## Proposed Changes
Disallow the production of attestations and retrieval of unaggregated attestations when they reference an optimistic head. Add tests to this end.
I also moved `BeaconChain::produce_unaggregated_attestation_for_block` to the `BeaconChainHarness`. It was only being used during tests, so it's nice to stop pretending it's production code. I also needed something that could produce attestations to optimistic blocks in order to simulate scenarios where the justified checkpoint is determined invalid (if no one would attest to an optimistic block, we could never justify it and then flip it to invalid).

## Issue Addressed
In very rare occasions we've seen most if not all our peers in a chain with which we don't agree. Purging these peers can take a very long time: number of retries of the chain. Meanwhile sync is caught in a loop trying the chain again and again. This makes it so that we fast track purging peers via registering the failed chain to prevent retrying for some time (30 seconds). Longer times could be dangerous since a chain can fail if a batch fails to download for example. In this case, I think it's still acceptable to fast track purging peers since they are nor providing the required info anyway

## Proposed Changes
https://github.com/sigp/lighthouse/pull/3133 changed the rpc type limits to be fork aware i.e. if our current fork based on wall clock slot is Altair, then we apply only altair rpc type limits. This is a bug because phase0 blocks can still be sent over rpc and phase 0 block minimum size is smaller than altair block minimum size. So a phase0 block with `size < SIGNED_BEACON_BLOCK_ALTAIR_MIN` will return an `InvalidData` error as it doesn't pass the rpc types bound check.
This error can be seen when we try syncing pre-altair blocks with size smaller than `SIGNED_BEACON_BLOCK_ALTAIR_MIN`.
This PR fixes the issue by also accounting for forks earlier than current_fork in the rpc limits calculation in the `rpc_block_limits_by_fork` function. I decided to hardcode the limits in the function because that seemed simpler than calculating previous forks based on current fork and doing a min across forks. Adding a new fork variant is simple and can the limits can be easily checked in a review.
Adds unit tests and modifies the syncing simulator to check the syncing from across fork boundaries.
The syncing simulator's block 1 would always be of phase 0 minimum size (404 bytes) which is smaller than altair min block size (since block 1 contains no attestations).

## Proposed Changes
Cut release v2.2.0 including proposer boost.
## Additional Info
I also updated the clippy lints for the imminent release of Rust 1.60, although LH v2.2.0 will continue to compile using Rust 1.58 (our MSRV).
## Proposed Changes
I did some gardening 🌳 in our dependency tree:
- Remove duplicate versions of `warp` (git vs patch)
- Remove duplicate versions of lots of small deps: `cpufeatures`, `ethabi`, `ethereum-types`, `bitvec`, `nix`, `libsecp256k1`.
- Update MDBX (should resolve#3028). I tested and Lighthouse compiles on Windows 11 now.
- Restore `psutil` back to upstream
- Make some progress updating everything to rand 0.8. There are a few crates stuck on 0.7.
Hopefully this puts us on a better footing for future `cargo audit` issues, and improves compile times slightly.
## Additional Info
Some crates are held back by issues with `zeroize`. libp2p-noise depends on [`chacha20poly1305`](https://crates.io/crates/chacha20poly1305) which depends on zeroize < v1.5, and we can only have one version of zeroize because it's post 1.0 (see https://github.com/rust-lang/cargo/issues/6584). The latest version of `zeroize` is v1.5.4, which is used by the new versions of many other crates (e.g. `num-bigint-dig`). Once a new version of chacha20poly1305 is released we can update libp2p-noise and upgrade everything to the latest `zeroize` version.
I've also opened a PR to `blst` related to zeroize: https://github.com/supranational/blst/pull/111

Fix the upper bound for blocks by root responses to be equal to the max merge block size instead of altair.
Further make the rpc response limits fork aware.
## Proposed Changes
Increase the default `--slots-per-restore-point` to 8192 for a 4x reduction in freezer DB disk usage.
Existing nodes that use the previous default of 2048 will be left unchanged. Newly synced nodes (with or without checkpoint sync) will use the new 8192 default.
Long-term we could do away with the freezer DB entirely for validator-only nodes, but this change is much simpler and grants us some extra space in the short term. We can also roll it out gradually across our nodes by purging databases one by one, while keeping the Ansible config the same.
## Additional Info
We ignore a change from 2048 to 8192 if the user hasn't set the 8192 explicitly. We fire a debug log in the case where we do ignore:
```
DEBG Ignoring slots-per-restore-point config in favour of on-disk value, on_disk: 2048, config: 8192
```
## Proposed Changes
Add a `lighthouse db` command with three initial subcommands:
- `lighthouse db version`: print the database schema version.
- `lighthouse db migrate --to N`: manually upgrade (or downgrade!) the database to a different version.
- `lighthouse db inspect --column C`: log the key and size in bytes of every value in a given `DBColumn`.
This PR lays the groundwork for other changes, namely:
- Mark's fast-deposit sync (https://github.com/sigp/lighthouse/pull/2915), for which I think we should implement a database downgrade (from v9 to v8).
- My `tree-states` work, which already implements a downgrade (v10 to v8).
- Standalone purge commands like `lighthouse db purge-dht` per https://github.com/sigp/lighthouse/issues/2824.
## Additional Info
I updated the `strum` crate to 0.24.0, which necessitated some changes in the network code to remove calls to deprecated methods.
Thanks to @winksaville for the motivation, and implementation work that I used as a source of inspiration (https://github.com/sigp/lighthouse/pull/2685).

- Update the JSON-RPC id field for both our request and response objects to be a `serde_json::Value` rather than a `u32`. This field could be a string or a number according to the JSON-RPC 2.0 spec. We only ever set it to a number, but if, for example, we get a response that wraps this number in quotes, we would fail to deserialize it. I think because we're not doing any validation around this id otherwise, we should be less strict with it in this regard.

## Proposed Changes
In the first Goerli shadow-fork, Lighthouse was getting timeouts from Geth which prevented the LH+Geth pair from progressing.
There's not a whole lot of information I can use to set these timeouts. The most interesting pieces of information I have are quotes from Marius from Geth:
- *"Fcu also needs to construct the block which can take 2sec"* ([Discord](https://discord.com/channels/595666850260713488/910910348922589184/958006487052066836))
- *"2 sec should be ok for new payload, weird that it times out"* ([Discord](https://discord.com/channels/595666850260713488/910910348922589184/958006487052066836))
I don't think we should be so worried about getting these timeouts correct now. No one really knows how long the various EEs are going to take, it's a bit too early in development. With these changes I'm giving some headroom so that we don't fail just because EEs are quite optimized enough. I've set the value to 6s (half a mainnet slot), since I think anything beyond 6s is an interesting problem that we want to know about sooner rather than later.

## Proposed Changes
Set the engine state to `EngineState::Offline` if the engine api call fails during broadcast. This caused issues while pausing sync when the execution engine is offline because `EngineState` always returned `Synced`.
## Proposed Changes
Allow Lighthouse to speculatively create blocks via the `/eth/v1/validators/blocks` endpoint by optionally skipping the RANDAO verification that we introduced in #2740. When `verify_randao=false` is passed as a query parameter the `randao_reveal` is not required to be present, and if present will only be lightly checked (must be a valid BLS sig). If `verify_randao` is omitted it defaults to true and Lighthouse behaves exactly as it did previously, hence this PR is backwards-compatible.
I'd like to get this change into `unstable` pretty soon as I've got 3 projects building on top of it:
- [`blockdreamer`](https://github.com/michaelsproul/blockdreamer), which mocks block production every slot in order to fingerprint clients
- analysis of Lighthouse's block packing _optimality_, which uses `blockdreamer` to extract interesting instances of the attestation packing problem
- analysis of Lighthouse's block packing _performance_ (as in speed) on the `tree-states` branch
## Additional Info
Having tested `blockdreamer` with Prysm, Nimbus and Teku I noticed that none of them verify the randao signature on `/eth/v1/validator/blocks`. I plan to open a PR to the `beacon-APIs` repo anyway so that this parameter can be standardised in case the other clients add RANDAO verification by default in future.

## Issue Addressed
#3103
## Proposed Changes
Parse `http-address` and `metrics-address` as `IpAddr` for both the beacon node and validator client to support IPv6 addresses.
Also adjusts parsing of CORS origins to allow for IPv6 addresses.
## Usage
You can now set `http-address` and/or `metrics-address` flags to IPv6 addresses.
For example, the following:
`lighthouse bn --http --http-address :: --metrics --metrics-address ::1`
will expose the beacon node HTTP server on `[::]` (equivalent of `0.0.0.0` in IPv4) and the metrics HTTP server on `localhost` (the equivalent of `127.0.0.1` in IPv4)
The beacon node API can then be accessed by:
`curl "http://[server-ipv6-address]:5052/eth/v1/some_endpoint"`
And the metrics server api can be accessed by:
`curl "http://localhost:5054/metrics"` or by `curl "http://[::1]:5054/metrics"`
## Additional Info
On most Linux distributions the `v6only` flag is set to `false` by default (see the section for the `IPV6_V6ONLY` flag in https://www.man7.org/linux/man-pages/man7/ipv6.7.html) which means IPv4 connections will continue to function on a IPv6 address (providing it is appropriately mapped). This means that even if the Lighthouse API is running on `::` it is also possible to accept IPv4 connections.
However on Windows, this is not the case. The `v6only` flag is set to `true` so binding to `::` will only allow IPv6 connections.

## Issue Addressed
This address an issue which was preventing checkpoint-sync.
When the node starts from checkpoint sync, the head block and the finalized block are the same value. We did not respect this when sending a `forkchoiceUpdated` (fcU) call to the EL and were expecting fork choice to hold the *finalized ancestor of the head* and returning an error when it didn't.
This PR uses *only fork choice* for sending fcU updates. This is actually quite nice and avoids some atomicity issues between `chain.canonical_head` and `chain.fork_choice`. Now, whenever `chain.fork_choice.get_head` returns a value we also cache the values required for the next fcU call.
## TODO
- [x] ~~Blocked on #3043~~
- [x] Ensure there isn't a warn message at startup.
## Issue Addressed
Don't send an fcU message at startup if it's pre-genesis. The startup fcU message is not critical, not required by the spec, so it's fine to avoid it for networks that start post-Bellatrix fork.
## Issue Addressed
Resolves#2936
## Proposed Changes
Adds functionality for calling [`validator/prepare_beacon_proposer`](https://ethereum.github.io/beacon-APIs/?urls.primaryName=dev#/Validator/prepareBeaconProposer) in advance.
There is a `BeaconChain::prepare_beacon_proposer` method which, which called, computes the proposer for the next slot. If that proposer has been registered via the `validator/prepare_beacon_proposer` API method, then the `beacon_chain.execution_layer` will be provided the `PayloadAttributes` for us in all future forkchoiceUpdated calls. An artificial forkchoiceUpdated call will be created 4s before each slot, when the head updates and when a validator updates their information.
Additionally, I added strict ordering for calls from the `BeaconChain` to the `ExecutionLayer`. I'm not certain the `ExecutionLayer` will always maintain this ordering, but it's a good start to have consistency from the `BeaconChain`. There are some deadlock opportunities introduced, they are documented in the code.

As discussed on last-night's consensus call, the testnets next week will target the [Kiln Spec v2](https://hackmd.io/@n0ble/kiln-spec).
Presently, we support Kiln V1. V2 is backwards compatible, except for renaming `random` to `prev_randao` in:
- https://github.com/ethereum/execution-apis/pull/180
- https://github.com/ethereum/consensus-specs/pull/2835
With this PR we'll no longer be compatible with the existing Kintsugi and Kiln testnets, however we'll be ready for the testnets next week. I raised this breaking change in the call last night, we are all keen to move forward and break things.
We now target the [`merge-kiln-v2`](https://github.com/MariusVanDerWijden/go-ethereum/tree/merge-kiln-v2) branch for interop with Geth. This required adding the `--http.aauthport` to the tester to avoid a port conflict at startup.
### Changes to exec integration tests
There's some change in the `merge-kiln-v2` version of Geth that means it can't compile on a vanilla Github runner. Bumping the `go` version on the runner solved this issue.
Whilst addressing this, I refactored the `testing/execution_integration` crate to be a *binary* rather than a *library* with tests. This means that we don't need to run the `build.rs` and build Geth whenever someone runs `make lint` or `make test-release`. This is nice for everyday users, but it's also nice for CI so that we can have a specific runner for these tests and we don't need to ensure *all* runners support everything required to build all execution clients.
## More Info
- [x] ~~EF tests are failing since the rename has broken some tests that reference the old field name. I have been told there will be new tests released in the coming days (25/02/22 or 26/02/22).~~
## Issue Addressed
#3006
## Proposed Changes
This PR changes the default behaviour of lighthouse to ignore discovered IPs that are not globally routable. It adds a CLI flag, --enable-local-discovery to permit the non-global IPs in discovery.
NOTE: We should take care in merging this as I will break current set-ups that rely on local IP discovery. I made this the non-default behaviour because we dont really want to be wasting resources attempting to connect to non-routable addresses and we dont want to propagate these to others (on the chance we can connect to one of these local nodes), improving discoveries efficiency.
## Description
This PR adds a single, trivial commit (f5d2b27d78349d5a675a2615eba42cc9ae708094) atop #2986 to resolve a tests compile error. The original author (@ethDreamer) is AFK so I'm getting this one merged ☺️

## Proposed Changes
Adds the functionality to allow blocks to be validated/invalidated after their import as per the [optimistic sync spec](https://github.com/ethereum/consensus-specs/blob/dev/sync/optimistic.md#how-to-optimistically-import-blocks). This means:
- Updating `ProtoArray` to allow flipping the `execution_status` of ancestors/descendants based on payload validity updates.
- Creating separation between `execution_layer` and the `beacon_chain` by creating a `PayloadStatus` struct.
- Refactoring how the `execution_layer` selects a `PayloadStatus` from the multiple statuses returned from multiple EEs.
- Adding testing framework for optimistic imports.
- Add `ExecutionBlockHash(Hash256)` new-type struct to avoid confusion between *beacon block roots* and *execution payload hashes*.
- Add `merge` to [`FORKS`](c3a793fd73/Makefile (L17)) in the `Makefile` to ensure we test the beacon chain with merge settings.
- Fix some tests here that were failing due to a missing execution layer.

This is notably different to the existing lcli code:
- Uses `BlockReplayer` #2863 and as such runs significantly faster than the previous method.
- Corrects the off-by-one #2878
- Removes the `offline` validators component. This was only a "best guess" and simply was used as a way to determine an estimate of the "true" packing efficiency and was generally not helpful in terms of direct comparisons between different packing methods. As such it has been removed from the API and any future estimates of "offline" validators would be better suited in a separate/more targeted API or as part of 'beacon watch': #2873
- Includes `prior_skip_slots`.
## Issue Addressed
Closes#2880
## Proposed Changes
Support requests to the next epoch in proposer_duties api.
## Additional Info
Implemented with skipping proposer cache for this case because the cache for the future epoch will be missed every new slot as dependent_root is changed and we don't want to "wash it out" by saving additional values.
## Issue Addressed
I noticed in some logs some excess and unecessary discovery queries. What was happening was we were pruning our peers down to our outbound target and having some disconnect. When we are below this threshold we try to find more peers (even if we are at our peer limit). The request becomes futile because we have no more peer slots.
This PR corrects this issue and advances the pruning mechanism to favour subnet peers.
An overview the new logic added is:
- We prune peers down to a target outbound peer count which is higher than the minimum outbound peer count.
- We only search for more peers if there is room to do so, and we are below the minimum outbound peer count not the target. So this gives us some buffer for peers to disconnect. The buffer is currently 10%
The modified pruning logic is documented in the code but for reference it should do the following:
- Prune peers with bad scores first
- If we need to prune more peers, then prune peers that are subscribed to a long-lived subnet
- If we still need to prune peers, the prune peers that we have a higher density of on any given subnet which should drive for uniform peers across all subnets.
This will need a bit of testing as it modifies some significant peer management behaviours in lighthouse.

## Issue Addressed

## Proposed Changes
- Rename `receipt_root` to `receipts_root`

- This is slightly weird since we modify everything except the actual HTTP call to the engine API. That change is expected to be implemented in #2985 (cc @ethDreamer)
- Enable "random" tests for Bellatrix.
## Notes
This will break *partially* compatibility with Kintusgi testnets in order to gain compatibility with [Kiln](https://hackmd.io/@n0ble/kiln-spec) testnets. I think it will only break the BN APIs due to the `receipts_root` change, however it might have some other effects too.

## Issue Addressed
On a network with few nodes, it is possible that the same node can be found from a subnet discovery and a normal peer discovery at the same time.
The network behaviour loads these peers into events and processes them when it has the chance. It can happen that the same peer can enter the event queue more than once and then attempt to be dialed twice.
This PR shifts the registration of nodes in the peerdb as being dialed before they enter the NetworkBehaviour queue, preventing multiple attempts of the same peer being entered into the queue and avoiding the race condition.

## Proposed Changes
Adds `STRICT_LATE_MESSAGE_PENALTIES: bool` which allows for toggling penalties for late sync/attn messages.
`STRICT_LATE_MESSAGE_PENALTIES` is set to `false`, since we're seeing a lot of late messages on the network which are causing peer drops. We can toggle the bool during testing to try and figure out what/who is the cause of these late messages.
In effect, this PR *relaxes* peer downscoring for late attns and sync committee messages.
## Additional Info
- ~~Blocked on #2974~~
The gossipsub history was increased to a good portion of a slot from 2.1 seconds in the last release.
Although it shouldn't cause too much issue, it could be related to recieving later messages than usual and interacting with our scoring system penalizing peers. For consistency, this PR reduces the time we gossip messages back to the same values of the previous release.
It also adjusts the gossipsub heartbeat time for testing purposes with a developer flag but this should not effect end users.
## Issue Addressed
This PR fixes the unnecessary `WARN Single block lookup failed` messages described here:
https://github.com/sigp/lighthouse/pull/2866#issuecomment-1008442640
## Proposed Changes
Add a new cache to the `BeaconChain` that tracks the block roots of blocks from before finalization. These could be blocks from the canonical chain (which might need to be read from disk), or old pre-finalization blocks that have been forked out.
The cache also stores a set of block roots for in-progress single block lookups, which duplicates some of the information from sync's `single_block_lookups` hashmap:
a836e180f9/beacon_node/network/src/sync/manager.rs (L192-L196)
On a live node you can confirm that the cache is working by grepping logs for the message: `Rejected attestation to finalized block`.

The API can be used as follows:
```
curl "http://localhost:5052/lighthouse/analysis/attestation_performance/{validator_index}?start_epoch=57730&end_epoch=57732"
```
Alternatively, to compute performances for the global validator set:
```
curl "http://localhost:5052/lighthouse/analysis/attestation_performance/global?start_epoch=57730&end_epoch=57732"
```
### Response
The response is JSON formatted as follows:
```
[
{
"index": 72,
"epochs": {
"57730": {
"active": true,
"head": false,
"target": false,
"source": false
},
"57731": {
"active": true,
"head": true,
"target": true,
"source": true,
"delay": 1
},
"57732": {
"active": true,
"head": true,
"target": true,
"source": true,
"delay": 1
},
}
}
]
```
> Note that the `"epochs"` are not guaranteed to be in ascending order.
## Additional Info
- This API is intended to be used in our upcoming validator analysis tooling (#2873) and will likely not be very useful for regular users. Some advanced users or block explorers may find this API useful however.
- The request range is limited to 100 epochs (since the range is inclusive and it also computes the `end_epoch` it's actually 101 epochs) to prevent Lighthouse using exceptionally large amounts of memory.
Checking how to priorize the polling of the network I moved most of the service code to functions. This change I think it's worth on it's own for code quality since inside the `tokio::select` many tools don't work (cargo fmt, sometimes clippy, and sometimes even the compiler's errors get wack). This is functionally equivalent to the previous code, just better organized
## Proposed Changes
Initially the idea was to remove hashing of blocks in backfill sync. After considering it more, we conclude that we need to do it in both (forward and backfill) anyway. But since we forgot why we were doing it in the first place, this PR documents this logic.
Future us should find it useful

In the latest release we decreased the target number of subnet peers.
It appears this could be causing issues in some cases and so reverting it back to the previous number it wise. A larger PR that follows this will address some other related discovery issues and peer management around subnet peer discovery.
#2923
Which issue # does this PR address?
There's a redundant field on the BeaconChain called disabled_forks that was once part of our fork-aware networking (#953) but which is no longer used and could be deleted. so Removed all references to disabled_forks so that the code compiles and git grep disabled_forks returns no results.
## Proposed Changes

## Issue Addressed
We emit a warning to verify that all peer connection state information is consistent. A warning is given under one edge case;
We try to dial a peer with peer-id X and multiaddr Y. The peer responds to multiaddr Y with a different peer-id, Z. The dialing to the peer fails, but libp2p injects the failed attempt as peer-id Z.
In this instance, our PeerDB tries to add a new peer in the disconnected state under a previously unknown peer-id. This is harmless and so this PR permits this behaviour without logging a warning.
## Issues Addressed
Closes#2739Closes#2812
## Proposed Changes
Support the deserialization of query strings containing duplicate keys into their corresponding types.
As `warp` does not support this feature natively (as discussed in #2739), it relies on the external library [`serde_array_query`](https://github.com/sigp/serde_array_query) (written by @michaelsproul)
This is backwards compatible meaning that both of the following requests will produce the same output:
```
curl "http://localhost:5052/eth/v1/events?topics=head,block"
```
```
curl "http://localhost:5052/eth/v1/events?topics=head&topics=block"
```
## Additional Info
Certain error messages have changed slightly. This only affects endpoints which accept multiple values.
For example:
```
{"code":400,"message":"BAD_REQUEST: invalid query: Invalid query string","stacktraces":[]}
```
is now
```
{"code":400,"message":"BAD_REQUEST: unable to parse query","stacktraces":[]}
```
The serve order of the endpoints `get_beacon_state_validators` and `get_beacon_state_validators_id` have flipped:
```rust
.or(get_beacon_state_validators_id.boxed())
.or(get_beacon_state_validators.boxed())
```
This is to ensure proper error messages when filter fallback occurs due to the use of the `and_then` filter.
## Future Work
- Cleanup / remove filter fallback behaviour by substituting `and_then` with `then` where appropriate.
- Add regression tests for HTTP API error messages.
## Credits
- @mooori for doing the ground work of investigating possible solutions within the existing Rust ecosystem.
- @michaelsproul for writing [`serde_array_query`](https://github.com/sigp/serde_array_query) and for helping debug the behaviour of the `warp` filter fallback leading to incorrect error messages.
## Proposed Changes
Change the canonical fork name for the merge to Bellatrix. Keep other merge naming the same to avoid churn.
I've also fixed and enabled the `fork` and `transition` tests for Bellatrix, and the v1.1.7 fork choice tests.
Additionally, the `BellatrixPreset` has been added with tests. It gets served via the `/config/spec` API endpoint along with the other presets.
## Issue Addressed

## Proposed Changes
In https://github.com/sigp/lighthouse/pull/2832 we made some changes to the `SnapshotCache` to help deal with the one-block reorgs seen on mainnet (and testnets).
I believe the change in #2832 is good and we should keep it, but I think that in its present form it is causing the `SnapshotCache` to hold onto states that it doesn't need anymore. For example, a skip slot will result in one more `BeaconSnapshot` being stored in the cache.
This PR adds a new type of pruning that happens after a block is inserted to the cache. We will remove any snapshot from the cache that is a *grandparent* of the block being imported. Since we know the grandparent has two valid blocks built atop it, it is not at risk from a one-block re-org.
## Additional Info

## Proposed Changes
Allocate less memory in sync by hashing the `SignedBeaconBlock`s in a batch directly, rather than going via SSZ bytes.
Credit to @paulhauner for finding this source of temporary allocations.
## Issue Addressed
The PeerDB was getting out of sync with the number of disconnected peers compared to the actual count. As this value determines how many we store in our cache, over time the cache was depleting and we were removing peers immediately resulting in errors that manifest as unknown peers for some operations.
The error occurs when dialing a peer fails, we were not correctly updating the peerdb counter because the increment to the counter was placed in the wrong order and was therefore not incrementing the count.
This PR corrects this.
There is a pretty significant tradeoff between bandwidth and speed of gossipsub messages.
We can reduce our bandwidth usage considerably at the cost of minimally delaying gossipsub messages. The impact of delaying messages has not been analyzed thoroughly yet, however this PR in conjunction with some gossipsub updates show considerable bandwidth reduction.
This PR allows the user to set a CLI value (`network-load`) which is an integer in the range of 1 of 5 depending on their bandwidth appetite. 1 represents the least bandwidth but slowest message recieving and 5 represents the most bandwidth and fastest received message time.
For low-bandwidth users it is likely to be more efficient to use a lower value. The default is set to 3, which currently represents a reduced bandwidth usage compared to previous version of this PR. The previous lighthouse versions are equivalent to setting the `network-load` CLI to 4.
This PR is awaiting a few gossipsub updates before we can get it into lighthouse.
## Issue Addressed
- Resolves https://github.com/sigp/lighthouse/issues/2902
## Proposed Changes
As documented in https://github.com/sigp/lighthouse/issues/2902, there are some cases where we will score peers very harshly for sending attestations to an unknown head.
This PR removes the penalty when an attestation for an unknown head is received, queued for block look-up, then popped from the queue without the head block being known. This prevents peers from being penalized for an unknown block when that peer was never actually asked for the block.
Peer penalties should still be applied to the peers who *do* get the request for the block and fail to respond with a valid block. As such, peers who send us attestations to non-existent heads should eventually be booted.
## Additional Info
- [ ] Need to confirm that a timeout for a bbroot request will incur a penalty.
## Issue Addressed
NA
## Proposed Changes
We have observed occasions were under-resourced nodes will receive messages that were valid *at the time*, but later become invalidated due to long waits for a `BeaconProcessor` worker.
In this PR, we will check to see if the message was valid *at the time of receipt*. If it was initially valid but invalid now, we just ignore the message without penalizing the peer.
## Additional Info
NA
## Issue Addressed
NA
## Proposed Changes
I've observed some Prater nodes (and potentially some mainnet nodes) banning peers due to validator pubkey cache lock timeouts. For the `BeaconChainError`-type of errors, they're caused by internal faults and we can't necessarily tell if the peer is bad or not. I think this is causing us to ban peers unnecessarily when running on under-resourced machines.

## Issue Addressed

## Proposed Changes
Introduces a cache to attestation to produce atop blocks which will become the head, but are not fully imported (e.g., not inserted into the database).
Whilst attesting to a block before it's imported is rather easy, if we're going to produce that attestation then we also need to be able to:
1. Verify that attestation.
1. Respond to RPC requests for the `beacon_block_root`.
Attestation verification (1) is *partially* covered. Since we prime the shuffling cache before we insert the block into the early attester cache, we should be fine for all typical use-cases. However, it is possible that the cache is washed out before we've managed to insert the state into the database and then attestation verification will fail with a "missing beacon state"-type error.
Providing the block via RPC (2) is also partially covered, since we'll check the database *and* the early attester cache when responding a blocks-by-root request. However, we'll still omit the block from blocks-by-range requests (until the block lands in the DB). I *think* this is fine, since there's no guarantee that we return all blocks for those responses.
Another important consideration is whether or not the *parent* of the early attester block is available in the databse. If it were not, we might fail to respond to blocks-by-root request that are iterating backwards to collect a chain of blocks. I argue that *we will always have the parent of the early attester block in the database.* This is because we are holding the fork-choice write-lock when inserting the block into the early attester cache and we do not drop that until the block is in the database.
## Issue Addressed
The fee-recipient argument of the beacon node does not allow a value to be specified:

## Proposed Changes
Allow specifying a value for the fee-recipient argument in beacon_node/src/cli.rs
## Additional Info
I've added .takes_value(true) and successfully proposed a block in the kintsugi testnet with my own fee-recipient address instead of the hardcoded default. I think that was just missed as the argument does not make sense without a value :)

## Proposed Changes
Ensures full roots are printed, rather than shortened versions like `0x935b…d376`.
For example, it would be nice if we could do API queries based upon the roots shown in the `Beacon chain re-org` event:
```
Jan 05 12:36:52.224 WARN Beacon chain re-org reorg_distance: 2, new_slot: 2073184, new_head: 0x8a97…2dec, new_head_parent: 0xa985…7688, previous_slot: 2073183, previous_head: 0x935b…d376, service: beacon
Jan 05 13:35:05.832 WARN Beacon chain re-org reorg_distance: 1, new_slot: 2073475, new_head: 0x9207…c6b9, new_head_parent: 0xb2ce…839b, previous_slot: 2073474, previous_head: 0x8066…92f7, service: beacon
```
## Additional Info
We should eventually fix this project-wide, however this is a short-term patch.
## Proposed Changes
Update `superstruct` to bring in @realbigsean's fixes necessary for MEV-compatible private beacon block types (a la #2795).
The refactoring is due to another change in superstruct that allows partial getters to be auto-generated.
## Issue Addressed
N/A
## Proposed Changes
We are currently treating errors from the EL on `engine_executePayload` as `PayloadVerificationStatus::NotVerified`. This adds the block as a candidate head block in fork choice even if the EL explicitly rejected the block as invalid.
`PayloadVerificationStatus::NotVerified` should be only returned when the EL explicitly returns "syncing" imo. This PR propagates an error instead of returning `NotVerified` on EL all EL errors.

Part II of major slasher optimisations after #2767
These changes will be backwards-incompatible due to the move to MDBX (and the schema change) 😱
* [x] Shrink attester keys from 16 bytes to 7 bytes.
* [x] Shrink attester records from 64 bytes to 6 bytes.
* [x] Separate `DiskConfig` from regular `Config`.
* [x] Add configuration for the LRU cache size.
* [x] Add a "migration" that deletes any legacy LMDB database.
## Issue Addressed
Successor to #2431
## Proposed Changes
* Add a `BlockReplayer` struct to abstract over the intricacies of calling `per_slot_processing` and `per_block_processing` while avoiding unnecessary tree hashing.
* Add a variant of the forwards state root iterator that does not require an `end_state`.
* Use the `BlockReplayer` when reconstructing states in the database. Use the efficient forwards iterator for frozen states.
* Refactor the iterators to remove `Arc<HotColdDB>` (this seems to be neater than making _everything_ an `Arc<HotColdDB>` as I did in #2431).
Supplying the state roots allow us to avoid building a tree hash cache at all when reconstructing historic states, which saves around 1 second flat (regardless of `slots-per-restore-point`). This is a small percentage of worst-case state load times with 200K validators and SPRP=2048 (~15s vs ~16s) but a significant speed-up for more frequent restore points: state loads with SPRP=32 should be now consistently <500ms instead of 1.5s (a ~3x speedup).

## Proposed Changes
Not counting dialing peers while deciding if we have reached the target peers in case of outbound peers.
## Additional Info
Checked this running in nodes and bandwidth looks normal, peer count looks normal too
## Proposed Changes
Remove the `is_first_block_in_epoch` logic from the balances cache update logic, as it was incorrect in the case of skipped slots. The updated code is simpler because regardless of whether the block is the first in the epoch we can check if an entry for the epoch boundary root already exists in the cache, and update the cache accordingly.
Additionally, to assist with flip-flopping justified epochs, move to cloning the balance cache rather than moving it. This should still be very fast in practice because the balances cache is a ~1.6MB `Vec`, and this operation is expected to only occur infrequently.
## Issue Addressed
Resolves: https://github.com/sigp/lighthouse/issues/2741
Includes: https://github.com/sigp/lighthouse/pull/2853 so that we can get ssz static tests passing here on v1.1.6. If we want to merge that first, we can make this diff slightly smaller
## Proposed Changes
- Changes the `justified_epoch` and `finalized_epoch` in the `ProtoArrayNode` each to an `Option<Checkpoint>`. The `Option` is necessary only for the migration, so not ideal. But does allow us to add a default logic to `None` on these fields during the database migration.
- Adds a database migration from a legacy fork choice struct to the new one, search for all necessary block roots in fork choice by iterating through blocks in the db.
- updates related to https://github.com/ethereum/consensus-specs/pull/2727
- We will have to update the persisted forkchoice to make sure the justified checkpoint stored is correct according to the updated fork choice logic. This boils down to setting the forkchoice store's justified checkpoint to the justified checkpoint of the block that advanced the finalized checkpoint to the current one.
- AFAICT there's no migration steps necessary for the update to allow applying attestations from prior blocks, but would appreciate confirmation on that
- I updated the consensus spec tests to v1.1.6 here, but they will fail until we also implement the proposer score boost updates. I confirmed that the previously failing scenario `new_finalized_slot_is_justified_checkpoint_ancestor` will now pass after the boost updates, but haven't confirmed _all_ tests will pass because I just quickly stubbed out the proposer boost test scenario formatting.
- This PR now also includes proposer boosting https://github.com/ethereum/consensus-specs/pull/2730
## Additional Info
I realized checking justified and finalized roots in fork choice makes it more likely that we trigger this bug: https://github.com/ethereum/consensus-specs/pull/2727
It's possible the combination of justified checkpoint and finalized checkpoint in the forkchoice store is different from in any block in fork choice. So when trying to startup our store's justified checkpoint seems invalid to the rest of fork choice (but it should be valid). When this happens we get an `InvalidBestNode` error and fail to start up. So I'm including that bugfix in this branch.
Todo:
- [x] Fix fork choice tests
- [x] Self review
- [x] Add fix for https://github.com/ethereum/consensus-specs/pull/2727
- [x] Rebase onto Kintusgi
- [x] Fix `num_active_validators` calculation as @michaelsproul pointed out
- [x] Clean up db migrations

Various Changes to Conform Closer to Merge Spec
## Issue Addressed
Closes#1996
## Proposed Changes
Run a second `Logger` via `sloggers` which logs to a file in the background with:
- separate `debug-level` for background and terminal logging
- the ability to limit log size
- rotation through a customizable number of log files
- an option to compress old log files (`.gz` format)
Add the following new CLI flags:
- `--logfile-debug-level`: The debug level of the log files
- `--logfile-max-size`: The maximum size of each log file
- `--logfile-max-number`: The number of old log files to store
- `--logfile-compress`: Whether to compress old log files
By default background logging uses the `debug` log level and saves logfiles to:
- Beacon Node: `$HOME/.lighthouse/$network/beacon/logs/beacon.log`
- Validator Client: `$HOME/.lighthouse/$network/validators/logs/validator.log`
Or, when using the `--datadir` flag:
`$datadir/beacon/logs/beacon.log` and `$datadir/validators/logs/validator.log`
Once rotated, old logs are stored like so: `beacon.log.1`, `beacon.log.2` etc.
> Note: `beacon.log.1` is always newer than `beacon.log.2`.
## Additional Info
Currently the default value of `--logfile-max-size` is 200 (MB) and `--logfile-max-number` is 5.
This means that the maximum storage space that the logs will take up by default is 1.2GB.
(200MB x 5 from old log files + <200MB the current logfile being written to)
Happy to adjust these default values to whatever people think is appropriate.
It's also worth noting that when logging to a file, we lose our custom `slog` formatting. This means the logfile logs look like this:
```

## Issue Addressed
Users are experiencing `Status'd peer not found` errors
## Proposed Changes
Although I cannot reproduce this error, this is only one connection state change that is not addressed in the peer manager (that I could see). The error occurs because the number of disconnected peers in the peerdb becomes out of sync with the actual number of disconnected peers. From what I can tell almost all possible connection state changes are handled, except for the case when a disconnected peer changes to be disconnecting. This can potentially happen at the peer connection limit, where a previously connected peer switches to disconnecting.
This PR decrements the disconnected counter when this event occurs and from what I can tell, covers all possible disconnection state changes in the peer manager.
We were batch removing chains when purging, and then updating the status of the collection for each of those. This makes the range status be out of sync with the real status. This represented no harm to the global sync status, but I've changed it to comply with a correct debug assertion that I got triggered while doing some testing.
Also added tests and improved code quality as per @paulhauner 's suggestions.

## Proposed Changes
1. Don't disconnect peer from dht on connection limit errors
2. Bump up `PRIORITY_PEER_EXCESS` to allow for dialing upto 60 peers by default.
Co-authored-by: Diva M <divma@protonmail.com>
I had this change but it seems to have been lost in chaos of network upgrades.
The swarm dialing event seems to miss some cases where we dial via the behaviour. This causes an error to be logged as the peer manager doesn't know about some dialing events.
This shifts the logic to the behaviour to inform the peer manager.
## Issue Addressed
Part of a bigger effort to make the network globals read only. This moves all writes to the `PeerDB` to the `eth2_libp2p` crate. Limiting writes to the peer manager is a slightly more complicated issue for a next PR, to keep things reviewable.
## Proposed Changes
- Make the peers field in the globals a private field.
- Allow mutable access to the peers field to `eth2_libp2p` for now.
- Add a new network message to update the sync state.

## Issue Addressed
Running a beacon node I triggered a sync debug panic. And so finally the time to create tests for sync arrived. Fortunately, te bug was not in the sync algorithm itself but a wrong assertion
## Proposed Changes
- Split Range's impl from the BeaconChain via a trait. This is needed for testing. The TestingRig/Harness is way bigger than needed and does not provide the modification functionalities that are needed to test sync. I find this simpler, tho some could disagree.
- Add a regression test for sync that fails before the changes.
- Fix the wrong assertion.
RPC Responses are for some reason not removing their timeout when they are completing.

This PR is to investigate and correct the issue.
~~My current thoughts are that for some reason we are not closing the streams correctly, or fast enough, or the executor is not registering the closes and waking up.~~ - Pretty sure this is not the case, see message below for a more accurate reason.
~~I've currently added a timeout to stream closures in an attempt to force streams to close and the future to always complete.~~ I removed this
