8a2b58db9ee6a14d36b5d8e430b35f18e7c7b0c5 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 330b0f31ee5719d94f9e52dfc83c5d82168241f9, 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.

84c874794cc1e1aa48f2edf08c355ec2a5696cb6 test: remove unneeded initialization code in feature_rbf.py (Sebastian Falbesoner)
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.

in the functional tests
8ca51af1ece371b6f1bdb88b96f16020cc787d13 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.

Pull request description:
This PR improves the test `wallet_listtransactions.py` in three ways:
* speeds up runtime by a factor of 2-3x by using the good ol' immediate tx relay trick (`-whitelist=noban@127.0.0.1`)
* removes unneeded/redundant code
* adds log messages, mostly by turning comments into `self.log.info(...)` calls

Remove proxy.url assignment:

|
|
This will speed up the test a bit and avoid potential .generate() RPC
timeouts (in sub-test `test_signing_with_cltv()`) on slower machines.
|
|
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.

Pull request description:
Builds on #21009 and makes progress on remaining items in #17862
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`

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.

b6c5d1e450dde6a54bd785504c923adfb45c7060 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.

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.

0d64b8f709b4655d8702f810d4876cd8d96ded82 Rate limit the processing of incoming addr messages (Pieter Wuille)
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:
before:
$ time ./wallet_listtransactions.py
...
0m40.25s real 0m01.74s user 0m01.70s system
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.

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.
