      [BEEFY] Return valid signatures when verifying commitment (#4259) · 8dc0b337
      Serban Iorga authored
      Trying to split parts of the
      https://github.com/paritytech/polkadot-sdk/pull/1903 into smaller PRs
      
      For https://github.com/paritytech/polkadot-sdk/pull/1903 it would help
      if `verify_with_validator_set()` returned the list of valid
      authority-signatures pairs, since after the verification we need to send
      them in the equivocation proof.

      chainHead: Report unique hashes for pruned blocks (#3667) · bfbf7f5d
      Alexandru Vasile authored
      
      
      This PR ensures that the reported pruned blocks are unique.
      
      While at it, ensure that the best block event is properly generated when
      the last best block is a fork that will be pruned in the future.
      
      To achieve this, the chainHead keeps a LRU set of reported pruned blocks
      to ensure the following are not reported twice:
      
      ```bash
      	 finalized -> block 1 -> block 2 -> block 3
      	
      	                      -> block 2 -> block 4 -> block 5
      	
      	           -> block 1 -> block 2_f -> block 6 -> block 7 -> block 8
      ```
      
      When block 7 is finalized the branch [block 2; block 3] is reported as
      pruned.
      When block 8 is finalized the branch [block 2; block 4; block 5] should
      be reported as pruned, however block 2 was already reported as pruned at
      the previous step.
      
      This is a side-effect of the pruned blocks being reported at level N -
      1. For example, if all pruned forks would be reported with the first
      encounter (when block 6 is finalized we know that block 3 and block 5
      are stale), we would not need the LRU cache.

      logging(fix): Use the proper log target for logging (#4124) · d1f9fe0a
      Alexandru Vasile authored
      This PR ensures the proper logging target (ie `libp2p_tcp` or `beefy`)
      is displayed.
      
      The issue has been introduced in:
      https://github.com/paritytech/polkadot-sdk/pull/4059, which removes the
      normalized metadata of logs.
      
      From
      [documentation](https://docs.rs/tracing-log/latest/tracing_log/trait.NormalizeEvent.html#tymethod.normalized_metadata):
      
      > In tracing-log, an Event produced by a log (through
      [AsTrace](https://docs.rs/tracing-log/latest/tracing_log/trait.AsTrace.html))
      has an hard coded “log” target
      
      >
      [normalized_metadata](https://docs.rs/tracing-log/latest/tracing_log/trait.NormalizeEvent.html#tymethod.normalized_metadata):
      If this Event comes from a log, this method provides a new normalized
      Metadata which has all available attributes from the original log,
      including file, line, module_path and target
      
      This has low implications if a version was deployed containing the
      mentioned pull request, as we'll lose the ability to distinguish between
      log targets.

      Prevent accidental change of network-key for active authorities (#3852) · 2bc4ed11
      Alexandru Gheorghe authored
      
      
      As discovered during investigation of
      https://github.com/paritytech/polkadot-sdk/issues/3314 and
      https://github.com/paritytech/polkadot-sdk/issues/3673 there are active
      validators which accidentally might change their network key during
      restart, that's not a safe operation when you are in the active set
      because of distributed nature of DHT, so the old records would still
      exist in the network until they expire 36h, so unless they have a good
      reason validators should avoid changing their key when they restart
      their nodes.
      
      There is an effort in parallel to improve this situation
      https://github.com/paritytech/polkadot-sdk/pull/3786, but those changes
      are way more intrusive and will need more rigorous testing, additionally
      they will reduce the time to less than 36h, but the propagation won't be
      instant anyway, so not changing your network during restart should be
      the safest way to run your node, unless you have a really good reason to
      change it.
      
      ## Proposal
      1. Do not auto-generate the network if the network file does not exist
      in the provided path. Nodes where the key file does not exist will get
      the following error:
      ```
      Error: 
         0: Starting an authorithy without network key in /home/alexggh/.local/share/polkadot/chains/ksmcc3/network/secret_ed25519.
            
             This is not a safe operation because the old identity still lives in the dht for 36 hours.
            
             Because of it your node might suffer from not being properly connected to other nodes for validation purposes.
            
             If it is the first time running your node you could use one of the following methods.
            
             1. Pass --unsafe-force-node-key-generation and make sure you remove it for subsequent node restarts
            
             2. Separetly generate the key with: polkadot key generate-node-key --file <YOUR_PATH_TO_NODE_KEY>
      ```
      
      2. Add an explicit parameters for nodes that do want to change their
      network despite the warnings or if they run the node for the first time.
      `--unsafe-force-node-key-generation`
      
      3. For `polkadot key generate-node-key` add two new mutually exclusive
      parameters `base_path` and `default_base_path` to help with the key
      generation in the same path the polkadot main command would expect it.
       
      4. Modify the installation scripts to auto-generate a key in default
      path if one was not present already there, this should help with making
      the executable work out of the box after an instalation.
      
      ## Notes
      
      Nodes that do not have already the key persisted will fail to start
      after this change, however I do consider that better than the current
      situation where they start but they silently hide that they might not be
      properly connected to their peers.
      
      ## TODO
      - [x] Make sure only nodes that are authorities on producation chains
      will be affected by this restrictions.
      - [x] Proper PRDOC, to make sure node operators are aware this is
      coming.

      1. The `CustomFmtContext::ContextWithFormatFields` enum arm isn't
      actually used and thus we don't need the enum anymore.
      
      2. We don't do anything with most of the normalized metadata that's
      created by calling `event.normalized_metadata();` - the `target` we can
      get from `event.metadata.target()` and level we can get from
      `event.metadata.level()` - let's just call them direct to simplify
      things. (`event.metadata()` is just a field call under the hood)
      
      Changelog: No functional changes, might run a tad faster with lots of
      logging turned on.

      rpc-v2/transaction: Generate `Invalid` events and add tests (#3784) · 598e9557
      Alexandru Vasile authored
      
      
      This PR ensures that the transaction API generates an `Invalid` events
      for transaction bytes that fail to decode.
      
      The spec mentioned the `Invalid` event at the jsonrpc error section,
      however this spec PR makes things clearer:
      - https://github.com/paritytech/json-rpc-interface-spec/pull/146
      
      While at it have discovered an inconsistency with the generated events.
      The drop event from the transaction pool was incorrectly mapped to the
      `invalid` event.
      
      Added tests for the API stabilize the API soon:

      Detect closed notification substreams instead of evicting all peers (#3983) · a26d25d5
      Dmitry Markin authored
      
      
      This PR brings the fix
      https://github.com/paritytech/substrate/pull/13396 to polkadot-sdk.
      
      In the past, due to insufficient inbound slot count on polkadot &
      kusama, this fix led to low peer count. The situation has improved since
      then after changing the default ratio between `--in-peers` &
      `--out-peers`.
      
      Nevertheless, it's expected that the reported total peer count with this
      fix is going to be lower than without it. This should be seen as the
      correct number of working connections reported, as opposed to also
      reporting already closed connections, and not as lower count of working
      connections with peers.
      
      This PR also removes the peer eviction mechanism, as closed substream
      detection is a more granular way of detecting peers that stopped syncing
      with us.
      
      The burn-in has been already performed as part of testing these changes
      in https://github.com/paritytech/polkadot-sdk/pull/3426.

      peer_store: Increase peer ban time until escapes banned threshold (#4031) · b1c9209a
      Alexandru Vasile authored
      
      
      This is a tiny PR to increase the time a peer remains banned.
      
      A peer is banned when the reputation drops below a threshold.
      With every second, the peer reputation is exponentially decayed towards
      zero.
      
      For the previous setup:
      - decaying to zero from (i32::MAX or i32::MIN) would take 948 seconds
      (15mins 48seconds)
      - from i32::MIN to escaping the banned threshold would take 10 seconds
      This means we are decaying reputation a bit too aggressive and
      misbehaving peers can misbehave again in 10 seconds.
      Another side effect of this is that we have encountered multiple
      warnings caused by a few misbehaving peers.
      
      In the new setup:
      - decaying to zero from (i32::MAX or i32::MIN) would take 3544 seconds
      (59 minutes)
      - from i32::MIN to escaping the banned threshold would take ~69 seconds
      
      This is a followup of:
      - https://github.com/paritytech/polkadot-sdk/pull/4000.
      
      ### Testing Done
      - Created a misbehaving client with
      [subp2p-explorer](https://github.com/lexnv/subp2p-explorer), the client
      is banned for approx 69seconds until it is allowed to connect again.

      Integrate litep2p into Polkadot SDK (#2944) · 80616f6d
      Aaro Altonen authored
      [litep2p](https://github.com/altonen/litep2p) is a libp2p-compatible P2P
      networking library. It supports all of the features of `rust-libp2p`
      that are currently being utilized by Polkadot SDK.
      
      Compared to `rust-libp2p`, `litep2p` has a quite different architecture
      which is why the new `litep2p` network backend is only able to use a
      little of the existing code in `sc-network`. The design has been mainly
      influenced by how we'd wish to structure our networking-related code in
      Polkadot SDK: independent higher-levels protocols directly communicating
      with the network over links that support bidirectional backpressure. A
      good example would be `NotificationHandle`/`RequestResponseHandle`
      abstractions which allow, e.g., `SyncingEngine` to directly communicate
      with peers to announce/request blocks.
      
      I've tried running `polkadot --network-backend litep2p` with a few
      different peer configurations and there is a noticeable reduction in
      networking CPU usage. For high load (`...

      Sometimes you need to debug some issues just by the logs and reconstruct

      In these scenarios it would be nice to know if a block was imported as

      sc-beefy-consensus: Remove unneeded stream. (#4015) · c1063a53
      Bastian Köcher authored
      The stream was just used to communicate from the validator the peer
      reports back to the gossip engine. Internally the gossip engine just
      forwards these reports to the networking engine. So, we can just do this
      directly.
      
      The reporting stream was also pumped [in the worker behind the
      engine](https://github.com/paritytech/polkadot-sdk/blob/9d626189/substrate/client/consensus/beefy/src/worker.rs#L939).
      This means if there was a lot of data incoming over the engine, the
      reporting stream was almost never processed and thus, it could have
      started to grow and we have seen issues around this.

      Michal Kucharczyk authored
      The runtime now can provide a number of predefined presets of
      `RuntimeGenesisConfig` struct. This presets are intended to be used in
      different deployments, e.g.: `local`, `staging`, etc, and should be
      included into the corresponding chain-specs.
      
      Having `GenesisConfig` presets in runtime allows to fully decouple node
      from runtime types (the problem is described in #1984).
      
      **Summary of changes:**
      - The `GenesisBuilder` API was adjusted to enable this functionality
      (and provide better naming - #150):
         ```rust
          fn preset_names() -> Vec<PresetId>;
      fn get_preset(id: Option<PresetId>) -> Option<serde_json::Value>;
      //`None` means default
          fn build_state(value: serde_json::Value);
          pub struct PresetId(Vec<u8>);
         ```
      
      - **Breaking change**: Old `create_default_config` method was removed,
      `build_config` was renamed to `build_state`. As a consequence a node
      won't be able to interact with genesis config for older runtimes. The
      cleanup was made for sake of API simplicity. Also IMO maintaining
      compatibility with old API is not so crucial.
      - Reference implementation was provided for `substrate-test-runtime` and
      `rococo` runtimes. For rococo new
      [`genesis_configs_presets`](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/polkadot/runtime/rococo/src/genesis_config_presets.rs#L530)
      module was added and is used in `GenesisBuilder`
      [_presets-related_](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/polkadot/runtime/rococo/src/lib.rs#L2462-L2485)
      methods.
      
      - The `chain-spec-builder` util was also improved and allows to
      ([_doc_](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/substrate/bin/utils/chain-spec-builder/src/lib.rs#L19)):
         - list presets provided by given runtime (`list-presets`),
      - display preset or default config provided by the runtime
      (`display-preset`),
         - build chain-spec using named preset (`create ... named-preset`),
      
      
      - The `ChainSpecBuilder` is extended with
      [`with_genesis_config_preset_name`](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/substrate/client/chain-spec/src/chain_spec.rs#L447)
      method which allows to build chain-spec using named preset provided by
      the runtime. Sample usage on the node side
      [here](https://github.com/paritytech/polkadot-sdk/blob/2caffaae
      
      /polkadot/node/service/src/chain_spec.rs#L404).
      
      Implementation of #1984.

      chainHead: Ensure reasonable distance between leaf and finalized block (#3562) · 287b116c
      Alexandru Vasile authored
      
      
      This PR ensure that the distance between any leaf and the finalized
      block is within a reasonable distance.
      
      For a new subscription, the chainHead has to provide all blocks between
      the leaves of the chain and the finalized block.
       When the distance between a leaf and the finalized block is large:
       - The tree route is costly to compute
       - We could deliver an unbounded number of blocks (potentially millions)
      (For more details see
      https://github.com/paritytech/polkadot-sdk/pull/3445#discussion_r1507210283)
      
      The configuration of the ChainHead is extended with:
      - suspend on lagging distance: When the distance between any leaf and
      the finalized block is greater than this number, the subscriptions are
      suspended for a given duration.
      - All active subscriptions are terminated with the `Stop` event, all
      blocks are unpinned and data discarded.
      - For incoming subscriptions, until the suspended period expires the
      subscriptions will immediately receive the `Stop` event.
          - Defaults to 128 blocks
      - suspended duration: The amount of time for which subscriptions are
      suspended
          - Defaults to 30 seconds

      chainHead: Allow methods to be called from within a single connection context and limit connections (#3481)
      
      This PR ensures that the chainHead RPC class can be called only from
      within the same connection context.
      
      The chainHead methods are now registered as raw methods. 
      - https://github.com/paritytech/jsonrpsee/pull/1297
      The concept of raw methods is introduced in jsonrpsee, which is an async
      method that exposes the connection ID:
      The raw method doesn't have the concept of a blocking method. Previously
      blocking methods are now spawning a blocking task to handle their
      blocking (ie DB) access. We spawn the same number of tasks as before,
      however we do that explicitly.
      
      Another approach would be implementing a RPC middleware that captures
      and decodes the method parameters:
      - https://github.com/paritytech/polkadot-sdk/pull/3343
      However, that approach is prone to errors since the methods are
      hardcoded by name. Performace is affected by the double deserialization
      that needs to happen to extract the subscription ID we'd like to limit.
      Once from the middleware, and once from the methods itself.
      
      This PR paves the way to implement the chainHead connection limiter:
      - https://github.com/paritytech/polkadot-sdk/issues/1505
      Registering tokens (subscription ID / operation ID) on the
      `RpcConnections` could be extended to return an error when the maximum
      number of operations is reached.
      
      While at it, have added an integration-test to ensure that chainHead
      methods can be called from within the same connection context.
      
      Before this is merged, a new JsonRPC release should be made to expose
      the `raw-methods`:
      - [x] Use jsonrpsee from crates io (blocked by:
      https://github.com/paritytech/jsonrpsee/pull/1297)

      Update derive syn parse 0.2.0 (+ docify) (#3920) · 9a62de27
      Sam Johnson authored
      
      
      derive-syn-parse v0.2.0 came out recently which (finally) adds support
      for syn 2x.
      
      Upgrading to this will remove many of the places where syn 1x was still
      compiling alongside syn 2x in the polkadot-sdk workspace.
      
      This also upgrades `docify` to 0.2.8 which is the version that upgrades
      derive-syn-pasre to 0.2.0.
      
      Additionally, this consolidates the `docify` versions in the repo to all
      use the latest, and in one case upgrades to the 0.2x syntax where 0.1.x
      was still being used.

      authority-discovery: Set intervals to start when authority keys changes (#3764) · 5ac32ee2
      Alexandru Vasile authored
      The authority-discovery mechanism has implemented a few exponential
      timers for:
      - publishing the authority records
      - goes from 2 seconds (when freshly booted) to 1 hour if the node is
      long-running
        - set to 1 hour after successfully publishing the authority record
      - discovering other authority records
      - goes from 2 seconds (when freshly booted) to 10 minutes if the node is
      long-running
      
      This PR resets the exponential publishing and discovery interval to
      defaults ensuring that long-running nodes:
      - will retry publishing the authority records as aggressively as freshly
      booted nodes
      - Currently, if a long-running node fails to publish the DHT record when
      the keys change (ie DhtEvent::ValuePutFailed), it will only retry after
      1 hour
      - will rediscover other authorities faster (since there is a chance that
      other authority keys changed)
      
      The subp2p-explorer has difficulties discovering the authorities when
      the authority set changes in the first few hours. This might be entirely
      due to the recursive nature of the DHT and the needed time to propagate
      the records. However, there is a small chance that the authority
      publishing failed and is only retried in 1h.
      
      Let me know if this makes sense 🙏

      ~~**Note:** In some places the term `Receival` is used to refer to
      message reception, IMO `Reception` is the correct word here, but I left
      it as it is.~~
      
      ~~**Note:** In some places the term `Overlayed` is used instead of the
      more acceptable version `Overlaid` but I also left it as it is.~~
      
      ~~**Note:** In some places the term `Applyable` is used instead of the
      correct version `Applicable` but I also left it as it is.~~
      
      **Note:** Some usage of British vs American english e.g. `judgement` vs
      `judgment`, `initialise` vs `initialize`, `optimise` vs `optimize` etc.
      are both present in different places, but I suppose that's
      understandable given the number of contributors.
      
      ~~**Note:** There is a spelling mistake in `.github/CODEOWNERS` but it
      triggers errors in CI when I make changes to it, so I left it as it
      is.~~

      Implement crypto byte array newtypes in term of a shared type (#3684) · 1e9fd237
      Davide Galassi authored
      Introduces `CryptoBytes` type defined as:
      
      ```rust
      pub struct CryptoBytes<const N: usize, Tag = ()>(pub [u8; N], PhantomData<fn() -> Tag>);
      ```
      
      The type implements a bunch of methods and traits which are typically
      expected from a byte array newtype
      (NOTE: some of the methods and trait implementations IMO are a bit
      redundant, but I decided to maintain them all to not change too much
      stuff in this PR)
      
      It also introduces two (generic) typical consumers of `CryptoBytes`:
      `PublicBytes` and `SignatureBytes`.
      
      ```rust
      pub struct PublicTag;
      pub PublicBytes<const N: usize, CryptoTag> = CryptoBytes<N, (PublicTag, CryptoTag)>;
      
      pub struct SignatureTag;
      pub SignatureBytes<const N: usize, CryptoTag> = CryptoBytes<N, (SignatureTag, CryptoTag)>;
      ```
      
      Both of them use a tag to differentiate the two types at a higher level.
      Downstream specializations will further specialize using a dedicated
      crypto tag. For example in ECDSA:
      
      
      ```rust
      pub struct EcdsaTag;
      
      pub type Public = PublicBytes<PUBLIC_KEY_SERIALIZED_SIZE, EcdsaTag>;
      pub type Signature = PublicBytes<PUBLIC_KEY_SERIALIZED_SIZE, EcdsaTag>;
      ```
      
      Overall we have a cleaner and most importantly **consistent** code for
      all the types involved
      
      All these details are opaque to the end user which can use `Public` and
      `Signature` for the cryptos as before

      rpc: Enable `transaction_unstable_broadcast` RPC V2 API (#3713) · 923f27cc
      Alexandru Vasile authored
      
      
      This PR enables the `transaction_unstable_broadcast ` and
      `transaction_unstable_stop` RPC API.
      
      Since the API is unstable, we don't need to expose this in the release
      notes.
      
      After merging this, we could validate the API in subxt and stabilize it.
      
      Spec PR that stabilizes the API:
