214d9055ac fuzz: replace every fuzzer-controlled loop with a LIMITED_WHILE loop
Blindly chose a cap of 10000 iterations for every loop, except for
the two in script_ops.cpp and scriptnum_ops.cpp which appeared to
(sometimes) be deserializing individual bytes; capped those to one
million to ensure that sometimes we try working with massive scripts.

There was also one fuzzer-controlled loop in timedata.cpp which was
already capped, so I left that alone.

git grep 'while (fuzz' should now run clean except for timedata.cpp

2478c6730a Make signing follow BIP340 exactly w.r.t. aux randomness
libsecp256k1's secp256k1_schnorrsig_sign only follows BIP340 exactly
if an aux_rand32 argument is passed. When no randomness is used
(as is the case in the current codebase here), there is no impact
on security between not providing aux_rand32 at all, or providing
an empty one. Yet, for repeatability/testability it is simpler
to always use an all-zero one.

Pull request description:

  This takes over #21859, which has [recently switched](https://github.com/bitcoin/bitcoin/pull/21859#issuecomment-921899200) to my integration branch. A few more build issues came up (and have been fixed) since, and after discussing with sipa it was decided I would open a PR to shepherd any final changes through.

  > This adds a `src/minisketch` subtree, taken from the master branch of https://github.com/sipa/minisketch, to prepare for Erlay implementation (see #21515). It gets configured for just supporting 32-bit fields (the only ones we're interested in in the context of Erlay), and some code on top is added:
  > * A very basic unit test (just to make sure compilation & running works; actual correctness checking is done through minisketch's own tests).
  > * A wrapper in `minisketchwrapper.{cpp,h}` that runs a benchmark to determine which field implementation to use.

  Only changes since my last update to the branch in the previous PR have been rebasing on master and fixing an issue with a header in an introduced file.

Pull request description:

  Similarly to how #18698 added `ProcessNewBlock()` and `ProcessNewBlockHeaders()` methods to the `ChainstateManager` class, this PR adds a new `ProcessTransaction()` method. Code outside validation no longer calls `AcceptToMemoryPool()` directly, but calls through the higher-level `ProcessTransaction()` method. Advantages:

  - The interface is simplified. Calling code no longer needs to know about the active chainstate or mempool object, since `AcceptToMemoryPool()` can only ever be called for the active chainstate, and that chainstate knows which mempool it's using. We can also remove the `bypass_limits` argument, since that can only be used internally in validation.
  - responsibility for calling `CTxMemPool::check()` is removed from the callers, and run automatically by `ChainstateManager` every time `ProcessTransaction()` is called.

  CJDNS overview
  =====

  CJDNS is like a distributed, shared VPN with multiple entry points where every participant can reach any other participant. All participants use addresses from the `fc00::/8` network (reserved IPv6 range). Installation and configuration is done outside of applications, similarly to VPN (either in the host/OS or on the network router).

  Motivation
  =====

  Even without this PR it is possible to connect two Bitcoin Core nodes through CJDNS manually by using e.g. `-addnode` in environments where CJDNS is set up. However, this PR is necessary for address relay to work properly and automatic connections to be made to CJDNS peers. I.e. to make CJDNS a first class citizen network like IPv4, IPv6, Tor and I2P.

  Considerations
  =====

  An address from the `fc00::/8` network, could mean two things:
  1. Part of a local network, as defined in RFC 4193. Like `10.0.0.0/8`. Bitcoin Core could be running on a machine with such address and have peers with those (e.g. in a local network), but those addresses are not relayed to other peers because they are not globally routable on the internet.
  2. Part of the CJDNS network. This is like Tor or I2P - if we have connectivity to that network then we could reach such peers and we do relay them to other peers.

  So, Bitcoin Core needs to be able to tell which one is it when it encounters a bare `fc00::/8` address, e.g. from `-externalip=` or by looking up the machine's own addresses. Thus a new config option is introduced `-cjdnsreacable`:
  * `-cjdnsreacable=0`: it is assumed a `fc00::/8` address is a private IPv6 (1.)
  * `-cjdnsreacable=1`: it is assumed a `fc00::/8` address is a CJDNS one (2.)

  After setting up CJDNS outside of Bitcoin Core, a node operator only needs to enable this option.
  Addresses from P2P relay/gossip don't need that because they are properly tagged as IPv6 or as CJDNS.

  For testing

The tests `streams_tests/streams_buffered_file` and `streams_tests/streams_buffered_file_rand`
did not use a the temporary directory provided by  `BasicTestingSetup`, so it was not possible
to execute multiple of them in parallel. This fixes that.

To reproduce, run

```sh

```

This executes the test 1000 times, one job per CPU. It works on that commit but mergebase fails quickly.

80dc829be7 tests: Calculate fees more similarly to CFeeRate::GetFee (Andrew Chow)
ce2cc44afd tests: Test for assertion when feerate is rounded down (Andrew Chow)
0fbaef9676 fees: Always round up fee calculated from a feerate (Andrew Chow)

Pull request description:

  When calculating the fee for a feerate, it is possible that the final calculation will have fractional satoshis. Currently those are ignored via truncation which results in the absolute fee being rounded down. Rounding down is problematic because it results in a feerate that is slightly lower than the feerate represented by the `CFeeRate` object. A slightly lower feerate particularly causes issues for coin selection as it can trigger an assertion error. To avoid potentially underpaying the feerate (and the assertion), always round up the calculated fee.

  A test is added for the assertion, along with a comment explaining what happens.

  It is unlikely that a user can trigger this as it requires a very specific set of rounding errors to occur as well as the transaction not needing any change and being right on the lower bound of the exact match window. However I was able to trigger the assertion while running coin selection simulations, albeit after thousands of transactions and with some weird feerates.

The only way that changing bypass_limits from true to false could change

Pull request description:

  This patch disables lock contention logging in the checkqueue_tests as some of these tests are designed to be heavily contested to trigger race conditions or other issues.

refactor: Take Span in SetSeed
This makes calling code less verbose and less fragile. Also, by adding
the CKey::data() member function, it is now possible to call HexStr()
with a CKey object.

fuzz: Rework ConsumeScript
This should make it easier for the fuzz engine to explore multisig code
paths. See discussion in https://github.com/bitcoin/bitcoin/issues/23105

The downside is that all fuzz inputs that use ConsumeScript are now
invalidated and need to be re-generated.

Another downside may be that most multisig scripts from ConsumeScript are
using likely not fully valid pubkeys.

Merge bitcoin/bitcoin#22766: refactor: Clarify and disable unused ArgsManager flags
c5d7e34bd9 scripted-diff: disable unimplemented ArgsManager BOOL/INT/STRING flags (Russell Yanofsky)
b8c069b7a9 refactor: Add explicit DISALLOW_NEGATION ArgsManager flag to clarify flag usage (Russell Yanofsky)
26a50ab322 refactor: Split InterpretOption into Interpret{Key,Value} functions (Russell Yanofsky)

Pull request description:

  This is preparation for #16545 or another PR implementing type validation for ArgsManager settings. It fixes misleading usages of existing flags, prevents flags from being similarly misused in the future, and allows validation logic to be added without breaking backwards compatibility.

  ---

  Currently, ALLOW_{INT|BOOL|STRING} flags don't do any real validation, so current uses of these flags are misleading and will also break backwards compatibility whenever these flags are implemented in a future PR (draft PR is #16545).

  An additional complication is that while these flags don't do any real settings validation, they do affect whether setting negation syntax is allowed.

  Fix this mess by disabling ALLOW_{INT|BOOL|STRING} flags until they are implemented, and adding an unambiguous DISALLOW_NEGATION flag. This is done in three commits, with the first commit cleaning up some code, the second commit adding the DISALLOW_NEGATION flag, and the next commit disabling the ALLOW_{INT|BOOL|STRING} flags.

  None of the changes affect behavior in any way.

2095df7b7b [addrman] Add Add_() inner function, fix Add() return semantics
Previously, Add() would return true if the function created a new
AddressInfo object, even if that object could not be successfully
entered into the new table and was deleted. That would happen if the new
table position was already taken and the existing entry could not be
removed.

Instead, return true if the new AddressInfo object is successfully
entered into the new table. This fixes a bug in the "Added %i addresses"
log, which would not always accurately log how many addresses had been
added.

p2p_addrv2_relay.py and p2p_addr_relay.py need to be updated since they
were incorrectly asserting on the buggy log (assuming that addresses are
added to addrman, when there could in fact be new table position
collisions that prevent some of those address records from being added).

Merge bitcoin/bitcoin#23306: Make AddrMan support multiple ports per IP
92617b7a75 Make AddrMan support multiple ports per IP (Pieter Wuille)

Pull request description:

  For a long part of Bitcoin's history, this codebase has aggressively avoided making automatic connections to anything but nodes running on port 8333. I'd like to propose changing that, and this is a first PR necessary for that.

  The folklore justification (eventually actually added as a comment to the codebase in #20668) is that this is to prevent the Bitcoin P2P network from being leveraged to perform a DoS attack on other services, if their IP/port would get rumoured. It appears, at least the current network scale - and probably significantly larger - that the impact is very low at best (see calculations by vasild in https://github.com/bitcoin/bitcoin/issues/5150#issuecomment-853888909 e.g.). Another possible justification would be a risk that treating different IP:port combinations separately would help perform Eclipse attacks (by an attacker rumouring their own IP with many ports). This concern is (a) no different than what is possible with IPv6 (where large ranges of IP addresses are very cheaply available), and (b) already hopefully sufficiently addressed by addrman's design (which limits access through based selected based on network groups).

  And this policy has downsides too; in particular, a fixed port is easy to detect, and a very obvious sign a Bitcoin node is running there.

  One obstacle in moving away from a default port that is the fact that addrman is currently restricted to a single entry per IP address. If ports are no longer expected to be generally always the default one, we need to deal with the case where conflicting information is relayed. It turns out there is a very natural solution to this: treat (IP,port) combination exactly as we're treating IPs now; this automatically means that the same IP may appear with multiple ports, simply because those would be distinct entries. Given that indexing into addrman's bucket _already_ uses the port number, the only change required is making all addrman lookup be (IP,port) (aka `CService`) based, rather than IP (aka `CNetAddr`) based.

  This PR doesn't include any change to the actual outbound connection preference logic, as perhaps that's something that we want to phase in more gradually.

Pull request description:

  Remove the txmempool <-> validation circular dependency by removing txmempool's dependency on validation. There are two functions in txmempool that need validation right now: `check()` and `removeForReorg()`. This PR removes the dependencies in `check()`.

  This PR also improves the performance of `CTxMemPool::check()` by walking through the entries exactly once, in ascending ancestorcount order, which guarantees that we see parents before children.

Pull request description:

  Currently, various tests use `LegacyScriptPubKeyMan` because it was convenient for the refactor that introduced the `ScriptPubKeyMan` interface. However, with the legacy wallet slated to be removed, these tests should not continue to use `LegacyScriptPubKeyMan` as they are not testing any specific legacy wallet behavior. These tests are changed to use `DescriptorScriptPubKeyMan`s.

  Some of the coin selection tests and benchmarks had a global `testWallet`, but this seemed to cause some issues with ensuring that descriptors were set up in that wallet for each test. Those have been restructured to not have any global variables that may be modified between tests.

  The tests which test specific legacy wallet behavior remain unchanged.

4307849256 [mempool] delete exists(uint256) function (glozow)
d50fbd4c5b create explicit GenTxid::{Txid, Wtxid} ctors (glozow)

Pull request description:

  We use the same type for txids and wtxids, `uint256`. In places where we want the ability to pass either one, we distinguish them using `GenTxid`.

  The (overloaded) `CTxMemPool::exists()` function is defined as follows:
  ```c
  bool exists(const uint256& txid) const { return exists(GenTxid{false, txid}); }
  ```
  It always assumes that a uint256 is a txid, which is a footgunny interface.
  Querying by wtxid returns a false negative if the transaction has a witness. 🐛

  Another approach would be to try both:
  ```c
  bool exists(const uint256& txid) const { return exists(GenTxid{false, txid}) || exists(GenTxid{false, txid}); }
  ```
  But that's slower and wrongfully placing the burden on the callee; the caller always knows whether the hash is a txid or a wtxid.

fadf1186c8 p2p: Use mocktime for ping timeout (MarcoFalke)

Pull request description:

  It is slightly confusing to use mocktime for some times, but not others.

  Start fixing that by making the ping timeout use mocktime.

  The only downside would be that tests that use mocktime disconnect peers after this patch. However, I don't think this is an issue, as the inactivity check is already disabled for all functional tests after commit 6d76b57ca0. Only one unit test needed the inactivity check disabled as part of this patch.

  A nice side effect of this patch is that the `p2p_ping` functional test now runs 4 seconds faster.

b39a477ec6 refactor: Add fs::PathToString, fs::PathFromString, u8string, u8path functions (Russell Yanofsky)

Pull request description:

  The `fs::path` class has a `std::string` constructor which will implicitly convert from strings. Implicit conversions like this are not great in general because they can hide complexity and inefficiencies in the code, but this case is especially bad, because after the transition from `boost::filesystem` to `std::filesystem` in #20744 the behavior of this constructor on windows will be more complicated and can mangle path strings. The `fs::path` class also has a `.string()` method which is inverse of the constructor and has the same problems.

  Fix this by replacing the unsafe method calls with `PathToString` and `PathFromString` function calls, and by forbidding unsafe method calls in the future.
