Isolation Segment v2.10 Release Notes

Page last updated:

This topic contains release notes for Isolation Segment v2.10.

Because VMware uses the Percona Distribution for MySQL, expect a time lag between Oracle releasing a MySQL patch and VMware releasing TAS for VMs containing that patch.

  ## Bug Fixes
  - Removed the x509ignoreCN property. Now that `gorouter` is built on golang 1.17, it
no longer has any effect on gorouter behavior, and was only adding to confusion in
the properties
  - Resolve an issue with route-registrar using the same TTL as it's RegistrationInterval
for tcp routes, leading to unnecessary churn of pruned + re-registered routes.
  - Resolve an issue with Routing API where upserts to tcp routes were causing change
events to be emitted when the only change was a bump in TTL. This led to an issue
where tcp-router was constantly reloading haproxy with every route's heartbeat
registration call.
  ## Manifest Property Changes
  | Job | Property | 0.230.0 | 0.231.0 |
  | --- | --- | --- | --- |
  | `gorouter` | `golang.x509ignoreCN` | false | No longer exists |
  |  `route_registrar` | `golang.x509ignoreCN` | false | No longer exists |
  | `tcp_router` | `golang.x509ignoreCN` | false | No longer exists |

2.10.22

Release Date: 02/28/2022

  • [Feature Improvement] Due to routing-release now being built with Golang 1.17, all certificates provided MUST contain SAN entries on them. The previous workaround of setting “Enable temporary workaround for certs without SANs” will no longer function.
  • [Feature Improvement] Per Golang 1.17’s new and stricter IP parsing standards, any IP addrs with leading zeros in any octets will result in a BOSH template failure to allow operators to remove the leading zeros and try again (affects properties fed into diego-release, garden-runc-release, winc-release, nats-release, and routing-release),.
  • [Bug Fix] Fixes an issue related to the parsing of the X-B3-TraceId and X-B3-SpanId HTTP headers
  • [Bug Fix] Smoke tests support for TLSv1.3 only option
  • Bump cflinuxfs3 to version 0.274.0
  • Bump diego to version 2.58.1
  • Bump garden-runc to version 1.19.33
  • Bump loggregator-agent to version 6.0.8
  • Bump metrics-discovery to version 3.0.8
  • Bump routing to version 0.229.0

Release Date: 02/07/2022

Note: This version of TAS for VMs contains a known issue that can cause application traces to break. See Gorouter Sets an Invalid X-B3-SpanID Header in Known Issues.

  • [Security Fix] Bump routing release to 0.228.0 to address (CVE-2021-44716)
  • [Feature Improvement] Golang v1.17 contains stricter IP parsing standards, so IP addresses with leading zeros in any octets cause a BOSH template failure. Operators can remove the leading zeros and try deploying again. This affects properties that feed into cf-networking-release, silk-release, loggregator-agent-release, and syslog-release. Syslog drains and metric registrar endpoints registered using user-provided services might also be affected.

Release Date: 11/23/2021

  • [Breaking Change] All Gorouter certificates require a SubjectAltName extension. If any Gorouter certificates lack a SubjectAltName, deployment fails.

  • [Breaking Change] This restores the breaking change originally found in 2.10.9 and temporarily remediated in 2.10.10: Gorouter update to Golang v1.15 introduces stricter transfer-encoding header standards. Stricter header standards break Spring apps that incorrectly set the header. For more information, see Applications on TAS for VMs get 502 chunked response error in the Knowledge Base.

  • [Temporary Remediation] Gorouter - Emit log, emit metric, and don’t error when an app response contains a duplicate “Transfer-Encoding: chunked” header.

About Isolation Segment

The Isolation Segment v2.10 tile is available for installation with Ops Manager v2.10.

Isolation segments provide dedicated pools of resources where you can deploy apps and isolate workloads. Using isolation segments separates app resources as completely as if they were in different Ops Manager deployments but avoids redundant management and network complexity. For more information about isolation segments, see Isolation Segments in TAS for VMs Security.

For more information about using isolation segments in your deployment, see Managing Isolation Segments.

How to Install

To install Isolation Segment v2.10, see Installing Isolation Segment.

To install Isolation Segment v2.10, you must first install Ops Manager v2.10.

New Features in Isolation Segment v2.10

Isolation Segment v2.10 includes the following major features:

Aggregate Syslog Drains Contain Logs Only

When you configure an aggregate syslog drain in Isolation Segment v2.10, by default you receive logs only. You do not also receive metrics. By not including metrics alongside logs, your syslog drain uses fewer resources and reduces network traffic between TAS for VMs components and your external logging service.

If you want the aggregate drain to send metrics along with logs, you can modify your drain URLs.

To continue to see metrics in your drains after upgrading to Isolation Segment v2.10:

  1. Navigate to the Ops Manager Installation Dashboard.
  2. Click the Isolation Segment tile in the Installation Dashboard.
  3. Select System Logging.
  4. For Address, enter the hostname or IP address of the syslog server and append ?include-metrics-deprecated=true. For example, https://syslog-server.com:123?include-metrics-deprecated=true.
  5. Click Save.

For more information about configuring aggregate syslog drains, see Configure System Logging in Configuring TAS for VMs.

You can supply sticky session cookie names for the Gorouter to use when handling sticky sessions. The Gorouter uses these cookies to support session affinity, or sticky sessions. For more information, see Session Affinity in HTTP Routing.

By default, the Gorouter uses JSESSIONID. Some apps require a different session name. For example, Spring WebFlux requires SESSION for the session cookie name.

To supply cookie names, see Configure Networking in Installing Isolation Segment.

Breaking Changes

There are no breaking changes in this release of Isolation Segment.

Known Issues

Isolation Segment v2.10 includes the following known issues:

Gorouter Sets an Invalid X-B3-SpanID Header

An issue with the Gorouter’s implementation of X-B3-SpanId and X-B3-TraceId headers can cause invalid span IDs to be set after updating the X-B3-TraceId header to the new 16-byte standard. As a result, some applications and libraries invalidate the X-B3-SpanId value, breaking traces of the application.

This issue affects versions of TAS for VMs that contain routing-release v0.227.0 and v0.228.0.
