Shreds have different workload and traffic pattern from TPU vote and
transaction packets. Some of recent changes to SigVerifyStage are not
suitable or at least optimal for shreds sig-verify; e.g. random discard,
dedup with false positives, discard excess by IP-address, ...
SigVerifier trait is meant to abstract out the distinctions between the
two pipelines, but in practice it has led to more verbose and convoluted
code.
This commit discards SigVerifier implementation for shreds sig-verify
and instead provides a standalone stage for verifying shreds signatures.
With recent patches, window-service recv-window does not do much other
than redirecting packets/shreds to downstream channels.
The commit removes window-service recv-window and instead sends
packets/shreds directly from sigverify to retransmit-stage and
window-service insert thread.
- Forward packets by prioritization in desc order
- Add support of cost-tracking by transaction requested compute units
- Hook up account buckets to forwarder
- Add metrics for forwardable batches count
- Remove redundant invalid packets filtering at end of slot since forwarder will do the same when batch forwardable packets
- Add bench test for forwarding
* Remove UseQuic type
Move to storing the UdpSocket on ConnectionCache and accepting a bool
* Remove use_quic from ConnectionCache constructor
Replace with separate with_udp constructor to force callers to choose
Fully deserializing shreds in window-service before sending them to
retransmit stage adds latency to shreds propagation.
This commit instead channels through the payload and relies on only
partial deserialization of a few required fields: slot, shred-index,
shred-type.
* allow initial hash calc to occur in bg
* validator_initialized -> startup_verification_complete
* add infos for leader and vote
* rework snapshot for startup verification
* change to assert
slot_stats are submitted at a different cadence from the rest of
RetransmitStats. Current code erroneously clears slot_stats before
submitting any metrics.
Shred slot and parent are not verified until window-service where
resources are already wasted to sig-verify and deserialize shreds.
This commit moves above verification to earlier in the pipeline in fetch
stage.
Shreds are dropped in window-service if the slot leader is the node
itself:
https://github.com/solana-labs/solana/blob/cd2878acf/core/src/window_service.rs#L181-L185
However this is done after wasting resources verifying signature on
these shreds, and requires a redundant 2nd lookup of the slot leader.
This commit instead discards such shreds in sigverify stage where we
already know the leader for the slot.
Following commits will skip shreds deserializaton before retransmit, and
so we will only have a ShredId and not a fully deserialized shred to
obtain the shuffling seed from.
