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.
- add `MASTERNODE_SYNC_WAITING` sync state/asset and initial timeout
- wait for block headers to be downloaded (new signal `AcceptedBlockHeader`)
- wait for blocks to reach best headers tip before switching to masternode list sync (new signal `NotifyHeaderTip`)
- switched sync from `UpdatedBlockTip` to a combination of `AcceptedBlockHeader` and `NotifyHeaderTip`
- all blockchain-related bumps should take place only while we are still syncing blockchain, should be no such bumps after that

Note: Some seeds aren't actually returning an IP for their name entries, so

This commit shouldn't change that behavior, for better or worse.
* net: resolve outside of storage structures
Rather than allowing CNetAddr/CService/CSubNet to launch DNS queries, require
that addresses are already resolved.
This greatly simplifies async resolve logic, and makes it harder to
accidentally leak DNS queries.
* net: disable resolving from storage structures
CNetAddr/CService/CSubnet can no longer resolve DNS.
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.
The use of mocktime in test logic means that comparisons between
GetTime() and GetTimeMicros()/1000000 are unreliable since the former
can use mocktime values while the latter always gets the system clock;
this changes the networking code's inactivity checks to consistently
use the system clock for inactivity comparisons.
Also remove some hacks from setmocktime() that are no longer needed,
now that we're using the system clock for nLastSend and nLastRecv.
* fixed an issue with MasternodeRateCheck always returns true
* additioanal fixes and refactoring (rebase)
* slightly improved CRateBuffer synchronization for newly started nodes
* 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
* net: fix typo causing the wrong receive buffer size
Surprisingly this hasn't been causing me any issues while testing, probably
because it requires lots of large blocks to be flying around.
Send/Recv corks need tests!
* net: make vRecvMsg a list so that we can use splice()
* net: make GetReceiveFloodSize public
This will be needed so that the message processor can cork incoming messages
* net: only disconnect if fDisconnect has been set
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.

* Remove un-needed #includes (what is the policy?)
Data was duplicated in masternode_info_t and CMasternode classes:
* CMasternode is changed to inherit from masternode_info_t
so the data members are inherited rather than repeated
(also inherits unrepeated nTimeLastPing and fInfoValid members;
this slight intrusiveness made up for in simplicity).
* Use in-class member initializers (C++11) for defaults,
so only non-default initializers are required in the lists.
Allows to shorten repetitous constructor initializer lists.
This makes checking for uninitialized data simpler.
* Default constructors are defined as "= default;" if possible.
* masternode_info_t is changed to behave like an aggregate
(but requires over-complicated constructors until c++14).
There are pros and cons here - aggregate initialization
is convenient but implicit).

using the copy-in,swap-and-return idiom:

- IsBlockchainSynced(): drop CheckNodeHeight() and all complicated code, use fInitialDownload in UpdatedBlockTip() to switch initial states
- ProcessTick(): detect sleep mode like it was in IsBlockchainSynced(), not by number of masternodes
* Changes for sync in governance:
- do not keep sync alive on ConfirmInventoryRequest()
- skip some governance actions until we are synced to some level
* do not run CMasternodeMan::UpdateLastPaid() until winners list is synced
* start syncing mn list on the same node right after requesting sporks
* replace nTimeLast<Asset> with the unified nTimeLastBumped, bump on UpdatedBlockTip
* fix comments and LogPrintf-s
* remove excessive MASTERNODE_SYNC_IBD
* a bit more descriptive BumpAssetLastTime in few cases
* 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}
* net: Consistent checksum handling
In principle, the checksums of P2P packets are simply 4-byte blobs which
are the first four bytes of SHA256(SHA256(payload)).
Currently they are handled as little-endian 32-bit integers half of the
time, as blobs the other half, sometimes copying the one to the other,
resulting in somewhat confused code.
This PR changes the handling to be consistent both at packet creation
and receiving, making it (I think) easier to understand.
* net: Hardcode protocol sizes and use fixed-size types
The P2P network uses a fixed protocol, these sizes shouldn't change
based on what happens to be the architecture.
* Expose AcceptBlockHeader through main.h
* Split ::HEADERS processing into two separate cs_main locks
This will allow NotifyHeaderTip to be called from an
AcceptBlockHeader wrapper function without holding cs_main.
* Use exposed ProcessNewBlockHeaders from ProcessMessages
* Remove pfrom parameter from ProcessNewBlock
This further decouples ProcessNewBlock from networking/peer logic.
* Replace CValidationState param in ProcessNewBlock with BlockChecked
* Move MarkBlockAsReceived out of ProcessNewMessage
* Remove network state wipe from UnloadBlockIndex.
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.
Additionally, the initialization of the recentRejects set is moved
to InitPeerLogic.
* Move all calls to CheckBlockIndex out of net-processing logic
This will result in many more calls to CheckBlockIndex when
connecting a list of headers (eg in ::HEADERS messages processing)
but its only enabled in debug mode, and that should mostly just be
during IBD, so it should be OK.
* Move FlushStateToDisk call out of ProcessMessages::TX into ATMP
* Move nTimeBestReceived updating into net processing code
* Make validationinterface.UpdatedBlockTip more verbose
In anticipation of making all the callbacks out of block processing
flow through it. Note that vHashes will always have something in it
since pindexFork != pindexNewTip.
* Remove duplicate nBlocksEstimate cmp (we already checked IsIBD())
* Remove CConnman parameter from ProcessNewBlock/ActivateBestChain
* Remove SyncWithWallets wrapper function
* Move net-processing logic definitions together in main.h
* Use CValidationInterface from chain logic to notify peer logic
This adds a new CValidationInterface subclass, defined in main.h,
to receive notifications of UpdatedBlockTip and use that to push
blocks to peers, instead of doing it directly from
ActivateBestChain.
* Always call UpdatedBlockTip, even if blocks were only disconnected
* Use BlockChecked signal to send reject messages from mapBlockSource
In the case of (for example) an already-running bitcoind, the shutdown sequence
begins before CConnman has been created, leading to a null-pointer dereference
when g_connman->Stop() is called.
Instead, Just let the CConnman dtor take care of stopping.
* serialization: teach serializers variadics
Also add a variadic CDataStream ctor for ease-of-use.
* connman is in charge of pushing messages
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: switch all callers to connman for pushing messages
Drop all of the old stuff.
* drop the optimistic write counter hack
This is now handled properly in realtime.
* net: remove now-unused ssSend and Fuzz
* net: construct CNodeStates in place
* net: handle version push in InitializeNode
* net: Add fRelayTxes flag
Add a fRelayTxes to keep track of the relay transaction flag
we send to other peers.
* rpc: Add `relaytxes` flag to `getnetworkinfo`
Re-work of PR #7841 by dragongem45.
Closes#7771.
* net: move CBanDB and CAddrDB out of net.h/cpp
This will eventually solve a circular dependency
* net: Create CConnman to encapsulate p2p connections
* net: Move socket binding into CConnman
* net: move OpenNetworkConnection into CConnman
* net: move ban and addrman functions into CConnman
* net: Add oneshot functions to CConnman
* net: move added node functions to CConnman
* net: Add most functions needed for vNodes to CConnman
* net: handle nodesignals in CConnman
* net: Pass CConnection to wallet rather than using the global
* net: Add rpc error for missing/disabled p2p functionality
* net: Pass CConnman around as needed
* gui: add NodeID to the peer table
* net: create generic functor accessors and move vNodes to CConnman
* net: move whitelist functions into CConnman
* net: move nLastNodeId to CConnman
* net: move nLocalHostNonce to CConnman
This behavior seems to have been quite racy and broken.
Move nLocalHostNonce into CNode, and check received nonces against all
non-fully-connected nodes. If there's a match, assume we've connected
to ourself.
* net: move messageHandlerCondition to CConnman
* net: move send/recv statistics to CConnman
* net: move SendBufferSize/ReceiveFloodSize to CConnman
* net: move nLocalServices/nRelevantServices to CConnman
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).
* net: move semOutbound and semMasternodeOutbound to CConnman
* net: SocketSendData returns written size
* net: move max/max-outbound to CConnman
* net: Pass best block known height into CConnman
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: pass CClientUIInterface into CConnman
* net: Drop StartNode/StopNode and use CConnman directly
* net: Introduce CConnection::Options to avoid passing so many params
* net: add nSendBufferMaxSize/nReceiveFloodSize to CConnection::Options
* net: move vNodesDisconnected into CConnman
* Made the ForEachNode* functions in src/net.cpp more pragmatic and self documenting
* Convert ForEachNode* functions to take a templated function argument rather than a std::function to eliminate std::function overhead
* net: move MAX_FEELER_CONNECTIONS into connman
* lock cs_main for chainActive
ActivateBestChain uses chainActive after releasing the lock; reorder operations
to move all access to synchronized object into existing LOCK(cs_main) block.
* lock cs_main for State/Misbehaving
ProcessMessage calls State(...) and Misbehaving(...) without holding the
required lock; add LOCK(cs_main) blocks.
Tests if addresses are online or offline by briefly connecting to them. These short lived connections are referred to as feeler connections. Feeler connections are designed to increase the number of fresh online addresses in tried by selecting and connecting to addresses in new. One feeler connection is attempted on average once every two minutes.

The partition checker was producing huge number of false-positives
and was disabled in 0.12.1 on the understanding it would either be
fixed in 0.13 or removed entirely from master if not.
*** Dash specific note: ***
This check was disabled in Dash already.
* Rework addnode behaviour
* Use CNode::addeName to track whether a connection to a name is already open
* A new connection to a previously-connected by-name addednode is only opened when
the previous one closes (even if the name starts resolving to something else)
* At most one connection is opened per addednode (even if the name resolves to multiple)
* Unify the code between ThreadOpenAddedNodeConnections and getaddednodeinfo
* Information about open connections is always returned, and the dns argument becomes a dummy
* An IP address and inbound/outbound is only reported for the (at most 1) open connection
* Prevent duplicate connections where one is by name and another by ip
* Randomize name lookup result in ConnectSocketByName
* fix vulnerability with mapMasternodeOrphanObjects
The vulnerability is that a malicious node can send a lot of NetMsgType::MNGOVERNANCEOBJECT messages which refer to many arbitrary MN's. In this case, mapMasternodeOrphanObjects will grow unrestrictedly.
* MN collateral moved to governance-object.cpp; ban score applied to misbehaving nodes
* recursive locks removed
* check for the mn collateral code segregated to a separate function
* CheckCollateral implementation moved to cpp
This reverts commit 1f828f45ec.
The commit being reverted changed FindNode(const CService& addr)
to make no difference between nodes with the same IP address,
but different ports, but only for regtest network.
As functional tests run several nodes on different ports or the same
IP address (127.0.0.1), this eventually started breaking functional tests.
The only use for regtest network I know is for functional tests,
so it's time to revert that commit.
* fix issues with mapSeenGovernanceObjects
Removed seen-governance-objects optimization except for deleted objects. Otherwise some nodes can permanently lost proposals if they received them too early.
Beside of that there is a vulnerability with seen-governance-objects mechanism if malicious node send us a lot of invalid governance objects.
* mapSeenGovernanceObjects renamed to mapErasedGovernanceObjects
* current fixes
* use int64_t for expiration timestamp
* Add recently accepted blocks and txn to AttemptToEvictConnection.
This protects any not-already-protected peers who were the most
recent four to relay transactions and most recent four to send
blocks to us.
* Allow disconnecting a netgroup with only one member in eviction.
With the latest additions there are enough protective measures that
we can take the training wheels off.
* net: don't import std namespace
This file is about to be broken up into chunks and moved around. Drop the
namespace now rather than requiring other files to use it.
* net: remove unused set
* net: use the exposed GetNodeSignals() rather than g_signals directly
* net: make Ban/Unban/ClearBan functionality consistent
- Ban/Unban/ClearBan call uiInterface.BannedListChanged() as necessary
- Ban/Unban/ClearBan sync to disk if the operation is user-invoked
- Mark node for disconnection automatically when banning
- Lock cs_vNodes while setting disconnected
- Don't spin in a tight loop while setting disconnected
* net: No need to export DumpBanlist
DumpBanList currently does this:
- with lock: take a copy of the banmap
- perform I/O (write out the banmap)
- with lock: mark the banmap non-dirty
If a new ban is added during the I/O operation, it may never be persisted to
disk.
Reorder operations so that the data to be persisted cannot be older than the
time at which the banmap was marked non-dirty.
* Make ProcessNewBlock dbp const and update comment
* Switch reindexing to AcceptBlock in-loop and ActivateBestChain afterwards
* Optimize ActivateBestChain for long chains
* Add -reindex-chainstate that does not rebuild block index
* Report reindexing progress in GUI
* Only store and connect to NODE_NETWORK nodes
* Keep addrman's nService bits consistent with outbound observations
* Verify that outbound connections have expected services
* Don't require services in -addnode
* Introduce enum ServiceFlags for service flags
* Introduce REQUIRED_SERVICES constant
* CAddrDB modified so that when de-serialization code throws an exception Addrman is reset to a clean state
* CAddrDB modified to make unit tests possible
* Regression test created to ensure bug is fixed
* StartNode modifed to clear adrman if CAddrDB::Read returns an error code.
* process governance objects in CheckMasternodeOrphanObjects as usual
* code refactoring: SetRateChecksHelper class added
* fixed race condition issues with propagation of governance objects
* change GetCollateralConfirmations signature
* code refactoring
* reduced minimum number of collateral confirmations required for relaying proposals
* bug fixes and improvements
* banlist: update set dirty to be more fine grained
- move the SetBannedSetDirty(false) call from DumpData() into DumpBanlist()
- ensure we only set false, if the write succeeded
* banlist: better handling of banlist in StartNode()
- only start working on/with banlist data, if reading in the banlist from
disk didn't fail
- as CNode::setBannedIsDirty is false (default) when reading fails, we
don't need to explicitly set it to false to prevent writing
banlist.dat in that case either
* banlist: add more banlist infos to log / add GUI signal
- to match the peers.dat handling also supply a debug.log entry for how
many entries were loaded from banlist.dat and how long it took
- add a GUI init message for loading the banlist (same as with peers.dat)
- move the same message for peers.dat upwards in the code, to be able to
reuse the timing variable nStart and also just log, if our read from
peers.dat didn't fail
* banlist (bugfix): allow CNode::SweepBanned() to run on interval
- allows CNode::SweepBanned() to run, even if !CNode::BannedSetIsDirty(),
because if nBanUntil is over we want the ban to be disabled for these
nodes
* Add hassentinelping to governanceinfo

* Bugfix: Always include univalue in DIST_SUBDIRS
* LDADD dependency order shuffling
* build-unix: Update UniValue build conditions
ProcessNewBlock would return failure early if CheckBlock failed, before
calling AcceptBlock. AcceptBlock also calls CheckBlock, and upon failure
would update mapBlockIndex to indicate that a block was failed. By returning
early in ProcessNewBlock, we were not marking blocks that fail a check in
CheckBlock as permanently failed, and thus would continue to re-request and
reprocess them.
Adds several unittests for CAddrMan and CAddrInfo.
Increases the accuracy of addrman tests.
Removes non-determinism in tests by overriding the random number generator.
Extracts testing code from addrman class to test class.
* log bytes recv/sent per command
* net: Account for `sendheaders` `verack` messages
Looks like these were forgotten in #6589.
* Backport remaining part of Bitcoin PR bitcoin/bitcoin#7181.
Most of this PR is already merged, but a small part remaining
that makes per-command byte counts in CNode working.

Fixes: #1345
The actual problem is that GetDataDir has the side effect of creating the
datadir, even if it is not known yet where it really is. This is only
known after reading the config file or when explicitly specified in the
cmd line.
Thus, if GetDataDir gets called before the datadir value from the config
is read, it tries to create it at the default location.
