Fixes #30251

This PR sets a max length for cyphertext in `ConsumeRandomLengthByteVector`. I set 64, should be enough, I couldn't see anything greater than 48 in practice tbh.

ACK 60a753b7b38fbe89494f8df66f13a84f28af244b

Tested in an ubuntu docker container with local ipv6 but not external ipv6:

```
# ip address | grep inet
inet 127.0.0.1/8 scope host lo
inet6 ::1/128 scope host
inet 172.17.0.2/16 brd 172.17.255.255 scope global eth0
```

Confirmed the `feature_proxy` test fails without the patch. Added extra logging to confirm the error:

```
getaddrinfo: ::1 error: Address family for hostname not supported
```

With the patch, `getad

Might consider using `&` here since we're dealing with bitfield flags and not absolute values

You could check specifically for `EAI_FAMILY` and then only recheck without `AI_ADDRCONFIG` in that condition. I think the code you have now will always check everything twice, but ignore duplicates?

Rudimentary idea: insert the entry in `CConnman::m_nodes` just before `PushVersion()`.

```cpp
void PeerManagerImpl::InitializeNode(CNode& node, ServiceFlags our_services)
{
...
// void CConnman::NodesAppend() { WITH_LOCK(m_nodes_mutex, m_nodes.push_back(node)); }
m_connman.NodesAppend(node);
if (!node.IsInboundConn()) {
PushNodeVersion(node, *peer);
}
}
```

or, same idea but implement by splitting the `PushNodeVersion()` bit away from `InitializeNode()`:

Yes, it will return something other than `MempoolAcceptResult::ResultType::VALID`. Would happen as well if a conflicting transaction is mined in the meantime.

@vasild is it possible that in the intermittent case, some other test running in parallel has a process is listening on port 60000? So we connect OK but fail the i2p handshake?

(https://github.com/bitcoin/bitcoin/issues/30368#issuecomment-2200639857)
Looks to me like this is an actual bug that could happen in the real network when making an automatic outbound connection to yourself (where the `opencon` thread instead of a `httpworker` thread opens the connection, whereas the `net` thread accepts connection in both cases), so it's probably not just a ci/test failure?!

Maybe a workable fix would be to take the `PushNodeVersion` call out of `InitializeNode` and call it separately after having added the node to `m_nodes` (which would mean add

Yes, it's possible. I just started a server with `python3 -m http.server 60000` and ran the test (from master branch), I got:

There is some layer separation between `net`/`CConnman` and `net_processing`/`PeerManager` which I am trying not to blur too much. The lower `net` level only knows about connections and things like "I need to open N connections of type X". It does not know anything about transactions, or P2P messages which are handled by the `net_processing` layer.

The constant `NUM_PRIVATE_BROADCAST_PER_TX` (_send a transaction to this many peers_) belongs to the `net_processing` layer. Calling this `NumToOp

Thanks AJ, it's great to get specific and find out what actual problems you are concerned about, before coming to the conclusion that it is too difficult to remove one hard dependency on global shared state, and therefore we should resort to workarounds such as running code in multiple processes, or finding ways to reset the state and coordinate access to it.

Concept ACK.

I was tacking this today (missed this PR as GH search for "sse" yielded no results 🤦🏼‍♂️ )

First I tried re-implementing @luke-jr previous approach, but refactoring into macros: https://github.com/bitcoin/bitcoin/commit/cdaa9bfd6e63dc675cdd27e6d586f69423ee1748

Whilst this works well-enough, it didn't particularly fix https://github.com/bitcoin/bitcoin/issues/28864 in my opinion, so I tried https://github.com/bitcoin/bitcoin/compare/master...willcl-ark:bitcoin:detect-sse4.
