3a5888e53d Ban and unban peers at the swarm level (#3653)
## Issue Addressed

I missed this from https://github.com/sigp/lighthouse/pull/3491. peers were being banned at the behaviour level only. The identify errors are explained by this as well

## Proposed Changes

Add banning and unbanning 

## Additional Info

Befor,e having tests that catch this was hard because the swarm was outside the behaviour. We could now have tests that prevent something like this in the future

dbb93cd0d2 bors: require slasher and syncing sim tests (#3645)
## Issue Addressed
I noticed that [this build](https://github.com/sigp/lighthouse/actions/runs/3269950873/jobs/5378036501) wasn't marked failed by Bors when the `syncing-simulator-ubuntu` job failed. This is because that job is absent from the `bors.toml` config.

## Proposed Changes

Add missing jobs to Bors config so that they are required:

- `syncing-simulator-ubuntu`
- `slasher-tests`
- `disallowed-from-async-lint`

The `disallowed-from-async-lint` was previously allowed to fail because it was considered beta, but I think it's stable enough now we may as well require it.

edf23bb40e Fix attestation shuffling filter (#3629)
## Issue Addressed

Fix a bug in block production that results in blocks with 0 attestations during the first slot of an epoch.

The bug is marked by debug logs of the form:

> DEBG Discarding attestation because of missing ancestor, block_root: 0x3cc00d9c9e0883b2d0db8606278f2b8423d4902f9a1ee619258b5b60590e64f8, pivot_slot: 4042591

It occurs when trying to look up the shuffling decision root for an attestation from a slot which is prior to fork choice's finalized block. This happens frequently when proposing in the first slot of the epoch where we have:

- `current_epoch == n`
- `attestation.data.target.epoch == n - 1`
- attestation shuffling epoch `== n - 3` (decision block being the last block of `n - 3`)
- `state.finalized_checkpoint.epoch == n - 2` (first block of `n - 2` is finalized)

Hence the shuffling decision slot is out of range of the fork choice backwards iterator _by a single slot_.

Unfortunately this bug was hidden when we weren't pruning fork choice, and then reintroduced in v2.5.1 when we fixed the pruning (https://github.com/sigp/lighthouse/releases/tag/v2.5.1). There's no way to turn that off or disable the filtering in our current release, so we need a new release to fix this issue.

Fortunately, it also does not occur on every epoch boundary because of the gradual pruning of fork choice every 256 blocks (~8 epochs):

01e84b71f5/consensus/proto_array/src/proto_array_fork_choice.rs (L16)

01e84b71f5/consensus/proto_array/src/proto_array.rs (L713-L716)

So the probability of proposing a 0-attestation block given a proposal assignment is approximately `1/32 * 1/8 = 0.39%`.

## Proposed Changes

- Load the block's shuffling ID from fork choice and verify it against the expected shuffling ID of the head state. This code was initially written before we had settled on a representation of shuffling IDs, so I think it's a nice simplification to make use of them here rather than more ad-hoc logic that fundamentally does the same thing.

## Additional Info

Thanks to @moshe-blox for noticing this issue and bringing it to our attention.

59ec6b71b8 Consensus context with proposer index caching (#3604)
## Issue Addressed

Closes https://github.com/sigp/lighthouse/issues/2371

## Proposed Changes

Backport some changes from `tree-states` that remove duplicated calculations of the `proposer_index`.

With this change the proposer index should be calculated only once for each block, and then plumbed through to every place it is required.

## Additional Info

In future I hope to add more data to the consensus context that is cached on a per-epoch basis, like the effective balances of validators and the base rewards.

There are some other changes to remove indexing in tests that were also useful for `tree-states` (the `tree-states` types don't implement `Index`).

e4cbdc1c77 Optimistic sync spec tests (v1.2.0) (#3564)
## Issue Addressed

Implements new optimistic sync test format from https://github.com/ethereum/consensus-specs/pull/2982.

## Proposed Changes

- Add parsing and runner support for the new test format.
- Extend the mock EL with a set of canned responses keyed by block hash. Although this doubles up on some of the existing functionality I think it's really nice to use compared to the `preloaded_responses` or static responses. I think we could write novel new opt sync tests using these primtives much more easily than the previous ones. Forks are natively supported, and different responses to `forkchoiceUpdated` and `newPayload` are also straight-forward.

## Additional Info

Blocked on merge of the spec PR and release of new test vectors.

ca9dc8e094 Optimise HTTP validator lookups (#3559)
## Issue Addressed

While digging around in some logs I noticed that queries for validators by pubkey were taking 10ms+, which seemed too long. This was due to a loop through the entire validator registry for each lookup.

## Proposed Changes

Rather than using a loop through the register, this PR utilises the pubkey cache which is usually initialised at the head*. In case the cache isn't built, we fall back to the previous loop logic. In the vast majority of cases I expect the cache will be built, as the validator client queries at the `head` where all caches should be built.

## Additional Info

*I had to modify the cache build that runs after fork choice to build the pubkey cache. I think it had been optimised out, perhaps accidentally. I think it's preferable to have the exit cache and the pubkey cache built on the head state, as they are required for verifying deposits and exits respectively, and we may as well build them off the hot path of block processing. Previously they'd get built the first time a deposit or exit needed to be verified.

I've deleted the unused `map_state` function which was obsoleted by `map_state_and_execution_optimistic`.

#2629 

## Proposed Changes

Please list or describe the changes introduced by this PR.

1. ci would dowload the bls test cases from https://github.com/ethereum/bls12-381-tests/
2. all the bls test cases(except eth ones) would use cases in the archive from step one
3. The bls test cases from https://github.com/ethereum/consensus-spec-tests would stay there and no use . For the future , these bls test cases would be remove suggested from https://github.com/ethereum/consensus-spec-tests/issues/25 . So it would do no harm and compatible for future cases.

242ae21e5d Pass EL JWT secret key via cli flag (#3568)
## Proposed Changes

In this change I've added a new beacon_node cli flag `--execution-jwt-secret-key` for passing the JWT secret directly as string.

Without this flag, it was non-trivial to pass a secrets file containing a JWT secret key without compromising its contents into some management repo or fiddling around with manual file mounts for cloud-based deployments.

When used in combination with environment variables, the secret can be injected into container-based systems like docker & friends quite easily.

It's both possible to either specify the file_path to the JWT secret or pass the JWT secret directly.

I've modified the docs and attached a test as well.

## Additional Info

The logic has been adapted a bit so that either one of `--execution-jwt` or `--execution-jwt-secret-key` must be set when specifying `--execution-endpoint` so that it's still compatible with the semantics before this change and there's at least one secret provided.

8728c40102 Remove fallback support from eth1 service (#3594)
## Issue Addressed

N/A

## Proposed Changes

With https://github.com/sigp/lighthouse/pull/3214 we made it such that you can either have 1 auth endpoint or multiple non auth endpoints. Now that we are post merge on all networks (testnets and mainnet), we cannot progress a chain without a dedicated auth execution layer connection so there is no point in having a non-auth eth1-endpoint for syncing deposit cache. 

This code removes all fallback related code in the eth1 service. We still keep the single non-auth endpoint since it's useful for testing.

## Additional Info

This removes all eth1 fallback related metrics that were relevant for the monitoring service, so we might need to change the api upstream.

58bd2f76d0 Ensure protoc is installed for release CI (#3621)
## Issue Addressed

The release CI is currently broken due to the addition of the `protoc` dependency. Here's a failure of the release flow running on my fork: https://github.com/michaelsproul/lighthouse/actions/runs/3155541478/jobs/5134317334

## Proposed Changes

- Install `protoc` on Windows and Mac so that it's available for `cargo install`.
- Install an x86_64 binary in the Cross image for the aarch64 platform: we need a binary that runs on the host, _not_ on the target.
- Fix `macos` local testnet CI by using the Github API key to dodge rate limiting (this issue: https://github.com/actions/runner-images/issues/602).

f77e3bc0ad Add maxperf build profile (#3608)
## Proposed Changes

Add a new Cargo compilation profile called `maxperf` which enables more aggressive compiler optimisations at the expense of compilation time.

Some rough initial benchmarks show that this can provide up to a 25% reduction to run time for CPU bound tasks like block processing: https://docs.google.com/spreadsheets/d/15jHuZe7lLHhZq9Nw8kc6EL0Qh_N_YAYqkW2NQ_Afmtk/edit

The numbers in that spreadsheet compare the `consensus-context` branch from #3604 to the same branch compiled with the `maxperf` profile using:

```
PROFILE=maxperf make install-lcli
```

## Additional Info

The downsides of the maxperf profile are:

- It increases compile times substantially, which will particularly impact low-spec hardware. Compiling `lcli` is about 3x slower. Compiling Lighthouse is about 5x slower on my 5950X: 17m 38s rather than 3m 28s.

As a result I think we should not enable this everywhere by default.

- **Option 1**: enable by default for our released binaries. This gives the majority of users the fastest version of `lighthouse` possible, at the expense of slowing down our release CI. Source builds will continue to use the default `release` profile unless users opt-in to `maxperf`.
- **Option 2**: enable by default for source builds. This gives users building from source an edge, but makes them pay for it with compilation time. 

I think I would prefer Option 1. I'll try doing some benchmarking to see how long a maxperf build of Lighthouse would take on GitHub actions.

9bd384a573 send attnet unsubscription event on random subnet expiry (#3600)
## Issue Addressed
🐞 in which we don't actually unsubscribe from a random long lived subnet when it expires

## Proposed Changes

Remove code addressing a specific case in which we are subscribed to all subnets and handle the removal of the long lived subnet. I don't think the special case code is particularly important as, if someone is running with that many validators to be subscribed to all subnets, it should use `--subscribe-all-subnets` instead

## Additional Info

NA

## Proposed Changes

This PR attempts to fix the following spurious CI failure:

fa6ad1a11a Deduplicate block root computation (#3590)
## Issue Addressed

NA

## Proposed Changes

This PR removes duplicated block root computation.

Computing the `SignedBeaconBlock::canonical_root` has become more expensive since the merge as we need to compute the merke root of each transaction inside an `ExecutionPayload`.

Computing the root for [a mainnet block](https://beaconcha.in/slot/4704236) is taking ~10ms on my i7-8700K CPU @ 3.70GHz (no sha extensions). Given that our median seen-to-imported time for blocks is presently 300-400ms, removing a few duplicated block roots (~30ms) could represent an easy 10% improvement. When we consider that the seen-to-imported times include operations *after* the block has been placed in the early attester cache, we could expect the 30ms to be more significant WRT our seen-to-attestable times.

507bb9dad4 Refined payload pruning (#3587)
## Proposed Changes

Improve the payload pruning feature in several ways:

- Payload pruning is now entirely optional. It is enabled by default but can be disabled with `--prune-payloads false`. The previous `--prune-payloads-on-startup` flag from #3565 is removed.
- Initial payload pruning on startup now runs in a background thread. This thread will always load the split state, which is a small fraction of its total work (up to ~300ms) and then backtrack from that state. This pruning process ran in 2m5s on one Prater node with good I/O and 16m on a node with slower I/O.
- To work with the optional payload pruning the database function `try_load_full_block` will now attempt to load execution payloads for finalized slots _if_ pruning is currently disabled. This gives users an opt-out for the extensive traffic between the CL and EL for reconstructing payloads.

## Additional Info

If the `prune-payloads` flag is toggled on and off then the on-startup check may not see any payloads to delete and fail to clean them up. In this case the `lighthouse db prune_payloads` command should be used to force a manual sweep of the database.

f2ac0738d8 Implement skip_randao_verification and blinded block rewards API (#3540)
## Issue Addressed

https://github.com/ethereum/beacon-APIs/pull/222

## Proposed Changes

Update Lighthouse's randao verification API to match the `beacon-APIs` spec. We implemented the API before spec stabilisation, and it changed slightly in the course of review.

Rather than a flag `verify_randao` taking a boolean value, the new API uses a `skip_randao_verification` flag which takes no argument. The new spec also requires the randao reveal to be present and equal to the point-at-infinity when `skip_randao_verification` is set.

I've also updated the `POST /lighthouse/analysis/block_rewards` API to take blinded blocks as input, as the execution payload is irrelevant and we may want to assess blocks produced by builders.

## Additional Info

This is technically a breaking change, but seeing as I suspect I'm the only one using these parameters/APIs, I think we're OK to include this in a patch release.

ca42ef2e5a Prune finalized execution payloads (#3565)
## Issue Addressed

Closes https://github.com/sigp/lighthouse/issues/3556

## Proposed Changes

Delete finalized execution payloads from the database in two places:

1. When running the finalization migration in `migrate_database`. We delete the finalized payloads between the last split point and the new updated split point. _If_ payloads are already pruned prior to this then this is sufficient to prune _all_ payloads as non-canonical payloads are already deleted by the head pruner, and all canonical payloads prior to the previous split will already have been pruned.
2. To address the fact that users will update to this code _after_ the merge on mainnet (and testnets), we need a one-off scan to delete the finalized payloads from the canonical chain. This is implemented in `try_prune_execution_payloads` which runs on startup and scans the chain back to the Bellatrix fork or the anchor slot (if checkpoint synced after Bellatrix). In the case where payloads are already pruned this check only imposes a single state load for the split state, which shouldn't be _too slow_. Even so, a flag `--prepare-payloads-on-startup=false` is provided to turn this off after it has run the first time, which provides faster start-up times.

There is also a new `lighthouse db prune_payloads` subcommand for users who prefer to run the pruning manually.

## Additional Info

The tests have been updated to not rely on finalized payloads in the database, instead using the `MockExecutionLayer` to reconstruct them. Additionally a check was added to `check_chain_dump` which asserts the non-existence or existence of payloads on disk depending on their slot.

Fixes a potential regression in memory fragmentation identified by @paulhauner here: https://github.com/sigp/lighthouse/pull/3371#discussion_r931770045.

## Proposed Changes

Immediately allocate a vector with sufficient size to hold all decoded elements in SSZ decoding. The `size_hint` is derived from the range iterator here:

2983235650/consensus/ssz/src/decode/impls.rs (L489)

## Additional Info

I'd like to test this out on some infra for a substantial duration to see if it affects total fragmentation.

b0b606dabe Use SmallVec for TreeHash packed encoding (#3581)
## Issue Addressed

NA

## Proposed Changes

I've noticed that our block hashing times increase significantly after the merge. I did some flamegraph-ing and noticed that we're allocating a `Vec` for each byte of each execution payload transaction. This seems like unnecessary work and a bit of a fragmentation risk.

This PR switches to `SmallVec<[u8; 32]>` for the packed encoding of `TreeHash`. I believe this is a nice simple optimisation with no downside.

### Benchmarking

These numbers were computed using #3580 on my desktop (i7 hex-core). You can see a bit of noise in the numbers, that's probably just my computer doing other things. Generally I found this change takes the time from 10-11ms to 8-9ms. I can also see all the allocations disappear from flamegraph.

This is the block being benchmarked: https://beaconcha.in/slot/4704236

2cd3e3a768 Avoid duplicate committee cache loads (#3574)
## Issue Addressed

NA

## Proposed Changes

I have observed scenarios on Goerli where Lighthouse was receiving attestations which reference the same, un-cached shuffling on multiple threads at the same time. Lighthouse was then loading the same state from database and determining the shuffling on multiple threads at the same time. This is unnecessary load on the disk and RAM.

This PR modifies the shuffling cache so that each entry can be either:

- A committee
- A promise for a committee (i.e., a `crossbeam_channel::Receiver`)

Now, in the scenario where we have thread A and thread B simultaneously requesting the same un-cached shuffling, we will have the following:

1. Thread A will take the write-lock on the shuffling cache, find that there's no cached committee and then create a "promise" (a `crossbeam_channel::Sender`) for a committee before dropping the write-lock.
1. Thread B will then be allowed to take the write-lock for the shuffling cache and find the promise created by thread A. It will block the current thread waiting for thread A to fulfill that promise.
1. Thread A will load the state from disk, obtain the shuffling, send it down the channel, insert the entry into the cache and then continue to verify the attestation.
1. Thread B will then receive the shuffling from the receiver, be un-blocked and then continue to verify the attestation.

In the case where thread A fails to generate the shuffling and drops the sender, the next time that specific shuffling is requested we will detect that the channel is disconnected and return a `None` entry for that shuffling. This will cause the shuffling to be re-calculated.
