      Fixes `TotalValueLocked` out of sync in nomination pools (#3052) · aac07af0
      Gonçalo Pestana authored
      The `TotalLockedValue` storage value in nomination pools pallet may get
      out of sync if the staking pallet does implicit withdrawal of unlocking
      chunks belonging to a bonded pool stash. This fix is based on a new
      method in the `OnStakingUpdate` traits, `on_withdraw`, which allows the
      nomination pools pallet to adjust the `TotalLockedValue` every time
      there is an implicit or explicit withdrawal from a bonded pool's stash.
      
      This PR also adds a migration that checks and updates the on-chain TVL
      if it got out of sync due to the bug this PR fixes.
      
      **Changes to `trait OnStakingUpdate`**
      
      In order for staking to notify the nomination pools pallet that chunks
      where withdrew, we add a new method, `on_withdraw` to the
      `OnStakingUpdate` trait. The nomination pools pallet filters the
      withdraws that are related to bonded pool accounts and updates the
      `TotalValueLocked` accordingly.
      
      **Others**
      - Adds try-state checks to the EPM/staking e2e tests
      - Adds tests for auto withdrawing in the context of nomination pools
      
      **To-do**
      - [x] check if we need a migration to fix the current `TotalValueLocked`
      (run try-runtime)
      - [x] migrations to fix the current on-chain TVL value 
      
        **Kusama**:
      ```
      TotalValueLocked: 99.4559 kKSM
      TotalValueLocked (calculated) 99.4559 kKSM
      ```
      
      
      ️ **Westend**:
      ```
      TotalValueLocked: 18.4060 kWND
      TotalValueLocked (calculated) 18.4050 kWND
      ```
      **Polkadot**: TVL not released yet.

      [frame] `#[pallet::composite_enum]` improved variant count handling + removed `pallet_balances`'s `MaxHolds` config (#2657)
      
      I started this investigation/issue based on @liamaharon
      
       question
      [here](https://github.com/paritytech/polkadot-sdk/pull/1801#discussion_r1410452499).
      
      ## Problem
      
      The `pallet_balances` integrity test should correctly detect that the
      runtime has correct distinct `HoldReasons` variant count. I assume the
      same situation exists for RuntimeFreezeReason.
      
      It is not a critical problem, if we set `MaxHolds` with a sufficiently
      large value, everything should be ok. However, in this case, the
      integrity_test check becomes less useful.
      
      **Situation for "any" runtime:**
      - `HoldReason` enums from different pallets:
      ```rust
              /// from pallet_nis
              #[pallet::composite_enum]
      	pub enum HoldReason {
      		NftReceipt,
      	}
      
              /// from pallet_preimage
              #[pallet::composite_enum]
      	pub enum HoldReason {
      		Preimage,
      	}
      
              // from pallet_state-trie-migration
              #[pallet::composite_enum]
      	pub enum HoldReason {
      		SlashForContinueMigrate,
      		SlashForMigrateCustomTop,
      		SlashForMigrateCustomChild,
      	}
      ```
      
      - generated `RuntimeHoldReason` enum looks like:
      ```rust
      pub enum RuntimeHoldReason {
      
          #[codec(index = 32u8)]
          Preimage(pallet_preimage::HoldReason),
      
          #[codec(index = 38u8)]
          Nis(pallet_nis::HoldReason),
      
          #[codec(index = 42u8)]
          StateTrieMigration(pallet_state_trie_migration::HoldReason),
      }
      ```
      
      - composite enum `RuntimeHoldReason` variant count is detected as `3`
      - we set `type MaxHolds = ConstU32<3>`
      - `pallet_balances::integrity_test` is ok with `3`(at least 3)
      
      However, the real problem can occur in a live runtime where some
      functionality might stop working. This is due to a total of 5 distinct
      hold reasons (for pallets with multi-instance support, it is even more),
      and not all of them can be used because of an incorrect `MaxHolds`,
      which is deemed acceptable according to the `integrity_test`:
        ```
        // pseudo-code - if we try to call all of these:
      
      T::Currency::hold(&pallet_nis::HoldReason::NftReceipt.into(),
      &nft_owner, deposit)?;
      T::Currency::hold(&pallet_preimage::HoldReason::Preimage.into(),
      &nft_owner, deposit)?;
      
      T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForContinueMigrate.into(),
      &nft_owner, deposit)?;
      
        // With `type MaxHolds = ConstU32<3>` these two will fail
      
      T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForMigrateCustomTop.into(),
      &nft_owner, deposit)?;
      
      T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForMigrateCustomChild.into(),
      &nft_owner, deposit)?;
        ```  
      
      
      ## Solutions
      
      A macro `#[pallet::*]` expansion is extended of `VariantCount`
      implementation for the `#[pallet::composite_enum]` enum type. This
      expansion generates the `VariantCount` implementation for pallets'
      `HoldReason`, `FreezeReason`, `LockId`, and `SlashReason`. Enum variants
      must be plain enum values without fields to ensure a deterministic
      count.
      
      The composite runtime enum, `RuntimeHoldReason` and
      `RuntimeFreezeReason`, now sets `VariantCount::VARIANT_COUNT` as the sum
      of pallets' enum `VariantCount::VARIANT_COUNT`:
      ```rust
      #[frame_support::pallet(dev_mode)]
      mod module_single_instance {
      
      	#[pallet::composite_enum]
      	pub enum HoldReason {
      		ModuleSingleInstanceReason1,
      		ModuleSingleInstanceReason2,
      	}
      ...
      }
      
      #[frame_support::pallet(dev_mode)]
      mod module_multi_instance {
      
      	#[pallet::composite_enum]
      	pub enum HoldReason<I: 'static = ()> {
      		ModuleMultiInstanceReason1,
      		ModuleMultiInstanceReason2,
      		ModuleMultiInstanceReason3,
      	}
      ...
      }
      
      
      impl self::sp_api_hidden_includes_construct_runtime::hidden_include::traits::VariantCount
          for RuntimeHoldReason
      {
          const VARIANT_COUNT: u32 = 0
              + module_single_instance::HoldReason::VARIANT_COUNT
              + module_multi_instance::HoldReason::<module_multi_instance::Instance1>::VARIANT_COUNT
              + module_multi_instance::HoldReason::<module_multi_instance::Instance2>::VARIANT_COUNT
              + module_multi_instance::HoldReason::<module_multi_instance::Instance3>::VARIANT_COUNT;
      }
      ```
      
      In addition, `MaxHolds` is removed (as suggested
      [here](https://github.com/paritytech/polkadot-sdk/pull/2657#discussion_r1443324573))
      from `pallet_balances`, and its `Holds` are now bounded to
      `RuntimeHoldReason::VARIANT_COUNT`. Therefore, there is no need to let
      the runtime specify `MaxHolds`.
      
      
      ## For reviewers
      
      Relevant changes can be found here:
      - `substrate/frame/support/procedural/src/lib.rs`

      [NPoS] Remove better solution threshold for unsigned submissions (#2694) · ffb2125f
      Ankan authored
      closes https://github.com/paritytech-secops/srlabs_findings/issues/78.
      
      Removes `BetterUnsignedThreshold` from pallet EPM. This will essentially
      mean any solution submitted by the validator that is strictly better
      than the current queued solution would be accepted.
      
      The reason for having these thresholds is to limit number of solutions
      submitted on-chain. However for unsigned submissions, the number of
      solutions that could be submitted on average is limited even without
      thresholding (calculation shown in the corresponding issue).

      Staking: Add `deprecate_controller_batch` AdminOrigin call (#2589) · 048a9c27
      Ross Bulat authored
      
      
      Partially Addresses #2500
      
      Adds a `deprecate_controller_batch` call to the staking pallet that is
      callable by `Root` and `StakingAdmin`. To be used for controller account
      deprecation and removed thereafter. Adds
      `MaxControllersDeprecationBatch` pallet constant that defines max
      possible deprecations per call.
      
      - [x] Add `deprecate_controller_batch` call, and
      `MaxControllersInDeprecationBatch` constant.
      - [x] Add tests, benchmark, weights. Tests that weight is only consumed
      if unique pair.
      - [x] Adds `StakingAdmin` origin to staking's `AdminOrigin` type in
      westend runtime.
      - [x] Determined that worst case 5,900 deprecations does fit into
      `maxBlock` `proofSize` and `refTime` in both normal and operational
      thresholds, meaning we can deprecate all controllers for each network in
      one call.
      
      ## Block Weights
      
      By querying `consts.system.blockWeights` we can see that the
      `deprecate_controller_batch` weights fit within the `normal` threshold
      on Polkadot.
      
      #### `controller_deprecation_batch` where i = 5900:
      #### Ref time: 69,933,325,300
      #### Proof size: 21,040,390
      
      ### Polkadot 
      
      ```
      // consts.query.blockWeights
      
      maxBlock: {
              refTime: 2,000,000,000,000
              proofSize: 18,446,744,073,709,551,615
      }
      normal: {
       maxExtrinsic: {
      	refTime: 1,479,873,955,000
      	proofSize: 13,650,590,614,545,068,195
       }
       maxTotal: {
      	refTime: 1,500,000,000,000
      	proofSize: 13,835,058,055,282,163,711
       }
      }
      ```
      
      ### Kusama
      
      ```
      // consts.query.blockWeights
      
        maxBlock: {
          refTime: 2,000,000,000,000
          proofSize: 18,446,744,073,709,551,615
        }
          normal: {
            maxExtrinsic: {
              refTime: 1,479,875,294,000
              proofSize: 13,650,590,614,545,068,195
            }

      [NPoS] Paging reward payouts in order to scale rewardable nominators (#1189) · 00b85c51
      Ankan authored
      
      
      helps https://github.com/paritytech/polkadot-sdk/issues/439.
      closes https://github.com/paritytech/polkadot-sdk/issues/473.
      
      PR link in the older substrate repository:
      https://github.com/paritytech/substrate/pull/13498.
      
      # Context
      Rewards payout is processed today in a single block and limited to
      `MaxNominatorRewardedPerValidator`. This number is currently 512 on both
      Kusama and Polkadot.
      
      This PR tries to scale the nominators payout to an unlimited count in a
      multi-block fashion. Exposures are stored in pages, with each page
      capped to a certain number (`MaxExposurePageSize`). Starting out, this
      number would be the same as `MaxNominatorRewardedPerValidator`, but
      eventually, this number can be lowered through new runtime upgrades to
      limit the rewardeable nominators per dispatched call instruction.
      
      The changes in the PR are backward compatible.
      
      ## How payouts would work like after this change
      Staking exposes two calls, 1) the existing `payout_stakers` and 2)
      `payout_stakers_by_page`.
      
      ### payout_stakers
      This remains backward compatible with no signature change. If for a
      given era a validator has multiple pages, they can call `payout_stakers`
      multiple times. The pages are executed in an ascending sequence and the
      runtime takes care of preventing double claims.
      
      ### payout_stakers_by_page
      Very similar to `payout_stakers` but also accepts an extra param
      `page_index`. An account can choose to payout rewards only for an
      explicitly passed `page_index`.
      
      **Lets look at an example scenario**
      Given an active validator on Kusama had 1100 nominators,
      `MaxExposurePageSize` set to 512 for Era e. In order to pay out rewards
      to all nominators, the caller would need to call `payout_stakers` 3
      times.
      
      - `payout_stakers(origin, stash, e)` => will pay the first 512
      nominators.
      - `payout_stakers(origin, stash, e)` => will pay the second set of 512
      nominators.
      - `payout_stakers(origin, stash, e)` => will pay the last set of 76
      nominators.
      ...
      - `payout_stakers(origin, stash, e)` => calling it the 4th time would
      return an error `InvalidPage`.
      
      The above calls can also be replaced by `payout_stakers_by_page` and
      passing a `page_index` explicitly.
      
      ## Commission note
      Validator commission is paid out in chunks across all the pages where
      each commission chunk is proportional to the total stake of the current
      page. This implies higher the total stake of a page, higher will be the
      commission. If all the pages of a validator's single era are paid out,
      the sum of commission paid to the validator across all pages should be
      equal to what the commission would have been if we had a non-paged
      exposure.
      
      ### Migration Note
      Strictly speaking, we did not need to bump our storage version since
      there is no migration of storage in this PR. But it is still useful to
      mark a storage upgrade for the following reasons:
      
      - New storage items are introduced in this PR while some older storage
      items are deprecated.
      - For the next `HistoryDepth` eras, the exposure would be incrementally
      migrated to its corresponding paged storage item.
      - Runtimes using staking pallet would strictly need to wait at least
      `HistoryDepth` eras with current upgraded version (14) for the migration
      to complete. At some era `E` such that `E >
      era_at_which_V14_gets_into_effect + HistoryDepth`, we will upgrade to
      version X which will remove the deprecated storage items.
      In other words, it is a strict requirement that E<sub>x</sub> -
      E<sub>14</sub> > `HistoryDepth`, where
      E<sub>x</sub> = Era at which deprecated storages are removed from
      runtime,
      E<sub>14</sub> = Era at which runtime is upgraded to version 14.
      - For Polkadot and Kusama, there is a [tracker
      ticket](https://github.com/paritytech/polkadot-sdk/issues/433) to clean
      up the deprecated storage items.
      
      ### Storage Changes
      
      #### Added
      - ErasStakersOverview
      - ClaimedRewards
      - ErasStakersPaged
      
      #### Deprecated
      The following can be cleaned up after 84 eras which is tracked
      [here](https://github.com/paritytech/polkadot-sdk/issues/433).
      
      - ErasStakers.
      - ErasStakersClipped.
      - StakingLedger.claimed_rewards, renamed to
      StakingLedger.legacy_claimed_rewards.
      
      ### Config Changes
      - Renamed MaxNominatorRewardedPerValidator to MaxExposurePageSize.
      
      ### TODO
      - [x] Tracker ticket for cleaning up the old code after 84 eras.
      - [x] Add companion.
      - [x] Redo benchmarks before merge.
      - [x] Add Changelog for pallet_staking.
      - [x] Pallet should be configurable to enable/disable paged rewards.

      Ensure correct variant count in `Runtime[Hold/Freeze]Reason` (#1900) · 35eb133b

      closes https://github.com/paritytech/polkadot-sdk/issues/1882
      
      ## Breaking Changes
      
      This PR introduces a new item to `pallet_balances::Config`:
      
      ```diff
      trait Config {
      ++    type RuntimeFreezeReasons;
      }
      ```
      
      This value is only used to check it against `type MaxFreeze`. A similar
      check has been added for `MaxHolds` against `RuntimeHoldReasons`, which
      is already given to `pallet_balances`.
      
      In all contexts, you should pass the real `RuntimeFreezeReasons`
      generated by `construct_runtime` to `type RuntimeFreezeReasons`. Passing
      `()` would also work, but it would imply that the runtime uses no
      freezes at all.

      The `xcm` crate was renamed to `staging-xcm` to be able to publish it to
      crates.io as someone as squatted `xcm`. The problem with this rename is
      that the `TypeInfo` includes the crate name which ultimately lands in
      the metadata. The metadata is consumed by downstream users like
      `polkadot-js` or people building on top of `polkadot-js`. These people
      are using the entire `path` to find the type in the type registry. Thus,
      their code would break as the type path would now be [`staging_xcm`,
      `VersionedXcm`] instead of [`xcm`, `VersionedXcm`]. This pull request
      fixes this by renaming the path segment `staging_xcm` to `xcm`.

      Refactor staking ledger (#1484) · 8ee4042c
      Gonçalo Pestana authored
      This PR refactors the staking ledger logic to encapsulate all reads and
      mutations of `Ledger`, `Bonded`, `Payee` and stake locks within the
      `StakingLedger` struct implementation.
      
      With these changes, all the reads and mutations to the `Ledger`, `Payee`
      and `Bonded` storage map should be done through the methods exposed by
      StakingLedger to ensure the data and lock consistency of the operations.
      The new introduced methods that mutate and read Ledger are:
      
      - `ledger.update()`: inserts/updates a staking ledger in storage;
      updates staking locks accordingly (and ledger.bond(), which is synthatic
      sugar for ledger.update())
      - `ledger.kill()`: removes all Bonded and StakingLedger related data for
      a given ledger; updates staking locks accordingly;
      `StakingLedger::get(account)`: queries both the `Bonded` and `Ledger`
      storages and returns a `Option<StakingLedger>`. The pallet impl exposes
      fn ledger(account) as synthatic sugar for `StakingLedger::get(account)`.
      
      Retrieving a ledger with `StakingLedger::get()` can be done by providing
      either a stash or controller account. The input must be wrapped in a
      `StakingAccount` variant (Stash or Controller) which is treated
      accordingly. This simplifies the caller API but will eventually be
      deprecated once we completely get rid of the controller account in
      staking. However, this refactor will help with the work necessary when
      completely removing the controller.
      
      Other goals:
      
      - No logical changes have been introduced in this PR;
      - No breaking changes or updates in wallets required;
      - No new storage items or need to perform storage migrations;
      - Centralise the changes to bonds and ledger updates to simplify the
      OnStakingUpdate updates to the target list (related to
      https://github.com/paritytech/polkadot-sdk/issues/443)
      
      Note: it would be great to prevent or at least raise a warning if
      `Ledger<T>`, `Payee<T>` and `Bonded<T>` storage types are accessed
      outside the `StakingLedger` implementation. This PR should not get
      blocked by that feature, but there's a tracking issue here
      https://github.com/paritytech/polkadot-sdk/issues/149

      Implements a variable deposit base calculation for EPM signed submissions (#1547) · 614aa31b
      Gonçalo Pestana authored
      **Note**: This is a lift-and-shift PR from the old substrate and
      polkadot repos, both PRs have been reviewed and audited
      (https://github.com/paritytech/substrate/pull/13983,
      https://github.com/paritytech/polkadot/pull/7140)
      
      ---
      
      This PR implements a generic `BaseDeposit` calculation for signed
      submissions, based on the size of the submission queue.
      
      It adds a new associated type to EPM's config, `type SignedDepositBase`,
      that implements `Convert<usize, BalanceOf<T>>`, which is used to
      calculate the base deposit for signed submissions based on the size of
      the signed submissions queue.
      
      `struct GeometricDepositBase<Balance, Fixed, Inc>` implements the
      convert trait so that the deposit value increases as a geometric
      progression. The deposit base is calculated by `deposit_base =
      fixed_deposit_base * (1 + increase_factor)^n`, where `n` is the term of
      the progression (i.e. the number of signed submissions in the queue).
      `Fixed` and `Inc` generic params are getters for `Balance` and
      `IncreaseFactor` to compute the geometric progression. If
      `IncreaseFactor = 0`, then the signed deposit is constant and equal to
      `Fixed` regardless of the size of the queue.
      
      ### Runtime configs
      
      In Kusama, the progression with 10% increase without changing the
      current signed fixed deposit is: (term == size of the queue)
      
      Term 1: `1,333,333,332,000`
      Term 2: `1,333,333,332,000 * 1.10 = 1,466,666,665,200`
      Term 3: `1,333,333,332,000 * 1.10^2 = 1,613,333,331,200`
      Term 4: `1,333,333,332,000 * 1.10^3 = 1,774,666,664,320`
      Term 5: `1,333,333,332,000 * 1.10^4 = 1,952,133,330,752`
      Term 6: `1,333,333,332,000 * 1.10^5 = 2,147,346,663,827.20`
      Term 7: `1,333,333,332,000 * 1.10^6 = 2,362,081,330,210.92`
      Term 8: `1,333,333,332,000 * 1.10^7 = 2,598,289,463,231.01`
      Term 9: `1,333,333,332,000 * 1.10^8 = 2,858,118,409,554.11`
      Term 10: `1,333,333,332,000 * 1.10^9 = 3,143,930,250,509.52`
      
      Westend:
      
      Term 1: `2,000,000,000,000`
      Term 2: `2,000,000,000,000 * 1.10 = 2,200,000,000,000`
      Term 3: `2,000,000,000,000 * 1.10^2 = 2,420,000,000,000`
      Term 4: `2,000,000,000,000 * 1.10^3 = 2,662,000,000,000`
      Term 5: `2,000,000,000,000 * 1.10^4 = 2,928,200,000,000`
      Term 6: `2,000,000,000,000 * 1.10^5 = 3,221,020,000,000`
      Term 7: `2,000,000,000,000 * 1.10^6 = 3,543,122,000,000`
      Term 8: `2,000,000,000,000 * 1.10^7 = 3,897,434,200,000`
      Term 9: `2,000,000,000,000 * 1.10^8 = 4,287,177,620,000`
      Term 10: `2,000,000,000,000 * 1.10^9 = 4,715,895,382,000`
      
      and in Polkadot, the deposit increase is disabled in the current state
      of the PR, as the increase factor is 0% -- so nothing changes from the
      current behaviour.

      of 2, which is save for runtimes with up to 4096 storage prefices (eg StorageValue).

      HoldReason: Improve usage (#13869) · 05da6d8e
      Bastian Köcher authored
      
      
      * HoldReason: Improve usage
      
      `HoldReason` was switched recently to use the `composite_enum` attribute that will merge the enums
      from all pallets in the runtime to `RuntimeHoldReason`. `pallet-nis` was still requiring that the
      variant was passed as constant to call `hold`. The proper implementation is to use the `HoldReason`
      from inside the pallet directly when calling `hold`. This is done by adding a `RuntimeHoldReason` as
      type to the `Config` trait and requiring that `Currency` is using the same reason. Besides that the
      pr changes the name `HoldIdentifier` in `pallet_balances::Config` to `RuntimeHoldReason`.
