faafc35a77 doc: Clarify that -datacarriersize applies to the full raw scriptPubKey, not the data push (MarcoFalke)
55550e7fe7 test: Add -datacarriersize=2 tests (MarcoFalke)
Pull request description:
Clarify with a test that `-datacarriersize` applies to the serialized size of the scriptPubKey, not the size of the pushed data. So for example,
* `-datacarriersize=2` will reject a `raw(6a01aa)`, even though only one byte is pushed
* `-datacarriersize=0` (or `-datacarrier=0`) will reject a `raw(6a)`, even though no byte is pushed
* `-datacarriersize=0` (or `-datacarrier=0`) will reject a `raw(6a00)`, even though zero bytes are pushed

025fda0a76 fuzz: addrman, avoid `ConsumeDeserializable` when possible (brunoerg)
Pull request description:
Using specific functions like `ConsumeService`, `ConsumeAddress` and `ConsumeNetAddr` may be more effective than using `ConsumeDeserializable`. They always return some value while `ConsumeDeserializable` may return `std::nullopt`.
E.g.: In this part of the code, if `op_net_addr` is `std::nullopt`, we basically generated the addresses (if so) unnecessarily, because we won't be able to use them:
```cpp
std::vector<CAddress> addresses;
LIMITED_WHILE(fuzzed_data_provider.ConsumeBool(), 10000) {
const std::optional<CAddress> opt_address = ConsumeDeserializable<CAddress>(fuzzed_data_provider);
if (!opt_address) {
break;
}
addresses.push_back(*opt_address);
}
const std::optional<CNetAddr> opt_net_addr = ConsumeDeserializable<CNetAddr>(fuzzed_data_provider);
if (opt_net_addr) {
addr_man.Add(addresses, *opt_net_addr, std::chrono::seconds{ConsumeTime(fuzzed_data_provider, 0, 100000000)});
}
```
Also, if we are not calling `Add` effectively, it would also be affect other functions that may "depend" on it.

Pull request description:
Closes https://github.com/bitcoin/bitcoin/issues/27140
Adds test coverage for https://github.com/bitcoin/bitcoin/pull/20516 to ensure that https://github.com/bitcoin/bitcoin/issues/20511 is completed and may be closed.
This PR adds a test case to `feature_anchors.py` where an onion v3 address is set as a blocks-only relay peer and then shutdown, ensuring that the address is saved to anchors.dat in addrv2 format. We then ensure that bitcoin attempts to reconnect to that anchor address on restart.
To compute the addrv2 serialization of the onion v3 address, I added logic to `CAddress` in `messages.py`. This new logic is covered by extending `p2p_addrv2_relay.py` to include an onion v3 address. Future work will be adding coverage for ipv6, torv2 and cjdns in these modules and also `feature_proxy.py`
Also includes de/serialization unit test for `CAddress` in test framework.

2c0c6f4477 test: dedup file hashing using `sha256sum_file` helper (Sebastian Falbesoner)
Pull request description:
Rather than doing the open/read/hash-steps manually in the affected functional tests, we can just use the `sha256sum_file` helper from the utils module instead.
Note that for the tool_wallet.py test, the used hash is changed from sha1 to sha256, but as the only purpose is to detect file content changes, this doesn't matter. Also, the optimization using `memoryview` is overkill here, as the opened file has only a size of 24KiB and determining the hash via the helper doesn't take longer than a few hundred micro-seconds on my machine.

Pull request description:

In the consistency check, it's not enough to check that our address/port is unique, only the combination of source and target must be unique. Otherwise, the OS may reuse ports for connections to different `-addrbind`, which was happening in the failed runs.
While at it, the second commit cleans up duplicate `getaddr` messages in `p2p_getaddr_caching.py` that do nothing but generate `Ignoring repeated "getaddr"` log messages (and cleans up some whitespace the python linter complains about).

Pull request description:
This PR proposes a clean up of the relationship between block storage and the chainstate objects, by moving the decision of whether to store a block on disk to something that is not chainstate-specific. Philosophically, the decision of whether to store a block on disk is related to validation rules that do not require any UTXO state; for anti-DoS reasons we were using some chainstate-specific heuristics, and those have been reworked here to achieve the proposed separation.
This PR also fixes a bug in how a chainstate's `setBlockIndexCandidates` was being initialized; it should always have all the HAVE_DATA block index entries that have more work than the chain tip. During startup, we were not fully populating `setBlockIndexCandidates` in some scenarios involving multiple chainstates.
Further, this PR establishes a concept that whenever we have 2 chainstates, that we always know the snapshotted chain's base block and the base block's hash must be an element of our block index. Given that, we can establish a new invariant that the background validation chainstate only needs to consider blocks leading to that snapshotted block entry as potential candidates for its tip. As a followup I would imagine that when writing net_processing logic to download blocks for the background chainstate, that we would use this concept to only download blocks towards the snapshotted entry as well.

131314b62e fuzz: increase coverage of the descriptor targets (Antoine Poinsot)
90a24741e7 fuzz: add a new, more efficient, descriptor parsing target (Antoine Poinsot)
d60229ede5 fuzz: make the parsed descriptor testing into a function (Antoine Poinsot)
Pull request description:
The current descriptor parsing fuzz target requires valid public or private keys to be provided. This is unnecessary as we are only interested in fuzzing the descriptor parsing logic here (other targets are focused on fuzzing keys serializations). And it's pretty inefficient, especially for formats that need a checksum (`xpub`, `xprv`, WIF).
This introduces a new target that mocks the keys as an index in a list of precomputed keys. Keys are represented as 2 hex characters in the descriptor. The key type (private, public, extended, ..) is deterministically based on this one-byte value. Keys are deterministically generated at target initialization. This is much more efficient and also largely reduces the size of the seeds.
TL;DR: for instance instead of requiring the fuzzer to generate a `pk(xpub6DdBu7pBoyf7RjnUVhg8y6LFCfca2QAGJ39FcsgXM52Pg7eejUHLBJn4gNMey5dacyt4AjvKzdTQiuLfRdK8rSzyqZPJmNAcYZ9kVVEz4kj)` to parse a valid descriptor, it just needs to generate a `pk(03)`.
Note we only mock the keys themselves, not the entire descriptor key expression. As we want to fuzz the real code that parses the rest of the key expression (origin, derivation paths, ..).
This is a target i used for reviewing #17190 and #27255, and figured it was worth PR'ing on its own since the added complexity for mocking the keys is minimal and it could help prevent introducing bugs to the descriptor parsing logic much more efficiently.

0fc3deee9a test: remove unecessary `decoderawtransaction` calls (brunoerg)
Pull request description:
This PR removes in `wallet_fundrawtransaction`:
- unecessary variables/calls to `decoderawtransaction`
- unused `totalOut` variable and its related code (`totalOut` is used in some functions to test change, in other ones its value is not used)

08eb5f1b67 ci: document that -Wreturn-type has been fixed upstream (Windows) (fanquake)
Pull request description:
`noreturn` attributes have been added to the mingw-w64 headers, 1690994f51, meaning that [from 11.0.0 onwards](https://www.mingw-w64.org/changelog/), you'll no-longer see `-Wreturn-type` warnings when using `assert(false)`.
Add -Wno-return-type to the Windows CI, where is should have been all
along, and document why it's required. This can be dropped when we are
using the fixed version of the mingw-w64 headers there.
Drop the -Werror -Wno-return-type special case from our build system.
-Wreturn-type is on by default in Clang and GCC.
The new mingw-w64 header behaviour can be checked on Ubuntu mantic, [which ships with 11.0.0](https://packages.ubuntu.com/mantic/mingw-w64), using:
```cpp
#include <cassert>
int f(){ assert(false); }
int main() {
return 0;
}
```
On Mantic (with 11.0.0):
```bash
x86_64-w64-mingw32-g++ test.cpp -Wreturn-type
# nada
```
On Lunar ([with 10.0.0](https://packages.ubuntu.com/lunar/mingw-w64)):
```bash
x86_64-w64-mingw32-g++ test.cpp -Wreturn-type
test.cpp: In function 'int f()':
test.cpp:3:25: warning: no return statement in function returning non-void [-Wreturn-type]
3 | int f(){ assert(false); }

This check is already done by the rpc parser. Re-doing it is adding dead
code. Instead, throwing an exception when the assumption does not hold
is the already correct behavior.
To make the fuzz test more accurate and not swallow all runtime errors,
add a check that the passed in UniValue sighash argument is either a
string or null.

In `wallet_fundrawtransaction`, `totalOut` is used in
some functions to check if the change is correct. In
other ones, it has been created but never used.
fa9108f85a refactor: Use reinterpret_cast where appropriate (MarcoFalke)
3333f950d4 refactor: Avoid casting away constness (MarcoFalke)
fa6394dd10 refactor: Remove unused C-style casts (MarcoFalke)
Pull request description:
Using a C-style cast to convert pointer types to a byte-like pointer type has many issues:
* It may accidentally and silently throw away `const`.
* It forces reviewers to check that it doesn't accidentally throw away `const`.
For example, on current master a `const char*` is cast to `unsigned char*` (without `const`), see d23fda0584/src/span.h (L273) . This can lead to UB, and the only reason why it didn't lead to UB is because the return type added back the `const`. (Obviously this would break if the return type was deduced via `auto`)
Fix all issues by adding back the `const` and using `reinterpret_cast` where appropriate.

c648bdbda2 test: create wallet specific for test_locked_wallet case (furszy)
Pull request description:
Coming from https://github.com/bitcoin/bitcoin/pull/28089#discussion_r1265478128.
Several test cases are relying on the node1 default wallet, which thanks to 'test_locked_wallet' is encrypted.
And can be only accessed within a specific timeframe (100ms), a duration internally set by the same test.
This situation introduces a potential race condition, where other tests must complete their operations within
the specified 100ms window to pass (otherwise the wallet gets re-locked and they fail).
This can be seen running the test in valgrind (https://github.com/bitcoin/bitcoin/pull/28089), where other test cases fail due the wallet re-locking
itself after the 100ms.

faca9a3d5a test: Avoid intermittent issues due to async events in validationinterface_tests (MarcoFalke)
Pull request description:
Currently the tests have many issues:
* They setup the genesis block, even though it is not needed
* They queue an async `UpdatedBlockTip` even, which causes intermittent issues: https://github.com/bitcoin/bitcoin/issues/28146#issuecomment-1650064645
Fix all issues by trimming down the setup to just `ChainTestingSetup`.

53c990ad34 test: fix `feature_addrman.py` on big-endian systems (Sebastian Falbesoner)
Pull request description:
The test `feature_addrman.py` currently serializes the addrdb without specifying endianness for `int`s, so the machine's native byte order is used (see https://docs.python.org/3/library/struct.html#byte-order-size-and-alignment) and the generated `peers.dat` would be invalid on big-endian systems (our internal (de)serializers always use little-endian, see `ser_{read,write}data32`). Fix this by explicitly specifying little-endian serialization via the `<` character in `struct.pack(...)`.
This is not detected by CI as we unfortunately don't run functional tests on big-endian systems there (I think we definitely should!).

07c59eda00 Don't derive secure_allocator from std::allocator (Casey Carter)
Pull request description:
Giving the C++ Standard Committee control of the public interface of your type means they will break it. C++23 adds a new `allocate_at_least` member to `std::allocator`. Very bad things happen when, say, `std::vector` uses `allocate_at_least` from `secure_allocator`'s base to allocate memory which it then tries to free with `secure_allocator::deallocate`.
(Discovered by microsoft/STL#3712, which will be reverted by microsoft/STL#3819 before it ships.)
