5fc4939e17 Added static_assert to check that base_blob is using whole bytes. (Brotcrunsher)
Pull request description:
Prior to this commit it was possible to create base_blobs with any arbitrary amount of bits, like base_blob<9>. One could assume that this would be a valid way to create a bit field that guarantees to have at least 9 bits. However, in such a case, base_blob would not behave as expected because the WIDTH is rounded down to the closest whole byte (simple integer division by 8). This commit makes sure that this oddity is detected and blocked by the compiler.

Pull request description:
This (I believe) resolves the last of the blockers for [switching us away from cctools and instead using out-of-the-box llvm and lld](https://github.com/bitcoin/bitcoin/pull/21778) for building Darwin binaries.
For now, we continue building with a pre-packaged llvm and cctools, but after this PR the clang+lld combo should just work for anyone trying it. Additionally after this PR, the new runtime `fixup_chains` behavior will be in-use, as ld64 uses it as well.
The commits may seem unrelated, so in detail:
lld (llvm's linker) has been a work-in-progress for Darwin for years. Recently though, it has gained nearly all of the features we require. The last missing feature from ld64, `-Wl,-bind_at_load`, is not implemented in lld; as far as I can tell [lazy loading has conceptually been replaced by fixup chains](https://www.emergetools.com/blog/posts/iOS15LaunchTime).
So that means we don't need ld64's `bind_at_load` as long as lld can handle `-Wl,-fixup_chains` (which it can). I've added it to our configure as a linker option mostly so that we can see it in the logs; it's default-on as long as the minimum version is >11.0.
About that: the runtime functionality required for `-Wl,-fixup_chains` [requires macOS >=11.0](https://github.com/llvm/llvm-project/blob/release/16.x/lld/MachO/Driver.cpp#L1021). Hence the commit that bumps the minimum version. Our current min runtime of `10.15` has been unsupported since September 2022, so I don't expect this bump to be controversial.
Lastly, with the minimum runtime version bumped to 11.0, our current version of pre-compiled clang we use for macOS is too old to understand `-mmacosx-version-min=11.0` because it expects `=10.x`. So I've made the smallest possible bump (from 10.0.1 to 11.1.0) to a version that understands. This bump is arbitrary and unfortunate, but likely to be short-lived as we may end up replacing it with llvm+lld for v26 anyway. I've held off on bumping the SDK as I think that makes sense to do as part of the lld switch instead.

Pull request description:
This replaces #23432 and part of #23561.
This PR introduces all of the ElligatorSwift-related changes (libsecp256k1 updates, generation, decoding, ECDH, tests, fuzzing, benchmarks) needed for BIP324.
ElligatorSwift is a special 64-byte encoding format for public keys introduced in libsecp256k1 in https://github.com/bitcoin-core/secp256k1/pull/1129. It has the property that *every* 64-byte array is a valid encoding for some public key, and every key has approximately $2^{256}$ encodings. Furthermore, it is possible to efficiently generate a uniformly random encoding for a given public key or private key. This is used for the key exchange phase in BIP324, to achieve a byte stream that is entirely pseudorandom, even before the shared encryption key is established.

54877253c8 test: avoid sporadic MINIMALDATA failure in feature_taproot.py (fixes#27595) (Sebastian Falbesoner)
Pull request description:
The functional test feature_taproot.py fails in some rare cases on the execution of the following `"branched_codesep"` spending script (can be reproduced via `$ ./test/functional/feature_taproot.py --randomseed 9048710178866422833` on master / 137a98c5a2):
9d85c03620/test/functional/feature_taproot.py (L741)
The problem occurs if the first data-push (having random content with a random length in the range [0, 510]) has a length of 1 and the single byte has value of [1...16] or [-1]; in this case, the data-push is not minimally encoded by test framework's CScript class (i.e. doesn't use the special op-codes OP_1...OP_16 or OP_1NEGATE) and the script interpreter throws an SCRIPT_ERR_MINIMALDATA error:
```
test_framework.authproxy.JSONRPCException: non-mandatory-script-verify-flag (Data push larger than necessary) (-26)
```
Background: the functional test framework's CScript class translates passed bytes/bytearrays always to data pushes using OP_PUSHx/OP_PUSHDATA{1,2,4} op-codes (see `CScript.__coerce_instance(...)`). E.g. the expression `CScript(bytes([1]))` yields `bytes([OP_PUSH1, 1])` instead of the minimal-encoded `bytes([OP_1])`.
Fix this by adapting the random-size range to [2,...], i.e. never pass byte-arrays below length two to be pushed.
Closes#27595.

30778124b8 net: Give seednodes time before falling back to fixed seeds (Martin Zumsande)
Pull request description:
`-seednode` is an alternative bootstrap mechanism - when choosing it, we make a `AddrFetch` connection to the specified peer, gather addresses from them, and then disconnect. Presumably, if users specify a seednode they prefer addresses from that node over fixed seeds.
However, when disabling dns seeds and specifiying `-seednode`, `CConnman::ProcessAddrFetch()` immediately removes the entry from `m_addr_fetches` (before the seednode could give us addresses) - and once `m_addr_fetches` is empty, `ThreadOpenConnections` will add fixed seeds, resulting in a "race" between the fixed seeds and seednodes filling up AddrMan.
This PR suggests to check for any provided `-seednode` arg instead of using the size of `m_addr_fetches`, thus delaying the querying of fixed seeds for 1 minute when specifying any seednode (as we already do for `addnode` peers).
That way, we actually give the seednodes a chance for to provide us with addresses before falling back to fixed seeds.
This can be tested with `bitcoind -debug=net -dnsseed=0 -seednode=(...)` on a node without `peers.dat` and observing the debug log.

0e21b56a44 assumeutxo: catch and log fs::remove error instead of two exist checks (Andrew Toth)
Pull request description:
Fixes a block of code which seems to be incorrectly performing two existence checks instead of catching and logging errors. `fs::remove` returns `false` only if the file being removed does not exist, so it is redundant with the `fs::exists` check. If an error does occur when trying to remove an existing file, `fs::remove` will throw. See https://en.cppreference.com/w/cpp/filesystem/remove.
Also see https://github.com/bitcoin/bitcoin/blob/master/src/init.cpp#L326-L332 for a similar pattern.

1c7d08b9ac validation: Stricter assumeutxo error handling in InvalidateCoinsDBOnDisk (Ryan Ofsky)
9047337d36 validation: Stricter assumeutxo error handling in LoadChainstate (Ryan Ofsky)
Pull request description:
There are two places in assumeutxo code where it is calling `AbortNode` to trigger asynchronous shutdowns without returning errors to calling functions.
One case, in `LoadChainstate`, happens when snapshot validation succeeds, and there is an error trying to replace the background chainstate with the snapshot chainstate.
The other case, in `InvalidateCoinsDBOnDisk`, happens when snapshot validatiion fails, and there is an error trying to remove the snapshot chainstate.
In both cases the node is being forced to shut down, so it makes sense for these functions to raise errors so callers can know that an error happened without having to infer it from the shutdown state.
Noticed these cases while reviewing #27861, which replaces the `AbortNode` function with a `FatalError` function.

This replaces (but does not collide with) the previous bind_on_load. There
is technically no need to opt-in to this functionality as long as >= MacOS 11.0
is being targetted, but it will be helpful to see in the logs.
Unfortunately clang 10 does not understand "-mmacosx-version-min=11.0",
as it expects to see only 10.x.
Bump minimally to 11.1 to fix that problem. This will likely be our last
binary toolchain bump, as it will soon be replaced with usage of upstream
vanilla llvm.
61f4b9b7ad Manage exceptions in bcc callback functions (virtu)
Pull request description:
Address #27380 (and similar future issues) by handling failed `assert_equal()` assertions in bcc callback functions
### Problem
Exceptions are not propagated in ctype callback functions used by bcc. This means an AssertionError exception raised by `assert_equal()` to signal a failed assertion is not getting caught and properly logged. Instead, the error is logged to stdout and execution of the callback stops.
The current workaround to check whether all `assert_equal()` assertions in a callback succeeded is to increment a success counter after the assertions (which only gets incremented if none exception is raised and stops execution). Then, outside the callback, the success counter can be used to check whether a callback executed successfully.
One issue with the described workaround is that when an exception occurs, there is no way of telling which of the `assert_equal()` statements caused the exception; moreover, there is no way of inspecting how the pieces of data that got compared in `assert_equal()` differed (often a crucial clue when debugging what went wrong).
This problem is happening in #27380: Sporadically, in the `mempool:rejected` test, execution does not reach the end of the callback function and the success counter is not incremented. Thus, the test fails when comparing the counter to its expected value of one. Without knowing which of the asserts failed any why it failed, this issue is hard to debug.
### Solution
Two fixes come to mind. The first involves having the callback function make event data accessible outside the callback and inspecting the event using `assert_equal()` outside the callback. This solution still requires a counter in the callback in order to tell whether a callback was actually executed or if instead the call to perf_buffer_poll() timed out.
The second fix entails wrapping all relevant `assert_equal()` statements inside callback functions into try-catch blocks and manually logging AssertionErrors. While not as elegant in terms of design, this approach can be more pragmatic for more complex tests (e.g., ones involving multiple events, events of different types, or the order of events).
The solution proposed here is to select the most pragmatic fix on a case-by-case basis: Tests in `interface_usdt_net.py`, `interface_usdt_mempool.py` and `interface_usdt_validation.py` have been refactored to use the first approach, while the second approach was chosen for `interface_usdt_utxocache.py` (partly to provide a reference for the second approach, but mainly because the utxocache tests are the most intricate tests, and refactoring them to use the first approach would negatively impact their readability). Lastly, `interface_usdt_coinselection.py` was kept unchanged because it does not use `assert_equal()` statements inside callback functions.

e639364495 validation: add missing insert to m_dirty_blockindex (Martin Zumsande)
Pull request description:
When the status of a block index is changed, we must add it to `m_dirty_blockindex` or the change might not get persisted to disk.
This is missing from one spot in `FindMostWorkChain()`, where `BLOCK_FAILED_CHILD` is set.
Since we have [code](f0758d8a66/src/node/blockstorage.cpp (L284-L287)) that later sets missing `BLOCK_FAILED_CHILD` during the next startup, I don't think that this can lead to bad block indexes in practice, but I still think it's worth fixing.

1a572ce7d6 test: refactor: introduce `generate_keypair` helper with WIF support (Sebastian Falbesoner)
Pull request description:
In functional tests it is a quite common scenario to generate fresh elliptic curve keypairs, which is currently a bit cumbersome as it involves multiple steps, e.g.:
privkey = ECKey()
privkey.generate()
privkey_wif = bytes_to_wif(privkey.get_bytes())
pubkey = privkey.get_pubkey().get_bytes()
Simplify this by providing a new `generate_keypair` helper function that returns the private key either as `ECKey` object or as WIF-string (depending on the boolean `wif` parameter) and the public key as byte-string; these formats are what we mostly need (currently we don't use `ECPubKey` objects from generated keypairs anywhere).
With this, most of the affected code blocks following the pattern above can be replaced by one-liners, e.g.:
privkey, pubkey = generate_keypair(wif=True)
Note that after this commit, the only direct uses of `ECKey` remain in situations where we want to set the private key explicitly, e.g. in MiniWallet (test/functional/test_framework/wallet.py) or the test for the signet miner script (test/functional/tool_signet_miner.py).

fa76f0d0ef refactor: Make m_count_with_* in CTxMemPoolEntry int64_t, drop UBSAN supp (MarcoFalke)
Pull request description:
This is a refactor as long as no signed integer overflow appears. In normal operation and absent bugs, signed integer overflow should never happen in the touched code paths.
The main benefit of this refactor is to drop the file-wide ubsan suppression `unsigned-integer-overflow:txmempool.cpp`.
For now, this only changes the internal private representation and the publicly returned type remains `uint64_t`.

clang <=17 warns on -nostdlibinc, which causes an error on our -Werror builds.
Note that this breaks the "-fPIE" check in configure because it relies on
catching warnings, but that is not a problem for macOS.

a72af2e833 bench: disable birth time block skip for wallet_create_tx.cpp (furszy)
Pull request description:
As the benchmarks inside `wallet_create_tx.cpp` assert the wallet
balance at the end, they require all blocks to be scanned by the wallet.
So, we need to ensure that no blocks are skipped by the recently added
wallet birth time functionality.
This just means setting the wallet birth time to the genesis block time.
So the wallet is always older than any new block.
