98a9626ef5 Bump the MSRV to 1.62 and using #[derive(Default)] on enums (#3304)
## Issue Addressed

N/A

## Proposed Changes

Since Rust 1.62, we can use `#[derive(Default)]` on enums.  

https://blog.rust-lang.org/2022/06/30/Rust-1.62.0.html#default-enum-variants

There are no changes to functionality in this PR, just replaced the `Default` trait implementation with `#[derive(Default)]`.

1f54e10b7b Do not interpret "latest valid hash" as identifying a valid hash (#3327)
## Issue Addressed

NA

## Proposed Changes

After some discussion in Discord with @mkalinin it was raised that it was not the intention of the engine API to have CLs validate the `latest_valid_hash` (LVH) and all ancestors.

Whilst I believe the engine API is being updated such that the LVH *must* identify a valid hash or be set to some junk value, I'm not confident that we can rely upon the LVH as being valid (at least for now) due to the confusion surrounding it.

Being able to validate blocks via the LVH is a relatively minor optimisation; if the LVH value ends up becoming our head we'll send an fcU and get the VALID status there.

Falsely marking a block as valid has serious consequences and since it's a minor optimisation to use LVH I think that we don't take the risk.

For clarity, we will still *invalidate* the *descendants* of the LVH, we just wont *validate* the *ancestors*.

7a6e6928a3 Further remove EE redundancy (#3324)
## Issue Addressed

Resolves #3176

## Proposed Changes

Continues from PRs by @divagant-martian to gradually remove EL redundancy (see #3284, #3257).

This PR achieves:

- Removes the `broadcast` and `first_success` methods. The functional impact is that every request to the EE will always be tried immediately, regardless of the cached `EngineState` (this resolves #3176). Previously we would check the engine state before issuing requests, this doesn't make sense in a single-EE world; there's only one EE so we might as well try it for every request.
- Runs the upcheck/watchdog routine once per slot rather than thrice. When we had multiple EEs frequent polling was useful to try and detect when the primary EE had come back online and we could switch to it. That's not as relevant now.
- Always creates logs in the `Engines::upcheck` function. Previously we would mute some logs since they could get really noisy when one EE was down but others were functioning fine. Now we only have one EE and are upcheck-ing it less, it makes sense to always produce logs.

This PR purposefully does not achieve:

- Updating all occurances of "engines" to "engine". I'm trying to keep the diff small and manageable. We can come back for this.

4212f22ddb add sync committee contribution timeout (#3291)
## Issue Addressed

Resolves #3276. 

## Proposed Changes

Add a timeout for the sync committee contributions at 1/4 the slot length such that we may be able to try backup beacon nodes in the case of contribution post failure.

## Additional Info

1/4 slot length seemed standard for the timeouts, but may want to decrease this to 1/2.

I did not find any timeout related / sync committee related tests, so there are no tests. Happy to write some with a bit of guidance.

d5e2d98970 Implement feerecipient API for keymanager (#3213)
## Issue Addressed

* #3173 

## Proposed Changes

Moved all `fee_recipient_file` related logic inside the `ValidatorStore` as it makes more sense to have this all together there. I tested this with the validators I have on `mainnet-shadow-fork-5` and everything appeared to work well. Only technicality is that I can't get the method to return `401` when the authorization header is not specified (it returns `400` instead). Fixing this is probably quite difficult given that none of `warp`'s rejections have code `401`.. I don't really think this matters too much though as long as it fails.

748475be1d Ensure caches are built for block_rewards POST API (#3305)
## Issue Addressed

Follow up to https://github.com/sigp/lighthouse/pull/3290 that fixes a caching bug

## Proposed Changes

Build the committee cache for the new `POST /lighthouse/analysis/block_rewards` API. Due to an unusual quirk of the total active balance cache the API endpoint would sometimes fail after loading a state from disk which had a current epoch cache _but not_  a total active balance cache. This PR adds calls to build the caches immediately before they're required, and has been running smoothly with `blockdreamer` the last few days.

61ed5f0ec6 Optimize historic committee calculation for the HTTP API (#3272)
## Issue Addressed

Closes https://github.com/sigp/lighthouse/issues/3270

## Proposed Changes

Optimize the calculation of historic beacon committees in the HTTP API.

This is achieved by allowing committee caches to be constructed for historic epochs, and constructing these committee caches on the fly in the API. This is much faster than reconstructing the state at the requested epoch, which usually takes upwards of 20s, and sometimes minutes with SPRP=8192. The depth of the `randao_mixes` array allows us to look back 64K epochs/0.8 years from a single state, which is pretty awesome!

We always use the `state_id` provided by the caller, but will return a nice 400 error if the epoch requested is out of range for the state requested, e.g.

```bash
# Prater
curl "http://localhost:5052/eth/v1/beacon/states/3170304/committees?epoch=33538"
```

```json
{"code":400,"message":"BAD_REQUEST: epoch out of bounds, try state at slot 1081344","stacktraces":[]}
```

Queries will be fastest when aligned to `slot % SPRP == 0`, so the hint suggests a slot that is 0 mod 8192.

66bb5c716c Use latest tags for nethermind and geth in the execution engine integration test (#3303)
## Issue Addressed

Currently the execution-engine-integration test uses latest master for nethermind and geth, and right now the test fails using the latest unreleased commits.

## Proposed Changes
Fix the nethermind and geth revisions the test uses to the latest tag in each repo. This way we are not continuously testing unreleased code, which might even get reverted, and reduce the failures only to releases in each one.
Also improve error handling of the commands used to manage the git repos.

be4e261e74 Use async code when interacting with EL (#3244)
## Overview

This rather extensive PR achieves two primary goals:

1. Uses the finalized/justified checkpoints of fork choice (FC), rather than that of the head state.
2. Refactors fork choice, block production and block processing to `async` functions.

Additionally, it achieves:

- Concurrent forkchoice updates to the EL and cache pruning after a new head is selected.
- Concurrent "block packing" (attestations, etc) and execution payload retrieval during block production.
- Concurrent per-block-processing and execution payload verification during block processing.
- The `Arc`-ification of `SignedBeaconBlock` during block processing (it's never mutated, so why not?):
    - I had to do this to deal with sending blocks into spawned tasks.
    - Previously we were cloning the beacon block at least 2 times during each block processing, these clones are either removed or turned into cheaper `Arc` clones.
    - We were also `Box`-ing and un-`Box`-ing beacon blocks as they moved throughout the networking crate. This is not a big deal, but it's nice to avoid shifting things between the stack and heap.
    - Avoids cloning *all the blocks* in *every chain segment* during sync.
    - It also has the potential to clean up our code where we need to pass an *owned* block around so we can send it back in the case of an error (I didn't do much of this, my PR is already big enough 😅)
- The `BeaconChain::HeadSafetyStatus` struct was removed. It was an old relic from prior merge specs.

For motivation for this change, see https://github.com/sigp/lighthouse/pull/3244#issuecomment-1160963273

## Changes to `canonical_head` and `fork_choice`

Previously, the `BeaconChain` had two separate fields:

```
canonical_head: RwLock<Snapshot>,
fork_choice: RwLock<BeaconForkChoice>
```

Now, we have grouped these values under a single struct:

```
canonical_head: CanonicalHead {
  cached_head: RwLock<Arc<Snapshot>>,
  fork_choice: RwLock<BeaconForkChoice>
} 
```

Apart from ergonomics, the only *actual* change here is wrapping the canonical head snapshot in an `Arc`. This means that we no longer need to hold the `cached_head` (`canonical_head`, in old terms) lock when we want to pull some values from it. This was done to avoid deadlock risks by preventing functions from acquiring (and holding) the `cached_head` and `fork_choice` locks simultaneously.

## Breaking Changes

### The `state` (root) field in the `finalized_checkpoint` SSE event

Consider the scenario where epoch `n` is just finalized, but `start_slot(n)` is skipped. There are two state roots we might in the `finalized_checkpoint` SSE event:

1. The state root of the finalized block, which is `get_block(finalized_checkpoint.root).state_root`.
4. The state root at slot of `start_slot(n)`, which would be the state from (1), but "skipped forward" through any skip slots.

Previously, Lighthouse would choose (2). However, we can see that when [Teku generates that event](de2b2801c8/data/beaconrestapi/src/main/java/tech/pegasys/teku/beaconrestapi/handlers/v1/events/EventSubscriptionManager.java (L171-L182)) it uses [`getStateRootFromBlockRoot`](de2b2801c8/data/provider/src/main/java/tech/pegasys/teku/api/ChainDataProvider.java (L336-L341)) which uses (1).

I have switched Lighthouse from (2) to (1). I think it's a somewhat arbitrary choice between the two, where (1) is easier to compute and is consistent with Teku.

## Notes for Reviewers

I've renamed `BeaconChain::fork_choice` to `BeaconChain::recompute_head`. Doing this helped ensure I broke all previous uses of fork choice and I also find it more descriptive. It describes an action and can't be confused with trying to get a reference to the `ForkChoice` struct.

I've changed the ordering of SSE events when a block is received. It used to be `[block, finalized, head]` and now it's `[block, head, finalized]`. It was easier this way and I don't think we were making any promises about SSE event ordering so it's not "breaking".

I've made it so fork choice will run when it's first constructed. I did this because I wanted to have a cached version of the last call to `get_head`. Ensuring `get_head` has been run *at least once* means that the cached values doesn't need to wrapped in an `Option`. This was fairly simple, it just involved passing a `slot` to the constructor so it knows *when* it's being run. When loading a fork choice from the store and a slot clock isn't handy I've just used the `slot` that was saved in the `fork_choice_store`. That seems like it would be a faithful representation of the slot when we saved it.

I added the `genesis_time: u64` to the `BeaconChain`. It's small, constant and nice to have around.

Since we're using FC for the fin/just checkpoints, we no longer get the `0x00..00` roots at genesis. You can see I had to remove a work-around in `ef-tests` here: b56be3bc2. I can't find any reason why this would be an issue, if anything I think it'll be better since the genesis-alias has caught us out a few times (0x00..00 isn't actually a real root). Edit: I did find a case where the `network` expected the 0x00..00 alias and patched it here: 3f26ac3e2.

You'll notice a lot of changes in tests. Generally, tests should be functionally equivalent. Here are the things creating the most diff-noise in tests:
- Changing tests to be `tokio::async` tests.
- Adding `.await` to fork choice, block processing and block production functions.
- Refactor of the `canonical_head` "API" provided by the `BeaconChain`. E.g., `chain.canonical_head.cached_head()` instead of `chain.canonical_head.read()`.
- Wrapping `SignedBeaconBlock` in an `Arc`.
- In the `beacon_chain/tests/block_verification`, we can't use the `lazy_static` `CHAIN_SEGMENT` variable anymore since it's generated with an async function. We just generate it in each test, not so efficient but hopefully insignificant.

I had to disable `rayon` concurrent tests in the `fork_choice` tests. This is because the use of `rayon` and `block_on` was causing a panic.

a7da0677d5 Remove builder redundancy (#3294)
## Issue Addressed

This PR is a subset of the changes in #3134. Unstable will still not function correctly with the new builder spec once this is merged, #3134 should be used on testnets

## Proposed Changes

- Removes redundancy in "builders" (servers implementing the builder spec)
- Renames `payload-builder` flag to `builder`
- Moves from old builder RPC API to new HTTP API, but does not implement the validator registration API (implemented in https://github.com/sigp/lighthouse/pull/3194)

f6ec44f0dd Register validator api (#3194)
## Issue Addressed

Lays the groundwork for builder API changes by implementing the beacon-API's new `register_validator` endpoint

## Proposed Changes

- Add a routine in the VC that runs on startup (re-try until success), once per epoch or whenever `suggested_fee_recipient` is updated, signing `ValidatorRegistrationData` and sending it to the BN.
  -  TODO: `gas_limit` config options https://github.com/ethereum/builder-specs/issues/17
-  BN only sends VC registration data to builders on demand, but VC registration data *does update* the BN's prepare proposer cache and send an updated fcU to  a local EE. This is necessary for fee recipient consistency between the blinded and full block flow in the event of fallback.  Having the BN only send registration data to builders on demand gives feedback directly to the VC about relay status. Also, since the BN has no ability to sign these messages anyways (so couldn't refresh them if it wanted), and validator registration is independent of the BN head, I think this approach makes sense. 
- Adds upcoming consensus spec changes for this PR https://github.com/ethereum/consensus-specs/pull/2884
  -  I initially applied the bit mask based on a configured application domain.. but I ended up just hard coding it here instead because that's how it's spec'd in the builder repo. 
  -  Should application mask appear in the api?

5de00b7ee8 Unify execution layer endpoints (#3214)
## Issue Addressed

Resolves #3069 

## Proposed Changes

Unify the `eth1-endpoints` and `execution-endpoints` flags in a backwards compatible way as described in https://github.com/sigp/lighthouse/issues/3069#issuecomment-1134219221

Users have 2 options:
1. Use multiple non auth execution endpoints for deposit processing pre-merge
2. Use a single jwt authenticated execution endpoint for both execution layer and deposit processing post merge

Related https://github.com/sigp/lighthouse/issues/3118

To enable jwt authenticated deposit processing, this PR removes the calls to `net_version` as the `net` namespace is not exposed in the auth server in execution clients. 
Moving away from using `networkId` is a good step in my opinion as it doesn't provide us with any added guarantees over `chainId`. See https://github.com/ethereum/consensus-specs/issues/2163 and https://github.com/sigp/lighthouse/issues/2115

53b2b500db Extend block reward APIs (#3290)
## Proposed Changes

Add a new HTTP endpoint `POST /lighthouse/analysis/block_rewards` which takes a vec of `BeaconBlock`s as input and outputs the `BlockReward`s for them.

Augment the `BlockReward` struct with the attestation data for attestations in the block, which simplifies access to this information from blockprint. Using attestation data I've been able to make blockprint up to 95% accurate across Prysm/Lighthouse/Teku/Nimbus. I hope to go even higher using a bunch of synthetic blocks produced for Prysm/Nimbus/Lodestar, which are underrepresented in the current training data.

## Proposed Changes

Update `Cross.toml` for the recently released Cross v0.2.2. This allows us to remove the dependency on my fork of the Cross Docker image, which was a maintenance burden and prone to bit-rot. This PR puts us back in sync with upstream Cross.

## Additional Info

Due to some bindgen errors on the default Cross images we seemingly need a full `clang-3.9` install. The `libclang-3.9-dev` package was found to be insufficient due to `stdarg.h` being missing.

In order to continue building locally all Lighthouse devs should update their local cross version with `cargo install cross`.

Allows the deposit caching to recover from `NonConsecutive` deposit errors by resetting the last processed block to the last valid deposit's block number. Still not sure of the underlying cause of this error, but this should recover the cache so we don't need `--eth1-purge-cache` anymore 🎉 

A huge thanks to @one-three-three-seven for reproducing the error and providing the data that helped testing out the fix 🙌

## Issue Addressed

Part of #3160 

## Proposed Changes
Use only the first url given in the execution engine, if more than one is provided log it.
This change only moves having multiple engines to one. The amount of code cleanup that can and should be done forward is not small and would interfere with ongoing PRs. I'm keeping the changes intentionally very very minimal.

## Additional Info

Future works:
- In [ `EngineError` ](9c429d0764/beacon_node/execution_layer/src/engines.rs (L173-L177)) the id is not needed since it now has no meaning.
- the [ `first_success_without_retry` ](9c429d0764/beacon_node/execution_layer/src/engines.rs (L348-L351)) function can return a single error.
- the [`first_success`](9c429d0764/beacon_node/execution_layer/src/engines.rs (L324)) function can return a single error.
- After the redundancy is removed for the builders, we can probably make the [ `EngineErrors` ](9c429d0764/beacon_node/execution_layer/src/lib.rs (L69)) carry a single error.
- Merge the [`Engines`](9c429d0764/beacon_node/execution_layer/src/engines.rs (L161-L165)) struct and [`Engine` ](9c429d0764/beacon_node/execution_layer/src/engines.rs (L62-L67))
- Fix the associated configurations and cli params. Not sure if both are done in https://github.com/sigp/lighthouse/pull/3214

In general I think those changes can be done incrementally and in individual pull requests.

8faaa35b58 Enable malloc metrics for the VC (#3279)
## Issue Addressed

Following up from https://github.com/sigp/lighthouse/pull/3223#issuecomment-1158718102, it has been observed that the validator client uses vastly more memory in some compilation configurations than others. Compiling with Cross and then putting the binary into an Ubuntu 22.04 image seems to use 3x more memory than compiling with Cargo directly on Debian bullseye.

## Proposed Changes

Enable malloc metrics for the validator client. This will hopefully allow us to see the difference between the two compilation configs and compare heap fragmentation. This PR doesn't enable malloc tuning for the VC because it was found to perform significantly worse. The `--disable-malloc-tuning` flag is repurposed to just disable the metrics.

efebf712dd Avoid cloning snapshots during sync (#3271)
## Issue Addressed

Closes https://github.com/sigp/lighthouse/issues/2944

## Proposed Changes

Remove snapshots from the cache during sync rather than cloning them. This reduces unnecessary cloning and memory fragmentation during sync.

## Additional Info

This PR relies on the fact that the `block_delay` cache is not populated for blocks from sync. Relying on block delay may have the side effect that a change in `block_delay` calculation could lead to: a) more clones, if block delays are added for syncing blocks or b) less clones, if blocks near the head are erroneously provided without a `block_delay`. Case (a) would be a regression to the current status quo, and (b) is low-risk given we know that the snapshot cache is current susceptible to misses (hence `tree-states`).

a9e158663b Fix validator_monitor_prev_epoch_ metrics (#2911)
## Issue Addressed

#2820

## Proposed Changes

The problem is that validator_monitor_prev_epoch metrics are updated only if there is EpochSummary present in summaries map for the previous epoch and it is not the case for the offline validator. Ensure that EpochSummary is inserted into summaries map also for the offline validators.

f428719761 Do not penalize peers on execution layer offline errors (#3258)
## Issue Addressed

Partly resolves https://github.com/sigp/lighthouse/issues/3032

## Proposed Changes

Extracts some of the functionality of #3094 into a separate PR as the original PR requires a bit more work.
Do not unnecessarily penalize peers when we fail to validate received execution payloads because our execution layer is offline.

11d80a6a38 Optimise per_epoch_processing low-hanging-fruit (#3254)
## Issue Addressed

NA

## Proposed Changes

- Uses a `Vec` in `SingleEpochParticipationCache` rather than `HashMap` to speed up processing times at the cost of memory usage.
- Cache the result of `integer_sqrt` rather than recomputing for each validator.
- Cache `state.previous_epoch` rather than recomputing it for each validator.

1d016a83f2 Lint against panicky calls in async functions (#3250)
## Description

Add a new lint to CI that attempts to detect calls to functions like `block_on` from async execution contexts. This lint was written from scratch exactly for this purpose, on my fork of Clippy: https://github.com/michaelsproul/rust-clippy/tree/disallow-from-async

## Additional Info

- I've successfully detected the previous two issues we had with `block_on` by running the linter on the commits prior to each of these PRs: https://github.com/sigp/lighthouse/pull/3165, https://github.com/sigp/lighthouse/pull/3199.
- The lint runs on CI with `continue-on-error: true` so that if it fails spuriously it won't block CI.
- I think it would be good to merge this PR before https://github.com/sigp/lighthouse/pull/3244 so that we can lint the extensive executor-related changes in that PR.
- I aim to upstream the lint to Clippy, at which point building a custom version of Clippy from my fork will no longer be necessary. I imagine this will take several weeks or months though, because the code is currently a bit hacky and will need some renovations to pass review.

452b46a7af Pin MDBX at last version with Win/Mac support (#3246)
## Issue Addressed

Newer versions of MDBX have removed Windows and macOS support, so this PR pins MDBX at the last working version to prevent an accidental regression via `cargo update`.

## Additional Info

This is a short-term solution, if our pinned version of MDBX turns out to be buggy we will need to consider backporting patches from upstream to our own fork.

9c429d0764 Only use authenticated endpoints during EE integration testing (#3253)
## Issue Addressed

Failures in our CI integration tests for Geth.

## Proposed Changes

Only connect to the authenticated execution endpoints during execution tests.
This is necessary now that it is impossible to connect to the `engine` api on an unauthenticated endpoint.
See https://github.com/ethereum/go-ethereum/pull/24997

## Additional Info

As these tests break semi-regularly, I have kept logs enabled to ease future debugging.
I've also updated the Nethermind tests, although these weren't broken. This should future-proof us if Nethermind decides to follow suit with Geth

cfd26d25e0 do not count sync batch attempts when peer is not at fault (#3245)
## Issue Addressed
currently we count a failed attempt for a syncing chain even if the peer is not at fault. This makes us do more work if the chain fails, and heavily penalize peers, when we can simply retry. Inspired by a proposal I made to #3094 

## Proposed Changes
If a batch fails but the peer is not at fault, do not count the attempt
Also removes some annoying logs

## Additional Info
We still get a counter on ignored attempts.. just in case

54cf94ea59 Fix per-slot timer in presence of clock changes (#3243)
## Issue Addressed

Fixes a timing issue that results in spurious fork choice notifier failures:

```
WARN Error signalling fork choice waiter     slot: 3962270, error: ForkChoiceSignalOutOfOrder { current: Slot(3962271), latest: Slot(3962270) }, service: beacon
```

There’s a fork choice run that is scheduled to run at the start of every slot by the `timer`, which creates a 12s interval timer when the beacon node starts up. The problem is that if there’s a bit of clock drift that gets corrected via NTP (or a leap second for that matter) then these 12s intervals will cease to line up with the start of the slot. This then creates the mismatch in slot number that we see above.

Lighthouse also runs fork choice 500ms before the slot begins, and these runs are what is conflicting with the start-of-slot runs. This means that the warning in current versions of Lighthouse is mostly cosmetic because fork choice is up to date with all but the most recent 500ms of attestations (which usually isn’t many).

## Proposed Changes

Fix the per-slot timer so that it continually re-calculates the duration to the start of the next slot and waits for that.

A side-effect of this change is that we may skip slots if the per-slot task takes >12s to run, but I think this is an unlikely scenario and an acceptable compromise.

493c2c037c reduce reprocess queue/channel sizes (#3239)
## Issue Addressed

Reduces the effect of late blocks on overall node buildup

## Proposed Changes

change the capacity of the channels used to send work for reprocessing in the beacon processor, and to send back to the main processor task, to be 75% of the capacity of the channel for receiving new events

## Additional Info

The issues we've seen suggest we should still evaluate node performance under stress, with late blocks being a big factor. 
Other changes that could help: 
1. right now we have a cap for queued attestations for reprocessing that applies to the sum of aggregated and unaggregated attestations. We could consider adding a separate cap that favors aggregated ones.
2. solving #2848

a6d2ed6119 Fix: PeerManager doesn't remove "outbound only" peers which should be pruned (#3236)
## Issue Addressed

This is one step to address https://github.com/sigp/lighthouse/issues/3092 before introducing `quickcheck`.

I noticed an issue while I was reading the pruning implementation `PeerManager::prune_excess_peers()`. If a peer with the following condition, **`outbound_peers_pruned` counter increases but the peer is not pushed to `peers_to_prune`**.

- [outbound only](1e4ac8a4b9/beacon_node/lighthouse_network/src/peer_manager/mod.rs (L1018))
- [min_subnet_count <= MIN_SYNC_COMMITTEE_PEERS](1e4ac8a4b9/beacon_node/lighthouse_network/src/peer_manager/mod.rs (L1047))

As a result, PeerManager doesn't remove "outbound" peers which should be pruned.

Note: [`subnet_to_peer`](e0d673ea86/beacon_node/lighthouse_network/src/peer_manager/mod.rs (L999)) (HashMap) doesn't guarantee a particular order of iteration. So whether the test fails depend on the order of iteration.
