Pull request description:
This PR builds on the test refactors extracted into #22306 (first 5 commits).
This PR aims to reduce addr blackholes. When we receive an `addr` message that contains 10 or less addresses, we forward them to 1-2 peers. This is the main technique we use for self advertisements, so sending to peers that wouldn't relay would effectively "blackhole" the trickle. Although we cannot prevent this in a malicious case, we can improve it for the normal, honest cases, and reduce the overall likelihood of occurrence. Two known cases where peers would not participate in addr relay are if they have connected to you as a block-relay-only connection, or if they are a light client.
This implementation defers initialization of `m_addr_known` until it is needed, then uses its presence to decide if the peer is participating in addr relay. For outbound (not block-relay-only) peers, we initialize the filter before sending the initial self announcement when processing their `version` message. For inbound peers, we initialize the filter if/when we get an addr related message (`ADDR`, `ADDRV2`, `GETADDR`). We do NOT initialize the filter based on a `SENDADDRV2` message.

Pull request description:
This is a very late follow-up PR to #10618, which removed the constant `MAX_BLOCK_BASE_SIZE` from the core implementation about four years ago (see also #10608 in why it was considered confusing and superfluous).
Since there is also no point in still keeping it in the functional test framework, the PR switches to weight-based accounting on the relevant test code parts and use `MAX_BLOCK_WEIGHT` instead for the block limit checks. To prepare that, the first two commits introduce `get_weight()` helpers for the classes CTransaction and CBlock, respectively.

8a2b58db9e test: fix segwit terminology (s/witness_program/witness_script/) (Sebastian Falbesoner)
Pull request description:
This PR fixes wrong uses of the term "witness program", which according to [BIP141](https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki#Witness_program) is defined as follows:
> A scriptPubKey (or redeemScript as defined in BIP16/P2SH) that consists of a 1-byte push opcode (for 0 to 16) followed by a data push between 2 and 40 bytes gets a new special meaning. The value of the first push is called the "version byte". **The following byte vector pushed is called the "witness program".**
In most cases where "witness program" is used in tests (concerns comments, variable names and in one instance even a function name) what we really want to denote is the "witness script". Thanks to [MarcoFalke for pointing this out in a review comment](https://github.com/bitcoin/bitcoin/pull/22363#discussion_r666794261)!
Some historical background: At the time when the P2P segwit tests were first introduced (commit 330b0f31ee, PR #8149), the term "witness program" was not used consistently in BIP141: https://bitcoin.stackexchange.com/questions/46451/what-is-the-precise-definition-of-witness-program
This was fixed in PR https://github.com/bitcoin/bips/pull/416 later.
So in some way, this PR can be seen as a very late follow-up to the BIP141 fix that also reflects these changes in the tests.

When starting up with a populated addrman, ThreadDNSAddressSeed adds a delay
during which time the node may be able to connect to some peers. This commit
tests the delay changes based on the number of addresses in the addrman.
Test that passing conflicting parameters for the two causes a startup error.
This logic also impacts -connect, which soft sets -dnsseed, so add a test for
that too.
When a node is able to properly shutdown, it will persist its block-relay-only
connections to the addrman. On startup, it will attempt to reconnect to these
anchors. Since block-relay-only connections do not participate in ADDR relay,
succesful connections are insufficient to skip querying the DNS seeds.
This test fails prior to the changes in #22013.

This commit introduces a DNS seed to the regest chain params in order to add
coverage to the DNS querying logic.
The first test checks that we do not query DNS seeds if we are able to
succesfully connect to 2 outbound connections. Since we participate in ADDR
relay with those connections, including sending a GETADDR message during the
VERSION handshake, querying the DNS seeds is unnecessary.

Pull request description:
This PR's goal is to prepare the functional test `feature_rbf.py` for more MiniWallet usage. It first gets rid of unused initialization code (I guess that was needed at times when the nodes were still in IBD at the start of tests?), then makes the MiniWallet instance introduced in #22210 available for all sub-tests, and finally, uses that instance in the first sub-test `test_simple_doublespend`.
Note that the same idea of replacing the `make_utxo` calls with MiniWallet can be also applied to other sub-tests too; this just serves as a first proof-of-concept.

8ca51af1ec test: Disable automatic connections by default (Martin Zumsande)
Pull request description:
A node normally doesn't make automatic connections to peers in the functional tests because neither DNS seeds nor hardcoded peers are available on regtest. However, when random entries are inserted into addrman as part of a functional test (e.g. while testing addr relay), `ThreadOpenConnections` will periodically try to connect to them, resulting in log entries such as:
`[opencon] [net.cpp:400] [ConnectNode] trying connection 18.166.1.1:8333 lastseen=0.0hrs`
I don't think it's desirable that functional tests try to connect to random computers on the internet, aside from the possibility that at some point in time someone out there might actually answer in a way to ruin a test.
This PR fixes this problem by disabling `ThreadOpenConnections` by adding `-connect=0` to the default args, and adding exceptions only when needed for the test to pass.

This test checks that we only relay addresses with inbound peers who have sent
us an addr related message. Uses a combination of GETADDR and ADDR to verify
when peers are eligible.
Use SetupAddressRelay to only initialize `m_addr_known` as needed. For outbound
peers, we initialize the filter before sending our self announcement (not
applicable for block-relay-only connections). For inbound peers, we initialize
the filter when we get an addr related message (ADDR, ADDRV2, GETADDR).
These changes intend to mitigate address blackholes. Since an inbound peer has
to send us an addr related message to become eligible as a candidate for addr
relay, this should reduce our likelihood of sending them self-announcements.
Use an init param to make clear whether a getaddr message should be sent when
the P2PConnection receives a version message. These changes are in preparation
for upcoming commits that modify the behavior of a bitcoind node and the test
framework.

f685a13bef doc: GetTransaction()/getrawtransaction follow-ups to #22383 (John Newbery)
abc57e1f08 refactor: move `GetTransaction(...)` to node/transaction.cpp (Sebastian Falbesoner)
Pull request description:
~This PR is based on #22383, which should be reviewed first~ (merged by now).
In [yesterday's PR review club session to PR 22383](https://bitcoincore.reviews/22383), the idea of moving the function `GetTransaction(...)` from src/validation.cpp to src/node/transaction.cpp came up. With this, the circular dependency "index/txindex -> validation -> index/txindex" is removed (see change in `lint-circular-dependencies.sh`). Thanks to jnewbery for suggesting and to sipa for providing historical background.
Relevant IRC log:
```
17:52 <jnewbery> Was anyone surprised that GetTransaction() is in validation.cpp? It seems to me that node/transaction.cpp would be a more appropriate place for it.
17:53 <raj_> jnewbery, +1
17:53 <stickies-v> agreed!
17:54 <glozow> jnewbery ya
17:54 <jnewbery> seems weird that validation would call into txindex. I wonder if we remove this function, then validation would no longer need to #include txindex
17:54 <sipa> GetTransaction predates node/transaction.cpp, and even the generic index framework itself :)
17:55 <sipa> (before 0.8, validation itself used the txindex)
17:55 <jnewbery> (and GetTransaction() seems like a natural sibling to BroadcastTransaction(), which is already in node/transaction.cpp)
17:55 <jnewbery> sipa: right, this is not meant as a criticism of course. Just wondering if we can organize things a bit more rationally now that we have better separation between things.
17:55 <sipa> jnewbery: sure, just providing background
17:56 <sipa> seems very reasonable to move it elsewhere now
```

This prevents the node from trying to connect to random IPs on the internet
while running the functional tests. Exceptions are added when required for
the test to pass.
Without this check, the tests would also pass if the CSV and
CLTV activation heights are not reached yet (e.g. if the .generate()
calls before are removed), as the operations OP_CSV and OP_CLTV
simply behave as NOPs.
Also fixes a comment in the sub-test `test_signing_with_cltv()`.
During initial sync after startup the gettxoutsetinfo RPC will still return an error while catching up. However, after the initial sync the index will not error immediately anymore when it's in the process of syncing to the tip while being called. Instead it will block until synced and then return the response.

Removing `RewindBlockIndex()` in #21009 allows the following:
- removal of tests using `segwitheight=-1` in `p2p_segwit.py`.
- move `test_upgrade_after_activation()` out of `p2p_segwit.py` reducing runtime
- in turn, that allows us to drop support for `-segwitheight=-1`, which is only supported for that test.
- that allows us to always set `NODE_WITNESS` in our local services. The only reason we don't do that is to support `-segwitheight=-1`.
- that in turn allows us to drop all of the `GetLocalServices() & NODE_WITNESS` checks inside `net_processing.cpp`, since our local services would always include `NODE_WITNESS`

9b85a5e2f7 tests: Test for dumpwallet lock order issue (Andrew Chow)
25d99e6511 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`.

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.

b6c5d1e450 p2p: AddrFetch - don't disconnect on self-announcements (Martin Zumsande)
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.

Keeping the README in one file so that it's easy to search through. Will add more jumping links later so navigation is easier.
Current TODOs:
- [x] Shell installer option: prompt user to re-login for `/etc/profile.d` entry to be picked up
- [x] Binary tarball option: prompt user to create `/etc/profile.d` entry and re-login
- [x] Fanquake docker option: complete section
- [x] Arch Linux AUR option: prompt to start `guix-daemon-latest` unit after finishing "optional setup" section
- [x] Building from source option: Insert dependency tree diagram that I made
- [x] Building from source option: redo sectioning, kind of a mess right now
- [x] Optional setup: make clear which parts are only needed if building from source
- [x] Workaround 1 for GnuTLS: perhaps mention how to remove Guix build farm's key
- [x] Overall (after everything): Make the links work.
Note to self: wherever possible, tell user how to check that something is true rather than branching by installation option.

ACK fac4814106 - going to go ahead and merge this now. It's a lot of documentation, and could probably be nit-picked / improved further, however, that can continue over the next few weeks. I'm sure more (backportable) improvements / clarifications will be made while we progress through RCs towards a new release.

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.

By whitelisting the peers via -whitelist, the inventory is transmissioned
immediately rather than on average every 5 seconds, speeding up the test by at
least a factor of two:

with this PR:
$ time ./wallet_listtransactions.py
...
0m14.93s real 0m01.68s user 0m01.87s system
This commit also moves the wallet_listtransactions tests into the < 30s group.
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.

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".

2feec3ce31 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.

fdb48163bf [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 08067aebfd) 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

1f449586a9 test: add `bad-txns-prevout-null` test to mempool_accept.py (Sebastian Falbesoner)
aa0a5bb70d test: add `bad-txns-prevout-null` test case to invalid_txs.py (Sebastian Falbesoner)
Pull request description:
This simple PR adds missing tests for the reject reason `bad-txns-prevout-null`, which is thrown in the function `CheckTransaction()`: a62fc35a15/src/consensus/tx_check.cpp (L52-L54)
Basically this condition is met for non-coinbase transactions (the code snippet above only hits if `!tx.IsCoinBase()`) with coinbase-like outpoints, i.e. hash=0, n=0xffffffff.
Can be tested by running the functional tests `feature_block.py`, `p2p_invalid_tx.py` and `mempool_accept.py`. Not sure if the redundancy in the tests is desired (I guess it would make sense if the mempool acceptance test also makes use of the invalid_txs templates?).

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.
This reject reason is triggered for non-coinbase transactions with
a coinbase-like outpoint, i.e. hash=0, n=0xffffffff.
Note that the invalid tx templates are currently used in the
functional tests feature_block.py and p2p_invalid_tx.py.
The constant `MAX_BLOCK_BASE_SIZE` has been removed from the
core implementation years ago due to being confusing and
superfluous, as it is implied by the block weight limit (see
PRs #10618 and #10608). Since there is also no point in
still keeping it in the functional test framework, we switch
to weight-based accounting on the relevant test code parts
and use `MAX_BLOCK_WEIGHT` instead for the block limit
checks.
c4ddee64c7 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))
{
return state.Invalid(TxValidationResult::TX_MEMPOOL_POLICY, "insufficient fee",

bf68ebc1cd 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).
