v3.0.0

Compare Source

Pion DTLS v3.0.0 is now available. Pion DTLS is a Go implementation of DTLS. It allows for secure communication over UDP. It is commonly used for VPNs, WebRTC and other real-time protocols.

This release includes 115 commits from 17 authors. This release added Connection Identifiers, concurrent handshaking when Accepting inbound connections, Censorship Circumvention and better resilience against packet loss during handshaking.

A special thank you to kevmo314 and hasheddan for all their hard work on making this release happen.

This release contains breaking changes. Please read the following carefully, the breakage can't be caught at compile time. Each change will have a linked commit. Looking at examples/ in the linked commit should show what code you need to change in your application.

Breaking Changes

Before /v2 Pion DTLS would handshake on Server or Client creation. This design caused the Accept implementation to be blocking. A new connection couldn't be accept until the previous one had finished.
This design also doesn't match the crypto/tls implementation in stdlib. This mismatch would cause frustration/confusion for users.

Now the handshaking only occurs when Read,Write or Handshake is called. In most cases users shouldn't notice a difference.
If you do want a Handshake performed without a Read or Write this is the change needed.

Before

  dtlsConn, err := dtls.Client(dtlsEndpoint, dtlsConfig)
  if err != nil {
    // handle error
  }

  // Perform logic from negotiated SRTP Profile
  srtpProfile, ok := dtlsConn.SelectedSRTPProtectionProfile()

After

  dtlsConn, err = dtls.Client(dtlsEndpoint, dtlsEndpoint.RemoteAddr(), dtlsConfig)
  if err != nil {
    // handle error
  }

  err = dtlsConn.Handshake()
  if err != nil {
    // Explicitly perform handshake
  }

  // Perform logic from negotiated SRTP Profile
  srtpProfile, ok := dtlsConn.SelectedSRTPProtectionProfile()

New Features

Connection IDs

Connection IDs is a new feature added to the DTLS protocol itself. This change allows for clients to change IPs/Ports during a session. This allows for devices to roam (like phones) or for low power devices to shut down and reconnect without losing their DTLS session!

Connection ID generation is pluggable via the dtls.Config structure, and a random CID generator with a static size is provided for convenience. A new example has been added to demonstrate this functionality.

For those interested in digging deeper into the full set of changes, the majority of work was done in #​570.

Censorship Circumvention

Software that is used to circumvent censorship like snowflake uses Pion. To block this (and other) software goverments have looked for patterns and differences in Pion DTLS and blocked it.

This new release contains hooks that allows users to randomize and circumvent these blocks. Users can modify ClientHello, ServerHello and CertificateRequest. Users can also smuggle information in a ServerHello/ClientHello RandomBytes.
