Bug Fix Advisory
Severity:
N/A
Issued on:
2014-05-29
Last updated on:

Affected Products:
Red Hat OpenStack 4.0
Details

A new release of the iproute package is now available for Red Hat OpenStack 4.0.

A problem occurred when deleting network namespaces, giving a”Device or resource busy” error, which blocked further namespace usage.Cause: The /var/run/netns directory and all its subdirectories weren’tmounted as shared, preventing unmounting of earlier created networknamespaces as they were copied into the later ones.Consequence: It was sometimes impossible to delete a network namespace evenwhen it was not directly in use.Fix: All netns mounts are now mounted as shared, allowing unmounts topropagate across network namespaces.Result: Deleting a network namespace now only fails if it is directly in use.(BZ#1062685)
