Merge #19109: Only allow getdata of recently announced invs

a9bc5638031a29abaa40284273a3507b345c31e9 Swap relay pool and mempool lookup (Pieter Wuille)

Pull request description:

  This implements the follow-up suggested here: https://github.com/bitcoin/bitcoin/pull/18861#issuecomment-627630111 . Instead of checking `setInventoryTxToSend`, maintain an explicit bloom filter with the 3500 most recently announced invs, and permit fetching any of these as long as they're in the relay pool or the mempool. In addition, permit relay from the mempool after just 2 minutes instead of 15.

  This:

  * Fixes the brief opportunity an attacker has to request unannounced invs just after the connection is established (pointed out by naumenkogs, see https://github.com/bitcoin/bitcoin/pull/18861#issuecomment-627627010).
  * Guarantees that locally resubmitted invs after `filterInventoryKnown` rolls over can still be requested (pointed out by luke-jr, see https://github.com/bitcoin/bitcoin/pull/18861#discussion_r419695831).

  It adds 37 KiB of filter per peer.

  This is also a step towards dropping the relay pool entirely and always relaying from the mempool directly (see #17303), but that is still blocked by dealing properly with NOTFOUNDs (see #18238).

Merge #20027: Use mockable time everywhere in net_processing
b6834e312a6a7bb395ec7266bc9469384639df96 Avoid 'timing mishap' warnings when mocking (Pieter Wuille)
ec3916f40a3fc644ecbbaaddef6258937c7fcfbc Use mockable time everywhere in net_processing (Pieter Wuille)

Pull request description:

  The fact that net_processing uses a mix of mockable tand non-mockable time functions made it hard to write functional tests for #19988.

  I'm opening this as a separate PR as I believe it's independently useful. In some ways this doesn't go quite as far as it could, as there are now several data structures that could be converted to `std::chrono` types as well now. I haven't done that here, but I'm happy to reconsider that.

e9a6d8b13b0558b17cdafbd32fd2663b4138ff11 p2p: Unify Send and Receive protocol versions (Hennadii Stepanov)

Pull request description:

  On master (6fef85bfa3cd7f76e83b8b57f9e4acd63eb664ec) `CNode` has two members to keep protocol version:
  - `nRecvVersion` for received messages
  - `nSendVersion` for messages to send

  After exchanging with `VERSION` and `VERACK` messages via protocol version `INIT_PROTO_VERSION`, both nodes set `nRecvVersion` _and_ `nSendVersion` to _the same_ value which is the greatest common protocol version.

  This PR:
  - replaces two `CNode` members, `nRecvVersion` `nSendVersion`, with `m_greatest_common_version`
  - removes duplicated getter and setter

  There is no change in behavior on the P2P network.

Pull request description:

  Addresses some outstanding review comments from #18044

  - reverts unbroadcast txids to a set instead of a map (simpler, communicates intent better, takes less space, no efficiency advantages of map)
  - adds safety around two touchpoints (check for nullptr before dereferencing pointer, remove an inaccurate std::move operator)
  - removes some dead code

Pull request description:

  Although we currently don't do this, it should be possible to create a
  CConnman or PeerLogicValidation without a Banman instance. Therefore
  always check that banman exists before dereferencing the pointer.

  Also add comments to the m_banman members of CConnman and
  PeerLogicValidation to document that these may be nullptr.

Pull request description:

  This is based on https://github.com/bitcoin/bitcoin/pull/18044#discussion_r450687076.

  A new type `GenTxid` is added to protocol.h, which represents a tagged txid-or-wtxid. The tx request logic is updated to use these instead of uint256s, permitting per-announcement distinguishing of txid/wtxid (instead of assuming that everything we want to request from a wtxid peer is wtx). Then the restriction of orphan-parent requesting to non-wtxid peers is lifted.

  Also document BIP339 in doc/bips.md.

Merge bitcoin#18044: Use wtxid for transaction relay
This backport is marked as full, not partial, but it has only refactorings
and non-witness related changes.

Included commits are:
 - test: Update test framework p2p protocol version to 70016
 - Rename AddInventoryKnown() to AddKnownTx()
 - Add support for tx-relay via wtxid

    This adds a field to CNodeState that tracks whether to relay transactions with
    that peer via wtxid, instead of txid. As of this commit the field will always
    be false, but in a later commit we will add a way to negotiate turning this on
    via p2p messages exchanged with the peer.

 - Just pass a hash to AddInventoryKnown

    Since it's only used for transactions, there's no need to pass in an inv type.

 - Add wtxid to mempool unbroadcast tracking

Merge #19620: Add txids with non-standard inputs to reject filter
9f88ded82b2898ca63d44c08072f1ba52f0e18d7 test addition of unknown segwit spends to txid reject filter (Gregory Sanders)
7989901c7eb62ca28b3d1e5d5831041a7267e495 Add txids with non-standard inputs to reject filter (Suhas Daftuar)

Pull request description:

  Our policy checks for non-standard inputs depend only on the non-witness
  portion of a transaction: we look up the scriptPubKey of the input being
  spent from our UTXO set (which is covered by the input txid), and the p2sh
  checks only rely on the scriptSig portion of the input.

  Consequently it's safe to add txids of transactions that fail these checks to
  the reject filter, as the witness is irrelevant to the failure. This is helpful
  for any situation where we might request the transaction again via txid (either
  from txid-relay peers, or if we might fetch the transaction via txid due to
  parent-fetching of orphans).

  Further, in preparation for future witness versions being deployed on the
  network, ensure that WITNESS_UNKNOWN transactions are rejected in
  AreInputsStandard(), so that transactions spending v1 (or greater) witness
  outputs will fall into this category of having their txid added to the reject
  filter.

  Following the merge of wtxid relay in #18044, this is the first of three refactoring PRs (this one, #19610, and #19611) with no change in behavior, tightly scoped to ease review, to simplify the net processing code and improve encapsulation:

  - add `CInv` transaction message helper methods, defined in the class

  - use the new helpers in `net_processing.cpp` to simplify the code and improve encapsulation

  Test coverage is provided by the functional p2p tests, notably (from seeing which tests failed when breaking things to test coverage) `p2p_segwit`, `p2p_tx_download`, `p2p_feefilter`, and `p2p_permissions`.

refactor: split llmq/utils to Quorum Calculation and llmq/options (#5790)
## Issue being fixed or feature implemented
`llmq/utils` has simple util code that used all over code base and also
have too heavy code for calculation quorums such as:
`GetAllQuorumMembers`, `EnsureQuorumConnections` and other.

These helpers for calculation quorums are used only by
evo/deterministicmns, evo/simplifiedmns and llmq/* modules, but
llmq/utils is included in many other modules for various trivial
helpers.



## What was done?
Prior work:
 - https://github.com/dashpay/dash/pull/5753
 - #5486
 See also #4798

This PR remove all non-quorum calculation code from llmq/utils.
Eventually it happens that easier to take everything out rather than
move Quorum Calculation to new place atm:
- new module llmq/options have a code related to various params, command
line options, spork-related etc
- llmq/utils is not included in various files which do not use any
llmq/utils code
 - helper `BuildCommitmentHash` goes to llmq/commitment
 - helper `BuildSignHash` goes to llmq/signing
- helper `GetLLMQParam` inlined since it's trivial (it has not been
trivial when introduced ages ago)
- removed dependency of `IsQuorumEnabled` on CQuorumManager which means
`quorumManager` deglobalization is done for 90%


## How Has This Been Tested?
 - Run unit functional tests
- updated circular dependencies
`test/lint/lint-circular-dependencies.sh`
- check that llmq/utils is not included without needs to calculate
Quorums Members

1c6b787e0319c44f0e0bede3f4a77ac7c2089db2 [netprocessing] disconnect node that sends filterclear (gzhao408)

Pull request description:

  Nodes that don't have bloomfilters turned on (i.e. no `NODE_BLOOM` service) should disconnect peers that send them `filterclear` P2P messages.

  Non-bloomfilter nodes already disconnect peers for [`filteradd` and `filterload`](19e919217e/src/net_processing.cpp (L2218)), but #8709 removed `filterclear` so it could be used to reset tx relay. This isn't needed now because using `feefilter` message is much better for this purpose (See #19204).

  Also refactors existing disconnect logic for `filteradd` and `filterload` into respective message handlers and removes banning for them.

Pull request description:

  After #19316, we can more directly expose information about the connection type on the `getpeerinfo` RPC. Doing so also makes the existing addnode field redundant, so this PR begins the process of deprecating this field.

  This PR also includes one commit that improves a log message, as both use a shared function to return the connection type as a string.

Pull request description:

  **This is part 1 of #19315, which enables the ability to test `outbound` and `block-relay-only` connections from the functional tests.** Please see that PR for more information of overall functionality.

  **This PR simplifies how we manage different connection types.** It introduces an enum with the various types of connections so we can explicitly define the connection type. The existing system relies on a series of independent flags, then has asserts scattered around to ensure that conflicting flags are not enabled at the same time. I find this approach to be both brittle and confusing. While making these changes, I found a small bug due to the silent assumptions.

  This PR also proposes a rename from `OneShot` to `AddrFetch`. I find the name `OneShot` to be very confusing, especially when we also have `onetry` manual connections. Everyone I've talked to offline has agreed that the name is confusing, so I propose a potential alternative. I think this is a good opportunity for a rename since I'm creating an enum to explicitly define the connection types.
  (some context for the unfamiliar: `oneshot` or `addrfetch` connections are short-lived connections created on startup. They connect to the seed peers, send a `getaddr` to solicit addresses, then close the connection.)

  Overview of this PR:
  * rename `oneshot` to `addrfetch`
  * introduce `ConnectionType` enum
  * one by one, add different connection types to the enum
  * expose the `conn_type` on CNode, and use this to reduce reliance on flags (& asserts)
  * fix the bug in counting different type of connections
  * some additional cleanup to simplify logic and make expectations explicit/inclusive rather than implicit/exclusive.

Pull request description:

  This PR intends to improve transaction-origin privacy.

  In general, we should try to not leak information about what transactions we have (recently) learned about before deciding to announce them to our peers. There is a controlled transaction dissemination process that reveals our transactions to peers that has various safeguards for privacy (it's rate-limited, delayed & batched, deterministically sorted, ...), and ideally there is no way to test which transactions we have before that controlled process reveals them. The handling of the `mempool` BIP35 message has protections in this regard as well, as it would be an obvious way to bypass these protections (handled asynchronously after a delay, also deterministically sorted).

  However, currently, if we receive a GETDATA for a transaction that we have not yet announced to the requester, we will still respond to it if it was announced to *some* other peer already (because it needs to be in `mapRelay`, which only happens on the first announcement). This is a slight privacy leak.

  Thankfully, this seems easy to solve: `setInventontoryTxToSend` keeps track of the txids we have yet to announce to a peer - which almost(*) exactly corresponds to the transactions we know of that we haven't revealed to that peer. By checking whether a txid is in that set before responding to a GETDATA, we can filter these out.

  (*) Locally resubmitted or rebroadcasted transactions may end up in setInventoryTxToSend while the peer already knows we have them, which could result in us incorrectly claiming we don't have such transactions if coincidentally requested right after we schedule reannouncing them, but before they're actually INVed. This is made even harder by the fact that filterInventoryKnown will generally keep known reannouncements out of setInventoryTxToSend unless it overflows (which needs 50000 INVs in either direction before it happens).

  The condition for responding now becomes:

  ```
    (not in setInventoryTxToSend) AND
    (
      (in relay map) OR
      (
        (in mempool) AND
        (old enough that it could have expired from relay map) AND
        (older than our last getmempool response)
      )
    )
  ```

746736639e6d05acdb85c866d4c605c947d4c500 [net processing] Only send a getheaders for one block in an INV (John Newbery)

Pull request description:

  Headers-first is the primary method of announcement on the network. If a node fell back sending blocks by inv, it's probably for a re-org. The final block hash provided should be the highest, so send a getheaders and then fetch the blocks we need to catch up.

  Sending many GETHEADERS messages to the peer would cause them to send a large number of potentially large HEADERS messages with redundant data, which is a waste of bandwidth.

refactor: deprecate non-deterministic IS support (#5553)
## Issue being fixed or feature implemented
Non-deterministic IS locks aren't used anymore since v18 dip24.
We should drop that support to make code simpler.

## What was done?
Dropped non-deterministic IS code, `evo_instantsend_tests` and
`feature_llmq_is_migration.py` (don't need it anymore), adjusted func
tests.

## How Has This Been Tested?
all tests, synced Testnet

refactor: decouple db hooks from CFlatDB-based C*Manager objects, migrate to *Store structs (#5555)
## Motivation

As highlighted in https://github.com/dashpay/dash-issues/issues/52,
decoupling of `CFlatDB`-interacting components from managers of objects
like `CGovernanceManager` and `CSporkManager` is a key task for
achieving deglobalization of Dash-specific components.

The design of `CFlatDB` as a flat database agent relies on hooking into
the object's state its meant to load and store, using its
(de)serialization routines and other miscellaneous functions (notably,
without defining an interface) to achieve those ends. This approach was
taken predominantly for components that want a single-file cache.

Because of the method it uses to hook into the object (templates and the
use of temporary objects), it explicitly prevented passing arguments
into the object constructor, an explicit requirement for storing
references to other components during construction. This, in turn,
created an explicit dependency on those same components being available
in the global context, which would block the backport of bitcoin#21866,
a requirement for future backports meant to achieve parity in
`assumeutxo` support.

The design of these objects made no separation between persistent (i.e.
cached) and ephemeral (i.e. generated/fetched during initialization or
state transitions) data and the design of `CFlatDB` attempts to "clean"
the database by breaching this separation and attempting to access this
ephemeral data.

This might be acceptable if it is contained within the manager itself,
like `CSporkManager`'s `CheckAndRemove()` but is utterly unacceptable
when it relies on other managers (that, as a reminder, are only
accessible through the global state because of restrictions caused by
existing design), like `CGovernanceManager`'s `UpdateCachesAndClean()`.

This pull request aims to separate the `CFlatDB`-interacting portions of
these managers into a struct, with `CFlatDB` interacting only with this
struct, while the manager inherits the struct and manages
load/store/update of the database through the `CFlatDB` instance
initialized within its scope, though the instance only has knowledge of
what is exposed through the limited parent struct.

## Additional information

* As regards to existing behaviour, `CFlatDB` is written entirely as a
header as it relies on templates to specialize itself for the object it
hooks into. Attempting to split the logic and function definitions into
separate files will require you to explicitly define template
specializations, which is tedious.

* `m_db` is defined as a pointer as you cannot instantiate a
forward-declared template (see [this Stack Overflow
answer](https://stackoverflow.com/a/12797282) for more information),
which is done when defined as a member in the object scope.

* The conditional cache flush predicating on RPC _not_ being in the
warm-up state has been replaced with unconditional flushing of the
database on object destruction (@UdjinM6, is this acceptable?)

## TODOs

This is a list of things that aren't within the scope of this pull
request but should be addressed in subsequent pull requests

* [ ] Definition of an interface that `CFlatDB` stores are expected to
implement
* [ ] Lock annotations for all potential uses of members protected by
the `cs` mutex in each manager object and store
* [ ] Additional comments documenting what each function and member does
* [ ] Deglobalization of affected managers

refactor: subsume CoinJoin objects under CJContext, deglobalize coinJoin{ClientQueueManager,Server} (#5337)
## Motivation

CoinJoin's subsystems are initialized by variables and managers that
occupy the global context. The _extent_ to which these subsystems
entrench themselves into the codebase is difficult to assess and moving
them out of the global context forces us to enumerate the subsystems in
the codebase that rely on CoinJoin logic and enumerate the order in
which components are initialized and destroyed.

Keeping this in mind, the scope of this pull request aims to:

* Reduce the amount of CoinJoin-specific entities present in the global
scope
* Make the remaining usage of these entities in the global scope
explicit and easily searchable

## Additional Information

* The initialization of `CCoinJoinClientQueueManager` is dependent on
blocks-only mode being disabled (which can be alternatively interpreted
as enabling the relay of transactions). The same applies to
`CBlockPolicyEstimator`, which `CCoinJoinClientQueueManager` depends.

Therefore, `CCoinJoinClientQueueManager` is only initialized if
transaction relaying is enabled and so is its scheduled maintenance
task. This can be found by looking at `init.cpp`
[here](93f8df1c31/src/init.cpp (L1681-L1683)),
[here](93f8df1c31/src/init.cpp (L2253-L2255))
and
[here](93f8df1c31/src/init.cpp (L2326-L2327)).
  
For this reason, `CBlockPolicyEstimator` is not a member of `CJContext`
and its usage is fulfilled by passing it as a reference when
initializing the scheduling task.

* `CJClientManager` has not used `CConnman` or `CTxMemPool` as `const`
as existing code that is outside the scope of this PR would cast away
constness, which would be unacceptable. Furthermore, some logical paths
are taken that will grind to a halt if they are stored as `const`.

  Examples of such a call chains would be:

* `CJClientManager::DoMaintenance >
CCoinJoinClientManager::DoMaintenance > DoAutomaticDenominating >
CCoinJoinClientSession::DoAutomaticDenominating >
CCoinJoinClientSession::StartNewQueue > CConnman::AddPendingMasternode`
which modifies `CConnman::vPendingMasternodes`, which is non-const
behaviour

* `CJClientManager::DoMaintenance >
CCoinJoinClientManager::DoMaintenance > DoAutomaticDenominating >
CCoinJoin::IsCollateralValid > AcceptToMemoryPool` which adds a
transaction to the memory pool, which is non-const behaviour

* There were cppcheck [linter
failures](https://github.com/dashpay/dash/pull/5337#issuecomment-1685084688)
that seemed to be caused by the usage of `Assert` in
`coinjoin/client.h`. This seems to be resolved by backporting
[bitcoin#24714](https://github.com/bitcoin/bitcoin/pull/24714). (Thanks
@knst!)
    * Depends on #5546

fix: add missing includes and remove obsolete includes (#5562)
## Issue being fixed or feature implemented
Some headers or modules are used objects from STL without including it
directly, it cause compilation failures on some platforms for some
specific compilers such as #5554

## What was done?
Added missing includes and removed obsolete includes for `optional`,
`deque`, `tuple`, `unordered_set`, `unordered_map`, `set` and `atomic`.

Please, note, that this PR doesn't cover all cases, only cases when it
is obviously missing or obviously obsolete.

Also most of changes belongs to to dash specific code; but for cases of
original bitcoin code I keep it untouched, such as missing <map> in
`src/psbt.h`

I used this script to get a list of files/headers which looks suspicious
`./headers-scanner.sh std::optional optional`:
```bash
#!/bin/bash

set -e

function check_includes() {
    obj=$1
    header=$2
    file=$3

    used=0
    included=0

    grep "$obj" "$file" >/dev/null 2>/dev/null && used=1
    grep "include <$header>" $file >/dev/null 2>/dev/null && included=1
    if [ $used == 1 ] && [ $included == 0 ]
        then echo "missing <$header> in $file"
    fi
    if [ $used == 0 ] && [ $included == 1 ]
        then echo "obsolete <$header> in $file"
    fi
}
export -f check_includes

obj=$1
header=$2

find src \( -name '*.h' -or -name '*.cpp' -or -name '*.hpp' \) -exec bash -c 'check_includes "$0" "$1" "$2"'  "$obj" "$header"  {} \;
```

ci: adds flag -Werror=reorder for arm target (#5540)
## Issue being fixed or feature implemented
The order of members in a class/struct definition and the order of their
initialization should match. This ensures that the code is more
error-proof in cases where the order of member initializations is
important, as they may depend on each other.


Instead manual checking of member initialization better let CI handle
it.
Last PR where it's noticed:
https://github.com/dashpay/dash/pull/5531#discussion_r1299404387

## What was done?
New flag "-Werror=reorder" for `configure.ac` and fixes existing code.

## How Has This Been Tested?
Build code with `--enable-werror`

Pull request description:

  -dropmessagestest is a command line option that causes 1 in n received
  messages to be dropped. The Bitcoin P2P protocol is stateful and in
  general cannot handle messages being dropped. Dropped
  version/verack/ping/pong messages will cause the connection to time out
  and be torn down. Other dropped messages may also cause the peer to
  believe that the peer has stalled and tear down the connection.

  It seems difficult to uncover any actual issues with -dropmessagestest,
  and any coverage that could be generated would probably be easier to
  trigger with fuzz testing.

  Block-relay-only peers were introduced by #15759. According to its
  author, it was intented to make them only immune to outbound peer
  rotation-based eviction and not from all eviction as modified comment
  leans to think of.

  Clearly indicate that outbound block-relay peers aren't protected

refactor: using reference instead reference to unique_ptr with object (#5381)
## Issue being fixed or feature implemented
Many objects created and functions called by passing `const
std::unique_ptr<Obj>& obj` instead directly passing `Obj& obj`

In some cases it is indeed needed, but in most cases it is just extra
complexity that is better to avoid.

Motivation:
- providing reference to object instead `unique_ptr` is giving warranty
that there's no `nullptr` and no need to keep it in mind
- value inside unique_ptr by reference can be changed externally and
instead `nullptr` it can turn to real object later (or in opposite)
 - code is shorter but cleaner

Based on that this refactoring is useful as it reduces mental load when
reading or writing code.
`std::unique` should be used ONLY for owning object, but not for passing
it everywhere.

## What was done?
Replaced most of usages `std::unique_ptr<Obj>& obj` to `Obj& obj`.
Btw, in several cases implementation assumes that object can be nullptr
and replacement to reference is not possible.
Even using raw pointer is not possible, because the empty
std::unique_ptr can be initialized later somewhere in code.
For example, in `src/init.cpp` there's called `PeerManager::make` and
pass unique_ptr to the `node.llmq_ctx` that would be initialized way
later.
That is out of scope this PR.
List of cases, where reference to `std::unique_ptr` stayed as they are:
- `std::unique_ptr<LLMQContext>& llmq_ctx` in `PeerManagerImpl`,
`PeerManager` and `CDSNotificationInterface`
- `std::unique_ptr<CDeterministicMNManager>& dmnman` in
`CDSNotificationInterface`

Also `CChainState` have 3 references to `unique_ptr` that can't be
replaced too:
 - `std::unique_ptr<llmq::CChainLocksHandler>& m_clhandler;`
 - `std::unique_ptr<llmq::CInstantSendManager>& m_isman;`
- `std::unique_ptr<llmq::CQuorumBlockProcessor>&
m_quorum_block_processor;`

refactor: drop flag m_block_relay_peer and use m_addr_relay object instead (#5339)
## Issue being fixed or feature implemented
This refactoring is a follow-up changes to backport bitcoin#17164 (PR
#5314)

These changes are reduce difference in implementation for our code and
bitcoin's


## What was done?
Removed a flag m_block_relay_peer. Instead I call IsAddrRelayPeer() that
has same information now.
It changes logic introduced in #4888 due to dash-specific code.


## How Has This Been Tested?
Run unit/functional tests.

090b75c14be6b9ba2efe38a17d141c6e6af575cb p2p: Avoid allocating memory for addrKnown where we don't need it (User)

Pull request description:

  We should allocate memory for addrKnown filter only for those peers which are expected to participate in address relay.

  Currently, we do it for all peers (including SPV and block-relay-only),  which results in extra RAM where it's not needed.

  Upd:
  In future, we would still allow SPVs to ask for addrs, so allocation still will be done by default.
  However, they will be able to opt-out via [this proposal](https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2019-October/017428.html) and then we could save some more memory.
  This PR still saves memory for block-relay-only peers immediately after merging.

Pull request description:

  Carries out some remaining tidy-ups remaining after PR 15141:

  - split ValidationState into TxValidationState and BlockValidationState (commit from ajtowns)
  - various minor code style tidy-ups to the ValidationState class
  - remove the useless `ret` parameter from `ValidationState::Invalid()`
  - remove the now unused `first_invalid` parameter from `ProcessNewBlockHeaders()`
  - remove the `fMissingInputs` parameter from `AcceptToMemoryPool()`, and deal with missing inputs the same way as other errors by using the `TxValidationState` object.

  Tip for reviewers (thanks ryanofsky!): The first commit ("[validation] Add CValidationState subclasses" ) is huge and can be easier to start reviewing if you revert the rote, mechanical changes:

  Substitute the commit hash of commit "[validation] Add CValidationState subclasses" for <CommitHash> in the commands below.

  ```sh
  git checkout <CommitHash>
  git grep -l ValidationState | xargs sed -i 's/BlockValidationState\|TxValidationState/CValidationState/g'
  git grep -l ValidationResult | xargs sed -i 's/BlockValidationResult\|TxValidationResult/ValidationInvalidReason/g'
  git grep -l MaybePunish | xargs sed -i 's/MaybePunishNode\(ForBlock\|ForTx\)/MaybePunishNode/g'
  git diff HEAD^
  ```

  After that it's possible to easily see the mechanical changes with:

  ```sh
  git log -p -n1 -U0 --word-diff-regex=. <CommitHash>
  ```

a1a07cfe99fc8cee30ba5976dc36b47b1f6532ab [validation] Fix peer punishment for bad blocks (John Newbery)

Pull request description:

  We no longer send BIP 61 REJECT messages, so there's no need to set
  a REJECT code in the CValidationState object.

  Note that there is a minor bug fix in p2p behaviour here. Because the
  call to `MaybePunishNode()` in `PeerLogicValidation::BlockChecked()` only
  previously happened if the REJECT code was > 0 and < `REJECT_INTERNAL`,
  then there are cases were `MaybePunishNode()` can get called where it
  wasn't previously:

  - when `AcceptBlockHeader()` fails with `CACHED_INVALID`.
  - when `AcceptBlockHeader()` fails with `BLOCK_MISSING_PREV`.

  Note that `BlockChecked()` cannot fail with an 'internal' reject code. The
  only internal reject code was `REJECT_HIGHFEE`, which was only set in
  ATMP.

  This reverts a minor bug introduced in 5d08c9c579.

Pull request description:

  This PR is a follow up to #18038 which introduced the idea of an unbroadcast set & focuses mostly on documentation updates and test fixes. One small functionality update to not throw an expected error in `LoadMempool` when you upgrade software versions.

  #18895 is another follow up to that addresses other functionality updates.

  Background context:
  The unbroadcast set is a mechanism for the mempool to track locally submitted transactions (via wallet or RPC). The node does a best-effort of delivering the transactions to the network via retries every 10-15 minutes until either a `GETDATA` is received or the transaction is removed from the mempool.

Pull request description:

  Followup to #18038 by amitiuttarwar which introduces the unbroadcast set: "a mechanism for the mempool to track locally submitted transactions" and decreases the frequency of rebroadcast from 10-15 minutes to 12-36 hours.

  This PR addresses some of the outstanding TODOs building on top of it:
  - remove `nLastResend` logic, which is used to ensure rebroadcast doesn't happen again if no new block has been mined (makes sense in 10-15 min period, but not necessary for 12-36 hour period). (#18038 [comment](https://github.com/bitcoin/bitcoin/pull/18038#discussion_r416826914))
  - expose unbroadcast info via RPCs, for more informative queries and testing (#18038 [comment](https://github.com/bitcoin/bitcoin/pull/18038#discussion_r416837980))
  - add sanity check to verify unbroadcast transactions still exist in mempool before rebroadcasting (#18038 [comment](https://github.com/bitcoin/bitcoin/pull/18038#discussion_r416861609))

Pull request description:

  This refactor unlocks some nice potential features, such as, but not limited to:
  * Removing the fee estimates global (would avoid slightly fragile workarounds such as #18766)
  * Making the mempool optional for a "blocksonly" operation mode

  Even absent those features, the new code without the global should be easier to maintain, read and write tests for.

1168394d759b13af68acec6d5bfa04aaa24561f8 [wallet] Notify conflicted transactions in TransactionRemovedFromMempool (John Newbery)

Pull request description:

  These boost signals were added in #9371, before we had a `TransactionRemovedFromMempool` method in the validation interface. The `NotifyEntryAdded` callback was used by validation to build a vector of conflicted transactions when connecting a block, which the wallet was notified of in the `BlockConnected` CValidationInterface callback.

  Now that we have a `TransactionRemovedFromMempool` callback, we can fire that signal directly from the mempool for conflicted transactions.

  Note that #9371 was implemented to ensure `-walletnotify` events were fired for these conflicted transaction. We inadvertently stopped sending these notifications in #16624 (Sep 2019 commit 7e89994). We should probably fix that, but in a different PR.

  Currently we'll stall peers that send us an unknown INV type in a GETDATA message. Be a bit more friendly and just drop the invalid request.

  Ditto for blocks-relay-only peers that send us a GETDATA for a transaction.

  There's a test for the first part. The second is difficult to test in the functional test framework since we aren't able to make blocks-relay-only connections.

96e488aa03 Merge #18806: net: remove is{Empty,Full} flags from CBloomFilter, clarify CVE fix
1ad8ea2b73134bdd8d6b50704a019d47ad2191d8 net: remove is{Empty,Full} flags from CBloomFilter, clarify CVE fix (Sebastian Falbesoner)

Pull request description:

  The BIP37 bloom filter class `CBloomFilter` contains two flags `isEmpty`/`isFull` together with an update method with the purpose to, according to the comments, "avoid wasting cpu", i.e. the mechanism should serve as an optimization for the trivial cases of empty (all bits zero) or full (all bits one) filters.
  However, the real reason of adding those flags (introduced with commit 37c6389c5a by gmaxwell) was a _covert fix_ of [CVE-2013-5700](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-5700), a vulnerability that allowed a divide-by-zero remote node crash.
  According to gmaxwell himself (https://github.com/bitcoin/bitcoin/pull/9060#issuecomment-257749165):
  > the IsEmpty/IsFull optimizations were largely a pretextual optimization intended to make unexploitable a remote crash vulnerability (integer division by zero) that existed in the original bloom filtering code without disclosing it. I'm doubtful that they are all that useful. :)

  For more information on how to trigger this crash, see PR https://github.com/bitcoin/bitcoin/pull/18515 which contains a detailled description and a regression test. It has also been discussed on a [recent PR club meeting on fuzzing](https://bitcoincore.reviews/18521.html).

  The covert fix code already led to issues and PR based on the wrong assumption that the flags are there for optimization reasons (see #16886 and #16922). This PR gets rid of the flags and the update method and just focuses on the CVE fix itself, i.e. it can be seen as a revert of the covert fix commit modulo the actual fix.

  This is needed because in the future, the too-broad `-whitelist*` settings (they either include *all* permission flags or apply to *all* peers) might be deprecated to require the permission flags to be enumerated.

  Alternatively, in the future there could be an RPC to set the net permission flags on an existing connection, in which case the `-whitelist*` terminology is of no help.

<!--- Why is this change required? What problem does it solve? -->
<!--- If it fixes an open issue, please link to the issue here. -->
https://github.com/dashpay/dash/issues/4966

## What was done?
Serialization now depends on the protocol version, and we use an updated
serialization that is spv friendly for the new version

## How Has This Been Tested?
hasn't

## Breaking Changes
this should be backwards compatible, but this likely should get some
release notes.

b0518f0796 Merge #17985: net: Remove forcerelay of rejected txs
facb71576cd4d2e90fd03e09d29b42fa3d730e8c net: Remove forcerelay of rejected txs (MarcoFalke)

Pull request description:

  This removes the code that supposedly handled the forced relay of txs from a permissioned peer that were rejected from our mempool. The removal should be fine, because it is dead code for the following reasons:

  * While `RelayTransaction` enqueues the inv for all peers, the inv is never processed because it can not be found in the mempool. See 4a07233076/src/net_processing.cpp (L3862-L3866)

  * Even if the peers we intended to send the inv to can somehow reply with a getdata to the never-received inv, they won't receive the tx as a reply because it was never added to the "relay memory" (`mapRelay`)

  The dead code is (obviously) untested: https://marcofalke.github.io/btc_cov/total.coverage/src/net_processing.cpp.gcov.html#2574

  This feature was (intentionally or accidentally) removed in 4d8993b346, which was released in Bitcoin Core 0.13.0. So all currently supported versions of Bitcoin Core ship without this feature. I am not aware of any complaints about this feature or actual documented use-cases. So instead of reviving an unneeded feature, just remove the dead code.

168b781fe7f3f13b24c52a151f36de4cdd0a340a Continue relaying transactions after they expire from mapRelay (Anthony Towns)

Pull request description:

  This change allows peers to request transactions even after they've expired from mapRelay and even if they're not doing mempool requests. This is intended to allow for CPFP of old transactions -- if parent tx P wasn't relayed due to low fees, then a higher fee rate child C is relayed, peers will currently request the parent P, but we prior to this patch, we will not relay it due to it not being in mapRelay.

2a9a7c9169 Merge #17951: Use rolling bloom filter of recent block txs for AlreadyHave() check
a029e18c2bf67dd00552b0f4bbc85fa2fa5b973b Use rolling bloom filter of recent block tx's for AlreadyHave() check (Suhas Daftuar)

Pull request description:

  In order to determine whether to download or process a relayed transaction, we first try to check whether we already have the transaction -- either in the mempool, in our filter of recently rejected transactions, in our orphan pool, or already confirmed in a block.

  Prior to this commit, the heuristic for checking whether a transaction was confirmed in a block is based on whether there's a coin cache entry corresponding to the 0- or 1-index vout of the tx. While that is a quick check, it is very imprecise (eg if those outputs were already spent in another block, we wouldn't detect that the transaction has already been confirmed) -- we can do better by just keeping a rolling bloom filter of the transactions in recent blocks, which will better capture the case of a transaction which has been confirmed and then fully spent.

  This should reduce the bandwidth that we waste by requesting transactions which will not be accepted to the mempool.

  To avoid relay problems for transactions which have been included in a recent block but then reorged out of the chain, we clear the bloom filter whenever a block is disconnected.

Such nodes won't be seen as masternodes by RelayInvToParticipants otherwise so no contributions will be sent to them when they are picked as relay members which in its turn may result in other nodes PoSe-punishing us.

* Add a note about loop conditions

* llmq: Make TransactionRemovedFromMempool the last action for invalid txes, just like we do for orphans with rejected parents

Write to log, send reject msg and (maybe) punish first and only then notify IS about the tx removal. Makes it easier to reason about it when reading logs.

Merge bitcoin#15759: p2p: Add 2 outbound block-relay-only connections (#4862)
* Remove unused variable

* [refactor] Move tx relay state to separate structure

* [refactor] Change tx_relay structure to be unique_ptr

* Check that tx_relay is initialized before access

* Add comment explaining intended use of m_tx_relay

* Add 2 outbound block-relay-only connections

Transaction relay is primarily optimized for balancing redundancy/robustness
with bandwidth minimization -- as a result transaction relay leaks information
that adversaries can use to infer the network topology.

Network topology is better kept private for (at least) two reasons:

(a) Knowledge of the network graph can make it easier to find the source IP of
a given transaction.

(b) Knowledge of the network graph could be used to split a target node or
nodes from the honest network (eg by knowing which peers to attack in order to
achieve a network split).

We can eliminate the risks of (b) by separating block relay from transaction
relay; inferring network connectivity from the relay of blocks/block headers is
much more expensive for an adversary.

After this commit, bitcoind will make 2 additional outbound connections that
are only used for block relay. (In the future, we might consider rotating our
transaction-relay peers to help limit the effects of (a).)

* Don't relay addr messages to block-relay-only peers

We don't want relay of addr messages to leak information about
these network links.

* doc: improve comments relating to block-relay-only peers

* Disconnect peers violating blocks-only mode

If we set fRelay=false in our VERSION message, and a peer sends an INV or TX
message anyway, disconnect. Since we use fRelay=false to minimize bandwidth,
we should not tolerate remaining connected to a peer violating the protocol.

* net_processing. Removed comment + fixed formatting

* Refactoring net_processing, removed duplicated code

* Refactor some bool in a many-arguments function to enum

It's made to avoid possible typos with arguments, because some of them have default values and it's very high probability to make a mistake here.

* Added UI debug option for Outbound

* Fixed data race related to `setInventoryTxToSend`, introduced in `[refactor] Move tx relay state to separate structure`

Merge #20661: Only select from addrv2-capable peers for torv3 address relay
37fe80e6267094f6051ccf9bec0c7f1a6b9e15da Only consider addrv2 peers for relay of non-addrv1 addresses (Pieter Wuille)
83f8821a6f41854edd5c0b11deabba658890cde1 refactor: add IsAddrCompatible() to CNode (Pieter Wuille)

Pull request description:

  When selecting peers to relay an address to, only pick addrv2-capable ones if the address cannot be represented in addr(v1).

  Without this I expect that propagation of torv3 addresses over the cleartext network will be very hard for a while.

Merge #20564: Don't send 'sendaddrv2' to pre-70016 software, and send before 'verack'
1583498fb6781c01ca2f33c09319ed793964c574 Send and require SENDADDRV2 before VERACK (Pieter Wuille)
c5a89196602e43ebb1cdc9cd4f08d153419c13e1 Don't send 'sendaddrv2' to pre-70016 software (Pieter Wuille)

Pull request description:

  BIP155 defines addrv2 and sendaddrv2 for all protocol versions, but some implementations reject messages they don't know. As a courtesy, don't send it to nodes with a version before 70016, as no software is known to support BIP155 that doesn't announce at least that protocol version number.

  Also move the sending of sendaddrv2 earlier (before sending verack), as proposed in https://github.com/bitcoin/bips/pull/1043. This has the side effect that local address broadcast of torv3 will work (as it'll only trigger after we know whether or not the peer supports addrv2).

893628be0166b4096b6e52f516e0f65bb63a75a2 Drop minor GetSerializeSize template (Ben Woosley)
da74db0940720407fafaf3582bbaf9c81a4d3b4d Drop unused GetType() from CSizeComputer (Ben Woosley)

Pull request description:

  Based on conversation in #13462, it seems the serialization `GetType` has very narrow use/effect. In every case except for `CAddress`, which specifically relates to a network peer's address, not a wallet address etc., the serialized representation of an object is irrespective of its destination / type.

  This removes the unused `GetType` method from `CSizeComputer` as a step to further narrowing that use.
