333333356f431d8ef318f685860d25ff99d4b457 fuzz: [refactor] Use std::span over FuzzBufferType in descriptor utils (MarcoFalke)
Pull request description:
Accepting "expensive" fuzz inputs which have no real use-case is problematic, because it prevents the fuzz engine from spending time on the next useful fuzz input.
Also, this may lead to problems, where the fuzz target can not be run at all on some platforms. See https://github.com/bitcoin/bitcoin/issues/34110.
Fixes https://github.com/bitcoin/bitcoin/issues/34110 by rejecting those useless and expensive inputs (via the third commit)
Can be tested by running the input and checking the time before and after the changes here:
```
curl -fLO '1cf91e0c6b'

```
Also, the second commit fixes https://github.com/bitcoin/bitcoin/issues/31066.

997e7b4d7cf7c4622938798423447375383184c0 init: Fix non-zero code on interrupt (sedited)
Pull request description:
Reported by dergoegge on irc.
An interrupt does not create a failure exit code during normal operation. This should also be the case when interrupt is triggered during initialization. However a failure exit code is currently returned if an interrupt occurs during init. Fix this by making `AppInitMain` return true instead of false on interrupt, which further up the call stack currently sets the `EXIT_FAILURE` code. Also add a check for the interrupt condition during GUI startup. Returning `EXIT_SUCCESS` seems to be the usual behaviour for daemons, see the discussion on IRC for this: https://www.erisian.com.au/bitcoin-core-dev/log-2026-01-08.html#l-146 .

d59b4cdb5772917ee13e48552d51662160104b62 mining: rename getCoinbaseTx() to ..RawTx() (Sjors Provoost)
Pull request description:
The first commit renames `getCoinbaseTx()` to `getCoinbaseRawTx()` to reflect that it returns a serialised transaction. This does not impact IPC clients, because they do not use the function name.
The second commit then introduces a replacement `getCoinbase()` that provides a struct with everything clients need to construct a coinbase. This avoids clients having to parse and manipulate our dummy transaction.
Deprecate but don't remove `getCoinbaseRawTx()`, `getCoinbaseCommitment()` and `getWitnessCommitmentIndex()`.
After this change we can drop these deprecated methods, which in turn would allow us to clear the dummy transaction from the `getBlock()` result. But that is left for a followup to keep this PR focussed. See https://github.com/Sjors/bitcoin/pull/106 for an approach.
Expand the `interface_ipc.py` functional test to document its usage.

To improve privacy, broadcast locally submitted transactions (from the `sendrawtransaction` RPC) to the P2P network only via Tor or I2P short-lived connections, or to IPv4/IPv6 peers but through the Tor network.
* Introduce a new connection type for private broadcast of transactions with the following properties:
* started whenever there are local transactions to be sent
* opened to Tor or I2P peers or IPv4/IPv6 via the Tor proxy
* opened regardless of max connections limits
* after handshake is completed one local transaction is pushed to the peer, `PING` is sent and after receiving `PONG` the connection is closed
* ignore all incoming messages after handshake is completed (except `PONG`)
* Broadcast transactions submitted via `sendrawtransaction` using this new mechanism, to a few peers. Keep doing this until we receive back this transaction from one of our ordinary peers (this takes about 1 second on mainnet).
* The transaction is stored in peerman and does not enter the mempool.
* Once we get an `INV` from one of our ordinary peers, then the normal flow executes: we request the transaction with `GETDATA`, receive it with a `TX` message, put it in our mempool and broadcast it to all our existent connections (as if we see it for the first time).
* After we receive the full transaction as a `TX` message, in reply to our `GETDATA` request, only then consider the transaction has propagated through the network and remove it from the storage in peerman, ending the private broadcast attempts.
The messages exchange should look like this:
```
tx-sender >--- connect -------> tx-recipient
tx-sender >--- VERSION -------> tx-recipient (dummy VERSION with no revealing data)
tx-sender <--- VERSION -------< tx-recipient
tx-sender <--- WTXIDRELAY ----< tx-recipient (maybe)
tx-sender <--- SENDADDRV2 ----< tx-recipient (maybe)
tx-sender <--- SENDTXRCNCL ---< tx-recipient (maybe)
tx-sender <--- VERACK --------< tx-recipient
tx-sender >--- VERACK --------> tx-recipient
tx-sender >--- INV/TX --------> tx-recipient
tx-sender <--- GETDATA/TX ----< tx-recipient
tx-sender >--- TX ------------> tx-recipient
tx-sender >--- PING ----------> tx-recipient
tx-sender <--- PONG ----------< tx-recipient
tx-sender disconnects
```
Whenever a new transaction is received from `sendrawtransaction` RPC, the node will send it to a few (`NUM_PRIVATE_BROADCAST_PER_TX`) recipients right away. If after some time we still have not heard anything about the transaction from the network, then it will be sent to 1 more peer (see `PeerManagerImpl::ReattemptPrivateBroadcast()`).
A few considerations:
* The short-lived private broadcast connections are very cheap and fast wrt network traffic. It is expected that some of those peers could blackhole the transaction. Just one honest/proper peer is enough for successful propagation.
* The peers that receive the transaction could deduce that this is initial transaction broadcast from the transaction originator. This is ok, they can't identify the sender.

<summary>How to test this?</summary>
Thank you, @stratospher and @andrewtoth!
Start `bitcoind` with `-privatebroadcast=1 -debug=privatebroadcast`.
Create a wallet and get a new address, go to the Signet faucet and request some coins to that address:
```bash
build/bin/bitcoin-cli -chain="signet" createwallet test
build/bin/bitcoin-cli -chain="signet" getnewaddress
```
Get a new address for the test transaction recipient:
```bash
build/bin/bitcoin-cli -chain="signet" loadwallet test
new_address=$(build/bin/bitcoin-cli -chain="signet" getnewaddress)
```
Create the transaction:
```bash
# Option 1: `createrawtransaction` and `signrawtransactionwithwallet`:
txid=$(build/bin/bitcoin-cli -chain="signet" listunspent | jq -r '.[0] | .txid')
vout=$(build/bin/bitcoin-cli -chain="signet" listunspent | jq -r '.[0] | .vout')
echo "txid: $txid"
echo "vout: $vout"
tx=$(build/bin/bitcoin-cli -chain="signet" createrawtransaction "[{\"txid\": \"$txid\", \"vout\": $vout}]" "[{\"$new_address\": 0.00001000}]" 0 false)
echo "tx: $tx"
signed_tx=$(build/bin/bitcoin-cli -chain="signet" signrawtransactionwithwallet "$tx" | jq -r '.hex')
echo "signed_tx: $signed_tx"
# OR Option 2: `walletcreatefundedpsbt` and `walletprocesspsbt`:
# This makes it not have to worry about inputs and also automatically sends back change to the wallet.
# Start `bitcoind` with `-fallbackfee=0.00003000` for instance for 3 sat/vbyte fee.
psbt=$(build/bin/bitcoin-cli -chain="signet" walletcreatefundedpsbt "[]" "[{\"$new_address\": 0.00001000}]" | jq -r '.psbt')
echo "psbt: $psbt"
signed_tx=$(build/bin/bitcoin-cli -chain="signet" walletprocesspsbt "$psbt" | jq -r '.hex')
echo "signed_tx: $signed_tx"
```
Finally, send the transaction:
```bash
raw_tx=$(build/bin/bitcoin-cli -chain="signet" sendrawtransaction "$signed_tx")
echo "raw_tx: $raw_tx"
```

Further extensions:
* Have the wallet do the private broadcast as well, https://github.com/bitcoin/bitcoin/issues/11887 would have to be resolved.
* Have the `submitpackage` RPC do the private broadcast as well, [draft diff in the comment below](https://github.com/bitcoin/bitcoin/pull/29415#pullrequestreview-2972293733), thanks ismaelsadeeq!
* Add some stats via RPC, so that the user can better monitor what is going on during and after the broadcast. Currently this can be done via the debug log, but that is not convenient.
* Make the private broadcast storage, currently in peerman, persistent over node restarts.
* Add (optional) random delay before starting to broadcast the transaction in order to avoid correlating unrelated transactions based on the time when they were broadcast. Suggested independently of this PR [here](https://github.com/bitcoin/bitcoin/issues/30471).
* Consider periodically sending transactions that did not originate from the node as decoy, discussed [here](https://github.com/bitcoin/bitcoin/pull/29415#discussion_r2035414972).
* Consider waiting for peer's FEEFILTER message and if the transaction that was sent to the peer is below that threshold, then assume the peer is going to drop it. Then use this knowledge to retry more aggressively with another peer, instead of the current 10 min. See [comment below](https://github.com/bitcoin/bitcoin/pull/29415#issuecomment-3258611648).
* It may make sense to be able to override the default policy -- eg so submitrawtransaction can go straight to the mempool and relay, even if txs are normally privately relayed. See [comment below](https://github.com/bitcoin/bitcoin/pull/29415#issuecomment-3427086681).
* As a side effect we have a new metric available - the time it takes for a transaction to reach a random node in the network (from the point of view of the private broadcast recipient the tx originator is a random node somewhere in the network). This can be useful for monitoring, unrelated to privacy characteristics of this feature.
---
_A previous incarnation of this can be found at https://github.com/bitcoin/bitcoin/pull/27509. It puts the transaction in the mempool and (tries to) hide it from the outside observers. This turned out to be too error prone or maybe even impossible._

An interrupt does not create a failure exit code during normal
operation. This should also be the case when interrupt is triggered
during initialization. However a failure exit code is currently returned
if an interrupt occurs during init. Fix this by making `AppInitMain` return
true instead of false, which further up the call stack sets the
`EXIT_FAILURE` code. Also add a check for the interrupt condition during
GUI startup.

They are exactly the same, but the descriptor utils should not prescribe
to use the FuzzBufferType. Using a dedicated type for them clarifies
that the utils are not tied to FuzzBufferType.
Also, while touching the lines, use `const` only where it is meaningful.
f78f6f1dc8e16d5a8a23749e77bc3bf17c91ae42 wallettool: do not use fs::remove_all in createfromdump cleanup (Ava Chow)
Pull request description:
As pointed out in https://github.com/bitcoin/bitcoin/pull/34156#issuecomment-3716728670, it is possible for `createfromdump` to also accidentally delete the entire wallets directory if the wallet name is the empty string and the dumpfile contains a checksum error.
This is also fixed by removing the files created by only removing the directory for named wallets, and avoiding the use of `fs::remove_all`.

4ed0693a3f2a427ef9e7ad016930ec29fa244995 wallet: RestoreWallet failure, erase only what was created (furszy)
Pull request description:
Minimal fix for #34128.
The issue occurs during the migration of a legacy unnamed wallet
(the legacy "default" wallet). When the migration fails, the cleanup
logic is triggered to roll back the state, which involves erasing the
newly created descriptor wallets directories. Normally, this only
affects the parent directories of named wallets, since they each
reside in their own directories. However, because the unnamed
wallet resides directly in the top-level `/wallets/` folder, this
logic accidentally deletes the main directory.
The fix ensures that only the wallet.dat file of the unnamed wallet
is touched and restored, preserving the wallet in BDB format and
leaving the main `/wallets/` directory intact.
#### Story Line:
#32273 fixed a different set of issues and, in doing so, uncovered
this one.
Before the mentioned PR, backups were stored in the same directory
as the wallet.dat file. On a migration failure, the backup was then
copied to the top-level `/wallets/` directory. For the unnamed legacy
wallet, the wallet directory is the `/wallets/` directory, so the source
and destination paths were identical. As a result, we threw early in the
`fs::copy_file` call ([here](https://github.com/bitcoin/bitcoin/blob/29.x/src/wallet/wallet.cpp#L4572)) because the file already existed, as we
were trying to copy the file onto itself. This caused the cleanup logic
to abort early on and never reach the removal line.
#### Testing Notes:
Cherry-pick the test commit on top of master and run it. You will
see the failure and realize the reason by reading the test code.

fafbc70d48e1fb42c4ed3da609e5f30c4cc39418 rpc: [wallet] Use unsigned type for tx version in sendall (MarcoFalke)
Pull request description:
It is confusing to parse the unsigned tx version as a signed type. Also, it makes it harder to use the integer sanitizer.
Can be tested via:
* Build with the flags `-DCMAKE_C_COMPILER='clang' -DCMAKE_CXX_COMPILER='clang++' -DSANITIZERS=undefined,integer,float-divide-by-zero`
* Set the existing suppressions: `export UBSAN_OPTIONS="suppressions=$(pwd)/test/sanitizer_suppressions/ubsan:print_stacktrace=1:halt_on_error=0:report_error_type=1"`
* Start the RPC server, e.g. `./bld-cmake/bin/bitcoin-qt -datadir=/tmp -regtest -server`
* Call the sendall RPC, e.g. `./bld-cmake/bin/bitcoin-cli -datadir=/tmp -regtest -named sendall '["bcrt1qlrt3xps4wxpfcjmljrayr2ualczmnfvd4vzdq3"]' fee_rate=1.234 version=-1`

Because the default wallet has no name, the watch-only and solvables
wallets created during migration end up having no name either.
This fixes it by applying the same prefix name we use for the backup
file for an unnamed default wallet.
Before: watch-only wallet named "_watchonly"
After: watch-only wallet named "default_wallet_watchonly"
Right now, after migration the last message users see is "migration completed",
but the migration isn't actually finished yet. We still need to load the new wallets
to ensure consistency, and if that fails, the migration will be rolled back. This
can be confusing for users.
This change logs the post-migration loading step and if a wallet fails to load and
the migration will be rolled back.
When migrating any legacy unnamed wallet, a failed migration would
cause the cleanup logic to remove its parent directory. Since this
type of legacy wallet lives directly in the main '/wallets/' folder,
this resulted in unintentionally erasing all wallets, including the
backup file.
To be fully safe, we will no longer call `fs::remove_all`. Instead,
we only erase the individual db files we have created, leaving
everything else intact. The created wallets parent directories are
erased only if they are empty.
As part of this last change, `RestoreWallet` was modified to allow
an existing directory as the destination, since we no longer remove
the original wallet directory (we only remove the files we created
inside it). This also fixes the restore of top-level default wallets
during failures, which were failing due to the directory existence
check that always returns true for the /wallets/ directory.
This bug started after:
f6ee59b6e2
Previously, the `fs::copy_file` call was failing for top-level wallets,
which prevented the `fs::remove_all` call from being reached.
Track what RestoreWallet creates so only those files and directories
are removed during a failure and nothing else. Preexisting paths
must be left untouched.
Note:
Using fs::remove_all() instead of fs::remove() in RestoreWallet does
not cause any problems currently, but the change is necessary for the
next commit which extends RestoreWallet to work with existing directories,
which may contain files that must not be deleted.

Pull request description:
Part of #30289, follow-up to #32545.
This gets rid of `FixLinearization()` by integrating the functionality into `Linearize()`, and makes txgraph exploit that (by delaying fixing of clusters until their first re-linearization). It also reduces (but does not eliminate) the number of calls to `PostLinearize`, as the SFL linearization effectively performs something very similar to postlinearization when loading in an existing linearization already.

Pull request description:
The ctest target `bench_sanity_check` has many issues:
* With sanitizers enabled, it is one of the slowest targets, often taking several minutes. See https://github.com/bitcoin/bitcoin/issues/32770#issuecomment-2984264066.
* There is no insight from ctest into how long each individual sanity check takes.
* On a timeout, or OOM issue, there is no insight into which sub-bench failed. The failure will generally just look like `75/153 Test #9: bench_sanity_check ...................***Failed 770.84 sec out of memory`
* Places that can't use ctest (like the Windows-cross CI task) have to explicitly run it, or risk forgetting to run it.
* All benchmarks are run sequentially, when they could run in parallel instead.
Both issues can lead to CI timeouts and leave CPU unused during testing.
Fix all issues by running it as part of the functional tests instead. This is similar to the rpcauth tests (https://github.com/bitcoin/bitcoin/pull/32881) and util tests [bitcoin-tx, and bitcoin-util] (https://github.com/bitcoin/bitcoin/pull/32697).

Pull request description:
This PR deprecates the "startingheight" result field of the `getpeerinfo` RPC, following the discussion in #33990.
Rationale: the reported starting height of a peer in the VERSION message is untrusted, and it doesn't seem to be useful anymore (after #20624), so deprecating the corresponding field seems reasonable. After that, it can be removed, along with the `m_starting_height` field of the Peer / CNodeStats structs, as it is sufficient to show the reported height only once at connection in the debug log.

With the new SFL algorithm, the process of loading an existing linearization into the
SFL state is very similar to what PostLinearize does. This means there is little benefit
to performing an explicit PostLinearize step before linearizing inside txgraph. Instead,
it seems better to use our allotted CPU time to perform more SFL optimization steps.
With the SFL algorithm, we will practically be capable of keeping
most if not all clusters optimal. With that, it seems less valuable
to avoid doing work after splitting an acceptable cluster, because by
doing some work we may get it to OPTIMAL.
This reduces the complexity of the code a bit as well.
Introduce a new method intended to replace getCoinbaseRawTx(), which
provides a struct with everything clients need to construct a coinbase.
This is safer than providing a raw dummy coinbase that clients then have
to manipulate.
The CoinbaseTx data is populated during the dummy transaction generation
and stored in struct CBlockTemplate.
Expand the interface_ipc.py functional test to document its usage
and ensure equivalence.
The reported starting height of a peer in the VERSION message is
untrusted, and it doesn't seem to be useful anymore (after #20624),
so deprecating the corresponding "startingheight" field seems

6da6f503a6dd8de85780ca402f5202095aa8b6ea refactor: Let CCoinsViewCache::BatchWrite return void (TheCharlatan)
Pull request description:
CCoinsViewCache::BatchWrite always returns true if called from a backed cache, so just return void instead. Also return void from ::Sync and ::Flush.
This allows for dropping a FatalError condition and simplifying some dead error handling code a bit.
Since we now no longer exercise the "error path" when returning from `CCoinsView::BatchWrite`, make the method clear the cache instead. This should only be exercised by tests and not change production behaviour. This might slightly improve the coins_view fuzz test's ability to generate better coverage.

592157b7594693da389e4bd9b2cdedbdba7556fc test: move SEQUENCE_LOCKTIME flags to script (Sjors Provoost)
Pull request description:
[BIP 379](https://github.com/bitcoin/bips/blob/master/bip-0379.md) ([Miniscript](https://bitcoin.sipa.be/miniscript/)) allows relative height and time locks that have no consensus meaning in [BIP 68](https://github.com/bitcoin/bips/blob/master/bip-0068.mediawiki) (relative timelocks) / [BIP 112](https://github.com/bitcoin/bips/blob/master/bip-0112.mediawiki) (`CHECKSEQUENCEVERIFY`). This is (ab)used by some protocols, e.g. [by Lightning to encode extra data](https://delvingbitcoin.org/t/exploring-extended-relative-timelocks/1818/23), but is unsafe when used unintentionally: `older(65536)` is equivalent to `older(1)`.
This PR emits a warning when `importdescriptors` contains such a descriptor.
The first commit makes `SEQUENCE_LOCKTIME` flags reusable by other tests.
The main commit adds the `ForEachNode` helper to `miniscript.h` which is then used in the `MiniscriptDescriptor` constructor to check for `Fragment::OLDER` with unsafe values. These are stored in `m_warnings`, which the RPC code then collects via `Warnings()`.
It adds both a unit and functional test.
---
A previous version of this PR prevented the import, unless the user opted in with an `unsafe` flag. It also used string parsing in the RPC code.

fa66e2d07a4b87d62382a54acf5fab6af77be24e refactor: [rpc] Remove confusing and brittle integral casts (MarcoFalke)
Pull request description:
When constructing an UniValue from integral values, historically (long ago), in some cases casts where needed. With the current UniValue constructor, only very few are actually needed.
Keeping the unused casts around is:
* confusing, because code readers do not understand why they are needed
* brittle, because some may copy them into new places, where they will lead to hard-to-find logic bugs, such as the ones fixed in pull https://github.com/bitcoin/bitcoin/pull/34112
So fix all issues by removing them, except for a few cases, where casting was required:
* `ret.pushKV("coinbase", static_cast<bool>(coin->fCoinBase));`, or
* `static_cast<std::underlying_type_t<decltype(info.nServices)>>(info.nServices)`.
This hardening refactor does not fix any bugs and does not change any behavior.

44e006d4383155f254f908ada91c2d9a7a65db6c [kernel] Expose reusable PrecomputedTransactionData in script valid (Josh Doman)
Pull request description:
This PR exposes a reusable `PrecomputedTransactionData` object in script validation using libkernel.
Currently, libkernel computes `PrecomputedTransactionData` each time `btck_script_pubkey_verify` is called, exposing clients to quadratic hashing when validating a transaction with multiple inputs. By externalizing `PrecomputedTransactionData` and making it reusable, libkernel can eliminate this attack vector.
I discussed this problem in [this issue](https://github.com/TheCharlatan/rust-bitcoinkernel/issues/46). The design of this PR is inspired by @sedited's comments.
The PR introduces three new APIs for managing the `btck_PrecomputedTransactionData` object:

*
* @param[in] tx_to Non-null.
* @param[in] spent_outputs Nullable for non-taproot verification. Points to an array of

The PR also modifies `btck_script_pubkey_verify` so that it accepts `precomputed_txdata` instead of `spent_outputs`:
```c
/**
* @brief Verify if the input at input_index of tx_to spends the script pubkey
* under the constraints specified by flags. If the
* `btck_ScriptVerificationFlags_WITNESS` flag is set in the flags bitfield, the
* amount parameter is used. If the taproot flag is set, the precomputed data
* must contain the spent outputs.
*
* @param[in] script_pubkey Non-null, script pubkey to be spent.
* @param[in] amount Amount of the script pubkey's associated output. May be zero if
* the witness flag is not set.
* @param[in] tx_to Non-null, transaction spending the script_pubkey.
* @param[in] precomputed_txdata Nullable if the taproot flag is not set. Otherwise, precomputed data
* for tx_to with the spent outputs must be provided.
* @param[in] input_index Index of the input in tx_to spending the script_pubkey.
* @param[in] flags Bitfield of btck_ScriptVerificationFlags controlling validation constraints.
* @param[out] status Nullable, will be set to an error code if the operation fails, or OK otherwise.
* @return 1 if the script is valid, 0 otherwise.
*/
int btck_script_pubkey_verify(
const btck_ScriptPubkey* script_pubkey,
int64_t amount,
const btck_Transaction* tx_to,
const btck_PrecomputedTransactionData* precomputed_txdata,
unsigned int input_index,
btck_ScriptVerificationFlags flags,
btck_ScriptVerifyStatus* status) BITCOINKERNEL_ARG_NONNULL(1, 3);
```
As before, an error is thrown if the taproot flag is set and `spent_outputs` is not provided in `precomputed_txdata` (or `precomputed_txdata` is null). For simple single-input non-taproot verification, `precomputed_txdata` may be null, and the kernel will construct the precomputed data on-the-fly.
Both the C++ wrapper and the test suite are updated with the new API. Tests cover both `precomputed_txdata` reuse and nullability.
Appreciate feedback on this concept / approach!

Pull request description:
The logic for `DBHashKey` / `DBHeightKey` handling and lookup of entries is shared by `coinstatsindex` and `blockfilterindex`, leading to many lines of duplicated code. De-duplicate this by moving the logic to `index/db_key.h` (using templates for the index-specific `DBVal`).

e44dec027ceec2a5f74b65636689a51833d78a94 add release note about supporing non-TRUC <minrelay txns (Greg Sanders)
1488315d76ee40b9d021b7d0ecd01207eee4a426 policy: Allow any transaction version with < minrelay (Greg Sanders)
Pull request description:
Prior to cluster mempool, a policy was in place that
disallowed non-TRUC transactions from being
TX_RECONSIDERABLE in a package setting if it was below
minrelay. This was meant to simplify reasoning about mempool
trimming requirements with non-trivial transaction
topologies in the mempool. This is no longer a concern
post-cluster mempool, so this is relaxed.
In effect, this makes 0-value parent transactions relayable
through the network without the TRUC restrictions and
thus the anti-pinning protections.
