[#7966]: Fix XCM Barrier Rejection Handling to Return Incomplete with Weight

This PR addresses an issue with the handling of message execution when blocked by the barrier. Instead of returning an Outcome::Error, we modify the behaviour to return Outcome::Incomplete, which includes the weight consumed up to the point of rejection and the error that caused the blockage.

This change ensures more accurate weight tracking during message execution, even when interrupted. It improves resource management and aligns the XCM executor’s behaviour with better error handling practices.

[#8198]: Remove #[no_mangle] from the panic handler

Fixes #8190

Remove useless #[no_mangle] from the panic handler which screws up the panic handling machinery on recent versions of Rust.

[#7866]: Make litep2p the default backend in Kusama

A new trait IdentifyNetworkBackend is introduced for the polkadot-service. The purpose of the trait is to specify the default network backend for individual chains. For Kusama based chains, the default is now litep2p. For other chains, the default remains unchanged to libp2p.
The network backend field of the network configuration is made optional to accommodate for this change.

[#7075]: Snowbridge - Ethereum Electra Upgrade Support

Adds support for the Ethereum Electra hard-fork in the Ethereum light client. Maintains backwards compatibility with the current Deneb hard-fork.

[#7856]: Fix XCM decoding inconsistencies

This PR adjusts the XCM decoding logic in order to deduplicate the logic used for decoding v3::Xcm, v4::Xcm and v5::Xcm and also to use decode_with_depth_limit() in some more places.

[#7968]: Fix XCM Barrier Rejection Handling to Return Incomplete with Weight

This PR addresses an issue with the handling of message execution when blocked by the barrier. Instead of returning an Outcome::Error, we modify the behaviour to return Outcome::Incomplete, which includes the weight consumed up to the point of rejection and the error that caused the blockage.

This change ensures more accurate weight tracking during message execution, even when interrupted. It improves resource management and aligns the XCM executor’s behaviour with better error handling practices.

[#7899]: Remove execute_with_origin implementation in the XCM executor

The XCM executor will not support the ExecuteWithOrigin instruction from the start.
It might be added later when more time can be spent on it.

[#7921]: Use non-native token to benchmark on asset hub

Asset Hub was using the native token for benchmarking xcm instructions. This is not the best since it's cheaper than using something in pallet-assets for example.
Had to remove some restrictive checks from pallet-xcm-benchmarks.

[#7738]: Introduce filter to restrict accounts from staking

Introduce an associated fn filter in pallet-staking to restrict some accounts from staking.
This is useful for restricting certain accounts from staking, for example, accounts staking via pools.

[#7760]: Dynamic uncompressed code size limit

Deprecates node constant VALIDATION_CODE_BOMB_LIMIT and introduces validation_code_bomb_limit runtime API that computes the maximum uncompressed code size as the maximum code size multiplied by a compression ratio of 10.

[#7694]: XCM: Process PayFees only once

The PayFees instruction should only ever be used once. If it's used more than once, it's just a noop.

[#8051]: XCM: Some weight fixes for InitiateTransfer

• Added some base weight for InitiateTransfer no matter what.
• Short circuit on AllCounted(0) to not have to go through all fungibles.

[#7689]: Fix DryRunApi client-facing XCM versions

Fixes #7413

This PR updates the DryRunApi. The signature of the dry_run_call is changed, and the XCM version of the return values of dry_run_xcm now follows the version of the input XCM program.

It also fixes xcmp-queue's Router's clear_messages: the channel details first_index and last_index are reset when clearing.

[#7894]: [stable2412] pallet-revive: remove related crates from umbrella

Fixes polkadot-sdk building for stable2412. It removes its dependency on pallet-revive* crates, which aren't publishable as part of stable2412 release & patch releases. Minor updates were brought to a bunch of other crates to allow their compilation in test profile, to enable granular testing and rapid feedback of crates for next stable2412 patch releases.

[#7866]: Make litep2p the default backend in Kusama

This PR makes the litep2p backend the default network backend in Kusama, but also for system chains.
We performed a gradual rollout in Kusama by asking validators to manually switch to litep2p.
The rollout went smoothly, with 250 validators running litep2p without issues. This PR represents the next step in testing the backend at scale.

Asset Hub Next (Westend)

Asset Hub Next

The migration of staking, governance, balances and other related pallets from the Relay Chain to Asset Hub is currently in development (part of the Plaza project and RFC-32) and dubbed AHM (Asset Hub Migration).

We are introducing a new temporary parachain on Westend which represents the future functionality of Asset Hub ready to test against for ourselves and other stakeholders who will be integrating with it, while we finalise the actual migration for Westend. By having two asset hubs on Westend in the lead up to the transition, we can have the old runtime and future runtime live at the same time, and crucially the future runtime is live much earlier that would otherwise be possible.

This is deployed and running as of today. The parachain is registered with para_id 1100 and is now ready to test. Note that the state is more or less empty, as the migration logic is still being finalised. When the migration happens we will migrate the relay pallets and state to Westend Asset Hub and Asset Hub Next will be retired shortly afterwards.

Public endpoints

RPC: wss://westend-asset-hub-next-rpc.parity-chains-scw.parity.io
Sidecar: https://westend-asset-hub-next-sidecar.parity-chains-scw.parity.io/

Artifacts

The genesis chainspec includes some injected staking data, and so it is quite large, especially in its raw format. Instead the following instructions can be followed to get the necessary information all from the attached plaintext chain-spec.

This assumes that you have the polkadot-omni-node and chain-spec-builder in your path, both can be compiled from the sdk repo or downloaded from a previous release. You can download ah-next-chain-spec.json from this release, and from the same working directory run:

chain-spec-builder convert-to-raw ah-next-chain-spec.json && mv chain_spec.json ah-next-chain-spec-raw.json
polkadot-omni-node export-genesis-head --chain ah-next-chain-spec-raw.json > ah-next-genesis-head
polkadot-omni-node export-genesis-wasm --chain ah-next-chain-spec-raw.json > ah-next-genesis.wasm

Which generates the genesis wasm and head data, as well as the raw chain spec (for running with zombienet or similar)

Polkadot stable2412-2

This release contains the changes from polkadot-stable2412-1 to polkadot-stable2412-2.

ℹ️ Please note:

This is a patch release for the latest stable version: stable2412. If your nodes are already running on this version you can consider to upgrade to it to have latest fxes.

The tag corresponding to the current patch release polkadot-stable2412-2 and matching the old pattern will be available under polkadot-v1.17.2.

[#7605]: Fix issue with InitiateTransfer and UnpaidExecution

Fix issue where setting the remote_fees field of InitiateTransfer to None could lead to unintended bypassing of fees in certain conditions. UnpaidExecution is now appended after origin alteration. If planning to use UnpaidExecution, you need to set preserve_origin = true.
The AllowExplicitUnpaidExecutionFrom barrier now allows instructions for receiving funds before origin altering instructions before the actual UnpaidExecution. It takes a new generic, Aliasers, needed for executing AliasOrigin to see if the effective origin is allowed to use UnpaidExecution. This should be set to the same value as Aliasers in the XCM configuration.

[#7451]: omni-node: Adjust manual seal parameters

This PR restores compatibility of older runtimes with the dev mode of omni-node. Before, runtimes built without the changes in #6825 were failing.

[#7365]: Use checked math in frame-balances named_reserve

This PR modifies named_reserve() in frame-balances to use checked math instead of defensive saturating math.

The use of saturating math relies on the assumption that the value will always fit in u128::MAX. However, there is nothing preventing the implementing pallet from passing a larger value which overflows. This can happen if the implementing pallet does not validate user input and instead relies on named_reserve() to return an error (this saves an additional read)

This is not a security concern, as the method will subsequently return an error thanks to <Self as ReservableCurrency<_>>::reserve(who, value)?;. However, the defensive_saturating_add will panic in --all-features, creating false positive crashes in fuzzing operations.

[#7462]: Update SCALE codec indices

We need this in order to be able to update parity-scale-codec to the latest version after it's released. That's because parity-scale-codec added support for checking for duplicate indexes at compile time.

Changelog for Runtime Dev

ℹ️ These changes are relevant to: All of those who rely on the runtime. A parachain team that is using a pallet. A DApp that is using a pallet. These are people who care about the protocol (WASM, not the meta-protocol (client).)

[#7243]: transfer function Preservation is changed to Expendable in fungible and fungibles adapter

The Preservation of transfer method of fungible and fungibles adapters is changed from Preserve to Expendable. So the behavior of the TransferAsset will be consistent with the WithdrawAsset function, as in fungible and fungibles adapter.

[#7365]: Use checked math in frame-balances named_reserve

This PR modifies named_reserve() in frame-balances to use checked math instead of defensive saturating math.

The use of saturating math relies on the assumption that the value will always fit in u128::MAX. However, there is nothing preventing the implementing pallet from passing a larger value which overflows. This can happen if the implementing pallet does not validate user input and instead relies on named_reserve() to return an error (this saves an additional read)

This is not a security concern, as the method will subsequently return an error thanks to <Self as ReservableCurrency<_>>::reserve(who, value)?;. However, the defensive_saturating_add will panic in --all-features, creating false positive crashes in fuzzing operations.

[#7461]: Update SCALE codec indices

We need this in order to be able to update parity-scale-codec to the latest version after it's released. That's because parity-scale-codec added support for checking for duplicate indexes at compile time.

[#7322]: Bridges: emulated tests small nits/improvements

This PR removes the use of open_bridge_between_asset_hub_rococo_and_asset_hub_westend. This function was used in the generic test_dry_run_transfer_across_pk_bridge macro, which could cause compilation issues when used in other contexts (e.g. fellows repo).

[#7383]: Bridges small nits/improvements

This PR contains small fixes and backwards compatibility issues identified during work on the larger PR: #6906.

[#7437]: Remove dead code

Remove unused code

[#7307]: Bridges small nits/improvements

This PR introduces a new expected_payload_type parameter to the Bridges assert_complete_bridge_types macro.
