2bb25ce502 wallet: remove unused 'accept_no_keys' arg from decryption process (furszy)
Pull request description:
Found it while reviewing other PR. Couldn't contain myself from cleaning it up.
The wallet decryption process (`CheckDecryptionKey()` and `Unlock()`)
contains an arg 'accept_no_keys,' introduced in #13926, that has
never been used.
Additionally, this also removes the unimplemented `SplitWalletPath`
function.

A SQLiteBatch need to wait for any other batch to finish writing before
it can begin writing, otherwise db txn state may be incorrectly
modified. To enforce this, each SQLiteDatabase has a semaphore which
acts as a lock and is acquired by a batch when it begins a write, erase,
or a transaction, and is released by it when it is done.
To avoid deadlocking on itself for writing during a transaction,
SQLiteBatch also keeps track of whether it has begun a transaction.
e7fd70f4b6 [test] make v2transport arg in addconnection mandatory and few cleanups (stratospher)
Pull request description:
- make `v2transport` argument in `addconnection` regression-testing only RPC mandatory. https://github.com/bitcoin/bitcoin/pull/24748#discussion_r1470738750
- previously it was an optional arg with default `false` value.
- only place this RPC is used is in the [functional tests](11b436a66a/test/functional/test_framework/test_node.py (L742)) where we always pass the appropriate `v2transport` option to the RPC anyways. (and that too just for python dummy peer(`P2PInterface`) and bitcoind(`TestNode`) interactions)
- rename `v2_handshake()` to `_on_data_v2_handshake()` https://github.com/bitcoin/bitcoin/pull/24748#discussion_r1466958424
- more compact return statement in `wait_for_reconnect()` https://github.com/bitcoin/bitcoin/pull/24748#discussion_r1466979708
- assertion to check that empty version packets are received from `TestNode`.

9332c7edda wallet: Write bestblock to watchonly and solvable wallets (Ava Chow)
Pull request description:
A transaction does not necessarily have to belong to either the migrated wallet (with the private keys) and the watchonly wallet (with watchonly things), it could have multiple outputs with each isminetype. So we should be putting such transactions in one or the other wallet, but rather putting it in both.
I've added a test for this behavior, however the test also revealed a few other issues. Notably, it revealed that `migratewallet` would have the watchonly wallet rescan from genesis when it is reloaded at the end of migration. This could be a cause for migration appearing to be very slow. This is resolved by first writing best block records to the watchonly and solvable wallets, as well as updating the test to make sure that rescans don't happen.
The change to avoid rescans also found an issue where some of our early exits would result in unloading the wallet even though nothing happened. So there is also a commit to reload the wallet for such early exits.

Pull request description:
While rebasing #28710 after #28976 was merged, I realized that although blank wallets were being moved to sqlite, `WALLET_FLAG_DESCRIPTORS` was not being set so those blank wallets would still continue to be treated as legacy wallets.

Requesting historical blocks from network limited peers is a
direct disconnection cause.
The node must only request the blocks who know for sure the
limited peer can provide.
It is possible for a transaction that has an output that belongs to the
mgirated wallet, and another output that belongs to the watchonly
wallet. Such transaction should appear in both wallets during migration.
Migration will unload loaded wallets prior to beginning. It will then
perform some checks which may exit early. Such unloaded wallets should
be reloaded prior to exiting.
When migrating, we should also be writing the bestblock record to the
watchonly and solvable wallets to avoid rescanning on the reload as that
can be slow.

facaa66b49 refactor: Add missing default constructor to prevector iterators (MarcoFalke)
Pull request description:
Currently prevector iterators have many issues:
* Forward iterators (and stronger) must be default constructible (https://eel.is/c++draft/forward.iterators#1.2). Otherwise, some functions can not be instantiated, like `std::minmax_element`.
* Various `const` issues with random access iterators. For example, a `const iterator` is different from a `const_iterator`, because the first one holds a mutable reference and must also return it without `const`. Also, `operator+` must be callable regardless of the iterator object's `const`-ness.
* When adding an offset to random access iterators, both `x+n` and `n+x` must be specified, see https://eel.is/c++draft/random.access.iterators#tab:randomaccessiterator
Fix all issues.
Also, upgrade the `std::random_access_iterator_tag` (C++17) to `std::contiguous_iterator_tag` (C++20)

8c127ff1ed wallet: Skip key and script migration for blank wallets (Andrew Chow)
Pull request description:
Blank wallets (wallets without any keys are scripts) are being detected as already being descriptor wallets even though they are not. This is because the check for whether a wallet is already a descriptor wallet uses the presence of a `LegacyScriptPubKeyMan` which is only setup when keys or scripts are found. This PR resolves this issue by checking for the descriptor wallet flag instead and subsequently skipping the keys and scripts part of migration for blank wallets.

0bef1042ce net: enable v2transport by default (Pieter Wuille)
Pull request description:
This enables BIP324's v2 transport by default (see #27634):
* Inbound connections will auto-sense whether v1 or v2 is in use.
* Automatic outbound connections will use v2 if `NODE_P2P_V2` was set in addr gossip, but retry with v1 if met with immediate failure.
* Manual outbound connections will default to v2, but retry with v1 if met with immediate failure.
It remains possible to run with `-v2transport=0` to disable all of these, and make all outbound and inbound connections v1. It also remains possible to specify the `v2transport` argument to the `addnode` RPC as `false`, to disable attempting a v2 connection for that particular added node.

Pull request description:
Discovered while was reviewing #29112, specifically https://github.com/bitcoin/bitcoin/pull/29112#pullrequestreview-1821862931.
If the db handler that initiated the database transaction is destroyed,
the ongoing transaction cannot be left dangling when the db txn fails
to abort. It must be forcefully reverted; otherwise, any subsequent
db handler executing a write operation will dump the dangling,
to-be-reverted transaction data to disk.
This not only breaks the isolation property but also results in the
improper storage of incomplete information on disk, impacting
the wallet consistency.
This PR fixes the issue by resetting the db connection, automatically
rolling back the transaction (per https://www.sqlite.org/c3ref/close.html)
when the handler object is being destroyed and the txn abortion failed.

`TestNode::add_outbound_p2p_connection()` is the only place where
addconnection test-only RPC is used. here, we always pass the

currently the v2transport option for addconnection RPC is optional.
so simply make the v2transport option mandatory instead.

Pull request description:
Derived from #28120 discussion.
By relocating the peer desirable services flags into the peer manager, we
allow the connections acceptance process to handle post-IBD potential
stalling scenarios.
The peer manager will be able to dynamically adjust the services flags
based on the node's proximity to the tip (back and forth). Allowing the node
to recover from the following post-IBD scenario:
Suppose the node has successfully synced the chain, but later experienced
dropped connections and remained inactive for a duration longer than the limited
peers threshold (the timeframe within which limited peers can provide blocks). In
such cases, upon reconnecting to the network, the node might only establish
connections with limited peers, filling up all available outbound slots. Resulting
in an inability to synchronize the chain (because limited peers will not provide
blocks older than the `NODE_NETWORK_LIMITED_MIN_BLOCKS` threshold).

the ongoing transaction cannot be left dangling when the db txn fails

db handler executing a write operation will dump the dangling,
to-be-reverted transaction data to disk.
This not only breaks the database isolation property but also results
in the improper storage of incomplete information on disk, impacting

By encapsulating sqlite3_exec into its own standalone method
and introducing the 'SQliteExecHandler' class, we enable the
ability to test db statements execution failures within the
unit test framework.
This is used in the following-up commit to exercise a deadlock
and improve our wallet db error handling code.
Moreover, the future encapsulation of other sqlite functions
within this class will contribute to minimize the impact of
any future API changes.

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)

bbf218d061 crypto: remove sha256_sse4 from the base crypto helper lib (Cory Fields)
4dbd0475d8 crypto: remove use of BUILD_BITCOIN_INTERNAL macro in sha256 (Cory Fields)
Pull request description:
Replace it with a more explicit `DISABLE_OPTIMIZED_SHA256` and clean up some.
The macro was originally used by libbitcoinconsensus which opts out of optimized sha256 for the sake of simplicity.
Also remove the `BUILD_BITCOIN_INTERNAL` define from libbitcoinkernel for now as it does not export an api. When it does we can pick a less confusing define to control its exports.
Removing the define should have the effect of enabling sha256 optimizations for the kernel.

8023640a71 qt: Avoid non-self-contained Windows header (Hennadii Stepanov)
Pull request description:
Using the `windows.h` header guarantees correctness regardless of the content of other headers.
For more details, please refer to https://stackoverflow.com/questions/4845198/fatal-error-no-target-architecture-in-visual-studio
Fixes the MSVC build when using the upcoming CMake-based build system and Qt packages installed via the vcpkg package manager.

ACK 8023640a71. It's not completely clear to me why this currently works, but I don't think it's worth wasting more time on. `windows.h` seems more correct regardless.

d298ff8b62 During IBD, prune as much as possible until we get close to where we will eventually keep blocks (Luke Dashjr)
Pull request description:
This should reduce pruning flushes even more, speeding up IBD with pruning on systems that have a sufficient dbcache.
Assumes 1 MB per block between tip and best header chain. Simply adds this to the buffer pruning is trying to leave available, which results in pruning almost everything up until we get close to where we need to be keeping blocks.

6cc2a38c13 build: add sanitizer flags to configure output (fanquake)
08cd5aca18 build: always set -g -O2 in CORE_CXXFLAGS (fanquake)
Pull request description:
Rather than trying to sporadically rely on / override Autoconf default behaviour. Just always override (if unset), and always set the flags we want (which are the same as the Autoconf defaults).
Removes the need for duplicate code to clear (if not overridden) `CXXFLAGS`.
Fixes cases of "missing" `-O2`. i.e this PR when running a Valgrind CI job with changes here:
```bash
CXXFLAGS = -g -O2 -fdebug-prefix-map=$(abs_top_srcdir)=. -Wstack-protector -fstack-protector-all -mbranch-protection=bti -Werror -fsanitize=fuzzer -gdwarf-4
```
Fixes configure output to reflect actual compilation flag ordering, so it's useful.
Note that if we do still end up with a duplicate "-g -O2" when compiling, that has no effect, and I don't really thinks it's something worth trying to optimize.
