UEFI Secure Boot Pre-Bootloader Rewritten To Boot All Linux Versions

Posted by timothy on from the next-level-reached dept.

hypnosec writes "The Linux Foundation's UEFI secure boot pre-bootloader is still in the works, and has been modified substantially so that it allows any Linux version to boot through UEFI secure boot. The reason for modifying the pre-bootloader was that the current version of the loader wouldn't work with Gummiboot, which was designed to boot kernels using BootServices->LoadImage(). Further, the original pre-bootloader had been written using 'PE/Coff link loading to defeat the secure boot checks.' As it stands, anything run by the original pre-bootloader must also be link-loaded to defeat secure boot, and Gummiboot, which is not a link-loader, didn't work in this scenario. This is the reason a re-write of the pre-bootloader was required and now it supports booting of all versions of Linux." Also in UEFI news: Linus Torvalds announced today that the flaw which was bricking some Samsung laptops if booted into Linux has been dealt with.

    I love the idea of singing motherboards :-) it would be much better than this stupid idea that is being forced on us in order to make more money for M$...

    It'd be loads more fun to troubleshoot as well.

    fur elise - bad ram check
    oh fortuna - check video card

    etc etc.

    Much easier than beep codes and instills a bit of culture too.

    Reminds of the old days when a linux kernel compile would take 6 hours and we were trying some modifications for VIA hardware which required hundreds of tries with minor changes in the driver codes - so we would start the compile with a script to play two different types of music on Error or Success, and then go to sleep.

    If in the middle of the night it was dire straits then we would get up and debug/fix the errors and start a compile again; if it was some soothing instrumental we would continue sleeping knowing that its compiled.

    Standard boot message:
    "Is this the real life?
    Is this just fantasy?
    Caught in a landslide
    No escape from reality..."

    Oh so many lines from that song would make great kernel error messages.

    very very frightening...
