`CConnman::GetAddedNodeInfo` is used both to get a list of addresses to manually connect to
in `CConnman::ThreadOpenAddedConnections`, and to report about manually added connections in
`getaddednodeinfo`. In both cases, all addresses added to `m_added_nodes` are returned, however
the nodes we are already connected to are only relevant to the latter, in the former they are
actively discarded.
Parametrizes `CConnman::GetAddedNodeInfo` so we can ask for only addresses we are not connected to,
to avoid passing useless information around.
fb3e812277 p2p: return `CSubNet` in `LookupSubNet` (brunoerg)
Pull request description:
Analyzing the usage of `LookupSubNet`, noticed that most cases uses check if the subnet is valid by calling `subnet.IsValid()`, and the boolean returned by `LookupSubNet` hasn't been used so much, see:
29d540b7ad/src/httpserver.cpp (L172-L174)29d540b7ad/src/net_permissions.cpp (L114-L116)
It makes sense to return `CSubNet` instead of `bool`.

cdb14d79e8 [net processing] Use HasWitness over comparing (w)txids (dergoegge)
Pull request description:
We currently have two different identifiers for transactions: `txid` (refering to the hash of a transaction without witness data) and `wtxid` (referring to the hash of a transaction including witness data). Both are typed as `uint256` which could lead to type-safety bugs in which one transaction identifier type is passed where the other would be expected.
This PR introduces explicit `Txid` and `Wtxid` types that (if used) would cause compilation errors for such type confusion bugs.
(Only the orphanage is converted to use these types in this PR)

64d6f77907 net: put CJDNS prefix byte in a constant (Vasil Dimov)
Pull request description:
`LookupSubNet()` would treat addresses that start with `fc` as IPv6 even if `-cjdnsreachable` is set. This creates the following problems where it is called:
* `NetWhitelistPermissions::TryParse()`: otherwise `-whitelist=` fails to white list CJDNS addresses: when a CJDNS peer connects to us, it will be matched against IPv6 `fc...` subnet and the match will never succeed.
* `BanMapFromJson()`: CJDNS bans are stored as just IPv6 addresses in `banlist.json`. Upon reading from disk they have to be converted back to CJDNS, otherwise, after restart, a ban entry like (`fc00::1`, IPv6) would not match a peer (`fc00::1`, CJDNS).
* `RPCConsole::unbanSelectedNode()`: in the GUI the ban entries go through `CSubNet::ToString()` and back via `LookupSubNet()`. Then it must match whatever is stored in `BanMan`, otherwise it is impossible to unban via the GUI.
These were uncovered by https://github.com/bitcoin/bitcoin/pull/26859.
Thus, flip the result of `LookupSubNet()` to CJDNS if the network base address starts with `fc` and `-cjdnsreachable` is set. Since subnetting/masking does not make sense for CJDNS (the address is "random" bytes, like Tor and I2P, there is no hierarchy) treat `fc.../mask` as an invalid `CSubNet`.
To achieve that, `MaybeFlipIPv6toCJDNS()` has to be moved from `net` to `netbase` and thus also `IsReachable()`. In the process of moving `IsReachable()`, `SetReachable()` and `vfLimited[]` encapsulate those in a class.

7ed2b2d430 test: remove mutable global contexts in miniscript fuzzer/test (Pieter Wuille)
Pull request description:
So far, the same algorithm is used to compute an (upper bound on) the maximum witness size for both P2WSH and P2TR miniscript. That's unfortunate, because it means fee estimations for P2TR miniscript will miss out on the generic savings brought by P2TR witnesses (smaller signatures and public keys, specifically).
Fix this by making the algorithm use script context specification calculations, and add tests for it. Also included is a cleanup for the tests to avoid mutable globals, as I found it hard to reason about what exactly was being tested.

In order to exacerbate a mistake in the stack size tracking logic,
sometimes pad the witness to make the script execute at the brink of the
stack size limit. This way if the stack size is underestimated for a
script it would immediately fail `VerifyScript`.
We introduce another global that dictates the script context under which
to operate when running the target.
For miniscript_script, just consume another byte to set the context.
This should only affect existing seeds to the extent they contain a
CHECKMULTISIG. However it would not invalidate them entirely as they may
contain a NUMEQUAL or a CHECKSIGADD, and this still exercises a bit of
the parser.
For miniscript_string, reduce the string size by one byte and use the
last byte to determine the context. This is the change that i think
would invalidate the lowest number of existing seeds.
For miniscript_stable, we don't want to invalidate any seed. Instead of
creating a new miniscript_stable_tapscript, simply run the target once
for P2WSH and once for Tapscript (with the same seed).
For miniscript_smart, consume one byte before generating a pseudo-random
node to set the context. We have less regard for seed stability for this
target anyways.
In Tapscript MINIMALIF is a consensus rule, so we can rely on the fact
that the `DUP IF [X] ENDIF` will always put an exact 1 on the stack upon
satisfaction.
It is the equivalent of multi() but for Tapscript, using CHECKSIGADD
instead of CHECKMULTISIG.
It shares the same properties as multi() but for 'n', since a threshold
multi_a() may have an empty vector as the top element of its
satisfaction. It could also have the 'o' property when it only has a
single key, but in this case a 'pk()' is always preferable anyways.
We are going to introduce Tapscript support in Miniscript, for which
some of Miniscript rules and properties change (new or modified
fragments, different typing rules, different resources consumption, ..).
352d5eb2a9 test: getrawaddrman RPC (0xb10c)
da384a286b rpc: getrawaddrman for addrman entries (0xb10c)
Pull request description:
Inspired by `getaddrmaninfo` (#27511), this adds a hidden/test-only `getrawaddrman` RPC. The RPC returns information on all addresses in the address manager new and tried tables. Addrman table contents can be used in tests and during development.
The RPC result encodes the `bucket` and `position`, the internal location of addresses in the tables, in the address object's string key. This allows users to choose to consume or to ignore the location information. If the internals of the address manager implementation change, the location encoding might change too.
```
getrawaddrman
EXPERIMENTAL warning: this call may be changed in future releases.
Returns information on all address manager entries for the new and tried tables.
Result:

"address" : "str", (string) The address of the node
"port" : n, (numeric) The port number of the node
"network" : "str", (string) The network (ipv4, ipv6, onion, i2p, cjdns) of the address

Pull request description:
_This is a piece of #21878, chopped off to ease review._
Peeking at the underlying socket file descriptor of `Sock` and checkig if it is `INVALID_SOCKET` is bad encapsulation and stands in the way of testing/mocking/fuzzing.
Instead use an empty `unique_ptr` to denote that there is no valid socket where appropriate or outright remove such checks where they are not necessary.
The default constructor `Sock::Sock()` is unnecessary now after recent changes, thus remove it.

This changeset finishes the first phase of the assumeutxo project. It makes UTXO snapshots loadable via RPC (`loadtxoutset`) and adds `assumeutxo` parameters to chainparams. It contains all the remaining changes necessary to both use an assumedvalid snapshot chainstate and do a full validation sync in the background.
This may look like a lot to review, but note that
- ~200 lines are a (non-essential) demo shell script
- Many lines are functional test, documentation, and relatively dilute RPC code.
So it shouldn't be as burdensome to review as the linecount might suggest.
- **P2P**: minor changes are made to `init.cpp` and `net_processing.cpp` to make simultaneous IBD across multiple chainstates work.
- **Pruning**: implement correct pruning behavior when using a background chainstate
- **Blockfile separation**: to prevent "fragmentation" in blockfile storage, have background chainstates use separate blockfiles from active snapshot chainstates to avoid interleaving heights and impairing pruning.
- **Indexing**: some `CValidationInterface` events are given with an additional parameter, ChainstateRole, and all indexers ignore events from ChainstateRole::ASSUMEDVALID so that indexation only happens sequentially.
- Have `-reindex` properly wipe snapshot chainstates.
- **RPC**: introduce RPC commands `loadtxoutset` and (hidden) `getchainstates`.
- **Release docs & first assumeutxo commitment**: add notes and a particular assumeutxo hash value for first AU-enabled release.
- This will complete the project and allow use of UTXO snapshots for faster node bootstrap.
The next phase, if it were to be pursued, would be coming up with a way to distribute the UTXO snapshots over the P2P network.
---
### UTXO snapshots
Create your own with `./contrib/devtools/utxo_snapshot.sh`, e.g.
```shell
./contrib/devtools/utxo_snapshot.sh 788000 utxo.dat ./src/bitcoin-cli -datadir=$(pwd)/testdata`)
```

### Testing
#### For fun (~5min)
If you want to do a quick test, you can run `./contrib/devtools/test_utxo_snapshots.sh` and follow the instructions. This is mostly obviated by the functional tests, though.
#### For real (longer)
If you'd like to experience a real usage of assumeutxo, you can do that too.
I've cut a new snapshot at height 788'000 (http://img.jameso.be/utxo-788000.dat - but you can do it yourself with `./contrib/devtools/utxo_snapshot.sh` if you want). Download that, and then create a datadir for testing:
```sh
$ cd ~/src/bitcoin # or whatever
# get the snapshot
$ curl http://img.jameso.be/utxo-788000.dat > utxo-788000.dat
# you'll want to do this if you like copy/pasting
$ export AU_DATADIR=/home/${USER}/au-test # or wherever
$ mkdir ${AU_DATADIR}
$ vim ${AU_DATADIR}/bitcoin.conf
dbcache=8000 # or, you know, something high
blockfilterindex=1
coinstatsindex=1
prune=3000
logthreadnames=1
```
Obtain this branch, build it, and then start bitcoind:
```sh
$ git remote add jamesob https://github.com/jamesob/bitcoin
$ git fetch jamesob assumeutxo
$ git checkout jamesob/assumeutxo
$ ./configure $conf_args && make # (whatever you like to do here)
# start 'er up and watch the logs
$ ./src/bitcoind -datadir=${AU_DATADIR}
```
Then, in some other window, load the snapshot
```sh
$ ./src/bitcoin-cli -datadir=${AU_DATADIR} loadtxoutset $(pwd)/utxo-788000.dat
```
You'll see some log messages about headers retrieval and waiting to see the snapshot in the headers chain. Once you get the full headers chain, you'll spend a decent amount of time (~10min) loading the snapshot, checking it, and flushing it to disk. After all that happens, you should be syncing to tip in pretty short order, and you'll see the occasional `[background validation]` log message go by.
In yet another window, you can check out chainstate status with
```sh
$ ./src/bitcoin-cli -datadir=${AU_DATADIR} getchainstates
```
as well as usual favorites like `getblockchaininfo`.

Exposing address manager table entries in a hidden RPC allows to introspect
addrman tables in tests and during development.
As response JSON object the following FORMAT1 is choosen:
{
"table": {
"<bucket>/<position>": { "address": "..", "port": .., ... },
"<bucket>/<position>": { "address": "..", "port": .., ... },
"<bucket>/<position>": { "address": "..", "port": .., ... },
...
}
}
An alternative would be FORMAT2
{
"table": {
"bucket": {
"position": { "address": "..", "port": .., ... },
"position": { "address": "..", "port": .., ... },
..
},
"bucket": {
"position": { "address": "..", "port": .., ... },
..
},
}
}
FORMAT1 and FORMAT2 have different encodings for the location of the
address in the address manager. While FORMAT2 might be easier to process
for downstream tools, it also mimics internal addrman mappings, which
might change at some point. Users not interested in the address location
can ignore the location key. They don't have to adapt to a new RPC
response format, when the internal addrman layout changes. Additionally,
FORMAT1 is also slightly easier to to iterate in downstream tools. The
RPC response-building implemenation complexcity is lower with FORMAT1
as we can more easily build a "<bucket>/<position>" key than a multiple
"bucket" objects with multiple "position" objects (FORMAT2).

262ab8ef78 Add package evaluation fuzzer (Greg Sanders)
Pull request description:
This fuzzer target caught the issue in https://github.com/bitcoin/bitcoin/pull/28251 within 5 minutes on master branch, and an additional issue which I've applied a preliminary patch to cover.
Fuzzer target does the following:
1) Picks mempool confgs, including max package size, count, mempool size, etc
2) Generates 1 to 26 transactions with arbitrary coins/fees, the first N-1 spending only confirmed outpoints
3) Nth transaction, if >1, sweeps all unconfirmed outpoints in mempool
4) If N==1, it may submit it through single-tx submission path, to allow for more interesting topologies
5) Otherwise submits through package submission interface
6) Repeat 1-5 a few hundred times per mempool instance
In other words, it ends up building chains of txns in the mempool using parents-and-children packages, which is currently the topology supported on master.
The test itself is a direct rip of tx_pool.cpp, with a number of assertions removed because they were failing for unknown reasons, likely due to the notification changes of single tx submission to package, which is used to track addition/removal of transactions in the test. I'll continue working on re-adding these assertions for further invariant testing.

fa389d902f refactor: Drop unused fclose() from BufferedFile (MarcoFalke)
Pull request description:
This is required for https://github.com/bitcoin/bitcoin/pull/28052, but makes sense on its own, because offloading logic to `CAutoFile` instead of re-implementing it allows to delete code and complexity.

28bac81a34 test: add functional test for getaddrmaninfo (stratospher)
c8eb8dae51 rpc: Introduce getaddrmaninfo for count of addresses stored in new/tried table (stratospher)
Pull request description:
implements https://github.com/bitcoin/bitcoin/issues/26907. split off from #26988 to keep RPC, CLI discussions separate.
This PR introduces a new RPC `getaddrmaninfo`which returns the count of addresses in the new/tried table of a node's addrman broken down by network type. This would be useful for users who want to see the distribution of addresses from different networks across new/tried table in the addrman.
```jsx
$ getaddrmaninfo
Result:
{ (json object) json object with network type as keys
"network" : { (json object) The network (ipv4, ipv6, onion, i2p, cjdns)
"new" : n, (numeric) number of addresses in new table
"tried" : n, (numeric) number of addresses in tried table
"total" : n (numeric) total number of addresses in both new/tried tables from a network
},
...
}
```
### additional context from [original PR](https://github.com/bitcoin/bitcoin/pull/26988)
1. network coverage tests were skipped because there’s a small chance that addresses from different networks could hash to the same bucket and cause count of different network addresses in the tests to fail. see https://github.com/bitcoin/bitcoin/pull/26988#discussion_r1137596851.
2. #26988 uses this RPC in -addrinfo CLI. Slight preference for keeping the RPC hidden since this info will mostly be useful to only super users. see https://github.com/bitcoin/bitcoin/pull/26988#discussion_r1173964808.

ad0c469d98 wallet: Use CTxDestination in CRecipient rather than scriptPubKey (Andrew Chow)
07d3bdf4eb Add PubKeyDestination for P2PK scripts (Andrew Chow)
1a98a51c66 Allow CNoDestination to represent a raw script (Andrew Chow)
8dd067088d Make WitnessUnknown members private (Andrew Chow)
Pull request description:
For silent payments, we want to provide a `SilentPaymentsDestination` to be used as the recipient, which requires `CRecipient` to use something other than just the `scriptPubKey` as we cannot know the output script for a silent payment prior to transaction creation. `CTxDestination` seems like the obvious place to add a `SilentPaymentsDestination` as it is our internal representation of an address.
In order to still allow paying to arbitrary scriptPubKeys (e.g. for data carrier outputs, or the user hand crafted a raw transaction that they have given to `fundrawtransaction`), `CNoDestination` is changed to contain raw scripts.
Additionally, P2PK scripts are now interpreted as a new `PubKeyDestination` rather than `PKHash`. This results in some things that would have given an address for P2PK scripts to no longer do so. This is arguably more correct.
`ExtractDestination`'s behavior is slightly changed for the above. It now returns `true` for those destinations that have addresses, so P2PK scripts now result in `false`. Even though it returns false for `CNoDestination`, the script will now be included in that `CNoDestination`.
Builds on #28244
