Merge bitcoin/bitcoin#28207: mempool: Persist with XOR
fa6b053b5c mempool: persist with XOR (MarcoFalke)

Pull request description:

  Currently the `mempool.dat` file stores data received from remote peers as-is. This may be problematic when a program other than Bitcoin Core tries to interpret them by accident. For example, an anti-virus program or other program may scan the file and move it into quarantine, or delete it, or corrupt it.

  While the local wallet is expected to re-submit any pending transactions, unrelated transactions may be missing from the mempool after a restart. This may cause fee estimates to be off, or may cause block relay to be slower.

  Fix this, similar to https://github.com/bitcoin/bitcoin/pull/6650, by rolling a random XOR pattern over the dat file when writing or reading it.

  Obviously this can only protect against programs that accidentally and unintentionally are trying to mess with the dat file. Any program that intentionally wants to mess with the dat file can still trivially do so.

fada2f9110 refactor: Replace <filesystem> with <util/fs.h> (MarcoFalke)

Pull request description:

  Using `std::filesystem` is problematic:

  * There is a `fs` namespace wrapper for it. So having two ways to achieve the same is confusing.
  * Not using the `fs` wrapper is dangerous and buggy, because it disables known bugs by deleting problematic functions.

  Fix all issues by removing use of it and adding a linter to avoid using it again in the future.

Merge bitcoin/bitcoin#27935: fuzz: call lookup functions before calling Ban
fca0a8938e ci: remove "--exclude banman" for fuzzing in mac (brunoerg)
f9b286353f fuzz: call lookup functions before calling `Ban` (brunoerg)

Pull request description:

  Fixes #27924

  To not have any discrepancy, it's required to call lookup functions before calling `Ban`. If we don't do it, the assertion `assert(banmap == banmap_read);` may fail because `BanMapFromJson` will call `LookupSubNet` and cause the discrepancy between the banned and the loaded one. It happens especially in MacOS (#27924).

  Also, calling lookup functions before banning is what RPC `setban` does.

Pull request description:

  Motivation
  * It seems preferable to use stdlib data structures instead of boost if they can achieve close to the same thing.
  * Code external to mempool should ideally use its public helper methods instead of accessing `mapTx` or its iterators directly.
  * Reduce the number of complex boost multi index type interactions
  * Also see #28335 for further context/motivation. This PR together with #28385 simplifies that one.

  Overview of things done in this PR:
  * Make `vTxHashes` a vector of transaction references instead of a pair of transaction hash and iterator. The trade off here is that the data is retrieved on the fly with `GetEntry` instead of being cached in `vTxHashes`.
  * Introduce `GetEntry` helper method to replace the more involved `GetIter` where applicable
  * Replace `mapTx` access with `CTxMemPool` helper methods
  * Simplify `checkChainLimits` call in `node/interfaces.cpp`
  * Make `CTxMemPoolEntry`s `lockPoints`mutable such that they can be changed with a const iterator directly instead of going through `mapTx`
  * Make `BlockAssembler`'s `inBlock` and `failedTx` sets of transaction hashes.

5039c346ca init: completely remove `-zapwallettxes` (remaining hidden option) (Sebastian Falbesoner)

Pull request description:

  The `-zapwallettxes` functionality has been removed in v0.21.0 (see commit 3340dbadd3 / PR #19671), with the parameter being kept as hidden option, to inform users via an exit error that `abandontransaction` should be used instead.

  As any guides that still suggest to use `-zapwallettxes` would refer to a Bitcoin Core version that is EOL since many years (i.e. <= v0.20.x), it is highly unlikely that the error caused by the option is still relevant for any user, hence it seems fine to remove it now.

2574b7e177 net/rpc: Check all resolved addresses in ConnectNode rather than just one (Sergi Delgado Segura)

Pull request description:

  ## Rationale

  Currently, `addnode` has a couple of corner cases that allow it to either connect to the same peer more than once, hence wasting outbound connection slots, or add redundant information to `m_added_nodes`, hence making Bitcoin iterate through useless data on a regular basis.

  ### Connecting to the same node more than once

  In general, connecting to the same node more than once is something we should try to prevent. Currently, this is possible via `addnode` in two different ways:

  1. Calling `addnode` more than once in a short time period, using two equivalent but distinct addresses
  2. Calling `addnode add` using an IP, and `addnode onetry` after with an address that resolved to the same IP

  For the former, the issue boils down to `CConnman::ThreadOpenAddedConnections` calling `CConnman::GetAddedNodeInfo` once, and iterating over the result to open connections (`CConman::OpenNetworkConnection`) on the same loop for all addresses.`CConnman::ConnectNode` only checks a single address, at random, when resolving from a hostname, and uses it to check whether we are already connected to it.

  An example to test this would be calling:

  ```
  bitcoin-cli addnode "127.0.0.1:port" add
  bitcoin-cli addnode "localhost:port" add
  ```

  And check how it allows us to perform both connections some times, and some times it fails.

  The latter boils down to the same issue, but takes advantage of `onetry` bypassing the `CConnman::ThreadOpenAddedConnections` logic and calling `CConnman::OpenNetworkConnection` straightaway. A way to test this would be:

  ```
  bitcoin-cli addnode "127.0.0.1:port" add
  bitcoin-cli addnode "localhost:port" onetry
  ```

  ### Adding the same peer with two different, yet equivalent, addresses

  The current implementation of `addnode` is pretty naive when checking what data is added to `m_added_nodes`. Given the collection stores strings, the checks at `CConnman::AddNode()` basically check wether the exact provided string is already in the collection. If so, the data is rejected, otherwise, it is accepted. However, ips can be formatted in several ways that would bypass those checks.

  Two examples would be `127.0.0.1` being equal to `127.1` and `[::1]` being equal to `[0:0:0:0:0:0:0:1]`. Adding any pair of these will be allowed by the rpc command, and both will be reported as connected by `getaddednodeinfo`, given they map to the same `CService`.

  This is less severe than the previous issue, since even tough both nodes are reported as connected by `getaddednodeinfo`, there is only a single connection to them (as properly reported by `getpeerinfo`). However, this adds redundant data to `m_added_nodes`, which is undesirable.

  ### Parametrize `CConnman::GetAddedNodeInfo`
  Finally, this PR also parametrizes `CConnman::GetAddedNodeInfo` so it returns either all added nodes info, or only info about the nodes we are **not** connected to. This method is used both for `rpc`, in `getaddednodeinfo`, in which we are reporting all data to the user, so the former applies, and to check what nodes we are not connected to, in `CConnman::ThreadOpenAddedConnections`, in which we are currently returning more data than needed and then actively filtering using `CService.fConnected()`

Merge bitcoin/bitcoin#28785: validation: return more helpful results for reconsiderable fee failures and skipped transactions
1147e00e59 [validation] change package-fee-too-low, return wtxid(s) and effective feerate (glozow)
10dd9f2441 [test] use CheckPackageMempoolAcceptResult in previous tests (glozow)

5c786a026a [refactor] use Wtxid for m_wtxids_fee_calculations (glozow)

Pull request description:

  Split off from #26711 (suggested in https://github.com/bitcoin/bitcoin/pull/26711#issuecomment-1786392253). This is part of #27463.

  - Add 2 new TxValidationResults
    - `TX_RECONSIDERABLE` helps us encode transactions who have failed fee checks that can be bypassed using package validation. This is distinguished from `TX_MEMPOOL_POLICY` so that we re-validate a transaction if and only if it is eligible for package CPFP. In the future, we will have a separate cache for reconsiderable rejects so these transactions don't go in `m_recent_rejects`.
    - `TX_UNKNOWN` helps us communicate that we aborted package validation and didn't finish looking at this transaction: it's not valid but it's also not invalid (i.e. don't cache it as a rejected tx)
  - Return effective feerate and the wtxids of transactions used to calculate that effective feerate when the error is `TX_SINGLE_FAILURE`. Previously, we would only provide this information if the transaction passed. Now that we have package validation, it's much more helpful to the caller to know how the failing feerate was calculated. This can also be used to improve our submitpackage RPC result (which is currently a bit unhelpful when things fail).
  - Use the newly added `CheckPackageMempoolAcceptResult` for existing package validation tests. This increases test coverage and helps test the changes made in this PR.

Pull request description:

  This is joint work with amitiuttarwar.

  This has the first few commits of #28463. It is not strictly a prerequisite for that, but has changes that in our opinion make sense on their own.
  It improves the handling of maximum numbers for different connection types (that are set during init and don’t change after) by:
  * moving all calculations into one place, `CConnMan::Init()`. Before, they were dispersed between `Init`, `CConnman::Init` and other parts of `CConnman`, resulting in some duplicated test code.
  * removing the possibility of having a negative maximum of inbound connections, which is hard to argue about
  * renaming of variables and doc improvements

Merge bitcoin/bitcoin#26839: Add support for RNDR/RNDRRS for AArch64 on Linux
aee5404e02 Add support for RNDR/RNDRRS for aarch64 on Linux (John Moffett)

Pull request description:

  This checks whether the ARMv8.5-A optional TRNG extensions [RNDR](https://developer.arm.com/documentation/ddi0601/2022-12/AArch64-Registers/RNDR--Random-Number) and [RNDRRS](https://developer.arm.com/documentation/ddi0601/2022-12/AArch64-Registers/RNDRRS--Reseeded-Random-Number) are available and, if they are, uses them for random entropy purposes.

  They are nearly functionally identical to the x86 RDRAND/RDSEED extensions and are used in a similar manner.

  Currently, there [appears to be](https://marcin.juszkiewicz.com.pl/download/tables/arm-socs.html) only one actual hardware implementation -- the Amazon Graviton 3. (See the `rnd` column in the link.) However, future hardware implementations may become available.

  It's not possible to directly query for the capability in userspace, but the Linux kernel [added support](1a50ec0b3b) for querying the extension via `getauxval` in version 5.6 (in 2020), so this is limited to Linux-only for now.

  Reviewers may want to launch any of the `c7g` instances from AWS to test the Graviton 3 hardware. Alternatively, QEMU emulates these opcodes for `aarch64` with CPU setting `max`.

  Output from Graviton 3 hardware:

  ```
  ubuntu@ip:~/bitcoin$ src/bitcoind -regtest

  2023-01-06T20:01:48Z Default data directory /home/ubuntu/.bitcoin
  ```

  Graviton 2 (doesn't support extensions):

  ```

  ```

  This partially closes #26796. As noted in that issue, OpenSSL [added support](https://github.com/openssl/openssl/pull/15361) for these extensions a little over a year ago.

Pull request description:

  Move `GetServicesNames()` from `rpc/util` to `rpc/net.cpp`, as it is only called from that compilation unit and there is no reason for other ones to need it.

  Remove the `protocol.h` include in `rpc/util.h`, as it was only needed for `GetServicesNames()`, drop an unneeded forward declaration (the other IWYU suggestions would require more extensive changes in other files), and add 3 already-missing include headers in other translation units that are needed to compile without `protocol.h` in `rpc/util.h`, as `protocol.h` includes `netaddress.h`, which in turn includes `util/strencodings.h`.

Merge bitcoin/bitcoin#28649: Do the SOCKS5 handshake reliably
af0fca530e netbase: use reliable send() during SOCKS5 handshake (Vasil Dimov)
1b19d1117c sock: change Sock::SendComplete() to take Span (Vasil Dimov)

Pull request description:

  The `Socks5()` function which does the SOCKS5 handshake with the SOCKS5 proxy sends bytes to the socket without retrying partial writes.

  `send(2)` may write only part of the provided data and return. In this case the caller is responsible for retrying the operation with the remaining data. Change `Socks5()` to do that. There is already a method `Sock::SendComplete()` which does exactly that, so use it in `Socks5()`.

  A minor complication for this PR is that `Sock::SendComplete()` takes `std::string` argument whereas `Socks5()` has `std::vector<uint8_t>`. Thus the necessity for the first commit. It is possible to do also in other ways - convert the data in `Socks5()` to `std::string` or have just one `Sock::SendComplete()` that takes `void*` and change the callers to pass `str.data(), str.size()` or `vec.data(), vec.size()`.

  This came up while testing https://github.com/bitcoin/bitcoin/pull/27375.

f06016d77d wallet: Add asserts to detect unset transaction height values (Ryan Ofsky)
262a78b133 wallet, refactor: Add CWalletTx::updateState function (Ryan Ofsky)

Pull request description:

  Originally, this PR fixed a wallet migration bug that could cause the watchonly wallet created by legacy wallet migration to have incorrect transaction height values. A different fix for the bug was implemented in #28609, but that PR did not add any test coverage that would have caught the bug, and didn't include other changes from this PR intended to prevent problems from invalid transaction heights.

  This PR adds new asserts to catch invalid transaction heights, which would trigger test failures without bugfix in #28609. This PR also refactors code and adds comments to clarify assumptions and make it less likely a bug from invalid transaction height values would be introduced.

Merge bitcoin/bitcoin#28799: wallet: cache descriptor ID to avoid repeated descriptor string creation
5e6bc6d830 test: remove custom rpc timeout for `wallet_miniscript.py`, reorder in test_runner (Sebastian Falbesoner)
f811a24421 wallet: cache descriptor ID to avoid repeated descriptor string creation (Sebastian Falbesoner)

Pull request description:

  Right now a wallet descriptor is converted to its string representation (via `Descriptor::ToString`) repeatedly at different instances:
  - on finding a `DescriptorScriptPubKeyMan` for a given descriptor (`CWallet::GetDescriptorScriptPubKeyMan`, e.g. used by the `importdescriptors` RPC); the string representation is created once for each spkm in the wallet and at each iteration again for the searched descriptor (`DescriptorScriptPubKeyMan::HasWalletDescriptor`)
  - whenever `DescriptorScriptPubKeyMan::GetID()` is called, e.g. in `TopUp` or any instances where a descriptor is written to the DB to determine the database key, also at less obvious places like `FastWalletRescanFilter` etc.

  As there is no good reason to calculate a fixed descriptor's string/ID more than once, add the ID as a field to `WalletDescriptor` and calculate it immediately at initialization (or deserialization). `HasWalletDescriptor` is changed to compare the spkm's and searched descriptor's ID instead of the string to take use of that.

  This speeds up the functional test `wallet_miniscript.py` by a factor of 5-6x on my machine (3m30.95s on master vs. 0m38.02s on PR). The recently introduced "max-size TapMiniscript" test-case introduced a descriptor that takes 2-3 seconds to create a string representation, so the repeated calls to that were significantly hurting the performance.

  Fixes https://github.com/bitcoin/bitcoin/issues/28800.
