Pull request description:
Issues:
- `CBlockIndex` member functions `GetBlockPos()`, `GetUndoPos()`, `IsAssumedValid()`, `RaiseValidity()`, and `IsValid()` and block storage functions `WriteUndoDataForBlock()` and `IsBlockPruned()` are missing thread safety lock annotations to help ensure that they are called with mutex cs_main to avoid bugs like #22895. Doing this also enables the next step:
- `CBlockIndex::nStatus` may be racy, i.e. potentially accessed by multiple threads, see #17161. A solution is to guard it by cs_main, along with fellow data members `nFile`, `nDataPos` and `nUndoPos`.
This pull:
- adds thread safety lock annotations for the functions listed above
- guards `CBlockIndex::nStatus`, `nFile`, `nDataPos` and `nUndoPos` by cs_main
How to review and test:
- debug build with clang and verify there are no `-Wthread-safety-analysis` warnings
- review the code to verify each annotation or lock is necessary and sensible, or if any are missing
- look for whether taking a lock can be replaced by a lock annotation instead
- for more information about Clang thread safety analysis, see

This commit extends our inbound eviction protection to CJDNS peers to
favorise the diversity of peer connections, as peers connected
through the CJDNS network are otherwise disadvantaged by our eviction
criteria for their higher latency (higher min ping times) relative
to IPv4 and IPv6 peers.
The `networks` array is order-dependent in the case of a tie in
candidate counts between networks; earlier array members receive
priority in the case of a tie.
Therefore, we place CJDNS candidates before I2P, localhost, and onion
ones in terms of opportunity to recover unused remaining protected
slots from the previous iteration, estimating that most nodes allowing
several inbound privacy networks will have more onion, localhost or
I2P peers than CJDNS ones, as CJDNS support is only being added in the
upcoming v23.0 release.
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

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.

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.

fa7238300c fuzz: Limit fuzzed time to years 2000-2100 (MarcoFalke)
Pull request description:
It doesn't make sense to fuzz times in the past, as Bitcoin Core will refuse to start in the past.
Fix that and also remove a sanitizer suppression, which would be hit in net_processing in `ProcessMessage`:
```cpp
if (addr.nTime <= 100000000 || addr.nTime > nNow + 10 * 60)
addr.nTime = nNow - 5 * 24 * 60 * 60; // <-- Here
```
This changes the format of fuzz inputs. Previously a time value was (de)serialized as 40 bytes, now it is 32 bytes.

b5c9bb5cb9 util: Restore GetIntArg saturating behavior (James O'Beirne)
Pull request description:
The new locale-independent atoi64 method introduced in #20452 parses large integer values higher than maximum representable value as 0 instead of the maximum value, which breaks backwards compatibility. This commit restores compatibility and adds test coverage for this case in terms of the related GetIntArg and strtoll functions.
Specifically, command line or bitcoin.conf integer values greater than `9223372036854775807` (`2**63-1`) used to be parsed as `9223372036854775807` before #20452. Then #20452 caused them to be parsed as `0`. And after this PR they will be parsed as `9223372036854775807` again.

Make it possible to override from the command line (without recompiling)

Make it possible to override from the command line (without recompiling)
the addrman check ratio in the common `TestingSetup::m_node::addrman`
(used by all unit tests) instead of hardcoding it to 0:
```
test_bitcoin --run_test="transaction_tests/tx_valid" -- -checkaddrman=1
```
In addrman unit tests, make it possible to override the check ratio from
the command line, without recompiling:
```
test_bitcoin --run_test="addrman_tests/*" -- -checkaddrman=1
```
Also, make the arguments of the constructor of `AddrManTest` the
same as the arguments of `AddrMan`.
Retrieve the command line arguments from the fuzzer and save them for
later retrieval by `BasicTestingSetup` so that we gain extra flexibility
of passing any config options on the test command line, e.g.:
```
FUZZ=addrman ./src/test/fuzz/fuzz --checkaddrman=5
```
A fuzz test should call `MakeNoLogFileContext<>()` in its initialize
function in order to invoke the constructor of `BasicTestingSetup`,
which sets `gArgs`.
Retrieve the command line arguments from boost and pass them to
`BasicTestingSetup` so that we gain extra flexibility of passing any
config options on the test command line, e.g.:
```
test_bitcoin -- -printtoconsole=1 -checkaddrman=5
```
BlockManager is a large data structure, and cs_main is not required to
take its address or access every part of it. Individual BlockManager
fields and methods which do require cs_main like m_block_index and
LookupBlockIndex are already annotated separately, and these other
annotations describe locking requirements more accurately and do a
better job enforcing thread safety.
Since cs_main is not needed to access the address of the m_block object,
this commit drops cs_main LOCK calls which were added pointlessly to
satisfy this annotation in the past.

f7086fd8ff Add src/wallet/* code to wallet:: namespace (Russell Yanofsky)
90fc8b089d Add src/node/* code to node:: namespace (Russell Yanofsky)
Pull request description:
There are no code changes, this is just adding `namespace` and `using` declarations and `node::` or `wallet::` qualifiers in some places.
Motivations for this change are:
- To make it easier to see when node and wallet code is being accessed places where it shouldn't be. For example if GUI code is accessing node and wallet internals or if wallet and node code are referencing each other.
- To make source code organization clearer ([#15732](https://github.com/bitcoin/bitcoin/issues/15732)), being able to know that `wallet::` code is in `src/wallet/`, `node::` code is in `src/node/`, `init::` code is in `src/init/`, `util::` code is in `src/util/`, etc.
Reviewing with `git log -p -n1 -U0 --word-diff-regex=.` can be helpful to verify this is only updating declarations, not changing code.

Pull request description:
There are 2 proposed fixups in discussions in #23280 which I have not implemented:
1. An overhaul to return types and an option type for the two `*Chainstate` functions: https://github.com/bitcoin/bitcoin/pull/23280#issuecomment-984149564
- The change reintroduces stringy return types and is quite involved. It could be discussed in a separate PR.
2. Passing in the unix time to `VerifyChainstate` instead of a callback to get the time: https://github.com/bitcoin/bitcoin/pull/23280#discussion_r765051533
- I'm not sure it matters much whether it's a callback or just the actual unix time. Also, I think `VerifyDB` can take quite a while, and I don't want to impose that the function have to "run quickly" in order to have it be correct.
If reviewers feel strongly about either of the two fixups listed above, please feel free to open a PR based on mine and I'll close this one!
