for each new block they gave you. We came up with a few proposals but settled on the one implemented here as likely the simplest without obvious DoS issues. It uses our existing on-load mapBlockIndex walk to make sure everything that descends from an invalid block is marked as such, and then simply caches blocks which we attempted to connect but which were found to be invalid. To avoid DoS issues during IBD, this will need to depend on #11458.
Includes tests from #11487.

Add missing lock in `ProcessHeadersMessage(...)`.
Reading the variable `mapBlockIndex` requires holding the mutex `cs_main`.
The new "Disconnect outbound peers relaying invalid headers" code added in commit 37886d5e2f and merged as part of #11568 two days ago did not lock `cs_main` prior to accessing `mapBlockIndex`.

4637f1852 moveonly: factor out headers processing into separate function (Suhas Daftuar)
Pull request description:
Alternate to #11446.
Disconnect outbound (non-manual) peers that serve us block headers that are already known to be invalid, but exempt compact block announcements from such disconnects.
We restrict disconnection to outbound peers that are using up an outbound connection slot, because we rely on those peers to give us connectivity to the honest network (our inbound peers are not chosen by us and hence could all be from an attacker/sybil). Maintaining connectivity to peers that serve us invalid headers is sometimes desirable, eg after a soft-fork, to protect unupgraded software from being partitioned off the honest network, so we prefer to only disconnect when necessary.
Compact block announcements are exempted from this logic to comply with BIP 152, which explicitly permits nodes to relay compact blocks before fully validating them.

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.

Pull request description:
This was mostly written as a way to clean things up so that the NETWORK_LIMITED PR (#10387) can be simplified a ton, but its also a nice standalone cleanup that will also require a bit of review because it tweaks a lot of stuff across net. The new functions are fine in protocol.h right now since they're straight-forward, but after NETWORK_LIMITED will really want to move elsewhere after @theuni moves the nServices-based selection to addrman from connman.
Adds HasAllRelevantServices and GetRelevantServices, which check
for NETWORK|WITNESS.
This changes the following:
* Removes nRelevantServices from CConnman, disconnecting it a bit
more from protocol-level logic.
* Replaces our sometimes-connect-to-!WITNESS-nodes logic with
simply always requiring WITNESS|NETWORK for outbound non-feeler
connections (feelers still only require NETWORK).
* This has the added benefit of removing nServicesExpected from
CNode - instead letting net_processing's VERSION message
handling simply check HasAllRelevantServices.
* This implies we believe WITNESS nodes to continue to be a
significant majority of nodes on the network, but also because
we cannot sync properly from !WITNESS nodes, it is strange to
continue using our valuable outbound slots on them.
* In order to prevent this change from preventing connection to
-connect= nodes which have !WITNESS, -connect nodes are now
given the "addnode" flag. This also allows outbound connections
to !NODE_NETWORK nodes for -connect nodes (which was already true
of addnodes).
* Has the (somewhat unintended) consequence of changing one of the
eviction metrics from the same
sometimes-connect-to-!WITNESS-nodes metric to requiring
HasRelevantServices.
This should make NODE_NETWORK_LIMITED much simpler to implement.

yet have found a headers chain with sufficient work.

* Remove ppszTypeName from protocol.cpp and reimplement GetCommand
This removes the need to carefully maintain ppszTypeName, which required
correct order and also did not allow to permanently remove old message
types.
To get the command name for an INV type, GetCommandInternal uses a switch
which needs to be maintained from now on.
The way this is implemented also resembles the way it is implemented in
Bitcoin today, but it's not identical. The original PR that introduced the
switch case in Bitcoin was part of the Segwit changes and thus never got
backported. I decided to implement it in a slightly different way that
avoids throwing exceptions when an unknown INV type is encountered.
IsKnownType will now also leverage GetCommandInternal() to figure out if
the INV type is known locally. This has the side effect of old/legacy
message types to return false from now on. We will depend on this side
effect in later commits when we remove legacy InstantSend code.
* Stop handling/relaying legacy IX messages
When we receive an IX message, we simply treat it as a regular TX and relay
it as such.
We'll however still request IX messages when they are announced to us. We
can't simply revert to requesting TX messages in this case as it might
result in the other peer not answering due to the TX not being in mapRelay
yet. We should at some point in the future completely drop handling of IX
messages instead.

9aac9f90d5e56752cc6cbfac48063ad29a01143c replace modulus with FastMod (Martin Ankerl)
Pull request description:
Not sure if this is optimization is necessary, but anyway I have some spare time so here it is. This replaces the slow modulo operation with a much faster 64bit multiplication & shift. This works when the hash is uniformly distributed between 0 and 2^32-1. This speeds up the benchmark by a factor of about 1.3:
```
RollingBloom, 5, 1500000, 3.73733, 4.97569e-07, 4.99002e-07, 4.98372e-07 # before
RollingBloom, 5, 1500000, 2.86842, 3.81630e-07, 3.83730e-07, 3.82473e-07 # FastMod
```
Be aware that this changes the internal data of the filter, so this should probably
not be used for CBloomFilter because of interoperability problems.

* Use unordered_map in CSporkManager
In one of my profiling sessions with many InstantSend transactions
happening, calls into CSporkManager added up to about 1% of total CPU time.
This is easily avoidable by using unordered maps.
* Use std::unordered_map instead of std::map in limitedmap
* Use unordered_set for CNode::setAskFor
* Add serialization support for unordered maps and sets
* Use unordered_map for mapArgs and mapMultiArgs
* Let limitedmap prune in batches and use unordered_multimap
Due to the batched pruning, there is no need to maintain an ordered map
of values anymore. Only when nPruneAfterSize, there is a need to create
a temporary ordered vector of values to figure out what can be removed.
* Instead of using a multimap for mapAskFor, use a vector which we sort on demand
CNode::AskFor will now push entries into an initially unordered vector
instead of an ordered multimap. Only when we later want to use vecAskFor in
SendMessages, we sort the vector.
The vector will actually be mostly sorted in most cases as insertion order
usually mimics the desired ordering. Only the last few entries might need
some shuffling around. Doing the sort on-demand should be less wasteful
then trying to maintain correct order all the time.
* Fix compilation of tests
* Fix limitedmap tests
* Rename limitedmap to unordered_limitedmap to ensure backports conflict

* Sort evo/* source files in Makefile.am
* Keep track of proRegTxHash in CConnman::masternodeQuorumNodes map

* Fix serialization of std::tuple with const rvalue elements
Having serialization and deserialization in the same specialized template
results in compilation failures due to the "if(for_read)" branch.
* Implement MNAUTH message
This allows masternodes to authenticate themself.
* Protect fresh incoming connections for a second from eviction
Give fresh connections some time to do the VERSION/VERACK handshake and
an optional MNAUTH when it's a masternode. When an MNAUTH happened, the
incoming connection is then forever protected against eviction.
If a timeout of 1 second occurs or the first message after VERACK is not
MNAUTH, the node is not protected anymore and becomes eligable for
eviction.
* Avoid connecting to masternodes if an incoming connection is from the same one
Now that incoming connections from MNs authenticate them self, we can avoid
connecting to the same MNs through intra-quorum connections.
* Apply review suggestions
* Introduce "qsendrecsigs" to indicate that plain recovered sigs should be sent
Full nodes, including masternodes, will send this message automatically.
Other node implementations (e.g. SPV) are usually not interested and would
not send this message.
* Use std::atomic<bool> instead of std::atomic_bool
Not related to this PR, but a small enough change to include it here as
well.
* Don't rely on UTXO set in CheckCanLock
The UTXO set only works for TXs in the mempool and won't work when we try
to retroactively lock unlocked TXs from blocks.
This is safe as ProcessTx is only called when a TX was accepted into the
mempool or connected in a block, which means that all input checks were
good.
* Rename RetryLockMempoolTxs to RetryLockTxs and let it retry connected TXs
* Instead of manually calling ProcessTx, let SyncTransaction handle all cases
SyncTransaction is called from AcceptToMemoryPool and when transactions got
connected in a block. So this is the time we want to run TXs through
ProcessTx. This also enables retroactive signing of TXs that were unknown
before a new block appeared.
* Test retroactive signing and safe TXs in LLMQ ChainLocks tests
* Also test for retroactive signing of chained TXs
* Honor lockedParentTx when looking for TXs to retry signing
* Stop scanning for TXs to retry after a depth of 6
* Generate 6 block to avoid retroactive signing overloading Travis
* Avoid retroactive signing
* Don't rely on NewPoWValidBlock and use SyncTransaction to build blockTxs
NewPoWValidBlock is not guaranteed to be called when blocks come in fast.
When a block is accepted in AcceptBlock, NewPoWValidBlock is only called
when the new block is a successor of the currently active tip. This is not
the case when after the first block a second block is accepted immediately
as the first block is not connected yet.
This might be a bug actually in the handling of NewPoWValidBlock, so we
might need to check/fix this later, but currently I prefer to not touch
that part.
Instead, we now use SyncTransaction to gather TXs for blockTxs. This works
because SyncTransaction is called for all transactions in a freshly
connected block in one go. The call also happens before UpdatedBlockTip is
called, so it's fine with the existing logic.
* Use tx.IsCoinBase() instead of checking index 0
Also check for empty vin.
* Remove unused parameters from CInstantSendManager::ProcessTx
* Pass txHash in CheckCanLock by reference instead of pointer
* Dont' allow locking of TXs without inputs
* Remove unused local variable nInstantSendConfirmationsRequired
* Don't subtract 1 from nInstantSendConfirmationsRequired
This was necessary in the old system but is not necessary in the new system.
It also prevented proper retroactive signing of chained TXs in regtest as
it resulted in child TXs to return true immediately for CheckCanLock when
it should actually have waited for the parent TX to become locked first.
* Access chainActive.Height() while cs_main is locked
* Properly read and write lastChainLockBlock
"pindex" is NOT the chainlocked block after the while loop finishes. We
must use the pindex (renamed to pindexChainLock now) given on method entry.
Also, the GetLastChainLockBlock() result was not assigned to,
lastChainLockBlock which resulted in the while loop to run unnecessarily
long.
* Generalize filtering in NewPoWValidBlock and SyncTransaction
We're actually interested in all TXs that have inputs, so no need to
explicitly check for tx types.
* Use tx.IsCoinBase() instead of checking for index 0
* Handle cases where a TX is not received yet in wait_for_instantlock
* Wait on all nodes for the locks
Otherwise we end up with the sender having it locked but other nodes
not yet, failing the test.
* Fix LogPrintf call in CChainLocksHandler::DoInvalidateBlock
725b79a [test] Verify node doesn't send headers that haven't been fully validated (Russell Yanofsky)
3788a84 Do not send (potentially) invalid headers in response to getheaders (Matt Corallo)
Pull request description:
Nowhere else in the protocol do we send headers which are for
blocks we have not fully validated except in response to getheaders
messages with a null locator. On my public node I have not seen any
such request (whether for an invalid block or not) in at least two
years of debug.log output, indicating that this should have minimal
impact.

eff4bd8 [test] P2P functional test for certain fingerprinting protections (Jim Posen)
a2be3b6 [net] Ignore getheaders requests for very old side blocks (Jim Posen)
Pull request description:
Sending a getheaders message with an empty locator and a stop hash is a request for a single header by hash. The node will respond with headers for blocks not in the main chain as well as those in the main chain. To avoid fingerprinting, the node should, however, ignore requests for headers on side branches that are too old. This replicates the logic that currently exists for `getdata` requests for blocks.

c47f5b7 Cache witness-enabled state with recent-compact-block-cache (Matt Corallo)
efc135f Use cached [compact] blocks to respond to getdata messages (Matt Corallo)
Tree-SHA512: ffc478bddbf14b8ed304a3041f47746520ce545bdeffa9652eff2ccb25c8b0d5194abe72568c10f9c1b246ee361176ba217767af834752a2ca7263d292005e87
This seems to be backported wrongly. In the Bitcoin code, there is a
condition on requested witness data and we took the other branch which
recreates the compact block. We should have taken the other branch because
we always send with witness data (there is no Segwit in Dash).
* Add libbacktrace to depends
This is currently only useful to extract symbols. It fails to gather
stacktraces when compiled with MinGW, so we can only use it to get symbol
information from a stack trace which we gathered outside of libbacktrace.
* Add -mbig-obj to CXXFLAGS for MinGW builds
* Implement stacktraces for C++ exceptions
This is a hack and should only be used for debugging. It works by wrapping
the C++ ABI __wrap___cxa_allocate_exception. The wrapper records a backtrace
and stores it in a global map. Later the stacktrace can be retrieved with
GetExceptionStacktraceStr.
This commit also adds handlers to pretty print uncaught exceptions and
signals.
* Use GetPrettyExceptionStr for all unhandled exceptions
* Use --enable-stacktraces in CI for linux32/linux64
* Register exception translators to pretty print exceptions in unit tests
* Catch and print python exceptions when stopping nodes
Otherwise the code at the bottom is never executed when nodes crash,
leading to no output of debug.log files on Travis.
* Remove now unneeded/unused TestCrash methods
* Drop registry deletion of the old key
* Drop no longer used CGovernanceObjectVoteFile::RemoveOldVotes()
* Drop temporary disconnect code and bump min protos to 70213
* drop comment
* fix
* Split up remaining logic from CMasternodeMan into CMasternodeMetaMan and CMasternodeUtils
Also get rid of CMastermode and store remaining meta info
in CMasternodeMetaInfo
* Also allow non-const T in Serialize/Unserialize for shared_ptr
* Rename CActiveDeterministicMasternodeManager to CActiveMasternodeManager
* Fix nowallet compile in masternode-utils.cpp
* Remove CActiveLegacyMasternodeManager
* Remove sentinelping RPC
* Remove unused P2P messages and inv types
There are still places where these are used in the code. The next commits
will clean these up.
* Remove MNB/MNP/MNVERIFY related code from masternode(man).h/cpp
* Remove all legacy code regarding block MN payee voting
* Remove MASTERNODE_SYNC_LIST and MASTERNODE_SYNC_MNW states
Also replace all uses of IsMasternodeListSynced and IsWinnersListSynced
with IsBlockchainSynced.
* Remove unsupported masternode RPCs
* Remove UpdateLastPaid methods
* Remove duplicate deterministicmns.h include
* Remove masternode.conf support
* Remove legacy MN lists support from masternode list GUI
* Remove unnecessary AskForMN call
* Remove compatibility code in CPrivateSendQueue::GetSignatureHash
* Don't add locally calculated MN payee in case GetBlockTxOuts failed
This is not valid in DIP3 mode
* Remove check for IsDeterministicMNsSporkActive in "masternode status"
* Move CMasternode::IsValidNetAddr to CActiveDeterministicMasternodeManager
* Remove use of CMasternode::CheckCollateral in governance code
* Remove uses of MASTERNODE_SENTINEL_PING_MAX_SECONDS/MASTERNODE_SENTINEL_PING_MAX_SECONDS
* Remove support for "-masternodeprivkey"
* Remove pre-DIP3 vote cleanup
* Remove compatibility code for quorumModifierHash/masternodeProTxHash
* Remove check for invalid nBlockHeight in CMasternodePayments::GetBlockTxOuts
...and let it crash instead. We expect this method to be called with the
correct height now (after DIP3 was fully deployed).
* Remove ECDSA based Sign/CheckSignature from CGovernanceObject
Only masternodes sign governance objects, so there is no need for ECDSA
support here anymore.
* Always add superblock and MN reward payments into new block
* Always check block payees (except if fLiteMode==true)
* Always allow superblock and MN payees in same block
* Remove/Fix a few references to masternode.conf and related stuff
Also delete guide-startmany.md and masternode_conf.md
* Implement NotifyMasternodeListChanged signal and call governance maintenance
* Remove non-DIP3 code path from CMasternodeMan::Find
* Remove remaining unused code from CMasternode/CMasternodeMan
* Always load governance.dat on startup
* Mine an empty block instead of incrementing nHeight from chain tip in miner tests
This test is crashing otherwise in GetBlockTxOuts as it tries to access a
previous block that is not existing.
* Skip MN payments verification on historical blocks (pre-DIP3 blocks)
Even though DIP3 was active on BIP9 level, the spork was not active yet at
that point meaning that payments were not enforced at that time.
* Remove unused state and CollateralStatus enums
* Unconditionally return false from IsBlockPayeeValid when IsTransactionValid returns false
IsTransactionValid already handles the case where IsDIP3Active() returns
false, making it return true.
* Add override keyword to CDSNotificationInterface::NotifyMasternodeListChanged
* Fix help for masternodelist status (POSE_BANNED and no OUTPOINT_SPENT)
* 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
This code will vanish later.
* Bump PROTOCOL_VERSION and DMN_PROTO_VERSION to 70213
This will disconnect all nodes from the old testnet chain when DIP3 gets
activated through BIP9.
Also update comments where 70212/70213 was referenced.
* Also bump MIN_PEER_PROTO_VERSION_DIP3 and MIN_PRIVATESEND_PEER_PROTO_VERSION
* Implement creation and propagation of dummy contributions
These act as a ping which is broadcast a few blocks before the dummy
commitments are created. They are meant to determine online/offline members.
* Use information about received dummy contributions to determine validMembers
* Fix PoSe tests
* Fix dummy DKG phase progress in PoSe tests and give tests more time
Mine one block at a time until we reach the mining phase.
* Fix spork syncing issue in sporks tests
https://github.com/dashpay/dash/pull/2522 caused an issue with sporks syncing
in tests. The introduced time check in CMasternodeSync::ProcessTick causes
masternode sync to never start when mocktime is enabled, so this commit
disables mocktime for sporks.py.
Disabling mocktime however leads to fInitialDownload never becoming false
in CMasternodeSync::UpdatedBlockTip, so mnsync is never started. To fix
this, the tests now create a block before connecting the last node.
This however doesn't work because node1 will ignore the "getheaders" request
from node2 as it has not finished mnsync yet...so we also have to force
finish mnsync for node1.
* Also respond with getdata for announced sporks while in IBD
There was never a good reason to ignore spork announcements while in IBD.
At the same time, this poses the risk of missing out on sporks while in IBD.
This also fixes an issue in sporks testing, as nodes did not request for
announced sporks.
* Use wait_to_sync instead of custom loop
This is moving up the RemoveAskFor call above the ProcessTxLockRequest
call. If ProcessTxLockRequest fails, we should not re-request the same
TX/IX from other nodes as it will continue to fail.
* Move deserialization of REJECT message fields out of if(fDebug)
* Ban nodes which keep requesting and then rejecting blocks
* Don't read/deserialize reject hash twice
* Only use ban score of 1
* Add SPORK_17_QUORUM_DKG_ENABLED spork
* Implement CDummyDKG and CDummyCommitment until we have the real DKG merged
This is only used on testnet/devnet/regtest and will NEVER be used on
mainnet. It is NOT SECURE AT ALL!
See comment in quorums_dummydkg.h for more details.
* Test simple PoSe in DIP3 tests
* Generate 2 instead of 4 blocks per iteration in PoSe tests
4 was based on old chainparams where I used larger phases.
* Only sleep when necessary in PoSe tests
* Fix typo in comment
* Give PoSe tests more time and sync after fast-forward
* 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
* Implement RemoveAskFor to indicate that we're not interested in an item anymore
When an INV item is received from the first node, the item is requested
immediately. If the same item is received from another node, an entry is
added to mapAskFor which marks the item for re-requesting in case the first
node did not respond. When the item is received from the first node,
the item was previously never removed from mapAskFor. Only the later getdata
loop in SendMessages would then gradually remove items from the map. This
is quite delayed however as the entries in mapAskFor have a timeout value.
RemoveAskFor allows to remove all entries from mapAskFor and setAskFor
when we are not interested in the item anymore (e.g. because we received
it already).
* Call RemoveAskFor whenever we receive a message
* Only pass hash instead of CInv object to RemoveAskFor
* Use BLS keys for operator keys
* Add "bls generate" RPC to generate BLS keys
* Use unique_ptr to store blsKeyOperator and blsPubKeyOperator
Needed because the Chia BLS library crashes when keys are created before
the library is initialized, even if keys are not used. This is the case here
as we have static instances here.
* Remove unnecessary CheckSignature calls
This seems to be some garbage I left in by mistake.
* Fixed review comments
* Fix rpc help for operator keys
All keys that are used as examples are random. None of the secret keys
belongs to any of the public keys.
* Use .GetHash() instead of ::SerializeHash() for BLS pubkeys in txmempool.cpp
* Rename mapProTxBlsPubKeys to mapProTxBlsPubKeyHashes
* 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
that accepted in mempool after this trx because they are locked by other
peers.
* Automatically lock simple trxes in wallet
* protocol bump for InstantSend without special fee
* Add function to detect used mempool share
* Mempool threshold for auto IX locks
* Add SPORK_16_INSTANTSEND_AUTOLOCKS spork
* Make autolocks active only when spork SPORK_16_INSTANTSEND_AUTOLOCKS is active
* BIP9 autolocks activation
* revert increasing min peer protocol version for mn rank
* move IsTrxSimple check to CTxLockRequest class
* make MAX_INPUTS_FOR_AUTO_IX private member of CTxLockRequest class
* make AUTO_IX_MEMPOOL_THRESHOLD private member of CInstantSend class
* remove locktransaction RPC call
* tests for automatic IS locks
* fix mempool threshod calculation
* bump mocktime in activate_autoix_bip9

* remove rbf #include
* remove rbf in rpc-tests
* removes replace-by-fee.py
* remove help text related to rbf
* remove comment text relating to rbf
* remove "-mempoolreplacement" cli option
* Remove (effectively dead) RBF code which would never have been called anyway and some assosiated variables
* since `setConflicts` is always empty, this is dead code
* Since we don't have RBF, don't have to do this check. Also, since `setConflicts` is always empty this is dead code
* removes unneccesary if as it will always be true
* remove unused `set<uint256> setConflicts`
* Removes replacement of conflicting txs, as conflicting txs are never accepted
* removes RBF from `validForFeeEstimation`
* removes (probably) unnecessary lock
* remove replacing part of the AcceptToMemoryPool and AcceptToMemoryPoolWIthTime
* fixes err in ps.cpp, didn't remove arg
* RBF in net_processing.cpp
* remove arg in ps-server.cpp
* removes another arg in PS code
* removes rawtx.c AcceptToMemoryPool arg
* removes arg in txvalidationcache_tests.cpp
* remove extra args
* forgot an arg
* fix typo in 82898b0
* remove unused fEnableReplacement in validation.h
* remove the removal reason REPLACED in txmempool.h
* removed unused variable
* comment typo
* Split keyIDMasternode into keyIDOwner/keyIDOperator/keyIDVoting
keyIDOwner is the key used for things which should stay in control of the
collateral owner, like proposal voting.
keyIDOperator is the key used for operational things, like signing network
messages, signing trigger/watchdog objects and trigger votes.
keyIDVoting is the key used for proposal voting
Legacy masternodes will always have the same key for all 3 to keep
compatibility.
Using different keys is only allowed after spork15 activation.
* Forbid reusing collateral keys for operator/owner keys and vice versa
* Bump SERIALIZATION_VERSION_STRING in CMasternodeMan
* CSporkManager class serialization

Fix was introdeced in:

A fix was later applied to fix a race condition:
https://github.com/dashpay/dash/pull/1178
This has to be reverted to be able to backport multiple changes from Bitcoin.
Later backported PRs from Bitcoin will remove cs_mapRelay and thus also
remove the deadlock that was initially fixed with the above PRs.

* 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

* Allow compilation with `--disable-wallet`
* fix remaining references
* Drop wallet references/include in CActiveMasternode and fix other files affected by this change
* Wrap privatesend-client.h include with ifdef/endif and fix other files affected by this change

This monstrous change eliminates all remaining uses of
g_connman global variable in Dash-specific code.
Unlike previous changes eliminating g_connman use
that were isolated to particular modules, this one covers
multiple modules simultaneously because they are so interdependent
that change in one module was quickly spreading to others.
This is mostly invariant change that was done by
* changing all functions using g_connman to use connman argument,
* changing all functions calling these functions to use connman argument,
* repeating previous step until there's nothing to change.
After multiple iterations, this process converged to final result,
producing code that is mostly equivalent to original one, but passing
CConnman instance through arguments instead of global variable.
The only exception to equivalence of resulting code is that I had to
create overload of CMasternodeMan::CheckAndRemove() method without arguments
that does nothing just for use in CFlatDB<CMasternodeMan>::Dump() and
CFlatDB<CMasternodeMan>::Load() methods.
Normal CMasternodeMan::CheckAndRemove() overload now has argument of
CConnman& type and is used everywhere else.
The normal overload has this code in the beginning:
if(!masternodeSync.IsMasternodeListSynced()) return;
Masternode list is not synced yet when we load "mncache.dat" file,
and we save "mncache.dat" file on shutdown, so I presume that it's OK
to use overload that does nothing in both cases.

* 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.
* net: Split resolving out of CNetAddr
* net: Split resolving out of CService
* net: Split resolving out of CSubNet
* net: move CNetAddr/CService/CSubNet out of netbase
* net: narrow include scope after moving to netaddress
Net functionality is no longer needed for CAddress/CAddrman/etc. now that
CNetAddr/CService/CSubNet are dumb storage classes.
* net: Add direct tests for new CSubNet constructors
* net: Have LookupNumeric return a CService directly
Also fix up a few small issues:
- Lookup with "badip:port" now sets the port to 0
- Don't allow assert to have side-effects
* net: fixup nits
After #8594 the addrFrom sent by a node is not used anymore at all,
so don't bother sending it.
Also mitigates the privacy issue in (#8616). It doesn't completely solve
the issue as GetLocalAddress is also called in AdvertiseLocal, but at
least when advertising addresses it stands out less as *our* address.
We should learn about new peers via address messages.
An inbound peer connecting to us tells us nothing about
its ability to accept incoming connections from us, so
we shouldn't assume that we can connect to it based on
this.
The vast majority of nodes on the network do not accept
incoming connections, adding them will only slow down
the process of making a successful connection in the
future.
Nodes which have configured themselves to not announce would prefer we
not violate their privacy by announcing them in GETADDR responses.
* 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.

* Adjust check in headers timeout logic to align with 144 blocks in Dash
* net: fix typo causing the wrong receive buffer size

These conditions are problematic to check without locking, and we shouldn't be
relying on the refcount to disconnect.
* net: wait until the node is destroyed to delete its recv buffer
when vRecvMsg becomes a private buffer, it won't make sense to allow other
threads to mess with it anymore.
* net: set message deserialization version when it's actually time to deserialize
We'll soon no longer have access to vRecvMsg, and this is more intuitive anyway.
* net: handle message accounting in ReceiveMsgBytes
This allows locking to be pushed down to only where it's needed
Also reuse the current time rather than checking multiple times.
* net: record bytes written before notifying the message processor
* net: Add a simple function for waking the message handler
This may be used publicly in the future
* net: remove useless comments
* net: remove redundant max sendbuffer size check
This is left-over from before there was proper accounting. Hitting 2x the
sendbuffer size should not be possible.
* net: rework the way that the messagehandler sleeps
In order to sleep accurately, the message handler needs to know if _any_ node
has more processing that it should do before the entire thread sleeps.
Rather than returning a value that represents whether ProcessMessages
encountered a message that should trigger a disconnnect, interpret the return
value as whether or not that node has more work to do.
Also, use a global fProcessWake value that can be set by other threads,
which takes precedence (for one cycle) over the messagehandler's decision.
Note that the previous behavior was to only process one message per loop
(except in the case of a bad checksum or invalid header). That was changed in
PR #3180.
The only change here in that regard is that the current node now falls to the
back of the processing queue for the bad checksum/invalid header cases.
* net: add a new message queue for the message processor
This separates the storage of messages from the net and queued messages for
processing, allowing the locks to be split.
* net: add a flag to indicate when a node's process queue is full
Messages are dumped very quickly from the socket handler to the processor, so
it's the depth of the processing queue that's interesting.
The socket handler checks the process queue's size during the brief message
hand-off and pauses if necessary, and the processor possibly unpauses each time
a message is popped off of its queue.
* net: add a flag to indicate when a node's send buffer is full
Similar to the recv flag, but this one indicates whether or not the net's send
buffer is full.
The socket handler checks the send queue when a new message is added and pauses
if necessary, and possibly unpauses after each message is drained from its buffer.
* net: remove cs_vRecvMsg
vRecvMsg is now only touched by the socket handler thread.
The accounting vars (nRecvBytes/nLastRecv/mapRecvBytesPerMsgCmd) are also
only used by the socket handler thread, with the exception of queries from
rpc/gui. These accesses are not threadsafe, but they never were. This needs to
be addressed separately.
Also, update comment describing data flow
* Dont deserialize nVersion into CNode, should fix#9212
* net: deserialize the entire version message locally
This avoids having some vars set if the version negotiation fails.
Also copy it all into CNode at the same site. nVersion and
fSuccessfullyConnected are set last, as they are the gates for the other vars.
Make them atomic for that reason.
* net: don't run callbacks on nodes that haven't completed the version handshake
Since ForEach* are can be used to send messages to all nodes, the caller may
end up sending a message before the version handshake is complete. To limit
this, filter out these nodes. While we're at it, may as well filter out
disconnected nodes as well.
Delete unused methods rather than updating them.
* net: Disallow sending messages until the version handshake is complete
This is a change in behavior, though it's much more sane now than before.
* net: log an error rather than asserting if send version is misused
Also cleaned up the comments and moved from the header to the .cpp so that
logging headers aren't needed from net.h
* Implement conditions for ForEachNode() and ForNode() methods of CConnman.
A change making ForEachNode() and ForNode() methods ignore nodes that
have not completed initial handshake have been backported from Bitcoin.
Unfortunately, some Dash-specific code needs to iterate over all nodes.
This change introduces additional condition argument to these methods.
This argument is a functional object that should return true for nodes
that should be taken into account, not ignored.
Two functional objects are provided in CConnman namespace:
* FullyConnectedOnly returns true for nodes that have handshake completed,
* AllNodes returns true for all nodes.
Overloads for ForEachNode() and ForNode() methods without condition argument
are left for compatibility with non-Dash-specific code.
They use FullyConnectedOnly functional object for condition.

* Iterate over all nodes in Dash-specific code using AllNodes condition.
Use AllNodes functional object as newly introduced condition argument for
ForEachNode() and ForNode() methods of CConnman to iterate over all nodes
where needed in Dash-specific code.

* net: a few small cleanups before replacing boost threads
- Drop the interruption point directly after the pnode allocation. This would
be leaky if hit.
- Rearrange thread creation so that the socket handler comes first
* net: add CThreadInterrupt and InterruptibleSleep
* net: make net interruptible
Also now that net threads are interruptible, switch them to use std
threads/binds/mutexes/condvars.
* net: make net processing interruptible
* net: remove thread_interrupted catch
This is now a std::thread, so there's no hope of catching a boost interruption
point.
* net: make proxy receives interruptible
* net: misc header cleanups
* Remove orphan state wipe from UnloadBlockIndex.
As orphan state is now "network state", like in
d6ea737be1,
UnloadBlockIndex is only used during init if we end up reindexing
to clear our block state so that we can start over. However, at
that time no connections have been brought up as CConnman hasn't
been started yet, so all of the network processing state logic is
empty when its called.
* Move network-msg-processing code out of main to its own file
* Rename the remaining main.{h,cpp} to validation.{h,cpp}
