Illumio Core What's New and Release Notes 23.2

Combination of factors caused policy sync failure on RHEL 9.x OS VENs (E-115693)

Policy sync failed and an error was thrown when the PCE applied custom iptable rules to VENs installed on RHEL 9.X OS (or later) workloads with iptables-nft-1.8.10 package. The issue stemmed in part from invalid syntax introduced by iptables-nft-1.8.10. This issue is resolved on 22.2.45-9201 VENs and later.

Potential for FQDN-based rules to fail (E-114964)

In an environment implementing an IPv6 nameserver, FQDN-based rules may not have been enforced as expected. This issue is fixed.

VEN installation failed on Amazon Linux 2023 (E-113934)

This issue was caused by a change Amazon made to the format of the release name in the system release file. This issue is fixed.

ICMP code misinterpretation caused false positive tampering error (E-113439)

After misinterpreting a rule specifying the ICMP protocol, the VEN generated a false positive tampering error. This issue was resolved by updating the VEN to normalize ICMP code.

Support for pairing VENs on AWS Workloads with IMDS v2 (E-109528)

This VEN release provides support for pairing VENs on AWS workloads with Instance Metadata Service Version 2 (IMDS v2). This update was necessary to support IMDS v2 session-oriented authentication.
