Updated tboot packages that fix two bugs are now available for Red Hat Enterprise Linux 6.
The tboot packages provide the Trusted Boot (tboot) open source pre-kernel/VMM module. This module uses Intel Trusted Execution Technology (Intel TXT) to initialize the launch of operating system kernels and virtual machines.
- Due to an error in the underlying source code, a buffer overflow could occur and an attempt to boot the kernel with tboot enabled could fail with the following error:Kernel panic - not syncing: Too many boot init vars at `numbers,'This update applies an upstream patch that corrects this error, and the kernel now boots as expected.
- Prior to this update, the installed README file incorrectly identified the supported kernels. This update corrects this file and ensures that it no longer contains incorrect information.
All users of tboot are advised to upgrade to these updated packages, which fix these bugs.
