Merge bitcoin/bitcoin#28913: coins: make sure PoolAllocator uses the correct alignment
d5b4c0b69e543de51bb37d602d488ee0949ba185 pool: change memusage_test to use int64_t, add allocation check (Martin Leitner-Ankerl)
ce881bf9fcb7c30bb1fafd6ce38844f4f829452a pool: make sure PoolAllocator uses the correct alignment (Martin Leitner-Ankerl)

Pull request description:

  The class `CTxOut` has a member `CAmount` which is an int64_t, and on ARM 32bit int64_t are 8 byte aligned, which is larger than the pointer alignment of 4 bytes.

  So for `CCoinsMap` to be able to use the pool, we need to use the alignment of the member instead of just `alignof(void*)`.

  This fixes #28906 (first noted in https://github.com/bitcoin/bitcoin/issues/28718#issuecomment-1807197107) and #28440.

non-scripted-diff: bump copyright year to 2023
that's a result of:

it is not scripted diff, because it works differentlly on my localhost and in CI:
CI doesn't want to use git commit date which is mocked to 30th Dec of 2023

Merge #19111: Limit scope of all global std::once_flag
fa9c67559186f5416c1c0b26c0a1d5e72c234ccb Limit scope of all global std::once_flag (MarcoFalke)

Pull request description:

  `once_flag` is  a helper (as the name might suggest) to execute a callable only once. Thus, the scope of the flag does never need to extend beyond where the callable is called. Typically this is function scope.

  Move all the flags to function scope to
  * simplify code review
  * avoid mistakes where similarly named flags are accidentally exchanged
  * avoid polluting the global scope

Merge bitcoin/bitcoin#25320: util: modify Win32LockedPageAllocator to query windows for limit.
1cb42aeda37f4979923cd7e1c85febe994480de6 util: modify Win32LockedPageAllocator to query windows for limit (Oskar Mendel)

Pull request description:

  This PR resolves a todo within the Win32LockedPageAllocator: `// TODO is there a limit on Windows, how to get it?`.
  The idea is to use the Windows API to get the limits like the posix based allocator does with `getrlimit`.

  I use [GetProcessWorkingSetSize](https://docs.microsoft.com/en-us/windows/win32/api/memoryapi/nf-memoryapi-getprocessworkingsetsize) to perform this task and fallback to `return std::numeric_limits<size_t>::max();` just like the posix implementation does.

Merge #15704: Move Win32 defines to configure.ac to ensure they are globally defined
1ccb9f30c040daf688f89f0d63e9f5e7b131d193 Move Win32 defines to configure.ac to ensure they are globally defined (Luke Dashjr)

Pull request description:

  #9245 no longer needs this, since the main `_WIN32_WINNT` got bumped by something else.

  So rather than just lose it, might as well get it merged in independently.

  I'm not aware of any practical effects, but it seems safer to use the same API versions everywhere.

fac5c373006a9e4bcbb56843bb85f1aca4d87599 scripted-diff: Sort test includes (MarcoFalke)

Pull request description:

  When writing tests, often includes need to be added or removed. Currently the list of includes is not sorted, so developers that write tests and have `clang-format` installed will either have an unrelated change (sorting) included in their commit or they will have to manually undo the sort.

  This pull preempts both issues by just sorting all includes in one commit.

  Please be aware that this is **NOT** a change to policy to enforce clang-format or any other developer guideline or process. Developers are free to use whatever tool they want, see also #18651.

  Edit: Also includes a commit to bump the copyright headers, so that the touched files don't need to be touched again for that.

fix: Fix missing includes (#5295)
The `<stdexcept>` include is needed for `std::runtime_error` definition.
The `<cstdint>` include is needed for `uint8_t` and `uint32_t`
definition.

## Issue being fixed or feature implemented
Compilation failure with GCC 13.
GCC 13 is more strict about missing includes that were included
indirectly by previous versions of GCC.


## What was done?
Added missing includes.

## How Has This Been Tested?
Successful compilation on Fedora 38 with GCC 13. All tests passed
successfully.


## Breaking Changes
None.

cac30a436cab3641bba3b774d3d3ddbc426e7908 Clean up logic in memory_cleanse() for MSVC (Tim Ruffing)

Pull request description:

  When working on https://github.com/bitcoin-core/secp256k1/issues/185, I noticed that the logic in memory_cleanse(), which is supposed to clear memory securely, is weird on MSVC. While it's correct, it's at least a code smell because the code clears the memory twice on MSVC. This weirdness was introduced by #11558.

  This PR fixes the logic on MSVC and also improves the docs around this function. Best reviewed in individual commits, see the commit messages for more rationale. The second commit touches only comments.

ca126d490b0ff6960e135f3c77b2b2d4892a5744 Fix out-of-bounds write in case of failing mmap(...) in PosixLockedPageAllocator::AllocateLocked (practicalswift)

Pull request description:

  `mmap(...)` returns `MAP_FAILED` (`(void *) -1`) in case of allocation failure.

  `PosixLockedPageAllocator::AllocateLocked(...)` did not check for allocation failures prior to this PR.

  Instead the invalid memory address `(void *) -1` (`0xffffffffffffffff`) was passed to the caller as if it was a valid address.

  After some operations the address is wrapped around from `0xffffffffffffffff` to `0x00000003ffdf` (`0xffffffffffffffff + 262112 == 0x00000003ffdf`);

  The resulting address `0x00000003ffdf` is then written to.

Pull request description:

  Changes in #12048 cause a compilation error in Arena::walk() when
  ARENA_DEBUG is defined. Specifically, Arena's chunks_free map was
  changed to have a different value type.

  Additionally, missing includes cause other compilation errors when
  ARENA_DEBUG is defined.

  Reproduced with:

  make CPPFLAGS=-DARENA_DEBUG

Merge #12048: Use best-fit strategy in Arena, now O(log(n)) instead O(n)
5fbf7c4 fix nits: variable naming, typos (Martin Ankerl)
1e0ee90 Use best-fit strategy in Arena, now O(log(n)) instead O(n) (Martin Ankerl)

Pull request description:

  This replaces the first-fit algorithm used in the Arena with a best-fit. According to "Dynamic Storage Allocation: A Survey and Critical Review", Wilson et. al. 1995, http://www.scs.stanford.edu/14wi-cs140/sched/readings/wilson.pdf, both startegies work well in practice.

  The advantage of using best-fit is that we can switch the O(n) allocation to O(log(n)). Additionally, some previously O(log(n)) operations are now O(1) operations by using hash maps. The end effect is that the benchmark runs about 2.5 times faster on my machine:

      # Benchmark, evals, iterations, total, min, max, median
      old: BenchLockedPool, 5, 530, 5.25749, 0.00196938, 0.00199755, 0.00198172
      new: BenchLockedPool, 5, 1300, 5.11313, 0.000781493, 0.000793314, 0.00078606

  I've run all unit tests and benchmarks, and increased the number of iterations so that BenchLockedPool takes about 5 seconds again.

Merge #11558: Minimal code changes to allow msvc compilation
fbf327b Minimal code changes to allow msvc compilation. (Aaron Clauson)

Pull request description:

  These changes are required to allow the Bitcoin source to build with Microsoft's C++ compiler (#11562 is also required).

  I looked around for a better place for the typedef of ssize_t which is in random.h. The best candidate looks like src/compat.h but I figured including that header in random.h is a bigger change than the typedef. Note that the same typedef is in at least two other places including the OpenSSL and Berkeley DB headers so some of the Bitcoin code already picks it up.

Pull request description:

  Use `nullptr` instead of zero (0) as the null pointer constant.

  The road towards `nullptr` (C++11) is split into two PRs:
  * `NULL` → `nullptr` is handled in PR #10483 (scripted)
  * `0` → `nullptr` is handled in PR #10645 (manual, this PR)

  By using the C++11 keyword `nullptr` we are guaranteed a prvalue of type `std::nullptr_t`.

Merge #11196: Switch memory_cleanse implementation to BoringSSL's to ensure memory clearing even with -lto
1444c2e Switch memory_cleanse implementation to BoringSSL's to ensure memory clearing even with link-time optimization. (Adam Langley)

Pull request description:

  The implementation we currently use from OpenSSL prevents the compiler from optimizing away clensing operations on blocks of memory that are about to be released, but this protection is not extended to link-time optimization. This commit copies the solution cooked up by Google compiler engineers which uses inline assembly directives to instruct the compiler not to optimize out the call under any circumstances. As the code is in-lined, this has the added advantage of removing one more OpenSSL dependency.

  Regarding license compatibility, Google's contributions to BoringSSL library, including this code, is made available under the ISC license, which is MIT compatible.

Implement mt_pooled_secure_allocator and use it for BLS secure allocation (#2375)
* Add pooled_secure_allocator and mt_pooled_secure_allocator

* Use mt_pooled_secure_allocator for BLS secure allocation

The old solution relied on thread-local-storage and was thus not compatible
to libc6 2.11 (which is the minimum supported version we use).

Also, the old solution turned out to be erroneous. It would have crashed
or memory leaked when ownership of CBLSPrivateKey would be handled over
to another thread.

* Add new header files to Makefile.am

* Fix copyright headers of new files

* Bail out early from secure deallocation

* Clean up global BLS keys when shutting down
