Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated docker packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 7 Extras.
Description
Docker is an open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually anywhere.
The docker packages have been upgraded to upstream version 1.10.3, which provides a number of bug fixes and enhancements over the previous version. (BZ#1335597)
This update also fixes the following bugs:
- Previously, the "docker info" command returned an incorrect number of images installed in the docker environment. This bug has been fixed and now "docker info" reports the correct number of images. (BZ#1304808)
- A bug in the way the code got the file descriptor number from an HTTP response caused a substantial number of error messages to be logged from failing to get the correct file descriptor. The way the file descriptor is obtained has now been changed and such error messages are no longer logged. (BZ#1335635)
- In previous versions of docker, you needed to disable SELinux support for container separation if you were using the BTRFS back end. This is no longer required. Having SELinux and BTRFS working together increases the security separation between containers. (BZ#1338894)
- When reading from the sync pipe between docker and libcontainer a new line was left behind unread. As a consequence, containers failed to start with the following error:
"error: read parent: connection reset by peer"
To fix this bug, the code has been changed to read all bytes from the sync pipe, and now containers can be started as usual. (BZ#1339164)
Additionally, this update adds the following enhancement:
- Support for the specific namespaced network sysctl settings for containers has been added to docker. This enhancement allows container orchestration tools to set the sysctl settings before launching processes within the container. (BZ#1260136)
Users of docker are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
