      Bridges lane id agnostic for backwards compatibility (#5649) · 710e74dd
      Branislav Kontur authored 
      
This PR primarily fixes the issue with
`zombienet-bridges-0001-asset-transfer-works` (see:
https://gitlab.parity.io/parity/mirrors/polkadot-sdk/-/jobs/7404903).

The PR looks large, but most of the changes involve splitting `LaneId`
into `LegacyLaneId` and `HashedLaneId`. All pallets now use `LaneId` as
a generic parameter.

The actual bridging pallets are now backward compatible and work with
actual **substrate-relay v1.6.10**, which does not even known anything
about permissionless lanes or the new pallet changes.



## Important

- [x] added migration for `pallet_bridge_relayers` and
`RewardsAccountParams` change order of params, which generates different
accounts

## Deployment follow ups
- [ ] fix monitoring for
`at_{}_relay_{}_reward_for_msgs_from_{}_on_lane_{}`
- [ ] check sovereign reward accounts - because of changed
`RewardsAccountParams`
- [ ] deploy another messages instances for permissionless lanes - on
BHs or AHs?
- [ ] return back `open_and_close_bridge_works` for another
`pallet-bridge-messages` instance

      [bridges-v2] Permissionless lanes (#4949) · 22100999
      Branislav Kontur authored 
      Relates to:
https://github.com/paritytech/parity-bridges-common/issues/2451
Closes: https://github.com/paritytech/parity-bridges-common/issues/2500

## Summary

Now, the bridging pallet supports only static lanes, which means lanes
that are hard-coded in the runtime files. This PR fixes that and adds
support for dynamic, also known as permissionless, lanes. This means
that allowed origins (relay chain, sibling parachains) can open and
close bridges (through BridgeHubs) with another bridged (substrate-like)
consensus using just `xcm::Transact` and `OriginKind::Xcm`.

_This PR is based on the migrated code from the Bridges V2
[branch](https://github.com/paritytech/polkadot-sdk/pull/4427) from the
old `parity-bridges-common`
[repo](https://github.com/paritytech/parity-bridges-common/tree/bridges-v2)._

## Explanation

Please read
[bridges/modules/xcm-bridge-hub/src/lib.rs](https://github.com/paritytech/polkadot-sdk/blob/149b0ac2

/bridges/modules/xcm-bridge-hub/src/lib.rs#L17-L136)
to understand how managing bridges works. The basic concepts around
`BridgeId` and `LaneId` are also explained there.


## TODO

- [x] search and fix for comment: `// TODO:(bridges-v2) - most of that
stuff was introduced with free header execution:
https://github.com/paritytech/polkadot-sdk/pull/4102` - more info in the
comment
[bellow](https://github.com/paritytech/polkadot-sdk/pull/4427#issuecomment-2126625043)
- [x] TODO: there's only one impl of `EnsureOrigin<Success = Location>`

## TODO - not blocking review

**benchmarking:**
- [x] regenerate all relevant weights for BH/AH runtimes
- [ ] regenerate default weights for bridging pallets e.g.
`modules/messages/src/weights.rs`
- [ ] add benchmarks for `xcm-bridge-hub` pallet
https://github.com/paritytech/polkadot-sdk/issues/5550

**testing:**
- [ ] add xcm-emulator tests for Rococo/Penpal to Westend/Penpal with
full opening channel and sending/receiving `xcm::Transact`

**migrations:**
- [x] add migrations for BridgeHubRococo/Westend
https://github.com/paritytech/parity-bridges-common/issues/2794 (to be
reusable for P/K bridge)
  - [x] check also storage migration, if needed for pallets
  - [ ] migration for XCM type (optional)
  - [x] migration for static lanes to the dynamic (reuse for fellows)

**investigation:**
- [ ] revisit
https://github.com/paritytech/parity-bridges-common/issues/2380
- [ ] check congestion around `LocalXcmChannelManager` and
`OutboundLanesCongestedSignals` impls -
https://github.com/paritytech/polkadot-sdk/issues/5551
  - to be reusable for polkadot-fellows
- return `report_bridge_status` was remove, so we need to `XcmpQueue`
alternative?

      Bridges - changes for Bridges V2 - relay client part (#4494) · 977254cc
      Branislav Kontur authored 
      Contains mainly changes/nits/refactors related to the relayer code
(`client-substrate` and `lib-substrate-relay`) migrated from the Bridges
V2 [branch](https://github.com/paritytech/polkadot-sdk/pull/4427).

Relates to:
https://github.com/paritytech/parity-bridges-common/issues/2976
Companion: https://github.com/paritytech/parity-bridges-common/pull/2988


## TODO
- [x] fix comments

## Questions
- [x] Do we need more testing for client V2 stuff? If so, how/what is
the ultimate test? @svyatonik


- [x] check
[comment](https://github.com/paritytech/polkadot-sdk/pull/4494#issuecomment-2117181144)
for more testing

      [testnet] Add `AssetHubRococo` <-> `AssetHubWestend` asset bridging support (#1967) · 1b1fab0d
      Branislav Kontur authored 
      
## Summary

Asset bridging support for AssetHub**Rococo** <-> AssetHub**Wococo** was
added [here](https://github.com/paritytech/polkadot-sdk/pull/1215), so
now we aim to bridge AssetHub**Rococo** and AssetHub**Westend**. (And
perhaps retire AssetHubWococo and the Wococo chains).

## Solution

**bridge-hub-westend-runtime**
- added new runtime as a copy of `bridge-hub-rococo-runtime`
- added support for bridging to `BridgeHubRococo`
- added tests and benchmarks

**bridge-hub-rococo-runtime**
- added support for bridging to `BridgeHubWestend`
- added tests and benchmarks
- internal refactoring by splitting bridge configuration per network,
e.g., `bridge_to_whatevernetwork_config.rs`.

**asset-hub-rococo-runtime**
- added support for asset bridging to `AssetHubWestend` (allows to
receive only WNDs)
- added new xcm router for `Westend`
- added tests and benchmarks

**asset-hub-westend-runtime**
- added support for asset bridging to `AssetHubRococo` (allows to
receive only ROCs)
- added new xcm router for `Rococo`
- added tests and benchmarks

## Deployment

All changes will be deployed as a part of
https://github.com/paritytech/polkadot-sdk/issues/1988.

## TODO

- [x] benchmarks for all pallet instances
- [x] integration tests
- [x] local run scripts
