Node software version crt-20250526-3346 have been delivered with the following updates:

Description: Memory leak fix for remote-discovered endpoints within DNS-defined origin pools.

Symptoms: Resource exhaustion and instability caused by memory leak due to stale remote endpoint information not being cleaned up during DNS refresh cycles.

Node software version crt-20250526-3345 have been delivered with the following updates:

A Hotfix was Implemented to Address the Bug in the Utility Used to Pull Images in Customer Edge (crio).

Description: Effective with release crt-20250526-3343, we switched the container repository domain to gcr.download.volterra.io from gcr.io. This change has revealed a bug in the crio utility that Customer Edge sites use to download images. As a result, the system may fail to pull images correctly when upgrading from a previous version that used the old address. In this case the versions immediately preceding crt-20250526-3343 the gubernator version has remained the same but referenced from gcr.io.

Symptoms: This issue affects Customer Edge (CE) sites when upgrading from a software version released before crt-20250526-3343 to version crt-20250526-3343 or any subsequent version. The crt-20250526-3343 image was introduced as part of the June 05, 2025 release.

Conditions: This issue affects Customer Edge (CE) sites when upgrading from a software version released before crt-20250526-3343 to version crt-20250526-3343 or any subsequent version.

Fix: To resolve the crio bug, we will publish a new CE software version that includes an updated gubernator image. This is a one-time fix, as the domain change that caused the issue will not happen again, and we have confirmed no other services are affected in the same way.

Node software version crt-20250526-3344 have been delivered with the following updates:

Fixed Incorrect Endpoint References in the Production SRE Configuration.

Description: The production SRE configuration referenced incorrect endpoints, causing SMSv2 production sites to attempt connections to staging infrastructure (download.volterra.us) instead of production endpoints (.io domain). This misconfiguration led to the incorrect connections.

Symptoms: The staging endpoint waferdatasetsprod.download.volterra.us:443 was appearing in the production squid proxy logs.

Conditions: NA

Fix: Includes following updates:

Configuration Update: Updated the SRE production model to reference the correct production endpoints with the .io domain instead of the staging endpoints with the .us domain.

Model Repository Changes: Updated the production version prioritization in the model repository to ensure sites restart with the correct configuration.

Testing and Validation:

• The changes were tested on demo1, CRT, and staging environments to verify their effectiveness.
• Verified older sites, such as CRT 13.60.209.206, to ensure that the migration from .us to .io endpoints was successful for getappparamsraw.

Node software version crt-20240730-2798 have been delivered with the following updates:

Description: This is to fix ephemeral port leak during session teardown to origin server.

Symptoms: Load balancers would report 5xx error after working fine for couple of days.

Condition: Continuous traffic to Origin server with packet transmission during session teardown.

Fix: TCP session to origin server is source IP and source port translated. Source port is allocated when session is setup, and it is released when session is torn down. After the session has been deleted in forwarding plane due to TCP reset or four way teardown, if CE receives a packet from origin servers belonging to same session which was deleted, then a new session entry was created which was leaking port internally and future TCP session would get affected due to this. TCP packet reception after teardown is rare and happens mostly in race case. Fix ensures that in such scenarios we don't leak ports.

Fix: Update envoy with nghttp2 patch to fix this issue and set MAX_CONTINUATIONS in envoy for nghttp2.

Node software version crt-20240329-2727 have been delivered with the following updates:

Description: Due to internal logging mechanism issue, traffic propagation is slow to reach CE Site.

As part of change handling NAT IP update was not atomic, and in race case, forwarding threads could see an inconsistent NAT IP list which could be empty, causing segmentation fault.

Fix: NAT IP list update is made atomic by using a covering structure which holds both IP list and count of IP, making update consistent across forwarding threads.
