Topic

An updated gpxe package that fixes two bugs is now available for Red Hat
Enterprise Linux 6.

Description

The gpxe package provides gPXE, an open source Pre-boot Execution Environment
(PXE) implementation and boot loader.

This update fixes the following bugs:

  • The PXE booting did not respect the specified boot order when multiple NICs of

the same type were configured for a virtual machine. Instead, the gPXE image
attempted to boot from all NICs supported by the loaded image in the PCI bus
scan order. This resulted in boot delays, attempting to perform a PXE boot on
unintended devices, as well as in booting from unintended devices in case of
success. This update provides the gPXE boot image with the PCI address of the
intended boot device, ensuring that the image only attempts to boot on the
intended device. (BZ#1057249)

  • HTTP requests generated by gPXE set wrong TCP flag (SYN & PSH) in the first

packet of a session. Consequently, when using a firewall, the TCP packet flow
would be blocked and the HTTP module integrated with gPXE would not work. With
this update, gPXE no longer set the PSH flag in the first packet of a session
and the system now boots as expected. (BZ#1105189)

Users of gpxe are advised to upgrade to this updated package, which fixes these
bugs.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
