cfa575266b Optimize CHECKSIGADD Script Validation (Jeremy Rubin)
Pull request description:
This is a mild validation improvement that improves performance by caching some signature data when you have a Taproot script fragment that uses CHECKSIGADD Multisignatures with sighash single. In some basic testing I showed this to have about a 0.6% speedup during block validation for a block with a lot of CHECKSIGADDs, but that was with the entirety of block validation so the specific impact on the script interpreter performance should be a bit more once you subtract things like coin fetching. If desired I can produce a more specific/sharable bench for this, the code I used to test was just monkey patching the existing taproot tests since generating valid spends is kinda tricky. But it's sort of an obvious win so I'm not sure it needs a rigorous bench, but I will tinker on one of those while the code is being reviewed for correctness.
The overhead of this approach is that:
1. ScriptExecutionData is no longer const
2. around 32 bytes of extra stack space
3. zero extra hashing since we only cache on first use

c5b36b1c1b Mempool Update Cut-Through Optimization (Jeremy Rubin)
c49daf9885 [TESTS] Increase limitancestorcount in tournament RPC test to showcase improved algorithm (Jeremy Rubin)
Pull request description:
Often when we're updating mempool entries we update entries that we ultimately end up removing the updated entries shortly thereafter. This patch makes it so that we filter for such entries a bit earlier in processing, which yields a mild improvement for these cases, and is negligible overhead otherwise.
There's potential for a better -- but more sophisticated -- algorithm that can be used taking advantage of epochs, but I figured it is better to do something that is simple and works first and upgrade it later as the other epoch mempool work proceeds as it makes the patches for the epoch algorithm simpler to understand, so you can consider this as preparatory work. It could either go in now if it is not controversial, or we could wait until the other patch is ready to go.

8588591965 guix: ignore additioanl failing certvalidator test (fanquake)
e8a6c888e4 build: point to latest commit on the master branch (fanquake)
Pull request description:
Guix recently force pushed to their `version-1.4.0` branch, causing #24040. At the time #24042 pointed to the newest commit on that branch, fixing #24040, but it didn't actually build. Guix have now [temporarily removed](https://lists.gnu.org/archive/html/guix-devel/2022-01/msg00313.html) their `version-1.4.0` branch, while they incorporate additional fixes.
This PR updates our guix time-machine to point to a recent commit on the guix master branch, so that builds can resume for all hosts apart from Windows. Windows builds are broken due to what looks like an upstream issue, which results in e failure to build the [`mingw-w64-x86_64-winpthreads package`](https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/mingw.scm#n137). The build fails with:
```bash

```
This info will be sent upstream. You can likely recreate the failure with `guix build mingw-w64-x86_64-winpthreads`.
Once Guix is at a point of tagging a 1.4.0 release commit (after re-branching and RCs), we can shift our time-machine to point to it. If a change is made upstream in relation to the Windows issue we are seeing, we will adjust our time-machine commit earlier.

Pull request description:
`PoissonNextSend` and `PoissonNextSendInbound` are used in the p2p code to obfuscate various regularly occurring processes, in order to make it harder for others to get timing-based information deterministically.
The naming of these functions has been confusing to several people (including myself, see also #23347) because the resulting random timestamps don't follow a Poisson distribution but an exponential distribution (related to events in a Poisson process, hence the name). This PR
- moves `PoissonNextSend()` out of `net` to `random` and renames it to `GetExponentialRand()`
- moves `PoissonNextSendInbound()` out of `CConnman` to `PeerManager` and renames it to `NextInvToInbounds()`
- adds documentation for these functions

36012ef143 qa: test descriptors with mixed xpubs and const pubkeys (Antoine Poinsot)
Pull request description:
Writing unit tests for Miniscript descriptors i noticed that `test/descriptor_tests`'s `DoCheck()` assumes that a descriptor would either contain only extended keys or only const pubkeys: if it detects an xpub in the descriptor it would assert the number of cached keys is equal to the number of keys in the descriptor, which does not hold if the descriptor also contains const (raw?) public keys since we only cache parent xpubs.

faedb111d2 refactor tests to fix ubsan suppressions (MarcoFalke)
Pull request description:
The ubsan suppressions for test files have several issues:
* They bloat the suppressions file, distracting from real bugs
* They are file-wide, thus suppressing any other (newly introduced) issues in the same file
* Some of them are causing compile issues with -Wimplicit-int-conversion
Fix all issues by making the integer truncations or sign changes explicit.
This is a refactor that shouldn't change the test binary unless compiled with sanitizers.

e2ab9f83f8 build: disable external signer on Windows (fanquake)
Pull request description:
This change explicitly disables support for external signing when targeting Windows and OpenBSD. The driver for this is that Boost Process uses boost::filesystem internally, when targeting Windows, which gets in the way of removing our usage of it (#20744). While we could adjust #20744 to still link against the Boost libs when building for Windows, that would be disappointing, as we wouldn't have cleanly removed the Boost usage we're trying too (including the build infrastructure), and, we'd be in a position where we would be building releases differently depending on the platform, which is something I want to avoid.
After discussion with Sjors, Achow and Hebasto, this seemed like a reasonable step to move #20744 forward (as-is). Note that support for external signing ([while already being experimental](https://github.com/bitcoin/bitcoin/blob/master/doc/external-signer.md#example-usage)), could be considered even more experimental on Windows. Also, oddly, we have external-signing [explicitly disabled in our Windows (cross-compile) CI](807169e10b/ci/test/00_setup_env_win64.sh (L16)), it's not clear why this is the case, as, if it's a feature being built into releases, it should be being built and tested in the CI which is most-like the release process.
There is an [issue open upstream](https://github.com/boostorg/process/issues/207), in regards to migrating Boost Process to std::filesystem, or having an option to use it. However there hasn't been much discussion since it was opened ~9 months ago. There is another related issue here: https://github.com/klemens-morgenstern/boost-process/issues/164.
Resolves#24036.

dc5d6b0d47 fs: Make compatible with boost 1.78 (Andrew Chow)
Pull request description:
Boost 1.78 removed `operator+` in a way that breaks our usage of it in a subclass. A [proposed workaround](https://github.com/boostorg/filesystem/issues/223#issuecomment-1000230207) for this is to cast the argument to `boost::filesystem::path`, and this is backwards compatible with older versions of boost.
Additionally, it appears that `fs::canonical` no longer removes trailing slashes. This was causing a test to fail. The solution is to explicitly remove the trailing separator in the one place that `fs::canonical` is used.
Lastly, `fs::create_directories` now has an error message saying `create_directories` instead of `create_directory`. This caused wallet_multiwallet.py to fail. The error message check has been updated to be able accept either string.
Fixes#23846

bf044ef9ec build: specify hosts for qrencode package (fanquake)
Pull request description:
Similar to how we specify the OS's we build Qt for, specify which OS's
we will build qrencode for (a qt dependency). This commit alone doesn't
change anything, but when we start supporting other OS's, i.e #23948,
where we wont support qt (or at least initially), it'll skip building
the qrencode package, which would be unused.
I'll rebase the other *BSD changes on top of this.

86a4a15bdc Highlight DNS request part (Prayank)
Pull request description:
_What?_
Highlight DNS requests part in Proxy section
_Why?_
1. DNS requests are very important while considering privacy
2. Lot of users might skip reading it because of the way it is mixed with everything else in the doc right now
3. I have seen lot of users ignoring DNS requests or unaware of such things while using privacy tools
_How?_
Initially I had tried keeping these lines separate from code block but [Jonatack didn't agree with the changes](https://github.com/bitcoin/bitcoin/pull/21157#discussion_r618177116). Harding suggested using [bold/italic in `<pre></pre>`](https://github.com/bitcoin/bitcoin/pull/21157#discussion_r644364143). I have used the suggestions from previous PR and added `---`
This is a part of alternative described in https://github.com/bitcoin/bitcoin/pull/22316

No behavior change.
This code was introduced in 5add7a7 before we required C++11, which is
why the struct was needed. As we are now using more modern C++ and this
is the only place where lockpoints are updated for mempool entries, it
is more idiomatic to call `modify` with a lambda.

Behavior change: don't quit right after LimitMempoolSize() when a
package is partially submitted. We should still send
TransactionAddedToMempool notifications for
transactions that were submitted.
Not behavior change: add a new package validation result for mempool logic errors.
The previous interface required callers to guess that the tx had been
swapped and look up the tx again by txid to find a `MEMPOOL_ENTRY`
result. This is a confusing interface.
Instead, explicitly tell the caller that this transaction was
`DIFFERENT_WITNESS` in the result linked to the mempool entry's wtxid.
This gives the caller all the information they need in 1 lookup, and
they can query the mempool for the other transaction if needed.

92a0f7e58d test: parse the command line arguments in unit tests (Vasil Dimov)
Pull request description:
Previously command line arguments passed to unit and fuzz tests would be ignored by the tests themselves. They would be used by the boost test framework (e.g. `--run_test="addrman_tests/*"`) or by the fuzzer (e.g. `-runs=1`). However both provide ways to pass down the extra arguments to the test itself. Use that, parse the arguments and make them available to the tests via `gArgs`.
This makes the tests more flexible as they can be run with any bitcoind config option specified on the command line.
When creating `AddrMan` objects in tests, use `-checkaddrman=` (if provided) instead of hardcoding the check ratio in many different places. See https://github.com/bitcoin/bitcoin/pull/20233#issuecomment-889813074 for further motivation for this.

5574e6ed52 refactor: replace RecursiveMutex `m_callbacks_mutex` with Mutex (Sebastian Falbesoner)
3aa258109e scripted-diff: rename `m_cs_callbacks_pending` -> `m_callbacks_mutex` (Sebastian Falbesoner)
Pull request description:
This PR is related to #19303 and gets rid of the RecursiveMutex `m_cs_callbacks_pending`. All of the critical sections (6 in total) only directly access the guarded elements, i.e. it is not possible that within one section another one is called, and we can use a regular Mutex:
807169e10b/src/scheduler.cpp (L138-L145)807169e10b/src/scheduler.cpp (L152-L160)807169e10b/src/scheduler.cpp (L169-L172)807169e10b/src/scheduler.cpp (L184-L187)807169e10b/src/scheduler.cpp (L197-L199)807169e10b/src/scheduler.cpp (L203-L206)
Also, it is renamed to adapt to the (unwritten) naming convention to use the `_mutex` suffix rather than the `cs_` prefix.

fac22fd36b log: Remove GetAdjustedTime from IBD header progress estimation (MarcoFalke)
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.
