ecaa786cc1 rpc: add signet_challenge field to getblockchaininfo and getmininginfo (Ash Manning)
Pull request description:
Signet challenges are currently only available via `getblocktemplate` RPC.
`getblockchaininfo` and `getmininginfo` both provide inadequate information to distinguish signets. Since these are the RPCs used to determine the current network, they should also provide the signet challenge for signets.
Test coverage is included in `test/functional/feature_signet.py`.

5709718b83 coins: warn on shutdown for big UTXO set flushes (Lőrinc)
Pull request description:
Split out of https://github.com/bitcoin/bitcoin/pull/30611#issuecomment-2549027130
Setting a large `-dbcache` size postpones the index writes until the coins cache size exceeds the specified limit. This causes the final flush after manual termination to seemingly hang forever (e.g. tens of minutes for 20 GiB); Now that the `dbcache` upper cap has been lifted, this will become even more apparent, so a warning will be shown when large UTXO sets are flushed (currently >1 GiB), such as:
> 2024-12-18T18:25:03Z Flushed fee estimates to fee_estimates.dat.
> 2024-12-18T18:25:03Z [warning] Flushing large (1 GiB) UTXO set to disk, it may take several minutes
> 2024-12-18T18:25:09Z Shutdown: done
---
You can reproduce it by starting `bitcoind` with a large `-dbcache`:
> mkdir demo && cmake -B build -DCMAKE_BUILD_TYPE=Release && cmake --build build -j$(nproc) && build/src/bitcoind -datadir=demo **-dbcache=10000**
Waiting until the used memory is over 1 GiB
> 2024-12-18T18:25:02Z UpdateTip: [...] progress=0.069009 cache=**1181.1MiB**(8827981txo)
And cancelling the process from the terminal:
> ^C2024-12-18T18:25:03Z tor: Thread interrupt
> [...]
> 2024-12-18T18:25:03Z **[warning] Flushing large (1 GiB) UTXO set to disk, it may take several minutes*

ad224429f8 net: additional disconnection logging (Sjors Provoost)
Pull request description:
While debugging unexpected disconnections, possibly related to #28331, I found some additional [net] logging to be useful.
All cases where we disconnect now come with a log message that has the word `disconnecting`:
* all calls to `CloseSocketDisconnect()` log `disconnecting peer=…`
* wherever we set `pnode->fDisconnect = true;`
* for all `InactivityCheck` cases (which in turn sets `fDisconnect`)
* replaces "dropping" with "disconnecting" in `Network not active, dropping peer=…`
A few exceptions are listed here: https://github.com/bitcoin/bitcoin/pull/28521#discussion_r1890824361
I changed `CloseSocketDisconnect()` to no longer log `disconnecting`, and instead have all the call sites do so.
This PR introduces two helper functions on `CNode`: `DisconnectMsg` and `LogIP`. The second and third commit use these helpers in `net_processing.cpp` so these disconnect messages are more consistent now (e.g. some didn't log the IP). No new messages are added there though.
The `LogIP()` helper is rarely used outside of a disconnect event, but it's available for future use.
Any `LogPrint` this PR touches is replaced with `LogDebug` (superseded by #30750), and every `LogPrintf ` with `LogInfo`.

fadd568931 fuzz: Fix misplaced SeedRand::ZEROS (MarcoFalke)
Pull request description:
After commit fae63bf130 this must be placed even before test_setup. This is nice, because it makes the usage consistently appear in the first line.
The change is moving a `SeedRandomForTest(SeedRand::ZEROS)` to happen earlier. This is fine, because it will either have no effect, or make the code more deterministic, because after commit fae63bf, no other re-seeding other than `ZEROS` can happen in fuzz tests.

9a47852d88 Remove getTransactionsUpdated() from mining interface (Sjors Provoost)
bfc4e029d4 Remove testBlockValidity() from mining interface (Sjors Provoost)
Pull request description:
There are three methods in the mining interface that can be dropped. The Template Provider doesn't need them and other application should probably not use them either.
1. `processNewBlock()` was added in 7b4d3249ce, but became unnecessary with the introduction of interfaces::BlockTemplate::submitSolution in 7b4d3249ce.
Dropping it was suggested in https://github.com/bitcoin/bitcoin/pull/30200#issuecomment-2404460342
2. `getTransactionsUpdated()`: this is used in the implementation of #31003 `waitFeesChanged`. It's not very useful generically because the mempool updates very frequently.
3. `testBlockValidity()`: it might be useful for mining application to have a way to check the validity of a block template they modified, but the Stratum v2 Template Provider doesn't do that, and this method is a bit brittle (e.g. the block needs to build on the tip).

facb4d010c refactor: Move GuessVerificationProgress into ChainstateManager (MarcoFalke)
Pull request description:
Currently the function is standalone, which means any passed-in data like `TxData` or the block pointer needs to be taken from the `ChainstateManager` and passed in. This is currently verbose and may become even more verbose if the function is reworked in the future. As the function can not be called without a `ChainstateManager` in production code anyway, make it a member function on the class.

processNewBlock was added in 7b4d3249ce, but became unnecessary with the introduction of interfaces::BlockTemplate::submitSolution in 7b4d3249ce.
getTransactionsUpdated() is only needed by the implementation of waitFeesChanged() (not yet part of the interface).

Pull request description:
This is the first step toward improving fuzz stability and determinism (https://github.com/bitcoin/bitcoin/issues/29018).
A fuzz target using the global test-only PRNG will now abort if the seed is re-used across fuzz inputs.
Also, temporarily add `SeedRandomStateForTest(SeedRand::ZEROS)` to all affected fuzz targets. This may slow down the libfuzzer leak detector, but it will disable itself after some time, or it can be disabled explicitly with `-detect_leaks=0`.
In a follow-up, each affected fuzz target can be stripped of the global random use and a local `RandomMixin` (or similar) can be added instead.
(Can be tested by removing any one of the re-seed calls and observing a fuzz abort)

Pull request description:
Providing a script for the coinbase transaction is only done in test code and for (unoptimized) CPU solo mining.
Production miners use the `getblocktemplate` RPC which omits the coinbase transaction entirely from its block template, leaving it to external (pool) software to construct it.
This commit removes the `script_pub_key argument` from `createNewBlock()` in the Mining interface.
A coinbase script can still be passed via `BlockCreateOptions` instead. Tests are modified to do so.

To avoid future code changes from reintroducing the ambiguity fixed
by the previous commit, mark m_tip_block private and Assume that
it's not set to uint256::ZERO.
Belt and suspenders for future code changes.
Currently this function is only called from TransactionMerklePath() which sets leaves to the block transactions, so the Assume always holds.
The TARGET_OBJECTS generator expression was introduced in the staging
branch when we aimed to build the libbitcoinconsensus shared library.
However, `bitcoin_consensus` is a STATIC library, not an OBJECT library.
This change updates the build system to link `bitcoin_consensus`
normally to `test_bitcoin`, resolving linking issues when building with
clang-cl.
The variable is conditionally assigned toward the end of the loop and
not used after. It's then set back to its default value at the beginning
of the loop.

0e2b12b92a net, init: derive default onion port if a user specified a -port (Martin Zumsande)
Pull request description:
This resolves#31133 (setups with multiple local nodes each using a different `-port` no longer working with v28.0, see the issue description for more details) by deriving the default onion listening port to be the value specified by `-port` incremented by 1 (idea by vasild / laanwj).
Note that with this fix, the chosen `-port` values of two local nodes cannot be adjacent, otherwise there will be port collisions again.
From the discussion in the linked issue, this was the most popular option, followed by doing nothing and telling affected users to change their setups to use `-bind` instead of `-port`. But more opinions are certainly welcome!
I think that if we decide to do something about the problem described in the issue, we should do so soon (in 28.1.), so I opened this PR.

62b2d23edb wallet: Migrate non-HD keys to combo() descriptor (Ava Chow)
Pull request description:
Non-HD keys do not have an HD seed ID associated with them, so if this value is the null value (all 0s), then we should not perform any seed ID comparison that would result in excluding the keys from combo() migration.
This changes the migration of non-HD wallets (or blank wallets with imported private keys) to make a single combo() descriptors for the non-HD/imported keys, rather than pk(), pkh(), sh(wpkh()), and wpkh() descriptors for the keys.

Non-HD keys in legacy wallets without a HD seed ID were being migrated
to separate pk(), pkh(), sh(wpkh()), and wpkh() descriptors for each key.
These could be more compactly represented as combo() descriptors, so
migration should make combo() for them.
It is possible that existing non-HD wallets that were migrated, or
wallets that started blank and had private keys imported into them have
run into this issue. However, as the 4 descriptors produce the same output
scripts as the single combo(), so any previously migrated wallets are
not missing any output scripts. The only observable difference should be
performance related, and the wallet size on disk.

932cd1e92b wallet: fix crash during watch-only wallet migration (furszy)
Pull request description:
The crash occurs because we assume the cached scripts structure will not be empty,
but it can be empty for watch-only wallets that start blank.
This also adds test coverage for standalone imported keys, which were also crashing
because pubkey imports are treated the same way as hex script imports through
`importaddress()`.
Testing Notes:
This can be verified by cherry-picking and running any of the test commits on master.
It will crash there but pass on this branch.
