0a50019fde7781263e0c8f041d1d9dcb0dee77e8 Walk pindexBestHeader back to ChainActive().Tip() if it is invalid (Matt Corallo)
Pull request description:
Instead of keeping pindexBestHeader set to the best header we've
ever seen, reset it back to our validated tip if we find an ancestor
of it turns out to be invalid. While the name is now a bit confusing,
this matches much better with how it is used in practice, see below.
Further, this opens up more use-cases for it in the future, namely
aggressively searching for new peers in case we have discovered
(possibly via some covert channel) headers which we do not know to be
invalid, but which we cannot find block data for.
Places pindexBestHeader is used:
* Various GUI displays of the best header and getblockchaininfo["headers"],
I don't think changing this is bad, and if anything this is less confusing
in the presence of an invalid block.
* IsCurrentForFeeEstimation(): If anything I think ensuring pindexBestHeader
isn't some crazy invalid chain is better than the alternative, even in the
case where you are rejecting the current chain due to hardware error (since
hopefully in that case you won't get any new blocks anyway).
* ConnectBlock assumevalid checks: We use pindexBestHeader to check that the
block we're connecting leads to something with nMinimumChainWork (preventing
a user-set assumevalid from having bogus work) and that the block we're
connecting leads to pindexBestHeader (I'm not too worried about this one -
it's nice to "disable" assumevalid if we have a long invalid headers chain,
but I don't see it as a critical protection).
* BlockRequestAllowed() uses pindexBestHeader as its target to ensure the
requested block is within a month of the "current chain". I don't think this
is a meaningful difference, if we're rejecting the current tip we're
trivially fingerprintable anyway, and if the chain really does have a bunch
of invalid crap near the tip, using the best not-invalid header is likely a
better criteria.
* ProcessGetBlockData uses pindexBestHeader as the "current chain" definition
of whether a block request is "historical" for the purpose of bandwidth
limiting. Similarly, I don't see why this is a meaningful change.
* We use pindexBestHeader for requesting missing headers on receipt of a
headers/compact block message or block inv as well as for initial getheaders.
I think this is definitely wrong, using the best not-invalid header for such
requests is much better.
* We use pindexBestHeader to define the "current chain" for deciding when
we're close to done with initial headers sync. I don't think this is a
meaningful change.
* We use pindexBestHeader to decide if initial headers sync has timed out. If
we're rejecting the chain due to hardware error this may result in
additional cases where we ban a peer, but this is already true, so I think
its fine.

bd5a02692853f7240a4fdc593d7d0123d7916e45 Make UpdateTransactionsFromBlock use Epochs (Jeremy Rubin)
2ccb7cca4ac67198ac89bd58f5b4ae41a5163ceb Add Epoch Guards to CTXMemPoolEntry and CTxMemPool (Jeremy Rubin)
Pull request description:
UpdateTransactionsFromBlock is called during a re-org. When a re-org occurs, all of the transactions in the mempool may be descendants from a transaction which is in the pre-reorg block. This can cause us to propagate updates, worst case, to every transaction in the mempool.
Because we construct a `setEntries setChildren`, which is backed by a `std::set`, it is possible that this algorithm is `O(N log N)`.
By using an Epoch visitor pattern, we can limit this to `O(N)` worst case behavior.
Epochs are also less resource intensive than almost any set option (e.g., hash set) because they are allocation free.
This PR is related to https://github.com/bitcoin/bitcoin/pull/17268, it is a small subset of the changes which have been refactored slightly to ease review. If this PR gets review & merge, I will follow up with more PRs (similar to #17268) to improve the mempool

Pull request description:
This PR builds on #17578 (now merged) and deprecates the rpc getaddressinfo `label` field. The deprecated behavior can be re-enabled by starting bitcoind with `-deprecatedrpc=label`.
See http://www.erisian.com.au/bitcoin-core-dev/log-2019-11-22.html#l-622 and https://github.com/bitcoin/bitcoin/pull/17283#issuecomment-554458001 for more context.
Reviewers: This PR may be tested manually by building, then running bitcoind with and without the `-deprecatedrpc=label` flag while verifying the rpc getaddressinfo output and help text.
Next step: add support for multiple labels.

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.

When a developer is examining `debug.log` after something goes wrong, it's often useful to know the exact options the failing instance of `bitcoind` was started with.

1b96a3cd1ebe725896f59614903184289fe62cf8 tests: reset fIsBareMultisigStd after bare-multisig tests (fanquake)
Pull request description:
Fixes: #18015
The bug this fixes is two-part.
1. The `fIsBareMultisigStd` global is being reused by other tests,
such as [script_p2sh_tests(set)](https://github.com/bitcoin/bitcoin/blob/master/src/test/script_p2sh_tests.cpp#L150), after being set to false.
2. The order our tests run in doesn't always? seem to be random,
which meant that the `script_p2sh` tests would only fail if they
were run in an order where the `transaction_tests` ran first,
mutating the `fIsBareMultisigStd` global.
This doesn't seem to happen when running make check, but if you
run `src/test/test_bitcoin and pass --random=99999`, the failure
in `script_p2sh` will occur (on most, but maybe not all systems):
```bash
src/test/test_bitcoin --random=99999
Running 389 test cases...
test/script_p2sh_tests.cpp:200: error: in "script_p2sh_tests/set": txTo[1].IsStandard

test/script_p2sh_tests.cpp:200: error: in "script_p2sh_tests/set": txTo[3].IsStandard
*** 3 failures are detected in the test module "Bitcoin Core Test Suite"
```
The new test for bare multisig was introduced in #17502.

Pull request description:
Continuation of wallet boxes project.
Actually makes ScriptPubKeyMan an interface which LegacyScriptPubkeyMan. Moves around functions and things from CWallet into LegacyScriptPubKeyMan so that they are actually separate things without circular dependencies.
***
Introducing the `ScriptPubKeyMan` (short for ScriptPubKeyManager) for managing scriptPubKeys and their associated scripts and keys. This functionality is moved over from `CWallet`. Instead, `CWallet` will have a pointer to a `ScriptPubKeyMan` for every possible address type, internal and external. It will fetch the correct `ScriptPubKeyMan` as necessary. When fetching new addresses, it chooses the `ScriptPubKeyMan` based on address type and whether it is change. For signing, it takes the script and asks each `ScriptPubKeyMan` for whether that `ScriptPubKeyMan` considers that script `IsMine`, whether it has that script, or whether it is able to produce a signature for it. If so, the `ScriptPubKeyMan` will provide a `SigningProvider` to the caller which will use that in order to sign.
There is currently one `ScriptPubKeyMan` - the `LegacyScriptPubKeyMan`. Each `CWallet` will have only one `LegacyScriptPubKeyMan` with the pointers for all of the address types and change pointing to this `LegacyScriptPubKeyMan`. It is created when the wallet is loaded and all keys and metadata are loaded into it instead of `CWallet`. The `LegacyScriptPubKeyMan` is primarily made up of all of the key and script management that used to be in `CWallet`. For convenience, `CWallet` has a `GetLegacyScriptPubKeyMan` which will return the `LegacyScriptPubKeyMan` or a `nullptr` if it does not have one (not yet implemented, but callers will check for the `nullptr`). For purposes of signing, `LegacyScriptPubKeyMan`'s `GetSigningProvider` will return itself rather than a separate `SigningProvider`. This will be different for future `ScriptPubKeyMan`s.
The `LegacyScriptPubKeyMan` will also handle the importing and exporting of keys and scripts instead of `CWallet`. As such, a number of RPCs have been limited to work only if a `LegacyScriptPubKeyMan` can be retrieved from the wallet. These RPCs are `sethdseed`, `addmultisigaddress`, `importaddress`, `importprivkey`, `importpubkey`, `importmulti`, `dumpprivkey`, and `dumpwallet`. Other RPCs which relied on the wallet for scripts and keys have been modified in order to take the `SigningProvider` retrieved from the `ScriptPubKeyMan` for a given script.
Overall, these changes should not effect how everything actually works and the user should experience no difference between having this change and not having it. As such, no functional tests were changed, and the only unit tests changed were those that were directly accessing `CWallet` functions that have been removed.
This PR is the last step in the [Wallet Structure Changes](https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Class-Structure-Changes).

The bug this fixes is two-part.
1.The fIsBareMultisigStd global is being reused by other tests,
i.e script_p2sh_tests(set), after being set to false.
2. The order our tests run in doesn't always? seem to be random,
which meant that the script_p2sh tests would only fail if they
were run in an order where transaction_tests ran first, mutating
the fIsBareMultisigStd global.
This doesn't seem to happen when running make check, but if you
run src/test/test_bitcoin and pass --random=99999, the failure
in script_p2sh:
test/script_p2sh_tests.cpp:200: error: in "script_p2sh_tests/set": txTo[1].IsStandard
will occur (on most systems).
The new test was introduced in 1bb5d517aa616c1d5b5801d2ea36a2de5fb61eba.

f41d58966995fe69df433fa684117fae74a56e66 Document better -keypool as a look-ahead safety mechanism (Antoine Riard)
Pull request description:
If after a backup, an address is issued beyond the initial
keypool range and none of the addresses in this range
is seen onchain, if a wallet is restored from backup, even in
case of rescan, funds may be loss due to the look-ahead
buffer not being incremented and so restored wallet not detecting
onchain out-of-range address as derived from its seed.
This scenario is theoretically unavoidable due to the requirement
of the keypool to have a max size. However, given the default
keypool size, this is unlikely. Document better keypool size
implications to avoid user setting a too low value.
While reviewing #17681, it took me a while to figure out the safety implications of keypool, I find it would be better to document this a bit farther to avoid users shooting themselves in the foot. For further context & discussion, see https://github.com/bitcoin/bitcoin/pull/17681#issuecomment-563613452

In order to determine whether to download or process a relayed transaction, we
try to determine if we already have the transaction, either in the mempool, in
our recently rejected filter, in our orphan pool, or already confirmed in the
chain itself.
Prior to this commit, the heuristic for checking the chain is based on whether
there's an output corresponding to the 0- or 1-index vout in our coin cache.
While that is a quick check, it is very imprecise (say if those outputs were
already spent in a block) -- we can do better by just keeping a rolling bloom
filter of the transactions in recent blocks, which will capture the case of a
transaction which has been confirmed and then fully spent already.
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.

b6c3e84e87055be311347d7b636d68a6a828f563 doc: Improve fuzzing docs for macOS users (Fabian Jahr)
Pull request description:
Adds several helpful hints for macOS users trying to get fuzzers to run locally using AFL or libFuzzer. These are partly based on this comment https://github.com/bitcoin/bitcoin/issues/17657#issuecomment-562869600 and discussions in the review club for #17860. See: https://bitcoincore.reviews/17860.html
Based on the doc in the current state I could not compile fuzzers for AFL or libFuzzer. Using these hints, I can
- compile and run fuzzers with AFL
- compile but **not** run fuzzers with libFuzzer
Fuzzers compiled with libFuzzers may be running but don't produce any output. Looking for others to test this to see if it is an issue with my local system. Especially interesting if you have been running libFuzzer fuzzers successfully on macOS before.
Edit: Closes #17914

8feb4e4b667361bf23344149c01594abebd56fdb Add asmap utility which queries a mapping (Gleb Naumenko)
Pull request description:
This PR attempts to solve the problem explained in #16599.
A particular attack which encouraged us to work on this issue is explained here [[Erebus Attack against Bitcoin Peer-to-Peer Network](https://erebus-attack.comp.nus.edu.sg/)] (by @muoitranduc)
Instead of relying on /16 prefix to diversify the connections every node creates, we would instead rely on the (ip -> ASN) mapping, if this mapping is provided.
A .map file can be created by every user independently based on a router dump, or provided along with the Bitcoin release. Currently we use the python scripts written by @sipa to create a .map file, which is no larger than 2MB (awesome!).
Here I suggest adding a field to peers.dat which would represent a hash of asmap file used while serializing addrman (or 0 for /16 prefix legacy approach).
In this case, every time the file is updated (or grouping method changed), all buckets will be re-computed.
I believe that alternative selective re-bucketing for only updated ranges would require substantial changes.
TODO:
- ~~more unit tests~~
- ~~find a way to test the code without including >1 MB mapping file in the repo.~~
- find a way to check that mapping file is not corrupted (checksum?)
- comments and separate tests for asmap.cpp
- make python code for .map generation public
- figure out asmap distribution (?)
~Interesting corner case: I’m using std::hash to compute a fingerprint of asmap, and std::hash returns size_t. I guess if a user updates the OS to 64-bit, then the hash of asap will change? Does it even matter?~

b35567fe0ba3e6f8d8f9525088eb8ee62065ad01 test: only declare a main() when fuzzing with AFL (fanquake)
Pull request description:
This fixes fuzzing using [libFuzzer](https://llvm.org/docs/LibFuzzer.html) on macOS, which caused a few issues during the recent review club. macOS users could only fuzz using afl, or inside a VM.
It seems that the `__attribute__((weak))` marking is not quite enough to properly mark `main()` as weak on macOS. See Apples docs on [Frameworks and Weak Linking](https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html#//apple_ref/doc/uid/20002378-107262-CJBJAEID).

Pull request description:
Fixes #17149
Two classes of issues were found by the psbt fuzzer: values out of range and causing overflows, and prevout indexes being out of range. This PR fixes both.
When accessing a specific output using the index given in the tx, check that it is actually a possible output before trying to access the output.
When summing and checking amounts for `decodepsbt` and `analyzepsbt`, make sure that the values are actually valid money values.. Otherwise, stop summing and don't show the fee. For `analyzepsbt`, return that the next role is the Creator since the Creator needs to remake the transaction to be valid.

e6050884fdabfa6e51e6afce2041d91e60a5adec guix: Pin Guix using `guix time-machine` (Carl Dong)
Pull request description:
An alternative to #16519, pinning our version of Guix and eliminating a `guix pull` and changing the default Guix profile of builders.
I think this method might be superior, as it:
- Eliminates the possibility of future changes to the `guix environment` command line interface breaking our builds
- Eliminates the need to set up a separate channel repo
It is a more general pinning solution than #16519.
-----
The reason why I didn't originally propose this is because `guix time-machine` is a recent addition to Guix, only available since `f675f8dec73d02e319e607559ed2316c299ae8c7`
