Pull request description:
This PR rewrites the implementation of the BnB coinselection algorithm
to skip the duplicate evaluation of previously visited input selections.
In the original implementation of BnB, the state of the search is
backtracked by explicitly walking back to the omission branch and then
testing again. This retests an equivalent candidate set as before, e.g.,
after backtracking from {ABC}, it would evaluate {AB_}, before trying
{AB_D}, but {AB_} is equivalent to {AB} which was tested before.
CoinGrinder tracks the state of the search instead by remembering which
UTXO was last added and explicitly shifting from that UTXO directly to
the next, so after {ABC}, it will immediately move on to {AB_D}. We
replicate this approach here.
As fewer nodes are visited, this approach will enumerate more possible
combinations than the original implementation given the same limit for
iterations.

df7ed5f355 chainparams: encapsulate deployment configuration logic (Antoine Poinsot)
Pull request description:
It's sometimes useful to test a deployment on other networks than regtest. This may be e.g. because regtest lacks a property relevant for the test, or simply because the test aims to be portable while regtest is Bitcoin Core specific.
This PR makes it possible to set the `-vbparams` and `-testactivationheight` options on any network in unit tests, and on any **test** network as a startup option.
This is preparatory work for a BIP 54 implementation, but may be useful separately.

Pull request description:
This implements https://github.com/bitcoin/bips/pull/2116, which repurposes 24 version bits as extra nonce space for miners rather than soft fork deployment coordination. 24 bits allows a miner to perform up to 72 PH before needing a fresh job from its controller. The current 16 bits in use by miners only allow up to 280 TH, which [apparently led some ASIC designers to start rolling the timestamp field](https://github.com/bitaxeorg/ESP-Miner/pull/1553#issuecomment-3937736319) on their beefier machines.
Mailing list discussion available [here](https://gnusha.org/pi/bitcoindev/6fa0cb45-37d6-4b41-9ff8-03730fd96d6e@mattcorallo.com/). A previous shot at this is https://github.com/bitcoin/bitcoin/pull/13972 (with a smaller extranonce space).

8cb8653a22 fuzz: target concurrent leveldb reads (Andrew Toth)
6609088fe6 fuzz: extract ConsumeDBParams helper (Andrew Toth)
Pull request description:
Inspired by https://github.com/bitcoin/bitcoin/pull/31132#issuecomment-4054461591.
We currently do concurrent leveldb reads when accessing our indexes.
1. `txindex` - we call `FindTx()` from multiple RPC threads.
2. `blockfilterindex` - we call `LookupFilter/Header()` concurrently from `msghand` thread for p2p requests as well as RPC threads.
3. `coinstatsindex` - we call `LookUpStats()` from multiple RPC threads.
4. `txospenderindex` - we call `FindSpender()` from multiple RPC threads.
We also read from our chainstate and blocks index while background compactions are writing.
While OSS-Fuzz does cover leveldb (https://github.com/google/oss-fuzz/blob/master/projects/leveldb/fuzz_db.cc), it doesn't cover multi threaded access. Without a deterministic hypervisor this fuzz harness won't be deterministic, but we can at least run it with TSan to get a higher confidence that the synchronization code in leveldb is correct. Hopefully other reviewers find this useful.
This harness creates a threadpool with 16 threads, and then creates an in-memory levelDB which it seeds with deterministically random values. It chooses a random set of keys to query. It first performs all queries on the db on a single thread to get a baseline, then synchronizes all threads on a latch so they hit the db at the same time. Each thread performs the same queries, and afterwards are all checked against the baseline.
It uses a `DeterministicEnv` to capture background compaction work when seeding the db, which is also run immediately after the latch is released. This causes a race between compaction and reading, ensuring we exercise many thread synchronization code paths in leveldb.
I ran both TSan and ASan/UBSan overnight with no issues.

2ef6679c2c test: Check that MuSig2 signing does not reuse nonces (Ava Chow)
bb05986c0a musig: Include pubnonce in session id (Ava Chow)
Pull request description:
It is safe to have multiple musig signing sessions over the same message so long as the nonces used are different. Including the pubnonce in the session id allows for multiple simultaneous signing sessions over the same message, rather than asserting when the user tries to do this.
The second commit tests this behavior, both ensuring that there is no crash, and verifying that both sessions produce unique nonces and signatures to verify that no reuse is occurring.
Lastly, the assertion in `SetMuSig2SecNonce` is retained as hitting it now would indicate that a nonce has been reused. We prefer to assert and crash rather than do something that is highly likely to leak a private key.

c8b8c275fa test: Improve loopback address check in `rcp_bind.py` (xyzconstant)
Pull request description:
A [loopback address](https://www.geeksforgeeks.org/computer-networks/what-is-a-loopback-address/) can range from `127.0.0.0` to `127.255.255.255`. This commit relaxes the loopback check in `rpc_bind.py` by checking whether an IP address (from `all_interfaces()`) starts with `'127.'` instead of strictly matching `'127.0.0.1'`.
Programs like VPNs might add an extra loopback address (e.g., 127.1.130.83), which failed under the previous state. These addresses will now pass with this update.
---
**For context:** I found this while running tests with the Mullvad daemon active. Mullvad adds a custom lo0 interface like `inet 127.141.11.239 netmask 0xff000000` that failed with `--nonloopback`, which should not be the case since the address is a valid loopback IP.

131fa570b9 test: Add test for BuildSkip() and skip heights (optout)
Pull request description:
The skip height values computed by the (internal) function `GetSkipHeight()`, and the `CBlockIndex::BuildSkip()` method are not tested directly, and the skip logic is not well documented. To improve test coverage, a new test is added, to verify `CBlockIndex::BuildSkip()` and the skip height bit-manipulation logic.
Note: the original version contained a test for the complexity of the `GetAncestor()` algorithm, whose performance is greatly determined by the skip height logic. This test was out-scoped. (see: https://github.com/bitcoin/bitcoin/pull/33661#issuecomment-4486353485)
The motivation is to document the skip value computation through a test. (The issued was noticed while reviewing #33515.)

570a627640 kernel: assert invalid buffer preconditions in `btck_*_create` functions (stringintech)
Pull request description:
The kernel API appears to use `nullptr` returns to report failures that callers may reasonably want to recover from: malformed serialized input, object construction failures, chainstate/load failures, and similar runtime conditions.
The raw create-function buffer checks seem to be a different case. A failure of `ptr == nullptr && len > 0` does not indicate malformed input data or a failure encountered while deserializing or constructing the requested object. Returning `nullptr` for these checks widens the recoverable error surface with cases that are better treated as programmer errors, similar to other asserted preconditions in this API such as invalid indices and impossible enum/flag states.
This change switches those buffer argument checks from `nullptr` returns to assertions in `btck_transaction_create`, `btck_script_pubkey_create`, `btck_block_create`, `btck_block_header_create`, and `btck_chainstate_manager_options_create`. `btck_block_header_create` additionally asserts the pre-existing documented length contract (must be 80 bytes). These functions still return `nullptr` when the provided bytes cannot be parsed or when object creation fails during processing.
I ended up looking at this while working on the `kernel-bindings-tests` spec/schema for `btck_script_pubkey_create`, where treating this path as a regular error did not seem like the right contract: https://github.com/stringintech/kernel-bindings-tests/pull/14#discussion_r3240859568.

This fixes a small intermittent issue that snuck in via commit fa8d4d5c35.
Generally, it seems tedious and brittle trying to enumerate all possible exception types on all platforms and all test configs, all possible errno values, etc.
So just treat any `Exception` as crash, and confirm it in the test. The test would still fail, if a crash did not happen after an Exception, but the failure may be minimally more tedious to debug. I think this is fine, because failures should be rare and having simpler and more flexible test code is preferable.

Switch buffer `ptr == nullptr && len > 0` checks from `nullptr` returns to assertions.

After PR 28333, `LegacyDataSPKM` doesn't need to use the private or
protected members of `DescriptorScriptPubKeyMan` class such as
`AddDescriptorKeyWithDB` and `TopUpWithDB`. Moreover, these two SPKMs
are siblings that inherit from the common `ScriptPubKeyMan`.
It seems reasonable to me that they are unfriended so that private
members of one are not exposed to another unnecessarily.
In case locktime (and replaceable) not being specified in this RPC request,
the wallet sets the transaction replaceable due to the default value of opt-in
RBF set in the wallet.
This allowed the anti-fee-sniping flow to be executed but in case of
replaceable being set false in the request, anti-fee-sniping flow would be
missed.
This patch fixes it.
fedeff7f20 crypto: disable ASan instrumentation of SSE4 SHA256 for GCC (deadmanoz)
Pull request description:
Fix the runtime crash described in #34881.
Upstream already disables ASan instrumentation for `sha256_sse4::Transform()` under Clang. This extends the same workaround to GCC by adding an `#elif` branch for `__GNUC__` / `__SANITIZE_ADDRESS__` that applies the same `no_sanitize("address")` attribute.
Testing:
- reproduced the crash before the fix with GCC 13, 14, and 15 on Haswell-class machines / guests without SHA-NI (including by forcing the SSE4 implementation on GitHub CI)
- SEGV in debug builds regardless of optimization level (tested `-O0`, `-O1`, `-O2`, `-O3`)
- verified that the GCC + ASan debug configurations that previously crashed pass with this change
Issue #34881 has more details about the issue.
Note: the original Clang code placed the `__attribute__` between the function declarator and the opening brace. GCC's [Attribute Syntax](https://gcc.gnu.org/onlinedocs/gcc/Attribute-Syntax.html) documentation notes that this position in a function definition "may, in future, be permitted," so it is not currently supported. Placing the attribute at the start of the function definition is valid form for both GCC and Clang.

Pull request description:
Prerequisite to #35404 and #35405.
All these changes address the points raised in the review of PR #34917
here: https://github.com/bitcoin/bitcoin/pull/34917#pullrequestreview-4362148900.
Essentially updating the existing wallet functional tests without using
the -deprecatedrpc=bip125 and -walletrbf startup options. Instead,
these two are added and tested via a singular new
wallet_deprecated_rbf.py test that can be removed easily later when
these startup options are completely removed from the wallet post
deprecation.

Pull request description:
Instead of constructing ScriptPubKeyMans with no data, and then loading data as we find it, we should gather everything first and then load it all on construction. If there actually is no data and we want to setup generation, then that should also occur in a constructor rather than afterwards.
This change is only applied to DescriptorScriptPubKeyMan and ExternalSignerScriptPubKeyMan, and should be done for any ScriptPubKeyMans added in the future. I don't think it's really worth it to do this for LegacyScriptPubKeyMan since it would make loading performance worse (or cause layer violations) and it's (supposed to be) going away soon.

b86c1c443d test: add coverage for migrating ancient wallets (furszy)
fd44d48b24 wallet: fix ancient wallets migration (furszy)
Pull request description:
We currently fail migration if the wallet does not contain the best block locator.
This is a problem for wallets created before https://github.com/bitcoin/bitcoin/pull/152, which are not storing such record.
Missing this record is not an error. it simply means the wallet will scan the chain prior
to finish migration.

Switch runner and provider names over. We now use GHA cache, so we don't need to switch that over here.

fa51f37f18 doc: Reword the Getting-Started section (MarcoFalke)
fab5733f5d doc: Remove good_first_issue.yml (MarcoFalke)
Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/35399
IIUC, the good-first-issue label and template were meant to make it easier for completely new contributors to get started with something simple. However, I don't think the label and issue template are applicable anymore:
* There are currently no issues with this label, and directing people toward an empty list seems pointless.
* Historically the issue and label has been used rarely. 2026: once, 2025 twice, 2024 thrice. Source: https://github.com/bitcoin/bitcoin/issues?q=state%3Aclosed%20is%3Aissue%20label%3A%22good%20first%20issue%22
* The template has been mis-used, according to https://github.com/bitcoin/bitcoin/issues/35399
Fix all issues by removing it, since it is clear that it is no longer actively used, nor applicable and possibly a net-negative overall.
Of course, regular devs are still free to open issues of this kind as a normal issue, if they wish. However, having the template for this in this repo and tracking it via a label doesn't seem useful.
Since removing the template and label requires rewriting the "Getting Started" section in `CONTRIBUTING.md`, I went ahead and also removed the mention of `Up for grabs` as good things for newcomers to work on. I don't recall the last new contributor that picked something up successfully. Also, `Up for grabs` is usually stuff that people lost interest in, or is no longer relevant.
Instead I've added a sentence to encourage new contributors to help with critical and broad review, which will naturally guide them to good first follow-up issues to work on.
Meta: I know this topic can be subjective and offer bike-shed potential, but I am happy to iterate a bit on this for a few days.

3962138cc0 test: add IPC submitBlock functional test (woltx)
5b60f69e40 mining: add submitBlock IPC method to Mining interface (woltx)
813b4a80d7 refactor: introduce SubmitBlock helper (w0xlt)
Pull request description:
This PR adds a `submitBlock` method to the IPC Mining interface, equivalent to the `submitblock` RPC. It accepts a serialized block over IPC, validates/processes it via the normal block-processing path.
The method uses the same result shape as `checkBlock`: `bool` + `reason/debug out-params`. It reports duplicate, inconclusive, and invalid-block rejection details, and initializes reason/debug on every call.

Explain how to find good first issues to work on.
Also, remove the mention of up-for-grabs for new contributors, because
up-for-grabs is usually stuff that people lost interest in and is often
no longer relevant.
