Serves envelope by range and by root requests. Added PayloadEnvelopeStreamer so that we dont need to alter upstream code when we introduce blinded payload envelopes.

Take 2 of #8390.
Fixes the race condition properly instead of propagating the error. I think this is a better alternative, and doesn't seem to look that bad.
* Lift node id loading or generation from `NetworkService ` startup to the `ClientBuilder`, so that it can be used to compute custody columns for the beacon chain without waiting for Network bootstrap.
I've considered and implemented a few alternatives:
1. passing `node_id` to beacon chain builder and compute columns when creating `CustodyContext`. This approach isn't good for separation of concerns and isn't great for testability
2. passing `ordered_custody_groups` to beacon chain. `CustodyContext` only uses this to compute ordered custody columns, so we might as well lift this logic out, so we don't have to do error handling in `CustodyContext` construction. Less tests to update;.

Anchor currently depends on `lighthouse_network` for a few types and utilities that live within. As we use our own libp2p behaviours, we actually do not use the core logic in that crate. This makes us transitively depend on a bunch of unneeded crates (even a whole separate libp2p if the versions mismatch!)
Move things we require into it's own lightweight crate.

#7815
- removes all existing spans, so some span fields that appear in logs like `service_name` may be lost.
- instruments a few key code paths in the beacon node, starting from **root spans** named below:
* Gossip block and blobs
* `process_gossip_data_column_sidecar`
* `process_gossip_blob`
* `process_gossip_block`
* Rpc block and blobs
* `process_rpc_block`
* `process_rpc_blobs`
* `process_rpc_custody_columns`
* Rpc blocks (range and backfill)
* `process_chain_segment`
* `PendingComponents` lifecycle
* `pending_components`
To test locally:
* Run Grafana and Tempo with https://github.com/sigp/lighthouse-metrics/pull/57
* Run Lighthouse BN with `--telemetry-collector-url http://localhost:4317`
Some captured traces can be found here: https://hackmd.io/@jimmygchen/r1sLOxPPeg
Removing the old spans seem to have reduced the memory usage quite a lot - i think we were using them on long running tasks and too excessively:

This PR fixes a bug where wrong columns could get processed immediately after a CGC increase.
Scenario:
- The node's CGC increased due to additional validators attached to it (lets say from 10 to 11)
- The new CGC is advertised and new subnets are subscribed immediately, however the change won't be effective in the data availability check until the next epoch (See [this](ab0e8870b4/beacon_node/beacon_chain/src/validator_custody.rs (L93-L99))). Data availability checker still only require 10 columns for the current epoch.
- During this time, data columns for the additional custody column (lets say column 11) may arrive via gossip as we're already subscribed to the topic, and it may be incorrectly used to satisfy the existing data availability requirement (10 columns), and result in this additional column (instead of a required one) getting persisted, resulting in database inconsistency.
N/A
During building an enr on startup, we weren't using the value in the custody context.
This was resulting in the enr value getting updated when the cgc updates, the change getting persisted, but getting set back to the default on restart.
This PR takes the value explicitly from the custody context.
Closes#7467.
This PR primarily addresses [the P2P changes](https://github.com/ethereum/EIPs/pull/9840) in [fusaka-devnet-2](https://fusaka-devnet-2.ethpandaops.io/). Specifically:
* [the new `nfd` parameter added to the `ENR`](https://github.com/ethereum/EIPs/pull/9840)
* [the modified `compute_fork_digest()` changes for every BPO fork](https://github.com/ethereum/EIPs/pull/9840)
90% of this PR was absolutely hacked together as fast as possible during the Berlinterop as fast as I could while running between Glamsterdam debates. Luckily, it seems to work. But I was unable to be as careful in avoiding bugs as I usually am. I've cleaned up the things *I remember* wanting to come back and have a closer look at. But still working on this.
Progress:
* [x] get it working on `fusaka-devnet-2`
* [ ] [*optional* disconnect from peers with incorrect `nfd` at the fork boundary](https://github.com/ethereum/consensus-specs/pull/4407) - Can be addressed in a future PR if necessary
* [x] first pass clean-up
* [x] fix up all the broken tests
* [x] final self-review
* [x] more thorough review from people more familiar with affected code
Lighthouse is currently loggign a lot errors in the `RPC` behaviour whenever a response is received for a request_id that no longer exists in active_inbound_requests. This is likely due to a data race or timing issue (e.g., the peer disconnecting before the response is handled).
This PR addresses that by removing the error logging from the RPC layer. Instead, RPC::send_response now simply returns an Err, shifting the responsibility to the main service. The main service can then determine whether the peer is still connected and only log an error if the peer remains connected.
Thanks @ackintosh for helping debug!
Resolves#6767
This PR implements a basic version of validator custody.
- It introduces a new `CustodyContext` object which contains info regarding number of validators attached to a node and the custody count they contribute to the cgc.
- The `CustodyContext` is added in the da_checker and has methods for returning the current cgc and the number of columns to sample at head. Note that the logic for returning the cgc existed previously in the network globals.
- To estimate the number of validators attached, we use the `beacon_committee_subscriptions` endpoint. This might overestimate the number of validators actually publishing attestations from the node in the case of multi BN setups. We could also potentially use the `publish_attestations` endpoint to get a more conservative estimate at a later point.
- Anytime there's a change in the `custody_group_count` due to addition/removal of validators, the custody context should send an event on a broadcast channnel. The only subscriber for the channel exists in the network service which simply subscribes to more subnets. There can be additional subscribers in sync that will start a backfill once the cgc changes.
TODO
- [ ] **NOT REQUIRED:** Currently, the logic only handles an increase in validator count and does not handle a decrease. We should ideally unsubscribe from subnets when the cgc has decreased.
- [ ] **NOT REQUIRED:** Add a service in the `CustodyContext` that emits an event once `MIN_EPOCHS_FOR_BLOB_SIDECARS_REQUESTS ` passes after updating the current cgc. This event should be picked up by a subscriber which updates the enr and metadata.
- [x] Add more tests
Closes https://github.com/sigp/lighthouse/issues/6895
We need sync to retry custody requests when a peer CGC updates. A higher CGC can result in a data column subnet peer count increasing from 0 to 1, allowing requests to happen.
Add new sync event `SyncMessage::UpdatedPeerCgc`. It's sent by the router when a metadata response updates the known CGC
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.
I've been working at updating another library to latest Lighthouse and got very confused with RPC request Ids.
There were types that had fields called `request_id` and `id`. And interchangeably could have types `PeerRequestId`, `rpc::RequestId`, `AppRequestId`, `api_types::RequestId` or even `Request.id`.
I couldn't keep track of which Id was linked to what and what each type meant.
So this PR mainly does a few things:
- Changes the field naming to match the actual type. So any field that has an `AppRequestId` will be named `app_request_id` rather than `id` or `request_id` for example.
- I simplified the types. I removed the two different `RequestId` types (one in Lighthouse_network the other in the rpc) and grouped them into one. It has one downside tho. I had to add a few unreachable lines of code in the beacon processor, which the extra type would prevent, but I feel like it might be worth it. Happy to add an extra type to avoid those few lines.
- I also removed the concept of `PeerRequestId` which sometimes went alongside a `request_id`. There were times were had a `PeerRequest` and a `Request` being returned, both of which contain a `RequestId` so we had redundant information. I've simplified the logic by removing `PeerRequestId` and made a `ResponseId`. I think if you look at the code changes, it simplifies things a bit and removes the redundant extra info.
I think with this PR things are a little bit easier to reasonable about what is going on with all these RPC Ids.
NOTE: I did this with the help of AI, so probably should be checked
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.
I feel it's preferable to do this explicitly by updating the revision on `Cargo.toml` rather than implicitly by letting `Cargo.lock` control the revision of the branch.
We forked `gossipsub` into the lighthouse repo sometime ago so that we could iterate quicker on implementing back pressure and IDONTWANT.
Meanwhile we have pushed all our changes upstream and we are now the main maintainers of `rust-libp2p` this allows us to use upstream `gossipsub` again.
Nonetheless we still use our forked repo to give us freedom to experiment with features before submitting them upstream
NA
Bumps the `ethereum_ssz` version, along with other crates that share the dep.
Primarily, this give us bitfields which can store 128 bytes on the stack before allocating, rather than 32 bytes (https://github.com/sigp/ethereum_ssz/pull/38). The validator count has increase massively since we set it at 32 bytes, so aggregation bitfields (et al) now require a heap allocation. This new value of 128 should get us to ~2m active validators.
Addresses #6854.
PeerDAS requires unsubscribing a Gossip topic at a fork boundary. This is not possible with our current topic machinery.
Instead of defining which topics have to be **added** at a given fork, we define the complete set of topics at a given fork. The new start of the show and key function is:
```rust
pub fn core_topics_to_subscribe<E: EthSpec>(
fork_name: ForkName,
opts: &TopicConfig,
spec: &ChainSpec,
) -> Vec<GossipKind> {
// ...
if fork_name.deneb_enabled() && !fork_name.fulu_enabled() {
// All of deneb blob topics are core topics
for i in 0..spec.blob_sidecar_subnet_count(fork_name) {
topics.push(GossipKind::BlobSidecar(i));
}
}
// ...
}
```
`core_topics_to_subscribe` only returns the blob topics if `fork < Fulu`. Then at the fork boundary, we subscribe with the new fork digest to `core_topics_to_subscribe(next_fork)`, which excludes the blob topics.
I added `is_fork_non_core_topic` to carry on to the next fork the aggregator topics for attestations and sync committee messages. This approach is future-proof if those topics ever become fork-dependent.
Closes https://github.com/sigp/lighthouse/issues/6854
`TODO(das)` now that PeerDAS is scheduled in a hard fork we can subscribe to its topics on the fork activation. In current stable we subscribe to PeerDAS topics as soon as the node starts if PeerDAS is scheduled.
This PR adds another todo to unsubscribe to blob topics at the fork. This other PR included solution for that, but I can include it in a separate PR
- https://github.com/sigp/lighthouse/pull/5899/files
Include PeerDAS topics as part of Fulu fork in `fork_core_topics`.
N/A
In https://github.com/sigp/lighthouse/pull/6329 we changed `max_blobs_per_block` from a preset to a config value.
We weren't using the right value based on fork in that PR. This is a follow up PR to use the fork dependent values.
In the proces, I also updated other places where we weren't using fork dependent values from the ChainSpec.
Note to reviewer: easier to go through by commit
* move main Behaviour to mod.rs for better readibility
and remove connection limits checks after connection has been established,
as those checks have already been done by connection limits Behaviour.
* improve logging wording wrt dial logic
when we call dial_peer we are not yet dialing but just adding the peer to the dial queue
* do not use a constant for MAX_CONNECTIONS_PER_PEER
we only use it at one place, and the function call is explicit.
* address review and re-instate connection limits checks,
but do it before the connection has been established.
* Merge branch 'unstable' of github.com:sigp/lighthouse into remove-dial-error-denied
* Merge branch 'unstable' of github.com:sigp/lighthouse into remove-dial-error-denied
