      This tiny PR extends the `on_validated_block_announce` log with the bad

      Used to identify if the peerID is malicious by correlating with other
      logs (ie peer-set).
      
      While at it, have removed the `\n` from a multiline log, which did not

      Update benchmarking macros (#3934) · d38f6e67
      PG Herveou authored
      
      
      Current benchmarking macro returns a closure with the captured
      benchmarked code.
      This can cause issues when the benchmarked code has complex lifetime
      requirements.
      
      This PR updates the existing macro by injecting the recording parameter
      and invoking the start / stop method around the benchmarked block
      instead of returning a closure
      
      One other added benefit is that you can write this kind of code now as
      well:
      
      ```rust
      let v;
      #[block]
      { v = func.call(); }
      dbg!(v); // or assert something on v

      Move cumulus zombienet tests to aura & async backing (#3568) · df818d29
      Sebastian Kunert authored
      Cumulus test-parachain node and test runtime were still using relay
      chain consensus and 12s blocktimes. With async backing around the corner
      on the major chains we should switch our tests too.
      
      Also needed to nicely test the changes coming to collators in #3168.
      
      ### Changes Overview
      - Followed the [migration
      guide](https://wiki.polkadot.network/docs/maintain-guides-async-backing)
      for async backing for the cumulus-test-runtime
      - Adjusted the cumulus-test-service to use the correct import-queue,
      lookahead collator etc.
      - The block validation function now uses the Aura Ext Executor so that
      the seal of the block is validated
      - Previous point requires that we seal block before calling into
      `validate_block`, I introduced a helper function for that
      - Test client adjusted to provide a slot to the relay chain proof and
      the aura pre-digest

      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.

      Upgrade `trie-db` from `0.28.0` to `0.29.0` (#3982) · 4e73c0fc
      Facundo Farall authored
      
      
      # Description
      - What does this PR do?
      1. Upgrades `trie-db`'s version to the latest release. This release
      includes, among others, an implementation of `DoubleEndedIterator` for
      the `TrieDB` struct, allowing to iterate both backwards and forwards
      within the leaves of a trie.
      2. Upgrades `trie-bench` to `0.39.0` for compatibility.
      3. Upgrades `criterion` to `0.5.1` for compatibility.
      - Why are these changes needed?
      Besides keeping up with the upgrade of `trie-db`, this specifically adds
      the functionality of iterating back on the leafs of a trie, with
      `sp-trie`. In a project we're currently working on, this comes very
      handy to verify a Merkle proof that is the response to a challenge. The
      challenge is a random hash that (most likely) will not be an existing
      leaf in the trie. So the challenged user, has to provide a Merkle proof
      of the previous and next existing leafs in the trie, that surround the
      random challenged hash.
      
      Without having DoubleEnded iterators, we're forced to iterate until we
      find the first existing leaf, like so:
      ```rust
              // ************* VERIFIER (RUNTIME) *************
              // Verify proof. This generates a partial trie based on the proof and
              // checks that the root hash matches the `expected_root`.
              let (memdb, root) = proof.to_memory_db(Some(&root)).unwrap();
              let trie = TrieDBBuilder::<LayoutV1<RefHasher>>::new(&memdb, &root).build();
      
              // Print all leaf node keys and values.
              println!("\nPrinting leaf nodes of partial tree...");
              for key in trie.key_iter().unwrap() {
                  if key.is_ok() {
                      println!("Leaf node key: {:?}", key.clone().unwrap());
      
                      let val = trie.get(&key.unwrap());
      
                      if val.is_ok() {
                          println!("Leaf node value: {:?}", val.unwrap());
                      } else {
                          println!("Leaf node value: None");
                      }
                  }
              }
      
              println!("RECONSTRUCTED TRIE {:#?}", trie);
      
              // Create an iterator over the leaf nodes.
              let mut iter = trie.iter().unwrap();
      
              // First element with a value should be the previous existing leaf to the challenged hash.
              let mut prev_key = None;
              for element in &mut iter {
                  if element.is_ok() {
                      let (key, _) = element.unwrap();
                      prev_key = Some(key);
                      break;
                  }
              }
              assert!(prev_key.is_some());
      
              // Since hashes are `Vec<u8>` ordered in big-endian, we can compare them directly.
              assert!(prev_key.unwrap() <= challenge_hash.to_vec());
      
              // The next element should exist (meaning there is no other existing leaf between the
              // previous and next leaf) and it should be greater than the challenged hash.
              let next_key = iter.next().unwrap().unwrap().0;
              assert!(next_key >= challenge_hash.to_vec());
      ```
      
      With DoubleEnded iterators, we can avoid that, like this:
      ```rust
              // ************* VERIFIER (RUNTIME) *************
              // Verify proof. This generates a partial trie based on the proof and
              // checks that the root hash matches the `expected_root`.
              let (memdb, root) = proof.to_memory_db(Some(&root)).unwrap();
              let trie = TrieDBBuilder::<LayoutV1<RefHasher>>::new(&memdb, &root).build();
      
              // Print all leaf node keys and values.
              println!("\nPrinting leaf nodes of partial tree...");
              for key in trie.key_iter().unwrap() {
                  if key.is_ok() {
                      println!("Leaf node key: {:?}", key.clone().unwrap());
      
                      let val = trie.get(&key.unwrap());
      
                      if val.is_ok() {
                          println!("Leaf node value: {:?}", val.unwrap());
                      } else {
                          println!("Leaf node value: None");
                      }
                  }
              }
      
              // println!("RECONSTRUCTED TRIE {:#?}", trie);
              println!("\nChallenged key: {:?}", challenge_hash);
      
              // Create an iterator over the leaf nodes.
              let mut double_ended_iter = trie.into_double_ended_iter().unwrap();
      
              // First element with a value should be the previous existing leaf to the challenged hash.
              double_ended_iter.seek(&challenge_hash.to_vec()).unwrap();
              let next_key = double_ended_iter.next_back().unwrap().unwrap().0;
              let prev_key = double_ended_iter.next_back().unwrap().unwrap().0;
      
              // Since hashes are `Vec<u8>` ordered in big-endian, we can compare them directly.
              println!("Prev key: {:?}", prev_key);
              assert!(prev_key <= challenge_hash.to_vec());
      
              println!("Next key: {:?}", next_key);
              assert!(next_key >= challenge_hash.to_vec());
      ```
      - How were these changes implemented and what do they affect?
      All that is needed for this functionality to be exposed is changing the
      version number of `trie-db` in all the `Cargo.toml`s applicable, and
      re-exporting some additional structs from `trie-db` in `sp-trie`.

      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 (`...

      https://github.com/paritytech/polkadot-sdk/pull/1492).
      
      Introduces a new binary crate: `frame-omni-bencher`.  
      It allows to directly benchmark a WASM blob - without needing a node or
      chain spec.
      
      This makes it much easier to generate pallet weights and should allow us
      to remove bloaty code from the node.
      It should work for all FRAME runtimes that dont use 3rd party host calls
      or non `BlakeTwo256` block hashing (basically all polkadot parachains
      should work).
      
      It is 100% backwards compatible with the old CLI args, when the `v1`
      compatibility command is used. This is done to allow for forwards
      compatible addition of new commands.
      
      ### Example (full example in the Rust docs)

      Add best block indicator to informant message + print parent block on import message (#4021) · fdb1dba2
      Sebastian Kunert authored
      Sometimes you need to debug some issues just by the logs and reconstruct
      what happened.
      In these scenarios it would be nice to know if a block was imported as
      best block, and what it parent was.
      So here I propose to change the output of the informant to this:

      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.
      
      Partly Closes: https://github.com/paritytech/polkadot-sdk/issues/3945

      `GenesisConfig` presets for runtime (#2714) · f910a15c
      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.

      ## Basic example showcasing a migration using the MBM framework
      
      This PR has been built on top of
      https://github.com/paritytech/polkadot-sdk/pull/1781 and adds two new
      example crates to the `examples` pallet
      
      ### Changes Made:
      
      Added the `pallet-example-mbm` crate: This crate provides a minimal
      example of a pallet that uses MBM. It showcases a storage migration
      where values are migrated from a `u32` to a `u64`.

      Fix Mermaid diagram rendering (#3875) · 0ef37c75
      Liam Aharon authored
      
      
      Closes https://github.com/paritytech/polkadot-sdk/issues/2977
      
      The issue appears to stem from the `aquamarine` crate failing to render
      diagrams in re-exported crates.
      
      e.g. as raised
      [here](https://github.com/paritytech/polkadot-sdk/issues/2977), diagrams
      would render at `frame_support::traits::Hooks` but not the re-exported
      doc `frame::traits::Hooks`, even if I added `aquamarine` as a `frame`
      crate dependency.
      
      To resolve this, I followed advice in
      https://github.com/mersinvald/aquamarine/issues/20 to instead render
      mermaid diagrams directly using JS by adding an `after-content.js`.

      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
