0b319d4926 Inform dialing via the behaviour (#2814)
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.

53562010ec Move peer db writes to eth2 libp2p (#2724)
## 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.

31386277c3 Sync wrong dbg assertion (#2821)
## 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.

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

58b04acf28 Fix simulator issues (#2802)
## Issue Addressed

Resolves #2775 

## Proposed Changes

1. Reduces the target_peers to stop recursive discovery requests.
2. Changes the eth1 `auto_update_interval` config parameter to be equal to the eth1 block time in the simulator. Without this, the eth1 `latest_cached_block` wouldn't be updated for some slots around `eth1_voting_period` boundaries which would lead to the eth1 cache falling out of sync. This is what caused the `Syncing eth1 block cache` and `No valid eth1_data votes` logs.

931daa40d7 Add fork choice EF tests (#2737)
## Issue Addressed

Resolves #2545

## Proposed Changes

Adds the long-overdue EF tests for fork choice. Although we had pretty good coverage via other implementations that closely followed our approach, it is nonetheless important for us to implement these tests too.

During testing I found that we were using a hard-coded `SAFE_SLOTS_TO_UPDATE_JUSTIFIED` value rather than one from the `ChainSpec`. This caused a failure during a minimal preset test. This doesn't represent a risk to mainnet or testnets, since the hard-coded value matched the mainnet preset.

## Failing Cases

There is one failing case which is presently marked as `SkippedKnownFailure`:

```
case 4 ("new_finalized_slot_is_justified_checkpoint_ancestor") from /home/paul/development/lighthouse/testing/ef_tests/consensus-spec-tests/tests/minimal/phase0/fork_choice/on_block/pyspec_tests/new_finalized_slot_is_justified_checkpoint_ancestor failed with NotEqual:
head check failed: Got Head { slot: Slot(40), root: 0x9183dbaed4191a862bd307d476e687277fc08469fc38618699863333487703e7 } | Expected Head { slot: Slot(24), root: 0x105b49b51bf7103c182aa58860b039550a89c05a4675992e2af703bd02c84570 }
```

This failure is due to #2741. It's not a particularly high priority issue at the moment, so we fix it after merging this PR.

d01fe02824 Add regression tests for boot_node (#2749)
## Issue Addressed
Resolves #2602

## Proposed Changes

*Note: For a review it might help to look at the individual commits.*

### `boot_node`
Add support for the flags `dump-config` and `immediate-shutdown`. For `immediate-shutdown` the actual behavior could be described as `dump-config-and-exit`.

Both flags are handled in `boot_node::main`, which appears to be the simplest approach.

### `boot_node` regression tests
Added in `lighthouse/tests/boot_node.rs`.

### `CommandLineTestExec`
Factors out boilerplate related to CLI tests. It's used in the regression tests for `boot_node`, `beacon_node` and `validator_client`.

## Open TODO
Add tests for `boot_node` flags `enable-enr-auto-update` and `disable-packet-filter`. They end up in [`Discv5Config`](9ed2cba6bc/boot_node/src/config.rs (L29)), which doesn't support serde (de)serialization.

I haven't found a workaround - guidance would be appreciated.

fbafe416d1 Move the peer manager to be a behaviour (#2773)
This simply moves some functions that were "swarm notifications" to a network behaviour implementation.

Notes
------
- We could disconnect from the peer manager but we would lose the rpc shutdown message
- We still notify from the swarm since this is the most reliable way to get some events. Ugly but best for now
- Events need to be pushed with "add event" to wake the waker

df02639b71 De-duplicate attestations in the slasher (#2767)
## Issue Addressed

Closes https://github.com/sigp/lighthouse/issues/2112
Closes https://github.com/sigp/lighthouse/issues/1861

## Proposed Changes

Collect attestations by validator index in the slasher, and use the magic of reference counting to automatically discard redundant attestations. This results in us storing only 1-2% of the attestations observed when subscribed to all subnets, which carries over to a 50-100x reduction in data stored 🎉 

## Additional Info

There's some nuance to the configuration of the `slot-offset`. It has a profound effect on the effictiveness of de-duplication, see the docs added to the book for an explanation: 5442e695e5/book/src/slasher.md (slot-offset)

2ed6775dcf Add cargo vendor test (#2076)
## Issue Addressed

This is related to #1926 and #1712.

## Proposed Changes

This PR adds a test that make sure that the used dependencies can be vendored.

Being able to vendor the dependencies is important for archival and repdroducibility purpose.
It's also required to package lighthouse for some Linux distributions. Specifically [NixOS](https://nixos.org/) and [Yocto](https://www.yoctoproject.org/).

## Additional Info

This PR only adds the test, it doesn't clean up the dependencies yet. That's why it is in draft.

7502970a7d Do not compute metrics in the network service if the cli flag is not set (#2765)
## Issue Addressed

The computation of metrics in the network service can be expensive. This disables the computation unless the cli flag `metrics` is set.

## Additional Info
Metrics in other parts of the network are still updated, since most are simple metrics and checking if metrics are enabled each time each metric is updated doesn't seem like a gain.

c4ad0e3fb3 Ensure dependent root consistency in head events (#2753)
## Issue Addressed

@paulhauner noticed that when we send head events, we use the block root from `new_head` in `fork_choice_internal`, but calculate `dependent_root` and `previous_dependent_root` using the `canonical_head`. This is normally fine because `new_head` updates the `canonical_head` in `fork_choice_internal`, but it's possible we have a reorg updating `canonical_head` before our head events are sent. So this PR ensures `dependent_root` and `previous_dependent_root` are always derived from the state associated with `new_head`.

80627b428b Fix linting error on Windows (#2759)
While testing some code on Windows, I ran into a failure when using `clippy` via (`make lint`):
```

    = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#needless_borrow
    
error: could not compile `filesystem` due to previous error
```

## Proposed Changes

Remove the unnecessary borrow as suggested.

## Additional Info

Since we are only running `clippy` in CI on Ubuntu, I believe we don't have any way (in CI) to detect these Windows specific lint errors (either from new code, or from linting changes from new Rust versions. 
This is because code marked as `#[cfg(windows)]` is not checked on `unix` systems and vice versa.

I'm conscious that our CI runs are already taking a long time, and that adding a new Windows `clippy` run would add a non-negligible amount of time to the runs (not sure if this topic has already been discussed), but it something to be aware of.

## Extra Note
I don't think this is the case, but it might be worth someone else running `make lint` on their Windows machines to eliminate the possibility that this is an error specific to my setup.

4499adc7fd Check proposer index during block production (#2740)
## Issue Addressed

Resolves #2612 

## Proposed Changes

Implements both the checks mentioned in the original issue. 
1. Verifies the `randao_reveal` in the beacon node
2. Cross checks the proposer index after getting back the block from the beacon node.

## Additional info
The block production time increases by ~10x because of the signature verification on the beacon node (based on the `beacon_block_production_process_seconds` metric) when running on a local testnet.

2c4413454a Fixed Gossip Topics on Fork Boundary (#2619)
## Issue Addressed

The [p2p-interface section of the `altair` spec](https://github.com/ethereum/consensus-specs/blob/dev/specs/altair/p2p-interface.md#transitioning-the-gossip) says you should subscribe to the topics for a fork "In advance of the fork" and unsubscribe from old topics `2 Epochs` after the new fork is activated. We've chosen to subscribe to new fork topics `2 slots` before the fork is initiated.

This function is supposed to return the required fork digests at any given time but as it was currently written, it doesn't return the fork digest for a previous fork if you've switched to the current fork less than 2 epoch's ago. Also this function required modification for every new fork we add.

## Proposed Changes

Make this function fork-agnostic and correctly handle the previous fork topic digests when you've only just switched to the new fork.

88063398f6 Prevent double import of blocks (#2647)
## Issue Addressed

Resolves #2611 

## Proposed Changes

Adds a duplicate block root cache to the `BeaconProcessor`. Adds the block root to the cache before calling `process_gossip_block` and `process_rpc_block`. Since `process_rpc_block` is called only for single block lookups, we don't have to worry about batched block imports.

The block is imported from the source(gossip/rpc) that arrives first. The block that arrives second is not imported to avoid the db access issue.
There are 2 cases:
1. Block that arrives second is from rpc: In this case, we return an optimistic `BlockError::BlockIsAlreadyKnown` to sync.
2. Block that arrives second is from gossip: In this case, we only do gossip verification and forwarding but don't import the block into the the beacon chain.

## Additional info
Splits up `process_gossip_block` function to `process_gossip_unverified_block` and `process_gossip_verified_block`.

2dc6163043 Add API version headers and map_fork_name! (#2745)
## Proposed Changes

* Add the `Eth-Consensus-Version` header to the HTTP API for the block and state endpoints. This is part of the v2.1.0 API that was recently released: https://github.com/ethereum/beacon-APIs/pull/170
* Add tests for the above. I refactored the `eth2` crate's helper functions to make this more straight-forward, and introduced some new mixin traits that I think greatly improve readability and flexibility.
* Add a new `map_with_fork!` macro which is useful for decoding a superstruct type without naming all its variants. It is now used for SSZ-decoding `BeaconBlock` and `BeaconState`, and for JSON-decoding `SignedBeaconBlock` in the API.

## Additional Info

The `map_with_fork!` changes will conflict with the Merge changes, but when resolving the conflict the changes from this branch should be preferred (it is no longer necessary to enumerate every fork). The merge fork _will_  need to be added to `map_fork_name_with`.

8edd9d45ab Fix purge-db edge case (#2747)
## Issue Addressed

Currently, if you launch the beacon node with the `--purge-db` flag and the `beacon` directory exists, but one (or both) of the `chain_db` or `freezer-db` directories are missing, it will error unnecessarily with: 
```
Failed to remove chain_db: No such file or directory (os error 2)
```

This is an edge case which can occur in cases of manual intervention (a user deleted the directory) or if you had previously run with the `--purge-db` flag and Lighthouse errored before it could initialize the db directories.

## Proposed Changes

Check if the `chain_db`/`freezer_db` exists before attempting to remove them. This prevents unnecessary errors.

99f7a7db58 remove double backfill sync state (#2733)
## Issue Addressed
In the backfill sync the state was maintained twice, once locally and also in the globals. This makes it so that it's maintained only once.

The only behavioral change is that when backfill sync in paused, the global backfill state is updated. I asked @AgeManning about this and he deemed it a bug, so this solves it.

aad397f00a Resolve Rust 1.56 lints and warnings (#2728)
## Issue Addressed

When compiling with Rust 1.56.0 the compiler generates 3 instances of this warning:

```
warning: trailing semicolon in macro used in expression position
   --> common/eth2_network_config/src/lib.rs:181:24
    |
181 |                     })?;
    |                        ^
...
195 |         let deposit_contract_deploy_block = load_from_file!(DEPLOY_BLOCK_FILE);
    |                                             ---------------------------------- in this macro invocation
    |
    = note: `#[warn(semicolon_in_expressions_from_macros)]` on by default
    = warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
    = note: for more information, see issue #79813 <https://github.com/rust-lang/rust/issues/79813>
    = note: this warning originates in the macro `load_from_file` (in Nightly builds, run with -Z macro-backtrace for more info)
```

This warning is completely harmless, but will be visible to users compiling Lighthouse v2.0.1 (or earlier) with Rust 1.56.0 (to be released October 21st). It is **completely safe** to ignore this warning, it's just a superficial change to Rust's syntax.

## Proposed Changes

This PR removes the semi-colon as recommended, and fixes the new Clippy lints from 1.56.0

d2e3d4c6f1 Add flag to disable lock timeouts (#2714)
## Issue Addressed

Mitigates #1096

## Proposed Changes

Add a flag to the beacon node called `--disable-lock-timeouts` which allows opting out of lock timeouts.

The lock timeouts serve a dual purpose:

1. They prevent any single operation from hogging the lock for too long. When a timeout occurs it logs a nasty error which indicates that there's suboptimal lock use occurring, which we can then act on.
2. They allow deadlock detection. We're fairly sure there are no deadlocks left in Lighthouse anymore but the timeout locks offer a safeguard against that.

However, timeouts on locks are not without downsides:

They allow for the possibility of livelock, particularly on slower hardware. If lock timeouts keep failing spuriously the node can be prevented from making any progress, even if it would be able to make progress slowly without the timeout. One particularly concerning scenario which could occur would be if a DoS attack succeeded in slowing block signature verification times across the network, and all Lighthouse nodes got livelocked because they timed out repeatedly. This could also occur on just a subset of nodes (e.g. dual core VPSs or Raspberri Pis).

By making the behaviour runtime configurable this PR allows us to choose the behaviour we want depending on circumstance. I suspect that long term we could make the timeout-free approach the default (#2381 moves in this direction) and just enable the timeouts on our testnet nodes for debugging purposes. This PR conservatively leaves the default as-is so we can gain some more experience before switching the default.

df40700ddd Rename eth2_libp2p to lighthouse_network (#2702)
## Description

The `eth2_libp2p` crate was originally named and designed to incorporate a simple libp2p integration into lighthouse. Since its origins the crates purpose has expanded dramatically. It now houses a lot more sophistication that is specific to lighthouse and no longer just a libp2p integration. 

As of this writing it currently houses the following high-level lighthouse-specific logic:
- Lighthouse's implementation of the eth2 RPC protocol and specific encodings/decodings
- Integration and handling of ENRs with respect to libp2p and eth2
- Lighthouse's discovery logic, its integration with discv5 and logic about searching and handling peers. 
- Lighthouse's peer manager - This is a large module handling various aspects of Lighthouse's network, such as peer scoring, handling pings and metadata, connection maintenance and recording, etc.
- Lighthouse's peer database - This is a collection of information stored for each individual peer which is specific to lighthouse. We store connection state, sync state, last seen ips and scores etc. The data stored for each peer is designed for various elements of the lighthouse code base such as syncing and the http api.
- Gossipsub scoring - This stores a collection of gossipsub 1.1 scoring mechanisms that are continuously analyssed and updated based on the ethereum 2 networks and how Lighthouse performs on these networks.
- Lighthouse specific types for managing gossipsub topics, sync status and ENR fields
- Lighthouse's network HTTP API metrics - A collection of metrics for lighthouse network monitoring
- Lighthouse's custom configuration of all networking protocols, RPC, gossipsub, discovery, identify and libp2p. 

Therefore it makes sense to rename the crate to be more akin to its current purposes, simply that it manages the majority of Lighthouse's network stack. This PR renames this crate to `lighthouse_network`

06e310c4eb Export slashing protection per validator (#2674)
## Issue Addressed

Part of https://github.com/sigp/lighthouse/issues/2557

## Proposed Changes

Refactor the slashing protection export so that it can export data for a subset of validators.

This is the last remaining building block required for supporting the standard validator API (which I'll start to build atop this branch)

## Description

This PR updates the peer connection transition logic. It is acceptable for a peer to immediately transition from a disconnected state to a disconnecting state. This can occur when we are at our peer limit and a new peer's dial us.

cfafe7ba3a Update to consensus-spec-tests v1.1.3 (#2722)
## Issue Addressed

NA

## Proposed Changes

Updates to `testing/ef_tests` to use https://github.com/ethereum/consensus-spec-tests/releases/tag/v1.1.3.

Also updates `initialize_beacon_state_from_eth1` to set the `state.fork.previous_version` to the Altair fork version when starting a new Altair chain from genesis. This will not have an effect on mainnet or any long-lived testnets. This was introduced in https://github.com/ethereum/consensus-specs/releases/tag/v1.1.1.

5cde3fc4da Reduce lock contention in backfill sync (#2716)
## Proposed Changes

Clone the proposer pubkeys during backfill signature verification to reduce the time that the pubkey cache lock is held for. Cloning such a small number of pubkeys has negligible impact on the total running time, but greatly reduces lock contention.

On a Ryzen 5950X, the setup step seems to take around 180us regardless of whether the key is cloned or not, while the verification takes 7ms. When Lighthouse is limited to 10% of one core using `sudo cpulimit --pid <pid> --limit 10` the total time jumps up to 800ms, but the setup step remains only 250us. This means that under heavy load this PR could cut the time the lock is held for from 800ms to 250us, which is a huge saving of 99.97%!

7c23e2142a Allow custom certificates when connecting to BN (#2703)
## Issue Addressed

Resolves #2262 

## Proposed Changes

Add a new CLI flag `--beacon-nodes-tls-certs` which allows the user to specify a path to a certificate file (or a list of files, separated by commas). The VC will then use these certificates (in addition to the existing certificates in the OS trust store) when connecting to a beacon node over HTTPS.

## Additional Info

This only supports certificates in PEM format.

18340d1fb6 Get arbitrary check passing (2.0) (#2710)
## Issue Addressed

NA

## Proposed Changes

This is a wholesale rip-off of #2708, see that PR for more of a description.

I've made this PR since @realbigsean is offline and I can't merge his PR due to Github's frustrating `target-branch-check` bug. I also changed the branch to `unstable`, since I'm trying to minimize the diff between `merge-f2f`/`unstable`. I'll just rebase `merge-f2f` onto `unstable` after this PR merges.

When running `make lint` I noticed the following warning:

```
warning: patch for `fixed-hash` uses the features mechanism. default-features and features will not take effect because the patch dependency does not support this mechanism
```

So, I removed the `features` section from the patch.
