RHBA-2014:1461 - syslinux bug fix update

Synopsis

syslinux bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated syslinux packages that fix several bugs are now available for Red Hat Enterprise Linux 6.

Description

The syslinux packages provide a suite of boot loaders, currently supporting DOS FAT file systems, Linux ext2 and ext3 file systems (EXTLINUX), PXE network boots (PXELINUX), or ISO 9660 CD-ROMs (ISOLINUX). It also includes a tool, MEMDISK, which loads legacy operating systems from these media.

The syslinux packages have been upgraded to upstream version 4.04, which provides a number of bug fixes over the previous version, including a patch that corrects the PXE chain functionality. (BZ#970946)

This update also fixes the following bugs:

  • The pxelinux.0 file incorrectly used a BIOS interrupt call when booting up from a local hard drive through the Pre-Boot Execution Environment (PXE). As a consequence, the booting process became unresponsive. With this update, the behavior of pxelinux.0 has been fixed and PXE booting now functions as expected. (BZ#980671, BZ#1085780)

  • The syslinux-tftpboot program incorrectly installed tftp files into the /tftpboot/ directory. Consequently, these files could not be located and used by the appropriate programs, such as tftp. With this update, tftp files are installed into the /var/lib/tftpboot/ directory as expected. (BZ#989867)

Users of syslinux are advised to upgrade to these updated packages, which fix these bugs.

Solution
