Closes:
- https://github.com/sigp/lighthouse/issues/7363
- Change default state cache size back to 128.
- Make state pruning properly LRU rather than MSU after skipping the cull-exempt states.
Did not find a specific issue beside https://github.com/sigp/lighthouse/issues/6821
Leverage `whistleblower_reward_quotient_for_state` to have accurate post-electra `proposer_slashings` and `attester_slashings` fields returned by `/eth/v1/beacon/rewards/blocks/<id>`.
#7294
Fix the filtering logic so that we actually filter by committee index for both `Base` and `Electra` attestations.
Added a tiny optimization when calculating committee_index to prevent unneeded memory allocations
Added a regression test
Closes#7167
- Ensure the fork digest is generated from ther light client updates attested header and not the signature slot
- Ensure the format of the SSZ response is spec compliant
- Update the bundled `electra.yaml` preset files for `mainnet` and `minimal` to match `consensus-specs` as of: bf09edef17
- Add the field `max_pending_deposits_per_epoch` to our runtime representation of `ElectraPreset`. This results in it appearing in `/eth/v1/config/spec` where it was previously absent.
Downgrade light client errors to debug
Error messages are alarming and usually indicate somethings wrong with the beacon node. The Light Client service is supposed to minimally impact users, and most will not care if the light client server is erroring. Furthermore, the only errors we've seen in the wild are during hard forks, for the first few epochs before the fork finalizes.
Not essential to merge this now, but I'm going through TODOs for Electra to make sure we haven't missed anything.
Targeting this at the release branch anyway so that auditors/readers don't get alarmed 😅
Resolves#6811
Rename `GOSSIP_MAX_SIZE` to `MAX_PAYLOAD_SIZE` and remove `MAX_CHUNK_SIZE` in accordance with the spec.
The spec also "clarifies" the message size limits at different levels. The rpc limits are equivalent to what we had before imo.
The gossip limits have additional checks.
I have gotten rid of the `is_bellatrix_enabled` checks that used a lower limit (1mb) pre-merge. Since all networks we run start from the merge, I don't think this will break any setups.
N/A
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.
N/A
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

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
