## Issue Addressed
#2107
## Proposed Change
The peer manager will mark peers as disconnected in the discv5 DHT when they disconnect or dial fails
## Additional Info
Rationale for this particular change is explained in my comment on #2107
## Issue Addressed
Resolves#2094
## Proposed Changes
Fixes scripts for creating local testnets. Adds an option in `lighthouse boot_node` to run with a previously generated enr.
## Issue Addressed
NA
## Proposed Changes
Rust 1.50 has landed 🎉
The shiny new `clippy` peers down upon us mere mortals with disgust. Brutish peasants wrapping our `usize`s in superfluous `Option`s... tsk tsk.
I've performed the goat sacrifice and corrected our evil ways in this PR. Tonight we shall pray that Github Actions bestows the almighty green tick upon us.

## Proposed Changes
- Updates all the dependencies mentioned in #2129, except for web3. They haven't merged their tokio 1.0 update because they are waiting on some dependencies of their own. Since we only use web3 in tests, I think updating it in a separate issue is fine. If they are able to merge soon though, I can update in this PR.
- Updates `tokio_util` to 0.6.2 and `bytes` to 1.0.1.
- We haven't made a discv5 release since merging tokio 1.0 updates so I'm using a commit rather than release atm. **Edit:** I think we should merge an update of `tokio_util` to 0.6.2 into discv5 before this release because it has panic fixes in `DelayQueue` --> PR in discv5: https://github.com/sigp/discv5/pull/58
## Additional Info
tokio 1.0 changes that required some changes in lighthouse:
- `interval.next().await.is_some()` -> `interval.tick().await`
- `sleep` future is now `!Unpin` -> https://github.com/tokio-rs/tokio/issues/3028
- `try_recv` has been temporarily removed from `mpsc` -> https://github.com/tokio-rs/tokio/issues/3350
- stream features have moved to `tokio-stream` and `broadcast::Receiver::into_stream()` has been temporarily removed -> `https://github.com/tokio-rs/tokio/issues/2870
- I've copied over the `BroadcastStream` wrapper from this PR, but can update to use `tokio-stream` once it's merged https://github.com/tokio-rs/tokio/pull/3384

This is a little bit of a tip-of-the-iceberg PR. It houses a lot of code changes in the libp2p dependency.
This needs a bit of thorough testing before merging.
The primary code changes are:
- General libp2p dependency update
- Gossipsub refactor to shift compression into gossipsub providing performance improvements and improved API for handling compression

## Issue Addressed
N/A
## Proposed Changes
Fixes multiple issues related to discovering of subnet peers.
1. Subnet discovery retries after yielding no results
2. Metadata updates if peer send older metadata
3. peerdb stores the peer subscriptions from gossipsub
## Issue Addressed
Following slog's documentation, this should help a bit with string allocations. I left it run for two days and mem usage is lower. This is of course anecdotal, but shouldn't harm anyway
## Proposed Changes
remove `String` creation in logs when possible
## Description
This PR updates Lighthouse to tokio 0.3. It includes a number of dependency updates and some structural changes as to how we create and spawn tasks.
This also brings with it a number of various improvements:
- Discv5 update
- Libp2p update
- Fix for recompilation issues
- Improved UPnP port mapping handling
- Futures dependency update
- Log downgrade to traces for rejecting peers when we've reached our max

## Issue Addressed
NA
## Proposed Changes
Increases the target peers for a subnet, so that subnet queries are executed until we have at least the minimum required peers for a mesh (`MESH_N_LOW`). We keep the limit of `6` target peers for aggregated subnet discovery queries, therefore the size (and the time needed) for a query doesn't change.
## Issue Addressed
#1606
## Proposed Changes
Uses dynamic gossipsub scoring parameters depending on the number of active validators as specified in https://gist.github.com/blacktemplar/5c1862cb3f0e32a1a7fb0b25e79e6e2c.
## Additional Info
Although the parameters got tested on Medalla, extensive testing using simulations on larger networks is still to be done and we expect that we need to change the parameters, although this might only affect constants within the dynamic parameter framework.
## Overview
This updates lighthouse to discovery v5.1
Note: This makes lighthouse's discovery not compatible with any previous version. Lighthouse cannot discover peers or send/receive ENR's from any previous version. This is a breaking change.
This resolves#1605
## Issue Addressed
`node` endpoints in #1434
## Proposed Changes
Implement these:
```
/eth/v1/node/health
/eth/v1/node/peers/{peer_id}
/eth/v1/node/peers
```
- Add an `Option<Enr>` to `PeerInfo`
- Finish implementation of `/eth/v1/node/identity`
## Additional Info
- should update the `peers` endpoints when #1764 is resolved

Which issue # does this PR address?
## Proposed Changes
1. Fixes a bug in the simulator where nodes can't find each other due to 0 udp ports in their enr.
2. Fixes bugs in attestation service where we are unsubscribing from a subnet prematurely.
More testing is needed for attestation service fixes.

Adding UPnP support will help grow the DHT by allowing NAT traversal for peers with UPnP supported routers.
Using IGD library: https://docs.rs/igd/0.10.0/igd/
Adding the the libp2p tcp port and discovery udp port. If this fails it simply logs the attempt and moves on

## Issue Addressed
#629
## Proposed Changes
This removes banned peers from the DHT and informs discovery to block the node_id and the known source IP's associated with this node. It has the capabilities of un banning this peer after a period of time.
This also corrects the logic about banning specific IP addresses. We now use seen_ip addresses from libp2p rather than those sent to us via identify (which also include local addresses).
## Issue Addressed
Closes#1365
## Proposed Changes
Dial peers in the `cached_enrs` who aren't connected, aren't banned and satisfy the subnet predicate before making a subnet discovery query.
## Issue Addressed
#1378
## Proposed Changes
Boot node reuses code from beacon_node to initialize network config. This also enables using the network directory to store/load the enr and the private key.
## Additional Info
Note that before this PR the port cli arguments were off (the argument was named `enr-port` but used as `boot-node-enr-port`).
Therefore as port always the cli port argument was used (for both enr and listening). Now the enr-port argument can be used to overwrite the listening port as the public port others should connect to.
Last but not least note, that this restructuring reuses `ethlibp2p::NetworkConfig` that has many more options than the ones used in the boot node. For example the network config has an own `discv5_config` field that gets never used in the boot node and instead another `Discv5Config` gets created later in the boot node process.

## Proposed Changes
Refactor attestation service to send out requests to find peers for subnets as soon as we get attestation duties.
Earlier, we had much more involved logic to send the discovery requests to the discovery service only 6 slots before the attestation slot. Now that discovery is much smarter with grouped queries, the complexity in attestation service can be reduced considerably.

## Issue Addressed
Resolves#1489
## Proposed Changes
- Change starting metadata seq num to 0 according to the [spec](https://github.com/ethereum/eth2.0-specs/blob/dev/specs/phase0/p2p-interface.md#metadata).
- Remove metadata field from `NetworkGlobals`
- Persist metadata to disk on every update
- Load metadata seq number from disk on restart
- Persist enr to disk on update to ensure enr sequence number increments are persisted as well.
## Additional info
Since we modified starting metadata seq num to 0 from 1, we might still see `Invalid Sequence number provided` like in #1489 from prysm nodes if they have our metadata cached.
## Issue Addressed
#1384
Only catch, as currently implemented, when dialing the multiaddr nodes, there is no way to ask the peer manager if they are already connected or dialing
## Issue Addressed
#1483
## Proposed Changes
Upgrades the log to a critical if a listener fails. We are able to listen on many interfaces so a single instance is not critical. We should however gracefully shutdown the client if we have no listeners, although the client can still function solely on outgoing connections.
For now a critical is raised and I leave #1494 for more sophisticated handling of this.
This also updates discv5 to handle errors of binding to a UDP socket such that lighthouse is now able to handle them.
