Merge #20248: test: fix length of R check in key_signature_tests
89895773b72275a620951730aef0b52e9437bc13 Fix length of R check in test/key_tests.cpp:key_signature_tests (Dmitry Petukhov)

Pull request description:

  The code before the fix only checked the length of R value of the last
  signature in the loop, and only for equality (but the length can be
  less than 32)

  The fixed code checks that length of the R value is less than or equal
  to 32 on each iteration of the loop

Merge #20560: fuzz: Link all targets once

44444ba759480237172d83f42374c5c29c76eda0 fuzz: Link all targets once (MarcoFalke)

Pull request description:

  Currently the linker is invoked more than 150 times when compiling with `--enable-fuzz`. This is problematic for several reasons:

  * It wastes disk space north of 20 GB, as all libraries and sanitizers are linked more than 150 times
  * It wastes CPU time, as the link step can practically not be cached (similar to ccache for object files)
  * It makes it a blocker to compile the fuzz tests by default for non-fuzz builds #19388, for the aforementioned reasons
  * The build file is several thousand lines of code, without doing anything meaningful except listing each fuzz target in a highly verbose manner
  * It makes writing new fuzz tests unnecessarily hard, as build system knowledge is required; Compare that to boost unit tests, which can be added by simply editing an existing cpp file
  * It encourages fuzz tests that re-use the `buffer` or assume the `buffer` to be concatenations of seeds, which increases complexity of seeds and complexity for the fuzz engine to explore; Thus reducing the effectiveness of the affected fuzz targets

  Fixes #20088

8c09c0c1d18885ef94f79b3f2d073f43269bc95d fuzz: Avoid time-based "non-determinism" in fuzzing harnesses by using mocked GetTime() (practicalswift)

Pull request description:

  Avoid time-based "non-determinism" in fuzzing harnesses by using mocked `GetTime()`.

  Prior to this commit the fuzzing harnesses `banman`, `connman`, `net` and `rbf` had time-based "non-determinism". `addrman` is fixed in #20425. `process_message` and `process_messages` are left to fix: simply using mock time is not enough for them due to interaction with `IsInitialBlockDownload()`.

  See [`doc/fuzzing.md`](https://github.com/bitcoin/bitcoin/blob/master/doc/fuzzing.md) for information on how to fuzz Bitcoin Core. Don't forget to contribute any coverage increasing inputs you find to the [Bitcoin Core fuzzing corpus repo](https://github.com/bitcoin-core/qa-assets).

91d61952a82af3e8887e8ae532ecc19d87fe9073 Simplify and clarify extra outbound peer counting (Suhas Daftuar)

Pull request description:

  To make eclipse attacks more difficult, regularly initiate outbound connections
  and stay connected long enough to sync headers and potentially learn of new
  blocks. If we learn a new block, rotate out an existing block-relay peer in
  favor of the new peer.

  This augments the existing outbound peer rotation that exists -- currently we
  make new full-relay connections when our tip is stale, which we disconnect
  after waiting a small time to see if we learn a new block.  As block-relay
  connections use minimal bandwidth, we can make these connections regularly and
  not just when our tip is stale.

  Like feeler connections, these connections are not aggressive; whenever our
  timer fires (once every 5 minutes on average), we'll try to initiate a new
  block-relay connection as described, but if we fail to connect we just wait for
  our timer to fire again before repeating with a new peer.

I did not verify the behavior of `m_start_extra_block_relay_peers` only being enabled after initial chain sync. Since my last review, one unneeded `cs_main` lock was removed.

81137c60fe test: Add new ChainTestingSetup and use it
Previously, the validation_chainstatemanager_tests test suite
instantiated its own duplicate ChainstateManager on which tests were
performed.

This wasn't a problem for the specific actions performed in
that suite. However, the existence of this duplicate ChainstateManager
and the fact that many of our validation static functions reach for
g_chainman, ::Chain(state|)Active means we may end up acting on two
different CChainStates should we write more extensive tests in the
future.

This change adds a new ChainTestingSetup which performs all
initialization previously done by TestingSetup except:

1. RPC command registration
2. ChainState initialization
3. Genesis Activation
4. {Ban,Conn,Peer}Man initialization

Means that we will no longer need to initialize a duplicate
ChainstateManger in order to test the initialization codepaths of
CChainState and ChainstateManager.

Lastly, this change has the additional benefit of allowing for
review-only assertions meant to show correctness to work in future work
de-globalizing g_chainman.

In the test chainstatemanager_rebalance_caches, an additional
LoadGenesisBlock call is added as MaybeReblanaceCaches eventually calls
FlushBlockFile, which tries to access vinfoBlockFile[nLastBlockFile],
which is out of bounds when LoadGenesisBlock hasn't been called yet.

-----

Note for the future:

The class con/destructor inheritance structure we have for these
TestingSetup classes is probably not the most suitable abstraction. In
particular, for both TestingSetup and ChainTestingSetup, we need to stop
the scheduler first before anything else. Otherwise classes depending on
the scheduler may be referenced by the scheduler after said classes are
freed. This means that there's no clear parallel between our teardown
code and C++'s destructuring order for class hierarchies.

Future work should strive to coalesce (as much as possible) test and
non-test init codepaths and perhaps structure it in a more fail-proof
way.

3fbbb9a640 refactor: Get rid of more redundant chain methods
This just drops three interfaces::Chain methods replacing them with other calls.

Motivation for removing these chain methods:

- Need to get rid of findFirstBlockWithTimeAndHeight for #10102, which doesn't
  support overloaded methods
- Followup from
  https://github.com/bitcoin/bitcoin/pull/16426#discussion_r412487403
- phantomcircuit comments about findNextBlock test
  http://www.erisian.com.au/bitcoin-core-dev/log-2020-06-06.html#l-214

Behavior is not changing in any way here. A TODO comment in
ScanForWalletTransactions was removed, but just because it was invalid (see
https://github.com/bitcoin/bitcoin/pull/19195#discussion_r448020762), not
because it was implemented.

03bfeee957ab7e3b6aece82b9561774648094f54 interface: remove unused estimateSmartFee method from node (Antoine Poinsot)

Pull request description:

  If the `blocksonly` mode is turned on after running with transaction
  relay enabled for a while, the fee estimation will serve outdated data
  to both the internal wallet and to external applications that might be
  feerate-sensitive and make use of `estimatesmartfee` (for example a
  Lightning Network node).

  This has already caused issues (for example https://github.com/bitcoin/bitcoin/issues/16840 (C-lightning), or https://github.com/lightningnetwork/lnd/issues/2562 (LND)) and it seems prudent to fail rather than to give inaccurate values.

  This fixes #16840, and closes #16890 which tried to fix the symptoms (RPC) but not the cause as mentioned by sdaftuar :
  > If this is a substantial problem, then I would think we should take action to protect our own wallet users as well (rather than hide the results of what our fee estimation would do!).

Pull request description:

  I found the `extended-lint-cppcheck` linter still uses `std=c++11` when reviewing #20471. The only difference in the output after this change is one line is missing:

  ```
  src/script/descriptor.cpp:159:5: warning: Struct 'PubkeyProvider' has a constructor with 1 argument that is not explicit. [noExplicitConstructor]
  ```

  After some digging, I am still not sure why this one is ignored with c++17 when 40 other`noExplicitConstructor` warnings were still appearing.

  In the second commit, I fix these warnings, adding `explicit` where appropriate and adding fixes to ignore otherwise.

9d4b4b2c2c49774523de740d6492ee5b1ee15e74 refactor: Avoid double to int cast for nCheckFrequency (Elle Mouton)

Pull request description:

  This PR cleans up the CTxMemPool interface by including the ratio used to determine when a mempool sanity check should run in the constructor of CTxMempool instead of using nCheckFrequency which required a cast from a double to a uint32_t. Since nCheckFrequency (now called m_check_ratio) is set in the constructor and only every read from there after, it can be turned into a const and no longer needs to be guarded by the 'cs' lock.

  Since nCheckFrequency/m_check_ratio no longer needs to lock the 'cs' mutux, mutex lock line in the "CTxMempool::check" function can be moved below where the m_check_ratio variable is checked. Since the variable is 0 by default (meaning that "CTxMempool::check" will most likely not run its logic) this saves us from unnecessarily grabbing the lock.

Fix length of R check in test/key_tests.cpp:key_signature_tests
The code before the fix only checked the length of R value of the last
signature in the loop, and only for equality (but the length can be
less than 32)

The fixed code checks that length of the R value is less than or equal
to 32 on each iteration of the loop

The BOOST_CHECK(sig.size() <= 70) is merged with sig[3] <= 32 check,
and BOOST_CHECKs are moved outside the loop, for efficiency

Pull request description:

  Using `uint8_t` from the beginning when messages are `recv`ed has two style benefits:
  * The signedness is clear from reading the code, as it does not depend on the architecture
  * When passing the bytes on, the need for static signedness casts is dropped, making the code a bit less verbose and more coherent

Merge #20223: build: Drop the leading 0 from the version number
8f7b93047581c67f2133cdb8c7845471de66c30f Drop the leading 0 from the version number (Andrew Chow)

Pull request description:

  Removes the leading 0 from the version number. The minor version, which we had been using as the major version, is now the major version. The revision, which we had been using as the minor version, is now the minor version. The revision number is dropped. The build number is promoted to being part of the version number. This also avoids issues where it was accidentally not included in the version number.

  The CLIENT_VERSION remains the same format as previous as previously, as the Major version was 0 so it never actually got included in it.

  The user agent string formatter is updated to follow this new versioning.

  ***

  Honestly I'm just tired of all of the people asking for "1.0" that maybe this'll shut them up. Skip the whole 1.0 thing and go straight to version 22.0!

  Also, this means that the terminology we commonly use lines up with how the variables are named. So major versions are actually bumping the major version number, etc.

ecc6cf1a3b097b9b5b047282063a0b6779631b83 test: fix creation of std::string objects with \0s (Vasil Dimov)

Pull request description:

  A string literal `"abc"` contains a terminating `\0`, so that is 4
  bytes. There is no need to write `"abc\0"` unless two terminating
  `\0`s are necessary.

  `std::string` objects do not internally contain a terminating `\0`, so
  `std::string("abc")` creates a string with size 3 and is the same as
  `std::string("abc", 3)`.

  In `"\01"` the `01` part is interpreted as one number (1) and that is
  the same as `"\1"` which is a string like `{1, 0}` whereas `"\0z"` is a
  string like `{0, 'z', 0}`. To create a string like `{0, '1', 0}` one
  must use `"\0" "1"`.

  Adjust the tests accordingly.

Pull request description:

  This PR builds on #11413 and #20220 to address #19543.

  - replace overloading the conf_target and estimate_mode params with `fee_rate` in sat/vB in the sendtoaddress, sendmany, send, fundrawtransaction, walletcreatefundedpsbt, and bumpfee RPCs

  - allow non-actionable conf_target value of `0` and estimate_mode value of `""` to be passed to use `fee_rate` as a positional argument, in addition to as a named argument

  - fix a bug in the experimental send RPC described in https://github.com/bitcoin/bitcoin/pull/20220#discussion_r513789526 where args were not being passed correctly into the options values

  - update the feerate error message units for these RPCs from BTC/kB to sat/vB

  - update the test coverage, help docs, doxygen docs, and some of the RPC examples

  - other changes to address the excellent review feedback
