Pull request description:
This PR adds missing test coverage for disconnecting peers which don't offer the desirable service flags in their VERSION message:
https://github.com/bitcoin/bitcoin/blob/5f3a0574c45477288bc678b15f24940486084576/src/net_processing.cpp#L3384-L3389
This check is relevant for the connection types "outbound-full-relay", "block-relay-only" and "addr-fetch" (see `CNode::ExpectServicesFromConn(...)`). Feeler connections always disconnect, which is also tested here.
In lack of finding a proper file where this test would fit in, I created a new one. Happy to take suggestions there.

Adds a new boolean parameter `wait_for_disconnect` to the
`add_outbound_p2p_connection` method. If set, the node under
test is checked to disconnect immediately after receiving the
version message (same logic as for feeler connections).
|
|
Otherwise, a run with
test_runner.py --v2transport=1 --previous-releases --extended
would hit the removed assert for wallet_backwards_compatibility.py
|
|
This changes the default behavior, individual tests can overwrite this option.
As a result, it is possible to run the entire test suite with
--v2transport, and all connections to the python p2p will then use it.
Also adjust several tests that are already running with --v2transport in the
test runner (although they actually made v1 connection before this change).
This is done in the same commit so that there isn't an
intermediate commit in which the CI fails.
|
|
By adding to the test framework a wait until the v2 handshake
is completed, so that p2p_sendtxrcncl.py (which doesn't need
to be changed itself) doesnt't send out any other messages before that.

Pull request description:
This PR introduces support for v2 P2P encryption(BIP 324) in the existing functional test framework and adds functional tests for the same.
### commits overview
1. introduces a new class `EncryptedP2PState` to store the keys, functions for performing the initial v2 handshake and encryption/decryption.
3. this class is used by `P2PConnection` in inbound/outbound connections to perform the initial v2 handshake before the v1 version handshake. Only after the initial v2 handshake is performed do application layer P2P messages(version, verack etc..) get exchanged. (in a v2 connection)
- `v2_state` is the object of class `EncryptedP2PState` in `P2PConnection` used to store its keys, session-id etc.
- a node [advertising](https://github.com/stratospher/blogosphere/blob/main/integration_test_bip324.md#advertising-to-support-v2-p2p) support for v2 P2P is different from a node actually [supporting v2 P2P](https://github.com/stratospher/blogosphere/blob/main/integration_test_bip324.md#supporting-v2-p2p) (differ when false advertisement of services occur)
- introduce a boolean variable `supports_v2_p2p` in `P2PConnection` to denote if it supports v2 P2P.
- introduce a boolean variable `advertises_v2_p2p` to denote whether `P2PConnection` which mimics peer behaviour advertises V2 P2P support. Default option is `False`.
- In the test framework, you can create Inbound and Outbound connections to `TestNode`
1. During **Inbound Connections**, `P2PConnection` is the initiator [`TestNode` <--------- `P2PConnection`]
- Case 1:
- if the `TestNode` advertises/signals v2 P2P support (means `self.nodes[i]` set up with `"-v2transport=1"`), different behaviour will be exhibited based on whether:
1. `P2PConnection` supports v2 P2P
2. `P2PConnection` does not support v2 P2P
- In a real world scenario, the initiator node would intrinsically know if they support v2 P2P based on whatever code they choose to run. However, in the test scenario where we mimic peer behaviour, we have no way of knowing if `P2PConnection` should support v2 P2P or not. So `supports_v2_p2p` boolean variable is used as an option to enable support for v2 P2P in `P2PConnection`.
- Since the `TestNode` advertises v2 P2P support (using "-v2transport=1"), our initiator `P2PConnection` would send:
1. (if the `P2PConnection` supports v2 P2P) ellswift + garbage bytes to initiate the connection
2. (if the `P2PConnection` does not support v2 P2P) version message to initiate the connection
- Case 2:
- if the `TestNode` doesn't signal v2 P2P support; `P2PConnection` being the initiator would send version message to initiate a connection.
2. During **Outbound Connections** [TestNode --------> P2PConnection]
- initiator `TestNode` would send:
- (if the `P2PConnection` advertises v2 P2P) ellswift + garbage bytes to initiate the connection
- (if the `P2PConnection` advertises v2 P2P) version message to initiate the connection
- Suppose `P2PConnection` advertises v2 P2P support when it actually doesn't support v2 P2P (false advertisement scenario)
- `TestNode` sends ellswift + garbage bytes
- `P2PConnection` receives but can't process it and disconnects.
- `TestNode` then tries using v1 P2P and sends version message
- `P2PConnection` receives/processes this successfully and they communicate on v1 P2P
4. the encrypted P2P messages follow a different format - 3 byte length + 1-13 byte message_type + payload + 16 byte MAC
5. includes support for testing decoy messages and v2 connection downgrade(using false advertisement - when a v2 node makes an outbound connection to a node which doesn't support v2 but is advertised as v2 by some malicious
intermediary)
### run the tests

- 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.
|
|
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).

consistently using `platform.system()`

Pull request description:
There are at least three ways to detect the operating system in Python3:
- `os.name` (https://docs.python.org/3.9/library/os.html#os.name)
- `sys.platform` (https://docs.python.org/3.9/library/sys.html#sys.platform)
- `platform.system()` (https://docs.python.org/3.9/library/platform.html#platform.system)
We are currently using all of them in functional tests (both in individual tests and shared test framework code), which seems a bit messy. This PR consolidates into using `platform.system()`, as it appears to be one most consistent and easy to read (see also [IRC discussion](https://bitcoin-irc.chaincode.com/bitcoin-core-dev/2023-12-08#989301;) and table below). `sys.platform` is inconsistent as it has the major version number encoded for BSD systems, which doesn't make much sense for e.g. OpenBSD, where there is no concept of major versions, but instead the version is simply increased by 0.1 on each release.
Note that `os.name` is still useful to detect whether we are running a POSIX system (see `BitcoinTestFramework.skip_if_platform_not_posix`), so for this use-case it is kept as only exception. The following table shows values for common operating systems, found via
```
$ python3 -c "import os; import sys; import platform; print(os.name, sys.platform, platform.system())"
```
| OS | os.name | sys.platform | platform.system() |
|--------------|---------|--------------|--------------------|
| Linux 6.2.0 | posix | linux | Linux |
| MacOS* | posix | darwin | Darwin |
| OpenBSD 7.4 | posix | openbsd7 | OpenBSD |
| Windows* | nt | win32 | Windows |
\* = I neither have a MacOS nor a Windows machine available, so I extracted the values from documentation and our current code. Also I'm relying on CI for testing the relevant code-paths. Having reviewers to this this locally would be very appreciated, if this gets Concept ACKed.

Only relying on the number of peers for detecting a new connection
suffers from race conditions, as unrelated previous peers could
disconnect at anytime in-between. Use the more robust approach of
watching for an increased highest peer id instead (again using the
`getpeerinfo` RPC call), with a newly introduced context manager
method `TestNode.wait_for_new_peer()`.
Fixes #29009.

Pull request description:
This makes the functional test suite compatible with BIP324, so that
`python3 test_runner.py --v2transport`
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.

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.

The python p2p node should mirror this behavior by not sending a `getaddr` message when it is not the initiator of the connection.

Two recently added tests (PR #28625 / commit 2e31250027ac580a7a72221fe2ff505b30836175
and PR #28634 / commit 3bb51c29df596aab2c1fde184667cee435597715)
introduced a bug by wrongly using the `assert_debug_log` helper.
Instead of passing the expected debug string in a list as expected, it
was passed as bare string, which is then interpretered as a list of
characters, very likely leading the debug log assertion pass even if the
intended message is not appearing.
In order to avoid bugs like this in the future, enforce that the
`{un}expected_msgs` parameters are lists.

This is unnecessary and caused test failures. The backward
compatibility tests are meant to find regressions in the
current codebase, not to detect bugs in older releases.

Bitcoind nodes send getaddr msgs only to outbound nodes (and ignore those
received by outgoing connections). The python p2p node should mirror
this behavior by not sending a getaddr message when it is not the

0f83ab407ec5aa0591c54c03bcf408c7f2f0a192 test: display abrupt shutdown errors in console output (furszy)
Pull request description:
Making it easier to debug errors in the CI environment,
particularly in scenarios where it's not immediately clear
what happened nor which node crashed (or shutdown abruptly).
A bit of context:
Currently, the test framework redirects each node's stderr output
stream to a different temporary file inside each node's data directory.
While this is sufficient for storing the error, it isn't very helpful for
understanding what happened just by reading the CI console output.
Most of the time, reading the stderr file in the CI environment is not
possible, because people don't have access to it.
Testing Note:
The displayed error difference can be observed by cherry-picking this
commit https://github.com/furszy/bitcoin-core/commit/9cc5393c0f24c774b4a59706fc7c7873a59573e7 on top of this branch and running any

9eac5a0529f869075f0331e40d322c34fc8fc2af [functional test] transaction orphan handling (glozow)
61e77bb901bca038b46064dc4531e12c2ab50673 [test framework] make it easier to fast-forward setmocktime (glozow)
Pull request description:
I was doing some mutation testing (through reckless refactoring) locally and found some specific behaviors in orphan handling that weren't picked up by tests. Adding some of these test cases now can maybe help with reviewing refactors like #28031.
- Parent requests aren't sent immediately. A delay is added and the requests are filtered by AlreadyHaveTx before they are sent, which means you can't use fake orphans to probe precise arrival timing of a tx.
- Parent requests include all that are not AlreadyHaveTx. This means old confirmed parents may be requested.
- The node does not give up on orphans if the peer responds to a parent request with notfound. This means that if a parent is an old confirmed transaction (in which notfound is expected), the orphan should still be resolved.
- Rejected parents can cause an orphan to be dropped, but it depends on the reason and only based on txid.
- Rejected parents can cause an orphan to be rejected too, by both wtxid and txid.
- Requests for orphan parents should be de-duplicated with "regular" txrequest. If a missing parent has the same hash as an in-flight request, it shouldn't be requested.
- Multiple orphans with overlapping parents should not cause duplicated parent requests.

feb0096139e9e864632d2826d2e213b26146fff1 test: fix intermittent failure in p2p_getaddr_caching (Martin Zumsande)
Pull request description:
Fixes #28133
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:
The node in this test was never really needed, because the compatibility tests shouldn't be used to test previous releases. (The test suite of the previous release itself should be used for that). So remove it.
Also, other test changes. (See individual commits)

Only the combined addr:port of source and destination
must be unique. If the destination is different, the same addr:port
for the source may be used by the OS.

read() fails in text mode when the unicode hasn't been fully written
yet. Fixes: "wallet_importdescriptors.py: can't decode bytes in position
228861-228863: unexpected end of data"

debug_log_bytes returned "an opaque number when in text mode"
(https://docs.python.org/3/tutorial/inputoutput.html#methods-of-file-objects),
not the number of bytes.
Fix this by using binary mode or text mode (with the same encoding)
consistently when opening the file for ftell() and read().

20b49460b35268db59f7efcb02736b0e31191a74 test: remove race in the user-agent reception check (Vasil Dimov)
Pull request description:
In `add_p2p_connection()` we connect to `bitcoind` from the Python client and check that it has received our version string.
This check looked up the last/newest entry from `getpeerinfo` RPC, assuming that it must be the connection we have just opened. But this will not be the case if a new inbound or outbound connection is made to/from `bitcoind` in the meantime.
Instead of the last entry in `getpeerinfo`, check all and find the one which corresponds to our connection using our outgoing address:port tuple which is unique.

The thread does not only load blocks, it loads the mempool and,
in a future commit, will start the indexes as well.
Also, renamed the 'ThreadImport' function to 'ImportBlocks'
And the 'm_load_block' class member to 'm_thread_load'.
-BEGIN VERIFY SCRIPT-
sed -i "s/ThreadImport/ImportBlocks/g" $(git grep -l ThreadImport -- ':!/doc/')

The new name better explains that the function handles fallbacks,
without listing all in the function name.

Also, add datadir_path property to TestNode
|
|
Seems odd to hardcode all parent directory names in the path for no good
reason.
Also, add wallet_path property to TestNode.
Also, rework wallet_backup.py test for scripted-diff in the next commit.

It seems odd to return `EXIT_SUCCESS` when the node aborted
execution due a fatal internal error or any post-init problem
that triggers an unrequested shutdown.
e.g. blocks or coins db I/O errors, disconnect block failure,
failure during thread import (external blocks loading process
error), among others.

Show an error on startup if a bitcoin datadir that is being used contains a
`bitcoin.conf` file that is ignored. There are two cases where this could
happen:
- One case reported in
https://github.com/bitcoin/bitcoin/issues/27246#issuecomment-1470006043
happens when a bitcoin.conf file in the default datadir (e.g.
$HOME/.bitcoin/bitcoin.conf) has a "datadir=/path" line that sets different
datadir containing a second bitcoin.conf file. Currently the second
bitcoin.conf file is ignored with no warning.
- Another way this could happen is if a -conf= command line argument points
to a configuration file with a "datadir=/path" line and that specified path
contains a bitcoin.conf file, which is currently ignored.
This change only adds an error message and doesn't change anything about way
settings are applied. It also doesn't trigger errors if there are redundant
-datadir or -conf settings pointing at the same configuration file, only if
they are pointing at different files and one file is being ignored.
