b82f7843ff Use peeking_take_while in BlockReplayer (#4803)
## Issue Addressed

While reviewing #4801 I noticed that our use of `take_while` in the block replayer means that if a state root iterator _with gaps_ is provided, some additonal state roots will be dropped unnecessarily. In practice the impact is small, because once there's _one_ state root miss, the whole tree hash cache needs to be built anyway, and subsequent misses are less costly. However this was still a little inefficient, so I figured it's better to fix it.

## Proposed Changes

Use [`peeking_take_while`](https://docs.rs/itertools/latest/itertools/trait.Itertools.html#method.peeking_take_while) to avoid consuming the next element when checking whether it satisfies the slot predicate.

## Additional Info

There's a gist here that shows the basic dynamics in isolation: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=40b623cc0febf9ed51705d476ab140c5. Changing the `peeking_take_while` to a `take_while` causes the assert to fail. Similarly I've added a new test `block_replayer_peeking_state_roots` which fails if the same change is applied inside `get_state_root`.

4b619c63d7 Exit aggregation step early if no validator is aggregator (#4774)
## Issue Addressed

Closes https://github.com/sigp/lighthouse/issues/4712

## Proposed Changes

Exit aggregation step early if no validator is aggregator. This avoids an unnecessary request to the beacon node and more importantly fixes noisy errors if Lighthouse VC is used with other clients such as Lodestar and Prysm.

6ec649a4e2 Optimise head block root API (#4799)
## Issue Addressed

We've had a report of sync committee performance suffering with the beacon processor HTTP API prioritisations.

## Proposed Changes

Increase the priority of `/eth/v1/beacon/blocks/head/root` requests, which are used by the validator client to form sync committee messages, here:

441fc1691b/validator_client/src/sync_committee_service.rs (L181-L188)

Additionally, avoid loading the blinded block in all but the `block_id=block_root` case. I'm not sure why we were doing this previously, I suspect it was just an oversight during the implementation of the `finalized` status on API requests.

## Additional Info

I think this change should have minimal negative impact as:

- The block root endpoint is quick to compute (a few ms max).
- Only the priority of `head` requests is increased. Analytical processes that are making lots of block root requests for past slots are unable to DoS the beacon processor, as their requests will still be processed after attestations.

5bab9b866e Don't downscore peers on duplicate blocks (#4791)
## Issue Addressed

N/A

## Proposed Changes

We were currently downscoring a peer for sending us a block that we already have in fork choice. This is unnecessary as we get duplicates in lighthouse only when
1. We published the block, so the block is already in fork choice
2. We imported the same block over rpc

In both scenarios, the peer who sent us the block over gossip is not at fault.

This isn't exploitable as valid duplicates will get dropped by the gossipsub duplicate filter

f11884ccdb enforce non zero enr ports (#4776)
## Issue Addressed

Right now lighthouse accepts zero as enr ports. Since enr ports should be reachable, zero ports should be rejected here

## Proposed Changes

- update the config to use `NonZerou16` as an ENR port for all enr-related fields.
- the enr builder from config now sets the enr to the listening port only if the enr port is not already set (prev behaviour) and the listening port is not zero (new behaviour)
- reject zero listening ports when used with `enr-match`. 
- boot node now rejects listening port as zero, since those are advertised.
- generate-bootnode-enr also rejected zero listening ports for the same reason.
- update local network scripts

## Additional Info

Unrelated, but why do we overwrite `enr-x-port` values with listening ports if `enr-match` is present? we prob should only do this for enr values that are not already set.

0dc95a1d37 PeerManager: move the check for banned peers from connection_established (#4569)
## Issue Addressed
https://github.com/sigp/lighthouse/issues/4543
## Proposed Changes
- Removes `NotBanned` from `BanResult`, implements `Display` and `std::error::Error` for `BanResult` and changes `ban_result` return type to `Option<BanResult>` which helps returning `BanResult` on `handle_established_inbound_connection`  
- moves the check from for banned peers from `on_connection_established` to `handle_established_inbound_connection` to start addressing #4543.
- Removes `allow_block_list` as it's now redundant? Not sure about this one but if `PeerManager` keeps track of the banned peers, no need to send a `Swarm` event for `alow_block_list` to also keep that list right? 
 
## Questions

-  #4543 refers:
>  More specifically, implement the connection limit behaviour inside the peer manager.

@AgeManning do you mean copying `libp2p::connection_limits::Behaviour`'s code into `PeerManager`/ having it as an inner `NetworkBehaviour` of `PeerManager`/other? If it's the first two, I think it probably makes more sense to have it as it is as it's less code to maintain.

> Also implement the banning of peers inside the behaviour, rather than passing messages back up to the swarm.

I tried to achieve this, but we still need to pass the `PeerManagerEvent::Banned` swarm event as `DiscV5` handles it's node and ip management internally and I did not find a method to query if a peer is banned. Is there anything else we can do from here?

3397612160/beacon_node/lighthouse_network/src/discovery/mod.rs (L931-L940)

Same as the question above, I did not find a way to check if `DiscV5` has the peer banned, so that we could check here and avoid sending `Swarm` events

3397612160/beacon_node/lighthouse_network/src/peer_manager/network_behaviour.rs (L168-L178)

Is there a chance we try to dial a peer that has been banned previously? 

Thanks!

7605494791 Use only lighthouse types in the mock builder (#4793)
## Proposed Changes

- only use LH types to avoid build issues
- use warp instead of axum for the server to avoid importing the dep

## Additional Info

- wondering if we can move the `execution_layer/test_utils` to its own crate and import it as a dev dependency
- this would be made easier by separating out our engine API types into their own crate so we can use them in the test crate
- or maybe we can look into using reth types for the engine api if they are in their own crate

8a1b77bf89 Ultra Fast Super Slick CI (#4755)
Attempting to improve our CI speeds as its recently been a pain point.

Major changes:

 - Use a github action to pull stable/nightly rust rather than building it each run
 - Shift test suite to `nexttest` https://github.com/nextest-rs/nextest for CI
 
 UPDATE:

So I've iterated on some changes, and although I think its still not optimal I think this is a good base to start from. Some extra things in this PR:
- Shifted where we pull rust from. We're now using this thing: https://github.com/moonrepo/setup-rust . It's got some interesting cache's built in, but was not seeing the gains that Jimmy managed to get. In either case tho, it can pull rust, cargofmt, clippy, cargo nexttest all in < 5s. So I think it's worthwhile. 
- I've grouped a few of the check-like tests into a single test called `code-test`. Although we were using github runners in parallel which may be faster, it just seems wasteful. There were like 4-5 tests, where we would pull lighthouse, compile it, then run an action, like clippy, cargo-audit or fmt. I've grouped these into a single action, so we only compile lighthouse once, then in each step we run the checks. This avoids compiling lighthouse like 5 times.
- Ive made doppelganger tests run on our local machines to avoid pulling foundry, building and making lcli which are all now baked into the images. 
- We have sccache and do not incremental compile lighthouse

Misc bonus things:
- Cargo update
- Fix web3 signer openssl keys which is required after a cargo update
- Use mock_instant in an LRU cache test to avoid non-deterministic test
- Remove race condition in building web3signer tests

There's still some things we could improve on. Such as downloading the EF tests every run and the web3-signer binary, but I've left these to be out of scope of this PR. I think the above are meaningful improvements.

dcd69dfc62 Move dependencies to workspace (#4650)
## Issue Addressed

Synchronize dependencies and edition on the workspace `Cargo.toml`

## Proposed Changes

with https://github.com/rust-lang/cargo/issues/8415 merged it's now possible to synchronize details on the workspace `Cargo.toml` like the metadata and dependencies.
By only having dependencies that are shared between multiple crates aligned on the workspace `Cargo.toml` it's easier to not miss duplicate versions of the same dependency and therefore ease on the compile times.

## Additional Info
this PR also removes the no longer required direct dependency of the `serde_derive` crate.

should be reviewed after https://github.com/sigp/lighthouse/pull/4639 get's merged.

fe3bd03234 Fix local testnet to generate keys in the correct folders (#4752)
Fix local testnet to generate keys in the correct folders when `BN_COUNT` and `VC_COUNT` don't match.

The current script place the generated validator keys in validator folders based on the `BN_COUNT` config, e.g. `node_1/validators`, `node_2/validators`..etc. We should be using `VC_COUNT` here instead, otherwise the number of validator clients may not match the number of directories generated, and would result in either:
1. a VC not having any keys  (when `BN_COUNT` < `VC_COUNT`)
2. a validator key directory not being used (when `BN_COUNT` > `VC_COUNT`).

5a35278aea Add more checks and logging before genesis (#4730)
## Proposed Changes

This PR adds more logging prior to genesis, particularly on networks that start with execution enabled.

There are new checks using `eth_getBlockByHash/Number` to verify that the genesis state's `latest_execution_payload_header` matches the execution node's genesis block.

The first commit also runs the merge-readiness/Capella-readiness checks prior to genesis. This has two effects:

- Give more information on the execution node's status and its readiness for genesis.
- Prevent the `el_offline` status from being set on `/eth/v1/node/syncing`, which previously caused the VC to complain loudly.

I would like to include this for the Holesky reboot. It would have caught the misconfig that doomed the first Holesky.

## Additional Info

- Geth doesn't serve payload bodies prior to genesis, which is why we use the legacy methods. I haven't checked with other ELs yet.
- Currently this is logging errors with _Capella_ genesis states generated by `ethereum-genesis-generator` because the `withdrawals_root` is not set correctly (it is 0x0). This is not a blocker for Holesky, as it starts from Bellatrix (Pari is investigating).

1e9925435e Reuse fork choice read lock instead of re-acquiring it immediately (#4688)
## Issue Addressed

I went through the code base and look for places where we acquire fork choice locks (after the deadlock bug was found and fixed in #4687), and discovered an instance where we re-acquire a lock immediately after dropping it. This shouldn't cause deadlock like the other issue, but is slightly less efficient.
