Return state.eth1_data() early if we have passed the transition period post electra. Even if we don't return early, the function would still return state.eth1_data() based on the current conditions. However, doing this explicitly here to match the spec. This covers setting the right eth1_data in our block.
The other thing we need to ensure is that the deposits returned by the eth1_chain is empty post transition.
The only way we get non-empty deposits post the transition is if `state.eth1_deposit_index` in the below code is less than `min(deposit_requests_start_index, state.eth1_data().deposit_count)`.
0850bcfb89/beacon_node/beacon_chain/src/eth1_chain.rs (L543-L579)
This can never happen because state.eth1_deposit_index will be equal to state.eth1_data.deposit count and cannot exceed the value.
@michaelsproul @ethDreamer please double check the logic for deposits being empty post transition. Following the logic in the spec makes my head hurt.

Adds endpoints to add and remove trusted peers from the http api. The added peers are trusted peers so they won't be disconnected for bad scores. We try to maintain a connection to the peer in case they disconnect from us by trying to dial it every heartbeat.
This is a workaround for #7216
In the case of gaps between the in-memory pub key cache and its on-disk representation, use the head state on startup to "top-up" the cache/db w/ any missing validators
Cross builds were failing since:

This seems to have been due to a regression upstream in `ring` which is noted in the v0.17.14 release notes. I'm hoping that updating remedies it.
> Compatibility with GNU binutils 2.29 (used on Amazon Linux 2), and probably even earlier versions, was restored. It is expected that ring 0.17.14 will build on all the systems that 0.17.12 would build on.

Resolves#7091
The `prometheus` crate pulls in `protobuf 2.x` which fails cargo audit. We actually dont use any `protobuf` related features in LH. By disabling default features for `prometheus`, we no longer pull in the `protobuf` crate
This is a backport from `holesky-rescue`.

Original PR to `holesky-rescue`:

Avoid doing database lookups for slots that lie in the hot database when processing status messages. This avoids a DoS vector during non-finality, as loading hot states to iterate block roots is very expensive.
This change makes the `total_difficulty` field in `ExecutionBlock` an `Option<Uint256>` since newer clients are no longer including the `totalDifficulty` field.
I think this will fix https://github.com/sigp/lighthouse/issues/6937 but I was actually more focused on the builder registration case described below.
In our [builder-playground](https://github.com/flashbots/builder-playground) we setup a local devnet using lighthouse, reth, and mev-boost-relay. After upgrading to reth 1.2.0 and lighthouse v7.0.0.beta.0 for Pectra, we noticed that the validator registration process was _sometimes_ failing with:
```
Feb 25 23:35:25.038 ERRO Unable to publish proposer preparation to all beacon nodes, error: Some endpoints failed, num_failed: 1 http://localhost:3500/ => RequestFailed(ServerMessage(ErrorMessage { code: 400, message: "BAD_REQUEST: error updating proposer preparations: ForkchoiceUpdate(EngineError(Api { error: Json(Error(\"missing field `totalDifficulty`\", line: 0, column: 0)) }))", stacktraces: [] })), service: preparation
Feb 25 23:35:25.099 WARN Unable to publish validator registrations to the builder network, error: Some endpoints failed, num_failed: 1 http://localhost:3500/ => RequestFailed(ServerMessage(ErrorMessage { code: 400, message: "BAD_REQUEST: error updating proposer preparations: ForkchoiceUpdate(EngineError(Api { error: Json(Error(\"missing field `totalDifficulty`\", line: 0, column: 0)) }))", stacktraces: [] })), service: preparation
```
What was even more confusing, was that it was sometimes working, which actually led to a wild goose chase thinking it was a networking issue. However, when tracing through the LH code, I came across this comment:
70194dfc6a/beacon_node/beacon_chain/src/beacon_chain.rs (L6048-L6049)
This explained why it sometimes worked, in our playground we run lighthouse with `--prepare-payload-lookahead 8000` thus there was always a 4-second window where the call wasn't made.
But, if the call was made, then this code would 100% fail with updated reth:
https://github.com/sigp/lighthouse/blob/unstable/beacon_node/execution_layer/src/lib.rs#L1688-L1692
Which would then mapped to a `Error::ForkchoiceUpdate` in `update_execution_engine_forkchoice`.
Anyways, the fix was to make `total_difficulty` Optional, and then to update any code paths where it was used. In doing so, I assume that if the EL doesn't include total difficulty then the chain is already post-merge.
Cleaned up and isolated version of the `--disable-attesting` flag for the VC, from the `holesky-rescue` branch:
- https://github.com/sigp/lighthouse/pull/7041
I figured we don't need the `--disable-attesting` flag on the BN for now, and it was a much more invasive impl.
Related to #6880, an issue that's usually observed on local devnets with small number of nodes.
When testing range sync, I usually shutdown a node for some period of time and restart it again. However, if it's within `SYNC_TOLERANCE_EPOCHS` (8), Lighthouse would consider the node as synced, and if it may attempt to produce a block if requested by a validator - on a local devnet, nodes frequently produce blocks - when this happens, the node ends up producing a block that would revert finality and would get disconnected from peers immediately.
NOTE: This is PR#7030 cherry-picked from `unstable` to `release-v7.0.0`.
Run Lighthouse BN with this flag to override:
```
--sync-tolerance--epoch 0
```
Resolves https://github.com/sigp/lighthouse/issues/7000
Set the accept header on builder to the correct value when requesting ssz.
This PR also adds a flag to disable ssz over the builder api altogether. In the case that builders/relays have an ssz bug, we can react quickly by asking clients to restart their nodes with the `--disable-ssz-builder` flag to force json. I'm not fully convinced if this is useful so open to removing it or opening another PR for it.
Testing this currently.

2 changes:
1. Replace Option::map_or(true, ...) with is_none_or(...)
2. Remove unnecessary `Into::into` blocks where the type conversion is apparent from the types
Fix a regression introduced in this PR:
- https://github.com/sigp/lighthouse/pull/6361
We were indexing into the `MerkleTree` with raw generalized indices, which was incorrect and triggering `debug_assert` failures, as described here:
- https://github.com/sigp/lighthouse/issues/7005
- Convert `generalized_index` to the correct leaf index prior to proof generation.
- Add sanity checks on indices used in `BeaconState::generate_proof`.
- Remove debug asserts from `MerkleTree::generate_proof` in favour of actual errors. This would have caught the bug earlier.
- Refactor the EF tests so that the merkle validity tests are actually run. They were misconfigured in a way that resulted in them running silently with 0 test cases, and the `check_all_files_accessed.py` script still had an ignore that covered the test files, so this omission wasn't detected.
Our Holesky nodes running with the light client enabled were logging messages about full queues:
> Feb 12 22:09:28.949 ERRO Work queue is full queue: unknown_light_client_optimistic_update, queue_len: 128, msg: the system has insufficient resources for load, service: bproc
I thought this might be genuine overload, but it turns out this queue was never being read from!
- [x] Rename light-client related queues in the beacon processor for clarity.
- [x] Ensure all light-client related queues are being popped from.
Closes#6983
`GET v2/validator/aggregate_attestation` is not backwards compatible. It only works for post electra attestations. This PR adds backwards compatibility and additional test coverage. We should include this in the upcoming 7.0 beta release if possible
Update spec tests for recent v1.5.0-beta.2 release. There are no substantial changes for Electra and earlier, and the Fulu test updates to be made are tracked here:
- https://github.com/sigp/lighthouse/issues/6957
- Add `SingleAttestation` SSZ tests
- Add new `deposit_with_reorg` fork choice tests
- Update tag to v1.5.0-beta.2
- Ignore Fulu tests
- Re-opened PR from https://github.com/sigp/lighthouse/pull/6869
Writing and running tests I noted that the sync RPC requests are very verbose now.
`DataColumnsByRootRequestId { id: 123, requester: Custody(CustodyId { requester: CustodyRequester(SingleLookupReqId { req_id: 121, lookup_id: 101 }) }) }`
Since this Id is logged rather often I believe there's value in
1. Making them more succinct for log verbosity
2. Make them a string that's easy to copy and work with elastic
Write custom `Display` implementations to render Ids in a more DX format
_ DataColumnsByRootRequestId with a block lookup_
```
123/Custody/121/Lookup/101
```
_DataColumnsByRangeRequestId_
```
123/122/RangeSync/0/5492900659401505034
```
- This one will be shorter after https://github.com/sigp/lighthouse/pull/6868
Also made the logs format and text consistent across all methods
