5c446784b1 rpc: improve getnodeaddresses help (Jon Atack)
1b9189866a rpc: simplify/constify getnodeaddresses code (Jon Atack)
3bb6e7b655 rpc: add network field to rpc getnodeaddresses (Jon Atack)
Pull request description:
This patch adds a network field to RPC `getnodeaddresses`, which is useful on its own, particularly with the addition of new networks like I2P and others in the future, and which I also found helpful for adding a new CLI command as a follow-up to this pull that calls `getnodeaddresses` and needs to know the network of each address.
While here, also improve the `getnodeaddresses` code and help.
```

$ bitcoin-cli help getnodeaddresses
getnodeaddresses ( count )
Return known addresses, which can potentially be used to find new nodes in the network.
Arguments:
1. count (numeric, optional, default=1) The maximum number of addresses to return. Specify 0 to return all known addresses.
Result:
[ (json array)
{ (json object)
"time" : xxx, (numeric) The UNIX epoch time when the node was last seen
"services" : n, (numeric) The services offered by the node
"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) the node connected through
},
...
]
```
Future idea: allow passing `getnodeaddresses` a network (or networks) as an argument to return only addresses in that network.

a97a9298ce Test that signrawtx works when a signed CSV and CLTV inputs are present (Andrew Chow)
6965456c10 Introduce DeferringSignatureChecker and inherit with SignatureExtractor (Andrew Chow)
Pull request description:
Previously SignatureExtractorChecker took a MutableTransactionSignatureChecker and passed through function calls to that. However not all functions were implemented so not everything passed through as it should have. To solve this, SignatureExctractorChecker now implements all of those functions via a new class - DeferredSignatureChecker. DeferredSignatureChecker is introduced to allow for future signature checkers which use another SignatureChecker but need to be able to do somethings outside of just the signature checking.

90ae3d8ca6 doc: Add release notes for -deprecatedrpc=addresses and bitcoin-tx (Michael Dietz)
085b3a7299 rpc: deprecate `addresses` and `reqSigs` from rpc outputs (Michael Dietz)
Pull request description:
Considering the limited applicability of `reqSigs` and the confusing output of `1` in all cases except bare multisig, the `addresses` and `reqSigs` outputs are removed for all rpc commands.
1) add a new sane "address" field (for outputs that have an identifiable address, which doesn't include bare multisig)
2) with -deprecatedrpc: leave "reqSigs" and "addresses" intact (with all weird/wrong behavior they have now)
3) without -deprecatedrpc: drop "reqSigs" and "addresses" entirely always.
Note: Some light refactoring done to allow us to very easily delete a few chunks of code (marked with TODOs) when we remove this deprecated behavior.
Using `IsDeprecatedRPCEnabled` in core_write.cpp caused some circular dependencies involving core_io
Circular dependencies were caused by rpc/util unnecessarily importing node/coinstats and node/transaction. Really what rpc/util needs are some fundamental type/helper-function definitions. So this was cleaned up to make more sense.
This fixes#20102.

beead33a21 [test] no send feefilters when txrelay is turned off (glozow)
18a9b27dd6 p2p: Don't send FEEFILTER in blocksonly mode (Martin Zumsande)
Pull request description:
The purpose of FEEFILTER messages (BIP 133) is to inform our peers that we do not want transactions below a specified fee rate.
In blocksonly mode, we do not want our peer to send us any transactions at all (and will disconnect if a peer still sends a transaction INV or TX).
Therefore, I don't think that it makes sense to send FEEFILTER messages every 10 minutes on average in blocksonly mode - this PR disables it.
Note that on block-relay-only connections, FEEFILTER is already disabled, just not in blocksonly mode.

39a9ec579f Unconditionally check for fRelay field in test framework (Troy Giorshev)
Pull request description:
picking up #20411 (rebased onto master)
There is a discrepancy in the implementation of our p2p protocol between
bitcoind and the testing framework. The fRelay field is an optional
field at the end of a version message as of protocol version 70001.
However, when deserializing a message in bitcoind, we don't check the
version to see if it should have an fRelay field or not. Instead, we
unconditionally attempt to deserialize into the field.
This commit brings the testing framework in line with the implementation
in core.
This matters for a version message with the following fields:
Version = 60000
fRelay = 1
Bitcoind would deserialize this into a version message with
Version=60000 and fRelay=1, whereas (before this commit) our testing
framework would deserialize this into a version message with
Version=60000 and fRelay=0.

48a0319bab Add a test that selects too large if BnB is used (Andrew Chow)
3e69939b78 Fail if maximum weight is too large (Andrew Chow)
51e2cd322c Have CalculateMaximumSignedTxSize also compute tx weight (Andrew Chow)
Pull request description:
Currently the `Transaction too large` is calculated on the transaction that is returned from `CreateTransaction`. This does not make sense for when `CreateTransaction` is being used for `fundrawtransaction` as no signing occurs so the final returned transaction is missing signatures. Thus users may successfully fund a transaction but fail to broadcast it after it has been fully signed.
So instead we should figure out whether the transaction we are funding will be too large after it is signed. We can do this by having `CalculateMaximumSignedTxSize` also return the transaction weight and then comparing that weight against the maximum weight.

Pull request description:
Add I2P support by using the [I2P SAM](https://geti2p.net/en/docs/api/samv3) protocol. Unlike Tor, for incoming connections we get the I2P address of the peer (and they also receive ours when we are the connection initiator).
Two new options are added:
```
-i2psam=<ip:port>
I2P SAM proxy to reach I2P peers and accept I2P connections (default:
none)
-i2pacceptincoming
If set and -i2psam is also set then incoming I2P connections are
accepted via the SAM proxy. If this is not set but -i2psam is set
then only outgoing connections will be made to the I2P network.
Ignored if -i2psam is not set. Notice that listening for incoming
I2P connections is done through the SAM proxy, not by binding to
a local address and port (default: true)
```
# Overview of the changes
## Make `ReadBinary()` and `WriteBinary()` reusable
We would need to dump the I2P private key to a file and read it back later. Move those two functions out of `torcontrol.cpp`.

## Split `CConnman::AcceptConnection()`
Most of `CConnman::AcceptConnection()` is agnostic of how the socket was accepted. The other part of it deals with the details of the `accept(2)` system call. Split those so that the protocol-agnostic part can be reused if we accept a socket by other means.
```
net: check for invalid socket earlier in CConnman::AcceptConnection()
net: get the bind address earlier in CConnman::AcceptConnection()
net: isolate the protocol-agnostic part of CConnman::AcceptConnection()
net: avoid unnecessary GetBindAddress() call
```
## Implement the I2P [SAM](https://geti2p.net/en/docs/api/samv3) protocol (not all of it)
Just the parts that would enable us to make outgoing and accept incoming I2P connections.
```
net: extend CNetAddr::SetSpecial() to support I2P
net: move the constant maxWait out of InterruptibleRecv()
net: dedup MSG_NOSIGNAL and MSG_DONTWAIT definitions
net: extend Sock::Wait() to report a timeout
net: extend Sock with methods for robust send & read until terminator
net: extend Sock with a method to check whether connected
net: implement the necessary parts of the I2P SAM protocol
```
## Use I2P SAM to connect to and accept connections from I2P peers
Profit from all of the preceding commits.
```
init: introduce I2P connectivity options
net: add I2P to the reachability map
net: make outgoing I2P connections from CConnman
net: accept incoming I2P connections from CConnman
net: recognize I2P from ParseNetwork() so that -onlynet=i2p works
net: Do not skip the I2P network from GetNetworkNames()
```

8a8c6383f6 zmq test: fix sync-up by matching notification to generated block (Sebastian Falbesoner)
Pull request description:
This is a follow-up PR for #21008, fixes#21216.
In the course of investigating the problem with jnewbery (analyzing the Cirrus log https://cirrus-ci.com/task/4660108304056320), it turned out that the "sync up" procedure of repeatedly generating a block and waiting for a notification with timeout is too brittle in its current form, as the following scenario could happen:
- generate block A
- receive notification, timeout happens => repeat procedure
- generate block B
- node publishes block A notification
- receive notification, we receive the one caused by block A (!!!) => sync-up procedure is completed
- node publishes block B notification
- the actual test starts
- on the first notification reception, the one caused by block B is received, rather than the one actually caused by test code => assertion failure
This change in the PR ensures that after each test block generation, we wait for the notification that is actually caused by that block and ignore others from possibly earlier blocks. The matching is kind of ugly, it assumes that one out of four components in the block is contained in the notification: the block hash, the tx id, the raw block data or the raw transaction data. (Unfortunately we have to support all publisher topics.)
I'm aware that this is quite a lot of code now only for establishing a robust test setup. OTOH I wouldn't know of a better method right now, suggestions are very welcome.
Note for potential reviewers: for both reproducing the issue on master branch and verifying on PR branch, one can simply generate two blocks in the sync-up procedure rather than one.

So that help texts include "i2p" in:
* `./bitcoind -help` (in `-onlynet` description)
* `getpeerinfo` RPC
* `getnetworkinfo` RPC
Co-authored-by: Jon Atack <jon@atack.com>
Introduce two new options to reach the I2P network:
* `-i2psam=<ip:port>` point to the I2P SAM proxy. If this is set then
the I2P network is considered reachable and we can make outgoing
connections to I2P peers via that proxy. We listen for and accept
incoming connections from I2P peers if the below is set in addition to
`-i2psam=<ip:port>`
* `-i2pacceptincoming` if this is set together with `-i2psam=<ip:port>`
then we accept incoming I2P connections via the I2P SAM proxy.
