Applies to: Virtuozzo 7.0

Virtuozzo Advisory ID: VZA-2018-020

1. Overview

The cumulative Virtuozzo ReadyKernel patch was updated with stability fixes. The patch applies to the Virtuozzo 7.0 kernels 3.10.0-693.1.1.vz7.37.30 (7.0.6) and 3.10.0-693.11.6.vz7.40.4 (7.0.6 HF3).

2. Bug Fixes

  • It was discovered that IPv6 routing tables incorrectly handled routing rules for throw routes. This happened because errors were not propagated properly up to the fib_rules_lookup(). (PSBM-81798)

  • It was discovered that incorrect container state could be reported in /sys/fs/cgroup/ve/CTID/ve.state in some cases, which confused user-space tools. As a result, such a container could remain mounted after ‘shutdown -h now’ was performed in it. (PSBM-82766)
