bc14d1d73d Add more unix signal handlers (#2486)
## Issue Addressed

Resolves #2114 

Swapped out the ctrlc crate for tokio signals to hook register handlers for SIGPIPE and SIGHUP along with SIGTERM and SIGINT.

## Proposed Changes

- Swap out the ctrlc crate for tokio signals for unix signal handing
- Register signals for SIGPIPE and SHIGUP that trigger the same shutdown procedure as SIGTERM and SIGINT

## Additional Info

I tested these changes against the examples in the original issue and noticed some interesting behavior on my machine. When running `lighthouse bn --network pyrmont |& tee -a pyrmont_bn.log` or `lighthouse bn --network pyrmont 2>&1 | tee -a pyrmont_bn.log` none of the above signals are sent to the lighthouse program in a way I was able to observe. 

The only time it seems that the signal gets sent to the lighthouse program is if there is no redirection of stderr to stdout. I'm not as familiar with the details of how unix signals work in linux with a redirect like that so I'm not sure if this is a bug in the program or expected behavior.

Signals are correctly received without the redirection and if the above signals are sent directly to the program with something like `kill`.

99737c551a Improve eth1 fallback logging (#2490)
## Issue Addressed

Resolves #2487 

## Proposed Changes

Logs a message once in every invocation of `Eth1Service::update` method if the primary endpoint is unavailable for some reason. 

e.g.
```log
Aug 03 00:09:53.517 WARN Error connecting to eth1 node endpoint  action: trying fallbacks, endpoint: http://localhost:8545/, service: eth1_rpc
Aug 03 00:09:56.959 INFO Fetched data from fallback              fallback_number: 1, service: eth1_rpc
```

The main aim of this PR is to have an accompanying message to the "action: trying fallbacks" error message that is returned when checking the endpoint for liveness. This is mainly to indicate to the user that the fallback was live and reachable. 

## Additional info
This PR is not meant to be a catch all for all cases where the primary endpoint failed. For instance, this won't log anything if the primary node was working fine during endpoint liveness checking and failed during deposit/block fetching. This is done intentionally to reduce number of logs while initial deposit/block sync and to avoid more complicated logic.

4405425726 Expand gossip duplicate cache time (#2542)
## Issue Addressed

NA

## Proposed Changes

This PR expands the time that entries exist in the gossip-sub duplicate cache. Recent investigations found that this cache is one slot (12s) shorter than the period for which an attestation is permitted to propagate on the gossip network.

Before #2540, this was causing peers to be unnecessarily down-scored for sending old attestations. Although that issue has been fixed, the duplicate cache time is increased here to avoid such messages from getting any further up the networking stack then required.

3fdad38eba Remove penality for duplicate attestation from same validator (#2540)
## Issue Addressed

NA

## Proposed Changes

A Discord user presented logs which indicated a drop in their peer count caused by a variety of peers sending attestations where we'd already seen an attestation for that validator. It's presently unclear how this case came about, but during our investigation I noticed that we are down-voting peers for sending such attestations.

There are three scenarios where we may receive duplicate unagg. attestations from the same validator:

1. The validator is committing a slashable offense.
2. The gossipsub message-deduping functionality is not working as expected.
3. We received the message via the HTTP prior to seeing it via gossip.

Scenario (1) would be so costly for an attacker that I don't think we need to add DoS protection for it.

Scenario (2) seems feasible. Our "seen message" caches in gossipsub might fill up/expire and let through these duplicates. There are also cases involving message ID mismatches with the other peers. In both these cases, I don't think we should be doing 1 attestation == -1 point down-voting.

Scenario (3) is not necessarily a fault of the peer and we shouldn't down-score them for it.

02fd54bea7 Refactor discovery queries (#2518)
## Issue Addressed

N/A

## Proposed Changes

Refactor discovery queries such that only `QueryType::Subnet` queries are queued for grouping. `QueryType::FindPeers` is always made regardless of the number of active `Subnet` queries (max = 2). This prevents `FindPeers` queries from getting starved if `Subnet` queries start queuing up. 

Also removes `GroupedQueryType` struct and use `QueryType` for all queuing and processing of discovery requests.

## Additional Info

Currently, no distinction is made between subnet discovery queries for attestation and sync committee subnets when grouping queries. Potentially we could prioritise attestation queries over sync committee queries in the future.

c0a2f501d9 Upgrade dependencies (#2513)
## Proposed Changes

* Consolidate Tokio versions: everything now uses the latest v1.10.0, no more `tokio-compat`.
* Many semver-compatible changes via `cargo update`. Notably this upgrades from the yanked v0.8.0 version of crossbeam-deque which is present in v1.5.0-rc.0
* Many semver incompatible upgrades via `cargo upgrades` and `cargo upgrade --workspace pkg_name`. Notable ommissions:
    - Prometheus, to be handled separately: https://github.com/sigp/lighthouse/issues/2485
    - `rand`, `rand_xorshift`: the libsecp256k1 package requires 0.7.x, so we'll stick with that for now
    - `ethereum-types` is pinned at 0.11.0 because that's what `web3` is using and it seems nice to have just a single version
    
## Additional Info

We still have two versions of `libp2p-core` due to `discv5` depending on the v0.29.0 release rather than `master`. AFAIK it should be OK to release in this state (cc @AgeManning )

54f92cc263 Use THC for state.inactivity_scores (#2504)
## Issue Addressed

- Resolves #2502

## Proposed Changes

Adds tree-hash caching (THC 🍁) for `state.inactivity_scores`, as per #2502.

Since the `inactivity_scores` field is introduced during Altair, the cache must be optional (i.e., not present pre-Altair). The mechanism for optional caches was already implemented via the `ParticipationTreeHashCache`, albeit not quite generically enough. To this end, I made the `ParticipationTreeHashCache` more generic and renamed it to `OptionalTreeHashCache`. This made the code a little more verbose around the previous/current epoch participation fields, but overall less verbose when the needs of `inactivity_scores` are considered.

All changes to `ParticipationTreeHashCache` should be *non-substantial*.

ceda27371d Ensure doppelganger detects attestations in blocks (#2495)
## Issue Addressed

NA

## Proposed Changes

When testing our (not-yet-released) Doppelganger implementation, I noticed that we aren't detecting attestations included in blocks (only those on the gossip network).

This is because during [block processing](e8c0d1f19b/beacon_node/beacon_chain/src/beacon_chain.rs (L2168)) we only update the `observed_attestations` cache with each attestation, but not the `observed_attesters` cache. This is the correct behaviour when we consider the [p2p spec](https://github.com/ethereum/eth2.0-specs/blob/v1.0.1/specs/phase0/p2p-interface.md):

> [IGNORE] There has been no other valid attestation seen on an attestation subnet that has an identical attestation.data.target.epoch and participating validator index.

We're doing the right thing here and still allowing attestations on gossip that we've seen in a block. However, this doesn't work so nicely for Doppelganger.

To resolve this, I've taken the following steps:

- Add a `observed_block_attesters` cache.
- Rename `observed_attesters` to `observed_gossip_attesters`.

## TODO

- [x] Add a test to ensure a validator that's been seen in a block attestation (but not a gossip attestation) returns `true` for `BeaconChain::validator_seen_at_epoch`.
- [x] Add a test to ensure `observed_block_attesters` isn't polluted via gossip attestations and vice versa.

6a620a31da Fix starting-epoch check in doppelganger (#2491)
## Issue Addressed

NA

## Proposed Changes

Fixes a bug in Doppelganger Protection which would cause false-positives when a VC is restarted in the same epoch where it has already produced a signed message.

It could also cause a false-negative in the scenario where time skips forward (perhaps due to host suspend/wake). The new `time_skips_forward_with_doppelgangers` test covers this case.

This was a simple (and embarrassing, on my behalf) `>=` instead of `<=` bug that was missed by my tests but detected during manual testing by @michaelsproul (🙏). Regression tests have been added.

c5786a8821 Doppelganger detection (#2230)
## Issue Addressed

Resolves #2069 

## Proposed Changes

- Adds a `--doppelganger-detection` flag
- Adds a `lighthouse/seen_validators` endpoint, which will make it so the lighthouse VC is not interopable with other client beacon nodes if the `--doppelganger-detection` flag is used, but hopefully this will become standardized. Relevant Eth2 API repo issue: https://github.com/ethereum/eth2.0-APIs/issues/64
- If the `--doppelganger-detection` flag is used, the VC will wait until the beacon node is synced, and then wait an additional 2 epochs. The reason for this is to make sure the beacon node is able to subscribe to the subnets our validators should be attesting on. I think an alternative would be to have the beacon node subscribe to all subnets for 2+ epochs on startup by default.

## Additional Info

I'd like to add tests and would appreciate feedback. 

TODO:  handle validators started via the API, potentially make this default behavior

8efd9fc324 Add AttesterCache for attestation production (#2478)
## Issue Addressed

- Resolves #2169

## Proposed Changes

Adds the `AttesterCache` to allow validators to produce attestations for older slots. Presently, some arbitrary restrictions can force validators to receive an error when attesting to a slot earlier than the present one. This can cause attestation misses when there is excessive load on the validator client or time sync issues between the VC and BN.

923486f34c Use bulk verification for sync_aggregate signature (#2415)
## Proposed Changes

Add the `sync_aggregate` from `BeaconBlock` to the bulk signature verifier for blocks. This necessitates a new signature set constructor for the sync aggregate, which is different from the others due to the use of [`eth2_fast_aggregate_verify`](https://github.com/ethereum/eth2.0-specs/blob/v1.1.0-alpha.7/specs/altair/bls.md#eth2_fast_aggregate_verify) for sync aggregates, per [`process_sync_aggregate`](https://github.com/ethereum/eth2.0-specs/blob/v1.1.0-alpha.7/specs/altair/beacon-chain.md#sync-aggregate-processing). I made the choice to return an optional signature set, with `None` representing the case where the signature is valid on account of being the point at infinity (requires no further checking).

To "dogfood" the changes and prevent duplication, the consensus logic now uses the signature set approach as well whenever it is required to verify signatures (which should only be in testing AFAIK). The EF tests pass with the code as it exists currently, but failed before I adapted the `eth2_fast_aggregate_verify` changes (which is good).

As a result of this change Altair block processing should be a little faster, and importantly, we will no longer accidentally verify signatures when replaying blocks, e.g. when replaying blocks from the database.

6e3ca48cb9 Cache participating indices for Altair epoch processing (#2416)
## Issue Addressed

NA

## Proposed Changes

This PR addresses two things:

1. Allows the `ValidatorMonitor` to work with Altair states.
1. Optimizes `altair::process_epoch` (see [code](https://github.com/paulhauner/lighthouse/blob/participation-cache/consensus/state_processing/src/per_epoch_processing/altair/participation_cache.rs) for description)

## Breaking Changes

The breaking changes in this PR revolve around one premise:

*After the Altair fork, it's not longer possible (given only a `BeaconState`) to identify if a validator had *any* attestation included during some epoch. The best we can do is see if that validator made the "timely" source/target/head flags.*

Whilst this seems annoying, it's not actually too bad. Finalization is based upon "timely target" attestations, so that's really the most important thing. Although there's *some* value in knowing if a validator had *any* attestation included, it's far more important to know about "timely target" participation, since this is what affects finality and justification.

For simplicity and consistency, I've also removed the ability to determine if *any* attestation was included from metrics and API endpoints. Now, all Altair and non-Altair states will simply report on the head/target attestations.

The following section details where we've removed fields and provides replacement values.

### Breaking Changes: Prometheus Metrics

Some participation metrics have been removed and replaced. Some were removed since they are no longer relevant to Altair (e.g., total attesting balance) and others replaced with gwei values instead of pre-computed values. This provides more flexibility at display-time (e.g., Grafana).

The following metrics were added as replacements:

- `beacon_participation_prev_epoch_head_attesting_gwei_total`
- `beacon_participation_prev_epoch_target_attesting_gwei_total`
- `beacon_participation_prev_epoch_source_attesting_gwei_total`
- `beacon_participation_prev_epoch_active_gwei_total`

The following metrics were removed:

- `beacon_participation_prev_epoch_attester`
   - instead use `beacon_participation_prev_epoch_source_attesting_gwei_total / beacon_participation_prev_epoch_active_gwei_total`.
- `beacon_participation_prev_epoch_target_attester`
   - instead use `beacon_participation_prev_epoch_target_attesting_gwei_total / beacon_participation_prev_epoch_active_gwei_total`.
- `beacon_participation_prev_epoch_head_attester`
   - instead use `beacon_participation_prev_epoch_head_attesting_gwei_total / beacon_participation_prev_epoch_active_gwei_total`.

The `beacon_participation_prev_epoch_attester` endpoint has been removed. Users should instead use the pre-existing `beacon_participation_prev_epoch_target_attester`. 

### Breaking Changes: HTTP API

The `/lighthouse/validator_inclusion/{epoch}/{validator_id}` endpoint loses the following fields:

- `current_epoch_attesting_gwei` (use `current_epoch_target_attesting_gwei` instead)
- `previous_epoch_attesting_gwei` (use `previous_epoch_target_attesting_gwei` instead)

The `/lighthouse/validator_inclusion/{epoch}/{validator_id}` endpoint lose the following fields:

- `is_current_epoch_attester` (use `is_current_epoch_target_attester` instead)
- `is_previous_epoch_attester` (use `is_previous_epoch_target_attester` instead)
- `is_active_in_current_epoch` becomes `is_active_unslashed_in_current_epoch`.
- `is_active_in_previous_epoch` becomes `is_active_unslashed_in_previous_epoch`.

## Additional Info

NA

## TODO

- [x] Deal with total balances
- [x] Update validator_inclusion API
- [ ] Ensure `beacon_participation_prev_epoch_target_attester` and `beacon_participation_prev_epoch_head_attester` work before Altair

f5bdca09ff Update to spec v1.1.0-beta.1 (#2460)
## Proposed Changes

Update to the latest version of the Altair spec, which includes new tests and a tweak to the target sync aggregators.

## Additional Info

This change is _not_ required for the imminent Altair devnet, and is waiting on the merge of #2321 to unstable.

84e6d71950 Tree hash caching and optimisations for Altair (#2459)
## Proposed Changes

Remove the remaining Altair `FIXME`s from consensus land.

1. Implement tree hash caching for the participation lists. This required some light type manipulation, including removing the `TreeHash` bound from `CachedTreeHash` which was purely descriptive.
2. Plumb the proposer index through Altair attestation processing, to avoid calculating it for _every_ attestation (potentially 128ms on large networks). This duplicates some work from #2431, but with the aim of getting it in sooner, particularly for the Altair devnets.
3. Removes two FIXMEs related to `superstruct` and cloning, which are unlikely to be particularly detrimental and will be tracked here instead: https://github.com/sigp/superstruct/issues/5

17b6d7ce86 Add http-address flag to VC (#2467)
## Issue Addressed

#2454 

## Proposed Changes

Adds the `--http-address` flag to allow the user to use custom HTTP addresses. This can be helpful for certain Docker setups.

Since using custom HTTP addresses is unsafe due to the server being unencrypted,  `--unencrypted-http-transport` was also added as a safety flag and must be used in tandem with `--http-address`. This is to ensure the user is aware of the risks associated with using non-local HTTP addresses.

bcf8ba6318 Add lcli Dockerfile and auto-build to CI (#2469)
## Issue Addressed

Resolves: #2087

## Proposed Changes

- Add a `Dockerfile` to the `lcli` directory
- Add a github actions job to build and push and `lcli` docker image on pushes to `unstable` and `stable`

## Additional Info

It's a little awkward but `lcli` requires the full project scope so must be built: 
- from the `lighthouse` dir with: `docker build -f ./lcli/Dockerflie .`
- from the `lcli` dir with: `docker build -f ./Dockerfile ../`

Didn't include `libssl-dev` or `ca-certificates`, `lcli` doesn't need these right?
