The check for fanout peer inclusion in `test_join` does not check anything since `new_peers` is always empty.

I assume the intention was to fill the `new_peers` with the fanout peers. In this MR I do just that.
Pull-Request: #3628.
Currently, banning peers is a first-class feature of `Swarm`. With the new connection management capabilities of `NetworkBehaviour`, we can now implement allow and block lists as a separate module.
We introduce a new crate `libp2p-allow-block-list` and deprecate `Swarm::ban_peer_id` in favor of that.

Pull-Request: #3590.
In earlier iterations of the design for generic connection management, we removed the `ConnectionId::new` constructor because it would have allowed users to create `ConnectionId`s that are already taken, thus breaking invariants that `NetworkBehaviour`s rely on. Later, we incorporated the creation of `ConnectionId` in `DialOpts` which mitigates this risk altogether.
Thus, it is reasonably safe to introduce a public, non-deprecated constructor for `ConnectionId` that can be used for tests.

This patch deprecates the existing connection limits within `Swarm` and uses the new `NetworkBehaviour` APIs to implement it as a plugin instead.

Allows folks like @bajtos to use the crate, see https://github.com/filecoin-station/zinnia/pull/85.
I opted for not exposing the crate through the `libp2p` meta crate as it is a testing tool only. @thomas
let me know if you prefer me to do so.

Implementation of the libp2p perf protocol according to https://github.com/libp2p/specs/pull/478/.
//CC @MarcoPolo as the author of the specification.
**Don't (yet) expect this to produce reliable performance metrics.**

This modifies the gossipsub implementation to use monotonically increasing sequence numbers for signed messages (as dictated by the specification). There is a discussion about this in #3453. This change will make rust-libp2p gossipsub align with the go-implementation when messages are signed.
Messages will however still use randomized sequence numbers when messages are unsigned for security reasons (as discussed in the issue linked).
This shouldn't change any user-level API, only the seqno behavior. It is fully backwards compatible.
Resolves#3453.

Derive trait `Clone` for `mdns::Event`. This makes cloning its contents without destroying type information possible.

This patch-set introduces `libp2p-swarm-test`. It provides utilities for quick and safe bootstrapping of tests for `NetworkBehaviour`s. The main design features are:
- Everything has timeouts
- APIs don't get in your way
- Minimal boilerplate
Closes#2884.

Instead of relying on `protoc` and buildscripts, we generate the bindings using `pb-rs` and version them within our codebase. This makes for a better IDE integration, a faster build and an easier use of `rust-libp2p` because we don't force the `protoc` dependency onto them.

A large release with lots of changes I am looking forward to. Sorry for the long release cadence.
Anything folks would like to see included that is not yet in `master`? As usual I would like to only block on bug fixes.
Pull-Request: #3491.
Prefixing a variable with an underscore (`_`) in Rust indicates that it is not used. Through refactorings, it can sometimes happen that we do end up using such a variable. In this case, the underscore should be removed.
Clippy can help us with this.
Pull-Request: #3484.
Previously, a `ConnectionHandler` was immediately requested from the `NetworkBehaviour` as soon as a new dial was initiated or a new incoming connection accepted.
With this patch, we delay the creation of the handler until the connection is actually established and fully upgraded, i.e authenticated and multiplexed.
As a consequence, `NetworkBehaviour::new_handler` is now deprecated in favor of a new set of callbacks:
- `NetworkBehaviour::handle_pending_inbound_connection`
- `NetworkBehaviour::handle_pending_outbound_connection`
- `NetworkBehaviour::handle_established_inbound_connection`
- `NetworkBehaviour::handle_established_outbound_connection`
All callbacks are fallible, allowing the `NetworkBehaviour` to abort the connection either immediately or after it is fully established. All callbacks also receive a `ConnectionId` parameter which uniquely identifies the connection. For example, in case a `NetworkBehaviour` issues a dial via `NetworkBehaviourAction::Dial`, it can unambiguously detect this dial in these lifecycle callbacks via the `ConnectionId`.
Finally, `NetworkBehaviour::handle_pending_outbound_connection` also replaces `NetworkBehaviour::addresses_of_peer` by allowing the behaviour to return more addresses to be used for the dial.

Don't close the stream `protocol::recv`.
This is a short-term fix for #3298.
The issue behind this is a general one on the QUIC transport when closing streams, as described in #3343. This PR only circumvents the issue for identify. A proper solution for our QUIC transport still needs more thought.
Pull-Request: #3344.
We create the `ConnectionId` for the new connection as part of `DialOpts`. This allows `NetworkBehaviour`s to accurately track state regarding their own dial attempts.
This patch is the main enabler of https://github.com/libp2p/rust-libp2p/pull/3254. Removing the `handler` field will allow us to deprecate the `NetworkBehaviour::new_handler` function in favor of four new ones that give more control over the connection lifecycle.
Most of this is trivial, apart from the rename of the `clippy::derive_hash_xor_eq` lint to `clippy::derived_hash_with_manual_eq`.
Instead of allowing that lint, we manually implement `PartialEq` and add a comment why the difference between the `PartialEq` and `Hash` implementations are okay.
Previously, we used the full reference to the `OutEvent` of the `ConnectionHandler` in all implementations of `NetworkBehaviour`. Not only is this very verbose, it is also more brittle to changes. With the current implementation plan for #2824, we will be removing the `IntoConnectionHandler` abstraction. Using a type-alias to refer to the `OutEvent` makes the migration much easier.
Previously, inbound connections that happened to resolve to our own `PeerId` were reported as `WrongPeerId`. With this patch, we now report those in a dedicated `LocalPeerId` error.
Related: #3205.
The gossipsub tests are calling lifecycle functions of the `NetworkBehaviour` that aren't meant to be called outside of `Swarm`. This already surfaced as a problem in https://github.com/libp2p/rust-libp2p/pull/3327 and it is coming up again in https://github.com/libp2p/rust-libp2p/pull/3254 where `new_handler` gets deprecated.
Try to mitigate that by constructing a dummy handler instead. Functionally, there is no difference as in both cases, the given handler has never seen a connection.
Storing `NetworkBehaviourAction`s within the behaviour is more flexible than only storing `OutEvent`s. Additionally, I find expression-oriented code easier to reason about because it typically doesn't contain side-effects.
With this commit `libp2p-autonat` no longer discards the whole remote payload in case an addr is unparsable, but instead logs the failure and skips the unparsable multiaddr.
See libp2p#3244 for details.
Instead of offering a public constructor, users are now no longer able to construct `ConnectionId`s at all. They only public API exposed are the derived traits. Internally, `ConnectionId`s are monotonically incremented using a static atomic counter, thus no two connections will ever get assigned the same ID.
The trick with this one is to use `futures::Either` everywhere where we may wrap something that implements any of the `futures` traits. This includes the output of `EitherFuture` itself. We also need to implement `StreamMuxer` on `future::Either` because `StreamMuxer`s may be the the `Output` of `InboundUpgrade`.
It doesn't appear that https://github.com/rust-lang/rust-clippy/issues/10061 is going to be fixed any time soon. In the meantime, our CI is "red" which is misleading because we purposely don't require this CI check. It will however hit stable in ~ 2 weeks at which point our required clippy CI check will fail.
Suppress clippy lint with an `allow` to make it pass.
With this commit `libp2p-dcutr` no longer discards the whole remote payload in case an addr is unparsable, but instead logs the failure and skips the unparsable multiaddr.
