@JourneymanGeek Looks like "bias lighting" is just poor-man's ambilight

@Bob It looks like Bitlocker was specifically designed to prevent that sort of attack

Tom Wijsman

@qasdfdsaq I love you too. <3

> By default, BitLocker seals keys to the measurements of the Core Root of Trust Measurement (CRTM), the BIOS and any platform extensions, option ROM code, MBR code, the NTFS boot sector, and the boot manager. If any of these items are changed unexpectedly, BitLocker will lock the drive and prevent it from being accessed or decrypted.

Seems that bitlocker is implicitly secure boot on steroids

I'll take it!

Particularly since it works with dynamic disks and doesn't require GPT

Now to try install Windoof 10

Journeyman Geek

@TomWijsman oh, yeah

For a little while at least ;)

@qasdfdsaq O_O

Tom Wijsman

Conspiracy wise, I see how this is a bait to get me back active on Super User. :-P

qasdfdsaq

@Bob Why O_O?

Journeyman Geek

13:24

hm. I probably need to replace my powerstrips eventually too.

Ugh.

Bob

@qasdfdsaq The only question I have about that is: what happens if bitlocker itself were replaced?

qasdfdsaq

Shit, he's figured it out!

Bob

Though that would be a very difficult job at best.

Journeyman Geek

@qasdfdsaq I didn't even know you knew @TomWijsman ;p

qasdfdsaq

@Bob I assume "Bitlocker itself" is part of the bootloader chain which is verified

Bob

13:25

@qasdfdsaq That would require something in the firmware (secure boot? tpm? I dunno) to perform the verification. If you have that, then everything's good.

But if unverified code is executed at any point before bitlocker runs, well...

qasdfdsaq

That's the whole point of the TPM though

Bob

Yep.

Journeyman Geek

Entirely unrelatedly....

Building the Steam Controller

►

qasdfdsaq

It's supposed to verify all code, including even the BIOS

(Which is why BIOS updates will routinely trip Bitlocker recovery)

Bob

Ya. Now I can't remember if there's any reasons against using the TPM :P

qasdfdsaq

13:27

And ultimately that's basically the main attack avenue I need protection from, so looks like BL is all good

I don't really need secure boot

DavidPostill

@qasdfdsaq "changed his name to 'fuq': An interesting choice of name when you say it out loud ;)

qasdfdsaq

@DavidPostill JmG did describe it as... "marginal" the first time he mentioned it ;)

Evidently BitLocker TPM already does the parts of Secure Boot that I want, and not the bits I don't.

Though it's odd that Secure Boot requires EFI+GPT whereas Bitlocker does not

Possibly because Secure Boot is part of EFI and doesn't require a TPM, so the TPM is, I guess, replacing some functionality of the EFI

Bob

@qasdfdsaq Not so odd, if you consider that Secure Boot was designed to work with multiple bootloaders, and allow the bootloaders to change as necessary (as long as they're signed). If the TPM is checking changes from the 'sealed' state and not for signatures, then it's more secure but less flexible.

Two different tasks.

qasdfdsaq

Yeah, I suppose

In a single-OS scenario the high-level functionality seems similar, but you're right

You could boot multiple OS's with secure boot, as long as they're all signed, but not TPM

Bob

The TPM also sounds like it would have a bigger performance penalty, if it needs to verify more code at once. Probably minor.

qasdfdsaq

13:31

I want EFI because my machine boots about 10 seconds quicker with it :-/

Bob

That's odd...

Why would the pre-bootloader stage take 10 secs? o.O

qasdfdsaq

Not really, that's kinda one of the main objectives

Bob

Option ROMs (RAID, etc.)? Some really slow hardware initialisation/scanning?

Slow-loading CSM?

qasdfdsaq

Maybe

Option ROMs in particular do slow down my desktop in CSM mode

Hmm, looks like you can still use Software RAID mirroring with GPT disks in EFI systems on Windows Server

Not sure if it works on Windows 10 client, but I don't see why not.

However there's still the downside that it breaks portability between all my other computers, which are all exclusively legacy-MBR boot

Not that they have to be, they all support EFI... Maybe it's time to make the switch

Bob

@qasdfdsaq Do you often swap boot drives?

qasdfdsaq

13:34

Yes. And clone them as well.

Though the new laptop makes it a lot harder, so I won't be doing it as often

My previous two laptops both had hot-swappable trays

Bob

@qasdfdsaq How does swapping drives (between computers?) help?

I have a hard enough time getting drivers working on one machine, let alone multiple at once :P

qasdfdsaq

Well, not having to maintain multiple OSs when you need to swap hardware

Bob

Hm.

qasdfdsaq

Meh, when they're all running recent Intel platforms the drivers swap seamlessly

Bob

I want to move to a more lightweight install.

qasdfdsaq

13:36

When the drive in my last laptop failed, I took a Windows-RAID-ed mirror out of my desktop, put it in to the laptop, and it booted up first time.

Bob

I've got a whole lot of crap installed here, which makes me not want to touch it and not want to upgrade.

Must be nice having an install you can easily rebuild in a couple hours.

qasdfdsaq

That's one great benefit of Windows software-RAID, you can just take an instant snapshot of an entire OS and restore it in minutes.

Course it makes incremental backups hard, with 100GB+ images each time.

But ZFS has block level deduplication

That's also my main driver for wanting 10GbE

I seriously wonder how badly Bitlocker and software RAID might interact though. I know it was a complete no-go when used with Truecrypt

Hennes

10GbE might just use a tad too much power to ever find it in laptops.

qasdfdsaq

Thankfully, Thunderbolt includes it, and is finding its way into more and more laptops already

Sadly, mine's just a few months too old to have it :(

Bob

@qasdfdsaq I'd actually expect them to work together fairly well. Microsoft is usually decent at integrating their own software.

qasdfdsaq

13:42

In fact Thunderbolt 3 provides 40Gb, but 10GbE emulation is mandatory.

Hennes

Is expresscard to thunderbolt an option?

qasdfdsaq

@Bob TBH booting off software RAID on GPT is a not-officially-supported configuration anyway

@Hennes Probably, but in a limited fashion

Expresscard doesn't provide enough lanes for full bandwidth

But there are Thunderbolt cards that connect to even SATAe ports

Basically the controller is a standard PCIe device, so any PCIe port could theoretically have a thunderbot HBA at the end of it

You might not see it called Thunderbolt though, as that requires Intel-specific certification

Bob

@qasdfdsaq ...welp.

qasdfdsaq

@Bob Oh come on, we're superusers here ;)

If all we did was stuck to officially supported enterprise-certified configurations we may as well turn into ~~Server~~ ClientFault

Bob

@qasdfdsaq Heh, I try to keep my data on supported configurations.

qasdfdsaq

13:49

ZFS on Linux ;)

Bob

Except that root-on-ZoL install. (cc @allquixotic)

qasdfdsaq

ZoL itself isn't even supported, let alone root/boot

Bob

Yep.

qasdfdsaq

Although whether any form of ZFS is supported anymore outside of Oracle Solaris is debatable

Bob

@qasdfdsaq Oh, I think I have a pretty stable boot method.

It's an EFI boot straight to a kernel EFIstub.

The main ZoL kernel code is used.

Far better than messing around with getting GRUB to understand ZFS... shudder

qasdfdsaq

13:51

I wonder if ZoL is still considered a fork of Illumos ZFS or if OpenZFS is considered the "master" now

Heh, nice

Yeah getting Grub to understand ZFS has never been easy

Hennes

All bow to the holy master <strike>Hypnotoad</strike> ZFS

qasdfdsaq

That said, you could do the same thing as Linux's Bitlocker equivalent does

Bob

What was that... dm-crypt?

qasdfdsaq

Something like that

LUKS wrapped

AKA kernel image and initrd in a separate boot partition

TBH even mainline Linux uses that as default

Bob

@qasdfdsaq That's what I have. Those sit on a flash drive, actually.

qasdfdsaq

13:53

Ah

Bob

EFI boot requires FAT, so... yea.

Hennes

Sort off

It allows lots of filesystem, but ony requires support for one

Bob

Choice between having a single FAT partition on one drive, having a mirrored (md) partition, or chucking it on a separate drive.

Hennes

Which allows Apply to add support for HFS, abnd use a HFS formatted system partition.
all the while claiming to be complaiant

Bob

The flash drive was cheap. And it's only ever accessed (read-only) on boot, so should last more or less forever.

@Hennes This is a Supermicro machine ... I'm surprised it even works with FAT.

Hennes

13:56

SuperMicro. Both great and awful.

Best servers for value ever

And you get what you pay for

qasdfdsaq

Meh, I trust "flash drives" even less than I trust SSDs

Bob

@qasdfdsaq Worst case, it dies, I get them to replace it, and I just create a FAT partition and copy two files across (which is scripted anyway).

I'll take that over the increased complexity of dealing with another partition on the same disks as ZFS.

qasdfdsaq

> The UEFI specification requires MBR partition tables to be fully supported.[3] However, some UEFI implementations immediately switch to the BIOS-based CSM booting upon detecting certain types of partition table on the boot disk, effectively preventing UEFI booting to be performed from EFI System partitions contained on MBR-partitioned disks.[4]

Bleurgh

Hennes

In other words: firmware is still poorly written by some manufacturers.

qasdfdsaq

Gah this laptop is going to be a pain to experiment with EFI with

It's an utter pain to remove the disks, it has crappy wireless, and no GbE.

I can image and restore disks at 5Gbps on my old laptop. I can image and restore disks at 0.05Gbps on this new one ._.

Grr why does Microsoft Media Creation Tool take a literal hour

Hennes

14:08

Restore the disk in an external disk dock?

Bob

@qasdfdsaq No GbE?!

Hennes

3.0GB/sec should be easy that way

Bob

Or is that no (wired) Ethernet at all?

qasdfdsaq

@Hennes That requires spending 20 minutes unscrewing a pile of torx screws to get at the drive.

@Bob No wired at all

Hennes

Now that is weird.

Bob

14:08

@qasdfdsaq Oh. That's a bit better.

qasdfdsaq

I had considered the HP equivalent that was £350 cheaper but that has only 10/100 Ethernet

Which may as well be none.

Bob

100Mbit-only and it'd be defenestration material.

...as I was saying.

qasdfdsaq

@Hennes Most modern laptops are built to be thin, not to be serviceable

Hennes

No GB I understand. Most user want the fastest thing there is, but they also want long battery life (and 100mbit/sec eiternet is plenty for facebooking)

Bob

@qasdfdsaq At least it's not glue.

My HP business laptop has twice the expandability in a smaller case though.

qasdfdsaq

The HP just has a tool-free latch to remove the entire bottom cover

Hennes

Use a sata extension cable and an external SATA dock (taped to the laptop) ?

Ohnana

review audits are satan

qasdfdsaq

Windows 10 installer doesn't appear to let you follow Microsoft's guidance for setting up a bitlocker-ready install

DavidPostill

@Ohnana In my experience, review audits are almost always obvious as they take longer to load than a normal review ... ;). If I see "loading item ..." then I know it's an audit.

qasdfdsaq

And the default partition layout is vastly different to that suggested

Bob

:S

qasdfdsaq

14:33

Also I have no clue how EFI systems interact with partitioned USB booting. Or what happens if you try putting GPT on a USB stick

DavidPostill

I just had one (a fake spam or vandalism audit). 15s to load instead of maybe 1 or 2s.

Bob

@qasdfdsaq Depends on the firmware. There is no general answer.

Some will not even detect the ESP on a removable device.

I think they're getting better about that lately, though.

You're basically stuck with trying and finding out :P

Isn't EFI supposed to be a standard though?

@qasdfdsaq Doesn't that lock the 'digital entitlement' to the machine?

Aha!

Section 3.5.1.2 Non-removable Media Boot Behavior

qasdfdsaq

I'm yet to find my Windows 7 key

Bob

> If a system does not support boot option recovery, then default boot processing will consist of the
boot manager searching non-removable media that supports the
EFI_SIMPLE_FILE_SYSTEM_PROTOCOL or EFI_BLOCK_IO_PROTOCOL. In general the
boot manager will search all candidate media but platform policy may optionally limit the search to
a subset of all possible devices connected to a given system; choices for such policy limits are
implementation specific. If the device supports the EFI_SIMPLE_FILE_SYSTEM_PROTOCOL

So the specs specifically define behaviour for non-removable media.

...I'm not seeing a section for removable media :S

qasdfdsaq

Hmm

Bob

Oh it's 3.5.1.1

how'd I miss that

> On a removable media device it is not possible for the FilePath to contain a file name, including
sub directories. FilePathList[0] is stored in non volatile memory in the platform and cannot
possibly be kept in sync with a media that can change at any time.

Hm... if I'm reading this right...

If the removable device is not a filesystem but instead a block IO device then ... it'll do something with drivers? :S

12.3.4.1

Ugh.

qasdfdsaq

Interesting

Bob

Ok. @qasdfdsaq from what I can gather, removable media should not have a partition table. At the same time, it does have the option of falling back to drivers that do unknown things. And then there is no defined way to actually detect something as removable so it would be legal for the implementation to consider a removable device as two separate removable and non-removable entries at once.

I think.

qasdfdsaq

I wonder if the EFI shell will allow one to manually specify an executable to boot other than the one in boot

Bob

My head is spinning.

@qasdfdsaq Usually, yes. Assuming you manage to navigate the crazy syntax and driver mappings :S

qasdfdsaq

@Bob I'm pretty sure there is a defined way to identify something as removable and that's to see if its attributes have the removable flag set

Bob

15:07

It might end up being easier to boot into a (uefi) livecd and adding a boot entry with efibootmgr

That's what I did on the Supermicro machine

qasdfdsaq

Uh probably

That's almost certainly gonna be better

Bob

I've never tried that with Windows though. Dunno how the Windows boot entry is to be specified.

qasdfdsaq

Plenty of removable media have partition tables, in fact most come with one by default

Journeyman Geek

isn't removable/non removable a flag?

qasdfdsaq

Point it at a bootloader

Journeyman Geek

15:08

I seem to remember you could switch that on some drives

Bob

@qasdfdsaq I can't see that definition in the standard, though.

qasdfdsaq

@Bob That's cause it's nothing to do with EFI

Bob

@JourneymanGeek USB devices do have a removable/non-removable flag. But if the standard doesn't specify that that flag should be read, then it's really up to the implementation how it wants to consider the drive.

qasdfdsaq

@Bob USB devices, SATA devices, and, well, how else are you going to connect something?

Dunno about Firewire devices but I've never seen a bootable one

Bob

@qasdfdsaq PCI, SCSI, iSCSI, USB...

There's listed SNP, PXE, BIS and HTTP boot. no idea what those do

and I think the standard is actually left open for other devices..?

qasdfdsaq

15:11

SCSI... err, that'll be up to the HBA I suppose

Everyone uses SAS now anyway

PCI... most EFIs before this year couldn't boot off them anyhow

Bob

> RemovableMediaTRUE if the media is removable; otherwise, FALSE.

well that's useful

qasdfdsaq

I wonder if that's actually reusing the removeable media flags of old, when actual media, rather than drives were removable

(Tape drives, floppies, CDs, etc.)

Bob

@qasdfdsaq it does specify floppies

wat.

"how booting from ... removable media is handled ... regardless of ... whether it is removable or not"

That makes perfect sense.

qasdfdsaq

15:16

I suspect the first means, as I was referring to earlier, the re-used removable media flag which is now used to signify some forms of removeable storage, not media.

Bob

@qasdfdsaq That sounds... strangely low, actually.

qasdfdsaq

@Bob Exactly.

Bob

I would've expected higher with liquid nitrogen.

@JourneymanGeek Supposedly easier because only 2 cores and not 4

Admittedly my old CPU would only do 5Ghz on one core, and 4.8 with two-3

Bob

@qasdfdsaq Are there actually only two cores present, or is it two enabled two disabled out of four?

qasdfdsaq

I don't really know these days

Bob

If the latter... it's possible a lower-binned chip is just less stable overall.

qasdfdsaq

I know on the HEDT/E/EP platforms they use a combination of both

Bob

15:19

Best results might be to grab an i7 and disable some cores yourself. If that's even possible.

qasdfdsaq
