Release 1.1.7

What's New

  • Release actions fixes
  • Fix for a flaky acceptance test

Release 1.1.6

What's New

  • Trust Domain Configuration
  • Controller HA Beta 2

Trust Domain Configuration

OpenZiti controllers from this release forward will now require a trust domain to be configured. High Availability (HA) controllers already have this requirement. HA Controllers configure their trust domain via SPIFFE ids that are embedded in x509 certificates.

For feature parity, non-HA controllers will now have this same requirement. However, as re-issuing certificates is not always easily done. To help with the transition, non-HA controllers will have the ability to have their trust domain sourced from the controller configuration file through the root configuration value trustDomain. The configuration field which takes a string that must be URI hostname compatible (see: https://github.com/spiffe/spiffe/blob/main/standards/SPIFFE-ID.md). If this value is not defined, a trust domain will be generated from the root CA certificate of the controller.

For networks that will be deployed after this change, it is highly suggested that a SPIFFE id is added to certificates. The ziti pki create ... tooling supports the --spiffe-id option to help handle this scenario.

Generated Trust Domain Log Messages

The following log messages are examples of warnings produced when a controller is using a generated trust domain:

WARNING this environment is using a default generated trust domain [spiffe://d561decf63d229d66b07de627dbbde9e93228925], 
  it is recommended that a trust domain is specified in configuration via URI SANs or the 'trustDomain' field

WARNING this environment is using a default generated trust domain [spiffe://d561decf63d229d66b07de627dbbde9e93228925], 
  it is recommended that if network components have enrolled that the generated trust domain be added to the 
  configuration field 'additionalTrustDomains'

Trust domain resolution:

  • Non-HA controllers

    • Prefers SPIFFE ids in x509 certificate URI SANs, looking at the leaf up the signing chain
    • Regresses to trustDomain in the controller configuration file if not found
    • Regress to generating a trust domain from the server certificates root CA, if the above do not resolve

  • HA Controllers

    • Requires x509 SPIFFE ids in x509 certificate URI SANs

Additional Trust Domains

When moving between trust domains (i.e. from the default generated to a new named one), the controller supports having other trust domains. The trust domains do not replace certificate chain validation, which is still checked and enforced.

Additional trust domains are configured in the controller configuration file under the root field additionalTrustDomains. This field is an array of hostname safe strings.

The most common use case for this is field is if a network has issued certificates using the generated trust domain and now wants to transition to a explicitly defined one.

Controller HA Beta 2

This release can be run in HA mode. The code is still beta, as we're still finding and fixing bugs. Several bugs have been fixed since Beta 1 and c-based SDKs and tunnelers now work in HA mode. The smoketest can now be run with HA controllers and clients.

Release 1.1.3

What's New

  • Sticky Terminator Selection
  • Linux and Docker deployments log formats no longer default to the simplified format option and now use logging library defaults: json for non-interactive, text for interactive.

NOTE: This release is the first since 1.0.0 to be marked promoted from pre-release. Be sure to check the release notes for the rest of the post-1.0.0 releases to get the full set of changes.

Stick Terminator Strategy

This release introduces a new terminator selection strategy sticky. On every dial it will return a token to the dialer, which represents the terminator used in the dial. This token maybe passed in on subsequent dials. If no token is passed in, the strategy will work the same as the smartrouting strategy. If a token is passed in, and the terminator is still valid, the same terminator will be used for the dial. A terminator will be consideder valid if it still exists and there are no terminators with a higher precedence.

This is currently only supported in the Go SDK.

Go SDK Example

ziti edge create service test --terminator-strategy sticky

	conn := clientContext.Dial("test")
	token := conn.Conn.GetStickinessToken()
	_ = conn.Close()

	dialOptions := &ziti.DialOptions{
		ConnectTimeout:  time.Second,
		StickinessToken: token,
	}
	conn = clientContext.DialWithOptions("test", dialOptions))
	nextToken := conn.Conn.GetStickinessToken()
	_ = conn.Close()

Component Updates and Bug Fixes

Release 1.1.0

What's New

  • HA Alpha2
  • Deployments Alpha
    • Linux packages provide systemd services for controller and router. Both depend on existing package openziti which provides the ziti command line tool.
      • openziti-controller provides ziti-controller.service
      • openziti-router provides ziti-router.service
    • Container images for controller and router now share the bootstrapping logic with the packages, so they support the same configuration options.

HA Alpha2

This release can be run in HA mode. The code is still alpha, so there are still some bugs and missing features, however basic functionality work with the exceptions noted. See the HA Documementation for instructions on setting up an HA cluster.

Known Issues

  • JWT Session exchange isn't working with Go SDK clients
    • This means Go clients will need to be restarted once their sessions expire
  • Service/service policy changes might not be reflected in routers
    • Changes to policy may not yet properly sync to the routers, causing unexpected behavior with ER/Ts running in HA mode

Release 1.0.0

About 1.0

What does marking OpenZiti as 1.0 mean?

Backwards Compatibility

We've guaranteed API stability for SDK clients for years and worked hard to ensure that routers and controllers would be backwards and forward compatible. However, we have had a variety of management API changes and CLI changes. For post 1.0 releases we expect to make additions to the APIs and CLI, but won't remove anything until it's been first marked as deprecated and then only with a major version bump.

Stability and Scale

Recent releases have seen additional testing using chaos testing techniques. These tests involve setting up relatively large scale environments, knocking out various components and then verifying that the network is able to return to a stable state. These test are run for hours to try and eliminate race conditions and distributed state machine problems.

OpenZiti is also being used as underlying infrastrcture for the zrok public service. Use of this network has grown quickly and proven that it's possible to build ziti native apps that can scale up.

Backward Incompatible Changes to pre-1.0 releases

Administrators no longer have access to dial/bind all services by default. See below for details.

What's New

  • Administrators no longer have access to dial/bind all services by default.
  • TLS Handshakes can now be rate limited in the controller
  • TLS Handshake timeouts can now be set on the controller when using ALPN
  • Bugfixes

DEFAULT Bind/Dial SERVICE PERMISSIONS FOR Admin IDENTITIES HAVE CHANGED

Admin identities were able to Dial and Bind all services regardless of the effective service policies prior to this release. This could lead to a confusing situation where a tunneler that was assuming an Admin identity would put itself into an infinite connect-loop when a service's host.v1 address overlapped with any addresses in its intercept configuration.

Please create service policies to grant Bind or Dial permissions to Admin identities as needed.

TLS Handshake

A TLS handhshake rate limiter can be enabled. This is useful in cases where there's a flood of TLS requests and the controller can't handle them all. It can get into a state where it can't respond to TLS handshakes quickly enough, so the clients time out. They then retry, adding to the the load. The controller ends up wasting time doing work that isn't use.

This uses the same rate limiting as the auth rate limiter.

Additionally the server side handshake timeout can now be configured.

Configuration:

tls: 
  handshakeTimeout: 15s

  rateLimiter:
    # if disabled, no tls handshake rate limiting with be enforced
    enabled: true
    # the smallest window size for tls handshakes
    minSize: 5
    # the largest allowed window size for tls handshakes
    maxSize: 5000
    # after how long to consider a handshake abandoned if neither success nor failure was reported
    timeout: 30s

New metrics:

  • tls_handshake_limiter.in_process - number of TLS handshakes in progress
  • tls_handshake_limiter.window_size - number of TLS handhshakes allowed concurrently
  • tls_handshake_limiter.work_timer - timer tracking how long TLS handshakes are taking
