793290f940a9af18d4f0292a263d976a066dff65 Net: Fixed a race condition when disabling the network. (lmanners)
Pull request description:
This change addresses a race condition where setnetworkactive=false wouldn't always disconnect all peers.
Before this change, the following could happen:
1. Thread A -- Begins connecting to a node.
2. Thread B -- Sets kNetworkActive=false and disconnects connected nodes.
3. Thread A -- Finishes connecting and adds node to list of connected nodes.
The node that was connected from Thread A remains connected and active,
even though kNetworkActive=false.
To fix the race, disconnections when kNetworkActive=false are now handled in the main network loop.

We now have hundreds of MN connections due to the new intra quorum connections,
which means having a limiting semaphore here doesn't make sense anymore. It
actually causes DKG and signing failures as not all necessary connections
can be established.
Masternode connections are still implicitely limited as there is always
only a limited set of LLMQs active.
1cff3d6cb0 Change in transaction pull scheduling to prevent InvBlock-related attacks (Gleb Naumenko)
Pull request description:
This code makes executing two particular (and potentially other) attacks harder.
### InvBlock
This behavior was described well [here](https://www.cs.umd.edu/projects/coinscope/coinscope.pdf) (page 11).
Per current implementation, if node A receives _INV_ (tx) from node B, node A sends _GETDATA_ to B and waits for _TX_ message back.
Node A is likely to receive more _INVs_ (regarding the same tx) from other peers. But node A would not send another _GETDATA_ unless it does not hear _TX_ back from node B for next 2 minutes (to save bandwidth)
Thus, if B is a malicious node, it can prevent node A from getting the transaction (even if all A’s peers have it) for 2 minutes.
This behavior seems to be an inherent limitation of the current P2P relay protocol, and I don’t see how it can be fundamentally changed (I can see workarounds which involve rewriting a lot of P2P code though).
### What does this PR fix?
The attacks I’m looking at involve preventing A from learning the transaction for 2*N minutes. To do that, an attacker has to spin up N nodes and send N _INVs_ simultaneously to node A (then InvBlocks will be queued with an interval of 2 minutes according to current implementation)
More precisely, 2 scenarios I’m looking at are:
1. An attacker censors a particular transaction. By performing InvBlock from different nodes, an attacker can execute a network-wide censorship of a particular transaction (or all transactions). The earlier an attacker founds the transaction he wants to censor, the easier it is to perform an attack. As it was pointed out by @gwillen, this is even more dangerous in the case of lightning, where transactions are known in advance.
2. Topology inference described in papers [1](https://www.cs.umd.edu/projects/coinscope/coinscope.pdf), [2](https://arxiv.org/pdf/1812.00942.pdf) involve network-wide InvBlock. This fix would not mitigate this type of inference, but I believe it will make it more expensive to perform (an attacker would have to create more transactions and perform more rounds to learn the topology, the second paper itself notes that InvBlock isolation is important for the attack).
### How does it work
This PR introduces bias toward outbound connections (they have higher priority when a node chooses from whom it should request a transaction) and randomizes the order.
As per @gmaxwell suggestion, GETDATA requests queue is created after processing all incoming messages from all nodes.
After this fix, if the incoming messages were [I1, I2, I3, O1, O2, O3, O4], the queue for _GETDATA_ may look like [O2, O1, O3, O4, I1, I3, I2, ….].
If {I1, I2, I3} were significantly earlier (but the difference is less than TX_TIMEOUT=60 s) than others, the queue for _GETDATA_ may look like [I2, O2, O1, O3, O4, I1, I3, ….].
### Other comments:
1. This mitigation works better if the connectivity is higher (especially outbound, because it would be less likely that 2 _GETDATAs_ for inbound malicious nodes queued together)

Only sleep 100ms when we previously tried to connect a MN. The back-off
logic in ThreadOpenMasternodeConnections will prevent too many unsuccessful
connects to offline/bad nodes.
Instead of only doing it the first time. This is a preparation for
the new intra-quorum connection system (which connects all members to all
other members)
The way it was implemented caused vPendingMasternodes entries to be popped
but not necessarily connected to when at the same time quorum connections
were pending.

**Note to reviewers:** Please let me know if I've missed any obvious `std::unique_ptr` candidates. Hopefully this PR should cover all the trivial cases.

We could be reading multiple messages from a socket buffer at once _without actually processing them yet_ which means that `fSuccessfullyConnected` might not be switched to `true` at the time we already parsed `VERACK` message and started to parse the next one. This is basically a false positive and we drop a legit node as a result even though the order of messages sent by this node was completely fine. To fix this I partially reverted #2790 (where the issue was initially introduced) and moved the logic for tracking the first message into ProcessMessage instead.

Pull request description:
4440710 broke inserting entries into addrman from dnsseeds which
did not support service bits, as well as static seeds. Static seeds
were already being filtered by UA for 0.13.1+ (ie NODE_WITNESS), so
simply changing the default service bits to include NODE_WITNESS
(and updating docs appropriately) is sufficient. For DNS Seeds, not
supporting NODE_WITNESS is no longer useful, so instead use
non-filtering seeds as oneshot hosts irrespective of named proxy.
I've set my testnet-seed to also support x9, though because it is simply a static host, it may be useful to leave the support off so that it is used as a oneshot to get addresses from a live node instead. I'm fine with either.

* `NULL` → `nullptr` is handled in PR #10483 (scripted)
* `0` → `nullptr` is handled in PR #10645 (manual, this PR)
By using the C++11 keyword `nullptr` we are guaranteed a prvalue of type `std::nullptr_t`.
For a more thorough discussion, see "A name for the null pointer: nullptr" (Sutter &

This avoids sorting before looping through it to figure out what to
request. The assumption that sorting would be cheap when vecAskFor is
already mostly sorted (only unsorted at the end) turned out to be false.
In reality, ~50% of CPU time was consumed by the sort when a lot of traffic
(thousands of TXs) happen.

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.

```
The read of the uninitialized variable `nLocalServices` is triggered by `g_connman->GetLocalServices()` in `getnetworkinfo(const JSONRPCRequest& request)` (`net.cpp:462`):
```c++
UniValue getnetworkinfo(const JSONRPCRequest& request)
{
...
if(g_connman)
obj.push_back(Pair("localservices", strprintf("%016x", g_connman->GetLocalServices())));
...
}
```
The reason for the uninitialized `nLocalServices` is that `CConnman::Start(...)` is not called
by the tests, and hence the initialization normally performed by `CConnman::Start(...)` is
not done.
This commit adds a method `Init(const Options& connOptions)` which is called by both the
constructor and `CConnman::Start(...)`. This method initializes `nLocalServices` and the other
relevant values from the supplied `Options` object.

Readability, SetSocketNonBlocking does what it says on the tin.
Consistency, More consistent with the rest of the API in this unit.
Reusability, SetSocketNonBlocking can also be used by clients that may not want to close the socket on failure.
This also moves the responsibility of closing the socket back to the caller that opened it, which in general should know better how and when to close it.

* 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.

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

* Only relax default port check when AllowMultiplePorts is true

It's not a good idea to try to connect to an old address of a masternode.
This will also skip connection attempts when the masternode is not in the
valid set anymore (banned or collateral spent).
* Pass CNode* to IsMasternodeQuorumNode and let it also check verifiedProRegTxHash
This makes IsMasternodeQuorumNode return true on incoming peer connections
as well.
* Let GetMasternodeQuorumNodes also take verifiedProRegTxHash into account
This makes it return NodeIds for incoming peer connections as well.
* Remove AddParticipatingNode and the need for it
This was needed in the past when we were unable to identify incoming
connections from other quorum members. Now that we have MNAUTH, we can
easily identify all connected members.
* Don't track interestedIn quorums in CSigSharesNodeState anymore
Same as with the previous commit, we're now able to easily identify which
nodes to announce sig shares to.
* Remove unused CConnman::GetMasternodeQuorumAddresses
* Sort evo/* source files in Makefile.am
* Keep track of proRegTxHash in CConnman::masternodeQuorumNodes map
We will later need the proRegTxHash
* 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
* Bump MAX_OUTBOUND_MASTERNODE_CONNECTIONS to 250 on masternodes
Masternodes now need to connect to much more other MNs due to the intra-quorum
communication.
250 is a very conservative value loosely based on the absolute worst-case
number of outgoing connections required, assuming that a MN manages to
become part of all 24 active LLMQs.
* Fix infinite loop in CConnman::Interrupt
* Move out conditional calc into it's own variable

This adds the reading side of a pipe to the read-set when calling select().
Writing to the writing side of the pipe then causes select() to wake up
immediately. Otherwise it would wait for the timeout of 50ms, even if there
is data that could possibly be sent.
This is useful when many messages need are pushed with optimistic send being
disabled. After all messages have been pushed, WakeSelect() can then wakeup
the select() thread and force a re-check for pending data to send.
This is currently only implemented for POSIX compliant systems as we assume
that heavy-load daemons (like masternodes) are usually run on Linux.
Profiling has shown that optimistic send causes measurable slowdowns when
many messages are pushed, even if the sockets are non-blocking. Better to
allow disabling of optimistic sending in such cases and let the network
thread do the actual socket calls.
* 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
* check request is not empty to use it for filtering
* Filter vote INVs by tx hash

* Apply suggestions from code review

* 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
* Remove testnet seeds from devnet
* Lift multiple ports restriction on devnet when considering new nodes
Allow to connect to multiple nodes behind the same IP
* Don't skip addresses with non-default port if it matches -port
If the user specified -port, he very likely intends to connect to nodes
with the same port.
* Don't pass false to CAddrMan constructor as it is already the default
* Make if statements easier to read
* 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.
* Drop nBudgetProposalEstablishingTime
* Refactor: replace `== COutPoint()` with `.IsNull()`
* Refactor: add `operator bool()` to CMasternodePing
* Refactor: actually use `operator bool()` for CPendingDsaRequest
* Refactor: fixing code style in TrafficGraphData
* Fix some comments and whitespaces
* Drop CGovernanceVote::GetTypeHash()
* Drop legacy X11 code
No longer used... if it ever was used at all.
* Move `<boost/foreach.hpp>` out of coins.h
* Simplify CMasternodeBlockPayees::GetRequiredPaymentsString()
Also less of boost::lexical_cast
* Drop CTxDSIn::nSentTimes
* Fix few warnings
* fix warning (timer)
* fix nit
* Remove unnecessary LOCK in ConnectNode
FindNode already does the necessary lock
* Remove unnecessary semicolon
* Remove critical section and assert for ref counts in CNode
nRefCount is an atomic now and thus doesn't need locking anymore.
* Drop BOOST_FOREACH in Dash-specific code (only), no changes in behavior
* Use references in loops (use const references where applicable) in Dash-specific code (only)
And adjust related code to make it compilable.
* Loop through nodes via connman.ForEachNode in dsq Relay instead of creating a copy
* Do not send dash-specific requests to masternodes before we are fully connected
Open all masternode connections via CConnman::ThreadOpenMasternodeConnections only. Queue requests and process them after some timeout.
* drop excessive `mnodeman.`
* switch from queues to maps of pending requests
* adjust few strings, add TODO for POOL_STATE_CONNECTING
* fix
* there can be only one pending dsa request per ps client

ConnectNode is meant to be private and should not be leaked outside of

behaviour. We use OpenNetworkConnectio/OpenMasternodeConnection from now on
and use appropriate ForNode calls to access the CNode* instance.
This commit also changes the behaviour for already connected nodes which
are afterwards requested for a masternode connection. We don't set
fMasternode=true anymore on such nodes, which means it won't be auto
disconnected anymore from ProcessMasternodeConnections.

* 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

* net: Add direct tests for new CSubNet constructors

Note: Some seeds aren't actually returning an IP for their name entries, so
they're being added to addrman with a source of [::].
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.
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.
* 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.

* 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
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
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.

* 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
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.
* 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.
* 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.
* 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
* 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.

* Few networking fixes:
- skip "masternode"/inbound connections for sync related processes
- do not sync gov data to other nodes until fully synced ourselves
- do not accept incoming connections until fully synced
* inbound connections could be harmful only if our node is a masternode
* same for CGovernanceManager::Sync
* Multi-quorum InstantSend, complete refactoring
+ cleanup for IS and partial protobump
* more changes:
- allow InstantSend tx to have 10 inputs max
- store many unique tx hashes in mapVotedOutpoints
- more checks in AcceptToMemoryPoolWorker (moved from ProcessMessage + CTxLockRequest(tx).IsValid() )
* More changes:
- let multiple lock candidates compete for votes
- fail to vote on the same outpoint twice early
* More changes:
- notify CInstantSend on UpdatedBlockTip -> remove cs_main from CheckAndRemove()
- notify CInstantSend on SyncTransaction -> count expiration block starting from the block corresponding tx was confirmed instead of the block lock candidate/vote was created
- fixed few locks
* add comments about nConfirmedHeight
* Fix "Block vs Lock" edge case
* Fix "Block vs Lock" edge case, p2
* Fix issues:
- fix logic for locking inputs and notifying - see UpdateLockedTransaction, TryToFinalizeLockCandidate
- add missing hash inserting in ProcessTxLockVote
- add nMaxBlocks param to ResolveConflicts to limit max depth allowed to disconnect blocks recursively
- fix false positive mempool conflict
- add missing mutex locks
- fix fRequireUnspent logic in CTxLockRequest::IsValid
- some were not used, some were included twice, some were in the wrong place, some were missing (but it compiled because some were in the wrong place)
- organized a bit better, grouped dash specific includes in original bitcoin files, should save some time solving conflicts when/if merging patches later
