Merge #18575: bench: Remove requirement that all benches use same testing setup
fa1fdb02fc bench: Replace ::mempool globabl with test_setup.mempool (MarcoFalke)
fab1170964 bench: Remove requirement that all benches use RegTestingSetup (MarcoFalke)

Pull request description:

  The benches have always set up one global testing setup. This makes it hard to pick no testing setup at all or one with different params.

  Fix this by removing any global state setup from the main `bench.cpp` and leave the setup to each individual bench.

  One reason to have one global testing setup is to set the datadir location to a tempdir to avoid reading or writing in the default datadir location. But #13687 should prevent this already.

Merge #18702: build: fix ASLR for bitcoin-cli on Windows
315a4d36f7 build: fix ASLR for bitcoin-cli on Windows (fanquake)

Pull request description:

  ASLR is not currently working for the `bitcoin-cli.exe` binary. This is
  due to it not having a .reloc section, which is stripped by default by
  the mingw-w64 ld we use for gitian builds. A good summary of issues with
  ld and mingw-w64 is available in this thread:
  https://sourceware.org/bugzilla/show_bug.cgi?id=19011.

  All other Windows binaries that we distribute (bitcoind, bitcoin-qt,
  bitcoin-wallet, bitcoin-tx and test_bitcoin) do not suffer this issue,
  and currently having working ASLR. This is due to them exporting
  (inadvertent or not) libsecp256k1 symbols, and, as a result, the .reloc
  section is not stripped by ld.

  This change is a temporary workaround, also the same one described here:
  https://www.kb.cert.org/vuls/id/307144/, that causes main() to be
  exported. Exporting a symbol will mean that the .reloc section is not
  stripped, and ASLR will function correctly.

  Ultimately, this will be fixed by using a newer version of binutils (that has this [change](https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=dc9bd8c92af67947db44b3cb428c050259b15cd0)). Whether that's through bumping our gitian distro, or Guix.

  Related to #18629, which has a bunch of additional information in the PR description. If you would like to verify whether or not ASLR is indeed working, with or without this change. One easy way to check is using a tool like [VMMap](https://docs.microsoft.com/en-us/sysinternals/downloads/vmmap).

  Here are the memory mappings for the 0.20.0rc1 `bitcoind.exe` and `bitcoin-cli.exe` binaries. You'll notice that over machine restarts, even though the image is marked `(ASLR)` (which I assume may be due to the header bit being set), no ASLR is actually occuring for `bitcoin-cli.exe`:

Merge #18553: Avoid non-trivial global constants in SHA-NI code
8508473094 Avoid non-trivial global constants in SHA-NI code (Pieter Wuille)

Pull request description:

  This is a potential solution for #18456.

  It seems that the compiler cannot turn `_mm_set_epi64x(<constant>,<constnant>)` into a constant itself, and thus emits a global initializer for the `MASK`, `INIT0`, and `INIT1` global constants in the sha-ni SHA256 implementation.

  Change this by turning them into dumb byte arrays, loading them into an SSE variable whenever needed.

  Tested on a SHA-NI capable machine. I do not observe any obvious performance impact (but this is hard to measure, it's already very fast...).

Merge #18612: script: Remove undocumented and unused operator+
ccccd51908 script: Remove undocumented and unused operator+ (MarcoFalke)

Pull request description:

  This operator has no documented use case and is also unused outside of test code. The test code and all other (imaginary) code that might use this operator is written more clear and concise by the existing CScript push operators for opcodes and data.

  Removing the operator is also going to protect against accidentally reintroducing bugs like this 6ff5f718b6 (diff-8458adcedc17d046942185cb709ff5c3L1135) (last time it was used).

8334ee31f8 scripts: add MACHO LAZY_BINDINGS test to test-security-check.py (fanquake)
7b99c7454c scripts: add MACHO Canary check to security-check.py (fanquake)

Pull request description:

  7b99c7454c uses `otool -Iv` to check for `___stack_chk_fail` in the macOS binaries. Similar to the [ELF check](https://github.com/bitcoin/bitcoin/blob/master/contrib/devtools/security-check.py#L105). Note that looking for a triple underscore prefixed function (as opposed to two for ELF) is correct for the macOS binaries. i.e:
  ```bash
  otool -Iv bitcoind | grep chk
  0x00000001006715b8   509 ___memcpy_chk
  0x00000001006715be   510 ___snprintf_chk
  0x00000001006715c4   511 ___sprintf_chk
  0x00000001006715ca   512 ___stack_chk_fail
  0x00000001006715d6   517 ___vsnprintf_chk
  0x0000000100787898   513 ___stack_chk_guard
  ```

  8334ee31f8 is a follow up to #18295 and adds test cases to `test-security-check.py` that for some reason I didn't add at the time. I'll sort out #18434 so that we can run these tests in the CI.

b155fcda51 doc: fix typo in configure.ac (fanquake)
20a30922fb doc: note why we can't use thread_local with glibc back compat (fanquake)

Pull request description:

  Given that we went through a [gitian build](https://github.com/bitcoin/bitcoin/pull/18681) to remember why this is the case, we might as well make a note of it in configure.ac.

  [From #18681](https://github.com/bitcoin/bitcoin/pull/18681#issuecomment-615526634):

  Looking at the Linux build log, this has failed with:
  ```bash
  Checking glibc back compat...
  bitcoind: symbol __cxa_thread_atexit_impl from unsupported version GLIBC_2.18

  ```

  `__cxa_thread_atexit_impl` is used for [thread_local variable destruction](https://sourceware.org/glibc/wiki/Destructor%20support%20for%20thread_local%20variables):

  > To implement this support, glibc defines __cxa_thread_atexit_impl exclusively for use by libstdc++ (which has the __cxa_thread_atexit to wrap around it), that registers destructors for thread_local variables in a list. Upon thread or process exit, the destructors are called in reverse order in which they were added.

  As suggested, this only became available in glibc 2.18. From the [2.18 release notes](https://sourceware.org/legacy-ml/libc-alpha/2013-08/msg00160.html):

  > * Add support for calling C++11 thread_local object destructors on thread
    and program exit.  This needs compiler support for offloading C++11
    destructor calls to glibc.

  (2) Edits comments that incorrectly describe the test, namely that the `v` variable corresponds to using P2WSH versus P2WPKH, not witness versions.

Merge #18672: test: add further BIP37 size limit checks to p2p_filter.py
c743718558 test: add further BIP37 size limit checks to p2p_filter.py (Sebastian Falbesoner)

Pull request description:

  This is a follow-up PR to #18628. In addition to the hash-functions limit test introduced with commit fa4c29bc1d, it adds checks for the following size limits as defined in [BIP37](https://github.com/bitcoin/bips/blob/master/bip-0037.mediawiki):

  ad message type `filterload`:
  > The filter itself is simply a bit field of arbitrary byte-aligned size. The maximum size is **36,000 bytes**.

  ad message type `filteradd`:
  > The data field must be smaller than or equal to **520 bytes** in size (the maximum size of any potentially matched object).

  Also introduces new constants for the limits (or reuses the max script size constant in case for the `filteradd` limit).

  Also fixes #18711 by changing the misbehaviour check on "filteradd without filterset" (introduced with #18544) below to also use the more commonly used `assert_debug_log` method.

Pull request description:

  The non-`pkg-config` path is ignored as there is a hope to get rid of all of them in #18307.

  As xenial has [libevent 2.0.21](https://packages.ubuntu.com/xenial-updates/libevent-2.0-5) only, the default bionic Docker image is used in the _"[no depends, only system libs, sanitizers: thread (TSan), no wallet]"_ CI test.

Merge #17579: [refactor] Merge getreceivedby tally into GetReceived function
a1d5b12ec0 Merge getreceivedby tally into GetReceived function (Andrew Toth)

Pull request description:

  This PR merges the tally code of `getreceivedbyaddress` and `getreceivedbylabel` into a single function `GetReceived`. This reduces repeated code and makes it similar to `listreceivedbyaddress` and `listreceivedbylabel`, which use the function `ListReceived`. It will also make the change in #14707 simpler and easier to review.

Merge #17831: rpc: doc: Fix and extend getblockstats examples
709998467e rpc: doc: Fix and extend getblockstats examples (Adam Soltys)

Pull request description:

  This pull fixes the example curl command for `getblockstats` which doesn't work as is because it's missing a comma between the params and has single quotes around the second parameter.

  It also adds an additional example of getting block stats by hash by using a known workaround (#15412) to get bitcoin-cli to treat the hash parameter as JSON instead of a string since there is ongoing deliberation about how or whether to fix the root issue (#15448).

Merge #18544: net: limit BIP37 filter lifespan (active between 'filterload'..'filterclear')
a9ecbdfcaa test: add more inactive filter tests to p2p_filter.py (Sebastian Falbesoner)
5eae034996 net: limit BIP37 filter lifespan (active between 'filterload' and 'filterclear') (Sebastian Falbesoner)

Pull request description:

  This PR fixes https://github.com/bitcoin/bitcoin/issues/18483. On the master branch, there is currently _always_ a BIP37 filter set for every peer: if not a specific filter is set through a `filterload` message, a default match-everything filter is instanciated and pointed to via the `CBloomFilter` default constructor; that happens both initially, when the containing structure `TxRelay` is constructed:

  c0b389b335/src/net.h (L812)

  and after a loaded filter is removed again through a `filterclear` message:

  c0b389b335/src/net_processing.cpp (L3201)

  The behaviour was introduced by commit 37c6389c5a (an intentional covert fix for [CVE-2013-5700](https://github.com/bitcoin/bitcoin/pull/18515), according to gmaxwell).

  This default match-everything filter leads to some unintended side-effects:
  1. `getdata` request for filtered blocks (i.e. type `MSG_FILTERED_BLOCK`) are always responded to with `merkleblock`s, even if no filter was set by the peer, see issue #18483 (strictly speaking, this is a violation of BIP37) c0b389b335/src/net_processing.cpp (L1504-L1507)
  2. if a peer sends a `filteradd` message without having loaded a filter via `filterload` before, the intended increasing of the banscore never happens (triggered if `bad` is set to true, a few lines below) c0b389b335/src/net_processing.cpp (L3182-L3186)

  This PR basically activates the `else`-branch code paths for all checks of `pfilter` again (on the master branch, they are dead code) by limiting the pointer's lifespan: instead of always having a filter set, the `pfilter` is only pointing to a `CBloomFilter`-instance after receiving a `filterload` message and the instance is destroyed again (and the pointer nullified) after receiving a `filterclear` message.

  Here is a before/after comparison in behaviour:
  | code part / scenario                          |    master branch                   |   PR branch                                          |
  | --------------------------------------------- | ---------------------------------- | ---------------------------------------------------- |
  | `getdata` processing for `MSG_FILTERED_BLOCK` | always responds with `merkleblock` | only responds if filter was set via `filterload`     |
  | `filteradd` processing, no filter was loaded  | nothing                            | peer's banscore increases by 100 (i.e. disconnect)   |

  On the other code parts where `pfilter` is checked there is no change in the logic behaviour (except that `CBloomFilter::IsRelevantAndUpdate()` is unnecessarily called and immediately returned in the master branch).
  Note that the default constructor of `CBloomFilter` is only used for deserializing the received `filterload` message and nowhere else. The PR also contains a functional test checking that sending `getdata` for filtered blocks is ignored by the node if no bloom filter is set.

Merge #18610: scripted-diff: test: replace command with msgtype (naming)
9df32e820d scripted-diff: test: replace command with msgtype (Sebastian Falbesoner)

Pull request description:

  This is a follow-up PR to https://github.com/bitcoin/bitcoin/pull/18533, which changed the naming of `strCommand` to `msg_type` in the network processing code. The same approach is done here for the function test framework, to get rid of the wrong "command" terminology for network mesage types. (Commands are usually used in the CLI or RPC context, so using the same name in the network message context would only be confusing.)

  The commit was created through the following steps:
  1. search for all occurences of the string "command" within the folder `test/functional`
  ```git grep -i command test/functional > command_finds```
  2. manually sort out all false-positives, i.e. occurences of "command" which describe commands in the correct sense (mostly CLI or RPC related, also some with Socks5)
  3. put the remaining occurences into a scripted-diff (a quite simple one, actually) that renames "command" to "msgtype" in the concerned files.

  The name `msgtype` was intentionally chosen without the underscore `_` as classes beginning with `msg_` define concrete types of messages.

Pull request description:

  `-upgradewallet` is largely incompatible with many recent wallet features and versions. For example, it was disabled if multiple wallets were used and would not work with encrypted wallets that were being upgraded to HD.

  This PR does away with the old method of upgrading upon startup and instead allows users to upgrade their wallets via an `upgradewallet` RPC. This does largely the same thing as the old `-upgradewallet` option but because the wallet is loaded, it can be unlocked to upgrade to HD. Furthermore it is compatible with multiwallet as it works on the individual wallet that is specified by the RPC.

Pull request description:

  actually (?) fix #18561

  See most recent traceback https://travis-ci.org/github/bitcoin/bitcoin/jobs/674668692#L7062

  I believe the reason the error is still there is that ConnectionResetError is derived from OSError:

  ConnectionResetError(ConnectionError(OSError))

  And IOError is an alias for OSError since python 3.3, see https://docs.python.org/3/library/exceptions.html#IOError

  So fix that by renaming IOError to the alias OSError and move the less specific catch clause down a few lines.
