e8e7392311 [addrman] Don't call Clear() if parsing peers.dat fails (John Newbery)
181a1207ba [addrman] Move peers.dat parsing to init.cpp (John Newbery)
Pull request description:
`CAddrMan::Clear()` exists to reset the internal state of `CAddrMan`. It's currently used in two places:
- on startup, if deserializing peers.dat fails, `Clear()` is called to reset to an empty addrman
- in tests, `Clear()` is called to reset the addrman for more tests
In both cases, we can simply destruct the `CAddrMan` and construct a new, empty addrman. That approach is safer - it's possible that `Clear()` could 'reset' the addrman to a state that's not equivalent to a freshly constructed addrman (one actual example of this is that `Clear()` does not clear the `m_tried_collisions` set). On the other hand, if we destruct and then construct a fresh addrman, we're guaranteed that the new object is empty.
This wasn't possible when addrman was initially implemented, since it was a global, and so it would only be destructed on shutdown. However, addrman is now owned by `node.context`, so we have control over its destruction/construction.

Clear() is now only called from the ctor, so just inline the code into
that function.
The LOCK(cs) can be removed, since there can be no data races in the ctor.
Also move the function definition out of the header and into the cpp file.
Just use unique_ptr<CAddrMan>s and reset the pointer if a frest addrman is required.
Also make CAddrMan::Clear() private to ensure that no call sites are missed.
cd37356ff9 [crypto] Fix K1/K2 use in ChaCha20-Poly1305 AEAD (Dhruv Mehta)
Pull request description:
BIP324 mentions K1 is used for the associated data and K2 is used for the payload. The code does the opposite. This is not a security problem but will be a problem across implementations based on the HKDF key derivations.
BIP324 author Jonas Schnelli thinks a [code update will be better](https://github.com/bitcoin/bitcoin/pull/15649#discussion_r440780669) than a BIP update.
If this PR is merged:

`bool CAddrDB::Read(CAddrMan& addr, CDataStream& ssPeers)` is _only_
called from the tests, and the call to addr.Clear() only exists so that
a test that Clear() is called passes. Remove that test and the call.
Now that we manage the lifespan of node.addrman, we can just reset
node.addrman to a newly initialized CAddrMan if parsing peers.dat
fails, eliminating the possibility that Clear() leaves some old state
behind.

5c5d0b6264 Add FoundBlock.found member (Russell Yanofsky)
Pull request description:
This change lets IPC serialization code handle FoundBlock arguments more simply and efficiently. Without this change there was no way to determine from a FoundBlock object whether a block was found or not. So in order to correctly implement behavior of leaving FoundBlock output variables unmodified when a block was not found, IPC code would have to read preexisting output variable values from the local process, send them to the remote process, receive output values back from the remote process, and save them to output variables unconditionally. With FoundBlock.found method, the process is simpler. There's no need to read or send preexisting local output variable values, just to read final output values from the remote process and set them conditionally if the block was found.

Rather than defining more strings, reuse PACKAGE_VERSION, which is

We already use PACKAGE_VERSION for `ProductVersion` and `FileVersion` in setup.nsi.
Use interfaces::Init::make* methods instead of interfaces::Make*
functions, so interfaces can be constructed differently in different
executables without having to change any code. (So for example
bitcoin-gui can make an interfaces::Node pointer that communicates with
a bitcoin-node subprocess, while bitcoin-qt can make an interfaces::Node
pointer that starts node code in the same process.)
60e0cbdd57 [addrman] Merge the two Add() functions (Amiti Uttarwar)
Pull request description:
This PR merges the two definitions of this overloaded function to reduce code duplication.
When these functions were introduced in 5fee401fe1, there were multiple places that invoked `Add()` with a single addr and a vector of addrs each, so it made sense to overload the function. I could see how the small difference in log statement was more meaningful when a peer was added via IRC :)
Now, the definition of `Add()` that takes in a single address is only invoked from the hidden/test-only RPC `addpeeraddress`. These changes should not cause any observable difference, and are covered by the existing tests that use this RPC endpoint.

2de222c401 wallet: Use GetSelectionAmount for target value calculations (Andrew Chow)
Pull request description:
The `m_value` used for the target calculation in `ApproximateBestSubset` is incorrect, it should be `GetSelectionAmount`. This causes a bug that is only apparent when the minimum relay fee is set to be very high.
A test case is added for this, in addition to an assert in `CreateTransactionInternal` that would have also caught this issue if someone were able to hit the edge case.

5fe8100ff3 Change the wallet_backup.py test to use the restorewallet RPC command instead of restoring wallets manually. (lsilva01)
ae23faba6f Add a new RPC command: restorewallet (lsilva01)
Pull request description:
As far as I know, there is no command to restore the wallet from a backup file.
The only way to do this is to replace the `wallet.dat` of a newly created wallet with the backup file, which is hardly an intuitive way.
This PR implements the `restorewallet` RPC command which restores the wallet from the backup file.
To test:
First create a backup file:
`$ bitcoin-cli -rpcwallet="wallet-01" backupwallet /home/Backups/wallet-01.bak`
Then restore it in another wallet:
`$ bitcoin-cli restorewallet "restored-wallet-01" /home/Backups/wallet-01.bak`

4844b74ba7 p2p: log addrman consistency checks (Jon Atack)
Pull request description:
This mini-patch picks up #22479 to log addrman consistency checks in the `BCLOG::ADDRMAN` category when they are enabled with the `-checkaddrman=<n>` configuration option for values of n greater than 0.
```
$ ./src/bitcoind -signet -checkaddrman=20 -debug=addrman
...
2021-08-13T11:14:45Z Addrman checks started: new 3352, tried 89, total 3441
2021-08-13T11:14:45Z Addrman checks completed successfully
```
This allows people to
- verify the checks are running
- see when and how often they are being performed
- see the number of new/tried/total addrman entries per check
- see the start/end of the checks
Thanks to John Newbery for ideas to improve this logging.
