- Add an optional `supports_v2_p2p` parameter to specify if the inbound
and outbound connections support v2 P2P protocol.
- In the `addconnection_callback` which gets called when creating
outbound connections, call the `addconnection` RPC with v2 P2P protocol
support enabled.
- When a v2 TestNode makes an outbound connection to a P2PInterface node
which doesn't support v2 but is advertised as v2 by some malicious
intermediary, the TestNode sends 64 bytes ellswift. The v1 node doesn't
understand this and disconnects. Then the v2 TestNode reconnects by
sending a v1/version message.
Messages are built, encrypted and sent over the socket in v2
connections. If a race condition happens between python's main
thread and p2p thread with both of them trying to send a message,
it's possible that the messages get encrypted with wrong keystream.
Messages are built and sent over the socket in v1 connections.
So there's no problem if messages are sent in the wrong order.

Instantiate this object when the connection supports v2 P2P transport
protocol.
- When a P2PConnection is opened, perform initiate_v2_handshake() if the
connection is an initiator. application layer messages are only sent after
the initial v2 handshake is over (for both initiator and responder).
The class `EncryptedP2PState` stores the 4 32-byte keys, session id,
garbage terminators, whether it's an initiator/responder, whether the
initial handshake has been completed etc.. It also contains functions
to perform the v2 handshake and to encrypt/decrypt p2p v2 messages.
- In an inbound connection to TestNode, P2PConnection is the initiator
and `initiate_v2_handshake()`, `complete_handshake()`, `authenticate_handshake()`
are called on it. [ TestNode <----------------- P2PConnection ]
- In an outbound connection from TestNode, P2PConnection is the responder
and `respond_v2_handshake()`, `complete_handshake()`, `authenticate_handshake()`
are called on it. [ TestNode -----------------> P2PConnection ]
This avoids circular dependency happening when importing MAGIC_BYTES.
Before,
p2p.py <--import for EncryptedP2PState-- v2_p2p.py
| ^
| |
└---------import for MAGIC_BYTES----------┘
Now, MAGIC_BYTES are kept separately in messages.py

9ac114e5cd Throw error if invalid parameters passed to getnetworkhashps RPC endpoint (Jameson Lopp)
Pull request description:
When writing some scripts that iterated over many blocks to generate hashrate estimates I realized that my script was going out of range of the current chain tip height but was not encountering any errors.
I believe that passing an invalid block height to this function but receiving the hashrate estimate for the chain tip instead should be considered unexpected behavior.

Pull request description:
This makes the functional test suite compatible with BIP324, so that

should succeed (currently, 12 tests fail for me on master).
Includes two commits by TheStack I found in an old discussion https://github.com/bitcoin/bitcoin/pull/28331#discussion_r1326714164
Note that even though all tests should pass, the python `p2p.py` module will do v2 connections only after the merge of #24748, so that for now only connections between two full nodes will actually run v2.
Some of the fixed tests were added with `--v2transport` to the test runner. Though after #24748 we might also want to consider running the entire suite with `--v2transport` in some CI.

Pull request description:
With Python 3.9 / [PEP 585](https://peps.python.org/pep-0585/), [type hinting has become a little less awkward](https://docs.python.org/3.9/whatsnew/3.9.html#type-hinting-generics-in-standard-collections), as for collection types one doesn't need to import the corresponding capitalized types (`Dict`, `List`, `Set`, `Tuple`, ...) anymore, but can use the built-in types directly (see https://peps.python.org/pep-0585/#implementation for the full list).
This PR applies the replacement for all Python scripts (i.e. in the contrib and test folders) for the basic types, i.e.:
- typing.Dict -> dict
- typing.List -> list
- typing.Set -> set
- typing.Tuple -> tuple
For an additional check, I ran mypy 1.6.1 on both master and the PR branch via
```
$ mypy --ignore-missing-imports --explicit-package-bases $(git ls-files "*.py")
```
and verified that the output is identical -- (from the 22 identified problems, most look like false-positives, it's probably worth it to go deeper here and address them in a follow-up though).

fa6b053b5c mempool: persist with XOR (MarcoFalke)
Pull request description:
Currently the `mempool.dat` file stores data received from remote peers as-is. This may be problematic when a program other than Bitcoin Core tries to interpret them by accident. For example, an anti-virus program or other program may scan the file and move it into quarantine, or delete it, or corrupt it.
While the local wallet is expected to re-submit any pending transactions, unrelated transactions may be missing from the mempool after a restart. This may cause fee estimates to be off, or may cause block relay to be slower.
Fix this, similar to https://github.com/bitcoin/bitcoin/pull/6650, by rolling a random XOR pattern over the dat file when writing or reading it.
Obviously this can only protect against programs that accidentally and unintentionally are trying to mess with the dat file. Any program that intentionally wants to mess with the dat file can still trivially do so.

- "transport_protocol_type" of inbound peer before version handshake
is "detecting" on p2p v2 nodes (as opposed to "v1" for p2p v1)
- size of a ping/pong message is 29 bytes (as opposed to 32 for p2p v1)
- for the sendmsgtopeer RPC sub-test, enforce p2p v1 connection to
have a peer id of zero
By renaming the "command" send_cli arg. The old name was unsuitable
because the "addnode" RPC has its own "command" arg, leading to
ambiguity when included in kwargs.
Can be tested with
"python3 wallet_multiwallet.py --usecli --v2transport"
which fails on master because of this (python throws a TypeError).
Before, a global -v2transport provided to the test would be dropped
when restarting the node within a test and specifying any extra_args.
Fix this by adding "v2transport=1" to args (not extra_args) based
on the global parameter, and deciding for each (re)start of the node
based on this default and test-specific extra_args
(which take precedence over args) whether v2 should be used.
5039c346ca init: completely remove `-zapwallettxes` (remaining hidden option) (Sebastian Falbesoner)
Pull request description:
The `-zapwallettxes` functionality has been removed in v0.21.0 (see commit 3340dbadd3 / PR #19671), with the parameter being kept as hidden option, to inform users via an exit error that `abandontransaction` should be used instead.
As any guides that still suggest to use `-zapwallettxes` would refer to a Bitcoin Core version that is EOL since many years (i.e. <= v0.20.x), it is highly unlikely that the error caused by the option is still relevant for any user, hence it seems fine to remove it now.

2574b7e177 net/rpc: Check all resolved addresses in ConnectNode rather than just one (Sergi Delgado Segura)
Pull request description:
## Rationale
Currently, `addnode` has a couple of corner cases that allow it to either connect to the same peer more than once, hence wasting outbound connection slots, or add redundant information to `m_added_nodes`, hence making Bitcoin iterate through useless data on a regular basis.
### Connecting to the same node more than once
In general, connecting to the same node more than once is something we should try to prevent. Currently, this is possible via `addnode` in two different ways:
1. Calling `addnode` more than once in a short time period, using two equivalent but distinct addresses
2. Calling `addnode add` using an IP, and `addnode onetry` after with an address that resolved to the same IP
For the former, the issue boils down to `CConnman::ThreadOpenAddedConnections` calling `CConnman::GetAddedNodeInfo` once, and iterating over the result to open connections (`CConman::OpenNetworkConnection`) on the same loop for all addresses.`CConnman::ConnectNode` only checks a single address, at random, when resolving from a hostname, and uses it to check whether we are already connected to it.
An example to test this would be calling:
```
bitcoin-cli addnode "127.0.0.1:port" add
bitcoin-cli addnode "localhost:port" add
```
And check how it allows us to perform both connections some times, and some times it fails.
The latter boils down to the same issue, but takes advantage of `onetry` bypassing the `CConnman::ThreadOpenAddedConnections` logic and calling `CConnman::OpenNetworkConnection` straightaway. A way to test this would be:
```
bitcoin-cli addnode "127.0.0.1:port" add
bitcoin-cli addnode "localhost:port" onetry
```
### Adding the same peer with two different, yet equivalent, addresses
The current implementation of `addnode` is pretty naive when checking what data is added to `m_added_nodes`. Given the collection stores strings, the checks at `CConnman::AddNode()` basically check wether the exact provided string is already in the collection. If so, the data is rejected, otherwise, it is accepted. However, ips can be formatted in several ways that would bypass those checks.
Two examples would be `127.0.0.1` being equal to `127.1` and `[::1]` being equal to `[0:0:0:0:0:0:0:1]`. Adding any pair of these will be allowed by the rpc command, and both will be reported as connected by `getaddednodeinfo`, given they map to the same `CService`.
This is less severe than the previous issue, since even tough both nodes are reported as connected by `getaddednodeinfo`, there is only a single connection to them (as properly reported by `getpeerinfo`). However, this adds redundant data to `m_added_nodes`, which is undesirable.
### Parametrize `CConnman::GetAddedNodeInfo`
Finally, this PR also parametrizes `CConnman::GetAddedNodeInfo` so it returns either all added nodes info, or only info about the nodes we are **not** connected to. This method is used both for `rpc`, in `getaddednodeinfo`, in which we are reporting all data to the user, so the former applies, and to check what nodes we are not connected to, in `CConnman::ThreadOpenAddedConnections`, in which we are currently returning more data than needed and then actively filtering using `CService.fConnected()`

49d953281d fuzz: explicitly specify llvm-symbolizer path in runner (fanquake)
Pull request description:
It's not completely clear to me why this needs to be explicitly specified in some environments, and not in others, while at the same time that `llvm-symbolizer` is already in PATH, but this has fixed the 2 issues outlined in https://github.com/bitcoin/bitcoin/pull/28147.
Use `LLVM_SYMBOLIZER_PATH` as the env var, as that is somewhat also used inside LLVM, but not consistently, i.e it's checked for in the asan_symbolize script, but not in in the ubsan_symbolize script, or from in compiler-rt.
Alternative to #28804.

The signing test for the large miniscript can sometimes take longer than
the 30 second timeout, depending on the load on my system. Increasing it
to 90 seconds seems to be good enough.

The `-zapwallettxes` functionality has been removed in v0.21.0
(see commit 3340dbadd3 / PR #19671),
with the parameter being kept as hidden option, to inform users via
an exit error that `abandontransaction` should be used instead.
As any guides that still suggest to use `-zapwallettxes` would refer to
a Bitcoin Core version that is EOL since many years (i.e. <= v0.20.x),
it is highly unlikely that the error caused by the option is still
relevant for any user, hence it seems fine to remove it now.

Pull request description:
This is part of #27463. It splits off the `MiniMiner`-specific changes from #26711 for ease of review, as suggested in https://github.com/bitcoin/bitcoin/pull/26711#issuecomment-1786392253.
- Allow using `MiniMiner` on transactions that aren't in the mempool.
- Make `target_feerate` param of `BuildMockTemplate` optional, meaning "don't stop building the template until all the transactions have been selected."
- Add clarification for how this is different from `target_feerate=0` (https://github.com/bitcoin/bitcoin/pull/26711#discussion_r1377019133)
- Track the order in which transactions are included in the template to get the "linearization order" of the transactions.
- Tests
Reviewers can take a look at #26711 to see how these functions are used to linearize the `AncestorPackage` there.
