Merge #15226: Allow creating blank (empty) wallets (alternative)
7687f7873 [wallet] Support creating a blank wallet (Andrew Chow)

Pull request description:

  Alternative (kind of) to #14938

  This PR adds a `blank` parameter to the `createwallet` RPC to create a wallet that has no private keys initially. `sethdseed` can then be used to make a clean wallet with a custom seed. `encryptwallet` can also be used to make a wallet that is born encrypted.

  Instead of changing the version number as done in #14938, a wallet flag is used to indicate that the wallet should be blank. This flag is set at creation, and then unset when the wallet is no longer blank. A wallet becomes non-blank when a HD seed is set or anything is imported. The main change to create a blank wallet is primarily taken from #14938.

  Also with this, the term "blank wallet" is used instead of "empty wallet" to avoid confusion with wallets that have balance which would also be referred to as "empty".

  This is built on top of #15225 in order to fix GUI issues.

7687f7873b [wallet] Support creating a blank wallet
A blank wallet is a wallet that has no keys, script or watch only things.
A new wallet flag indicating that it is blank will be set when the wallet
is blank. Once it is no longer blank (a seed has been generated, keys or
scripts imported, etc), the flag will be unset.

Merge #14897: randomize GETDATA(tx) request order and introduce bias toward outbound
1cff3d6cb0 Change in transaction pull scheduling to prevent InvBlock-related attacks (Gleb Naumenko)

Pull request description:

  This code makes executing two particular (and potentially other) attacks harder.

  ### InvBlock
  This behavior was described well [here](https://www.cs.umd.edu/projects/coinscope/coinscope.pdf) (page 11).

  Per current implementation, if node A receives _INV_ (tx) from node B, node A sends _GETDATA_ to B and waits for _TX_ message back.

  Node A is likely to receive more _INVs_ (regarding the same tx) from other peers. But node A would not send another _GETDATA_ unless it does not hear _TX_ back from node B for next 2 minutes (to save bandwidth)

  Thus, if B is a malicious node, it can prevent node A from getting the transaction (even if all A’s peers have it) for 2 minutes.

  This behavior seems to be an inherent limitation of the current P2P relay protocol, and I don’t see how it can be fundamentally changed (I can see workarounds which involve rewriting a lot of P2P code though).

  ### What does this PR fix?

  The attacks I’m looking at involve preventing A from learning the transaction for 2*N minutes. To do that, an attacker has to spin up N nodes and send N _INVs_ simultaneously to node A (then InvBlocks will be queued with an interval of 2 minutes according to current implementation)

  More precisely, 2 scenarios I’m looking at are:
  1. An attacker censors a particular transaction. By performing InvBlock from different nodes, an attacker can execute a network-wide censorship of a particular transaction (or all transactions). The earlier an attacker founds the transaction he wants to censor, the easier it is to perform an attack. As it was pointed out by @gwillen, this is even more dangerous in the case of lightning, where transactions are known in advance.
  2. Topology inference described in papers [1](https://www.cs.umd.edu/projects/coinscope/coinscope.pdf), [2](https://arxiv.org/pdf/1812.00942.pdf) involve network-wide InvBlock. This fix would not mitigate this type of inference, but I believe it will make it more expensive to perform (an attacker would have to create more transactions and perform more rounds to learn the topology, the second paper itself notes that InvBlock isolation is important for the attack).

  ### How does it work
  This PR introduces bias toward outbound connections (they have higher priority when a node chooses from whom it should request a transaction) and randomizes the order.
  As per @gmaxwell suggestion, GETDATA requests queue is created after processing all incoming messages from all nodes.

  After this fix, if the incoming messages were [I1, I2, I3, O1, O2, O3, O4], the queue for _GETDATA_ may look like [O2, O1, O3, O4, I1, I3, I2, ….].

  If {I1, I2, I3} were significantly earlier (but the difference is less than TX_TIMEOUT=60 s) than others, the queue for _GETDATA_ may look like [I2, O2, O1, O3, O4, I1, I3, ….].

  ### Other comments:
  1. This mitigation works better if the connectivity is higher (especially outbound, because it would be less likely that 2 _GETDATAs_ for inbound malicious nodes queued together)

Pull request description:

  ~~Based on #14454 #14565, last two commits only are for review.~~

  Best reviewed with `?w=1`

  Allows a descriptor to be imported into the wallet using `importmulti` RPC. Start and end of range can be specified for ranged descriptors. The descriptor is implicitly converted to old structures on import.

  Also adds a simple test of a P2SH-P2WPKH address being imported as a descriptor. More tests to come, as well as release notes.

Merge #14667: Add deriveaddresses RPC util method
595283851 [rpc] util: add deriveaddresses method (Sjors Provoost)

Pull request description:

  Usage:

  ```sh
  bitcoin-cli deriveaddresses "wpkh([d34db33f/84h/0h/0h]xpub6DJ2dNUysrn5Vt36jH2KLBT2i1auw1tTSSomg8PhqNiUtx8QX2SvC9nrHu81fT41fvDUnhMjEzQgXnQjKEu3oaqMSzhSrHMxyyoEAmUHQbY/0/0)"
  [
    "bc1qg6ucjz7kgdedam7v5yarecy54uqw82yym06z3q"
  ] // part of the BIP32 test vector
  ```

  Avoids the need for external (BIP32) libraries to derive an address. Can be used in conjunction with `scantxoutset` as a poor mans wallet. Might be useful to test more complicated future descriptors.

  ~To keep it as simple as possible it only supports descriptors that result in a single address, so no `combo()` and ranges.~

  As discussed recently on IRC it might make sense to put this in a separate utility along with other descriptor and psbt utility functions which don't need a chain or wallet context. However I prefer to leave that to another PR.

Pull request description:

  Update the block and header tip is constraint to have a minimal distance of 250ms between updates... which can lead to miss the last header update.

  The modal overlay then assumes we are still in header sync and the view get stuck in "syncing headers,..." (while it's actually syncing blocks).

  This removes the 250ms minimal delta for header updates as well as it fixes the correct display of how header updates should update the labels.

Merge #15266: memory: Construct globals on first use
77777c5624 log: Construct global logger on first use (MarcoFalke)

Pull request description:

  The (de)initialization order is not well defined in C++, so generally it is not safe to use globals as the (de/con)structor of one global could use the (de/con)structor of another global before/after it has been (con/de)structed.

  Specifically this fixes:
  * `g_logger` might not be initialized on the first use, so do that. (Fixes #15111)

0dd6a8c124 Check m_internals in UnregisterValidationInterface
When a wallet is created it is registered in the validation interface (in
CWallet::CreateWalletFromFile) but it is not immediately added to the
wallets list. If a shutdown is requested before AddWallet (case more
evident when -rescan is set) then m_internals can be released (in
Shutdown -> UnregisterBackgroundSignalScheduler) before the wallet and
then ReleaseWallet would call UnregisterValidationInterface with
m_internals already released.

Merge #15263: Descriptor expansions only need pubkey entries for PKH/WPKH
11e0fd8d6 Descriptor expansions only need pubkey entries for PKH/WPKH (Pieter Wuille)

Pull request description:

  Currently, calling `Expand` on a `Descriptor` object will populate the output FlatSigningProvider with all public keys involved in the descriptor. This is overkill, as pubkey entries are only needed when the lookup of a public key based on its hash is desired (which is the case for `pkh`, `wpkh`, and `combo` descriptors).

  Fix this by pushing the population of pubkey entries down into the individual descriptor implementation's `MakeScript` function, instead of doing it generically.

  This should make it easier to implement #14491 without importing P2PKH outputs for the individual public keys listed inside a multisig.

  Fixes a bug where private keys could be imported to wallets with private keys disabled.

Also added an belt-and-suspenders check to `AddKeyPubkeyWithDB` to have it assert that the wallet has private keys enabled.

Pull request description:

  Instead of adding BerkeleyEnvironment objects permanently to the g_dbenvs map, use reference counted shared pointers and remove map entries when the last BerkeleyEnvironment reference goes out of scope.

  This change was requested by @TheBlueMatt and makes code that sets up mock databases cleaner. The mock database environment will now go out of scope and be reset on destruction so there is no need to call BerkeleyEnvironment::Reset() during wallet construction to clear out prior state.

  This change does affect bitcoin behavior slightly. On startup, instead of same wallet environments staying open throughout VerifyWallets() and OpenWallets() calls, VerifyWallets() will open and close an environment once for each wallet, and OpenWallets() will create its own environment(s) later.

Pull request description:

  Adds an offline tool `bitcoin-wallet-tool` for wallet creation and maintenance.

  Currently this tool can create a new wallet file, display information on an existing wallet, and run the salvage and zapwallettxes maintenance tasks on an existing wallet. It can later be extended to support other common wallet maintenance tasks.

  Doing wallet maintenance tasks in an offline tool makes much more sense (and is potentially safer) than having to spin up a full node.

Merge #15225: GUI: Change the receive button to respond to keypool state changing
2bc4c3eaf9 Notify the GUI that the keypool has changed to set the receive button (Andrew Chow)
14bcdbe09c Check for more than private keys disabled to show receive button (Andrew Chow)

Pull request description:

  Currently the Receive button in the GUI is displayed enabled or disabled by the initial state of the wallet when the wallet is first loaded. The button is only enabled or disabled depending on whether the disable private keys flag is set when the wallet is loaded. However, future changes to the wallet means that this initial state and check may no longer be accurate. #14938 introduces empty wallets which do not have private keys. An empty wallet that is loaded should have the Receive button disabled, and then it should become enabled once `sethdseed` is used so that a keypool can be generated and new keys generated. Likewise, with #14075, a wallet can be loaded with no keypool initially, so the button should be disabled. Later, public keys can be imported into the keypool, at which time the button should become enabled. When the keypool runs out again (no new keys are generated as the keypool only consists of imports), the button should become disabled.

  This PR makes it so that the button becomes enabled and disabled as the keypool state changes. The check for whether to enable or disable the receive button has changed to checking whether it is possible to get new keys. It now checks for whether the wallet has an HD seed and, if not, whether the private keys are disabled. When an action happens which would make it possible for a new address to be retrieved or make it possible for a no more addresses to be retrieved, a signal is emitted which has the GUI recheck the conditions for the Receive button. These actions are setting a new HD seed, topping up the keypool, retrieving a key from the keypool, and returning a key to the keypool.

Merge #15043: test: Build fuzz targets into seperate executables
2ca632e5b4 test: Build fuzz targets into seperate executables (MarcoFalke)
fab4bed68a [test] fuzz: make test_one_input return void (MarcoFalke)

Pull request description:

  Currently our fuzzer is a single binary that decides on the first few bits of the buffer what target to pick. This is ineffective as the fuzzer needs to "learn" how the fuzz targets are organized and could get easily confused. Not to mention that the (seed) corpus can not be categorized by target, since targets might "leak" into each other. Also the corpus would potentially become invalid if we ever wanted to remove a target...

  Solve that by building each fuzz target into their own executable.

Merge #15163: Correct units for "-dbcache" and "-prune"
6f6514a080 Correct units for "-dbcache" and "-prune" (Hennadii Stepanov)

Pull request description:

  Actually, all `dbcache`-related values in the code are measured in MiB (not in megabytes, MB) or in bytes (e.g., `nTotalCache`).

  See: https://github.com/bitcoin/bitcoin/blob/master/src/txdb.h

  ba8c8b2227/src/init.cpp (L1405-L1424)

  Also, "-prune" is fixed:
  1. The GUI values in GB are translated to the node values in MiB correctly.
  2. The maximum of the "prune" `QSpinBox` is not limited by default value of 99 (GB).

  Fix: #15106

Pull request description:

  This was probably accidentally added to the wrong line when addressing the feedback here: https://github.com/bitcoin/bitcoin/pull/7061#discussion_r142199778

  I already added the default values in #14877, but it could be clarified more that this really has no specific block height as default value, since the tip can change during a rescan.

Merge #14711: Remove uses of chainActive and mapBlockIndex in wallet code
44de1561a Remove remaining chainActive references from CWallet (Russell Yanofsky)
db21f0264 Convert CWallet::ScanForWalletTransactions and SyncTransaction to the new Chain apis (Russell Yanofsky)

700c42b85 Add height, depth, and hash methods to the Chain interface (Russell Yanofsky)

Pull request description:

  This change removes uses of `chainActive` and `mapBlockIndex` globals in wallet code. It is a refactoring change which does not affect external behavior.

  This is the next step in the larger #10973 refactoring change, which removes all other accesses to node global variables from wallet code. Doing this is useful to provide a better defined interface between the wallet and node, and necessary to allow wallet and node code to run in separate processes in #10102.

Merge #14929: net: Allow connections from misbehavior banned peers
0297be61a Allow connections from misbehavior banned peers. (Gregory Maxwell)

Pull request description:

  This allows incoming connections from peers which are only banned
   due to an automatic misbehavior ban if doing so won't fill inbound.

  These peers are preferred for eviction when inbound fills, but may
   still be kept if they fall into the protected classes.  This
   eviction preference lasts the entire life of the connection even
   if the ban expires.

  If they misbehave again they'll still get disconnected.

  The main purpose of banning on misbehavior is to prevent our
   connections from being wasted on unhelpful peers such as ones
   running incompatible consensus rules.  For inbound peers this
   can be better accomplished with eviction preferences.

  A secondary purpose was to reduce resource waste from repeated
   abuse but virtually any attacker can get a nearly unlimited
   supply of addresses, so disconnection is about the best we can
   do.

  This can reduce the potential from negative impact due to incorrect misbehaviour bans.
