7524b6479c Add tests for generateblock (Andrew Toth)
dcc8332543 Add generateblock rpc (Andrew Toth)
Pull request description:
The existing block generation rpcs for regtest, `generatetoaddress` and `generatetodescriptor`, mine everything in the mempool up to the block weight limit. This makes it difficult to test a system for several scenarios where a different set of transactions are mined. For example:
- Testing the common scenario where a transaction is replaced in the mempool but the replaced transaction is mined instead.
- Testing for a double-spent transaction where a transaction that conflicts with the mempool is mined.
- Testing for non-standard transactions that are mined.
- Testing the scenario where several blocks are mined without a specific transaction in the mempool being included in a block.
This PR introduces a new rpc, `generateblock`, that takes an array of raw transactions and txids and mines only those and the coinbase. Any txids must be in the mempool, but the raw txs can be anything conforming to consensus rules. The coinbase can be specified as either an address or descriptor.
This reopens#17653 since it was closed by mistake.
Thanks to instagibbs for code suggestions that I used here.

5df0877f91 test: update and harden interface_bitcoin_cli tests (Jon Atack)
75019774c9 cli -getinfo: use getbalances instead of deprecated getwalletinfo balance (Jon Atack)
Pull request description:
Extracted from #18453 to preserve that PR as a discussion on multiwallet RPC/CLI.
This PR updates `bitcoin-cli -getinfo` to fetch the wallet balance from `getbalances` in order to no longer depend on `getwalletinfo.balance` which was deprecated a year ago in facfb41.
I found this when removing the getwalletinfo() `balance`, `unconfirmed_balance`, and `immature_balance` fields to see what broke from depending on them.
I didn't see any perceivable change in `-getinfo` run time from the change.
Test coverage for this change is provided by `test/functional/interface_bitcoin_cli.py`, which the second commit updates to (a) no longer depend on getwalletinfo.balances and (b) test the -getinfo blockcount and balance fields against non-default, non-zero values.

cd3b1569d9 Correctly compute redeemScript from witnessScript for signrawtransaction (Andrew Chow)
Pull request description:
`ParsePrevouts` uses `GetScriptForWitness` on the given witnessScript to find the corresponding redeemScript. This is incorrect when the witnessScript is either a P2PK or P2PKH script as it returns the corresponding P2WPK script instead of turning the witnessScript into a P2WSH script. Instead this should make the script a `WitnessV0ScriptHash` destination and get the script for that.
Test cases are also added. These will fail on master with a `redeemScript does not correspond to witnessScript`

0ed2d8e07d test: add BIP37 remote crash bug [CVE-2013-5700] test to p2p_filter.py (Sebastian Falbesoner)
Pull request description:
Integrates the missing message type `filteradd` to the test framework and checks that the BIP37 implementation is not vulnerable to the "remote crash bug" [CVE-2013-5700](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-5700) anymore. Prior to v.0.8.4, it was possible to trigger a division-by-zero error on the following line in the function `CBloomFilter::Hash()`:
f0d6487e29/src/bloom.cpp (L45)
By setting a zero-length filter via `filterload`, `vData.size()` is 0, so the modulo operation above, called on any .insert() or .contains() operation then crashed the node. The test uses the approach of just sending an arbitrary `filteradd` message after, which calls `CBloomFilter::insert()` (and in turn `CBloomFilter::Hash()`) on the node. The vulnerability was fixed by commit 37c6389c5a (an intentional covert fix, [according to gmaxwell](https://github.com/bitcoin/bitcoin/issues/18483#issuecomment-608224095)), which introduced flags `isEmpty`/`isFull` that wouldn't call the `Hash()` member function if `isFull` is true (set to true by default constructor).
To validate that the test fails if the implementation is vulnerable, one can simply set the flags to false in the member function `UpdateEmptyFull()` (that is called after a filter received via `filterload` is constructed), which activates the vulnerable code path calling `Hash` in any case on adding or testing for data in the filter:
```diff
diff --git a/src/bloom.cpp b/src/bloom.cpp
index bd6069b..ef294a3 100644
--- a/src/bloom.cpp
+++ b/src/bloom.cpp

7a6627ae87 Fix mining to an invalid target + ensure that a new block has the correct hash internally in Python tests (Samer Afach)
Pull request description:
Test with block 47 in the `feature_block.py` creates a block with a hash higher than the target, which is supposed to fail. Now two issues exist there, and both have low probability of showing up:
1. The creation is done with `while (hash < target)`, which is wrong, because hash = target is a valid mined value based on the code in the function `CheckProofOfWork()` that validates the mining target:
```
if (UintToArith256(hash) > bnTarget)
return false;
```
2. As we know the hash stored in CBlock class in Python is stateful, unlike how it's in C++, where calling `CBlock::GetHash()` will actively calculate the hash and not cache it anywhere. With this, blocks that come out of the method `next_block` can have incorrect hash value when `solve=False`. This is because the `next_block` is mostly used with `solve=True`, and solving does call the function `rehash()` which calculates the hash of the block, but with `solve=False`, nothing calls that method. And since the work to be done in regtests is very low, the probably of this problem showing up is very low, but it practically happens (well, with much higher probability compared to issue No. 1 above).
This PR fixes both these issues.

Pull request description:
Replacing boost functionality with C++11 stuff.
Motivated by #18227, but should stand alone. Changing from `boost::condition_var` to `std::condition_var` means `threadGroup.interrupt_all` isn't enough to interrupt `serviceQueue` anymore, so that means calling `stop()` before `join_all()` is needed. And the existing reverselock.h code doesn't work with sync.h's DebugLock code (because the reversed lock won't be removed from `g_lockstack` which then leads to incorrect potential deadlock warnings), so I've replaced that with a dedicated class and macro that's aware of our debug lock behaviour.

Pull request description:
This PR builds on PR #16702 to add functional tests / sanity checks and user-facing refinements for passing `-asmap` to configure ASN-based IP bucketing in addrman. As per our review discussion in that PR, the idea here is to handle aspects like functional tests and config arg handling that can help the PR be merged while enabling the author to focus on the bucketing itself.
- [x] add feature functional tests to verify node behaviour and debug log output when launching
- `bitcoind` with no `-asmap` arg
- `bitcoind -asmap=RELATIVE_FILENAME` to the unit test data skeleton asmap
- `bitcoind -asmap` with no filename specified using the default asmap file
- `bitcoind -asmap` with no filename specified and a missing default asmap file
- [x] add the ability to pass absolute path filenames to the `-asmap` config arg in addition to datadir-relative path filenames as per https://github.com/bitcoin/bitcoin/pull/16702#discussion_r361300447, and add test coverage
- [x] separate the asmap file finding and parsing checks, which allows adding tests for the case of a found but unparseable or empty asmap
- [x] add test for an empty asmap
- [x] various asmap fixups
- [x] move the asmap init code earlier in the init process to provide immediate feedback when passing an `-asmap` config arg. This speeds up the `feature_asmap` functional test from 60 to 5 seconds! Credit to Wladimir J. van der Laan for the suggestion.

and update feature_asmap.py and test_runner.py
This commit moves the asmap init.cpp code from the end of "Step 12: start node"
to "Step 6: network initialization" to provide feedback on passing an -asmap
config arg much more quickly. This change speeds up the feature_asmap.py
functional test file from 60 to 5 seconds by accelerating the 2 tests that use
`assert_start_raises_init_error`.
Credit to Wladimir J. van der Laan for the suggestion.
- move asmap #includes to sorted positions in addrman and init (move-only)
- remove redundant quotes in asmap InitError, update test
- remove full stops from asmap logging to be consistent with debug logging,
update tests
to verify node behaviour and debug log when launching bitcoind in these cases:
1. `bitcoind` with no -asmap arg, using /16 prefix for IP bucketing
2. `bitcoind -asmap=<relative path>`, using the unit test skeleton asmap
3. `bitcoind -asmap/-asmap=` with no file specified, using the default asmap
4. `bitcoind -asmap` with no file specified, and a missing default asmap file
The tests are order-independent. The slowest test (missing default asmap file)
is placed last.
1ef28b4f7c Make AnalyzePSBT next role calculation simple, correct (Gregory Sanders)
Pull request description:
Sniped test and alternative to https://github.com/bitcoin/bitcoin/pull/18220
Sjors documenting the issue:
```
A PSBT signed by ColdCard was analyzed as follows (see #17509 (comment))
{
"inputs": [
{
"has_utxo": true,
"is_final": false,
"next": "finalizer"
}
],
"estimated_vsize": 141,
"estimated_feerate": 1e-05,
"fee": 1.41e-06,
"next": "signer"
}
I changed AnalyzePSBT so that it returns "next": "finalizer" instead.
```
It makes it much clearer that the role has been decided before hitting the `calc_fee` block, and groups all state-deciding in one spot instead of 2.
Note that this assumes that PSBT roles are a complete ordering, which for now and in the future seems to be a correct assumption.

this also fixes a bug that was uncovered with this checks:
for the BIP112 version 1 tx tests, certain txs (bip112txs_vary_OP_CSV_v1) have
been sent twice due to a typo, leading also to a failure as expected but for the
wrong reason
With BIP112 activated, the operation OP_CHECKSEQUENCEVERIFY (former OP_NOP3)
leads to script interpreter termination with an error if one of the following
conditions is true:
-> stack is empty
-> top item on stack is negative (< 0)
-> top item on stack has disable flag unset and at least one of
four other conditions is true (contains the core CSV logic)
This commits adds the missing empty stack failure test to the functional test
by prepending a valid scriptSig with just OP_CHECKSEQUENCEVERIFY. If BIP112 is
inactive, the operator just behaves as a NOP (for both tx versions 1 and 2) and
the transaction remains valid -- if it is active, the tx is invalid due to an
empty stack (for both tx versions 1 and 2, as well).

Pull request description:
This is a follow-up PR to #17435, testing the custom descendant limit, passed by the argument `-limitdescendantcount`. ~~It was more tricky than expected, mainly because we don't know for sure at which point node1 has got all the transactions broadcasted from node0 (for the ancestor test this wasn't a problem since the txs were immediately available through `invalidateblock`) -- a simple `sync_mempools()` doesn't work here since the mempool contents are not equal due to different ancestor/descendant limits.

1. ~~wait until the mempool has the _expected_ tx count (see conditions below)~~
2. ~~after that, wait some time and get sure that the mempool contents haven't changed in-between~~

- all txs in node1 mempool are a subset of txs in node0 mempool

facb71576c 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.

> _Bit of a privacy issue_: let's say person A and B are about to spend from a multisig address, sending everything to person A. Person A gives their address to person B, their wallet wallet creates a PSBT, but doesn't sign it. Wallet A then calls `walletprocesspsbt` which signs it and _spontaneously adds the master_fingerprint and bip32 path_. Same issue with `walletcreatefundedpsbt`.

> Adding `bip32_derivs` should probably be opt-in.
In practice I find this default quite annoying because I forget it and end up with a confused hardware wallet.
More importantly, in the multisig example I provided, it's actually essential for the other side to know the derivation details (in addition to an xpub). This allows them to check that change is going to an address you can still co-sign for (because the spending policy is unchanged except for an index).

d6d2602a32 add: test that transactions expire from mempool (0xb10c)
Pull request description:
This adds the functional test `mempool_expiry.py` covering mempool transaction expiry. Both the default `DEFAULT_MEMPOOL_EXPIRY` of 336 hours (two weeks, set in #9312) and the user definable mempool expiry via the `-mempoolexpiry=<n>` command line option are tested. The test checks that descendants of expired transactions are removed as well.
*Notes for reviewers*
- `LimitMempoolSize()` (which is the only caller of `CTxMemPool::Expire()`) is only called when a transaction is added to the mempool. In order to test expiry of a transaction-that-should-expire, the mocktime is set and a random transaction is broadcast to trigger `LimitMempoolSize()`. The transaction-that-should-expire is then checked for expiry. LMK if there is another way, but I don't think there is.

This would have caught `util: Avoid potential uninitialized read in FormatISO8601DateTime(int64_t) by checking gmtime_s/gmtime_r return value` (#18162) and similar cases.

This tests that a mempool transaction expires after a given timeout
and its children are removed as well.
Both the default expiry timeout defied by DEFAULT_MEMPOOL_EXPIRY and
a user definable expiry timeout via the -mempoolexpiry=<n> command
line argument (<n> is the timeout in hours) are tested.

005f8a92cc wallet: Improve LegacyScriptPubKeyMan::CanProvide script recognition (Russell Yanofsky)
Pull request description:
Make `LegacyScriptPubKeyMan::CanProvide` method able to recognize p2sh scripts when the redeem script is present in the `mapScripts` map without the p2sh script also having to be added to the `mapScripts` map. This restores behavior prior to #17261, which I think broke backwards compatibility with old wallet files by no longer treating addresses created by `addmultisigaddress` calls before #17261 as solvable.
The reason why tests didn't fail with the CanProvide implementation in #17261 is because of a workaround added in 4a7e43e846 "Store p2sh scripts in AddAndGetDestinationForScript", which masked the problem for new `addmultisigaddress` RPC calls without fixing it for multisig addresses already created in old wallet files.
This change adds a lot of comments and allows reverting commit 4a7e43e846 "Store p2sh scripts in AddAndGetDestinationForScript", so the `AddAndGetDestinationForScript()` function, `CanProvide()` method, and `mapScripts` map should all be more comprehensible

Pull request description:
Ensure prevector data is appropriately aligned. Earlier discussion in #17530.
**Edit laanwj**: In contrast to #17530, it does this without increase in size of any of the coin cache data structures (x86_64, clang)
| Struct | (size,align) before | (size,align) after |
| ------------- | ------------- | ------- |
| Coin | 48, 8 | 48, 8 |

Pull request description:
This updates leveldb to currently newest upstream commit 0c40829872:
- CRC32C hardware acceleration is now an external library [crc32c](https://github.com/google/crc32c). This adds acceleration on ARM, and should be faster on x86 because of using prefetch. It also makes it easy to support similar instruction sets on other platforms in the future.
- Thread handling uses C++11, instead of platform specific code.
- Native windows environment was added. No need to maintain our own hacky one, anymore.
- Upstream now builds using CMake. This doesn't mean we need to use that (phew), but internal configuration changed to a a series of checks, instead of OS profiles. This means the blanket error "Cannot build leveldb for $host. Please file a bug report' is removed.
All changes: a53934a3ae...0c40829872
Pretty much all our changes have been subsumed by upstream, so we figured it was cleaner to start over with a new branch from upstream with the still-relevant patches applied: https://github.com/bitcoin-core/leveldb/tree/bitcoin-fork-new
There's quite some testing to be done (see below). See https://github.com/bitcoin-core/leveldb/issues/25 and https://github.com/bitcoin-core/leveldb/pull/26 for more history and context.
TODO:
- [x] Subtree `crc32c`
- [x] Make linters happy about crc32 subtree
- [x] Integrate `crc32c` library into build system
- [x] MSVC build system
