Bumps github.com/libp2p/go-libp2p from 0.9.2 to 0.27.8.

Release notes

Sourced from github.com/libp2p/go-libp2p's releases.

v0.27.8

This patch release contains backports of:

  • updating the qtls dependencies (qtls is quic-go's fork of crypto/tls). The new versions now contain a backport of the Go standard library fix included in the Go 1.20.7 / 1.19.12 release for quic-go's crypto/tls fork: golang/go@2350afd
  • core/crypto: restrict RSA keys to <= 8192 bits: libp2p/go-libp2p#2454. The analogous vulnerability in go-libp2p's crypto package.
  • swarm: don't open new streams over transient connections: libp2p/go-libp2p#2450. This fixes a regression introduced in v0.26.0.

Note that in order to be protected against the DoS attack making use of large RSA keys, it's necessary to update to this patch release AND to use the updated Go compiler (1.20.7 or 1.19.12, respectively).

🔦 Highlights

Smart Dialing

This release introduces smart dialing logic. Currently, libp2p dials all addresses of a remote peer in parallel, and aborts all outstanding dials as soon as the first one succeeds. Dialing many addresses in parallel creates a lot of churn on the client side, and unnecessary load on the network and on the server side, and is heavily discouraged by the networking community (see RFC 8305 for example).

When connecting to a peer we first determine the order to dial its addresses. This ranking logic considers a number of corner cases described in detail in the documentation of the swarm package (swarm.DefaultDialRanker). At a high level, this is what happens:

  • If a peer offers a WebTransport and a QUIC address (on the same IP:port), the QUIC address is preferred.
  • If a peer has a QUIC and a TCP address, the QUIC address is dialed first. Only if the connection attempt doesn't succeed within 250ms, a TCP connection is started.

Our measurements on the IPFS network show that for >90% of established libp2p connections, the first connection attempt succeeds, leading a dramatic decrease in the number of aborted connection attempts.

We also added new metrics to the swarm Grafana dashboard, showing:

  • The number of connection attempts it took to establish a connection
  • The delay introduced by the ranking logic

This feature should be safe to enable for nodes running in data centers and for most nodes in home networks. However, there are some (mostly home and corporate networks) that block all UDP traffic. If enabled, the current implementation of the smart dialing logic will lead to a regression, since it preferes QUIC addresses over TCP addresses. Nodes would still be able to connect, but connection establishment of the TCP connection would be delayed by 250ms.

In a future release (see #1605 for details), we will introduce a feature called blackhole detection. By observing the outcome of QUIC connection attempts, we can determine if UDP traffic is blocked (namely, if all QUIC connection attempts fail), and stop dialing QUIC in this case altogether. Once this detection logic is in place, smart dialing will be enabled by default.

More Metrics!

Since the last release, we've added metrics for:
