The creator of systemd wants to bring SecureBoot-enforced hardware attestation to Linux (0pointer.net)

The creator of systemd (Lennart Poettering) has recently created a new company dedicated to bringing hardware attestation to open source software.

What might this entail? A previous blog post could provide some clues:

So, let's see how I would build a desktop OS. The trust chain matters, from the boot loader all the way to the apps. This means all code that is run must be cryptographically validated before it is run. This is in fact where big distributions currently fail pretty badly. This is a fault of current Linux distributions though, not of SecureBoot in general.

If this technology is successful, the end result could be that we would see our Linux laptops one day being as locked down as an Iphone or Android device.

There are lots of others who are equally concerned about this possibility: https://news.ycombinator.com/item?id=46784572

Sorry but this whole thing is just snake-oil.

You can verify and sign your whole trust chain down to the last shared library and it doesn't matter when you don't know what the binary blobs on your TPM / CPU / BIOS / NIC are doing.

The only guarantee to a secure system is openness an all of that signing won't help you there.

Right, so because of your limited knowledge and understanding of what the actual needs of an entire industry are, it's all snake oil. Cool.

Meanwhile I'd just love a way to box up a custom machine, use something what he's building, ship it to site, and have it run without issue and have some piece of mind a competitor didn't try to gank the data over USB, or bypass the identity of the motherboard that SHOULD have boot blocks in place, or maybe someone just rips the SSD right out of it and tries to boot it elsewhere.

Fuck the rest of ALL that and the practical needs of security experts and system builders because YOU are worried that it somehow magically it's used for all kinds of other nefarious things.

Cool. Cool.
