57ef2a4812 validation: report if pruning prevents completion of verification
Now the verifychain RPC returns false if the checks didn't
finish because the blocks requested to be queried have been pruned.

0c7785bb25 init, validation: Improve handling if VerifyDB() fails due to insufficient dbcache
The rpc command verifychain now fails if the dbcache was not sufficient
to complete the verification at the specified level and depth.

In the same situation, the VerifyDB check during Init will now fail (and lead to
an early shutdown) if the user has explicitly specified -checkblocks or
-checklevel but the check couldn't be executed because of the limited
cache. If the user didn't change any of the two and is using the defaults, log a warning
but don't prevent the node from starting up.

d6f781f1cf validation: return VerifyDBResult::INTERRUPTED if verification was interrupted
This means that the -verifydb RPC will now return false if it
cannot finish due to the node being shutdown.

6360b5302d validation: Change return value of VerifyDB to enum type
This does not change behavior. It is in preparation for
special handling of the case where VerifyDB doesn't finish
for various reasons, but doesn't fail.

Merge bitcoin/bitcoin#25344: New outputs argument for bumpfee/psbtbumpfee
4c8ecccdcd test: add tests for `outputs` argument to `bumpfee`/`psbtbumpfee` (Seibart Nedor)
c0ebb98382 wallet: add `outputs` arguments to `bumpfee` and `psbtbumpfee` (Seibart Nedor)
a804f3cfc0 wallet: extract and reuse RPC argument format definition for outputs (Seibart Nedor)

Pull request description:

  This implements a modification of the proposal in #22007: instead of **adding** outputs to the set of outputs in the original transaction, the outputs given by `outputs` argument **completely replace** the outputs in the original transaction.

  As noted below, this makes it easier to "cancel" a transaction or to reduce the amounts in the outputs, which is not the case with the original proposal in #22007, but it seems from the discussion in this PR that the **replace** behavior is more desirable than **add** one.

Merge bitcoin/bitcoin#26844: Net: Pass MSG_MORE flag when sending non-final network messages (round 2)
691eaf8873 Pass MSG_MORE flag when sending non-final network messages (Matt Whitlock)

Pull request description:

  **N.B.:** This is my second attempt at introducing this optimization. #12519 (2018) was closed in deference to switching to doing gathering socket writes using `sendmsg(2)`, which I agree would have superior performance due to fewer syscalls, but that work was apparently abandoned in late 2018. Ever since, Bitcoin Core has continued writing tons of runt packets to the wire. Can we proceed with my halfway solution for now?

  ----

  Since Nagle's algorithm is disabled, each and every call to `send(2)` can potentially generate a separate TCP segment on the wire. This is especially inefficient when sending the tiny header preceding each message payload.

  Linux implements a `MSG_MORE` flag that tells the kernel not to push the passed data immediately to the connected peer but rather to collect it in the socket's internal transmit buffer where it can be combined with data from successive calls to `send(2)`. Where available, specify this flag when calling `send(2)` in `CConnman::SocketSendData(CNode &)` if the data buffer being sent is not the last one in `node.vSendMsg`.

Merge bitcoin/bitcoin#27035: test: simplify and speedup mempool_updatefromblock.py by using MiniWallet
dee8549be3 test: simplify and speedup mempool_updatefromblock.py by using MiniWallet (Sebastian Falbesoner)

Pull request description:

  This PR simplifies the functional test mempool_updatefromblock.py by using MiniWallet in order to avoid manual low-level tx creation (signing, outputs selection, fee calculation). Most of the tedious work is done by the method `MiniWallet.send_self_transfer_multi` (calling `create_self_transfer_multi` internally) which supports spending a given set of UTXOs and creating a certain number of outputs.

  As a nice side-effect, the test's performance increases significantly (~3.5x on my system):

  ```

  The arguments `start_input_txid` and `end_address` have been removed from the `transaction_graph_test` method, as they are currently unused and I don't see them being needed for future tests.

Pull request description:

  This is an alternative to #25354 (by my benchmarking, somewhat faster), subsumes #25712, and adds additional test vectors.

  It separates the multiple-of-64-bytes-only "core" logic (which becomes simpler) from a layer around which performs caching/slicing to support arbitrary byte amounts. Both have their uses (in particular, the MuHash3072 code can benefit from multiple-of-64-bytes assumptions), plus the separation results in more readable code. Also, since FastRandomContext effectively had its own (more naive) caching on top of ChaCha20, that can be dropped in favor of ChaCha20's new built-in caching.

  I thought about rebasing #25712 on top of this, but the changes before are fairly extensive, so redid it instead.

Merge bitcoin/bitcoin#27076: verify-commits: Bump trusted git root to after most recent laanwj merge
6ada37d44c verify-commits: Bump trusted git root to after most recent laanwj merge (Andrew Chow)

Pull request description:

  To prepare for the removal of laanwj's key from trusted key (#27054), the trusted git root needs to be newer than the most recent merge commit signed by his key.

  This can be tested by removing the laanwj's key from trusted keys (e.g. by merging with #27054) and running `verify-commits.py` with `--clean-merge 0`: `./contrib/verify-commits/verify-commits.py --clean-merge 0 HEAD~`. (`--clean-merge 0` disables the clean merge check which will checkout some commits, which results in the `trusted-keys` used in checking of subsequent commits to be different than expected).

Merge bitcoin-core/gui#603: Add settings.json prune-prev, proxy-prev, onion-prev settings
9d3127b11e Add settings.json prune-prev, proxy-prev, onion-prev settings (Ryan Ofsky)

Pull request description:

  With #602, if proxy and pruning settings are disabled in the GUI and the GUI is restarted, proxy and prune values are not stored anywhere. So if these settings are enabled in the future, default values will be shown, not previous values.

  This PR stores previous values so they will preserved across restarts. I'm not sure I like this behavior because showing default values seems simpler and safer to me. Previous values may just have been set temporarily and may have never actually worked, and it adds some code complexity to store them.

  This PR is one way of resolving #596. Other solutions are possible and could be implemented as alternatives.

Merge bitcoin/bitcoin#26584: cli: include local ("unroutable") peers in -netinfo table
77192c9598 cli: include local ("unreachable") peers in -netinfo table (Matthew Zipkin)

Pull request description:

  Closes https://github.com/bitcoin/bitcoin/issues/26579

  The `-netinfo` dashboard did not list peers that were connected via "unroutable" networks. This included local peers including local-network peers. Personally, I run one bitcoind instance on my network that is used by other services like Wasabi Wallet and LND running on other machines.

  This PR adds an "npr" (not publicly routable) column to the table of networks (ipv4, ipv6, onion, etc) so that every connection to the node is listed, and the totals are accurate as they relate to max inbound and max outbound limits.

  Example connecting in regtest mode to one local and one remote peer:

66a86ebabb wallet: keep track of when the passphrase is needed when rescanning
Wallet passphrases are needed to top up the keypool during a
rescan. The following RPCs need the passphrase when rescanning:
    - `importdescriptors`
    - `rescanblockchain`

The following RPCs use the information about whether or not the
passphrase is being used to ensure that full rescans are able to
take place:
    - `walletlock`
    - `encryptwallet`
    - `walletpassphrasechange`

772671245d test: p2p: check that headers message with invalid proof-of-work disconnects peer (Sebastian Falbesoner)

Pull request description:

  One of the earliest anti-DoS checks done after receiving and deserializing a `headers` message from a peer is verifying whether the proof-of-work is valid (called in method `PeerManagerImpl::ProcessHeadersMessage`):
  f227e153e8/src/net_processing.cpp (L2752-L2762)
  The called method `PeerManagerImpl::CheckHeadersPoW` calls `Misbehaving` with a score of 100, i.e. leading to an immediate disconnect of the peer:
  f227e153e8/src/net_processing.cpp (L2368-L2372)

  This PR adds a simple test for both the misbehaving log and the resulting disconnect. For creating a block header with invalid proof-of-work, we first create one that is accepted by the node (the difficulty field `nBits` is copied from the genesis block) and based on that the nonce is modified until we have block header hash prefix that is too high to fulfill even the minimum difficulty.

Merge bitcoin/bitcoin#27080: Wallet: Zero out wallet master key upon locking so it doesn't persist in memory
3a11adc700 Zero out wallet master key upon lock (John Moffett)

Pull request description:

  When an encrypted wallet is locked (for instance via the RPC `walletlock`), the documentation indicates that the key is removed from memory:

  b92d609fb2/src/wallet/rpc/encrypt.cpp (L157-L158)

  However, the vector (a `std::vector<unsigned char, secure_allocator<unsigned char>>`) is merely _cleared_. As it is a member variable, it also stays in scope as long as the wallet is loaded, preventing the secure allocator from deallocating. This allows the key to persist indefinitely in memory. I confirmed this behavior on my macOS machine by using an open-source third party memory inspector ("Bit Slicer"). I was able to find my wallet's master key in Bit Slicer after unlocking and re-locking my encrypted wallet. I then confirmed the key data was at the address in LLDB.

  This PR manually fills the bytes with zeroes before calling `clear()` by using our `memory_cleanse` function, which is designed to prevent the compiler from optimizing it away. I confirmed that it does remove the data from memory on my machine upon locking.

  Note: An alternative approach could be to call `vMasterKey.shrink_to_fit()` after the `clear()`, which would trigger the secure allocator's deallocation. However, `shrink_to_fit()` is not _guaranteed_ to actually change the vector's capacity, so I think it's unwise to rely on it.

  ## Edit: A little more clarity on why this is an improvement.

  Since `mlock`ed memory is guaranteed not to be swapped to disk and our threat model doesn't consider a super-user monitoring the memory in realtime, why is this an improvement? Most importantly, consider hibernation. Even `mlock`ed memory may get written to disk. From the `mlock` [manpage](https://man7.org/linux/man-pages/man2/mlock.2.html):

  > (But be aware that the suspend mode on laptops and some desktop computers will save a copy of the system's RAM to disk, regardless of memory locks.)

  As far as I can tell, this is true of [Windows](https://web.archive.org/web/20190127110059/https://blogs.msdn.microsoft.com/oldnewthing/20140207-00/?p=1833#:~:text=%5BThere%20does%20not%20appear%20to%20be%20any%20guarantee%20that%20the%20memory%20won%27t%20be%20written%20to%20disk%20while%20locked.%20As%20you%20noted%2C%20the%20machine%20may%20be%20hibernated%2C%20or%20it%20may%20be%20running%20in%20a%20VM%20that%20gets%20snapshotted.%20%2DRaymond%5D) and macOS as well.

  Therefore, a user with a strong OS password and a strong wallet passphrase could still have their keys stolen if a thief takes their (hibernated) machine and reads the permanent storage.
