This PR introduces `BlockHashProvider` into `pallet_mmr::Config`
This type is used to get `block_hash` for a given `block_number` rather
than directly using `frame_system::Pallet::block_hash`
The `DefaultBlockHashProvider` uses `frame_system::Pallet::block_hash`
to get the `block_hash`
Closes: #4062
This PR mainly removes `xcm::v3` stuff from `assets-common` to make it
more generic and facilitate the transition to newer XCM versions. Some
of the implementations here used hard-coded `xcm::v3::Location`, but now
it's up to the runtime to configure according to its needs.
Additional/consequent changes:
- `penpal` runtime uses now `xcm::latest::Location` for `pallet_assets`
as `AssetId`, because we don't care about migrations here
- it pretty much simplify xcm-emulator integration tests, where we don't
need now a lots of boilerplate conversions:
```
v3::Location::try_from(...).expect("conversion works")`
```
- xcm-emulator tests
- split macro `impl_assets_helpers_for_parachain` to the
`impl_assets_helpers_for_parachain` and
`impl_foreign_assets_helpers_for_parachain` (avoids using hard-coded
`xcm::v3::Location`)
# Description
Add `transfer_assets_using()` for transferring assets from local chain
to destination chain using explicit XCM transfer types such as:
- `TransferType::LocalReserve`: transfer assets to sovereign account of
destination chain and forward a notification XCM to `dest` to mint and
deposit reserve-based assets to `beneficiary`.
- `TransferType::DestinationReserve`: burn local assets and forward a
notification to `dest` chain to withdraw the reserve assets from this
chain's sovereign account and deposit them to `beneficiary`.
- `TransferType::RemoteReserve(reserve)`: burn local assets, forward XCM
to `reserve` chain to move reserves from this chain's SA to `dest`
chain's SA, and forward another XCM to `dest` to mint and deposit
reserve-based assets to `beneficiary`. Typically the remote `reserve` is
Asset Hub.
- `TransferType::Teleport`: burn local assets and forward XCM to `dest`
chain to mint/teleport assets and deposit them to `beneficiary`.
By default, an asset's reserve is its origin chain. But sometimes we may
want to explicitly use another chain as reserve (as long as allowed by
runtime `IsReserve` filter).
This is very helpful for transferring assets with multiple configured
reserves (such as Asset Hub ForeignAssets), when the transfer strictly
depends on the used reserve.
E.g. For transferring Foreign Assets over a bridge, Asset Hub must be
used as the reserve location.
# Example usage scenarios
## Transfer bridged ethereum ERC20-tokenX between ecosystem parachains.
ERC20-tokenX is registered on AssetHub as a ForeignAsset by the
Polkadot<>Ethereum bridge (Snowbridge). Its asset_id is something like
`(parents:2, (GlobalConsensus(Ethereum), Address(tokenX_contract)))`.
Its _original_ reserve is Ethereum (only we can't use Ethereum as a
reserve in local transfers); but, since tokenX is also registered on
AssetHub as a ForeignAsset, we can use AssetHub as a reserve.
With this PR we can transfer tokenX from ParaA to ParaB while using
AssetHub as a reserve.
## Transfer AssetHub ForeignAssets between parachains
AssetA created on ParaA but also registered as foreign asset on Asset
Hub. Can use AssetHub as a reserve.
And all of the above can be done while still controlling transfer type
for `fees` so mixing assets in same transfer is supported.
# Tests
Added integration tests for showcasing:
- transferring local (not bridged) assets from parachain over bridge
using local Asset Hub reserve,
- transferring foreign assets from parachain to Asset Hub,
- transferring foreign assets from Asset Hub to parachain,
- transferring foreign assets from parachain to parachain using local
Asset Hub reserve.

Implements the idea from
https://github.com/paritytech/polkadot-sdk/pull/3899
- Removed latencies
- Number of runs reduced from 50 to 5, according to local runs it's
quite enough
- Network message is always sent in a spawned task, even if latency is
zero. Without it, CPU time sometimes spikes.
- Removed the `testnet` profile because we probably don't need that
debug additions.
After the local tests I can't say that it brings a significant
improvement in the stability of the results. However, I belive it is
worth trying and looking at the results over time.
This tiny PR extends the `on_validated_block_announce` log with the bad
PeerID.
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
play well with

[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 (`--out-peers 200`), networking CPU
usage goes down from ~110% to ~30% (80 pp) and for normal load
(`--out-peers 40`), the usage goes down from ~55% to ~18% (37 pp).
These should not be taken as final numbers because:
a) there are still some low-hanging optimization fruits, such as
enabling [receive window
auto-tuning](https://github.com/libp2p/rust-yamux/pull/176), integrating
`Peerset` more closely with `litep2p` or improving memory usage of the
WebSocket transport
b) fixing bugs/instabilities that incorrectly cause `litep2p` to do less
work will increase the networking CPU usage
c) verification in a more diverse set of tests/conditions is needed
Nevertheless, these numbers should give an early estimate for CPU usage
of the new networking backend.
This PR consists of three separate changes:
* introduce a generic `PeerId` (wrapper around `Multihash`) so that we
don't have use `NetworkService::PeerId` in every part of the code that
uses a `PeerId`
* introduce `NetworkBackend` trait, implement it for the libp2p network
stack and make Polkadot SDK generic over `NetworkBackend`
* implement `NetworkBackend` for litep2p
The new library should be considered experimental which is why
`rust-libp2p` will remain as the default option for the time being. This
PR currently depends on the master branch of `litep2p` but I'll cut a
new release for the library once all review comments have been
addresses.

This MR contains two major changes and some maintenance cleanup.
## 1. Free Standing Pallet Benchmark Runner
Closes https://github.com/paritytech/polkadot-sdk/issues/3045, depends
on your runtime exposing the `GenesisBuilderApi` (like
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)
Installing the CLI:
```sh
cargo install --locked --path substrate/utils/frame/omni-bencher
frame-omni-bencher --help
```
Building the Westend runtime:
```sh
cargo build -p westend-runtime --release --features runtime-benchmarks
```
Benchmarking the runtime:
```sh
frame-omni-bencher v1 benchmark pallet --runtime target/release/wbuild/westend-runtime/westend_runtime.compact.compressed.wasm --all
```
## 2. Building the Benchmark Genesis State in the Runtime
Closes https://github.com/paritytech/polkadot-sdk/issues/2664
This adds `--runtime` and `--genesis-builder=none|runtime|spec`
arguments to the `benchmark pallet` command to make it possible to
generate the genesis storage by the runtime. This can be used with both
the node and the freestanding benchmark runners. It utilizes the new
`GenesisBuilder` RA and depends on having
https://github.com/paritytech/polkadot-sdk/pull/3412 deployed.
## 3. Simpler args for `PalletCmd::run`
You can do three things here to integrate the changes into your node:
- nothing: old code keeps working as before but emits a deprecated
warning
- delete: remove the pallet benchmarking code from your node and use the
omni-bencher instead
- patch: apply the patch below and keep using as currently. This emits a
deprecated warning at runtime, since it uses the old way to generate a
genesis state, but is the smallest change.
```patch
runner.sync_run(|config| cmd
- .run::<HashingFor<Block>, ReclaimHostFunctions>(config)
+ .run_with_spec::<HashingFor<Block>, ReclaimHostFunctions>(Some(config.chain_spec))
)
```
## 4. Maintenance Change
- `pallet-nis` get a `BenchmarkSetup` config item to prepare its
counterparty asset.
- Add percent progress print when running benchmarks.
- Dont immediately exit on benchmark error but try to run as many as
possible and print errors last.

Improves `adder-collator` to also compute the parachain velocity. The
velocity is defined as number of parachain blocks progressing per relay
chain block.
In this test we're asserting that the elastic parachain always
progresses by 3 blocks per RCB, while the non-elastic parachain
progresses normally - 1 block per RCB.

With Coretime enabled we can no longer assume there is a static 1:1
mapping between core index and para id. This mapping should be obtained
from the scheduler/claimqueue on block by block basis.
This PR modifies `para_id()` (from `CoreState`) to return the scheduled
`ParaId` for occupied cores and removes its usages in the code.

The XCM builder pattern lets you build xcms like so:
```rust
let xcm = Xcm::builder()
.withdraw_asset((Parent, 100u128).into())
.buy_execution((Parent, 1u128).into())
.deposit_asset(All.into(), AccountId32 { id: [0u8; 32], network: None }.into())
.build();
```
All the `.into()` become quite annoying to have to write.
I accepted `impl Into<T>` instead of `T` in the generated methods from
the macro.
Now the previous example can be simplified as follows:
```rust
let xcm = Xcm::builder()
.withdraw_asset((Parent, 100u128))
.buy_execution((Parent, 1u128))
.deposit_asset(All, [0u8; 32])
.build();
```

closes#1324
#### Problem
Currently, it is possible to accidentally use inner unversioned
migration instead of `VersionedMigration` since both implement
`OnRuntimeUpgrade`.
#### Solution
With this change, we make it clear that value of `Inner` is not intended
to be used directly. It is achieved by bounding `Inner` to new trait
`UncheckedOnRuntimeUpgrade`, which has the same interface (except
`unchecked_` prefix) as `OnRuntimeUpgrade`.
#### `try-runtime` functions
Since developers can implement `try-runtime` for `Inner` value in
`VersionedMigration` and have custom logic for it, I added the same
`try-runtime` functions to `UncheckedOnRuntimeUpgrade`. I looked for a
ways to not duplicate functions, but couldn't find anything that doesn't
significantly change the codebase. So I would appreciate If you have any
suggestions to improve this

When using `schedule_code_upgrade` to change the code of a parachain in
the relay chain runtime, we had already fixed to not set the `GoAhead`
signal. This was done to not brick any parachain after the upgrade,
because they were seeing the signal without having any upgrade prepared.
The remaining problem is that the parachain code is only upgraded after
a parachain header was enacted, aka the parachain made some progress.
However, this is quite complicated if the parachain is bricked (which is
the most common scenario why to manually schedule a code upgrade). Thus,
this pull request replaces `SetGoAhead` with `UpgradeStrategy` to signal
to the logic kind of strategy want to use. The strategies are either
`SetGoAheadSignal` or `ApplyAtExpectedBlock`. `SetGoAheadSignal` sets
the go ahead signal as before and awaits a parachain block.
`ApplyAtExpectedBlock` schedules the upgrade and applies it directly at
the `expected_block` without waiting for the parachain to make any kind
of progress.
Fix "double-weights" for extrinsics, use only the ones benchmarked in
the runtime.
Deprecate extrinsics that don't specify WeightLimit, remove their usage
across the repo.

Rejoice! Rejoice! The story is nearly over.
This PR removes stale migrations, auxiliary structures, and package
dependencies, thus making Rococo and Westend totally free from any
`im-online`-related stuff.
`im-online` still stays a part of the Substrate node and its runtime:
https://github.com/paritytech/polkadot-sdk/blob/0d9324847391e902bb42f84f0e76096b1f764efe/substrate/bin/node/runtime/src/lib.rs#L2276-L2277
I'm not sure if it makes sense to remove it from there considering that
we're not removing `im-online` from FRAME. Please share your opinion.
Runtime release 1.2 includes bumping of the ParachainHost APIs up to
v10, so let's move all the released APIs out of vstaging folder, this PR
does not include any logic changes only renaming of the modules and some
moving around.

Test started failing after

which enabled approval coalescing, that was expected to happen because
the test required an polkadot_parachain_approval_checking_finality_lag
of 0, which can't happen with max_approval_coalesce_count greater than 1
because we always delay the approval for no_show_duration_ticks/2 in
case we can coalesce it with other approvals.
So relax a bit the restrictions, since we don't actually care that the
lags are 0, but the fact the finalities are progressing and are not

The metric records the current protocol_version of the validator that
just connected with the peer_map.len(), which contains all peers that
connected, that has the effect the metric will be wrong since it won't
tell us how many peers we have connected per version because it will
always record the total number of peers
Fix this by counting by version inside peer_map, additionally because
that might be a bit heavier than len(), publish it only on-active
leaves.

This PR adds a new extrinsic `Call::restore_ledger ` gated by
`StakingAdmin` origin that restores a corrupted staking ledger. This
extrinsic will be used to recover ledgers that were affected by the
issue discussed in
https://github.com/paritytech/polkadot-sdk/issues/3245.
The extrinsic will re-write the storage items associated with a stash
account provided as input parameter. The data used to reset the ledger
can be either i) fetched on-chain or ii) partially/totally set by the
input parameters of the call.
In order to use on-chain data to restore the staking locks, we need a
way to read the current lock in the balances pallet. This PR adds a
`InspectLockableCurrency` trait and implements it in the pallet
balances. An alternative would be to tightly couple staking with the
pallet balances but that's inelegant (an example of how it would look
like in [this
branch](https://github.com/paritytech/polkadot-sdk/tree/gpestana/ledger-badstate-clean_tightly)).
More details on the type of corruptions and corresponding fixes
https://hackmd.io/DLb5jEYWSmmvqXC9ae4yRg?view#/
We verified that the `Call::restore_ledger` does fix all current
corrupted ledgers in Polkadot and Kusama. You can verify it here
https://hackmd.io/v-XNrEoGRpe7APR-EZGhOA.
**Changes introduced**
- Adds `Call::restore_ledger ` extrinsic to recover a corrupted ledger;
- Adds trait `frame_support::traits::currency::InspectLockableCurrency`
to allow external pallets to read current locks given an account and
lock ID;
- Implements the `InspectLockableCurrency` in the pallet-balances.
- Adds staking locks try-runtime checks
(https://github.com/paritytech/polkadot-sdk/issues/3751)
**Todo**
- [x] benchmark `Call::restore_ledger`
- [x] throughout testing of all ledger recovering cases
- [x] consider adding the staking locks try-runtime checks to this PR
