Merge #19140: tests: Avoid fuzzer-specific nullptr dereference in libevent when handling PROXY requests
20d31bdd92 tests: Avoid fuzzer-specific nullptr dereference in libevent when handling PROXY requests (practicalswift)

Pull request description:

  Avoid constructing requests that will be interpreted by libevent as PROXY requests to avoid triggering a `nullptr` dereference. Split out from #19074 as suggested by MarcoFalke.

  The dereference (`req->evcon->http_server`) takes place in `evhttp_parse_request_line` and is a consequence of our hacky but necessary use of the internal function `evhttp_parse_firstline_` in the `http_request` fuzzing harness.

  The suggested workaround is not aesthetically pleasing, but it successfully avoids the troublesome code path.

  `" http:// HTTP/1.1\n"` was a crashing input prior to this workaround.

Merge #19219: Replace automatic bans with discouragement filter
2ad58381ff Clean up separated ban/discourage interface (Pieter Wuille)
b691f2df5f Replace automatic bans with discouragement filter (Pieter Wuille)

Pull request description:

  This patch improves performance and resource usage around IP addresses that are banned for misbehavior. They're already not actually banned since #14929, as connections from them are still allowed, but they are preferred for eviction if the inbound connection slots are full.

  Stop treating these like manually banned IP ranges, and instead just keep them in a rolling Bloom filter of misbehaving nodes, which isn't persisted to disk or exposed through the ban framework. The effect remains the same: preferred for eviction, avoided for outgoing connections, and not relayed to other peers.

  Also change the name of this mechanism to "discouraged" to better reflect reality.

Pull request description:

  This is another intermediate part of the Coinstats Index (tracked in #18000).

  Sjors suggested [here](https://github.com/bitcoin/bitcoin/pull/18000#issuecomment-641423019) that the part of the changes in #19145 that don't rely on the new `hash_type` muhash, i.e. that are for `hash_type=none`, could be merged separately from everything involving muhash. So these changes are extracted from #19145 here and can be merged without any other requirements.

  Building the index with no UTXO set hash is still valuable because `gettxoutsetinfo` can still be used to audit the `total_amount` for example. By itself this PR is not a huge improvement, `hash_type=none` is speeding up `gettxoutsetinfo` by about 10%, but it enables the implementation of an index on top of it in a follow-up and that means large parts of the index code of Coinstats Index can be merged while reviews for the hashing algorithm might take longer.

72f6bec1da rpc: show both UTXOs in decodepsbt (Andrew Chow)

Pull request description:

  Due to recent changes to hardware wallets, the full previous transaction will need to be provided for segwit inputs. Since some software may be checking for the existence of a `witness_utxo` to determine whether to produce a segwit signature, we keep that field to ease the transition.

  Because all of the sanity checks implemented by the `IsSane` functions were related to having mixed segwit and non-segwit data in a PSBT, those functions are removed as those checks are no longer proper.

  Some tests are updated/removed to accommodate this and a simple test added to check that both UTXOs are being added to segwit inputs.

  As discussed in the wallet IRC meeting, our own signer will not require `non_witness_utxo` for segwit inputs.

Merge #19366: tests: Provide main(...) function in fuzzer. Allow building uninstrumented harnesses with --enable-fuzz.
1087807b2b tests: Provide main(...) function in fuzzer (practicalswift)

Pull request description:

  Provide `main(...)` function in fuzzer. Allow building uninstrumented harnesses with only `--enable-fuzz`.

  This PR restores the behaviour to how things worked prior to #18008. #18008 worked around an macOS specific issue but did it in a way which unnecessarily affected platforms not in need of the workaround :)

  Before this patch:

  ```
  # Build uninstrumented fuzzing harness (no libFuzzer/AFL/other-fuzzer-instrumentation)
  $ ./configure --enable-fuzz
  $ make
    CXXLD    test/fuzz/span
  /usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/Scrt1.o: In function `_start':
  (.text+0x20): undefined reference to `main'
  collect2: error: ld returned 1 exit status
  Makefile:7244: recipe for target 'test/fuzz/span' failed
  make[2]: *** [test/fuzz/span] Error 1
  make[2]: *** Waiting for unfinished jobs....
  $
  ```

  After this patch:

  ```
  # Build uninstrumented fuzzing harness (no libFuzzer/AFL/other-fuzzer-instrumentation)
  $ ./configure --enable-fuzz
  $ make
  $ echo foo | src/test/fuzz/span
  $
  ```

  The examples above show the change in non-macOS functionality. macOS functionality is unaffected by this patch.

Pull request description:

  This improves our Span class by making it closer to the C++20 `std::span` one:
  * ~~Support conversion between compatible Spans (e.g. `Span<char>` to `Span<const char>`).~~ (done in #18591)
  * Make the size type `std::size_t` rather than `std::ptrdiff_t` (the C++20 one underwent the same change).
  * Support construction of Spans directly from arrays, `std::string`s, `std::array`s, `std::vector`s, `prevector`s, ... (for all but arrays, this only works for const containers to prevent surprises).

  And then make use of those improvements in various call sites.

  I realize the template magic used looks scary, but it's only needed to make overload resultion make the right choices. Note that the operations done on values are all extremely simple: no casts, explicit conversions, or warning-silencing constructions. That should hopefully make it simpler to review.

77b79fa6ef refactor: Error message bilingual_str consistency
- Move the decision whether to translate an error message to where it is
  defined. This simplifies call sites: no more `InitError(Untranslated(...))`.

- Make all functions in `util/error.h` consistently return a
  `bilingual_str`. We've decided to use this as error message type so
  let's roll with it.

This has no functional changes: no messages are changed, no new
translation messages are defined.

Merge #19053: refactor: replace CNode pointers by references within net_processing.{h,cpp}
8b3136bd30 refactor: replace CNode pointers by references within net_processing.{h,cpp} (Sebastian Falbesoner)

Pull request description:

  This PR is inspired by a [recent code review comment](https://github.com/bitcoin/bitcoin/pull/19010#discussion_r426954791) on a PR that introduced new functions to the net_processing module. The point of the discussion was basically that whenever we pass something not by value (in the concrete example it was about `CNode*` and `CConnman*`) we should either use
  * a pointer (```CType*```) with null pointer check or
  * a reference (```CType&```)

  To keep things simple, this PR for a first approach
  * only tackles `CNode*` pointers
  * only within the net_processing module, i.e. no changes that would need adaption in other modules
  * keeps the names of the variables as they are

  I'm aware that PRs like this are kind of a PITA to review, but I think the code quality would increase if we get rid of pointers without nullptr check -- bloating up the code by adding all the missing checks would be the worse alternative, in my opinion.

  Possible follow-up PRs, in case this is received well:
  * replace CNode pointers by references for net module
  * replace CConnman pointers by references for net_processing module
  * ...

  Telling from the line numbers, it looks like `nMisbehavior` wrapped around.

  Fix that by calling `StopNodes` after each exec, which should clear the node state and thus `nMisbehavior`.

Pull request description:

  The global `g_chainman` has recently been introduced in #17737. The chainstate manager is primarily needed for the assumeutxo feature, but it can also simplify testing in the future.

  The goal of this pull is to make the global chainstate manager internal to validation, so that all external code does not depend on globals and that unit or fuzz tests can pass in their (potentially mocked) chainstate manager.

  I suggest reviewing the pull request commit-by-commit. It should be relatively straightforward refactoring that does not change behavior at all.

Pull request description:

  This improves/documents the failure cases inside the asmap interpreter. None of the changes are bug fixes (they only change behavior for corrupted asmap files), but they may make things easier to follow.

  In a second step, a sanity checker is added that effectively executes every potential code path through the asmap file, checking the same failure cases as the interpreter, and more. It takes around 30 ms to run for me for a 1.2 MB asmap file.

  I've verified that this accepts asmap files constructed by https://github.com/sipa/asmap/blob/master/buildmap.py with a large dataset, and no longer accepts it with 1 bit changed in it.

Merge #18806: net: remove is{Empty,Full} flags from CBloomFilter, clarify CVE fix
1ad8ea2b73 net: remove is{Empty,Full} flags from CBloomFilter, clarify CVE fix (Sebastian Falbesoner)

Pull request description:

  The BIP37 bloom filter class `CBloomFilter` contains two flags `isEmpty`/`isFull` together with an update method with the purpose to, according to the comments, "avoid wasting cpu", i.e. the mechanism should serve as an optimization for the trivial cases of empty (all bits zero) or full (all bits one) filters.
  However, the real reason of adding those flags (introduced with commit 37c6389c5a by gmaxwell) was a _covert fix_ of [CVE-2013-5700](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-5700), a vulnerability that allowed a divide-by-zero remote node crash.
  According to gmaxwell himself (https://github.com/bitcoin/bitcoin/pull/9060#issuecomment-257749165):
  > the IsEmpty/IsFull optimizations were largely a pretextual optimization intended to make unexploitable a remote crash vulnerability (integer division by zero) that existed in the original bloom filtering code without disclosing it. I'm doubtful that they are all that useful. :)

  For more information on how to trigger this crash, see PR https://github.com/bitcoin/bitcoin/pull/18515 which contains a detailled description and a regression test. It has also been discussed on a [recent PR club meeting on fuzzing](https://bitcoincore.reviews/18521.html).

  The covert fix code already led to issues and PR based on the wrong assumption that the flags are there for optimization reasons (see #16886 and #16922). This PR gets rid of the flags and the update method and just focuses on the CVE fix itself, i.e. it can be seen as a revert of the covert fix commit modulo the actual fix.

Merge #18682: fuzz: http_request workaround for libevent < 2.1.1
6f8b498d18 fuzz: http_request workaround for libevent < 2.1.1 (Sebastian Falbesoner)

Pull request description:

  The fuzz test `http_request` calls the following two internal libevent functions:
  * `evhttp_parse_firstline_`
  * `evhttp_parse_headers_`

  Before libevent 2.1.1 however, internal functions names didn't end with an underscore (see libevent commit 8ac3c4c25b and [Changelog for 2.1.1.-alpha](https://github.com/libevent/libevent/blob/master/ChangeLog#L1830) when the change was first mentioned) hence the build fails with a linking error.
  This PR adds a preprocessor workaround to the test that checks for the libevent version (via ~`_EVENT_NUMERIC_VERSION`~ `LIBEVENT_VERSION_NUMBER`) and creates wrapper functions mapping to naming scheme without underscore in case the version is older than 2.1.1.

  Tested with Ubuntu Xenial 16.04.6 LTS and clang-8.

Merge #18673: scripted-diff: Sort test includes
fa4632c417 test: Move boost/stdlib includes last (MarcoFalke)
fa488f131f scripted-diff: Bump copyright headers (MarcoFalke)
fac5c37300 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.
