Merge #13926: [Tools] bitcoin-wallet - a tool for creating and managing wallets offline
3c3e31c3a4 [tests] Add wallet-tool test (João Barbosa)
49d2374acf [tools] Add wallet inspection and modification tool (Jonas Schnelli)

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.

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.

  The launch-at-startup API Bitcoin Core uses on macOS where removed in macOS 10.11 leading to a segmentation-fault due to the weak-linking when not actively compiled against SDK 10.11 (`-mmacosx-version-min=10.11`)

  This PR removes the launch-at-startup feature on macOS when compiled with macOS min version > 10.11 (the default is always the macOS version you compile on).

  **The depends built binaries (Gitian) are not affected since we are building with min macOS 10.10.**

  Users self compiling on macOS > 10.11 can re-enable the feature by compiling with min version <= 10.11 (`CXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" ./configure`)

  **Isn't there a new API from Apple?**
  Yes, [there is](https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPSystemStartup/Chapters/CreatingLoginItems.html).
  It will require to create a helper application which needs to be embedded in the .app folder (needs code signing as well). Developers willing to go down that rabbit hole are welcome.

  Fixes #15142

Gregory Maxwell 0297be61ac Allow connections from misbehavior banned peers.
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.

Merge #14906: refactor: Make explicit CMutableTransaction -> CTransaction conversion.
b301950df3  Made expicit constructor CTransaction(const CMutableTransaction &tx). (lucash-dev)
faf29dd019  Minimal changes to comply with explicit CMutableTransaction -> CTranaction conversion. (lucash-dev)

Pull request description:

  This PR is re-submission of #14156, which was automatically closed by github (glitch?)

  Original description:

  This PR makes explicit the now implicit conversion constructor `CTransaction(const CMutableTransaction&)` in `transaction.h`.
  Minimal changes were made elsewhere to make the code compilable. I'll follow up with other PRs to address individually refactoring functions that should have a `CMutableTransaction` version, or where a `CTransaction` should be reused.

  The rationale for this change is:

   - Conversion constructors should not be explicit unless there's a strong reason for it (in the opinion of, for example, https://google.github.io/styleguide/cppguide.html, and https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#Ro-conversion. Let me know your take on this).
   - This particular conversion is very costly -- it implies a serialization plus hash of the transaction.
   - Even though `CTransaction` and `CMutableTransaction` represent the same data, they have very different use cases and performance properties.
   - Making it explicit allows for easier reasoning of performance trade-offs.
   - There has been previous performance issues caused by unneeded use of this implicit conversion.
   - This PR creates a map for places to look for possible refactoring and performance gains (this benefit still holds if the PR is not merged).

Pull request description:

  This does not remove OpenSSL, but makes our own PRNG the 'main' one; for GetStrongRandBytes, the OpenSSL RNG is still used (indirectly, by feeding its output into our PRNG state).

  It includes a few policy changes (regarding what entropy is seeded when).

  Before this PR:
  * GetRand*:
    * OpenSSL
  * GetStrongRand*:
    * CPU cycle counter
    * Perfmon data (on Windows, once 10 min)
    * /dev/urandom (or equivalent)
    * rdrand (if available)
  * From scheduler when idle:
    * CPU cycle counter before and after 1ms sleep
  * At startup:
    * CPU cycle counter before and after 1ms sleep

  After this PR:
  * GetRand*:
    * Stack pointer (which indirectly identifies thread and some call stack information)
    * rdrand (if available)
    * CPU cycle counter
  * GetStrongRand*:
    * Stack pointer (which indirectly identifies thread and some call stack information)
    * rdrand (if available)
    * CPU cycle counter
    * /dev/urandom (or equivalent)
    * OpenSSL
    * CPU cycle counter again
  * From scheduler when idle:
    * Stack pointer (which indirectly identifies thread and some call stack information)
    * rdrand (if available)
    * CPU cycle counter before and after 1ms sleep
    * Perfmon data (on Windows, once every 10 min)
  * At startup:
    * Stack pointer (which indirectly identifies thread and some call stack information)
    * rdrand (if available)
    * CPU cycle counter
    * /dev/urandom (or equivalent)
    * OpenSSL
    * CPU cycle counter again
    * Perfmon data (on Windows, once every 10 min)

  The interface of random.h is also simplified, and documentation is added.

  This implements most of #14623.
