cdd51e8ee156f3bb3135be8aa51530a53734153e torcontrol: Resolve Tor control plane address (Adrian-Stefan Mares)
Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/22236
This PR forces the Tor control plane address to be resolved before a connection attempt is made, similar to how the `-proxy` / `-onion` address is resolved.
The use case for this change is that the control plane may not have a stable address - in a containerized environment perhaps.

090b75c14be6b9ba2efe38a17d141c6e6af575cb p2p: Avoid allocating memory for addrKnown where we don't need it (User)
Pull request description:
We should allocate memory for addrKnown filter only for those peers which are expected to participate in address relay.
Currently, we do it for all peers (including SPV and block-relay-only), which results in extra RAM where it's not needed.
Upd:
In future, we would still allow SPVs to ask for addrs, so allocation still will be done by default.
However, they will be able to opt-out via [this proposal](https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2019-October/017428.html) and then we could save some more memory.
This PR still saves memory for block-relay-only peers immediately after merging.

eadd1304c81e0b89178e4cc7630bd31650850c85 tests: Add a test for funding with sufficient preset inputs and subtractFeeFromOutputs (Andrew Chow)
ff330badd45067cb520b1cfa1844f60a4c9f2031 Default to bnb_used = false as there are many cases where BnB is not used (Andrew Chow)
Pull request description:
#17290 introduced a bug where, when we had preset inputs that covered the amount being sent and subtractFeeFrromOutputs was being used, transaction funding would result in a `Fee exceeds maximum configured by -maxtxfee` error. This was happening because we weren't setting `bnb_used = false` when the preset inputs were used as it should have been. This resulted in a too high fee because the change would go to fees accidentally.
Apparently this particular case doesn't have a test, so I've added one as well.

Currently we explicitly disable BnB when there are preset inputs selected or when the subtract fee from outputs option is enabled. This PR enables BnB for both cases.

70cda342cd20d0e0cd9f28405457544036968f2d rpc: improve getaddressinfo RPCHelpman formatting (Jon Atack)
Pull request description:
This PR is a continuation of the work in https://github.com/bitcoin/bitcoin/pull/12892.
Main motivations:
- There is currently no test coverage for the getaddressinfo `labels` response. Coverage here is a prerequisite before deprecating the `label` response or adding multiple labels per address.
- `bitcoin-cli help getaddressinfo` returns a few content errors, difficult-to-read formatting, and no explanation why it returns both `label` and `labels` and how they relate, which can be confusing for application developers.
Changes by order of commits:
- [x] improve/fix getaddressinfo RPCHelpman layout formatting
- [x] improve/fix getaddressinfo RPCHelpman content
- [x] clarify the `label` and `labels` fields in getaddressinfo RPCHelpman
- [x] update getaddressinfo RPCExamples addresses to bech32
- [x] add getaddressinfo code docs
- [x] add a `listlabels` test assertion in wallet_labels.py
- [x] add missing getaddressinfo `labels` test coverage and improve the existing `label` tests
Here are gists of the CLI help output:
[`bitcoin-cli help getaddressinfo` before this PR](https://gist.github.com/jonatack/022af5221a85c069780359a22643c810)
[`bitcoin-cli help getaddressinfo` after this PR](https://gist.github.com/jonatack/4ee5f6abc62a3d99269570206a5f90ba)
It seems we ought to begin a deprecation process for the getaddressinfo `label` field? If yes, I have a follow-up ready. _--> EDIT: Deprecation follow-ups #17578 and #17585 now build on this PR._

Please provide clear motivation for your patch and explain how it improves
Bitcoin Core user experience or Bitcoin Core developer experience
significantly:
* Any test improvements or new tests that improve coverage are always welcome.
* All other changes should have accompanying unit tests (see `src/test/`) or
functional tests (see `test/`). Contributors should note which tests cover
modified code. If no tests exist for a region of modified code, new tests
should accompany the change.
* Bug fixes are most welcome when they come with steps to reproduce or an
explanation of the potential issue as well as reasoning for the way the bug
was fixed.
* Features are welcome, but might be rejected due to design or scope issues.
If a feature is based on a lot of dependencies, contributors should first
consider building the system outside of Bitcoin Core, if possible.
* Refactoring changes are only accepted if they are required for a feature or
bug fix or otherwise improve developer experience significantly. For example,
most "code style" refactoring changes require a thorough explanation why they
are useful, what downsides they have and why they *significantly* improve
developer experience or avoid serious programming bugs. Note that code style
is often a subjective matter. Unless they are explicitly mentioned to be
preferred in the [developer notes](/doc/developer-notes.md), stylistic code
changes are usually rejected.

<!--
Bitcoin Core has a thorough review process and even the most trivial change
needs to pass a lot of eyes and requires non-zero or even substantial time
effort to review. There is a huge lack of active reviewers on the project, so
patches often sit for a long time.

dce032ce294fe0d531770f540b1de00dc1d13f4b Make IsTrusted scan parents recursively (Jeremy Rubin)
Pull request description:
This slightly modifies the behavior of IsTrusted to recursively check the parents of a transaction. Otherwise, it's possible that a parent is not IsTrusted but a child is. If a parent is not trusted, then a child should not be either.
This recursive scan can be a little expensive, so ~it might be beneficial to have a way of caching IsTrusted state, but this is a little complex because various conditions can change between calls to IsTrusted (e.g., re-org).~ I added a cache which works per call/across calls, but does not store the results semi-permanently. Which reduces DoS risk of this change. There is no risk of untrusted parents causing a resource exploitation, as we immediately return once that is detected.
This is a change that came up as a bug-fix esque change while working on OP_SECURETHEBAG. You can see the branch where this change is important here: https://github.com/bitcoin/bitcoin/compare/master...JeremyRubin:stb-with-rpc?expand=1. Essentially, without this change, we can be tricked into accepting an OP_SECURETHEBAG output because we don't properly check the parents. As this was a change which, on its own, was not dependent on OP_SECURETHEBAG, I broke it out as I felt the change stands on its own by fixing a long standing wallet bug.
The test wallet_balance.py has been corrected to meet the new behavior. The below comment, reproduced, explains what the issue is and the edge cases that can arise before this change.
# Before `test_balance()`, we have had two nodes with a balance of 50
# each and then we:
#
# 1) Sent 40 from node A to node B with fee 0.01
# 2) Sent 60 from node B to node A with fee 0.01
#
# Then we check the balances:
#
# 1) As is
# 2) With transaction 2 from above with 2x the fee
#
# Prior to #16766, in this situation, the node would immediately report
# a balance of 30 on node B as unconfirmed and trusted.
#
# After #16766, we show that balance as unconfirmed.
#
# The balance is indeed "trusted" and "confirmed" insofar as removing
# the mempool transactions would return at least that much money. But
# the algorithm after #16766 marks it as unconfirmed because the 'taint'
# tracking of transaction trust for summing balances doesn't consider
# which inputs belong to a user. In this case, the change output in
# question could be "destroyed" by replace the 1st transaction above.
#
# The post #16766 behavior is correct; we shouldn't be treating those
# funds as confirmed. If you want to rely on that specific UTXO existing
# which has given you that balance, you cannot, as a third party
# spending the other input would destroy that unconfirmed.
#
# For example, if the test transactions were:
#
# 1) Sent 40 from node A to node B with fee 0.01
# 2) Sent 10 from node B to node A with fee 0.01
#
# Then our node would report a confirmed balance of 40 + 50 - 10 = 80
# BTC, which is more than would be available if transaction 1 were
# replaced.
The release notes have been updated to note the new behavior.

Pull request description:
This is a "refactor" that shouldn't change behaviour, because the two times are most likely equal. A minimum of 5 outbound peers are needed to adjust the time. And if the time is adjusted, it will be by at most 70 minutes (`DEFAULT_MAX_TIME_ADJUSTMENT`). Thus, the progress estimate should differ by at most 7 blocks.

* `m_best_block_time` is set to the "unadjusted" time, thus a comparison of the two times is like comparing apples to oranges. In the worst case this opens up an attack vector where remote peers can force a premature re-broadcast of wallet txs.
* The RPC documentation for `"timereceived"` doesn't mention that the network adjusted time is used, possibly confusing users when the time reported by RPC is off by a few seconds compared to their local timestamp.
Fix all issues by replacing the call with `GetTime()`. Also a style fix: Use non-narrowing integer conversion in the RPC method.

fa165e954579436fe4b636e4222d8ce0c1269786 Replace stoul with ToIntegral in dbwrapper (MarcoFalke)
Pull request description:
The string is created with `%llu`. See: 7fcf53f7b4/src/leveldb/db/db_impl.cc (L1436-L1437)
So it seems odd to silently accept when parsing: whitespace, a sign character, trailing chars, overflow, ....
Fix that by using the stricter ToIntegral.

73b96c94cb6c2afdee7f151768a96944ecaf9d9b net: Fix uninitialized read in ProcessMessage(...) (practicalswift)
Pull request description:
Fix an uninitialized read in `ProcessMessage(…, "tx", …)` when receiving a transaction we already have.
The uninitialized value is read and used on [L2526 in the case of `AlreadyHave(inv) == true`](d8a66626d6/src/net_processing.cpp (L2494-L2526)).
Proof of concept being run against a `bitcoind` built with MemorySanitizer (`-fsanitize=memory`):
```
$ ./p2p-uninit-read-in-conditional-poc.py
Usage: ./p2p-uninit-read-in-conditional-poc.py <dstaddr> <dstport> <net>
$ bitcoind -regtest &
$ ./p2p-uninit-read-in-conditional-poc.py 127.0.0.1 18444 regtest
SUMMARY: MemorySanitizer: use-of-uninitialized-value
[1]+ Exit 77 bitcoind -regtest
$
```
Proof of concept being run against a `bitcoind` running under Valgrind (`valgrind --exit-on-first-error`):
```
$ valgrind -q --exit-on-first-error=yes --error-exitcode=1 bitcoind -regtest &
$ ./p2p-uninit-read-in-conditional-poc.py 127.0.0.1 18444 regtest
==27351== Conditional jump or move depends on uninitialised value(s)
[1]+ Exit 1 valgrind -q --exit-on-first-error=yes --error-exitcode=1 bitcoind -regtest
$
```
Proof of concept script:
```
#!/usr/bin/env python3
import sys
from test_framework.mininode import NetworkThread
from test_framework.mininode import P2PDataStore
from test_framework.messages import CTransaction, CTxIn, CTxOut, msg_tx
def send_duplicate_tx(dstaddr="127.0.0.1", dstport=18444, net="regtest"):
network_thread = NetworkThread()
network_thread.start()
node = P2PDataStore()
node.peer_connect(dstaddr=dstaddr, dstport=dstport, net=net)()
node.wait_for_verack()
tx = CTransaction()
tx.vin.append(CTxIn())
tx.vout.append(CTxOut())
node.send_message(msg_tx(tx))
node.send_message(msg_tx(tx))
node.peer_disconnect()
network_thread.close()
if __name__ == "__main__":
if len(sys.argv) != 4:
print("Usage: {} <dstaddr> <dstport> <net>".format(sys.argv[0]))
sys.exit(0)
send_duplicate_tx(sys.argv[1], int(sys.argv[2]), sys.argv[3])
```
Note that the transaction in the proof of concept is the simplest possible, but really any transaction can be used. It does not have to be a valid transaction.
This bug was introduced in #15921 ("validation: Tidy up ValidationState interface") which was merged in to `master` 28 days ago.
Luckily this bug was caught before being part of any Bitcoin Core release :)

Pull request description:
Carries out some remaining tidy-ups remaining after PR 15141:
- split ValidationState into TxValidationState and BlockValidationState (commit from ajtowns)
- various minor code style tidy-ups to the ValidationState class
- remove the useless `ret` parameter from `ValidationState::Invalid()`
- remove the now unused `first_invalid` parameter from `ProcessNewBlockHeaders()`
- remove the `fMissingInputs` parameter from `AcceptToMemoryPool()`, and deal with missing inputs the same way as other errors by using the `TxValidationState` object.
Tip for reviewers (thanks ryanofsky!): The first commit ("[validation] Add CValidationState subclasses" ) is huge and can be easier to start reviewing if you revert the rote, mechanical changes:
Substitute the commit hash of commit "[validation] Add CValidationState subclasses" for <CommitHash> in the commands below.
```sh
git checkout <CommitHash>
git grep -l ValidationState | xargs sed -i 's/BlockValidationState\|TxValidationState/CValidationState/g'
git grep -l ValidationResult | xargs sed -i 's/BlockValidationResult\|TxValidationResult/ValidationInvalidReason/g'
git grep -l MaybePunish | xargs sed -i 's/MaybePunishNode\(ForBlock\|ForTx\)/MaybePunishNode/g'
git diff HEAD^
```
After that it's possible to easily see the mechanical changes with:
```sh
git log -p -n1 -U0 --word-diff-regex=. <CommitHash>
```

Pull request description:
We no longer send BIP 61 REJECT messages, so there's no need to set
a REJECT code in the CValidationState object.
Note that there is a minor bug fix in p2p behaviour here. Because the
call to `MaybePunishNode()` in `PeerLogicValidation::BlockChecked()` only
previously happened if the REJECT code was > 0 and < `REJECT_INTERNAL`,
then there are cases were `MaybePunishNode()` can get called where it
wasn't previously:
- when `AcceptBlockHeader()` fails with `CACHED_INVALID`.
- when `AcceptBlockHeader()` fails with `BLOCK_MISSING_PREV`.
Note that `BlockChecked()` cannot fail with an 'internal' reject code. The
only internal reject code was `REJECT_HIGHFEE`, which was only set in
ATMP.
This reverts a minor bug introduced in 5d08c9c579.

Noticed that there wasn't a default value for the send amount. However if you put a value in or click the up and down arrows you're unable to get it blank again, so it makes sense that it has a default value. I hope this also makes it more clear that users can send less than 1 BTC if it shows the 8 decimal places

e65e61c812df90a56e3ce4a8e76c4b746766f387 Add some general std::vector utility functions (Pieter Wuille)
Pull request description:
This is another general improvement extracted from #16800 .
Two functions are added are:
* Vector(arg1,arg2,arg3,...) constructs a vector with the specified arguments as elements. The vector's type is derived from the arguments. If some of the arguments are rvalue references, they will be moved into place rather than copied (which can't be achieved using list initialization).
* Cat(vector1,vector2) returns a concatenation of the two vectors, efficiently moving elements when relevant.
Vector generalizes (and replaces) the `Singleton` function in src/descriptor.cpp, and `Cat` replaces the function in bech32.cpp

ea4cc3a7b36a9c77dbf0aff439da3ef0ea58e6e4 Truly decouple wallet from chainparams for -fallbackfee (Jorge Timón)
Pull request description:
Before it was 0 by default for main and 20000 for test and regtest.
Now it is 0 by default for all chains, thus there's no need to call Params().
Also now the default for main is properly documented.
Suggestion for release notes:
-fallbackfee was 0 (disabled) by default for the main chain, but 20000 by default for the test chains. Now it is 0 by default for all chains. Testnet and regtest users will have to add fallbackfee=20000 to their configuration if they weren't setting it and they want it to keep working like before.
Should I propose them to the wiki for the release notes or only after merge?

5c5d0b62648e1b144b7b93c199f45265dac100e5 Add FoundBlock.found member (Russell Yanofsky)
Pull request description:
This change lets IPC serialization code handle FoundBlock arguments more simply and efficiently. Without this change there was no way to determine from a FoundBlock object whether a block was found or not. So in order to correctly implement behavior of leaving FoundBlock output variables unmodified when a block was not found, IPC code would have to read preexisting output variable values from the local process, send them to the remote process, receive output values back from the remote process, and save them to output variables unconditionally. With FoundBlock.found method, the process is simpler. There's no need to read or send preexisting local output variable values, just to read final output values from the remote process and set them conditionally if the block was found.

Pull request description:
Without a size limit on the input data, the runtime is unbounded. Fix this by picking an upper bound on the maximum number of fuzz operations.

.PHONY does not take patterns (such as print-%) as prerequisites.
Have print-% depend on force and mark force as phony.
This change ensures print-% rule works even when there is a file that matches the target.

which I took straight from the PSBT test vectors. The reason is that in src/psbt.h we call `DeserializeHDKeypaths`, which in turn calls `CPubKey::IsFullyValid`, which in turn asserts that a secp context has been created.
The error appears to be masked on many systems by the definition of `instance_of_eccryptoclosure` in src/script/bitcoinconsensus.cpp, which defines a static object which contains an `ECCVerifyHandle`. If you just comment out that line you can reliably trigger the fuzz test failure, e.g. by creating a file `crash` with the above PSBT, and runnnig

This PR is a (quite late) follow-up to #19237 (https://github.com/bitcoin/bitcoin/pull/19237#issuecomment-642203251). Looking at `CPubKey::Serialize` and `CPubKey::Unserialize` I can't think of a scenario where the roundtrip (serialization/deserialization) equality wouldn't hold.

d44a261acff40c1c8727d3cc0106bde65a6416d0 Fix issues when `walletdir` is root directory (unknown)
Pull request description:
+ Remove one character less from wallet path
+ After testing lot of random strings with special chars in `wallet_name`, I found that the issue was not related to special characters in the name. Reviewing PR https://github.com/bitcoin/bitcoin/pull/21907 helped me resolve the issue.
**Real issue**: If the path mentioned in `walletdir` is a root directory, first character of the wallet name or path is removed
**Solution**: `if` statement to check `walletdir` is a root directory
Fixes: https://github.com/bitcoin/bitcoin/issues/21510https://github.com/bitcoin/bitcoin/issues/21501
Related PR: https://github.com/bitcoin/bitcoin/pull/20080
Consider the wallet directories `w1` and `w2` saved in `D:\`. Run `bitcoind.exe -walletdir=D:\`, Results for `bitcoin-cli.exe listwalletdir`:
Before this PR:
```

"wallets": [
{
"name": "1"

After this PR:

1be6267ce1ee142c3b90baed1925a82eab6514aa fuzz: don't try and use fopencookie when building for Android (fanquake)
Pull request description:
When building for Android, `_GNU_SOURCE` will be defined:
```bash
/home/ubuntu/android-sdk/ndk/22.1.7171670/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android30-clang++ -dM -E -x c++ - < /dev/null

#define __AARCH64_CMODEL_SMALL__ 1
#define __ANDROID_API__ 30

#define __ARM_64BIT_STATE 1
.....
```
but it doesn't have the [`fopencookie()` function](https://www.gnu.org/software/libc/manual/html_node/Streams-and-Cookies.html), or define the `cookie_io_functions_t` type, which results in compile failures:
```bash
In file included from test/fuzz/addition_overflow.cpp:7:
./test/fuzz/util.h:388:15: error: unknown type name 'cookie_io_functions_t'
const cookie_io_functions_t io_hooks = {
^
15 warnings and 1 error generated.
```
Just skip trying to use it if we are building for Android. Should fix#22062.

5e146022daa4336de94447e5b8e5418296286927 wallet: fix scanning progress calculation for single block range (Sebastian Falbesoner)
Pull request description:
If the blockchain is rescanned for a single block (i.e. start and stop hashes are equal, and with that also the estimated start/stop verification progress values) the progress calculation could lead to a NaN value caused by a division by zero (0.0/0.0), resulting in an invalid JSON result for the `getwalletinfo` RPC. This PR fixes this behaviour by setting the progress to zero in that special case. Fixes#20297.
The behaviour can easily be reproduced by continuously running single block rescans in an endless loop, e.g. via
```bash
#!/bin/bash
while true
do
bitcoin-cli rescanblockchain $(bitcoin-cli getblockcount)
done
```
and at the same time perform some `getwalletinfo` RPCs.
On the master branch, this leads to frequent invalid responses (tested on mainchain):
```
$ bitcoin-cli getwalletinfo
error: couldn't parse reply from server
$ curl --user `cat ~/.bitcoin/.cookie` --data-binary '{"jsonrpc": "1.0", "id": "curltest", "method": "getwalletinfo", "params": []}' -H 'content-type: text/plain;' http://127.0.0.1:8332/
{"result":{"walletname":"","walletversion":169900,"format":"bdb","balance":0.00000000,"unconfirmed_balance":0.00000000,"immature_balance":0.00000000,"txcount":0,"keypoololdest":1603677276,"keypoolsize":1000,"hdseedid":"3196e33ecb47c7130e6ca60f2f895f9259860dca","keypoolsize_hd_internal":1000,"paytxfee":0.00000000,"private_keys_enabled":true,"avoid_reuse":false,"scanning":{"duration":0,"progress":},"descriptors":false},"error":null,"id":"curltest"}
```
(note that missing value for "progress" in the JSON result).
On the PR branch, the behaviour doesn't occur anymore.
