## Issue Addressed
Closes#4751
## Proposed Changes
Prevent `state_root_at_slot` and `block_root_at_slot` from erroring out due to a call to `self.slot()?` that fails before genesis. This fixes pre-genesis queries for:
- block at slot 0
- block by genesis block root
- state at slot 0
- state by genesis state root
- state at `finalized` tag
- state at `justified` tag
## Issue Addressed
#4531
## Proposed Changes
add SSZ support to the following block production endpoints:
GET /eth/v2/validator/blocks/{slot}
GET /eth/v1/validator/blinded_blocks/{slot}
## Additional Info
i updated a few existing tests to use ssz instead of writing completely new tests
## Issue Addressed
#4738
## Proposed Changes
See the above issue for details. Went with option #2 to use the async reqwest client in `Eth2NetworkConfig` and propagate the async-ness.

Fix local testnet to generate keys in the correct folders when `BN_COUNT` and `VC_COUNT` don't match.
The current script place the generated validator keys in validator folders based on the `BN_COUNT` config, e.g. `node_1/validators`, `node_2/validators`..etc. We should be using `VC_COUNT` here instead, otherwise the number of validator clients may not match the number of directories generated, and would result in either:
1. a VC not having any keys (when `BN_COUNT` < `VC_COUNT`)
2. a validator key directory not being used (when `BN_COUNT` > `VC_COUNT`).
There is an issue with the file `scripts/local_testnet/start_local_testnet.sh` - when we use a non-default `$SPEC-PRESET` in `vars.env` it runs into an error:
```
executing: ./setup.sh >> /home/ck/.lighthouse/local-testnet/testnet/setup.log
parse error: Invalid numeric literal at line 1, column 7
```
@jimmygchen found the issue and the updated script includes the flag `--spec $SPEC-PRESET`
## Proposed Changes
This PR adds more logging prior to genesis, particularly on networks that start with execution enabled.
There are new checks using `eth_getBlockByHash/Number` to verify that the genesis state's `latest_execution_payload_header` matches the execution node's genesis block.
The first commit also runs the merge-readiness/Capella-readiness checks prior to genesis. This has two effects:
- Give more information on the execution node's status and its readiness for genesis.
- Prevent the `el_offline` status from being set on `/eth/v1/node/syncing`, which previously caused the VC to complain loudly.
I would like to include this for the Holesky reboot. It would have caught the misconfig that doomed the first Holesky.
## Additional Info
- Geth doesn't serve payload bodies prior to genesis, which is why we use the legacy methods. I haven't checked with other ELs yet.
- Currently this is logging errors with _Capella_ genesis states generated by `ethereum-genesis-generator` because the `withdrawals_root` is not set correctly (it is 0x0). This is not a blocker for Holesky, as it starts from Bellatrix (Pari is investigating).
## Issue Addressed
I went through the code base and look for places where we acquire fork choice locks (after the deadlock bug was found and fixed in #4687), and discovered an instance where we re-acquire a lock immediately after dropping it. This shouldn't cause deadlock like the other issue, but is slightly less efficient.
## Issue Addressed
CI is plagued by `AddrAlreadyInUse` failures, which are caused by race conditions in allocating free ports.
This PR removes all usages of the `unused_port` crate for Lighthouse's HTTP API, in favour of passing `:0` as the listen address. As a result, the listen address isn't known ahead of time and must be read from the listening socket after it binds. This requires tying some self-referential knots, which is a little disruptive, but hopefully doesn't clash too much with Deneb 🤞
There are still a few usages of `unused_tcp4_port` left in cases where we start external processes, like the `watch` Postgres DB, Anvil, Geth, Nethermind, etc. Removing these usages is non-trivial because it's hard to read the port back from an external process after starting it with `--port 0`. We might be able to do something on Linux where we read from `/proc/`, but I'll leave that for future work.
* Implement `SignedBlockContent` decoding and fixed bug in `SignedBlockContent::new`

## Issue Addressed
On a new network a user might require importing validators before waiting until genesis has occurred.
## Proposed Changes
Starts the validator client http api before waiting for genesis

This PR adds QUIC support to Lighthouse. As this is not officially spec'd this will only work between lighthouse <-> lighthouse connections. We attempt a QUIC connection (if the node advertises it) and if it fails we fallback to TCP.
This should be a backwards compatible modification. We want to test this functionality on live networks to observe any improvements in bandwidth/latency.
NOTE: This also removes the websockets transport as I believe no one is really using it. It should be mentioned in our release however.

The current Advanced Networking page references the ["--listen-addresses"](14924dbc95/book/src/advanced_networking.md (L124C8-L124C8)) argument, which does not exist in the beacon node. This PR changes such instances of "--listen-addresses" to "--listen-address".
Additionally, the page mentions using sockets that [both listen to IPv6](14924dbc95/book/src/advanced_networking.md (L151)) in a dual-stack setup? Hence, this PR also changes said line to "using one socket for IPv4 and another socket for IPv6".

## Proposed Changes
New release to replace the cancelled v4.4.0 release.
This release includes the bugfix #4687 which avoids a deadlock that was present in v4.4.0.
## Additional Info
Awaiting testing over the weekend this will be merged Monday September 4th.
## Issue Addressed
Fix a deadlock introduced in #4236 which was caught during the v4.4.0 release testing cycle (with thanks to @paulhauner and `gdb`).
## Proposed Changes
Avoid re-locking the fork choice read lock when querying a state by root in the HTTP API. This avoids a deadlock due to the lock already being held.
## Additional Info
The [RwLock docs](https://docs.rs/lock_api/latest/lock_api/struct.RwLock.html#method.read) explicitly advise against re-locking:
> Note that attempts to recursively acquire a read lock on a RwLock when the current thread already holds one may result in a deadlock.

It's a fairly trivial change all things considered as the preset already exists, so shouldn't be hard to maintain.
It compiles and seems to work, but I'm sure I missed something?

## Issue Addressed
Fix a bug in the storage of the linear block roots array in the freezer DB. Previously this array was always written as part of state storage (or block backfill). With state pruning enabled by #4610, these states were no longer being written and as a result neither were the block roots.
The impact is quite low, we would just log an error when trying to forwards-iterate the block roots, which for validating nodes only happens when they try to look up blocks for peers:
> Aug 25 03:42:36.980 ERRO Missing chunk in forwards iterator chunk index: 49726, service: freezer_db
Any node checkpoint synced off `unstable` is affected and has a corrupt database. If you see the log above, you need to re-sync with the fix. Nodes that haven't checkpoint synced recently should _not_ be corrupted, even if they ran the buggy version.
## Proposed Changes
- Use a `ChunkWriter` to write the block roots when states are not being stored.
- Tweak the usage of `get_latest_restore_point` so that it doesn't return a nonsense value when state pruning is enabled.
- Tweak the guarantee on the block roots array so that block roots are assumed available up to the split slot (exclusive). This is a bit nicer than relying on anything to do with the latest restore point, which is a nonsensical concept when there aren't any restore points.
## Additional Info
I'm looking forward to deleting the chunked vector code for good when we merge tree-states 😁
## Issue Addressed
NA
## Proposed Changes
Add the Holesky network config as per 36e4ff2d51/custom_config_data.
Since the genesis state is ~190MB, I've opted to *not* include it in the binary and instead download it at runtime (see #4564 for context). To download this file we have:
- A hard-coded URL for a SigP-hosted S3 bucket with the Holesky genesis state. Assuming this download works correctly, users will be none the wiser that the state wasn't included in the binary (apart from some additional logs)
- If the user provides a `--checkpoint-sync-url` flag, then LH will download the genesis state from that server rather than our S3 bucket.
- If the user provides a `--genesis-state-url` flag, then LH will download the genesis state from that server regardless of the S3 bucket or `--checkpoint-sync-url` flag.
- Whenever a genesis state is downloaded it is checked against a checksum baked into the binary.
- A genesis state will never be downloaded if it's already included in the binary.
- There is a `--genesis-state-url-timeout` flag to tweak the timeout for downloading the genesis state file.
## Log Output
Example of log output when a state is downloaded:

The genesis state is not present in the binary and there are no known download URLs. Please use --checkpoint-sync-url or --genesis-state-url.
```
## Additional Info
I tested the `--genesis-state-url` flag with all 9 Goerli checkpoint sync servers on https://eth-clients.github.io/checkpoint-sync-endpoints/ and they all worked 🎉
My IDE eagerly formatted some `Cargo.toml`. I've disabled it but I don't see the value in spending time reverting the changes that are already there.
I also added the `GenesisStateBytes` enum to avoid an unnecessary clone on the genesis state bytes baked into the binary. This is not a huge deal on Mainnet, but will become more relevant when testing with big genesis states.
When we do a fresh checkpoint sync we're downloading the genesis state to check the `genesis_validators_root` against the finalised state we receive. This is not *entirely* pointless, since we verify the checksum when we download the genesis state so we are actually guaranteeing that the finalised state is on the same network. There might be a smarter/less-download-y way to go about this, but I've run out of cycles to figure that out. Perhaps we can grab it in the next release?
## Issue Addressed
`web3signer_tests` can sometimes timeout.
## Proposed Changes
Increase the `web3signer_tests` timeout from 20s to 30s
## Additional Info
Previously I believed the consistent CI failures were due to this, but it ended up being something different. See below:
---
The timing of this makes it very likely it is related to the [latest release of `web3-signer`](https://github.com/Consensys/web3signer/releases/tag/23.8.1).
I now believe this is due to an out of date Java runtime on our runners. A newer version of Java became a requirement with the new `web3-signer` release.
However, I was getting timeouts locally, which implies that the margin before timeout is quite small at 20s so bumping it up to 30s could be a good idea regardless.

## Issue Addressed
#4654
## Proposed Changes
Only log error if we're unable to read slot clock after genesis.
I thought about simply down grading the `error` to a `warn`, but feel like it's still unnecessary noise before genesis, and it would be good to retain error log if we're pass genesis. But I'd be ok with just downgrading the log level, too.
## Issue Addressed
Closes#4473 (take 3)
## Proposed Changes
- Send a 202 status code by default for duplicate blocks, instead of 400. This conveys to the caller that the block was published, but makes no guarantees about its validity. Block relays can count this as a success or a failure as they wish.
- For users wanting finer-grained control over which status is returned for duplicates, a flag `--http-duplicate-block-status` can be used to adjust the behaviour. A 400 status can be supplied to restore the old (spec-compliant) behaviour, or a 200 status can be used to silence VCs that warn loudly for non-200 codes (e.g. Lighthouse prior to v4.4.0).
- Update the Lighthouse VC to gracefully handle success codes other than 200. The info message isn't the nicest thing to read, but it covers all bases and isn't a nasty `ERRO`/`CRIT` that will wake anyone up.
## Additional Info
I'm planning to raise a PR to `beacon-APIs` to specify that clients may return 202 for duplicate blocks. Really it would be nice to use some 2xx code that _isn't_ the same as the code for "published but invalid". I think unfortunately there aren't any suitable codes, and maybe the best fit is `409 CONFLICT`. Given that we need to fix this promptly for our release, I think using the 202 code temporarily with configuration strikes a nice compromise.
## Issue Addressed
updates underlying dependencies and removes the ignored `RUSTSEC`'s for `cargo audit`.
Also switches `procinfo` to `procfs` on `eth2` to remove the `nom` warning, `procinfo` is unmaintained see [here](https://github.com/danburkert/procinfo-rs/issues/46).
