Anchor currently depends on `lighthouse_network` for a few types and utilities that live within. As we use our own libp2p behaviours, we actually do not use the core logic in that crate. This makes us transitively depend on a bunch of unneeded crates (even a whole separate libp2p if the versions mismatch!)
Move things we require into it's own lightweight crate.

This method is a footgun because it truncates the list. It is the source of a recent bug:
- https://github.com/sigp/lighthouse/pull/7927
- Delete uses of `RuntimeVariableList::from_vec` and replace them with `::new` which does validation and can fail.
- Propagate errors where possible, unwrap in tests and use `expect` for obviously-safe uses (in `chain_spec.rs`).
Adds the required boilerplate code for the Gloas (Glamsterdam) hard fork. This allows PRs testing Gloas-candidate features to test fork transition.
This also includes de-duplication of post-Bellatrix readiness notifiers from #6797 (credit to @dapplion)
Fixes#7926
This was a bug I introduced in #7890 and @pawanjay176 noticed it on some running nodes, and added a rpc test to confirm it.
The culprit is this line, where I failed to fill the vec to it's max size, so it doesn't calculate the max size properly, resulting in all `DataColumnByRoot` requests exceeding the max size during validation:
d24a6d2a45/consensus/types/src/chain_spec.rs (L1984)
The PR fixes this and includes new regression tests for this fix.
Fix Clippy for recently released Rust 1.90 beta. There may be more changes required when Rust 1.89 stable is released in a few days, but possibly not 🤞
Closes#7467.
This PR primarily addresses [the P2P changes](https://github.com/ethereum/EIPs/pull/9840) in [fusaka-devnet-2](https://fusaka-devnet-2.ethpandaops.io/). Specifically:
* [the new `nfd` parameter added to the `ENR`](https://github.com/ethereum/EIPs/pull/9840)
* [the modified `compute_fork_digest()` changes for every BPO fork](https://github.com/ethereum/EIPs/pull/9840)
90% of this PR was absolutely hacked together as fast as possible during the Berlinterop as fast as I could while running between Glamsterdam debates. Luckily, it seems to work. But I was unable to be as careful in avoiding bugs as I usually am. I've cleaned up the things *I remember* wanting to come back and have a closer look at. But still working on this.
Progress:
* [x] get it working on `fusaka-devnet-2`
* [ ] [*optional* disconnect from peers with incorrect `nfd` at the fork boundary](https://github.com/ethereum/consensus-specs/pull/4407) - Can be addressed in a future PR if necessary
* [x] first pass clean-up
* [x] fix up all the broken tests
* [x] final self-review
* [x] more thorough review from people more familiar with affected code
Resolves#6767
This PR implements a basic version of validator custody.
- It introduces a new `CustodyContext` object which contains info regarding number of validators attached to a node and the custody count they contribute to the cgc.
- The `CustodyContext` is added in the da_checker and has methods for returning the current cgc and the number of columns to sample at head. Note that the logic for returning the cgc existed previously in the network globals.
- To estimate the number of validators attached, we use the `beacon_committee_subscriptions` endpoint. This might overestimate the number of validators actually publishing attestations from the node in the case of multi BN setups. We could also potentially use the `publish_attestations` endpoint to get a more conservative estimate at a later point.
- Anytime there's a change in the `custody_group_count` due to addition/removal of validators, the custody context should send an event on a broadcast channnel. The only subscriber for the channel exists in the network service which simply subscribes to more subnets. There can be additional subscribers in sync that will start a backfill once the cgc changes.
TODO
- [ ] **NOT REQUIRED:** Currently, the logic only handles an increase in validator count and does not handle a decrease. We should ideally unsubscribe from subnets when the cgc has decreased.
- [ ] **NOT REQUIRED:** Add a service in the `CustodyContext` that emits an event once `MIN_EPOCHS_FOR_BLOB_SIDECARS_REQUESTS ` passes after updating the current cgc. This event should be picked up by a subscriber which updates the enr and metadata.
- [x] Add more tests
Currently `test_delayed_rpc_response` is flaky (possibly specific to Windows?), but I'm not sure why.
Enabled stdout logging in rpc_tests. Note that in nextest, std output is only displayed when a test fails.

### `Is there already an active request with the same protocol?`
This check is not performed in `Before`. This is taken from the PR in the consensus-spec, which proposes updates regarding rate limiting and response timeout.
https://github.com/ethereum/consensus-specs/pull/3767/files
> The requester MUST NOT make more than two concurrent requests with the same ID.
The PR mentions the requester side. In this PR, I introduced the `ActiveRequestsLimiter` for the `responder` side to restrict more than two requests from running simultaneously on the same protocol per peer. If the limiter disallows a request, the responder sends a rate-limited error and penalizes the requester.
### `Rate limit reached?` and `Wait until tokens are regenerated`
UPDATE: I moved the limiter logic to the behaviour side. https://github.com/sigp/lighthouse/pull/5923#issuecomment-2379535927
~~The rate limiter is shared between the behaviour and the handler. (`Arc<Mutex<RateLimiter>>>`) The handler checks the rate limit and queues the response if the limit is reached. The behaviour handles pruning.~~
~~I considered not sharing the rate limiter between the behaviour and the handler, and performing all of these either within the behaviour or handler. However, I decided against this for the following reasons:~~
- ~~Regarding performing everything within the behaviour: The behaviour is unable to recognize the response protocol when `RPC::send_response()` is called, especially when the response is `RPCCodedResponse::Error`. Therefore, the behaviour can't rate limit responses based on the response protocol.~~
- ~~Regarding performing everything within the handler: When multiple connections are established with a peer, there could be multiple handlers interacting with that peer. Thus, we cannot enforce rate limiting per peer solely within the handler. (Any ideas? 🤔 )~~
Resolves#6811
Rename `GOSSIP_MAX_SIZE` to `MAX_PAYLOAD_SIZE` and remove `MAX_CHUNK_SIZE` in accordance with the spec.
The spec also "clarifies" the message size limits at different levels. The rpc limits are equivalent to what we had before imo.
The gossip limits have additional checks.
I have gotten rid of the `is_bellatrix_enabled` checks that used a lower limit (1mb) pre-merge. Since all networks we run start from the merge, I don't think this will break any setups.
I've been working at updating another library to latest Lighthouse and got very confused with RPC request Ids.
There were types that had fields called `request_id` and `id`. And interchangeably could have types `PeerRequestId`, `rpc::RequestId`, `AppRequestId`, `api_types::RequestId` or even `Request.id`.
I couldn't keep track of which Id was linked to what and what each type meant.
So this PR mainly does a few things:
- Changes the field naming to match the actual type. So any field that has an `AppRequestId` will be named `app_request_id` rather than `id` or `request_id` for example.
- I simplified the types. I removed the two different `RequestId` types (one in Lighthouse_network the other in the rpc) and grouped them into one. It has one downside tho. I had to add a few unreachable lines of code in the beacon processor, which the extra type would prevent, but I feel like it might be worth it. Happy to add an extra type to avoid those few lines.
- I also removed the concept of `PeerRequestId` which sometimes went alongside a `request_id`. There were times were had a `PeerRequest` and a `Request` being returned, both of which contain a `RequestId` so we had redundant information. I've simplified the logic by removing `PeerRequestId` and made a `ResponseId`. I think if you look at the code changes, it simplifies things a bit and removes the redundant extra info.
I think with this PR things are a little bit easier to reasonable about what is going on with all these RPC Ids.
NOTE: I did this with the help of AI, so probably should be checked
N/A
In https://github.com/sigp/lighthouse/pull/6329 we changed `max_blobs_per_block` from a preset to a config value.
We weren't using the right value based on fork in that PR. This is a follow up PR to use the fork dependent values.
In the proces, I also updated other places where we weren't using fork dependent values from the ChainSpec.

## Issue Addressed
#4402
## Proposed Changes
This PR adds QUIC support to Lighthouse. As this is not officially spec'd this will only work between lighthouse <-> lighthouse connections. We attempt a QUIC connection (if the node advertises it) and if it fails we fallback to TCP.
This should be a backwards compatible modification. We want to test this functionality on live networks to observe any improvements in bandwidth/latency.
NOTE: This also removes the websockets transport as I believe no one is really using it. It should be mentioned in our release however.

## Issue Addressed
Addresses [#4401](https://github.com/sigp/lighthouse/issues/4401)
## Proposed Changes
Shift some constants into ```ChainSpec``` and remove the constant values from code space.
## Additional Info
I mostly used ```MainnetEthSpec::default_spec()``` for getting ```ChainSpec```. I wonder Did I make a mistake about that.

## Issue Addressed
Upgrade libp2p to v0.52
## Proposed Changes
- **Workflows**: remove installation of `protoc`
- **Book**: remove installation of `protoc`
- **`Dockerfile`s and `cross`**: remove custom base `Dockerfile` for cross since it's no longer needed. Remove `protoc` from remaining `Dockerfiles`s
- **Upgrade `discv5` to `v0.3.1`:** we have some cool stuff in there: no longer needs `protoc` and faster ip updates on cold start
- **Upgrade `prometheus` to `0.21.0`**, now it no longer needs encoding checks
- **things that look like refactors:** bunch of api types were renamed and need to be accessed in a different (clearer) way
- **Lighthouse network**
- connection limits is now a behaviour
- banned peers no longer exist on the swarm level, but at the behaviour level
- `connection_event_buffer_size` now is handled per connection with a buffer size of 4
- `mplex` is deprecated and was removed
- rpc handler now logs the peer to which it belongs
## Additional Info
Tried to keep as much behaviour unchanged as possible. However, there is a great deal of improvements we can do _after_ this upgrade:
- Smart connection limits: Connection limits have been checked only based on numbers, we can now use information about the incoming peer to decide if we want it
- More powerful peer management: Dial attempts from other behaviours can be rejected early
- Incoming connections can be rejected early
- Banning can be returned exclusively to the peer management: We should not get connections to banned peers anymore making use of this
- TCP Nat updates: We might be able to take advantage of confirmed external addresses to check out tcp ports/ips
