  ![bitcoin-qt](https://user-images.githubusercontent.com/762502/67396157-62f3d000-f5a7-11e9-8a6f-9425823fcd6c.gif)
  This PR is the third and final piece of the basic Android support puzzle - it depends on https://github.com/bitcoin/bitcoin/pull/16110 and is related to https://github.com/bitcoin/bitcoin/pull/16883. It introduces an `android` directory under `qt` and a simple way to build an Android package of `bitcoin-qt`:

  1. Build depends for Android as described in the [README](https://github.com/bitcoin/bitcoin/blob/master/depends/README.md)
  2. Configure with one of the resulting prefixes
  3. Run `make && make apk` in `src/qt`

  The resulting APK files will be in `android/build/outputs/apk`. You can install them manually or with [adb](https://developer.android.com/studio/command-line/adb). One can also open the `android` directory in Android Studio for that integrated development and debugging experience. `BitcoinQtActivity` is your starting point.

  Under the hood makefile `apk` target:

  1. Renames the `bitcoin-qt` binary to `libbitcoin-qt.so` and copies it over to a folder under `android/libs` depending on which prefix and corresponding [ABI](https://developer.android.com/ndk/guides/abis.html#sa) `bitcoin-qt` was built for
  2. Takes `libc++_shared.so` from the Android NDK and puts in the same place. It [must be included](https://developer.android.com/ndk/guides/cpp-support) in the APK
  3. Extracts Qt for Android Java support files from the `qtbase` archive in `depends/sources` to `android/src`

  There is also just a tiny bit of `ifdef`'d code to make the Qt Widgets menus usable. It's not pretty but it works and is a stepping stone towards https://github.com/bitcoin/bitcoin/pull/16883.

This has never worked with any of the mingw-w64 compilers we use, and
the -O0 is causing issues for builders applying spectre mitigations.

Recent discussion on https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90458

Merge #21007: bitcoind: Add -daemonwait option to wait for initialization
e017a913d0 bitcoind: Add -daemonwait option to wait for initialization (Wladimir J. van der Laan)
c3e6fdee6d shutdown: Use RAII TokenPipe in shutdown (Wladimir J. van der Laan)
612f746a8f util: Add RAII TokenPipe (Wladimir J. van der Laan)

Pull request description:

  This adds a `-daemonwait` flag that does the same as `-daemon` except that it, from a user perspective, backgrounds the process only after initialization is complete. This is similar to the behaviour of some other software such as c-lightning.

  This can be useful when the process launching bitcoind wants to guarantee that either the RPC server is running, or that initialization failed, before continuing. The exit code indicates the initialization result.

  The use of the libc function `daemon()` is replaced by a custom implementation which is inspired by the [glibc implementation](https://github.com/lattera/glibc/blob/master/misc/daemon.c#L44), but which also creates a pipe from the child to the parent process for communication.

  An additional advantage of having our own `daemon()` implementation is that no MACOS-specific pragmas are needed anymore to silence a deprecation warning.

  TODO:

  - [x] Factor out `token_read` and `token_write` to an utility, and use  them in `shutdown.cpp` as well—this is exactly the same kind of communication mechanism.

      - [x] RAII-ify pipe endpoints.

  - [x] Improve granularity of the `configure.ac` checks. This currently  still checks for the function `daemon()` which makes no sense as  it's not used. It should check for individual functions such as
    `fork()` and `setsid()` etc—the former being required, the second optional.

  - [-] ~~Signal propagation during initialization: if say, pressing Ctrl-C during `-daemonwait` it would be good to pass this SIGINT on to the child process instead of detaching the parent process and letting the child run free.~~ This is not necessary, see https://github.com/bitcoin/bitcoin/pull/21007#issuecomment-769007341.

  Future:

  - Consider if it makes sense to use this in the RPC tests (there would be no more need for "is RPC ready" polling loops). I think this is out of scope for this PR.

Merge #21250: build: make HAVE_O_CLOEXEC available outside LevelDB (bugfix)
9bac71350d build: make HAVE_O_CLOEXEC available outside LevelDB (bugfix) (Sebastian Falbesoner)
584fd91d2d init: only use pipe2 if availabile, check in configure (Sebastian Falbesoner)

Pull request description:

  The result of the O_CLOEXEC availability check is currently only set in the Makefile and passed to LevelDB (see `LEVELDB_CPPFLAGS_INT` in `src/Makefile.leveldb.include`), but not defined to be used in our codebase. This means that code within the preprocessor conditional `#if HAVE_O_CLOEXEC` was actually never compiled. On the master branch this is currently used for pipe creation in `src/shutdown.cpp`, PR #21007 moves this part to a new module (I found the issue while testing that PR).

  The fix is similar to the one in #19803, which solved the same problem for HAVE_FDATASYNC.

  In the course of working on the PR it turned out that pipe2 is not available an all platforms, hence a configure check and a corresponding define HAVE_PIPE2 is introduced and used.

  The PR can be tested by anyone with a system that has pipe2 and O_CLOEXEC available by putting gibberish into the HAVE_O_CLOEXEC block: on master, everything should compile fine, on PR, the compiler should abort with an error. At least that's my naive way of testing preprocessor logic, happy to hear more sophisticated ways :-)

Merge #21205: build: actually fail when Boost is missing
c5da2749e2 build: actually stop configure if Boost isn't available (fanquake)
cad8b527ea build: explicitly install libboost-dev package (fanquake)

Pull request description:

  If Boost is not found via AX_BOOST_BASE, we don't actually stop
  configuring, only a warning is emitted:
  ```bash
  checking for boostlib >= 1.58.0 (105800)... configure: We could not detect the boost libraries (version MINIMUM_REQUIRED_BOOST or higher). If you have a staged boost library (still not installed) please specify $BOOST_ROOT in your environment and do not give a PATH to --with-boost option.  If you are sure you have boost installed, then check your version number looking in <boost/version.hpp>. See http://randspringer.de/boost for more documentation.
  ```

  Instead we usually fail when one of the other AX_BOOST_* macros fails to find a library. These macros are slowly being
  removed, and in any case, it makes more sense to fail earlier if Boost is missing.

  If Boost is unavailable, the failure now looks like:
  ```bash
  checking for boostlib >= 1.58.0 (105800)... configure: We could not detect the boost libraries (version 1.58.0 or higher). If you have a staged boost library (still not installed) please specify $BOOST_ROOT in your environment and do not give a PATH to --with-boost option.  If you are sure you have boost installed, then check your version number looking in <boost/version.hpp>. See http://randspringer.de/boost for more documentation.
  configure: error: Boost is not available!
  ```

  Note that we now just pass the version into AX_BOOST_BASE, which fixes it's display in the output (rather than showing `MINIMUM_REQUIRED_BOOST`).

  This PR also has a commit that adds `libboost-dev` to our install instructions and CI. This package is currently installed as a side-effect of installing our other libboost-*-dev packages. However as those continue to disappear, it makes sense to install boost-dev explicitly.

build: remove mostly pointless BOOST_PROCESS macro
Performing a series of link checks for a Boost component that is
header-only doesn't make much sense, and currently means we just have
another confusing Boost macro in our tree. I'm not sure why this was
originally done this way; maybe Sjors or luke-jr can elaborate
(#15382 (929cda5470))?

The macro also has the side-effect of producing confusing error
messages. i.e in #20744, the CI is currently failing with:
```bash
checking for boostlib >= 1.58.0 (105800) lib path in "/tmp/cirrus-ci-build/depends/x86_64-pc-linux-gnu/lib"... yes
checking for boostlib >= 1.58.0 (105800)... yes
checking whether the Boost::Process library is available... yes
configure: error: Could not find a version of the Boost::Process library!
```

This isn't useful, given there is no such thing as a `Boost::Process`
library.

This PR just removes the macro entirely, but maintains a `--with-boost-process`
(defaulting to off), flag to configure. Hopefully this will also be
removed, in favour of `--enable-disable-external-signer` if/when #16546
is merged.

Pull request description:

  This replaces `boost::shared_mutex` and `boost::unique_lock` with [`std::shared_mutex`](https://en.cppreference.com/w/cpp/thread/shared_mutex) & [`std::unique_lock`](https://en.cppreference.com/w/cpp/thread/unique_lock).

  Even though [some concerns were raised](https://github.com/bitcoin/bitcoin/issues/16684#issuecomment-726214696) in #16684 with regard to `std::shared_mutex` being unsafe to use across some glibc versions, I still think this change is an improvement. As I mentioned in #21022, I also think trying to restrict standard library feature usage based on bugs in glibc is not only hard to do, but it's not currently clear exactly how we do that in practice (does it also extend to patching out use in our dependencies, should we be implementing more runtime checks for features we are using, when do we consider an affected glibc "old enough" not to worry about? etc). If you take a look through the [glibc bug tracker](https://sourceware.org/bugzilla/describecomponents.cgi?product=glibc) you'll no doubt find plenty of (active) bug reports for standard library code we already using. Obviously not to say we shouldn't try and avoid buggy code where possible.

  Two other points:

  [Cory mentioned in #21022](https://github.com/bitcoin/bitcoin/pull/21022#issuecomment-769274179):
  > It also seems reasonable to me to worry that boost hits the same underlying glibc bug, and we've just not happened to trigger the right conditions yet.

  Moving away from Boost to the standard library also removes the potential for differences related to Boosts configuration. Boost has multiple versions of `shared_mutex`, and what you end up using, and what it's backed by depends on:
  * The version of Boost.
  * The platform you're building for.
  * Which version of `BOOST_THREAD_VERSION` is defined: (2,3,4 or 5) default=2. (see [here](https://www.boost.org/doc/libs/1_70_0/doc/html/thread/build.html#thread.build.configuration) for some of the differences).
  * Is `BOOST_THREAD_V2_SHARED_MUTEX` defined? (not by default). If so, you might get the ["less performant, but more robust"](https://github.com/boostorg/thread/issues/230#issuecomment-475937761) version of `shared_mutex`.

  A lot of these factors are eliminated by our use of depends, but users will have varying configurations. It's also not inconceivable to think that a distro, or some package manager might start defining something like `BOOST_THREAD_VERSION=3`. Boost tried to change the default from 2 to 3 at one point.

  With this change, we no longer use Boost Thread, so this PR also removes it from depends, the build system, CI etc.

  Previous similar PRs were #19183 & #20922. The authors are included in the commits here.
  Also related to #21022 - pthread sanity checking.

Merge #20720: build: more robustly check for fcf-protection support
e9189a750b build: more robustly check for fcf-protection support (fanquake)

Pull request description:

  When using Clang 7, we may end up trying to use the flag when it won't
  work properly, which can lead to confusing errors. i.e:
  ```bash
  /usr/bin/ld: error: ... <corrupt x86 feature size: 0x8>
  ```

  Use `AX_CHECK_LINK_FLAG` & `--fatal-warnings` to ensure we wont use the flag in this case.

  We do this as even when the error is emitted, compilation succeeds, and the binaries produced will run. This means we can't just check if the compiler accepts the flag, or if compilation succeeds (without or without `-Werror`, and/or passing `-Wl,--fatal-warnings`, which may not be passed through to the linker).

  This was reported by someone configuring for fuzzing, on Debian 10, where Clang 7 is the default.

  See here for a minimal example of the problematic behaviour:

32cbb06676 build: build fuzz tests by default.
This fixes issue #19388. The changes are as follows:
  - Add a new flag to configure, --enable-fuzz-binary, which allows building test/fuzz/fuzz regardless of whether we are building to do actual fuzzing
  - Set -DPROVIDE_MAIN_FUNCTION whenever --enable-fuzz is no
  - Add the following libraries to FUZZ_SUITE_LD_COMMON:
    - LIBBITCOIN_WALLET
    - SQLLITE_LIBS
    - BDB_LIBS
    - if necessary, some or all of:
      - NATPMP_LIBS
      - MINIUPNPC_LIBS
      - LIBBITCOIN_ZMQ / ZMQ_LIBS

Merge #19866: eBPF Linux tracepoints
22eb7930a6 tracing: add tracing framework (William Casarin)
933ab8a720 build: detect sys/sdt.h for eBPF tracing (William Casarin)

Pull request description:

  Instead of writing ad-hoc logging everywhere (eg: #19509), we can take advantage of linux user static defined traces, aka. USDTs ( not the stablecoin 😅 )

  The linux kernel can hook into these tracepoints at runtime, but otherwise they have little to no performance impact. Traces can pass data which can be printed externally via tools such as bpftrace. For example, here's one that prints incoming and outgoing network messages:

  # Examples

  ## Network Messages

  ```
  #!/usr/bin/env bpftrace

  BEGIN
  {
    printf("bitcoin net msgs\n");
    @start = nsecs;
  }

  usdt:./src/bitcoind:net:push_message
  {
    $ip = str(arg0);
    $peer_id = (int64)arg1;
    $command = str(arg2);
    $data_len = arg3;
    $data = buf(arg3,arg4);
    $t = (nsecs - @start) / 100000;

    printf("%zu outbound %s %s %zu %d %r\n", $t, $command, $ip, $peer_id, $data_len, $data);

    @outbound[$command]++;
  }

  usdt:./src/bitcoind:net:process_message
  {
    $ip = str(arg0);
    $peer_id = (int64)arg1;
    $command = str(arg2);
    $data_len = arg3;
    $data = buf(arg3,arg4);
    $t = (nsecs - @start) / 100000;

    printf("%zu inbound %s %s %zu %d %r\n", $t, $command, $ip, $peer_id, $data_len, $data);

    @inbound[$ip, $command]++;
  }

  ```

      $ sudo bpftrace netmsg.bt

  output: https://jb55.com/s/b11312484b601fb3.txt

  if you look at the bottom of the output you can see a histogram of all the messages grouped by message type and IP. nice!

  ## IBD Benchmarking

  ```
  #!/usr/bin/env bpftrace
  BEGIN
  {
    printf("IBD to 500,000 bench\n");
  }

  usdt:./src/bitcoind:CChainState:ConnectBlock
  {
    $height = (uint32)arg0;

    if ($height == 1) {
      printf("block 1 found, starting benchmark\n");
      @start = nsecs;
    }

    if ($height >= 500000) {
      @end = nsecs;
      @duration = @end - @start;
      exit();
    }
  }

  END {
    printf("duration %d ms\n", @duration / 1000000)
  }
  ```
  This one hooks into ConnectBlock and prints the IBD time to height 500,000 starting from the first call to ConnectBlock

  Userspace static tracepoints give lots of flexibility without invasive logging code. It's also more flexible than ad-hoc logging code, allowing you to instrument many different aspects of the system without having to enable per-subsystem logging.

  Other ideas: tracepoints for lock contention, threads, what else?

  Let me know what ya'll think and if this is worth adding to bitcoin.

  ## TODO

  - [ ] docs?
  - [x] Integrate systemtap-std-dev/libsystemtap into build (provides the <sys/sdt.h> header)
  - [x] ~dtrace macos support? (is this still a thing?)~ going to focus on linux for now

Pull request description:

  Adds `contrib/signet/miner` for mining signet blocks.

  Adds `bitcoin-util` cli utility, with the idea being it can provide bitcoin related functionality that does not rely on the ability to access a running node. Only subcommand currently is "grind" which takes a hex-encoded header and grinds its nonce until its nBits is satisfied.

  Updates `getblocktemplate` to include `signet_challenge` field, and makes `getblocktemplate` require the signet rule when invoked on the signet change. Removes connectivity and IBD checks from `getblocktemplate` when applied to a test chain (regtest, testnet, signet).

634f6ec4eb contrib: Parse ELF directly for symbol and security checks (Wladimir J. van der Laan)

Pull request description:

  Instead of the ever-messier text parsing of the output of the readelf tool (which is clearly meant for human consumption not to be machine parseable), parse the ELF binaries directly.

  Add a small dependency-less ELF parser specific to the checks.

  This is slightly more secure, too, because it removes potential ambiguity due to misparsing and changes in the output format of `elfread`. It also allows for stricter and more specific ELF format checks in the future.

  This removes the build-time dependency for `readelf`.

  It passes the test-security-check for me locally, ~~though I haven't checked on all platforms~~. I've checked that this works on the cross-compile output for all ELF platforms supported by Bitcoin Core at the moment, as well as PPC64 LE and BE.
