RHBA-2012:1319 - dracut bug fix update

Synopsis

dracut bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated dracut packages that fix a bug are now available for Red Hat Enterprise Linux 6 Extended Update Support.

Description

The dracut packages include an event-driven initramfs generator infrastructure based on the udev device manager. The virtual file system, initramfs, is loaded together with the kernel at boot time and initializes the system, so it can read and boot from the root partition.

This update fixes the following bug:

  • If the "/boot/" directory was not on a separate file system, dracut called the sha512hmac utility with a file name prefixed with "/sysroot/boot". Consequently, sha512mac searched for the file checksum in "/boot/", returned errors, and dracut considered the FIPS check to have failed. Eventually, a kernel panic occurred. With this update, dracut uses a symlink linking "/boot" to "/sysroot/boot", sha512mac can now access files in "/boot/", and FIPS checks now pass, allowing the system to boot properly in the described scenario. (BZ#860350)

All users of dracut are advised to upgrade to these updated packages, which fix this bug.
