      * paras: `include_pvf_check_statement` rt bench
      
      Resolves #4933
      
      This PR adds a benchmark for the `include_pvf_check_statement`
      dispatchable. This is a necessary step to make it work without
      modifications. That enables us to proceed with testing on Versi.
      
      This introduces 5 new benchmarks. Those measure performance of the
      `include_pvf_check_statement` under 2 different conditions:
      
      1. regular vote submission. That's the common case.
      2. submission of the last vote. That happens only once and leads to a
         heavy finalization stage.
      
      There are 2 different types of finalization (one for onboarding, one for
      upgrading) and there are two outcomes: accepted and rejected. Those 4
      are similar but I decided to cover them all and assign the maximum of
      all 4. This is to avoid a situation when one of those paths becomes more
      heavier than others and opens up an attack venue.
      
      The regular vote submission weight is drastically different from the
      submission last vote weight. That's why in case during runtime
      finalization was not executed the weight consumed value will be lowered
      down to the regular vote submission.
      
      The finalization weight is proportional to the number of "causes", i.e.
      the events that caused the PVF pre-checking vote in the first place, and
      here we assume that the maximum number of causes is 100.
      
      Theoretically, there is nothing that prevents an adversary to
      register/upgrade to more than 100 parachains. In that case, the consumed
      weight will be lower than the actual time consumed by the finalization
      process. That can enable a DoS vector.
      
      However, practically, it is not very possible. Right now it is very
      expensive to call `schedule_para_initialize` because it requires a very
      large lock up of funds. Moreover, finalizing a vote with 100 causes
      leads to around 31ms time spent. Finalizing more will require more time.
      However, finalizing with 200 causes will cause ≈62ms delay. This is not
      that bad since even though we had a full block and the adversary tried
      to finalize 200 causes it won't be able to even exceed the operational
      extrinsic boundary of 250ms and even if so it won't make big difference.
      
      That said, this should be addressed later on, esp. when we enable
      parathreads, which will make creating causes easier. One of potential
      solutions will be shifting the logic of finalization into
      `on_initialize`/`on_finalize`. Another is to create a maximum number of
      causes and then reject upgrades or onboardings if that was reached.

      Then, on top of that, this commit changes the logic of

      paras: do not allow PVF vote submission if disabled (#4684) · 815021ab
      Sergey Pepyakin authored
      if the PVF pre-checking is disabled the runtime dispatchable will reject
      any attempts of submission. This is also concern the unsigned tx
      validation.
      
      Right now, the `include_pvf_check_statement` dispatchable is effectively
      uncallable because of the weight set to the maximum value. If we were to
      benchmark it, it would become includable in a block, but since there
      will be no active votes, the dispatchable won't do anything.
      
      However, it will execute some code, like signature validation and
      querying some storage entries. To be completely safe, we can bail out
      early if the `pvf_checking_enabled` config is disabled. That's what this
      PR does.

      paras: Add runtime events for PVF pre-checking (#4683) · 21419a81
      Sergey Pepyakin authored
      In this PR, paras module emit runtime events on certain PVF pre-checking
      related conditions.
      
      Specifically, there are 3 new events in the paras module:
      
      1. PvfCheckStarted
      2. PvfCheckAccepted
      3. PvfCheckRejected
      
      All of those have identifiers for the parachain that triggered the PVF
      pre-checking and the validation code that goes through the pre-checking.
      
      The mechanics of those are as follows. Each time a new PVF is added, be
      it due to onboarding or upgrading, the `PvfCheckStarted` will be
      triggered. If another parachain triggers a pre-checking process for the
      validation code which is already being pre-checked, another
      `PvfCheckStarted` event will be triggered with the corresponding para
      id.
      
      When the PVF pre-checking voting for a PVF was finished, several
      `PvfCheckAccepted/Rejected` events will be triggered: one for each para id that
      was subscribed to this check (i.e. was a "cause" for it).
      
      If the PVF pre-checking is disabled, then one can still expect these
      events to be fired. Since insta PVF approval is syncronous, the
      `PvfCheckStarted` will be followed by the `PvfCheckAccepted` with the
      same validation code and para id.
      
      If somebody is interested in following validation code changes for a PVF
      of a parachain, they would need to subscribe to those events. I did not
      supply the topics for the events, since I am not sure if that's needed
      or will be used, but they can be added later if needed.

      configuration: Rename validation_upgrade_{frequency -> cooldown} (#4635) · 72a92eaf
      Sergey Pepyakin authored
      This just renames a member of `HostConfiguration` from
      validation_upgrade_frequency to -//-_cooldown.
      
      As was already pointed out in #4460 the existing name is a misnomer, the
      member actually represents a minimum time period between upgrades, which
      is neatly expressed by a word cooldown.
      
      I've been planning this rename already for some time and the term is
      already used in paras module:

      * paras: add governance control dispatchables
      
      Adds a couple of functions for governance control for the paras module
      in the anticipation of PVF pre-checking enabling.
      
      Specifically, this commit adds a function for pre-registering a PVF that
      governance trusts enough. This function will come in handy in case there
      is a parachain that does not follow the GoAhead signal. That is, does
      not include https://github.com/paritytech/cumulus/pull/517.
      
      This may be not an exhaustive list of the functions that may come in
      handy. Any suggestions to add more are welcome.

      pvf-precheck: Integrate PVF pre-checking into paras module (#4457) · 47810dca

      * pvf-precheck: Integrate PVF pre-checking into paras module
      
      Closes #4009
      
      This is the most of the runtime-side change needed for #3211.
      
      Here is how it works.
      
      The PVF pre-checking can be triggered either by an upgrade or by
      onboarding (i.e. calling `schedule_para_initialize`). The PVF
      pre-checking process is identified by the PVF code hash that is being
      voted on. If there is already PVF pre-checking process running, then no
      new PVF pre-checking process will be started. Instead, we just subscribe
      to the existing one.
      
      If there is no PVF pre-checking process running but the PVF code hash
      was already saved in the storage, that necessarily means (I invite the
      reviewers to double-check this invariant) that the PVF already passed
      pre-checking. This is equivalent to instant approving of the PVF.
      
      The pre-checking process can be concluded either by obtaining a
      supermajority or if it expires.
      
      Each validator checks the list of PVFs available for voting. The vote is
      binary, i.e. accept or reject a given PVF. As soon as the supermajority
      of votes are collected for one of the sides of the vote, the voting is
      concluded in that direction and the effects of the voting are enacted.
      
      Only validators from the active set can participate in the vote. The set
      of active validators can change each session. That's why we reset the
      votes each session. A voting that observed a certain number of sessions
      will be rejected.
      
      The effects of the PVF accepting depend on the operations requested it:
      
      1. All onboardings subscribed to the approved PVF pre-checking process will
      get scheduled and after passing 2 session boundaries they will be onboarded.
      2. All upgrades subscribed to the approved PVF pre-checking process will
      get scheduled very similarly to the existing process. Upgrades with
      pre-checking are really the same process that is just delayed by the
      time required for pre-checking voting. In case of instant approval the
      mechanism is exactly the same. This is important from parachains
      compatibility standpoint since following the delayed upgrade requires
      the parachain to implement
      https://github.com/paritytech/cumulus/pull/517.
      
      In case, PVF pre-checking process was concluded with rejection, then all
      the requesting operations get cancelled. For onboarding it means it gets
      without movement: the lifecycle of such parachain is terminated on the
      `Onboarding` state and after rejection the lifecycle is none. That in
      turn means that the caller can attempt registering the parachain once
      more. For upgrading it means that the upgrade process is aborted: that
      flashes go-ahead signal with `Abort` flag.
      
      Rejection leads to removing the allegedly bad validation code from the
      chain storage. Among other things, this implies that the operation can
      be re-requested. That allows for retrying an operation in case there was
      some bug. At the same time it does not look as a DoS vector due to the
      caching performed by the nodes.
      
      PVF pre-checking can be enabled and disabled. Initially, according to
      the changes in #4420, this mechanism is disabled. Triggering the PVF
      pre-checking when it is disabled just means that we insta approve the
      requesting operation. This should lead to the behavior being unchanged.

      pvf-precheck: Strip PastCodeMeta (#4408) · 3c2fb21b
      Sergey Pepyakin authored
      This PR is a part of
      https://github.com/paritytech/polkadot/issues/3211.
      
      This PR prepares ground for the following runtime changes required for
      PVF pre-checking. Specifically, we do several changes here:
      
      1. We remove `validation_code_at` and `validation_code_hash_at`. Those
         functions are not used. They were added in the early days with intent
         to use it later but turned out that we do not need them.
      2. We replace `validation_code_hash_at` with just `current_code_hash`
         for the case of inclusion and candidate checking.
      3. We also replace `last_code_upgrade` with a direct query into
         `FutureCodeHash` and `UpgradeRestrictionSignal`. Those in conjunction
         should replace the logic that was used for allowing/disallowing
         upgrades. This requires special attention of the reviewers.
      4. Then we remove the machinery required to support those queries.
         Specifically the code related to `UseCodeAt`. We do not need it since
         we do not answer the historical queries. However, we still leave all
         the data on-chain. At some point we may clean it up, but that would
         be needed to be done with a dedicated migration which can be done as
         follow-up.
      5. Some now irrelevant tests were removed and/or adapted.

      Impose new restrictions on paras init and cleanup (#4360) · bce0e5ac
      Sergey Pepyakin authored
      * Impose new restrictions on paras init and cleanup
      
      For upcoming PVF pre-checking feature we will need to impose a couple of
      new restrictions for:
      
      - `schedule_para_initialize`.
      - `schedule_para_cleanup`.
      
      Specifically, for the former we do not want to allow registration of
      wasm blob that is empty, i.e. 0 bytes. While that currently already
      does not make a lot of sense, it allows us to simplify the PVF
      pre-checking logic: if this PR is deployed before the following changes
      for PVF prechecking then we can be sure that no paras onboarding have to
      have to go through the PVF pre-checking. In case, we deploy it
      altogether this property will allow us to distingush paras that came in
      before PVF pre-checking.
      
      For `schedule_para_cleanup` we do not want to allow offboarding of paras
      that are undergoing the upgrade process. While this is not a harsh
      restriction this change allows us to avoid making the PVF prechecking
      more complicated than it has to be.
      
      * Add a test for schedule_para_initialize
      
      * Link to `ParaLifecycle::is_stable` in docs.
      
      * `schedule_para_{init,cleanup}` docs
      
      Now they link to their original declarations in the pallet for more
      details.
