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

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 actually sent a very long and detailed letter the DOJ about this and how it constitutes a violation of the Sherman Act. Not Five (5) minutes after sending I received a generic reply about how Microsoft was not in violation of anything.

    With all the E-Mail these people receive and the sheer size of my Letter, there is no way in hell the DOJ read my Letter that fast. What they did was see the word 'Microsoft' and instantly reject it.

    Next week my lawyer is cutting me a deal to rewrite my letter and send it by other means to the right people, we'll see what happens then. Of course I have no money to fight anybody in court, but at least I am trying to get a response that isn't generic.

    That could potentially be an article of its own. Hope you post it everywhere :)
