Merge bitcoin/bitcoin#22492: wallet: Reorder locks in dumpwallet to avoid lock order assertion
9b85a5e2f7e003ca8621feaac9bdd304d19081b4 tests: Test for dumpwallet lock order issue (Andrew Chow)
25d99e6511d8c43b2025a89bcd8295de755346a7 Reorder dumpwallet so that cs_main functions go first (Andrew Chow)

Pull request description:

  When a wallet is loaded which has an unconfirmed transaction in the mempool, it will end up establishing the lock order of cs_wallet -> cs_main -> cs_KeyStore. If `dumpwallet` is used on this wallet, then a lock order of cs_wallet -> cs_KeyStore -> cs_main will be used, which causes a lock order assertion. This PR fixes this by reordering `dumpwallet` and `GetKeyBirthTimes` (only used by `dumpwallet`). Specifically, in both functions, the function calls which lock cs_main are done prior to locking cs_KeyStore. This avoids the lock order issue.

  Additionally, I have added a test case to `wallet_dump.py`. Of course testing this requires `--enable-debug`.

  Fixes #22489

Pull request description:

  1. Only add a transaction to the unbroadcast set when it's added to the mempool

      Currently, if BroadcastTransaction() is called to rebroadcast a
      transaction (e.g. by ResendWalletTransactions()), then we add the
      transaction to the unbroadcast set. That transaction has already been
      broadcast in the past, so peers are unlikely to request it again,
      meaning RemoveUnbroadcastTx() won't be called and it won't be removed
      from m_unbroadcast_txids.

      Net processing will therefore continue to attempt rebroadcast for the
      transaction every 10-15 minutes. This will most likely continue until
      the node connects to a new peer which hasn't yet seen the transaction
      (or perhaps indefinitely).

      Fix by only adding the transaction to the broadcast set when it's added to the mempool.

  2. Allow rebroadcast for same-txid-different-wtxid transactions

      There is some slightly unexpected behaviour when:

      - there is already transaction in the mempool (the "mempool tx")
      - BroadcastTransaction() is called for a transaction with the same txid
        as the mempool transaction but a different witness (the "new tx")

      Prior to this commit, if BroadcastTransaction() is called with
      relay=true, then it'll call RelayTransaction() using the txid/wtxid of
      the new tx, not the txid/wtxid of the mempool tx. For wtxid relay peers,
      in SendMessages(), the wtxid of the new tx will be taken from
      setInventoryTxToSend, but will then be filtered out from the vector of
      wtxids to announce, since m_mempool.info() won't find the transaction
      (the mempool contains the mempool tx, which has a different wtxid from
      the new tx).

      Fix this by calling RelayTransaction() with the wtxid of the mempool
      transaction in this case.

  The third commit is a comment/whitespace only change to tidy up the BroadcastTransaction() function.

Pull request description:

  AddrFetch connections (old name: oneshots) are intended to be short-lived connections on which we ask a peer for addresses via `getaddr` and disconnect after receiving them.

  This is done by disconnecting after receiving the first `addr`. However, it is no longer working as intended, because nowadays, the first `addr` a typical bitcoin core node sends is its self-announcement.
  So we'll disconnect before the peer gets a chance to answer our `getaddr`.

  I checked that this affects both `-seednode` peers specified manually, and DNS seeds when AddrFetch is used as a fallback if DNS doesn't work for us.

  The current behavior of getting peers via AddrFetch when starting with an empty addrman would be to connect to the peer, receive its self-announcement and add it to addrman, disconnect, reconnect to the same peer again as a full outbound (no other addresses in addrman) and then receive more `addr`. This is silly and not in line with AddrFetch peer being intended to be short-lived peers. 

  Fix this by only disconnecting after receiving an `addr` message of size > 1.

  [Edit] As per review discussion, this PR now also adds a timeout after which we disconnect if we haven't received any suitable `addr`, and a functional test.

9b85a5e2f7 tests: Test for dumpwallet lock order issue
Adds a test for the condition which can trigger a lock order assertion.
Specifically, there must be an unconfirmed transaction in the mempool
which belongs to the wallet being loaded. This will establish the order
of cs_wallet -> cs_main -> cs_KeyStore. Then dumpwallet is called on
that wallet. Previously, this would have used a lock order of cs_wallet
-> cs_KeyStore -> cs_main, but this should be fixed now. The test
ensures that.

Pull request description:

  The rate at which IP addresses are rumoured (through ADDR and ADDRV2 messages) on the network seems to vary from 0 for some non-participating nodes, to 0.005-0.025 addr/s for recent Bitcoin Core nodes. However, the current codebase will happily accept and process an effectively unbounded rate from attackers. There are measures to limit the influence attackers can have on the addrman database (bucket restrictions based on source IPs), but still - there is no need to permit them to feed us addresses at a rate that's orders of magnitude larger than what is common on the network today, especially as it will cause us to spam our peers too.

  This PR implements a [token bucket](https://en.wikipedia.org/wiki/Token_bucket) based rate limiter, allowing an average of 0.1 addr/s per connection, with bursts up to 1000 addresses at once. Whitelisted peers as well as responses to GETADDR requests are exempt from the limit. New connections start with 1 token, so as to not interfere with the common practice of peers' self-announcement.

0d64b8f709 Rate limit the processing of incoming addr messages
While limitations on the influence of attackers on addrman already
exist (affected buckets are restricted to a subset based on incoming
IP / network group), there is no reason to permit them to let them
feed us addresses at more than a multiple of the normal network
rate.

This commit introduces a "token bucket" rate limiter for the
processing of addresses in incoming ADDR and ADDRV2 messages.
Every connection gets an associated token bucket. Processing an
address in an ADDR or ADDRV2 message from non-whitelisted peers
consumes a token from the bucket. If the bucket is empty, the
address is ignored (it is not forwarded or processed). The token
counter increases at a rate of 0.1 tokens per second, and will
accrue up to a maximum of 1000 tokens (the maximum we accept in a
single ADDR or ADDRV2). When a GETADDR is sent to a peer, it
immediately gets 1000 additional tokens, as we actively desire many
addresses from such peers (this may temporarily cause the token
count to exceed 1000).

The rate limit of 0.1 addr/s was chosen based on observation of
honest nodes on the network. Activity in general from most nodes
is either 0, or up to a maximum around 0.025 addr/s for recent
Bitcoin Core nodes. A few (self-identified, through subver) crawler
nodes occasionally exceed 0.1 addr/s.

Pull request description:

  Nodes that can reach the I2P network (have set `-i2psam=`) will relay
  I2P addresses even without this patch. However, nodes that can't reach
  the I2P network will not. This was done as a precaution in
  https://github.com/bitcoin/bitcoin/pull/20119 before anybody could
  connect to I2P because then, for sure, it would have been useless.

  Now, however, we have I2P support and a bunch of I2P nodes, so get all
  nodes on the network to relay I2P addresses to help with propagation,
  similarly to what we do with Tor addresses.

  _This is an alternative to https://github.com/bitcoin/bitcoin/pull/21514, inspired by https://github.com/bitcoin/bitcoin/pull/21514#issuecomment-815049933. They are mutually exclusive. Just one of them should be merged._

  Change assumed ports for I2P to 0 (instead of the default 8333) as this is closer to what actually happens underneath with SAM 3.1 (https://github.com/bitcoin/bitcoin/pull/21514#issuecomment-812632520, https://github.com/bitcoin/bitcoin/pull/21514#issuecomment-816564719).

  Don't connect to I2P peers with advertised port != 0 (we don't specify a port to our SAM 3.1 proxy and it always connects to port = 0).

  Note, this change:
  * Keeps I2P addresses with port != 0 in addrman and relays them to others via P2P gossip. There may be non-bitcoin-core-22.0 peers using SAM 3.2 and for them such addresses may be useful.
  * Silently refuses to connect to I2P hosts with port != 0. This is ok for automatically chosen peers from addrman. Not so ok for peers provided via `-addnode` or `-connect` - a user who specifies `foo.b32.i2p:1234` (non zero port) may wonder why "nothing is happening".

  Fixes #21389

2feec3ce3130961f98ceb030951d0e46d3b9096c net: don't bind on 0.0.0.0 if binds are restricted to Tor (Vasil Dimov)

Pull request description:

  The semantic of `-bind` is to restrict the binding only to some address.
  If not specified, then the user does not care and we bind to `0.0.0.0`.
  If specified then we should honor the restriction and bind only to the
  specified address.

  Before this change, if no `-bind` is given then we would bind to
  `0.0.0.0:8333` and to `127.0.0.1:8334` (incoming Tor) which is ok -
  the user does not care to restrict the binding.

  However, if only `-bind=addr:port=onion` is given (without ordinary
  `-bind=`) then we would bind to `addr:port` _and_ to `0.0.0.0:8333` in
  addition.

  Change the above to not do the additional bind: if only
  `-bind=addr:port=onion` is given (without ordinary `-bind=`) then bind
  to `addr:port` (only) and consider incoming connections to that as Tor
  and do not advertise it. I.e. a Tor-only node.

Merge bitcoin/bitcoin#22253: validation: distinguish between same tx and same-nonwitness-data tx in mempool

fdb48163bfbf34f79dc78ffaa2bbf9e39af96687 [validation] distinguish same txid different wtxid in mempool (glozow)

Pull request description:

  On master, if you submit a transaction with the same txid but different witness to the mempool, it thinks the transactions are the same. Users submitting through `BroadcastTransaction()` (i.e. `sendrawtransaction` or the wallet) don't get notified that there's a different transaction in the mempool, although it doesn't crash. Users submitting through `testmempoolaccept()` will get a "txn-already-in-mempool" error.

  This PR simply distinguishes between `txn-already-in-mempool` and `txn-same-nonwitness-data-in-mempool`, without handling them differently: `sendrawtransaction` still will not throw, but `testmempoolaccept` will give you a different error.

  I believe the intention of #19645 is to allow full swaps of transactions that have different witnesses but identical nonwitness data. Returning a different error message + adding a test was suggested: https://github.com/bitcoin/bitcoin/pull/19645#issuecomment-705109193 so this is that PR.

Pull request description:

  PR #18788 (commit 08067aebfd7e838e6ce6b030c31a69422260fc6f) introduced functions to generate output scripts for various types. This PR replaces all manual CScript creations in the P2PKH, P2SH, P2WPKH, P2WSH formats with those helpers in order to increase readability and maintainability over the functional test codebase. The first commit fixes a bug in the wallet_util helper module w.r.t. to P2SH-P2WSH script creation (the result is not used in any test so far, hence it can still be seen as refactoring).

  The following table shows a summary of the output script patterns tackled in this PR:

  | Type | master branch  | PR branch |
  | ---------- | ------------- | ------------- |
  | P2PKH | `CScript([OP_DUP, OP_HASH160, hash160(key), OP_EQUALVERIFY, OP_CHECKSIG])` | `key_to_p2pkh_script(key)`  |
  |             | `CScript([OP_DUP, OP_HASH160, keyhash, OP_EQUALVERIFY, OP_CHECKSIG])` | `keyhash_to_p2pkh_script(keyhash)` |
  | P2SH  | `CScript([OP_HASH160, hash160(script), OP_EQUAL])`  | `script_to_p2sh_script(script)` |
  | P2WPKH | `CScript([OP_0, hash160(key)])` | `key_to_p2wpkh_script(key)` |
  | P2WSH | `CScript([OP_0, sha256(script)])` | `script_to_p2wsh_script(script)` |

  Note that the `key_to_...` helpers can't be used if an invalid key size (not 33 or 65 bytes) is passed, which is the case in some rare instances where the scripts still have to be created manually.

  Possible follow-up ideas:
  * further simplify by identifying P2SH-wrapped scripts and using `key_to_p2sh_p2wpkh_script()` and `script_to_p2sh_p2wsh_script()` helpers
  * introduce and use `key_to_p2pk_script()` helper for P2PK scripts

net: don't bind on 0.0.0.0 if binds are restricted to Tor
The semantic of `-bind` is to restrict the binding only to some address.
If not specified, then the user does not care and we bind to `0.0.0.0`.
If specified then we should honor the restriction and bind only to the
specified address.

Before this change, if no `-bind` is given then we would bind to
`0.0.0.0:8333` and to `127.0.0.1:8334` (incoming Tor) which is ok -
the user does not care to restrict the binding.

However, if only `-bind=addr:port=onion` is given (without ordinary
`-bind=`) then we would bind to `addr:port` _and_ to `0.0.0.0:8333` in
addition.

Change the above to not do the additional bind: if only
`-bind=addr:port=onion` is given (without ordinary `-bind=`) then bind
to `addr:port` (only) and consider incoming connections to that as Tor
and do not advertise it. I.e. a Tor-only node.

c4ddee64c7f80eee05a95116ef1b1dc8a7601183 test: Add test for replacement relay fee check (Antoine Riard)

Pull request description:

  This PR adds rename the `reject_reason` of our implementation of BIP125 rule 4 and adds missing functional test coverage. Note, `insufficient fee` is already the `reject_reason` of few others `PreChecks` replacement checks and as such might be confusing.

  > The replacement transaction must also pay for its own bandwidth at or above the rate set by the node's minimum relay fee setting. For example, if the minimum relay fee is 1 satoshi/byte and the replacement transaction is 500 bytes total, then the replacement must pay a fee at least 500 satoshis higher than the sum of the originals.

  ```
          // Finally in addition to paying more fees than the conflicts the
          // new transaction must pay for its own bandwidth.
          CAmount nDeltaFees = nModifiedFees - nConflictingFees;
          if (nDeltaFees < ::incrementalRelayFee.GetFee(nSize))
          {

bf68ebc1cd555f791103f81adc9111e0e55c8003 wallet: allow to import same descriptor twice (S3RK)

Pull request description:

  Rationale: allow updating existing descriptors with `importdescriptors` command.

  Currently if you run same `importdescriptors` command twice with a descriptor containing private key you will get very confusing error — `Missing required fields`. What happens is that Wallet tries to write imported private key to the disk, but it exists already so we get `DB_KEYEXIST (-30995)` from BerkelyDB. Please note, that we set `DB_NOOVERWRITE` (I guess not to lose some keys accidentally). The exception is caught in `catch (...)` in rpcdump.cpp with a generic error.

  With this PR if a descriptor is already present than we will update its activeness, internalness, label, range and next_index.
  For the range only expansion is allowed (range start can only decrease, range end increase).

Pull request description:

  Currently bech32m addresses are classfied as bech32. Because bech32m is incompatible with bech32, we need to define a new `OutputType` for it so that it can be handled correctly. This PR adds `OutputType::BECH32M`, updates all of the relevant `OutputType` classifications, and handle requests for bech32m addresses. There is now a `bech32m` address type string that can be used.

  * `tr()` descriptors now report their output type as `OutputType::BECH32M`. `WtinessV1Taproot` and `WitnessUnknown` are also classified as `OutputType::BECH32M`.
  * Bech32m addresses are completely disabled for legacy wallets. They cannot be imported (explicitly disallowed in `importaddress` and `importmulti`), will not be created when getting all destinations for a pubkey, and will not be added with `addmultisigaddress`. Additional protections have been added to `LegacyScriptPubKeyMan` to disallow attempting to retrieve bech32m addresses.
  * Since Taproot multisigs are not implemented yet, `createmultisig` will also disallow the bech32m address type.
  * As Taproot is not yet active, `DescriptorScriptPubKeyMan` cannot and will not create a `tr()` descriptor. Protections have been added to make sure this cannot occur.
  * The change address type detection algorithm has been updated to return `bech32m` when there is a segwit v1+ output script and the wallet has a bech32m `ScriptPubKeyMan`, falling back to bech32 if one is not available.

Pull request description:

  There are still many functional tests that perform conversions from a hex-string to a message object (deserialization) manually. This PR identifies all those instances and replaces them with a newly introduced helper `tx_from_hex`.

  Instances were found via
  * `git grep "deserialize.*BytesIO"`

  and some of them manually, when it were not one-liners.

  Further, the helper `ToHex` was removed and simply replaced by `.serialize().hex()`, since now both variants are in use (sometimes even within the same test) and using the helper doesn't really have an advantage in readability.

  2. hopefully fixes the test flakiness by bumping up the mocktime interval to ensure `m_next_addr_send` timer triggers

Merge bitcoin/bitcoin#22166: Add support for inferring tr() descriptors
d637a9b397816e34652d0c4d383308e39770737a Taproot descriptor inference (Pieter Wuille)
c7388e5ada394b7fe94d6263fb02e9dd28ab367e Report address as solvable based on inferred descriptor (Pieter Wuille)
29e5dd1a5b9a1879e6c3c7e153b2e6f33a79e905 consensus refactor: extract ComputeTapleafHash, ComputeTaprootMerkleRoot (Pieter Wuille)

Pull request description:

  Includes:
  * First commit from #21365, adding TaprootSpendData in SigningProvider
  * A refactor to expose ComputeTapleafHash and ComputeTaprootMerkleRoot from script/interpreter
  * A tiny change to make `getaddressinfo` report tr() descriptors as solvable (so that inferred descriptors are shown), despite not having signing code for them.
  * Logic to infer the script tree back from TaprootSpendData, and then use that to infer descriptors.

d197977ae2076903ed12ab7616a7f93e88be02e1 banman: save the banlist in a JSON format on disk (Vasil Dimov)

Pull request description:

  Save the banlist in `banlist.json` instead of `banlist.dat`.

  This makes it possible to store Tor v3 entries in the banlist on disk
  (and any other addresses that cannot be serialized in addrv1 format).

  Only read `banlist.dat` if it exists and `banlist.json` does not exist (first start after an upgrade).

  Sync the blocks before invalidating them to ensure all nodes are on the right tip. Otherwise nodes[0] might stay on the "stale" block and the test fails (intermittently)

754f134a50 wallet: Add error message to GetReservedDestination
Adds an error output parameter to all GetReservedDestination functions
so that callers can get the actual reason that a change address could
not be fetched. This more closely matches GetNewDestination. This allows
for more granular error messages, such as one that indicates that
bech32m addresses cannot be generated yet.

87a0e7a3b7 Disallow bech32m addresses for legacy wallet things
We don't want the legacy wallet to ever have bech32m addresses so don't
allow importing them. This includes addmultisigaddress as that is a
legacy wallet only RPC

Additionally, bech32m multisigs are not available yet, so disallow them
in createmultisig.

6dbe4d1072 Use BECH32M for tr() desc, WitV1Taproot, and WitUnknown CTxDests
The tr() descriptor, WitnessV1Taproot CTxDestination, and
WitnessUnknown CTxDestination are OutputType::BECH32M so they should
report as such.
